I just stumbled across an issue introduced with Data Protector A.08.00 and the new PostgreSQL database on clustered Cell Managers running on Linux and HP-UX. It’s related to restoration of IDB configuration files back to the shared disk.
As you might know, parts of the Data Protector installation are stored on shared disk for a clustered configuration. The directory structure remains the same, but symlinks will point to the shared disk. This is true for the IDB located in /var/opt/omni/server and the configuration files stored in /etc/opt/omni/server.
[root@linux~]# ls -al /etc/opt/omni/server lrwxrwxrwx 1 root hpdp 24 May 9 14:02 /etc/opt/omni/server -> /ob2/etc_opt_omni_server
To allow the IDB integration agent postgres_bar.exe to follow the symlinks properly, you must define OB2SGENABLED=1 as an omnirc parameter on all cluster nodes that are enabled to run the Data Protector Cell Manager cluster package with Data Protector 8 and later.
Please note, if this parameter is defined, the file /opt/omni/.omnirc is not backed up as a part of the IDB backup since it is local to each node. It should be included in the regular file system backup of your cluster nodes.
