March 5, 2011 1 comment

Learning to dive, or fly high… I meet my self, keep question why,..

where is my match, do i wonder wrong.. or am i shy,..

Is it passing slow, or my wait’s too tough..

am i lost somewhere, or am i feeling so high..

is this seriousness an issue, or my jokes have fade out..

i’m talking too fast, can u hear me, argh! why..

the time’s not right, or this place, might be..

i’ve a mission, an aim, and my only try..

i’m holding it tight, No worries, My match..!!!

Once its yours, and then ours..
Link a blink of an eye, like sec’s mins and hours..
When you think you own it..
you are done,, you’ve blown it..
Now is no one’s,.. not even its self’s..
It breaks the silence of numbness..
Grabs, holds you back, or Let you free..
Its how how, you take it, how you see..
. . . Every impression you leave.. Every thing you do.. Every move you make..
its there.. Even when you forget it, or when you observe it hard..
Let not the time drive you, You,, You have to rest on it to Fly high..
Even the smallest distinction, turns High.. and big, See it from here.. where i am standing.. am not that high.. I have quit being high.. but Temporal Satisfaction.. No one can decode it.. and if i am late.. not even me..

Slony-I, My Experience – Part 1: Installation

August 26, 2010 1 comment

Slony-I is a trigger-based master to slave(s) replication system of PostgreSQL. In order to get a very brief logical operational idea of Slony the following example shows the master-slave system for replication of (large) databases. Slony-I replicates tables and sequence objects that are grouped in sets having few objects as a proper representation of their independence from its origination. The concept would mean more meaningful after its implementation in real. As the article is the first part focusing installation so a detailed description will be followed in the coming post. From a drama I hear, ‘Evil lies in the details’. So we are skipping it for the time being and will face it when time comes. Read more…

PostgreSQL Point-in-time Recovery (using WAL)

August 12, 2010 1 comment

PostgreSQL is an opensource and free-to-use Object-Relational Database Management System (ORBMS) and is controlled by a group of developers and development companies. PostgeSQL has three modes of backup, i.e. dump, dump all and Write Ahead Log (WAL). I would not focus here on the difference between the three, but will introduce WAL of postgresql. Write Ahead Log is a section of Postgresql where all the psql commands that have been executed are stored. Creating a copy of these logs and executing them again will restore any crashed database. This method is called Point-in-Time recovery, where WAL’s from a certain point in time are re-run to restore (crashed or lost) databases. The tutorial will walk you through the important steps for both backup and recovery of postgresql database using this method.
