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 errors or rem…

How to configure Replication Manager (repmgr) ?

-
`repmgr` is a suite of open-source tools to manage replication and failover within a cluster of PostgreSQL servers. It enhances PostgreSQL's built-in replication capabilities with utilities to set up standby servers, monitor replication, and perform administrative tasks such as failover or switchover operations. The current `repmgr` version (3.3) supports all PostgreSQL versions from 9.3 to 9.6. Overview The repmgr suite provides two main tools:1.repmgr - a command-line tool used to perform administrative tasks such as: - setting up standby servers - promoting a standby server to master - switching over master and standby servers - displaying the status of servers in the replication cluster 2.repmgrd is a daemon which actively monitors servers in a replication cluster and performs the following tasks: - monitoring and recording replication performance - performing failover by detecting failure of the master and promoting the most suitabl…

Migrating From Oracle to PostgreSQL using ora2pg open source tools

In this blog we are going to talk about migrating from oracle to postgresql using ora2pg.
After installing ora2pg tool, we will see how to configure and to run it to migrate our data. We are using an oracle 12C database and a postgresql edb 9.6, The server is runing on OEL 7.2,The oracle database and the postgresql server are running on the same server.

we are going to talk about migrating from oracle to postgresql using ora2pg open source tool
before migrating you need to know little bit knowledge of functions,procedure,trigger and  Difference between oracle vs postgresql data types

1.Oracle Installation 12C
2.Oracle instalaltion 11gr2
3.postgresql installation 9.3
4.postgresql installation 10.3

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_relation_size(…
