Shutdown/Startup The CRS, OHAS, ASM & RDBMS Services on RAC

-
The present document provides in detail the steps to shutdown/startup The CRS, OHAS, ASM & RDBMS Services on a RAC 11.2. Configuration:
1) Connect to node 1, then please check if the CRS/OHAS & services are enabled to autostart as follow (repeat this step on each node):
# $GRID_ORACLE_HOME/bin/crsctl config crs
2) If not, then you can enable it as follow (repeat this step on each node):
# $GRID_ORACLE_HOME/bin/crsctl enable crs
3) Shutdown the services on each node as follow:
# $GRID_ORACLE_HOME/bin/crsctl stop crs
4) Verify the services were/are down (repeat this step on each node):
# $GRID_ORACLE_HOME/bin/crsctl status resource -t
5) Then start the services on node #1 as follow (only on first node):
# $GRID_ORACLE_HOME/bin/crsctl start crs
6) Wait 1 minute, then validate the services started & diskgroups were mounted (only on first node):
# $GRID_ORACLE_HOME/bin/crsctl status resource -t
7) Then start the services on node #2 as follow:
# $GRID_ORACLE_HOME/bin/crsctl start crs
8) Wait 1 minute, then validate the services started & diskgroups were mounted on node #2:
# $GRID_ORACLE_HOME/bin/crsctl status resource -t
9) If there are more nodes in the RAC, then repeat the same steps (7-8).

Script to find sessions that are blocking other sessions in PostgreSQL

-
In this post, I am sharing a script to find sessions that are blocking other sessions in PostgreSQL. Instead of finding blocked sessions or processes, sometimes it is better to find those sessions which are the root of blocking. PostgreSQL DBA can use this script to find the cause of blocked transactions. SELECT pl.pid as blocked_pid ,psa.usename as blocked_user ,pl2.pid as blocking_pid ,psa2.usename as blocking_user ,psa.query as blocked_statement FROM pg_catalog.pg_locks pl JOIN pg_catalog.pg_stat_activity psa ON pl.pid = psa.pid JOIN pg_catalog.pg_locks pl2 JOIN pg_catalog.pg_stat_activity psa2 ON pl2.pid = psa2.pid ON pl.transactionid = pl2.transactionid AND pl.pid != pl2.pid WHERE NOT pl.granted;

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)

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

PostgreSQL pgBadger

-
pgBadger is a PostgreSQL log analyzer built for speed with fully reports from your PostgreSQL log file. It's a single and small Perl script that outperforms any other PostgreSQL log analyzer. It is written in pure Perl and uses a JavaScript library (flotr2) to draw graphs so that you don't need to install any additional Perl modules or other packages. Furthermore, this library gives us more features such as zooming. pgBadger also uses the Bootstrap JavaScript library and the FontAwesome webfont for better design. Everything is embedded. pgBadger is able to autodetect your log file format (syslog, stderr or csvlog). It is designed to parse huge log files as well as gzip compressed files. See a complete list of features below. Supported compressed format are gzip, bzip2 and xz. For the xz format you must have an xz version upper than 5.05 that supports the --robot option. All charts are zoomable and can be saved as PNG images. You can also limit pgBadger to only report err

How to Return a Result Set from a PostgreSQL Stored Procedure

-
Image
Both stored procedures and user-defined functions are created with CREATE FUNCTION statement in PostgreSQL. To return one or more result sets (cursors in terms of PostgreSQL), you have to use  refcursor  return type. Quick Example : -- Procedure that returns a single result set (cursor) CREATE OR REPLACE FUNCTION show_cities ( ) RETURNS refcursor AS $$ DECLARE ref refcursor; -- Declare a cursor variable BEGIN OPEN ref FOR SELECT city , state FROM cities; -- Open a cursor RETURN ref; -- Return the cursor to the caller END ; $$ LANGUAGE plpgsql; Overview : Return Multiple Result Sets Cursor Lifetime Until the  end  of transaction Auto-commit Must be  off Transaction must be active so the caller can see a result set Important Note : The cursor remains open until the end of transaction, and since PostgreSQL works
