This appendix describes how to perform Oracle Clusterware and Oracle Automatic Storage Management upgrades.
Oracle Clusterware upgrades can be rolling upgrades, in which a subset of nodes are brought down and upgraded while other nodes remain active. Oracle Automatic Storage Management 11g Release 2 (11.2) upgrades can be rolling upgrades. If you upgrade a subset of nodes, then a software-only installation is performed on the existing cluster nodes that you do not select for upgrade.
This appendix contains the following topics:
Before you make any changes to the Oracle software, Oracle recommends that you create a backup of the Oracle software and databases.
Unset Oracle environment variables.
If you have set ORA_CRS_HOME as an environment variable, following instructions from Oracle Support, then unset it before starting an installation or upgrade. You should never use ORA_CRS_HOME as an environment variable except under explicit direction from Oracle Support.
Check to ensure that installation owner login shell profiles (for example,
.cshrc) do not have ORA_CRS_HOME set.
If you have had an existing installation on your system, and you are using the same user account to install this installation, then unset the following environment variables: ORA_CRS_HOME; ORACLE_HOME; ORA_NLS10; TNS_ADMIN; and any other environment variable set for the Oracle installation user that is connected with Oracle software homes.
In past releases, Oracle Automatic Storage Management (Oracle ASM) was installed as part of the Oracle Database installation. With Oracle Database 11g release 2 (11.2), Oracle ASM is installed when you install the Oracle Grid Infrastructure components and shares an Oracle home with Oracle Clusterware when installed in a cluster such as with Oracle RAC or with Oracle Restart on a standalone server.
If you have an existing Oracle ASM instance, you can either upgrade it at the time that you install Oracle Grid Infrastructure, or you can upgrade it after the installation, using Oracle ASM Configuration Assistant (ASMCA). However, be aware that a number of Oracle ASM features are disabled until you upgrade Oracle ASM, and Oracle Clusterware management of Oracle ASM does not function correctly until Oracle ASM is upgraded, because Oracle Clusterware only manages Oracle ASM when it is running in the Oracle Grid Infrastructure home. For this reason, Oracle recommends that if you do not upgrade Oracle ASM at the same time as you upgrade Oracle Clusterware, then you should upgrade Oracle ASM immediately afterward.
You can perform out-of-place upgrades to an Oracle ASM instance using Oracle ASM Configuration Assistant (ASMCA). In addition to running ASMCA using the graphic user interface, you can run ASMCA in non-interactive (silent) mode.
In prior releases, you could use Database Upgrade Assistant (DBUA) to upgrade either an Oracle Database, or Oracle ASM. That is no longer the case. You can only use DBUA to upgrade an Oracle Database instance. Use Oracle ASM Configuration Assistant (ASMCA) to upgrade Oracle ASM.
Oracle recommends that you use CVU to check if here are any patches required for upgrading your existing Oracle Grid Infrastructure 11g release 2 or Oracle RAC database 11g Release 2 installations.
To upgrade existing Oracle Clusterware installations to Oracle Grid Infrastructure 11g, your release must be greater than or equal to 10.1.0.3, 10.2.0.3, 220.127.116.11, or 11.2.
To upgrade existing Oracle Grid Infrastructure from 18.104.22.168 to 22.214.171.124 or later, you must apply patch 126.96.36.199.1 (188.8.131.52 PSU 1) or later.
To upgrade existing 11.1 Oracle Clusterware installations to Oracle Grid Infrastructure 184.108.40.206 or later, you must patch the release 11.1 Oracle Clusterware home with the patch for bug 7308467.
If you have Oracle ACFS file systems on Oracle Grid Infrastructure 11g release 2 (220.127.116.11), you upgrade Oracle Grid Infrastructure to any later version (18.104.22.168 or 22.214.171.124), and you take advantage of Redundant Interconnect Usage and add one or more additional private interfaces to the private network, then you must restart the Oracle ASM instance on each upgraded cluster member node.
Do not delete directories in the Grid home. For example, do not delete Grid_home/Opatch. If you delete the directory, then the Grid infrastructure installation owner cannot use Opatch to patch the grid home, and Opatch displays the error "checkdir error: cannot create Grid_home/OPatch'
To upgrade existing 126.96.36.199 Oracle Grid Infrastructure installations to Oracle Grid Infrastructure 188.8.131.52, you must first verify if you need to apply any mandatory patches for upgrade to succeed. Refer to "Using CVU to Validate Readiness for Oracle Clusterware Upgrades" for steps to check readiness.
See Also:"Oracle 11gR2 Upgrade Companion" Note 785351.1 on My Oracle Support:
To upgrade existing Oracle Grid Infrastructure from 184.108.40.206, to 220.127.116.11 or later, you must apply patch 18.104.22.168.1 (22.214.171.124 PSU 1) or later.
To upgrade existing 11.1 Oracle Clusterware installations to Oracle Grid Infrastructure 126.96.36.199 or later, you must patch the release 11.1 Oracle Clusterware home with the patch for bug 7308467.
Oracle Clusterware and Oracle ASM upgrades are always out-of-place upgrades. With 11g Release 2 (11.2), you cannot perform an in-place upgrade of Oracle Clusterware and Oracle ASM to existing homes.
If the existing Oracle Clusterware home is a shared home, note that you can use a non-shared home for the Oracle Grid Infrastructure for a Cluster home for Oracle Clusterware and Oracle ASM 11g Release 2 (11.2).
With Oracle Clusterware 11g release 1 and later releases, the same user that owned the Oracle Clusterware 10g software must perform the Oracle Clusterware 11g upgrade. Before Oracle Database 11g, either all Oracle software installations were owned by the Oracle user, typically
oracle, or Oracle Database software was owned by
oracle, and Oracle Clusterware software was owned by a separate user, typically
Oracle ASM and Oracle Clusterware both run in the Oracle Grid Infrastructure home.
During a major version upgrade to 11g Release 2 (11.2), the software in the 11g Release 2 (11.2) Oracle Grid Infrastructure home is not fully functional until the upgrade is completed. Running
crsctl, and other commands from the 11g Release 2 (11.2) home is not supported until the final
rootupgrade.sh script is run and the upgrade is complete across all nodes.
To manage databases in the existing earlier version (release 10.x or 11.1) database homes during the Oracle Grid Infrastructure upgrade, use the
srvctl from the existing database homes.
During Oracle Clusterware installation, if there is a single instance Oracle ASM version on the local node, then it is converted to a clustered Oracle ASM 11g Release 2 (11.2) installation, and Oracle ASM runs in the Oracle Grid Infrastructure home on all nodes.
If a single instance (non-clustered) Oracle ASM installation is on a remote node, which is a node other than the local node (the node on which the Oracle Grid Infrastructure installation is being performed), then it will remain a single instance Oracle ASM installation. However, during installation, if you select to place the Oracle Cluster Registry (OCR) and voting disk files on Oracle ASM, then a clustered Oracle ASM installation is created on all nodes in the cluster, and the single instance Oracle ASM installation on the remote node will become nonfunctional.

If you have an existing Oracle Clusterware installation, then you upgrade your existing cluster by performing an out-of-place upgrade. You cannot perform an in-place upgrade.
This section contains the following topics:
Complete the following tasks before starting an upgrade:
For each node, use Cluster Verification Utility to ensure that you have completed preinstallation steps. It can generate Fixup scripts to help you to prepare servers. In addition, the installer will help you to ensure all required prerequisites are met.
Ensure that you have information you will need during installation, including the following:
An Oracle base location for Oracle Clusterware.
An Oracle Grid Infrastructure home location that is different from your existing Oracle Clusterware location
A SCAN address
Privileged user operating system groups to grant access to Oracle ASM data files (the OSDBA for ASM group), to grant administrative privileges to the Oracle ASM instance (OSASM group), and to grant a subset of administrative privileges to the Oracle ASM instance (OSOPER for ASM group)
root user access, to run scripts as
root during installation
For the installation owner running the installation, if you have environment variables set for the existing installation, then unset the environment variables
$ORACLE_SID, as these environment variables are used during upgrade. For example:
$ unset ORACLE_BASE $ unset ORACLE_HOME $ unset ORACLE_SID
For AIX HACMP vendor clusterware on an Oracle Clusterware release 11.1 (188.8.131.52) , do the following:
When OUI prompts, do not run
Select the Install type as Upgrade and complete the upgrade. Do not run
rootupgrade.sh when prompted.
On the first node, shut down Oracle Clusterware as
rootpre.sh, ensure there are no errors, and then run
On other nodes except last one, execute step c on each node as
On the last node, execute step c sequentially as
rootupgrade.sh completes successfully on the last node, return to OUI and continue the remaining upgrade steps.
The RACcheck (Oracle RAC Configuration Audit Tool) Upgrade Readiness Assessment can be used to obtain an automated upgrade-specific health check for upgrades to Oracle Grid Infrastructure 184.108.40.206, 220.127.116.11, and 18.104.22.168. You can run the RACcheck Upgrade Readiness Assessment tool and automate many of the manual pre-upgrade and post upgrade checks.
Oracle recommends that you download and run the latest version of RACcheck from My Oracle Support. For information about downloading, configuring, and running RACcheck configuration audit tool, refer to My Oracle Support note 1457357.1, which is available at the following URL:
Review the contents in this section to validate that your cluster is ready for upgrades.
Navigate to the staging area for the upgrade, where the
runcluvfy.sh command is located, and run the command
runcluvfy.sh stage -pre crsinst -upgrade to check the readiness of your Oracle Clusterware installation for upgrades. Running
runcluvfy.sh with the
-pre crsinst -upgrade flags performs system checks to confirm if the cluster is in a correct state for upgrading from an existing clusterware installation.
The command uses the following syntax, where variable content is indicated by italics:
runcluvfy.sh stage -pre crsinst -upgrade [-n node_list] [-rolling] -src_crshome src_Gridhome -dest_crshome dest_Gridhome -dest_version dest_version [-fixup[-fixupdir path]] [-verbose]
The options are:
-n flag indicates cluster member nodes, and
nodelist the comma-delimited list of non-domain qualified node names on which you want to run a preupgrade verification. If you do not add the
-n flag to the verification command, then all the nodes in the cluster are verified. You must add the
-n flag if the clusterware is down on the node where
runcluvfy.sh is run.
Use this flag to verify readiness for rolling upgrades.
Use this flag to indicate the location of the source Oracle Clusterware or Grid home that you are upgrading, where
src_Gridhome is the path to the home that you want to upgrade.
Use this flag to indicate the location of the upgrade Grid home, where
dest_ Gridhome is the path to the Grid home.
dest_version flag to indicate the release number of the upgrade, including any patchset. The release number must include the five digits designating the release to the level of the platform-specific patch. For example: 22.214.171.124.0.
-fixup flag to indicate that you want to generate instructions for any required steps you need to complete to ensure that your cluster is ready for an upgrade. The default location is the CVU work directory. If you want to place the fixup instructions in a different directory, then add the flag
-fixupdir, and provide the path to the directory where you want to put the instructions for required fixes.
-verbose flag to produce detailed output of individual checks
You can verify that the permissions required for installing Oracle Clusterware have been configured on the nodes
node2 by running the following command:
$ ./runcluvfy.sh stage -pre crsinst -upgrade -n node1,node2 -rolling -src_crshome /u01/app/grid/126.96.36.199 -dest_crshome /u01/app/grid/188.8.131.52 -dest_version 184.108.40.206.0 -fixup -fixupdir /home/grid/fixup -verbose
Use Cluster Verification Utility to assist you with system checks in preparation for starting a database upgrade. The installer runs the appropriate CVU checks automatically, and either prompts you to fix problems, or provides a fixup script to be run on all nodes in the cluster before proceeding with the upgrade.

Use the following procedures to upgrade Oracle Clusterware or Oracle Automatic Storage Management:
Note:When you upgrade to Oracle Clusterware 11g Release 2 (11.2), Oracle Automatic Storage Management (Oracle ASM) is installed in the same home as Oracle Clusterware. In Oracle documentation, this home is called the "grid infrastructure home," or Grid home. Also note that Oracle does not support attempting to add additional nodes to a cluster during a rolling upgrade.
Use the following procedure to upgrade Oracle Clusterware from an earlier release to a later release:
Note:Oracle recommends that you leave Oracle RAC instances running. When you start the
rootupgrade.shscript on each node, that node's instances are shut down and then started up again by the script.
For standalone Oracle Databases on the cluster, only those that use Oracle ASM need to be shut down. Listeners do not need to be shut down.
Start the installer, and select the option to upgrade an existing Oracle Clusterware and Oracle ASM installation.
On the node selection page, select all nodes.
Note:In contrast with releases prior to Oracle Clusterware 11g release 2, all upgrades are rolling upgrades, even if you select all nodes for the upgrade. If you are upgrading from 220.127.116.11 to 18.104.22.168, then all nodes are selected by default. You cannot select or de-select the nodes.
Oracle recommends that you select all cluster member nodes for the upgrade, and then shut down database instances on each node before you run the upgrade
root script, starting the database instance up again on each node after the upgrade is complete. You can also use this procedure to upgrade a subset of nodes in the cluster.
Select installation options as prompted.
If you have an AIX HACMP vendor clusterware installation, then proceed to step 4.
If you do not have an HACMP cluster, then run the
rootupgrade.sh script on each node in the cluster that you want to upgrade. The script shuts down the earlier release installation, replaces it with the new Oracle Clusterware release, and starts the new Oracle Clusterware installation.After the
rootupgrade.sh script is run on a node, the upgraded Oracle Clusterware stack and AUTOSTART resources are started on the node.Run the
rootupgrade.sh script on each node on which you are performing the rolling upgrade. Run the script on the local node first. After the script completes successfully, you can run the script in parallel on all nodes except for one, which you select as the last node. When the script is run successfully on all the nodes except the last node, run the script on the last node.
If you do not have an HACMP cluster, then proceed to step 9.
If you have AIX HACMP vendor clusterware on an Oracle Clusterware cluster, then start the installer one one node in the cluster, and select the option to upgrade an existing Oracle Clusterware and Oracle ASM installation.
For the HACMP cluster, shut down the previous release Oracle Clusterware software stack on the cluster node of the cluster.
rootpre.sh script on the cluster node that you have shut down. The script shuts down the earlier release installation, replaces it with the new Oracle Clusterware release, and starts the new Oracle Clusterware installation.
rootpre.sh script is run on the node, run the Oracle Grid Infrastructure 11.2
rootupgrade.sh script. The upgraded Oracle Clusterware stack and AUTOSTART resources are started on the node.
After running the
rootupgrade.sh script on the last node in the cluster, if you left the check box with ASMCA marked, as is the default, then ASM Configuration Assistant runs automatically, and the Oracle Clusterware upgrade is complete. If you unclicked the box on the interview stage of the upgrade, then ASMCA is not run automatically.
If an earlier version of Oracle Automatic Storage Management is installed, then the installer starts ASM Configuration Assistant to upgrade Oracle ASM to 11g Release 2 (11.2). You can choose to upgrade Oracle ASM at this time, or upgrade it later.
Oracle recommends that you upgrade Oracle ASM at the same time that you upgrade the Oracle Clusterware binaries. Until ASM is upgraded, Oracle databases that use ASM can't be created. Until ASM is upgraded, the 11g Release 2 (11.2) ASM management tools in the Grid home (for example,
srvctl) will not work.
Because the Oracle Grid Infrastructure home is in a different location than the former Oracle Clusterware and Oracle ASM homes, update any scripts or applications that use utilities, libraries, or other files that reside in the Oracle Clusterware and Oracle ASM homes.
Note:At the end of the upgrade, if you set the OCR backup location manually to the older release Oracle Clusterware home (CRS home), then you must change the OCR backup location to the Oracle Grid Infrastructure home (Grid home). If you did not set the OCR backup location manually, then this issue does not concern you.
Because upgrades of Oracle Clusterware are out-of-place upgrades, the previous release Oracle Clusterware home cannot be the location of the OCR backups. Backups in the old Oracle Clusterware home could be deleted.
After you have completed the Oracle Clusterware 11g Release 2 (11.2) upgrade, if you did not choose to upgrade Oracle ASM when you upgraded Oracle Clusterware, then you can do it separately using the Oracle Automatic Storage Management Configuration Assistant (
asmca) to perform rolling upgrades.
You can use asmca to complete the upgrade separately, but you should do it soon after you upgrade Oracle Clusterware, as Oracle ASM management tools such as
srvctl will not work until Oracle ASM is upgraded.
Note:ASMCA performs a rolling upgrade only if the earlier version of Oracle ASM is either 22.214.171.124 or 126.96.36.199. Otherwise, ASMCA performs a normal upgrade, in which ASMCA brings down all Oracle ASM instances on all nodes of the cluster, and then brings them all up in the new Grid home.
Note the following if you intend to perform rolling upgrades of Oracle ASM:
$ crsctl query crs activeversion
You can upgrade a standalone Oracle ASM installation to a clustered Oracle ASM installation. However, you can only upgrade an existing standalone Oracle ASM installation if you run the installation from the node on which the Oracle ASM installation is installed. You cannot upgrade a single instance Oracle ASM installation on a remote node.
You must ensure that any rebalance operations on your existing Oracle ASM installation are completed before starting the upgrade process.
During the upgrade process, you alter the Oracle ASM instances to an upgrade state. Because this upgrade state limits Oracle ASM operations, you should complete the upgrade process soon after you begin. The following are the operations allowed when an Oracle ASM instance is in the upgrade state:
Diskgroup mounts and dismounts
Opening, closing, resizing, or deleting database files
Queries of fixed views and packages: Users are allowed to query fixed views and run anonymous PL/SQL blocks using fixed packages, such as
Complete the following procedure to upgrade Oracle ASM:
On the node you plan to start the upgrade, set the environment variable ASMCA_ROLLING_UPGRADE as true. For example:
$ export ASMCA_ROLLING_UPGRADE=true
From the Oracle Grid Infrastructure 11g Release 2 (11.2) home, start ASMCA. For example:
$ cd /u01/11.2/grid/bin $ ./asmca
ASM Configuration Assistant upgrades Oracle ASM in succession for all nodes in the cluster.
After you complete the upgrade, run the command to unset the ASMCA_ROLLING_UPGRADE environment variable.
Because Oracle Clusterware release 2 (11.2) is an out-of-place upgrade of the Oracle Clusterware home in a new location (the Oracle Grid Infrastructure for a cluster home, or Grid home), the path for the CRS_HOME parameter in some parameter files must be changed. If you do not change the parameter, then you encounter errors such as "cluster target broken on dbcontrol or Grid control.
Use the following procedure to resolve this issue:
Log in to
Navigate to the Cluster tab.
Click Monitoring Configuration
Update the value for Oracle Home with the new Grid home path.
After upgrade from previous releases, if you want to deinstall the previous release Oracle Grid Infrastructure Grid home, then you must first change the permission and ownership of the previous release Grid home. Log in as root, and change the permission and ownership of the previous release Grid home using the following command syntax, where oldGH is the previous release Grid home, swowner is the Oracle Grid Infrastructure installation owner, and oldGHParent is the parent directory of the previous release Grid home:
#chmod -R 755 /u01/app/188.8.131.52/grid #chown -R grid /u01/app/184.108.40.206/grid #chown grid /u01/app/220.127.116.11
After a successful or a failed upgrade to Oracle Clusterware 11g Release 2 (11.2), you can restore Oracle Clusterware to the previous version.
The restoration procedure in this section restores the Clusterware configuration to the state it was in before the Oracle Clusterware 11g Release 2 (11.2) upgrade. Any configuration changes you performed during or after the 11g Release 2 (11.2) upgrade are removed and cannot be recovered.
In the following procedure, the local node is the first node on which the rootupgrade script was run. The remote nodes are all other nodes that were upgraded.
To restore Oracle Clusterware to the previous release:
Use the downgrade procedure for the release to which you want to downgrade.
Downgrading to releases prior to 11g release 2 (18.104.22.168):
On all remote nodes, use the command syntax Grid_home
/perl/bin/perl/ rootcrs.pl -downgrade [-force] to stop the 11g Release 2 (11.2) resources, shut down the 11g Release 2 (11.2) stack.
Note:This command does not reset the OCR, or delete
Command syntax is as follows:
# /u01/app/11.2.0/grid/perl/bin/perl rootcrs.pl -downgrade -oldcrshome -version
# /u01/app/11.2.0/grid/perl/bin/perl rootcrs.pl -downgrade -oldcrshome /u01/app/crs -version 22.214.171.124.0
Note:Ensure that Oracle Clusterware version is specified in the correct format. For example, 126.96.36.199.0.
If you want to stop a partial or failed 11g Release 2 (11.2) installation and restore the previous release Oracle Clusterware, then use the
-force flag with this command.
Downgrading to a release 188.8.131.52 or later release:
Use the command syntax /rootcrs.pl -downgrade -oldcrshome oldGridHomePath -version oldGridversion, where oldGridhomepath is the path to the previous release Oracle Grid Infrastructure home, and oldGridversion is the release to which you want to downgrade. For example:
/rootcrs.pl -downgrade -oldcrshome /u01/app/11.2.0/grid -version 184.108.40.206
If you want to stop a partial or failed 11g release 2 (11.2) installation and restore the previous release Oracle Clusterware, then use the -force flag with this command.
rootcrs.pl -downgrade script has completed on all remote nodes, on the local node use the command syntax Grid_home/crs/install/rootcrs.pl -downgrade -lastnode -oldcrshome pre11.2_crs_home -version pre11.2_crs_version [-force], where pre11.2_crs_home is the home of the earlier Oracle Clusterware installation, and pre11.2_crs_version is the release number of the earlier Oracle Clusterware installation.
# /u01/app/11.2.0/grid/crs/install/rootcrs.pl -downgrade -lastnode -oldcrshome /u01/app/crs -version 220.127.116.11.0
This script downgrades the OCR. If you want to stop a partial or failed 11g Release 2 (11.2) installation and restore the previous release Oracle Clusterware, then use the
-force flag with this command.
Log in as the Grid infrastructure installation owner, and run the following commands, where
/u01/app/grid is the location of the new (upgraded) Grid home (11.2):
.Grid_home/oui/bin/runInstaller -nowait -waitforcompletion -ignoreSysPrereqs -updateNodeList -silent CRS=false ORACLE_HOME=/u01/app/grid
As the Grid infrastructure installation owner, run the command ./runInstaller -nowait -waitforcompletion -ignoreSysPrereqs -updateNodeList -silent CRS=true ORACLE_HOME=pre11.2_crs_home, where pre11.2_crs_home represents the home directory of the earlier Oracle Clusterware installation.
.Grid_home/oui/bin/runInstaller -nowait -waitforcompletion -ignoreSysPrereqs -updateNodeList -silent CRS=true ORACLE_HOME=/u01/app/crs
For downgrades to 11.2 and later releases
If you are downgrading from Oracle Grid Infrastructure release 2 (18.104.22.168) to an earlier release of 11.2, after execution of
rootupgrade.sh is completed on all cluster nodes, run the following command from the 22.214.171.124 Grid home:
From the earlier release Grid home, run the following command as a privileged user (
On each node, start Oracle Clusterware from the earlier release Oracle Clusterware home using the command
crsctl start crs. For example, where the earlier release home is
crshome11202, use the following command on each node:
crshome11202/bin/crsctl start crs
For downgrades to 11.1 and earlier releases
You are prompted to run
root.sh from the earlier release Oracle Clusterware installation home in sequence on each member node of the cluster. After you complete this task, downgrade is completed.
root.sh from the earlier release Oracle Clusterware installation home restarts the Oracle Clusterware stack, starts up all the resources previously registered with Oracle Clusterware in the older version, and configures the old initialization scripts to run the earlier release Oracle Clusterware stack.
Change the following environment variables to point to the directories of the release to which you are downgrading:
Ensure that your
oratab file and any client scripts that set the value of
ORACLE_HOME point to the downgraded Oracle home.
If you are upgrading from a prior release using IPD/OS to Oracle Grid Infrastructure release 2 (126.96.36.199 and later), then you should review the Cluster Health Monitor repository size (the CHM repository). Oracle recommends that you review your CHM repository needs, and enlarge the repository size if you want to maintain a larger CHM repository.
Note:Your previous IPD/OS repository is deleted when you install Oracle Grid Infrastructure, and you run the
root.shscript on each node.
By default, the CHM repository size for release 188.8.131.52 and later is a minimum of either 1GB or 3600 seconds (1 hour).
To enlarge the CHM repository, use the following command syntax, where RETENTION_TIME is the size of CHM repository in number of seconds:
oclumon manage -repos resize RETENTION_TIME
The value for RETENTION_TIME must be more than
3600 (one hour) and less than
259200 (three days). If you enlarge the CHM repository size, then you must ensure that there is local space available for the repository size you select on each node of the cluster. If there is not sufficient space available, then you can move the repository to shared storage.
For example, to set the repository size to four hours:
$ oclumon manage -repos resize 14400
