Symfoware Server V12.0.0 Cluster Operation Guide

4.1 Stopping for Cluster Application Maintenance

This section describes 2 different procedures to stop for cluster application maintenance - each must be executed in maintenance state:

• Stop in maintenance state the active system and standby system cluster applications

• Stop in maintenance state only the standby system cluster application

  This means to stop in maintenance state only the standby system cluster application, while the active system cluster application remains active.

Stop in maintenance state the active system and standby system cluster applications

1. Open the [Cluster Admin] window.

2. Stop the cluster application.

   In the "rms tree view" in the [Cluster Admin] window, right-click the standby system cluster application to be stopped in maintenance state, and then select [Offline] - this stops both the active system and standby system.

3. Stop RMS.

   In the "rms tree view" in the [Cluster Admin] window, right-click the SysNode where the cluster application to be stopped in maintenance state can be found, and then select [Shutdown RMS]. Note that if you want to perform maintenance without stopping RMS, use the hvutil -d command to place the cluster application in a "Deact" state.

   Note

   • You must stop RMS if you are applying a Symfoware Server fix patch.

   • Stopping RMS also stops all cluster applications on the SysNode of the stopped RMS.

Stop in maintenance state only the standby system cluster application

In /opt/SMAW/SMAWRrms/bin/hvenv.local, add the line "export HV_RCSTART=0" (create the file if it does not yet exist).

# vi /opt/SMAW/SMAWRrms/bin/hvenv.local
Add "export HV_RCSTART=0".

1. In the "rms tree view" in the [Cluster Admin] window, right-click the standby system cluster application to be stopped in maintenance state, and then select [Offline].

2. In the "rms tree view" in the [Cluster Admin] window, right-click the SysNode where the standby system cluster application stopped in maintenance state can be found, select [Shutdown RMS], and then select [Keep local Apps] to stop RMS.

   Note

   • If the active system cluster application goes down between stopping the standby system cluster application (step 2) and stopping RMS (step 3), the stopped standby system cluster application may be used as the destination of the switch.

   • You must stop RMS if you are applying a Symfoware Server fix patch.

   • Stopping RMS also stops all cluster applications on the SysNode of the stopped RMS.
