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 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(…

PostgreSQL Pgbadger Installation On Linux

-
Image
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.

The report output by pgBadger has the following features. Graph output in HTML format Many statistical objects Daily, Weekly unit creation possible 1.Graph output in HTML format
Many of the analysis results can be displayed in graph form by outputting the report in HTML format (output in text format or JSON format is also possible). By analyzing the log information graphed, it is much more prospective for people to see than the raw log data. So, if you do not need to handle it with another tool separately, we recommend report output in HTML format.

2.Many statistical objects A lot of data useful for database performance analysis is output in the report as shown below. Queries (total number of executions, maxi…

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
