How to Synchronize Primary Database Keystore with Physical Standby

How to Copy Keystore (Wallet) stored in ASM from Primary to Physical Standby

Assumptions:

It is assumed that the Keystore is already configured on Primary as well as on Standby Database
Keys in Primary Database Keystore are not synchronized with the Physical Standby Database Keystore

Step1: Create empty keystore in any other location on File system on primary
SQL> administer key management create keystore '/u01/app/Keystore/backup' identified by xxxx;

Step2:Merge both keystores, Kestore in ASM and Kestore created in file system
SQL> administer key management merge keystore '+DG_TST_DATA/TST1T/wallet' identified by xxxx into existing keystore '/u01/app/Keystore/backup' identified by xxxx with backup;
NOTE: First password is the keystore password for Keystore on ASM and second password is the keystore password for Keystore in file system

Step3:Copy the file to standby Database
Use your favorite tool eg scp or winscp and copy the merged keystore on Standby database server

Step4: Merge the Keystore into existing keystore at Physical Standby
SQL> administer key management merge keystore '/u01/app/Keystore/backup' identified by xxxx into existing keystore '+DG_TST_DATA/TST2T/wallet' identified by xxxx with backup;
NOTE: First password is the keystore password for Keystore on file system and second password is the keystore password for Keystore in ASM at Standby
Also adjust the location '/u01/app/Keystore/backup' to the location where you have copied the keystore on standby server

Step5: Bounce the standby database.

Step6: Run command to verify the key in standby server.
SQL> select * from v$encryption_wallet;
SQL> select key_id from v$encryption_keys;

Note: If the keys are not visible then follow the below steps (of course on standby database)
Step7: Close the AUTO/LOCAL AUTO LOGIN WALLET
SQL> administer key management set keystore close;

Step8: Open the Password Based Wallet

SQL> administer key management set keystore open identified by xxxx;

Step9: Verify the Keys in Password Based Wallet

SQL> select * from v$encryption_wallet;
SQL> select key_id from v$encryption_keys;

If the Keys are merged and are present in Password based wallet you need to Rebuild the AUTO/LOCAL AUTO LOGIN WALLET to synchronize it with Password based wallet

Step10: Rebuild AUTO/LOCAL AUTO LOGIN WALLET

1> backup the cwallet.sso file

ASMCMD> mv cwallet.sso cwallet.sso_bkp

2> Create the AUTO/LOCAL AUTO LOGIN WALLET from Password Based Wallet

SQL> ADMINISTER KEY MANAGEMENT CREATE LOCAL AUTO_LOGIN KEYSTORE FROM KEYSTORE '+DG_TST_DATA/TST2T/wallet' IDENTIFIED BY "xxxxxx";

3> Close the Password Based Wallet

SQL> administer key management set keystore close identified by xxxx;

4> Run command to verify the key in standby server.

SQL> select * from v$encryption_wallet;
SQL> select key_id from v$encryption_keys;

How to Switch Log File from All Instances in RAC

<<Back to Oracle RAC Main Page Switch The Log File of All Instances in Oracle RAC. In many cases you need to switch the logfile of the database. You can switch logfile using alter system switch logfile command but if you want to switch the logfile from all the instances you need to execute the command on all the instances individually and therefore you must login on all the instances. You can avoid this and switch logfile of all instances by just running the below command from any of the instance in RAC database SQL> ALTER SYSTEM SWITCH ALL LOGFILE; System altered.

Note: Oracle does not recommend deleting keystore file (ewallet.p12) that belongs to a database. If you have multiple keystores, you can choose to merge them rather than deleting either of them.
