2) Checking CRS
Status:
grdoradr103:/apps/ngdbf1/oracle/nghome:actnlf_1> su –
oragrd
a) for local node
grdoradr103:/apps/grid/grdhome:+ASM3> crsctl check crs
b) for
remote nodes in the cluster
grdoradr103:/apps/grid/grdhome:+ASM3> crsctl check cluster -all
c) Viewing Cluster name:
check $CRS_HOME/cdata/<cluster_name> directory
d) Viewing
No. Of Nodes configured in Cluster:
grdoradr103:/apps/grid/grdhome:+ASM3> olsnodes -n -s
grdoradr101 1 Active
grdoradr102 2 Active
grdoradr103 3 Active
grdoradr104 4 Active
e) Check
satus of cluster resources
grdoradr103:/apps/grid/grdhome:+ASM3> crsctl stat res -t
f)
Check status of local node
cluster resources
grdoradr103:/apps/grid/grdhome:+ASM3> crsctl
stat res -t -init
g) If
any resource is down, start using the
Crsctl start
resource <resource_name>
h) Incase
of database ,instances ,services to start :
srvctl start database -d DBname
srvctl stop database -d DBname
srvctl start instance -d DBname -i INSTANCEname
srvctl stop instance -d DBname -i INSTANCEname
srvctl stop database -d DBname
srvctl start instance -d DBname -i INSTANCEname
srvctl stop instance -d DBname -i INSTANCEname
srvctl status nodeapps -n NODEname
srvctl start nodeapps -n NODEname
srvctl config database -d
DBname -> to get some information about the
database from OCR.
i)
stop clusterware stack
[root@rac1 bin]# ./crsctl stop cluster –all
j)
Stop/start all resources on local node, Need to be logged onto the
server as the root user to run this command. It will stop all HA resources on
the local node
crsctl stop crs
crsctl start crs
Note: for stoping of cluster,contact cc system team with the above command in individual servers, for stopping crs on local nodes each.ss
k) To check the Cluster version
========================
clmoraprd02:/apps/grid/grdhome:+ASM2> crsctl query crs activeversion
Oracle Clusterware active
version on the cluster is [11.2.0.3.0]
3)
To stop the CRS. -
Need to run
the below commands as root user.Since
root is the owner of the ohasd and crsd services
root 5464 1 0

---> cd
$ORA_CRS_HOME/bin
crsctl stop crs
- This command needs to be run locally on all the local hosts.
crsctl start crs
- This command needs to be run locally on all the local hosts.
4) General Troubleshooting Instructions:
when
stopping if the services does not go down.Please use the below command.
crsctl stop crs -f
- This command needs to be run locally on all the DB hosts.
After
starting/Stopping user
Crsctl check crs
on all the db hosts to find the status of crs services.
To check all the CRS resources.Please use the
below script to identify which resource is down/Up.
To check the
status of all the CRS Resources – keep it in a .sh file then Run it
============================================
#!/usr/bin/ksh
# Sample 10g CRS resource status query script
# Description:
# - Returns
formatted version of crs_stat -t, in tabular
# format, with
the complete rsc names and filtering keywords
# - The argument,
$RSC_KEY, is optional and if passed to the script, will
# limit the
output to HA resources whose names match $RSC_KEY.
# Requirements:
# - $ORA_CRS_HOME
should be set in your environment
ORA_CRS_HOME=/apps/crs/grid/product/11.2.0.3
RSC_KEY=$1
QSTAT=-u
AWK=/bin/awk #
if not available use /usr/bin/awk
# Table header:echo ""
$AWK \
'BEGIN {printf
"%-45s %-10s %-18s\n", "HA Resource", "Target",
"State";
printf "%-45s %-10s %-18s\n",
"-----------", "------", "-----";}'
# Table body:
$ORA_CRS_HOME/bin/crs_stat $QSTAT | $AWK \
'BEGIN {
FS="="; state = 0; }
$1~/NAME/
&& $2~/'$RSC_KEY'/ {appname = $2; state=1};
state == 0
{next;}
$1~/TARGET/
&& state == 1 {apptarget = $2; state=2;}
$1~/STATE/
&& state == 2 {appstate = $2; state=3;}
state == 3
{printf "%-45s %-10s %-18s\n", appname, apptarget, appstate;
state=0;}'
5) To start/stop
particular resource associated with the CRS.
===========================================================
you can get
the details of the crs resources from the above script.Based on that if any
resource is down/up we can make it up or down whatever needed using the below
commands.
crsctl start resource myResource -n server1 - To start a
particular CRS resource
crsctl stop resource myResource -n server1 - To stop a particular CRS resource.
