Goal
Step By Step How to Recreate Dataguard Broker Configuration on Windows and Unix.
Parameters used
dg_broker_start
dg_broker_config_file1
dg_broker_config_file2
Solution
Step 1. Stop broker in both of primary and standby databases (in all instances in case of RAC):
SQL>ALTER SYSTEM SET DG_BROKER_START=FALSE;
Step 2. Drop old broker configuration files from both primary and standby:
Check the location of files using : "show parameter dg_broker_config_file"
By default the broker configuration files will be in "$ORACLE_HOME/dbs" in Unix and "$ORACLE_HOME/database" in Windows.
SQL> show parameter dg_broker_config_file
NAME TYPE VALUE
---------------------- ------ ----------------------------------------
dg_broker_config_file1 string \oracle\product\10.2.0\dbs\dr1PROD10G.dat
dg_broker_config_file2 string \oracle\product\10.2.0\dbs\dr2PROD10G.dat
Drop the files using ASMCMD if files are on ASM:
ASMCMD> cd DATA/PROD10G/
ASMCMD> rm dr1PROD10G.dat
ASMCMD> rm dr2PROD10G.dat
Windows
c:\>cd $ORACLE_HOME/database
D:\oracle\product\10.2.0\db_2\database> del dr1PROD10G.dat
D:\oracle\product\10.2.0\db_2\database> del dr2PROD10G.dat
Step 3. Start broker in both of primary and standby (in all instances in case of RAC):
SQL>ALTER SYSTEM SET DG_BROKER_START=TRUE;
Step 4. Connect to DGMGRL on primary: (from instance one in case of RAC)
$dgmgrl
DGMGRL for Linux: Version 10.2.0.3.0 - Production
Copyright (c) 2000, 2005, Oracle. All rights reserved.
Welcome to DGMGRL, type "help" for information.
DGMGRL> CONNECT sys/<password>;
Connected.
Step 5. Create configuration on primary:
DGMGRL> CREATE CONFIGURATION 'PRODCONF' AS PRIMARY DATABASE IS 'PROD10G' CONNECT IDENTIFIER IS PROD10G;
Configuration "PRODCONF" created with primary database "PROD10G"
Step 6. Add standby in the configuration:
DGMGRL> ADD DATABASE 'STDBY10G' AS CONNECT IDENTIFIER IS STDBY10G MAINTAINED AS PHYSICAL;
Current status for "PRODCONF"
SUCCESS
