How to Configure Oracle Dataguard Broker

Make sure these parameters properly set on primary/standby database.

standby_file_management=AUTO
fal_client=Host DB name
fal_server=Remote DB name
local_listener=Host Listener name
remote_listener=Remote Listener name
standby_archive_dest=archive destination on standby database
db_unique_name=should be different for primary and standby
log_file_name_convert=‘primary destination’,’standby destination’
RAC services should be created using db_unique_name

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; 
Make sure log_file_convert is properly set on standby database.

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 

Drop the files using : 

Unix 
$cd $ORACLE_HOME/dbs 
$ rm dr1PROD10G.dat 
$ 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 

ALTER SYSTEM SET dg_broker_config_file1=’+ORAUMARKET_DATA3/dr1mgf.dat’ scope=both sid=’*’;
ALTER SYSTEM SET dg_broker_config_file2=’+ORAUMARKET_DATA3/dr2mgf.dat’ scope=both sid=’*’;

It should be on shared location in case of RAC.

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/; 
Connected. 

Step 5. Create configuration on primary: 
DGMGRL> CREATE CONFIGURATION 'DGCONFIG_PROD' AS PRIMARY DATABASE IS 'UMARKET' CONNECT IDENTIFIER IS UMARKET; 
Configuration "PRODCONF" created with primary database "PROD10G" 

Step 6. Add standby in the configuration: 
DGMGRL> ADD DATABASE 'UMARKET_DR' AS CONNECT IDENTIFIER IS UMARKET_DR MAINTAINED AS PHYSICAL; 
Database "STDBY10G" added

Step 7.
DGMGRL> show configuration
Configuration
  Name:                DGCONFIG_PROD
  Enabled:             YES
  Protection Mode:     MaxPerformance
  Fast-Start Failover: DISABLED
  Databases:
    UMARKET    - Physical standby database
    UMARKET_DR - Primary database
Current status for "DGCONFIG_PROD":
SUCCESS

Step 8. Enable Configuration: 
DGMGRL> ENABLE CONFIGURATION; 
Enabled. 

Use the SHOW command to verify that the configuration and its databases were successfully enabled and brought online: 
DGMGRL> SHOW CONFIGURATION; 
Configuration 
Name: PRODCONF 
Enabled: YES 
Protection Mode: MaxPerformance 
Fast-Start Failover: DISABLED 
Databases: 
PROD10G - Primary database 
STDBY10G - Physical standby database 
Current status for "PRODCONF" 
SUCCESS

How to find the server is whether standby (slave) or primary(master) in Postgresql replication ?

-
Method 1 You can check the mode of the server using "pg_controldata". [pgsql@test~]$ pg_controldata /usr/local/pgsql/data84/ Database cluster state: in archive recovery --> This is Standby Database Database cluster state: in production --> This is Production Database [Master] Method 2 You can use pg_is_in_recovery() which returns True if recovery is still in progress(so the server is running in standby mode or slave) postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- t (1 row) If Return    false   so the server is running in primary mode or master postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- f (1 row)

7 Steps to configure BDR replication in postgresql

-
Image
 The  BDR  (Bi-Directional Replication) project adds multi-master replication to PostgreSQL 9.4.  Postgres-BDR has a lower impact on the masters(s) than trigger-based replication solutions. There is no write-amplification, as it does not require triggers to write to queue tables in order to replicate writes.   Here We are using  postgres version 9.4.12 and bdr version 1.0.2. for configuring  multi master replication . Simply Following 7 steps you can configure the multi master replication in postgresql. To download the bdr in below link. .   https://github.com/2ndQuadrant/bdr/archive/bdr-pg/REL9_4_12-1.tar.gz $ tar -xzvf REL9_4_12-1.tar.gz $ wget https://github.com/2ndQuadrant/bdr/archive/bdr-plugin/1.0.2.tar.gz $ tar -xzvf 1.0.2.tar.gz 1. To install BDR. $ cd ~/bdr-bdr-pg-REL9_4_12-1 $ ./configure --prefix=/usr/lib/postgresql/9.4 --enable-debug --with-openssl $ make -j4 -s install-world $ cd ~/bdr-bdr-plugin-1.0.2 $ PATH=/usr/lib/postgresql/9.4/bin:"$PATH" ./c

How to Get Table Size, Database Size, Indexes Size, schema Size, Tablespace Size, column Size in PostgreSQL Database

-
In this post, I am sharing few important function for finding the size of database, table and index in PostgreSQL. Finding object size in postgresql database is very important and common. Is it very useful to know the exact size occupied by the object at the tablespace. The object size in the following scripts is in GB. The scripts have been formatted to work very easily with PUTTY SQL Editor. 1. Checking table size excluding table dependency: SELECT pg_size_pretty(pg_relation_size('mhrordhu_shk.mut_kharedi_audit')); pg_size_pretty ---------------- 238 MB (1 row) 2. Checking table size including table dependency: SELECT pg_size_pretty(pg_total_relation_size('mhrordhu_shk.mut_kharedi_audit')); pg_size_pretty ---------------- 268 MB (1 row) 3. Finding individual postgresql database size SELECT pg_size_pretty(pg_database_size('db_name')); 4. Finding individual table size for postgresql database -including dependency index: SELECT pg_size_pretty(pg_total_rel
