12c Database : RAC – SRVCTL enhancements – Evaluation mode

In 12c RAC, the srvctl can be run evaluation mode , where the command tells you the impact of running that command, what actions will take place by running that command etc.

For example, modifying the server pool will show the following.

$ srvctl relocate server -servers "rac1" -eval -serverpool pool2

Database db1
     will stop on node rac1
     will start on node rac7
     Service mySrv1
          will stop on node rac1, it will not run on any node
     Service myServ2
          will stop on node rac1
          will start on node rac6
Server rac1
     will be moved from pool myPoolX to pool pool2

So you need not to worry now what would be steps you should need to perform the change

Restrictions

1. Cannot be used in administer managed databases.

2. Only the following srvctl options are possible in eval mode.

srvctl add database
srvctl add service
srvctl add srvpool
srvctl modify database
