Configuring for a distributed file system

Edit online

Configure IBM Storage Protect™ for ERP in a distributed file system with the following procedure.

Before you begin

For a single SID on a host, IBM Storage Protect for ERP sets the ProLE service to run with the db2SID user ID instead of root. Follow the procedure to set up the ProLE service to run with the db2SID user ID.

About this task

This set up task is not required if the following conditions exist:
  • All SAP systems are statically assigned to specific hosts. For example, the instances are not moved between hosts.
  • The root user is granted read/write access permission to the distributed file system.
If these conditions exist, the standard installation process can be used as described in the Preparing to install topic.

Procedure

  1. Enable root access to the distributed file system.
  2. Install IBM Storage Protect for ERP by using the procedure that is described in the Preparing to install topic.
  3. On a UNIX™ system, replace the following entry in the /etc/inittab file: 
    po64:345:respawn:/usr/tivoli/tsm/tdp_r3/ora64/prole -p profile
    pd64:345:respawn:/usr/tivoli/tsm/tdp_r3/db264/prole -p profile
    with this entry: 
    po64:345:respawn:su - oraSID -c /usr/tivoli/tsm/tdp_r3/ora64/prole -p profile
    pd64:345:respawn:su - db2SID -c /usr/tivoli/tsm/tdp_r3/db264/prole -p profile
    If upstart is configured, the init script /etc/init/prole_db2.conf must be used. SID must be the actual SID.
  4. Refresh the /etc/inittab processes.
  5. Disable root access to the distributed file system.

Results

For multiple SIDs on a host system, run the ProLE service by root with permanent read/write permission to the distributed file system.
