Using Serviceguard Extension for RAC, 10th Edition, April 2013

You must follow the storage configuration procedures required for SLVM, CVM, CFS, ASM, or
ASM over SLVM respectively to configure the storage for Oracle Clusterware (OCR and voting
disk) and RAC database (control files, data files, redo-logs, and so on).
Certain package parameters and some specific parameter values are needed to configure the
Toolkit MNPs. In addition, some Toolkit specific configurations are needed in the Toolkit
configuration file. The following sections contain the parameters and values required by the SGeRAC
Toolkit.
The SGeRAC Toolkit for SGeRAC A.11.19 and later supports both modular and legacy package
formats.
To use the SGeRAC Toolkit in an environment running with SGeRAC and Oracle 10g R2 or later
version/revision of RAC, you must disable the automatic start feature for the Oracle Clusterware
and the RAC instances which are configured and managed in the Toolkit MNP.
Toolkit Configuration File Parameters
NOTE: SGeRAC toolkit does not support a combined configuration of modular and legacy style
SGeRAC toolkit packages. You can either configure only legacy style OC, ASMDG, and RAC
MNP or only modular style OC, ASMDG and RAC MNP .
You can test and edit the SGeRAC Toolkit configuration file /opt/cmcluster/SGeRAC/toolkit/
crsp/oc.conf (for the OC MNP), /opt/cmcluster/SGeRAC/toolkit/racp/
rac_dbi.conf (for the RAC MNP) and /opt/cmcluster/SGeRAC/toolkit/asmp/
asm_dg.conf (for the ASM MNP) before configuring the OC MNP, ASMDG MNP, and RAC
MNP.
For the OC MNP (oc.conf):
DescriptionAttributes
Oracle Clusterware home directory.ORA_CRS_HOME
The time interval in seconds (default 60) between consecutive checks of Oracle Clusterware
status by the MNP.
CHECK_INTERVAL
OC MNP maintenance mode: yes or no (default). This variable enables or disables
maintenance mode for the OC MNP. When the OC MNP MAINTENANCE_FLAG is yes,
MAINTENANCE_FLAG
the MAINTENANCE_FLAG in the RAC MNP must also be set to yes and while other values
are not suppported.
When the OC MNP needs to be maintained on one node, this parameter must be set to
yes and a file <OC MNP working directory>/oc.debug must be created manually
on that node. During this maintenance period the Oracle Clusterware process checking is
paused. Even if Oracle Clusterware is brought down on the local node, the OC MNP on
that node is not halted. When the OC MNP is in maintenance mode and the RAC MNP
maintenance mode is enabled, the corresponding RAC MNP on the same node will also
be in maintenance mode regardless of the presence of its maintenance debug file.
To continue monitoring and come back from the maintenance mode on the local node, you
must remove the oc.debug file on that node. You must ensure that the Oracle Clusterware
is properly running after the maintenance phase.
For the ASMDG MNP (asm_dg.conf):
DescriptionAttributes
Oracle Clusterware home directory.ORA_CRS_HOME
Oracle database home directory.ORACLE_HOME
HP-UX user name corresponding to the owner of Oracle software.ORACLE_USER
The home directory of Oracle where ASM is installed.ASM_HOME
