Configuring the agent for message server restart

In case the message server process fails, the Veritas High Availability agent for SAP Web Application Server supports the message server restart through SAP service (SAPSID_InstID) process sapstartsrv.exe

In case of unexpected termination, to avail the advantage of this restart technology without failing over the entire (A)SCS instance, the SAP administrator must modify the Instance profile for (A)SCS instance and set the new profile parameters.

Note:

The Veritas High Availability agent for SAP Web Application Server does not support restart of the 'enserver.exe' Enqueue server process.

To restart the message server, use the following syntax in the start profile:

Restart_Program_xx = local program name program arguments

For example, the modified syntax for the message server is as follows:

Restart_Program_02 = local $(_MS) pf=$(_PF)

By default sapstartsrv.exe restarts the message server without any delay.

For more information on how to restart the process of a program through sapstartsrv.exe, refer to SAP Note 729945 and related notes.

Note:

Veritas recommends that you carefully study the SAP note before you modify the profile files for (A)SCS instance.
