START / STOP CLUSTERWARE CRS:

================================
1. START / STOP CLUSTERWARE CRS:
================================
To start and stop CRS when the machine starts or shutdown, on unix there are rc scripts in place.
/etc/init.d/init.crs start
/etc/init.d/init.crs stop
/etc/init.d/init.crs enable
/etc/init.d/init.crs disable
You can also, as root, manually start, stop, enable or disable the services with:
# crsctl start crs
# crsctl stop crs
# crsctl enable crs
# crsctl disable crs
On a unix system, you may find the following in the /etc/inittab file.
# cat /etc/inittab | grep crs
h3:35:respawn:/etc/init.d/init.crsd run > /dev/null 2>&1
/dev/null 2>&1 /dev/null 2>&1 ls -al *init* init.crs init.crsd init.cssd init.evmd #
cat /etc/inittab .. .. h1:35:respawn:/etc/init.d/init.evmd
run > /dev/null 2>&1 /dev/null 2>&1 /dev/null 2>&1

aix2 /home/oracle--> SRVCTL
example: ---------------
$ srvctl status nodeapps -n mynewserver
VIP is running on node:
mynewserver GSD is running on node:
mynewserver Listener is not running on node
: mynewserver ONS daemon is running on node:
mynewserver CRSCTL
example: --------------- Checking crs on the node:
# crsctl check crs Cluster Synchronization Services appears healthy Cluster Ready Services appears healthy Event Manager appears healthy
Checking crs clusterwide: crsctl check cluster
# crsctl check cluster node1-pub ONLINE
node2-pub ONLINE ===================
4. OTHER EXAMPLES: ===================
Example 1. Bring up the MYSID1 instance of the MYSID database.
$ srvctl start instance -d MYSID -i MYSID1
Example 2. Stop the MYSID database: all its instances and all its services, on all nodes.
$ srvctl stop database -d MYSID Example
3. Stop the nodeapps on the myserver node. NB: Instances and services also stop.
$ srvctl stop nodeapps -n myserver Example
4. Add the MYSID3 instance, which runs on the myserver node, to the MYSID clustered database.
$ srvctl add instance -d MYSID -i MYSID3 -n myserver Example 4. Add a new node, the mynewserver node, to a cluster.
$ srvctl add nodeapps -n mynewserver -o
$ORACLE_HOME -A 10.10.10.100/255.255.255.0/eth1 (The -A flag precedes an address specification.)
Example 5. To change the VIP (virtual IP) on a RAC node, use the command $ srvctl modify nodeapps -A new_address Example
6. Disable the ASM instance on myserver for maintenance.
$ srvctl disable asm -n myserver Some other examples: --------------------
$ srvctl add instance -d -i -n $ srvctl add service -d -s -r “” [-a ""] [-P ] $ srvctl add service -d -s -u {-r “” | -a “”}

$ srvctl add asm -n -i -o [-p ]
$ srvctl config database $ srvctl config database -d [-a] [-t]
$ srvctl config service -d [-s ] [-a] [-S ]
