1. Disable clustering putting cluster_database parameter FALSE.
$export ORACLE_SID=ORCL1
$sqlplus “/ as sysdba”
Check the status of archive mode of the database:
SQL>archive log list
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 407
Current log sequence 408
SQL> alter system set cluster_database=false scope=spfile sid=’ORCL1′;
2. Shutdown all instances using srvctl utilty
$ srvctl stop database -d cobra
3. Mount tha database using one of the instance:
$ sqlplus “/ as sysdba”
SQL> startup mount
4. Enable archivelog using following command:
SQL> alter database archivelog;
5. Re-enable clustering putting instance parameter cluster_database to TRUE from the current instance:
SQL> alter system set cluster_database=true scope=spfile sid=’ORCL1′;
6. Shutdown the local instance:
SQL> shutdown immediate
7. Startup all instances using srvctl utility:
#srvctl start database -d orcl
8. If any service is not up then get up those using srvctl utility:
#srvctl start service -dorcl
9. And now check archivelog mode is enabled or not using following:
$sqlplus “/ as sysdba”
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 407
Current log sequence 408
