After verify that your system meets the requirements described in Chapter 1, "System Requirements", use this chapter when you prepare your system for installing Oracle Internet Directory.
Table 2-1 through Table 2-5 summarizes the requirements for installing Oracle Internet Directory on Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, Sun SPARC Solaris and Solaris Intel. If your system fails to satisfy any listed requirement, perform the tasks listed as necessary to configure your system to meet these requirements
| System Factor | Requirement for Oracle Internet Directory |
|---|---|
|
Shared Memory |
SHMMAX 0.5*(physical memory present in machine). Check your system for additional restrictions. This setting does not affect how much shared memory is needed or used by Oracle Internet Directory or the operating system. It is used only to indicate the maximum allowable size. This setting also does not impact operating system kernel resources. SHMSEG 10 |
|
Semaphores |
SEMMSL Set to 10 plus the largest PROCESSES parameter of any Oracle database on the system.
The PROCESSES parameter can be found in each SEMMNS Set to the sum of the PROCESSES parameter for each Oracle database, adding the largest one twice, then add an additional 10 for each database. See "Configure the UNIX Kernel for Oracle8i" for an example of this formula. SEMVMX 32767 |
|
Note: If any of the kernel parameters above are less than your current values, continue to use the current value. If you have other programs which use shared memory and semaphores, you will need to adjust the values accordingly. Take into account that a system reboot is necessary for kernel changes to take effect when planning for current and future database requirements. |

The following pre-installation setup tasks configure your system and set up accounts, groups, variables and permissions needed to run Oracle8i. If you do not perform these tasks prior to installation, the Installer will give the option during installation to become root and run orainstRoot.sh, a script program that will perform many of these setup tasks for you. However, running orainstRoot.sh might not provide a satisfactory environment for your system and needs. Oracle Corporation recommends that you perform these steps` manually.
Log in as the root user and perform the following tasks to set up your environment for Oracle8i:
Configure the UNIX kernel Interprocess Communication (IPC) parameters to accommodate the System Global Area (SGA) structure of Oracle8i. You will not be able to start up the database if the system does not have adequate shared memory to accommodate the SGA.
ipcs command to obtain a list of the system's current shared memory segments, semaphore segments, their identification number and owner.
Because the shared memory in AIX-Based Systems, Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, Solaris Intel, and Sun SPARC Solaris is dynamically loaded, when you run ipcs you might receive a message that the shared memory facility is not in the system. The shared memory driver loads after the Oracle8i instance is started. You can check the /etc/system file to verify that the system configured with enough shared memory.
semop call (SEMOPM)
The total allowable shared memory is determined by the formula:
SHMMAX * SHMSEG
Set SEMMNS to the sum of the PROCESSES parameter for each Oracle database, adding the largest one twice, then add an additional 10 for each database. For example, consider a system that has three Oracle instances with the PROCESSES parameter in their initsid.ora files set to the following values:
ORACLE_SID=A, PROCESSES=100 ORACLE_SID=B, PROCESSES=100 ORACLE_SID=C, PROCESSES=200
The value of SEMMNS is calculated as follows:
SEMMNS = [(A=100) + (B=100)] + [(C=200) * 2] + [(# of instances=3) * 10] = 630
Setting parameters too high for the operating system can prevent the machine from booting up. Refer to UNIX system administration documentation for parameter limits.
The following lines are examples of additions to the /etc/system file to configure the UNIX kernel with the minimum recommended values:
set shmsys:shminfo_shmmax=4294967295 set shmsys:shminfo_shmmin=1 set shmsys:shminfo_shmmni=100 set shmsys:shminfo_shmseg=10 set semsys:seminfo_semmni=100 set semsys:seminfo_semmsl=100 set semsys:seminfo_semmns=200 set semsys:seminfo_semopm=100 set semsys:seminfo_semvmx=32767
Oracle8i requires at least two mount points:
During installation, two Oracle roles are created:
Database administrators are granted these roles by virtue of their membership in corresponding UNIX groups. Oracle8i documentation refers to these UNIX groups as the osdba and osoper groups. Create the group(s) for these roles before you log in as the oracle user and start the Oracle Universal Installer. You may assign the roles to two separate UNIX groups, or to a single group.
Use the admintool or groupadd utility to create a group named dba or another name of your choosing. If you plan to assign the SYSOPER role to a separate group, create that group also.
The Oracle Universal Installer gives both Oracle SYSDBA and SYSOPER privileges to members of the UNIX group dba by default. If you perform a Custom installation of Oracle8i, or if the oracle user is not a member of a group called dba, Oracle Universal Installer will prompt you to enter the group(s) you have created for these roles.
Use the admintool or groupadd utility to create a group named oinstall. The oinstall group will own the Oracle Universal Installer's oraInventory directory. The oracle user account that runs the installation should have the oinstall group as its primary group.
The oracle account is the UNIX user account that owns the Oracle8i software after installation. Run Oracle Universal Installer with this user account.
Use the admintool or useradd utility to create an oracle account with the following properties:
Sites with multiple ORACLE_HOMEs on one system may install Oracle software with the same oracle account, or separate ones. Each oracle account must have oinstall as its primary group.
Log in to the oracle account and perform the following tasks as necessary:
Set umask to 022 for the oracle account to ensure group and other have read and execute permissions, but not write permission, on files installed.
umask command to check the current setting.
umask command does not return 022, set it in the.profile or.login file of the oracle account and execute the following command:
$ umask 022
Before starting the Oracle Universal Installer, set the DISPLAY and PATH environment variables and any of the other variables as appropriate. Table 2-7, "Environment Variable Summary", provides a brief summary of the variables listed in this section. Refer to each variable's entry in this section for instructions on setting the variable correctly.
On the system where you will run Oracle Universal Installer, set DISPLAY to the system name or IP address, X-server, and screen used by your workstation. Do not use the hostname or IP address of the system where the software is being installed unless you are performing the installation from that system's X-windows console. Use the machine name or IP of your own workstation if you are installing from a remote system. If you are not sure what the X-server and screen should be set to, use 0 (zero) for both.
If you get an Xlib error similar to "Failed to connect to server", "Connection refused by server" or "Can't open display" when starting the Installer, run the following Bourne/Korn shell or C shell commands on your X workstation:
On the server where the Oracle database will be installed, enter the following:
$ DISPLAY=workstation_name:0.0 $ export DISPLAY
In the session on your workstation:
$ xhost +server_name
On the server where the Oracle database will be installed, enter the following:
% setenv DISPLAY workstation_name:0.0
In the session on your workstation:
% xhost +server_name
If you are using a PC X server, refer to your PC X server documentation for instructions on how to configure the PC X server to allow remote X clients to connect.
Verify that the DISPLAY variable is correctly set.
Set the shell's search path to include the following:
$ORACLE_HOME/bin, /usr/bin, /etc, /usr/ccs/bin, /usr/openwin/bin
bin directory, /usr/local/bin, if it exists
ORACLE_BASE specifies the directory at the top of the Oracle software and administrative file structure. The value recommended for an OFA configuration is software_mount_point/app/oracle. For example: /u01/app/oracle. If you are not using an OFA-compliant system, Oracle recommends that you set
ORACLE_BASE.
ORACLE_HOME specifies the directory containing the Oracle software for a given release. The OFA recommended value is: $ORACLE_BASE/product/release.
For example: /u01/app/oracle/product/8.1.7.
Ensure that the value of ORACLE_HOME points to a directory that does not already contain any Oracle software prior to Oracle8i Release 1 (8.1.5) or Release 2 (8.1.6).
For Oracle Internet Directory, set NLS_LANG for the database to utf8.
Oracle supports client/server environments where clients and servers use different character sets. The character set used by a client is defined by the value of the NLS_LANG parameter for the client session. The character set used by a server is its database character set. Data conversion is done automatically between these character sets if they are different.
If you plan on creating a database during installation, you have the option of setting ORACLE_SID to the value of the Oracle server instance identifier (referred to in this installation guide as the sid). If you choose to create a database during installation, the Installer will prompt you to confirm this value.
With a text editor, add the settings for the environment variables listed in "Task 2: Set Environment Variables" to the.profile or.login file of the oracle account. Once you have finished editing these initialization files, you can quickly update the environment in the current shell session before beginning installation by using the appropriate shell command.
For the Bourne or Korn shell:
$ ../.profile
For the C shell:
% source .login
For optimal directory performance, Oracle Corporation recommends installing Oracle Internet Directory on a system separate from other Oracle software.
If Oracle8i Release 8.1.7 is not already installed on your system, then Oracle Universal Installer will install it with Oracle Internet Directory.
Complete these steps in addition to those steps listed in the chapter on preliminary tasks in Oracle Internet Directory Administrator's Guide.
If Oracle8i Release 8.1.7 is already installed on your system, verify that:
internal without a password; for example:
$ sqlplus internal
If you cannot connect as internal without a password, refer to the Oracle8i Administrator's Guide for instructions on configuring the internal account to not require a password.
$ lsnrctl status [listener_name]
The listener_name field is required if the listener has a name other than the default, listener.
