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).

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

PgBadger is a tool that analyzes PostgreSQL log files and generates reports on execution of SQL and server operation. Statistical reports analyzed from a number of perspectives can be useful not only for grasping the usual database operation but also as a hint for performance improvement.

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
