Oracle 11g rac shutdown and startup sequence, Status view

Closing order:

1. Shut down the database. oracle users execute the srvctl command:

[Oracle @ node1 ~] $ Srvctl stop database-d ORCL --- stop instances on all nodes

[Oracle @ node1 ~] $ Srvctl status database-d devdb

Or run SQL> shutdown immediate after each node logs on to the database.

2. To stop the cluster service, you must use the root user (three steps may have been completed in step 2 ):

[Root @ node1 oracle] # cd/u01/app/11.2.0/grid/bin

[Root @ node1 bin] #./crsctl stop cluster-all ---- stop all node services

Or [root @ node1 bin] #./crsctl stop cluster ---- stop the cluster service on this node, and each node executes

You can also control the stopped nodes as follows:

[Root @ node1 bin] #./crsctl stop cluster-n rac1 rac2

View node status

[Grid @ node1 ~] $ Crs_stat-t-v or crsctl status resource-t

[Grid @ node1 ~] $ Srvctl status nodeapps

3. Stop HAS (High Availability Services ).

[Root @ node1 oracle] # cd/u01/app/11.2.0/grid/bin

[Root @ node1 bin] #./crsctl stop has-f

The preceding has startup commands must be executed on each node separately.

Startup sequence:

The RAC of 11g R2 is automatically started by default. Of course, if you need to start it manually. Manually start the instance in the order of cluster, HAS, and database. The specific command is as follows:

1. To start HAS (High Availability Services), you must use the root user

[Root @ node1 bin] #./crsctl start has

The preceding has startup commands must be executed on each node separately.

View node status

[Grid @ node1 ~] $ Crs_stat-t-v or crsctl status resource-t

2. Start the cluster)

[Root @ node1 ~] #./Crsctl start cluster-all -- all nodes start at the same time

Or only start

[Root @ node1 ~] #./Crsctl start cluster-n rac1 rac2 -- both nodes start at the same time

3. Start the database and run the srvctl command (assuming the database name is ORCL ):

[Oracle @ node1 ~] $ Srvctl start database-d ORCL --- stop instances on all nodes

Or run SQL> startup after each node logs on to the database.

Run the crs_stat command to verify the process.

Check node status

[Grid @ node1 ~] $ Crs_stat-t-v or crsctl status resource-t

[Grid @ node1 ~] $ Srvctl status nodeapps

Check database status

[Grid @ node1 ~] $ Srvctl status database-d devdb

Check ASM status

[Grid @ node1 ~] $ Srvctl status asm

Root User

Disable Automatic Start of CRS system restart

[Root @ node1 bin] #./crsctl disable crs

CRS-4621: Oracle High Availability Services autostart is disabled.

Check whether the crs is configured to start automatically

[Root @ node1 bin] #./crsctl config crs

CRS-4621: Oracle High Availability Services autostart is disabled.

Enable the CRS system to restart and automatically start (executed on each node separately)

[Root @ node1 bin] #./crsctl enable crs

CRS-4622: Oracle High Availability Services autostart is enabled.

[Root @ node1 bin] #./crsctl config crs

CRS-4622: Oracle High Availability Services autostart is enabled.

Ocr and votedisk check (grid user)

Run these commands under the grid user, crsctl query css votedisk and ocrcheck

[Grid @ node1 ~] $ Crsctl query css votedisk
