Verify the RAC Cluster & Database Configuration

Status of all instances and services

$ srvctl status database -d prod
Instance prod1 is running on node rac1
Instance prod2 is running on node rac2

Status of a single instance

$ srvctl status instance -d prod -i prod1
Instance prod1 is running on node rac1

Status of node applications on a particular node

$ srvctl status nodeapps -n rac1
VIP is running on node: rac1
GSD is running on node: rac1
Listener is running on node: rac1
ONS daemon is running on node: rac1

Status of an ASM instance

$ srvctl status asm -n rac1
ASM instance +ASM1 is running on node rac1

List all configured databases

$ srvctl config database

Display configuration for RAC database

$ srvctl config database -d prod
rac1 prod1 /u01/app/oracle/product/10.2.0/db_1
rac2 prod2 /u01/app/oracle/product/10.2.0/db_1

Display all services for the specified cluster database

$ srvctl config service -d prod
orcltest PREF: prod2 prod1 AVAIL:

Display the configuration for node applications – (VIP, GSD, ONS, Listener)

$ srvctl config nodeapps -n rac1 -a -g -s -l

VIP exists.: /rac1-vip/192.168.1.200/255.255.255.0/eth0:eth1
GSD exists.ONS daemon exists.
Listener exists.

Display the configuration for the ASM instance(s)

$ srvctl config asm -n rac1
+ASM1 /u01/app/oracle/product/10.2.0/db_1

Check the status of application resources.

rac1-> crs_stat -t

Check the status of Oracle Clusterware.

rac1-> crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy

rac2-> crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
Execute crsctl on the command line to check out all the available options.

List the RAC instances.

SQL> select instance_name, host_name, archiver, thread#, status from gv$instance;

Check connectivity.

Verify that you are able to connect to the instances and service on each node.

Start and Stop Oracle 10g RAC application Resources

Stop application resources
First Stop Enterprise Manager Database console ->Stop the Oracle Instance -> Down the ASM Instance -> Down the node application (Virtual IP, GSD, TNS Listener, and ONS).

$ emctl stop dbconsole$ srvctl stop instance -d prod -i prod1
$ srvctl stop instance –d prod –i prod2
$ srvctl stop asm -n rac1
$ srvctl stop asm –n rac2
$ srvctl stop nodeapps -n rac1
$srvctl stop –nodeapps –n rac2

Start application resources
First start the node applications (Virtual IP, GSD, TNS Listener, and ONS) -> Start ASM instance – >Start the Oracle instance (and related services) -> Start Enterprise Manager Database console.

$ srvctl start nodeapps -n rac1
$ srvctl start nodeapps -n rac2
$ srvctl start asm -n rac1
$ srvctl start asm -n rac2
$ srvctl start instance -d prod -i prod1
$ srvctl start instance -d prod -i prod2
$ emctl start dbconsole
