Restore and Recover OCR from export backup (Oracle Cluster Registry)

Restore and Recover OCR from export backup (Oracle Cluster Registry) in ORACLE RAC

How to Recover OCR from EXPORT Backup?

1. verify all nodes ocr are good using below command

ocrcheck
cluvfy comp ocr -n all -verbose

2 . Take export backup of OCR from any node using root user

ocrconfig -export /tmp/ocr_cluster_backup_11112017.ocr



3. Stop the Oracle clusterware on all the nodes.

crsctl stop crs -f

4.Start the Oracle Clusterware stack on one node in exclusive mode by running the following command as root:
# crsctl start crs -excl -nocrs
The -nocrs option ensures that the crsd process and OCR do not start with the rest of the Oracle Clusterware stack.
Ignore any errors that display.
Check whether crsd is running. If it is, then stop it by running the following command as root:
# crsctl stop resource ora.crsd -init

Caution:
Do not use the -init flag with any other command.

5. If you want to restore OCR to an Oracle ASM disk group, then you must first create a disk group using SQL*Plus that has the same name as the disk group you want to restore and mount it on the local node.
start clusterware  on local node 

crsctl start crs -excl -nocrs



6. Restore the OCR backup using ocr export file loction

ocrconfig -import /tmp/ocr_cluster_backup_11112017.ocr (Import metadata of OCR using command)

7. stop clusterware 

 crsctl stop crs -f

8. Restart the Clusterware on all nodes

 Begin to start Oracle Clusterware by running the following command as root on all of the nodes:
# crsctl start crs



9. Verify OCR integrity of all of the cluster nodes that are configured as part of your cluster by running the following CVU command:

cluvfy comp ocr -n all -verbose

How to Recover Standby Database from a Missing Archive Log by applying the Incremental backup from Production Database

Data guard GAP Detection and Resolution
=============================================

How to Recover Standby Database from a Missing Archive Log by applying the Incremental backup from Production Database

Resyncing the standby data using RMAN incremental backup taken from the primary database.

Manually Resolving a Gap using incremental backup



On your physical standby database:


SQL> SELECT * FROM V$ARCHIVE_GAP;

   THREAD# LOW_SEQUENCE# HIGH_SEQUENCE#
---------- ------------- --------------
         1            32             64

SQL>


Get the current scn of the standby database.

SQL>  select current_scn from v$database;

CURRENT_SCN
-----------
    1501331

SQL>

On Primary database
******************************************

Connect to the primary database as the RMAN target and create an incremental backup from the current SCN (for a standby lagging far behind the primary):

*********************************************************************
                  Now both primary and standby database in sync mode 

*********************************************************************


==================================================================

Use the RMAN CATALOG command to register the backup sets in the RMAN repository at the duplicate. With an RMAN client connected to the standby database and the recovery catalog (if you use one at the standby), mount the standby and run the following command:

RMAN> CATALOG START WITH '/backup_location/';

The backups are now available for use in recovery of the standby.


Use the RMAN RECOVER command with the NOREDO option to apply the incremental backup to the standby database. All changed blocks captured in the incremental backup are updated at the standby database, bringing it up to date with the primary database. With an RMAN client connected to the standby database, run the following command:

RMAN> RECOVER DATABASE NOREDO;

You can now resume managed recovery at the standby. Any redo logs required at the standby with changes since those contained in the incremental are automatically requested from the primary and applied.
