HP Serviceguard Extension for RAC (SGeRAC) manual Dependencyname

Set to yes or no depending on whether the RAC MNP is to be started on cluster join or on demand.

local_lan_failover_allowed

Set by default to yes to allow the cluster to switch LANs locally in the event of a failure.

node_fail_fast_enabled Set by default to no.

script_log_file

Set by default to "$SGRUN/log/$SG_PACKAGE.log"

TKIT_DIR

Set to the RAC MNP working directory. After the cmapplyconf command, the RAC MNP configuration file rac_dbi.conf will be created in this directory. If the rac_dbi.conf file already exists in the directory then all the configuration parameters will be overwritten, and the original rac_dbi.conf file will be backed up in rac_dbi.conf.old.

TKIT_SCRIPT_DIR

Set to the RAC MNP script files directory. The default value is the RAC MNP script files installation directory:

/opt/cmcluster/SGeRAC/toolkit/racp

ORACLE_HOME, CHECK_INTERVAL...MAINTENANCE_FLAG

These parameters can be set in the cmmakepkg command if the Toolkit configuration file is given with -t option. Otherwise set them based on the description in E-2 to fit your Oracle environment.

ORA_CRS_HOME, OC_TKIT_DIR

It is not necessary to set the values, the cmapplyconf command will automatically set them at package configuration time based on the setting in the OC MNP. Set by default to "<set by cmapplyconf>". Refer to E-2 for the descriptions.

vgchange_cmd, vg

If SLVM logical volumes are used for the Oracle RAC database storage management, in the package control file:

-set vgchange_cmd to "vgchange -a s"

-specify the name(s) of the Shared Volume Groups in vg[0], vg[1]...

cvm_activation_cmd, cvm_dg

If CVM is used for the RAC database storage management and the CVM disk group activation and deactivation are to be handled in the package control script:

-set cvm_activation_cmd to

"vxdg -g \$Disk group set activation=sharedwrite"

-specify the name(s) of the CVM Disk Groups in cvm_dg[0], cvm_dg[1]...

run_script_timeout, halt_script_timeout

Default value is 600 seconds for a 4 node cluster. This value is suggested as an initial value. It may need to be tuned for your environment.

cluster_interconnect_subnet

Set this parameter if you want to monitor the Oracle RAC interconnect network.

service_name

Set by default to racp_monitor, if multiple RAC MNPs are configured, need to set different service_name for each RAC MNP.

service_cmd

Set by default to "$SGCONF/scripts/sgerac/erac_tk_rac.sh rac_check"

service_restart

Set by default to none

service_fail_fast_enabled Set by default to no

service_halt_timeout Default value is 300

dependency_name, dependency_condition, dependency_location

Configure a dependency on the OC MNP. If CVM or CFS is used for managing the database files, and Serviceguard Disk Group (DG) MNP and Mount Point (MP) MNP are used to handle the disk group and file system mount point, add one more dependency for the corresponding DG MNP (for CVM) or MP MNP (for CFS).

For example, for the package using CVM:

DEPENDENCY_NAMEOC-MNP-name

DEPENDENCY_CONDITIONOC-MNP-PKG=UP

DEPENDENCY_LOCATIONSAME_NODE

DEPENDENCY_NAME DEPENDENCY_CONDITION DEPENDENCY_LOCATION

For the package using CFS:

DEPENDENCY_NAME

DG-MNP-name DG-MNP-PKG=UP SAME_NODE

OC-MNP-name
