11 Oracle ASM Configuration Assistant

Oracle ASM Configuration Assistant (ASMCA) supports installing and configuring Oracle ASM instances, disk groups, volumes, and Oracle Automatic Storage Management Cluster File System (Oracle ACFS). In addition, you can use the ASMCA command-line interface as a non-GUI utility.

This chapter discusses the following topics:

Oracle ASM Configuration Assistant GUI Tool

This section contains the following topics:

Starting Oracle ASM Configuration Assistant

To start ASMCA, enter asmca at a command prompt inside the Oracle Grid Infrastructure home. For example:

$ asmca

The GUI tool displays and attempts to connect to the Oracle ASM instance identified with the Oracle system identifier (SID) set to +ASM.

  • If ASMCA detects an Oracle ASM instance that is not running, then ASMCA prompts whether you want to start the instance.

  • If ASMCA detects an Oracle ASM instance from a previous release, then ASMCA prompts whether you want to upgrade the instance. Oracle recommends that you respond No this prompt.

    An Oracle ASM instance should be upgraded with Oracle Universal Installer (OUI). OUI automatically defaults to upgrade mode when it detects an Oracle ASM instance at a previous release level. See "Upgrading an Oracle ASM Instance with Oracle Universal Installer".

    To continue the upgrade process with ASMCA, see "Upgrading an Oracle ASM Instance with Oracle ASM Configuration Assistant". If you need help with upgrading an Oracle ASM instance, contact Oracle Support Services.

To start the command-line ASMCA, see "Oracle ASM Configuration Assistant Command-Line Interface".

Managing Oracle ASM Instances with Oracle ASM Configuration Assistant

Oracle ASM Configuration Assistant enables you to create an Oracle ASM instance if an Oracle ASM instance is not found on the host, as shown in Figure 11-1.

On the Create ASM page, you enter the SYS password for the administrator of the Oracle ASM instance and the password for the ASMSNMP user that can monitor this Oracle ASM instance. Note that ASMSNMP is a less privileged user that is primarily used by Oracle Enterprise Manager to monitor Oracle ASM instances.

See Also:

You can select the listener with which you want to register this Oracle ASM instance. Click ASM Parameters to update the initialization parameters for the Oracle ASM instance.

Figure 11-1 Oracle ASM Configuration Assistant Create ASM Page

Description of Figure 11-1 follows
Description of "Figure 11-1 Oracle ASM Configuration Assistant Create ASM Page"

When you can click ASM Parameters in the Create ASM page, you can update initialization parameters for an Oracle ASM instance on the Oracle ASM Configuration Assistant page, as shown in Figure 11-2.

For information about Oracle ASM instance initialization parameters, see "Configuring Initialization Parameters for Oracle ASM Instances".

Upgrading an Oracle ASM Instance with Oracle ASM Configuration Assistant

Note:

  • For information about performing an Oracle ASM Rolling Upgrade from 11.1.0.6 to 11.2.0.1, refer to Oracle Database Readme.

  • For information about upgrading Oracle ASM from version 11.2.0.1 to 11.2.0.2, see "Out of Place Upgrades".

Oracle ASM Configuration Assistant also enables you to upgrade an existing Oracle ASM instance to the current software level. However, the recommended practice is to upgrade an Oracle ASM instance with Oracle Universal Installer (OUI). OUI automatically defaults to upgrade mode when it detects an Oracle ASM instance at a previous release level. See "Upgrading an Oracle ASM Instance with Oracle Universal Installer".

The following procedure describes how to upgrade an Oracle ASM instance from 11g Release 1 (11.1) to 11g Release 2 (11.2). In this scenario:

  • The Oracle ASM and Oracle Database instances 11g Release 1 (11.1) exist in separate homes.

  • The Oracle Grid Infrastructure software 11g Release 2 (11.2) is installed in a separate home.

  • The Oracle ASM instance 11g Release 2 (11.2) is set up as an Oracle Restart (single-instance) configuration.

  1. Shut down the Oracle Enterprise Manager agent, Oracle Database instance, and the listener in the older database home.

    • Run emctl stop dbconsole to stop the Oracle Enterprise Manager agent.

    • Connect to the database instance with SQL*Plus as a privileged user and run the SHUTDOWN command.

    • Run lsnrctl and enter the STOP command to stop the listener.

    See Also:

  2. Run Oracle Universal Installer (OUI) and select the Install Oracle Grid Infrastructure Software Only option.

  3. Complete the screens in the OUI installer and run the scripts as prompted by the OUI installer.

    For example, on Linux you must run the root.sh script as the root user.

    # GRID_HOME/grid/perl/bin/root.sh
    

    When you run the root.sh script on Linux, note the instructions in the output of that script. You must run different scripts as root to configure either a standalone (single-instance) or cluster configuration after OUI has completed.

    See Also:

    Oracle Grid Infrastructure Installation Guide for information about installing Oracle Grid Infrastructure
  4. After the OUI has completed, perform the procedures that are described in the output of the root.sh script that you ran during the installation.

    For example, for a standalone (single-instance) configuration on Linux, run the following script as root to upgrade the necessary services, including Oracle Cluster Synchronization Services (CSS).

    # GRID_HOME/grid/perl/bin/perl -I/GRID_HOME/perl/lib -I/GRID_HOME/crs/install 
     GRID_HOME/crs/install/roothas.pl
    

    For an upgrade, you must update the node list by running OUI as the installation user in the Oracle Grid Infrastructure home.

    $ GRID_HOME/oui/bin/runInstaller -updateNodeList -silent -local CRS=false
      ORACLE_HOME=ASM_11G_R1_HOME
    
    $ GRID_HOME/oui/bin/runInstaller -updateNodeList -silent -local CRS=true
      ORACLE_HOME=GRID_HOME
    
  5. Ensure that the current Oracle Cluster Synchronization Services (CSS) are running in the home where the Oracle ASM instance is located. For example:

    On Linux run the crsctl check css command. If the CSS daemon is not running, run localconfig add as the root user.

    On Windows, you can use the crsctl and localconfig commands or the Windows Services GUI tool. To use Windows Services GUI tool, double-click the Services icon in the Windows Control Panel and locate the OracleCSService service. The status of OracleCSService should be Started and its startup type should be Automatic.

  6. Run the Network Configuration Assistant (NETCA) to configure the listener.

    Start Network Configuration Assistant (NETCA) in the Oracle Grid Infrastructure home with netca. Follow the prompts in the wizard to add and configure the listener in the Oracle Grid Infrastructure home.

  7. Run ASMCA from the Oracle Grid Infrastructure home to complete the upgrade.

    For information about starting ASMCA, see "Starting Oracle ASM Configuration Assistant". If the Oracle ASM instance has been shut down during the Oracle Grid Infrastructure configuration, start that instance when ASMCA prompts you to start that instance.

    When ASMCA detects an earlier version of Oracle ASM, the assistant automatically determines the location of that instance and the location of the Oracle Grid Infrastructure home, as shown in Figure 11-3.

    Enter a password for the ASMSNMP user. Note that ASMSNMP is a less privileged user that is primarily used by Oracle Enterprise Manager to monitor Oracle ASM instances.

    When you have completed the page, select Upgrade ASM to complete the upgrade. After the process has completed, you can exit from ASMCA.

    When upgrading an Oracle ASM instance to the current software level, ASMCA moves the Oracle ASM instance pre-11g Release 2 (11.2) to the Oracle Grid Infrastructure home and updates the appropriate environmental variables.

  8. Ensure that the Oracle Database instance and Oracle Enterprise Manager agent are running in the Oracle Database 11g Release 1 (11.1) home.

    Start the following services if necessary.

    • Connect to the Oracle Database instance with SQL*Plus as a privileged user and run the STARTUP command.

    • Restart the Oracle Enterprise Manager agent with emctl start dbconsole.

Note:

The procedure described in this section upgrades the Oracle ASM instance only. Oracle Database, and Oracle Enterprise Manager, will not have the latest features. To upgrade Oracle Database, see Oracle Database Upgrade Guide.

Figure 11-3 Oracle ASM Configuration Assistant Upgrade ASM Page

Description of Figure 11-3 follows
Description of "Figure 11-3 Oracle ASM Configuration Assistant Upgrade ASM Page"

After upgrading an Oracle ASM instance, you can copy or move an Oracle ASM instance. After copying or moving the SPFILE, you must restart the instance with the SPFILE in the new location to use that SPFILE. For information, see "Backing Up, Copying, and Moving an Oracle ASM Initialization Parameter File".

Figure 11-5 Oracle ASM Configuration Assistant Create Disk Groups Page

Description of Figure 11-5 follows
Description of "Figure 11-5 Oracle ASM Configuration Assistant Create Disk Groups Page"

On this page, you can enter a name for the disk group, select the redundancy level, change the disk discovery path to locate disks in a different directory, identify the disks that you want to be in the disk group, enter a name for a failure group, and specify if the failure group is a quorum type. A quorum failure group is a special type of failure group and disks in these failure groups do not contain user data and a quorum failure group is not considered when determining redundancy requirements with respect to user storage. However, a quorum failure group counts when mounting a disk group. For information about quorum failure groups, see "Oracle Cluster Registry and Voting Files in Oracle ASM Disk Groups".

The default disk group compatibility settings are 11.2 for Oracle ASM compatibility, 10.1 for database compatibility, and no value for Oracle ADVM compatibility. For information about disk group compatibility attributes, see "Disk Group Compatibility". For information about disk discovery, see "Oracle ASM Disk Discovery" and "ASM_DISKSTRING".

You can choose to show advanced options when creating a disk group, as shown in Figure 11-6. The advanced options page enables you to set additional options, such as disk group compatibility settings and allocation unit (AU) size. When you are finished with the create disk group specifications, click OK.

Note:

The disk group compatibility settings can only be advanced. You cannot revert to a lower compatibility setting after you advance the disk group compatibility settings. See "Overview of Disk Group Compatibility"
