SRVCTL is known as server control utility, which is used to add,
remove,relocate and manage different crs services or components
in RAC database.
1. STOP DATABASE :
SYNTAX – srvctl stop database -d
db_name [-o stop_options] where stop_options is
normal/immediate(default)/transactional/abort
e.g
srvctl stop database -d PRODB -o normal srvctl stop database -d
PRODB -o immediate srvctl stop database -d PRODB -o transactional
srvctl stop database -d PRODB -o abort
2. START DATABASE
SYNTAX – srvctl start database -d
db_name [-o start_options] where sta
rt_option is nomount/mount/open(default)
e.g
srvctl start database -d PRODB -o nomount srvctl start database -d
PRODB -o mount srvctl start database -d PRODB -o open
3. STOP AN INSTANCE
SYNTAX –
srvctl stop instance -d
db_unique_name [-i “instance_name_list”]} [-o stop_options]
[-f]
e.g
srvctl stop instance -d PRODB -i PRODB1
4. START AN INSTANCE
SYNTAX –
srvctl start instance -d db_unique_name [-i
“instance_name_list”} [-o start_options]
e.g
srvctl start instance -d PRODB -i PRODB1
5. REMOVING DB FROM CRS:
SYNTAX –
srvctl remove database -d
db_unique_name [-f] [-y] [-v]
e.g
srvctl remove database -d PRODB -f -y
6. ADDING DB IN CRS :
SYNTAX –
srvctl add database -d
db_unique_name -o ORACLE_HOME [-p spfile]
e.g
srvctl add database -d PRODB -o
/u01/app/oracle/product/12.1.0.2/dbhome_1 -p
+DATA/PRODDB/parameterfile/spfilePRODB.ora
7. REMOVING AN INSTANCE FROM CRS:
SYNTAX –
srvctl remove instance -d
DB_UNIQUE_NAME -i INSTANCE_NAME
e.g
srvctl remove instance -d PRODB - I PRODB1
8.ADDING AN INSTANCE TO CRS:
SYNTAX –
srvctl add instance –d
db_unique_name –i inst_name -n node_name
e.g
srvctl add instance -d PRODB - i PRODB1 -n rachost1
9. Enable/disable auto restart of the instance
srvctl enable instance -d DB_UNIQUE_NAME-i INSTANCE_NAME srvctl
disable instance -d DB_UNIQUE_NAME-i INSTANCE_NAME
10. Enable/disable auto restart of the database
srvctl enable database -d DB_UNIQUE_NAME srvctl disable database -d
DB_UNIQUE_NAME
11. ADDING A SERVICE:
SYNTAX –
srvctl add servicec -d
{DB_NAME} -s {SERVICE_NAME} -r {“preferred_list”} -a
{“available_list”} [-P {BASIC | NONE |
PRECONNECT}]
e.g
srvctl add service -d PREDB -s PRDB_SRV -r 'PREDB1,PREDB2' -a
'PREDB2' -P BASIC
12.REMOVING A SERVICE:
SYNTAX –
srvctl remove service -d
{DB_NAME} -s {SERVICE_NAME}
e.g
srvctl remove service -d PREDB -s PRDB_SRV
13. START A SERVICE
SYNTAX–
srvctl start servicec -d {DB_NAME}
-s {SERVICE_NAME}
e.g
srvctl start service -d PREDB -s PRDB_SRV
14. STOP A SERVICE
SYNTAX–
srvctl stop servicec -d {DB_NAME}
-s {SERVICE_NAME}
e.g
srvctl stop service -d PREDB -s PRDB_SRV
15. RELOCATE A SERVICE
SYNTAX –
srvctl relocate service -d
{database_name} -s {service_name} -i {old_inst_name} -r
{new_inst_name}
EXAMPLE: (Relocating service PRDB_SRV from PREDB2 to PREDB1)
srvctl relocate service -d PREDB -s PRDB_SVC -i PREDB2 -t
PREDB1
16. Check the status of service
SYNTAX –
srvctl status service -d
{database_name} -s {service_name}
srvctl status service -d PREDB -s PRDB_SVC
17. Check the configuration of service
SYNTAX –
srvctl config service -d
{database_name} -s
{service_name}
srvctl config service -d PREDB -s PRDB_SVC
18. Check scan listener configuration
srvctl config scan_listener SCAN Listener LISTENER_SCAN1 exists.
Port: TCP:1522 Registration invited nodes: Registration invited
subnets: SCAN Listener is enabled. SCAN Listener is individually
enabled on nodes: SCAN Listener is individually disabled on nodes:
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1522 Registration
invited nodes: Registration invited subnets: SCAN Listener is
enabled. SCAN Listener is individually enabled on nodes: SCAN
Listener is individually disabled on nodes: SCAN Listener
LISTENER_SCAN3 exists. Port: TCP:1522 Registration invited nodes:
Registration invited subnets: SCAN Listener is enabled. SCAN
Listener is individually enabled on nodes: SCAN Listener is
individually disabled on nodes:
19. Modify scan_listener port:
srvctl modify scan_listener -p {new-SCAN-port} srvctl modify
scan_listener -p 1523 $GRID_HOME/bin/srvctl stop scan_listener
$GRID_HOME/bin/srvctl start scan_listener Alter system set
remote_listener='orcl-scan.stc.com.sa:1523' scope=both
sid='*';
20. Manage MGMTDB in oracle 12c:
srvctl status mgmtdb Database is enabled Instance -MGMTDB is
running on node node12-1 -- stop and start MGMT db. srvctl stop
mgmtdb srvctl start mgmtdb
21. Enable trace for srvctl commands:
-- set this to enable trace at os SRVM_TRACE=true export SRVM_TRACE
-- run any srvctl command srvctl status database -d ORACL
22. Set environment variables through srvctl.
-- setenv to set env variables.(ORCL is the db_unique_name) srvctl
setenv database -db ORCL -env
'ORACLE_HOME=/oracle/app/oracle/product/12.1.0.2/dbhome_1' srvctl
setenv database -db ORCL -env
'TNS_ADMIN=/oracle/app/oracle/product/12.1.0.2/dbhome_1/network/admin'
--getenv to view the env setting: srvctl getenv database -db ORCL
ORCL: ORACLE_HOME=/oracle/app/oracle/product/12.1.0.2/dbhome_1
TNS_ADMIN=/oracle/app/oracle/product/12.1.0.2/dbhome_1/network/admin
23. Check status and config of ASM instance:
srvctl config asm ASM home: Password file: +MGMT/orapwASM ASM
listener: LISTENER srvctl status asm ASM is running on
ses11-4,ses11-5
24. Stop and start services running from
ORACLE_HOME
srvctl stop home -oraclehome /oracle/product/12.1.0.2/dbhome_1
-statefile /home/oracle/state.txt -node dbhost-1 srvctl start home
-oraclehome /oracle/product/12.1.0.2/dbhome_1 -statefile
/home/oracle/state.txt -node dbhost-1
25. Create a TAF policy
srvctl add service -db ORCLDB -service TAF_ORCL -preferred ORCLDB1
-available ORCLDB2 -tafpolicy BASIC -failovertype SELECT srvctl
start service -db OMPREDB -service TAF_ORCL
