Verifying the configuration

After editing the main.cf file for you configuration, check the configuration.

 To check the configuration

1. Verify the syntax of the file /etc/VRTSvcs/conf/config/main.cf:

   # cd /etc/VRTSvcs/conf/config

   # hacf -verify .

2. Start the VCS engine on System A:

   # hastart

3. Type the hastatus command:

   # hastatus

4. When "LOCAL_BUILD" is listed in the message column, start VCS on System B:

   # hastart

5. Verify that all DB2 UDB service group resources are brought online on System A:

   # hagrp -display

6. Take the service groups offline on System A and verify that all resources are stopped:

   # hagrp -offline db2udb_grp1 -sys sysa

   # hagrp -offline db2udb_grp3 -sys sysa

   # hagrp -display

7. Bring the service groups online again on System A and verify that all resources are available:

   # hagrp -online db2udb_grp1 -sys sysa

   # hagrp -online db2udb_grp3 -sys sysa

   # hagrp -display

8. Switch the DB2 UDB service group to System B:

   # hagrp -switch db2udb_grp1 -to sysb

   # hagrp -switch db2udb_grp3 -to sysb

9. Verify that all DB2 UDB service group resources are brought online on System B:

   # hagrp -display

    /var/VRTSvcs/log/engine_A.log

    /var/VRTSvcs/log/Db2udb_A.log
