Using emctl to Create Blackout

When it comes to using EM12c, I do not like using GUI, especially in the environment I am working with.

Aside from the rant, it’s more difficult to document steps using GUI and to reproduce or automate the steps.

If you are interested in using command line, then read on.

The blackout was created at the target (monitored) server.

Determine location of Agent installation.

[oracle@arrow ~]$ ps -ef|grep agent_inst

oracle    36878  36125  0 12:56 pts/1    00:00:00 grep agent_inst
oracle   108498      1  0 Oct17 ?        00:00:22 /u01/app/oracle/product/12.1/cc_agent/core/12.1.0.3.0/perl/bin/perl
/u01/app/oracle/product/12.1/cc_agent/core/12.1.0.3.0/bin/emwd.pl
agent /u01/app/oracle/product/12.1/cc_agent/agent_inst/sysman/log/emagent.nohup

[oracle@arrow ~]$ cd /u01/app/oracle/product/12.1/cc_agent/agent_inst/bin/

Create blackout.

[oracle@arrow bin]$ ./emctl start blackout WaitUntilMonday -nodeLevel -d 3:00

Verify blackout status.

[oracle@arrow bin]$ ./emctl status blackout

Oracle Enterprise Manager Cloud Control 12c Release 3

Blackoutname = WaitUntilMonday
Targets = (arrow.local:host,)
Time = ({2015-10-23|12:57:28|180 Min,|} )
Expired = False

OOPS! Forgot to RTFM!

The blackout was created for 3 hours and not 3 days which was the intention.

The -d option is used to specify the duration of the blackout, e.g. -d 5 02:30 (5 days 2 hours and 30 minutes)
