8 Installing Oracle Management Agent

This chapter describes how you can install Oracle Management Agent (Management Agent). In particular, this chapter covers the following:

Overview

Oracle Management Agent (Management Agent) is one of the core components of Enterprise Manager Cloud Control that enables you to convert an unmanaged host to a managed host in the Enterprise Manager system. The Management Agent works in conjunction with the plug-ins to monitor the targets running on that managed host.

Therefore, at any point in time, if you want to monitor a target running on a host, ensure that you first convert that unmanaged host to a managed host by installing a Management Agent, and then manually discover the targets running on it to start monitoring them.

To install a Management Agent, use the Add Host Targets Wizard that is accessible from within the Enterprise Manager Cloud Control console. Oracle recommends that you use this wizard for the mass-deployment of Management Agents.

Figure 8-1 describes a method to access the Add Host Targets Wizard.

Figure 8-1 Add Host Targets Wizard

Add Host Targets Wizard

The Add Host Targets Wizard is an application that offers GUI-rich, interactive screens. To access it, do one of the following:

The wizard enables you to do the following on multiple hosts across platforms with options to run preinstall and postinstall scripts:


Note:

This chapter only describes how you can deploy a fresh Management Agent using the Add Host Targets Wizard. For information on cloning an existing instance and deploying a Management Agent using a shared instance, refer to Oracle Enterprise Manager Cloud Control Advanced Installation and Configuration Guide.

To monitor a target, you need to add the target to Enterprise Manager Cloud Control either using the Auto Discovery Results page, the Add Targets Manually page, or the discovery wizards offered for the targets you want to monitor.

For information about discovering targets in Enterprise Manager Cloud Control, refer to the chapter on adding targets in the Oracle Enterprise Manager Cloud Control Administrator's Guide.

Once the installation is complete, you will see the following default contents in the agent base directory:

<agent_base_directory>
    |_____core
         |_____12.1.0.2.0
    |_____plugins
    |_____agent_inst
    |_____sbin
    |_____plugins.txt
    |_____plugins.txt.status
    |_____agentimage.properties

Note:

If you want to repoint your existing Management Agents to a new Oracle Management Service (OMS), then you must first deinstall those Management Agents and plug-ins, and then redeploy those Management Agents and plug-ins using the new OMS. This is typically done when you want to move from an Enterprise Manager Cloud Control system in a test environment to an Enterprise Manager Cloud Control system in a production environment.

When you repoint your existing Management Agents to a new OMS, you cannot move the targets monitored by the Management Agents, the target history, and the Management Agent history. The monitored targets and the history data is lost.


Before You Begin

Before you begin installing a Management Agent using the Add Host Targets Wizard, keep these points in mind:


Note:

Instead of installing a Management Agent using the Add Host Targets Wizard, you can choose to install the Management Agent manually, in silent mode. For information on installing a Management Agent in silent mode, refer to Oracle Enterprise Manager Cloud Control Advanced Installation and Configuration Guide.

Prerequisites

This section describes the prerequisites you must meet before installing Management Agents using the Add Host Targets Wizard. In particular, it contains the following:

Meeting Generic Prerequisites

Table 8-1 lists the generic prerequisites you must meet before installing Management Agents using the Add Host Targets Wizard.

Table 8-1 Prerequisites for Installing Oracle Management Agent

Requirement Description

Hardware Requirements

Ensure that you meet the hard disk space and physical memory requirements as described in Chapter 3.

Software Requirements

(For Microsoft Windows) Ensure that you have installed Cygwin 1.7 on the destination host as described in Chapter 6.

Note: While running cygwin.bat in Microsoft Windows Server 2008 and Microsoft Windows Vista, ensure that you invoke it in administrator mode. To do this, right-click the cygwin.bat file and select Run as administrator.

Operating System Requirements

Ensure that you install the Management Agent only on certified operating systems as mentioned in the Enterprise Manager certification matrix available on My Oracle Support.

To access the Enterprise Manager certification matrix, follow the steps outlined in Appendix E.

For information about platforms receiving future support, refer to My Oracle Support note 793512.1.

Note: If you use Oracle Solaris 10, then ensure that you have update 9 or higher installed. To verify whether it is installed, run the following command:

cat /etc/release

You should see the output similar to the following. Here, s10s_u6 indicates that update 6, which is not a supported update level for installation, is installed.

Solaris 10 10/08 s10s_u6wos_07b SPARC

Package Requirements

Ensure that you install all the operating system-specific packages as described in Chapter 4.

User and Operating System Group Requirement

Ensure that you create the required operating system groups and users as described in Chapter 5.

Destination Host Requirements

Ensure that the destination hosts are accessible from the host where the OMS is running.

If the destination host and the host on which OMS is running belong to different network domains, then ensure that you update the /etc/hosts file on the destination host to add a line with the IP address of that host, the fully qualified name of that host, and the short name of the host.

For example, if the fully-qualified host name is example.com and the short name is mypc, then add the following line in the /etc/hosts file:

172.16.0.0 example.com mypc

Destination Host Credential Requirements

Ensure that all the destination hosts running on the same operating system have the same set of credentials. For example, all the destination hosts running on Linux operating system must have the same set of credentials.

The wizard installs the Management Agent using the same user account. If you have hosts running on the same operating system but with different credentials, then have two different deployment sessions.

Permission Requirements

  • Ensure that the agent base directory you specify is empty and has write permission.

  • Ensure that the instance directory is empty and has write permission.

Destination Host Time Zone Requirements

Ensure that the time zones of the destination hosts have been set correctly. To verify the time zone of a destination host, log in to the OMS host, and run the following command:

ssh -l <install_user> <destination_host_name> /bin/sh -c 'echo $TZ'

If the time zone displayed is incorrect, log in to the destination host, and follow these steps:

  1. Run the following commands to set the time zone on the destination host:

    • For Korn shell:

      TZ=<value>

      export TZ

    • For Bourne shell or Bash shell:

      export TZ=<value>

    • For C shell:

      setenv TZ <value>

    For example, in the Bash shell, run the following command to set the time zone to America/New_York:

    export TZ='America/New_York'

    To set the time zone on a destination host that runs on Microsoft Windows, from the Start menu, select Control Panel. Click Date and Time, then select the Time Zone tab. Select your time zone from the displayed drop down list.

    To view a list of the time zones you can use, access the supportedtzs.lst file present in the <AGENT_HOME>/sysman/admin directory of the central agent (that is, the Management Agent installed on the OMS host).

    Note: If you are installing a Management Agent on a host that runs on Microsoft Windows Server 2003, and you encounter an error when you suse the Asia/Kolkata time zone, see the My Oracle Support note 1530571.1.

  2. Restart the SSH daemon.

    If the destination host runs on a UNIX based operating system, run the following command:

    sudo /etc/init.d/sshd restart

    If the destination host runs on a Microsoft Windows operating system, run the following commands:

    cygrunsrv -E sshd

    cygrunsrv -S sshd

  3. Verify whether the SSH server can access the TZ environment variable by logging in to the OMS host, and running the following command:

    ssh -l <install_user> <destination_host_name> /bin/sh -c 'echo $TZ'

Note: If you had ignored a prerequisite check warning about wrong time zone settings during the Management Agent install, you must set the correct time zone on the destination hosts after installing the Management Agents. For information on setting time zones post install, refer After You Install.

sudo/pbrun/sesu/su SSH Requirements

(Only for UNIX)

Ensure that you set the oracle.sysman.prov.agentpush.enablePty property to true in the $<OMS_HOME>/sysman/prov/agentpush/agentpush.properties file, if the privilege delegation tool you are using requires a pseudo terminal for remote command execution via SSH. Most privilege delegation tools such as pbrun, sesu, and su require a pseudo terminal for remote command execution, by default.

Note: If you are using sudo as your privilege delegation tool, and you do not want to set the oracle.sysman.prov.agentpush.enablePty property to true, do one of the following:

  • Include Defaults visiblepw in the /etc/sudoers file, or enter the sudo command with the -S option for Privileged Delegation Setting on the Installation Details page.

    For information on how to access the Installation Details page, see Installation Procedure.

  • Comment out Defaults requiretty in the /etc/sudoers file.

sudo/pbrun/sesu/su Requirements (for Root User)

(Only for UNIX)

  • Ensure that the installing user has the privileges to invoke the id command and the agentdeployroot.sh script as root. Grant the privileges in the configuration file of your privilege delegation tool.

    For example, if you are using sudo as your privilege delegation tool, include the following in the /etc/sudoers file to grant the required privileges:

    oracle ALL=(root) /usr/bin/id, /home/oracle/agentibd/*/agentdeployroot.sh

    Here, oracle is the installing user, and /home/oracle/agentibd is the agent base directory.

  • You do not require the following entry in the /etc/sudoers file for installing a Management Agent. However, the entry is required for performing provisioning and patching operations in Enterprise Manager. Therefore, if you are removing this entry before installing a Management Agent, then ensure that you bring back the entry after installing the Management Agent.

    (root)/oracle/product/oms12c/agent/agent_inst/bin/nmosudo

sudo/pbrun/sesu/su Requirements (for Locked Account User)

(Only for UNIX)

  • Ensure that the installing user has the privileges to invoke /bin/sh as the locked account user. Grant the privileges in the configuration file of your privilege delegation tool.

    For example, if you are using sudo as your privilege delegation tool, include the following in the /etc/sudoers file to grant the required privileges:

    login_user1 ALL=(oracle) /bin/sh

    Here, login_user1 is the SSH log in user, and oracle is the locked account and install user.

    If you do not want to grant privileges to the installing user to invoke /bin/sh as the locked account user, set the oracle.sysman.prov.agentpush.pdpShellOutEnabled property to false, and ensure that the installing user has the privileges to invoke id, chmod, cp, mkdir, rm, tar, emctl, agentDeploy.sh, runInstaller, and unzip as the locked account user. Grant the privileges in the configuration file of your privilege delegation tool.

    For example, if you are using sudo as your privilege delegation tool, include the following in the /etc/sudoers file to grant the required privileges:

    login_user1 ALL=(oracle) /usr/bin/id, /bin/chmod, /bin/cp, /bin/mkdir, /bin/rm, /bin/tar, /home/oracle/agentibd/agent_inst/bin/emctl, /home/oracle/agentibd/*/agentDeploy.sh, /home/oracle/agentibd/*/prereq_stage/core/12.1.0.2.0/oui/bin/runInstaller, /home/oracle/agentibd/*/unzip, /home/oracle/agentibd/*/unzipTmp/unzip

    Here, login_user1 is the SSH log in user, oracle is the locked account and install user, and /home/oracle/agentibd is the agent base directory.

  • You do not require the following entry in the /etc/sudoers file for installing a Management Agent. However, the entry is required for performing provisioning and patching operations in Enterprise Manager. Therefore, if you are removing this entry before installing a Management Agent, then ensure that you bring back the entry after installing the Management Agent.

    (root)/oracle/product/oms12c/agent/agent_inst/bin/nmosudo

Locked Account Requirements

Ensure that the locked account user (oracle) has read permission on the home directory of the login user.

Default SSH Port Requirements

Ensure that the SSH daemon is running on the default port (that is, 22) on all the destination hosts. To verify the port, run the following command:

netstat -anp | grep <port_no>

If the port is a non-default port, that is, any port other than 22, then update the SSH_PORT property in the following file that is present in the OMS home:

$<OMS_HOME>/oui/prov/resources/Paths.properties

PATH Environment Variable Requirements

On the destination host, ensure the following:

  • (For Microsoft Windows) Ensure that the Cygwin software location appears before other software locations in the PATH environment variable. After making it the first entry, restart the SSH daemon (sshd).

  • (For UNIX) On the destination host, ensure that the SCP binaries (for example, /usr/bin/scp) are in the PATH environment variable.

CLASSPATH Environment Variable Requirements

Unset the CLASSPATH environment variable. You can always reset the variable to the original value after the installation is complete.

Software Availability Requirements

Ensure that the software of the Management Agent you want to install is available in Oracle Software Library (Software Library).

  • If you want to install Oracle Management Agent 12c on a host that runs on the same platform as the one on which Oracle Management Service 12c is running, then the Management Agent software for that release and platform is available by default in Software Library. Therefore, no action is required from your end.

  • If you want to install Oracle Management Agent 12c on a host that does not run on the same platform as the one on which Oracle Management Service 12c is running, then ensure that the Management Agent software for the intended platform is downloaded and stored in Software Library, using the Self Update console.

    For information about how to download and apply Management Agent software using the Self Update console, see Meeting Management Agent Software Prerequisites.

Path Validation Requirements

Validate the path to all command locations as described in Appendix B.

Temporary Directory Space Requirements

Ensure that you allocate 400 MB of space for a temporary directory where the executables can be copied.

By default, the temporary directory location set to the environment variable TMP or TEMP is honored. If both are set, then TEMP is honored. If none of them are set, then the following default values are honored: /tmp on UNIX hosts and c:\Temp on Microsoft Windows hosts.

Agent Base Directory Requirements

  • Ensure that the agent base directory you provide is empty and has at least 1 GB of free space.

    If a previously run deployment session had failed for some reason, then you might see an ADATMP_<timestamp> subdirectory in the agent base directory. In this case, either delete the subdirectory and start a new deployment session, or retry the failed session from the Add Host Status page.

  • Ensure that the directory name does not contain any spaces.

  • Ensure that the installing user owns the agent base directory. Ensure that the installer user or the root user owns all the parent directories. Ensure that the root user owns the root directory.

    For example, if the agent base directory is /scratch/OracleHomes/agent, and oracle is the installing user, then the /scratch/OracleHomes/agent directory must be owned by oracle, directories scratch and OracleHomes must be owned by either oracle or root user, and the root directory (/) must be owned by root user.

  • If the agent base directory is mounted, then ensure that it is mounted with the setuid turned on.

Central Inventory (oraInventory) Requirements

  • Ensure that you allocate 100 MB of space for the Central Inventory.

  • Ensure that the central inventory directory is not in a shared file system. If it is already in a shared file system, then create a new inventory in a non-shared file system. You can optionally migrate the products that were previously installed in the shared file system to this new inventory in the non-shared file system.

  • Ensure that you have read, write, and execute permissions on oraInventory on all remote hosts. If you do not have these permissions on the default inventory (typically at /etc/oraInst.loc) on any remote host, then ensure that you specify the path to an alternative inventory location by using one of the following options in the Additional Parameters field of the Add Host Targets Wizard. However, note that these parameters are supported only on UNIX platforms, and not on Microsoft Windows platforms.

    INVENTORY_LOCATION=<absolute_path_to_inventory_directory>

    -invPtrLoc <absolute_path_to_oraInst.loc>

Installing User Requirements

  • If the central inventory owner and the user installing the Management Agent are different, then ensure that they are part of the same group.

  • Also ensure that the inventory owner and the group to which the owner belongs have read and write permissions on the inventory directory.

    For example, if the inventory owner is abc and the user installing the Management Agent is xyz, then ensure that abc and xyz belong to the same group, and they have read and write access to the inventory.

Agent User Account Permissions and Rights (For Microsoft Windows)

(For Microsoft Windows) If you are installing the Management Agent on a Microsoft Windows-based operating system, then ensure that the agent user account has permissions and rights to perform the following:

  • Act as part of the operating system.

  • Adjust memory quotas for a process.

  • Replace process level token.

  • Log in as a batch job.

To verify whether the agent user has these rights, follow these steps:

  1. Launch the Local Security Policy.

    From the Start menu, click Settings and then select Control Panel. From the Control Panel window, select Administrative Tools, and from the Administrative Tools window, select Local Security Policy.

  2. In the Local Security Policy window, from the tree structure, expand Local Policies, and then expand User Rights Assignment.

Permissions for cmd.exe (For Microsoft Windows)

(For Microsoft Windows) If you are installing the Management Agent on a Microsoft Windows-based operating system, then ensure that you grant the cmd.exe program Read and Execute permissions for the user account that the batch job runs under. This is a restriction from Microsoft.

For more information on this restriction and to understand how you can grant these permissions, access the following URL to Microsoft Web site:

http://support.microsoft.com/kb/867466/en-us

Preinstallation/Postinstallation Scripts Requirements

Ensure that the preinstallation and postinstallation scripts that you want to run along with the installation are available either on the OMS host, destination hosts, or on a shared location accessible to the destination hosts.

Browser Requirements

  • Ensure that you use a certified browser as mentioned in the Enterprise Manager certification matrix available on My Oracle Support.

    To access the Enterprise Manager certification matrix, follow the steps in Appendix E.

  • If you use Microsoft Internet Explorer 8 or 9, do the following:

    • Turn off the compatibility view mode. To do so, in Microsoft Internet Explorer, from the Tools menu, click Compatibility View to disable it if it is enabled. Also, click Compatibility View Settings and deregister the Enterprise Manager Cloud Control console URL.

    • Enable XMLHTTP. To do so, from the Tools menu, click Internet Options. Click the Advanced tab, and under the Security heading, select Enable native XMLHTTP support to enable it.


Meeting Management Agent Software Prerequisites

To install a Management Agent on a host, the Management Agent software for the host platform must be available in Oracle Software Library (Software Library). If the Management Agent software is not available, you must acquire it using the Self Update Console.


Important:

If the host on which you want to install a Management Agent runs on the same platform as that of the OMS host, you do not need to acquire the Management Agent software. By default, the Management Agent software for the OMS host platform is available in Software Library.

This section describes how to acquire or update the Management Agent software for different platforms using the Self Update console. In particular, it contains the following:

Acquiring Management Agent Software in Online Mode

If Enterprise Manager has access to My Oracle Support via the Internet, it is said to run in Online Mode.

To verify that Enterprise Manager is running in Online Mode, access the Offline Patching page. To access this page, from the Setup menu, select Provisioning and Patching, then select Offline Patching.


Note:

If Enterprise Manager is running in Offline Mode, refer Acquiring Management Agent Software in Offline Mode for information on acquiring Management Agent software in Offline Mode.

To acquire or update Management Agent software using the Self Update console when Enterprise Manager is running in Online Mode, follow these steps:

  1. Ensure that you have set up Self Update.

    For information on setting up Self Update, see Oracle Enterprise Manager Cloud Control Administration Guide.

  2. From the Setup menu, select Extensibility, then select Self Update.

  3. For Type, select Agent Software, then select Open from the Actions menu. The Agent Software Updates page appears to show the Management Agent software available for different platforms.

  4. Select an update from the list of available updates. All entries other than the one that matches the platform of the OMS host should show their status as Available.

  5. Click Download. The Schedule Download dialog opens.

  6. Select when to download the update. The following options are available:

    • Immediately

    • Later (specified time)

    • Whether or not to send a notification when the download is complete

  7. Click Select. An Enterprise Manager job is created to download the Management Agent software to Software Library.

    Enterprise Manager starts downloading the archive from the Oracle Enterprise Manager store. Wait for the download to complete (when in offline mode, the system starts reading from the specified location).

    When the download is complete, Enterprise Manager displays the Confirmation page.

  8. Once the download is complete, select the Management Agent, then click Apply. This step will stage the Management Agent software in Software Library and make it available to the Add Host Targets wizard, which you will use to install Management Agents on hosts.

Acquiring Management Agent Software in Offline Mode

If Enterprise Manager is not connected to My Oracle Support via the Internet, it is said to run in Offline Mode.

To verify that Enterprise Manager is running in Offline Mode, access the Offline Patching page. To access this page, from the Setup menu, select Provisioning and Patching, then select Offline Patching.


Note:

If Enterprise Manager is running in Online Mode, refer Acquiring Management Agent Software in Online Mode for information on acquiring Management Agent software in Online Mode.

To acquire or update Management Agent software using the Self Update console when Enterprise Manager is running in Offline Mode, follow these steps:

  1. Ensure that you have set up Self Update.

    For information on setting up Self Update, see Oracle Enterprise Manager Cloud Control Administration Guide.

  2. From the Setup menu, select Extensibility, then select Self Update.

  3. On the Self Update home page, click Check Updates. A message is displayed that contains the URL to be accessed to download a catalog of all updates.

  4. From an Internet-enabled computer, download the catalog file using the aforementioned URL.


    Note:

    Do not unzip the file.

  5. Copy the downloaded file to either of the following:

    • To any host that has a Management Agent and EM CLI installed

    • To the Oracle Management Service (OMS) host (EM CLI is configured out of box on the OMS host machine, so no setup is required)

  6. Navigate to the 12.1 MOS home/bin directory and log in to EMCLI, running the command as the install user, for example:

    ./emcli login -username=sysman
    
  7. Perform emcli synchronize (mandatory).

  8. Run the emcli import_update_catalog command to import the archive into the Oracle Management Service instance or the Management Agent you want to update. For example:

    ./emcli import_update_catalog -omslocal  -file=zip file absolute path
    

    Tip:

    For a multi-OMS setup, run emcli help import_update_catalog for more options.

  9. Return to the Self Update home page and do a refresh to see a count of new updates in the Available Updates column.

  10. For Type, select Agent Software, then select Open from the Actions menu. The Agent Software Updates page appears to show the Management Agent software available for different platforms.

  11. Select an update from the list of available updates. All entries other than the one that matches the platform of the OMS host should show their status as Available.

  12. Click Download. A message displays with a URL and instructions.

  13. From an Internet-enabled computer, download the file from the URL displayed in Step 12. Do one of the following:

    • Copy the file to a Management Agent host and follow the instructions displayed in Step 12.

    • Copy the file to Oracle Management Service host and follow the instructions displayed in Step 12.

    At this stage, the update will show up in a downloaded state in the Self Update home page.

  14. Once the download is complete, select the Management Agent, then click Apply. This step will stage the Management Agent software in Software Library and make it available to the Add Host Targets wizard, which you will use to install Management Agents on hosts.

Installation Procedure

To install a fresh Management Agent using the Add Host Targets Wizard, follow these steps:

  1. Ensure that the Management Agent software for the platforms of the hosts on which you want to install Management Agents is available in Software Library.

    For information on how to acquire the Management Agent software for a platform, see Meeting Management Agent Software Prerequisites.

  2. In Cloud Control, do one of the following:

    • From the Setup menu, select Add Target, then select Auto Discovery Results. On the Auto Discovery Results page, select a host you want to monitor in Enterprise Manager Cloud Control, and click Promote.

    • From the Setup menu, select Add Target, then select Add Targets Manually. On the Add Targets Manually page, select Add Host Targets and click Add Host.

  3. On the Host and Platform page, do the following:

    1. Accept the default name assigned for this session or enter a unique name of your choice. The custom name you enter can be any intuitive name, and need not necessarily be in the same format as the default name. For example, add_host_operation_1.

      Session Name

      A unique deployment activity name enables you to save the installation details specified in this deployment session and reuse them in the future without having to enter all the details all over again in the new session.

    2. Click Add to enter the fully qualified name and select the platform of the host on which you want to install the Management Agent.

      Add button to add hosts

      Note:

      • Oracle recommends you to enter the fully qualified domain name of the host. For monitoring purpose, Enterprise Manager Cloud Control adds that host and the Management Agent with the exact name you enter here.

      • You must enter only one host name per row. Entering multiple host names separated by a comma is not supported.

      • You must ensure that the host name does not contain underscores("_").

      • If the platform name is appended with Agent Software Unavailable, then it indicates that the software for that platform is not available on the OMS host, and that you must download and apply it using the Self Update console. To access the Self Update console, from the Setup menu, select Extensibility, then click Self Update.

        For more information on using the Self Update Console to download and apply the latest software, refer to Oracle Enterprise Manager Cloud Control Administrator's Guide.


      Alternatively, you can click either Load from File to add host names stored in a file, or Add Discovered Hosts to add host names from a list of hosts discovered by Enterprise Manager. For information on how the host name entries must appear in the host file, see Format of Host List File.

      Load from File and Add from Discovered Hosts Options

      Note:

      When you click Add Discovered Hosts and add hosts from a list of discovered hosts, the host's platform is automatically detected and displayed. The platform name is detected using a combination of factors, including hints received from automated discovery and the platform of the OMS host. This default platform name is a suggestion, so Oracle strongly recommends you to verify the platform details before proceeding to the next step.

      If you are correcting the platform names, and if all the hosts run on the same platform, then set the platform for the first host in the table and from the Platform list, select Same for All Hosts. This will ensure that the platform name you selected for the first host is also set for the rest of the hosts in the table.

      Platform Information

      Note:

      • If you reach this page (Host and Platform page) from the Auto Discovery Results page, then the hosts you selected on that page automatically appear in the table. In this case, you need to only validate the host names and their platforms.

      • If you are installing a Management Agent on a platform that is different from the platform on which the OMS is running, then ensure that you have the software for that platform. If you do not have that software, then go to the Self Update console within Enterprise Manager Cloud Control, download the software, then apply it. For more information, see the prerequisite about Software Availability in Table 8-1.


    3. Click Next.

  4. On the Installation Details page, do the following:

    1. In the Deployment Type section, select Fresh Agent Install.

      Install Type

      Note:

      If you have multiple hosts sharing a common mounted drive, then install the Management Agents in two different phases:
      1. In the Add Host Targets Wizard, select the deployment type Fresh Agent Install, and install a Management Agent on the host where the drive is shared.

      2. In the Add Host Targets Wizard, select the deployment type Add Host to Shared Agent, and install a Management Agent on all other hosts that access the shared, mounted drive. (Here, you will select the Management Agent you installed in the previous step as the master agent or shared agent.)


    2. From the table, select the first row that indicates the hosts grouped by their common platform name.

    3. In the Installation Details section, provide the installation details common to the hosts selected in Step 3 (b). For Installation Base Directory, enter the absolute path to the agent base directory where you want the software binaries, security files, and inventory files of the Management Agent to be copied.

      For example, /u01/app/Oracle/

      If the path you enter does not exist, the application creates a directory at the specified path, and copies the Management Agent software binaries, security files, and inventory files there.


      Note:

      The Installation Base Directory is essentially the agent base directory. Ensure that the directory you provide is empty. If a previously run deployment session had failed for some reason, then you might see an ADATMP_<timestamp> subdirectory in the agent base directory. In this case, either delete the subdirectory and start a new deployment session, or retry the failed session from the Add Host Status page.

    4. For Instance Directory, accept the default instance directory location or enter the absolute path to a directory of your choice where all Management Agent-related configuration files can be stored.

      For example, /u01/app/Oracle/agent_inst

      If you are entering a custom location, then ensure that the directory has write permission. Oracle recommends you to maintain the instance directory inside the agent base directory.

      If the path you enter does not exist, the application creates a directory at the specified path, and stores all the Management Agent-related configuration files there.

    5. From Named Credential list, select an appropriate profile whose credentials can be used for setting up the SSH connectivity between the OMS and the remote hosts, and for installing a Management Agent on each of the remote hosts.

      Named Credentials

      Note:

      • If you do not have a credential profile, or if you have one but do not see it in the Named Credential list, then click the plus icon against this list. In the Create New Named Credential window, enter the credentials and store them with an appropriate profile name so that it can be selected and used for installing the Management Agents. Also set the run privilege if you want to switch over from the Named Credential you are creating, to another user who has the privileges to perform the installation.

      • If the plus icon is disabled against this list, then you do not have the privileges to create a profile with credentials. In this case, contact your administrator and either request him/her to grant you the privileges to create a new profile or request him/her to create a profile and grant you the access to view it in the Named Credential list.

      • If you have manually set up SSH public key authentication between the OMS and the remote hosts, then you may not have a password for your user account. In this case, create a named credential with a dummy password. Do NOT leave the password field blank.


    6. For Privileged Delegation Setting, validate the Privilege Delegation setting to be used for running the root scripts. By default, it is set to the Privilege Delegation setting configured in Enterprise Manager Cloud Control.

      For example, you can specify one of the following for the Privileged Delegation Setting field:

      /usr/bin/sudo -u %RUNAS% %COMMAND%
      /usr/bin/sesu - %RUNAS% -c "%COMMAND%"
      /usr/bin/pbrun %PROFILE% -u %RUNAS% %COMMAND%
      /usr/bin/su - %RUNAS% -c "%COMMAND%"
      

      If you leave the Privileged Delegation Setting field blank, the root scripts will not be run by the wizard; you will have to run them manually after the installation. For information about running them manually, see After You Install.

      This setting will also be used for performing the installation as the user set in the Run As attribute of the selected Named Credential if you had set the user while creating that Named Credential.


      Note:

      In the Privilege Delegation setting, the %RUNAS% is honored as the root user for running the root scripts and as the user set in the Run As attribute of the Named Credential for performing the installation.

    7. For Port, accept the default port (3872) that is assigned for the Management Agent to communicate, or enter a port of your choice.

      The custom port you enter must not be busy. If you are not sure, you can leave this field blank. Enterprise Manager Cloud Control automatically assigns the first available free port within the range of 1830 - 1849.

    8. (Optional) In the Optional Details section, enter the absolute path to an accessible location where the preinstallation and postinstallation scripts you want to run are available. Note that only shell scripts are supported, and only one preinstallation or one postinstallation script can be specified.

      If you want to run the script as root, then select Run as Root. If the script is on the host where OMS is running and is not on the host where you want to install the Management Agent, then select Script on OMS. In this case, the script will be copied from the OMS host to the destination hosts, and then run on the destination hosts.

    9. (Optional) For Additional Parameters, enter a whitespace-separate list of additional parameters that you want to pass during the installation. For a complete list of supported additional parameters, see Table 8-2.

      For example, if you want to provide the inventory pointer location file, then enter -invPtrLoc followed by the absolute path to the file location. However, note that this parameter is supported only on UNIX platforms, and not on Microsoft Windows platforms.

    10. Repeat Step 3 (b) to Step 3 (i) for every other row you have in the table.

    11. Click Next.

  5. On the Review page, review the details you have provided for the installation and do one of the following:

    • If you want to modify the details, then click Back repeatedly to reach the page where you want to make the changes.

    • If you want to cancel the deployment session for some reason, click Cancel. You are automatically taken to the Add Targets Manually page.

    • If you are satisfied with the details, then click Deploy Agent to install the Management Agent. You are automatically taken to the Add Host Status page that enables you to monitor the progress of the deployment session.

      If you want to cancel a running deployment session, then on the Add Host Targets page, click Cancel. Note that once you cancel the session, you cannot track or resume the session in any way. However, the currently launched commands on the remote hosts will continue to run until they are completed.


Note:

If the installation fails for any reason, review the log files. For information on how to access the log files, refer to Oracle Enterprise Manager Cloud Control Advanced Installation and Configuration Guide.

One log file is generated per host, so if you installed Management Agents on multiple hosts, then review all the log files.


Format of Host List File

In the Add Host Targets Wizard, you can click Load from File to add the hosts listed in a file. However, ensure that the file you select has one of the following formats:

  • Only the host name.

    For Example,

    host1.example.com

    host2.example.com

  • The host name followed by the platform name.

    For Example,

    host1.example.com linux_x64

    host2.example.com aix

    The supported platform names are linux_x64, linux, solaris, hpunix, hpi, linux64_zseries, aix, linux_ppc64, windows_x64, solaris_x64, win32.

Supported Additional Parameters

Table 8-2 lists the additional parameters supported for installing a new Management Agent using the Add Host Targets Wizard.

Table 8-2 Supported Additional Parameters

Parameter Description

INVENTORY_LOCATION

Enter the absolute path to the Central Inventory (oraInventory).

For example, INVENTORY_LOCATION=$HOME/oraInventory

Note: This parameter is supported only on UNIX platforms, and not on Microsoft Windows platforms.

This parameter will be used only when the Central Inventory pointer /etc/oraInst.loc (or /var/opt/oracle/oraInst.loc) does not exist.

-invPtrLoc

Enter the absolute path to the inventory file that has the location of the Central Inventory (oraInventory).

For example, -invPtrLoc /tmp/oraInst.loc

Note: This parameter is supported only on UNIX platforms, and not on Microsoft Windows platforms.

s_agentSrvcName

(Only for Microsoft Windows) Enter a custom name for the Management Agent service.

Every Management Agent appears as a service in Microsoft Windows, and every Management Agent has a default service name. If you want to assign a custom name to identify it, then use this parameter.

For example, s_agentSrvcName=agentsrvc1

Note: If you upgrade a 12c Release 1 (12.1.0.1) Management Agent installed on a Microsoft Windows host to 12c Release 2 (12.1.0.2), and you want to install another Management Agent on the same host, reporting to a different OMS, ensure that you specify the s_agentSrvcName parameter.

b_startAgent=false

Specify this parameter if you do not want the Management Agent to start automatically once it is installed and configured.

If you do not specify this parameter, the Management Agent starts automatically once it is installed and configured.

b_secureAgent=false

Specify this parameter if you do not want the Management Agent to be secured after the install.

If you specify this parameter, ensure that you also specify the OMS HTTP port, using the EM_UPLOAD_PORT parameter.

For example, b_secureAgent=false EM_UPLOAD_PORT=4899

If you do not specify this parameter, the Management Agent is secured automatically after the install.


After You Install

After you install a Management Agent using the Add Host Targets Wizard, follow these steps:

  1. Verify the installation on the Add Host Status page. Review the progress made on each of the phases of the deployment operation — Initialization, Remote Prerequisite Check, and Agent Deployment.


    Note:

    In the Add Host Targets Wizard, after you click Deploy Agent to install one or more Management Agents, you are automatically taken to the Add Host Status page.

    If you want to view the details or track the progress of all the deployment sessions, then from the Setup menu, select Add Target, and then, click Add Targets Manually. On the Add Targets Manually page, select Add Host Targets and click Add Host Results.


    If a particular phase fails or ends up with a warning, then review the details provided for each phase in the Agent Deployment Details section, and do one of the following:

    • Ignore the warning or failure, and continue with the session if you prefer.

      • You can choose to proceed with the deployment of Management Agents only on those remote hosts that have successfully cleared the checks, and you can ignore the ones that have Warning or Failed status. To do so, click Continue and select Continue, Ignoring Failed Hosts.

      • You can choose to proceed with the deployment of Management Agents on all the hosts, including the ones that have Warning or Failed status. To do so, click Continue and select Continue, All Hosts.

    • Fix the problem by reviewing the error description carefully, understanding its cause, and taking action as recommended by Oracle.

      • You can choose to retry the deployment of Management Agents with the same installation details. To do so, click Retry and select Retry Using Same Inputs.

      • You can retry the deployment of Management Agents with modified installation details. To do so, click Retry and select Update Inputs and Retry.


    Note:

    If you want to cancel a running deployment session, then click Cancel. Note that once you cancel the session, you cannot track or resume the session in any way. However, the currently launched commands on the remote hosts will continue to run until they are completed.

  2. If required, manually verify the installation:

    1. Navigate to the Management Agent home and run the following command to see a message that confirms that the Management Agent is up and running:

      $<AGENT_INSTANCE_HOME>/bin/emctl status agent


      Note:

      If the status of the Management Agent is down for some reason, then manually start the Management Agent:

      $<AGENT_INSTANCE_HOME>/bin/emctl start agent


    2. Navigate to the Management Agent home and run the following command to see a message that confirms that EMD upload completed successfully:

      $<AGENT_INSTANCE_HOME>/bin/emctl upload

  3. Verify if all the plug-ins were installed successfully. To do so, access the following log file from the Management Agent home, and search for the sentence WARN:Plugin configuration has failed.

    $<AGENT_HOME>/cfgtoollogs/cfgfw/CfmLogger-<timestamp>.log

    For example,

    $/u01/agent/core/12.1.0.2.0/cfgtoollogs/cfgfw/CfmLogger-<timestamp>.log

    If you find the sentence, resolve the issue by running the AgentPluginDeploy.pl script from the Management Agent home.

    $<AGENT_BASE_DIR>/agent/core/12.1.0.2.0/perl/bin/perl <AGENT_BASE_DIR>/agent/core/12.1.0.2.0/bin/AgentPluginDeploy.pl -oracleHome <AGENT_BASE_DIR>/agent/core/12.1.0.2.0 -agentDir <AGENT_BASE_DIR> -pluginIdsInfoFile <AGENT_BASE_DIR>/plugins.txt -action configure -emStateDir <AGENT_INSTANCE_HOME>

    For example,

    /u01/agent/core/12.1.0.2.0/perl/bin/perl /u01/agent/core/12.1.0.2.0/bin/AgentPluginDeploy.pl -oracleHome /u01/agent/core/12.1.0.2.0/ -agentDir /u01/agent -pluginIdsInfoFile /u01/agent/plugins.txt -action configure -emStateDir /u01/agent/agent_inst

  4. If you have restrictive Privilege Delegation Provider (PDP) configuration settings, enter the location of nmosudo in your PDP configuration file.

    Enterprise Manager supports PDPs such as SUDO and PowerBroker that enable administrators to restrict certain users from running certain commands.

    In Enterprise Manager Cloud Control 12c Release 2 (12.1.0.2), nmosudo is located in the sbin directory, which is in the agent base directory. For example, <AGENT_BASE_DIRECTORY>/sbin/nmosudo. In Enterprise Manager Cloud Control 12c Release 1 (12.1.0.1) [with or without Bundle Patch 1], nmosudo is located in the agent instance directory. For example, <AGENT_INSTANCE_DIRECTORY>/bin/nmosudo.

    Therefore, when you install an Enterprise Manager Cloud Control 12c Release 2 (12.1.0.2) Management Agent, you must modify your PDP configuration file to update the new location of nmosudo.

    For example, if you use SUDO as your PDP, the configuration file for SUDO is typically /etc/sudoers. In this file, update the following entry with the new location to nmosudo.

    sudouser ALL : oracle /eminstall/basedir/sbin/nmosudo * 
    
  5. (Only for UNIX Operating Systems) If you had ignored the prerequisite check warning about not having root privileges, SUDO/PBRUN binaries, or SUDO/PBRUN privileges, then manually run the following scripts as a root user from each of the hosts where the installation was done. If you do not have SUDO/PBRUN privileges, then request your Administrator who has the privileges to run these scripts.

    • If this is the first Oracle product you just installed on the host, then run the oraInstroot.sh script from the inventory location specified in the oraInst.loc file that is available in the Management Agent home.

      For example, if the inventory location specified in the oraInst.loc file is $HOME/oraInventory, then run the following command:

      $HOME/oraInventory/oraInstRoot.sh


      Note:

      If you are not a root user, then use SUDO/PBRUN to change to a root user. For example, run the following command:

      /usr/bin/sudo $HOME/oraInventory/oraInstRoot.sh


    • Run the root.sh script from the Management Agent home:

      $<AGENT_HOME>/root.sh


      Note:

      If you are not a root user, then use SUDO/PBRUN to change to a root user. For example, run the following command:

      /usr/bin/sudo $<AGENT_HOME>/root.sh


  6. If you had ignored a prerequisite check warning about wrong time zone settings, run the following command and follow the steps it displays:

    $<AGENT_INSTANCE_HOME>/bin/emctl resetTZ agent

  7. By default, the host and the Management Agent get automatically added to the Enterprise Manager Cloud Control console for monitoring. None of the targets running on that host get automatically discovered and monitored.

    To monitor the other targets, you need to add them to Enterprise Manager Cloud Control either using the Auto Discovery Results page, the Add Targets Manually page, or the discovery wizards offered for the targets you want to monitor.

    For information about discovering targets in Enterprise Manager Cloud Control, refer to Oracle Enterprise Manager Cloud Control Administrator's Guide.


Note:

  • If Oracle Management Agents 12c Release 1 or 2 (12.1.0.x ) hang frequently or do not respond on Solaris 9ux and 10ux operating systems, then refer to document ID 1427773.1 on My Oracle Support.

  • If you want to repoint your existing Management Agents to a new Oracle Management Service (OMS), then you must first deinstall those Management Agents and plug-ins, and then redeploy those Management Agents and plug-ins using the new OMS. This is typically done when you want to move from an Enterprise Manager Cloud Control system in a test environment to an Enterprise Manager Cloud Control system in a production environment.

    When you repoint your existing Management Agents to a new OMS, you cannot move the targets monitored by the Management Agents, the target history, and the Management Agent history. The monitored targets and the history data is lost.
