Serviceguard Configuration for Oracle RAC
Using Packages to Configure Startup and Shutdown of RAC Instances
Chapter 264
• If you are using CVM, enter the names of disk groups to be activated
using the CVM_DG[] array parameters, and select the appropriate
storage activation command, CVM_ACTIVATION_CMD. Do not use the
VG[] or VXVM_DG[] parameters for CVM disk groups.
• If you are using VxVM disk groups without CVM, enter the names of
VxVM disk groups that will be imported using the VXVM_DG[] array
parameters. Enter one disk group per array element. Do not use the
CVM_DG[] or VG[] parameters for VxVM disk groups without CVM.
Also, do not specify an activation command.
• Add the names of logical volumes and file systems that will be
mounted on them.
• If you are using mirrored VxVM disks, specify the mirror recovery
option VXVOL.
• Select the appropriate options for the storage activation command
(not applicable for basic VxVM disk groups), and also include options
for mounting and unmounting filesystems, if desired.
• Specify the filesystem mount retry and unmount count options.
• Define IP subnet and IP address pairs for your package.
• Add service name(s).
• Add service command(s)
• Add a service restart parameter, if desired.
NOTE Use care in defining service run commands. Each run command is
executed by the control script in the following way:
•The cmrunserv command executes each run command and then
monitors the process id of the process created by the run command.
• When the command started by cmrunserv exits, ServiceGuard
determines that a failure has occurred and takes appropriate action,
which may include transferring the package to an adoptive node.
• If a run command is a shell script that runs some other command
and then exits, ServiceGuard will consider this normal exit as a
failure.
