B. Preset Actions for DBMS Errors and Logged Alerts
You can remove Support for Oracle RAC from the following entities:
A cluster. See How to Remove Support for Oracle RAC From a Cluster.
Selected nodes in a cluster. See How to Remove Support for Oracle RAC From Selected Nodes.
Perform this task to remove Support for Oracle RAC from all nodes in a cluster.
On a cluster where multiple Oracle RAC databases are running, perform this task to remove an Oracle RAC database from the cluster. The remaining Oracle RAC databases continue to run in the cluster.
This task involves removing the following resource groups from the cluster in the following order:
The resource group for the Oracle RAC database
Resource groups for logical hostname resources
Resource groups for scalable file-system mount-point resources
Resource groups that contain resources for the Sun QFS metadata server
Resource groups for scalable device group resources
The Oracle RAC framework resource group
The multiple-owner volume-manager framework resource group, if used.
Caution - You might perform this task to remove an Oracle RAC database from a cluster where multiple Oracle RAC databases are running. In this situation, do not remove any resource group on whose resources the remaining Oracle RAC databases depend. For example, you might have configured multiple database file systems to depend on a single device group. In this situation, do not remove the resource group that contains the resource for the scalable device group. Similarly, if multiple databases depend on the Oracle RAC framework resource group, do not remove this resource group. |
Before You Begin
Ensure that the cluster node from which you perform this task is booted in cluster mode.
If you are using Oracle 10g release 1, omit this step. For Oracle 10g release 1, no resource groups for Oracle RAC databases are configured.
For each Oracle RAC database that you are removing, type the following command:
# clresourcegroup delete -F rac-db-rg
Specifies the resource group that you are removing.
If you are using Oracle 10g release 1, 10g release 2, 11g, or 12c, omit this step. For Oracle 10g release 1, 10g release 2, 11g, and 12c, no resource groups for logical hostname resources are configured.
For each resource group that you are removing, type the following command:
# clresourcegroup delete -F lh-rg
Specifies the resource group that you are removing.
The Oracle RAC software
The Oracle Clusterware software
If you are using Oracle 9i or Oracle 10g release 1, omit this step. For Oracle 9i and Oracle 10g release 1, no Oracle Clusterware framework resource is configured.
# clresource disable crs-framework-rs
Specifies the name of the resource that you are disabling. This resource is the instance of the SUNW.crs_framework resource type that is configured in the cluster.
If no resource groups that contain scalable file-system mount-point resources are configured, omit this step.
For each resource group that you are removing, type the following command:
# clresourcegroup delete -F scal-mp-rg
Specifies the resource group that you are removing.
If no resource groups that contain resources for the Sun QFS metadata server are configured, omit this step.
For each resource group that you are removing, type the following command:
# clresourcegroup delete -F qfs-mds-rg
Specifies the resource group that you are removing.
For instructions for performing this task, see Using SAM-QFS With Sun Cluster.
If no resource groups that contain scalable device group resources are configured, omit this step.
For each resource group that you are removing, type the following command:
# clresourcegroup delete -F scal-dg-rg
Specifies the resource group that you are removing.
How to perform this step depends on the type of the scalable device group.
Use the metaclear(1M) command for this purpose.
# metaclear -s scal-dg-ms -a
Specifies the name of the disk set from which you are removing metadevices.
# metaset -s scal-dg-ms -d -f alldevices
Specifies the name of the disk set from which you are removing global devices.
Specifies a space-separated list that contains all global devices that were added to the disk set when the disk set was created. The format of each device ID path name is /dev/did/dsk/dN, where N is the device number.
The removal of all nodes from a disk set destroys the disk set.
# metaset -s scal-dg-ms -d -h allnodes
Specifies the name of the disk set that you are destroying.
Specifies a space-separated list that contains all nodes that were added to the disk set when the disk set was created.
For more information, see your VxVM documentation.
Note - If you are removing an Oracle RAC database from a cluster where multiple Oracle RAC databases are running, omit the remaining steps in this procedure.
# clresourcegroup delete -F rac-fmwk-rg
Specifies the resource group that you are removing.
# clresourcegroup delete -F vucmm-fmwk-rg
Specifies the resource group that you are removing.
# clresourcetype unregister resource-type-list
Specifies a comma-separated list of the names of the resource types that you are unregistering. For a list of the resource types that are associated with Support for Oracle RAC, see Automatically Generated Names for Oracle Solaris Cluster Objects.
Use the uninstaller program for this purpose. For more information, see Chapter 8, Uninstalling, in Sun Java Enterprise System 5 Update 1 Installation Guide for UNIX.
Example 7-2 Removing Support for Oracle RAC From a Cluster
This example shows the sequence of operations that is required to remove Support for Oracle RAC from all nodes of a four-node cluster. The nodes in this cluster are named pclus1, pclus2, pclus3, and pclus4. Only one Oracle RAC database is configured on the cluster.
The configuration of Support for Oracle RAC in this example is as follows:
The version of Oracle RAC is 10g Release 2.
Sun QFS shared file system on Solaris Volume Manager for Sun Cluster is used to store Oracle files.
The mount points of file systems that are used for Oracle files are as follows:
Oracle database files: /db_qfs/OraData
Oracle binary files and related files: /db_qfs/OraHome
The oradg disk set is used only by the Oracle RAC database.
The name of the Oracle RAC database is swb.
The Sun QFS shared file systems use a Solaris Volume Manager for Sun Cluster multi-owner disk set that is named oradg. The creation of this disk set is shown in Example 3-1.
The configuration uses a multiple-owner volume-manager framework resource group.
The configuration of resource groups in this example is shown in the following table.
|
The resource groups that are required for this configuration are shown in Figure A-2.
To remove the resource group for the Oracle RAC database, the following command is run:
# clresourcegroup delete -F rac_server_proxy-rg
After the removal of this resource group, Oracle utilities are used to remove the following items:
The Oracle RAC database
The Oracle RAC software
The Oracle Clusterware software
The removal of these items is beyond the scope of this example.
To disable the Oracle Clusterware framework resource, the following command is run:
# clresource disable crs_framework-rs
To remove the resource group that contains scalable file-system mount-point resources, the following command is run:
# clresourcegroup delete -F scalmnt-rg
To remove the resource group that contains resources for the Sun QFS metadata server, the following command is run:
# clresourcegroup delete -F qfsmds-rg
After the removal of this resource group, Sun QFS utilities are used to remove the Sun QFS shared file systems that are used for Oracle files. The removal of these file systems is beyond the scope of this example.
To remove the resource group that contains scalable device group resources, the following command is run:
# clresourcegroup delete -F scaldg-rg
To destroy the Solaris Volume Manager for Sun Cluster multi-owner disk set oradg, the following commands are run:
# metaclear -s oradg -a # metaset -s oradg -d \ -f /dev/did/dsk/d8 /dev/did/dsk/d9 /dev/did/dsk/d15 /dev/did/dsk/d16 # metaset -s oradg -d -h pclus1 pclus2 pclus3 pclus4
The following global devices are removed from the disk set:
/dev/did/dsk/d8
/dev/did/dsk/d9
/dev/did/dsk/d15
/dev/did/dsk/d16
To remove the Oracle RAC framework resource group, the following command is run:
# clresourcegroup delete -F rac-framework-rg
To remove the multiple-owner volume-manager framework resource group, the following command is run:
# clresourcegroup delete -F vucmm-framework-rg
To unregister the resource type of each resource that was removed, the following command is run:
# clresourcetype unregister \ SUNW.scalable_rac_server_proxy,\ SUNW.ScalMountPoint,\ SUNW.qfs,\ SUNW.ScalDeviceGroup,\ SUNW.rac_svm,\ SUNW.crs_framework,\ SUNW.rac_udlm,\ SUNW.rac_framework
This configuration is running on the SPARC platform. Therefore, SUNW.rac_udlm is in the list of resource types that are unregistered.
After the unregistration of these resource types, the following operations are performed:
The removal of the Support for Oracle RAC software packages
The reboot of each node in the cluster
These operations are beyond the scope of this example.
Perform this task to remove Support for Oracle RAC from selected nodes.
On a cluster where multiple Oracle RAC databases are running, perform this task to remove an Oracle RAC database from selected nodes. The Oracle RAC database that you remove continues to run on the other cluster nodes. The remaining Oracle RAC databases continue to run on the selected nodes.
This task involves removing the selected nodes from the following resource groups in the following order:
The resource group for the Oracle RAC database
Resource groups for logical hostname resources
Resource groups for scalable file-system mount-point resources
Resource groups that contain resources for the Sun QFS metadata server
Resource groups for scalable device group resources
The Oracle RAC framework resource group
Caution - You might perform this task to remove an Oracle RAC database from selected nodes of a cluster where multiple Oracle RAC databases are running. In this situation, do not remove the nodes from any resource group on whose resources the remaining Oracle RAC databases depend. For example, you might have configured multiple database file systems to depend on a single device group. In this situation, do not remove the nodes from the resource group that contains the resource for the scalable device group. Similarly, if multiple databases depend on the Oracle RAC framework resource group, do not remove the nodes from this resource group. |
If you are using Oracle 10g release 1, omit this step. For Oracle 10g release 1, no resource groups for Oracle RAC databases are configured.
For each Oracle RAC database that you are removing, perform the following steps:
# clresourcegroup offline -n nodelist rac-db-rg
Specifies a comma-separated list of cluster nodes from which you are taking offline the resource group.
Specifies the name of the resource group that you are taking offline.
# clresourcegroup remove-node -n nodelist rac-db-rg
Specifies a comma-separated list of cluster nodes that you are removing from the resource group.
Specifies the name of the resource group from which you are removing nodes.
If you are using Oracle 10g release 1, Oracle10g release 2, 11g, or 12c, omit this step. For Oracle 10g release 1, 10g release 2, 11g, and 12c, no resource groups for logical hostname resources are configured.
For each resource group from which you are removing nodes, perform the following steps:
# clresourcegroup switch -n node-to-stay lh-rg
Specifies the node to which you are switching the resource group. This node must be a node from which you are not removing Support for Oracle RAC.
Specifies the name of the resource group that you are switching to another node.
# clresourcegroup remove-node -n nodelist lh-rg
Specifies a comma-separated list of cluster nodes that you are removing from the resource group.
Specifies the name of the resource group from which you are removing nodes.
These resource groups are no longer required because the Oracle RAC database instances that the groups serve are being removed.
Do not remove any resource groups from which you removed only secondary nodes in Step 3.
For each resource group that you are removing, type the following command:
# clresourcegroup remove -F lh-rg-rm-prim
Specifies the name of the resource group that you are removing.
If you are using Oracle 9i or Oracle 10g release 1 , omit this step. For Oracle 9i and Oracle 10g release 1, no Oracle Clusterware resources that represent Oracle Solaris Cluster resources are configured.
Note - In this step, the syntax of Oracle commands for Oracle 10g release 2, 11g, or 12c is provided. If you are using an Oracle version other than 10g release 2, 11g or 12c, see your Oracle documentation for the correct command syntax.

Example 7-3 Removing Support for Oracle RAC From Selected Nodes
This example shows the sequence of operations that is required to remove Support for Oracle RAC from nodes pclus3 and pclus4 of a four-node cluster.
The configuration of Support for Oracle RAC in this example is as follows:
The version of Oracle RAC is 10g Release 2.
Sun QFS shared file system on Solaris Volume Manager for Sun Cluster is used to store Oracle files.
The mount points of file systems that are used for Oracle files are as follows:
Oracle database files: /db_qfs/OraData
Oracle binary files and related files: /db_qfs/OraHome
The oradg disk set is used only by the Oracle RAC database.
The name of the Oracle RAC database is swb.
The Sun QFS shared file systems use a Solaris Volume Manager for Sun Cluster multi-owner disk set that is named oradg. The creation of this disk set is shown in Example 3-1.
The configuration uses a multiple-owner volume-manager framework resource group.
The configuration of resource groups in this example is shown in the following table.
|
The resource groups that are required for this configuration are shown in Figure A-2.
To remove nodes pclus3 and pclus4 from the resource group for the Oracle RAC database, the following commands are run:
# clresourcegroup offline -n pclus3,pclus4 rac_server_proxy-rg # clresourcegroup remove-node -n pclus3,pclus4 rac_server_proxy-rg
To remove nodes pclus3 and pclus4 from the node list of the Oracle Clusterware resource for the Oracle RAC database, the following commands are run:
# /db_qfs/OraHome/crs/bin/crs_register ora.swb.swb3.inst \ -update -r "ora.pclus3.vip" # /db_qfs/OraHome/crs/bin/crs_register ora.swb.swb4.inst \ -update -r "ora.pclus4.vip"
To remove from nodes pclus3 and pclus4 the Oracle Clusterware resources that represent Oracle Solaris Cluster resources, the following commands are run:
Removal of resource for Oracle database files from node plcus3 # /db_qfs/OraHome/crs/bin/crs_stop sun.pclus3.scaloramnt-OraData-rs # /db_qfs/OraHome/crs/bin/crs_unregister sun.pclus3.scaloramnt-OraData-rs # /db_qfs/OraHome/crs/bin/crs_profile -delete sun.pclus3.scaloramnt-OraData-rs \ -dir /var/cluster/ucmm/profile Removal of resource for Oracle binary files from node plcus3 # /db_qfs/OraHome/crs/bin/crs_stop sun.pclus3.scaloramnt-OraHome-rs # /db_qfs/OraHome/crs/bin/crs_unregister sun.pclus3.scaloramnt-OraHome-rs # /db_qfs/OraHome/crs/bin/crs_profile -delete sun.pclus3.scaloramnt-OraHome-rs \ -dir /var/cluster/ucmm/profile Removal of resource for Oracle database files from node plcus4 # /db_qfs/OraHome/crs/bin/crs_stop sun.pclus4.scaloramnt-OraData-rs # /db_qfs/OraHome/crs/bin/crs_unregister sun.pclus4.scaloramnt-OraData-rs # /db_qfs/OraHome/crs/bin/crs_profile -delete sun.pclus4.scaloramnt-OraData-rs \ -dir /var/cluster/ucmm/profile Removal of resource for Oracle binary files from node plcus4 # /db_qfs/OraHome/crs/bin/crs_stop sun.pclus4.scaloramnt-OraHome-rs # /db_qfs/OraHome/crs/bin/crs_unregister sun.pclus4.scaloramnt-OraHome-rs # /db_qfs/OraHome/crs/bin/crs_profile -delete sun.pclus4.scaloramnt-OraHome-rs \ -dir /var/cluster/ucmm/profile
The commands remove Oracle Clusterware resources that represent the following Oracle Solaris Cluster resources:
scaloramnt-OraData-rs – A resource of type SUNW.ScalMountPoint that represents the mount point of the file system for database files
scaloramnt-OraHome-rs – A resource of type SUNW.ScalMountPoint that represents the mount point of the file system for binary files and associated files
After the resource is removed from nodes pclus3 and pclus4, Oracle utilities are used to remove the following items from these nodes:
The Oracle RAC database
The Oracle RAC software
The Oracle Clusterware software
The removal of these items is beyond the scope of this example.
To switch the resource group that contains resources for the Sun QFS metadata server to node pclus1, the following command is run:
# clresourcegroup switch -n pclus1 qfsmds-rg
To remove nodes pclus3 and pclus4 from the resource group that contains scalable file-system mount-point resources, the following commands are run:
# clresourcegroup offline -n pclus3,pclus4 scalmnt-rg # clresourcegroup remove-node -n pclus3,pclus4 scalmnt-rg
To remove nodes pclus3 and pclus4 from the node list of the resource group that contains resources for the Sun QFS metadata server, the following command is run:
# clresourcegroup remove-node -n pclus3,pclus4 qfsmds-rg
After nodes pclus3 and pclus4 are removed from the node list, the configuration of the Sun QFS shared file systems is removed from theses nodes. This operation is beyond the scope of this example.
To remove nodes pclus3 and pclus4 from the resource group that contains scalable device group resources, the following commands are run:
# clresourcegroup offline -n pclus3,pclus4 scaldg-rg # clresourcegroup remove-node -n pclus3,pclus4 scaldg-rg
To remove nodes pclus3 and pclus4 from the Solaris Volume Manager for Sun Cluster multi-owner disk set oradg, the following command is run:
# metaset -s oradg -d -h pclus3 pclus4
To remove nodes pclus3 and pclus4 from the Oracle RAC framework resource group, the following commands are run:
# clresourcegroup offline -n pclus3,pclus4 rac-framework-rg # clresourcegroup remove-node -n pclus3,pclus4 rac-framework-rg
To remove nodes pclus3 and pclus4 from the multiple-owner volume-manager framework resource group, the following commands are run:
# clresourcegroup offline -n pclus3,pclus4 vucmm-framework-rg # clresourcegroup remove-node -n pclus3,pclus4 vucmm-framework-rg
After the removal of nodes pclus3 and pclus4 from the framework resource groups, the Support for Oracle RAC software packages can optionally be removed from the nodes.
After the removal is complete, the status of resource groups and resources is as follows:
# clresourcegroup status === Cluster Resource Groups === Group Name Node Name Suspended Status ---------- --------- --------- ------ rac-framework-rg pclus1 No Online pclus2 No Online vucmm-framework-rg pclus1 No Online pclus2 No Online scaldg-rg pclus1 No Online pclus2 No Online qfsmds-rg pclus1 No Online pclus2 No Offline scalmnt-rg pclus1 No Online pclus2 No Online rac_server_proxy-rg pclus1 No Online pclus2 No Online # clresource status === Cluster Resources === Resource Name Node Name State Status Message ------------- --------- ----- -------------- rac-framework-rs pclus1 Online Online pclus2 Online Online rac-udlm-rs pclus1 Online Online pclus2 Online Online crs_framework-rs pclus1 Online Online pclus2 Online Online vucmm-svm-rs pclus1 Online Online pclus2 Online Online scaloradg-rs pclus1 Online Online - Diskgroup online pclus2 Online Online - Diskgroup online qfs-mds-rs pclus1 Online Online - Service is online. pclus2 Offline Offline scaloramnt-OraData-rs pclus1 Online Online pclus2 Online Online scaloramnt-OraHome-rs pclus1 Online Online pclus2 Online Online rac_server_proxy-rs pclus1 Online Online - Oracle instance UP pclus2 Online Online - Oracle instance UP
