You can configure IBM® Storage Protect
Snapshot in an Oracle RAC environment so that the
IBM Storage Protect
Snapshot daemons are highly available.
When you choose this configuration, IBM Storage Protect
Snapshot remains operable even if the RAC node
that is hosting the daemons fails. The Configuration Wizard stops and starts daemons as required.
Before you begin
Ensure that a shared file system exists for the IBM Storage Protect
Snapshot repository, configuration, and binary
files. For more information about this prerequisite, see Preparing Oracle RAC.When you choose to configure IBM Storage Protect
Snapshot for Oracle RAC, the product defines
Oracle RAC node names. Each node is made available to the mount agent that is running on the backup
or clone server. The mount agent then attempts to connect to the management daemon for each node
name. When you complete the configuration and exit the Configuration Wizard,
choose to start the daemons automatically. The local node where RAC is running is configured when
the process completes.
Procedure
-
Choose Protecting a new database with the Configuration
Wizard, and step through each of the panels.
Running the Configuration Wizard configures the local node where RAC is
running, and stops and starts the daemons automatically. To ensure that the daemons are available on
all other RAC nodes, you must manually add them to /etc/inittab, or create the
upstart jobs. Alternatively, use systemd on all other RAC nodes. A locking
mechanism that uses the shared file system, ensures that only one daemon is active at a time.
The Configuration Wizard creates a link from
Oracle_instance_owner_$HOME_directory/acs to the target directory in the shared
file system on the local node where you ran the configuration. You must manually create that link on
all other RAC nodes to operate IBM Storage Protect
Snapshot
from other nodes.
-
After you configured the daemons on all RAC nodes, login as the Oracle instance owner and go to
the <Oracle_instance_owner_$HOME_directory>/acscall directory.
-
Enter the start or stop command as follows,
./setup_ora.sh -a stop -d
<Oracle_instance_owner_$HOME_directory>
or,
./setup_ora.sh -a start -d
<Oracle_instance_owner_$HOME_directory>
