Oracle 23c New Features for DBA'sTo identify the clustername in Oracle CRS use
$CRS_HOME/bin/cemutlo –n
or
Use OCRDUMP
which will create a text file called OCRDUMPFILE open that file and look for this entry
#ocrdump -stdout -keyname SYSTEM | grep -A 1 clustername | grep ORATEXT | awk ‘{print $3}’
or
In the script $ORA_CRS_HOME/install/rootconfig:
ORA_CRS_HOME=/oracle/product/CRS
CRS_ORACLE_OWNER = Oracle
...
CRS_CLUSTER_NAME = crs
or
In the the $ORA_CRS_HOME/cdata,
Under cdata, there will be a directory with your clustername
or
Take an export backup of ocrfile,
#ocrconfig -export /backup/ocr_exp.dmp -s online
It will have the file created under /backup and then look for SYSTEM.css.clustername value from that file. Alternatively you can use “strings” command to read the file /backup/ocr_exp.dmp and then find out the value.
Update by a reader:-
the same can be found by using "$CRS_HOME/bin/olsnodes -c"
