How to create a blackout in Cloud Control using the command-line interface

Source your environment to point to the correct ORACLE_HOME. Put the following in a file called .agentenv

export ORACLE_BASE=/software/oracle
export ORACLE_HOME=/software/oracle/product/agent13c/agent_13.2
export PATH=$ORACLE_HOME/bin:$PATH
echo "\n\nOH is : $ORACLE_HOME"

If you need to create the blackout as a part of a script which needs root privileges, execute the following:

su - oracle -c ". .agent1?c;emctl start blackout  -nodeLevel -d 15;emctl stop agent"

For usage by the oracle software installation owner, skip the first part:

. .agent1?c;emctl start blackout  -nodeLevel -d 15;emctl stop agent

To stop the blackout use

. /home/oracle/.agent1?c;emctl stop blackout
