SGeRAC Toolkit Maintenance Mode
This feature allows you to perform an Oracle Clusterware and RAC database instance maintenance
job while Clusterware Multi-Node Package (OC MNP) and RAC database instance Multi-Node
packages (RAC MNP) are running in a cluster. In order to enable this feature
MAINTENANCE_FLAG should be set to “yes” in the OC MNP and RAC MNP package
configuration files and oc.debug and/or rac.debug file needs to be created under respective
Multi Node Package working directories.
NOTE: For more detailed information, see the SGeRAC Toolkit README file located in the
/opt/ cmcluster/SGeRAC/toolkit directory.
SGeRAC Toolkit
The SGeRAC Toolkit supports both legacy and modular package formats, the following new
files are created to support the modular package format:
/etc/cmcluster/modules/sgerac/erac_tk_oc
/etc/cmcluster/modules/sgerac/erac_tk_oc.1
/etc/cmcluster/modules/sgerac/erac_tk_rac
/etc/cmcluster/modules/sgerac/erac_tk_rac.1
/etc/cmcluster/scripts/sgerac/erac_tk_oc.sh
/etc/cmcluster/scripts/sgerac/erac_tk_rac.sh
/etc/cmcluster/scripts/sgerac/oc_gen.sh
/etc/cmcluster/scripts/sgerac/rac_gen.sh
NOTE: For more detailed information, see the SGeRAC Toolkit README file located in the
/opt/ cmcluster/SGeRAC/toolkit directory.
Configuration File Parameters
You need to code specific entries for all the storage groups that you want to use in an Oracle
RAC configuration. If you are using LVM, the OPS_VOLUME_GROUP parameter is included in
the cluster ASCII file. If you are using Veritas CVM, the STORAGE_GROUP parameter is included
in the package ASCII file. Details are as follows:
OPS_VOLUME_GROUP
The name of an LVM volume group whose disks are attached to at
least two nodes in the cluster; the disks will be accessed by more than
one node at a time using SLVM with concurrency control provided by
Oracle RAC. Such disks are considered cluster aware.
Volume groups listed under this parameter are marked for activation
in shared mode. The entry can contain up to 40 characters.
STORAGE_GROUP
This parameter is used for CVM disk groups. Enter the names of all
the CVM disk groups the package will use.
In the ASCII package configuration file, this parameter is called
STORAGE_GROUP.
Unlike LVM volume groups, CVM disk groups are not entered in the cluster configuration file,
they are entered in the package configuration file.
