This is a huge - 70 TB production database. When we perform database maintenance, we perform a rolling reboot - perform maintenance on a node at a time.

When we shutdown a instance, we do the following tasks:

1. stop listener -n racprod2(server)

2. nohup srvctl stop instance -d psprod -i psprod2 -o transactional &

after all process dies down

3. srvctl stop asm -n racprod2 -f

4. sudo $GRID_HOME/bin/crsctl disable crs

5.sudo $GRID_HOME/bin/crsctl stop crs -f

6. after the server comes up

Start Oracle

1. sudo $GRID_HOME/bin/crsctl start crs

2. sudo $GRID_HOME/bin/crsctl enable crs
