Enable archive log in Oracle RAC

-
In this Tutorial I explained  about  How to Enable Archivelog In RAC Environment
Step1: stop database instance on node1 using sqlplus.
[oracle@rac-node1 bin]# sqlplus /nolog
SQL> select instance_name from v$instance;
TEST1
SQL> shutdown immediate;
Step2: Stop database instance on node2 using sqlplus.
[oracle@rac-node2 bin]# sqlplus /nolog
SQL> select instance_name from v$instance;
TEST2
SQL> shutdown immediate;
Step3: start only one instance i.e node1.
SQL>startup mount;
SQL>alter database archivelog;
SQL>alter database open;
Step4: Now connect node2 and start the instance only.
[oracle@rac-node2 bin]# sqlplus /nolog
SQL>startup
SQL> select log_mode from v$database;
SQL>archivelog     #it means database is in archive log mode
DISABLE ARCHIVELOG MODE IN RAC.
Step1: stop database instance on node1 using sqlplus.
[oracle@rac-node1 bin]# sqlplus /nolog
SQL> select instance_name from v$instance;
TEST1
SQL> shutdown immediate;
Step2: Stop database instance on node2 using sqlplus.
[oracle@rac-node2 bin]# sqlplus /nolog
SQL> select instance_name from v$instance;
TEST2
SQL> shutdown immediate;
Step3: start only one instance i.e node1.
SQL>startup mount;
SQL>alter database noarchivelog;
SQL>alter database open;
Step 4:Now connect node2 and start the instance only.
[oracle@rac-node2 bin]# sqlplus /nolog
SQL>startup
The Following Command shows the database whether archivelog or not
SQL> select log_mode from v$database;

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
