Oh, I see. You have date-time with a space, so you need tab. My mistake.

You can specify a field separator with the while loop too:
Code:
while IFS="\t" read ...; do
  ...
done < file

(if "\t" does not work, use a literal tab, or press Ctrl-V then Ctrl-I)

actually there are many spaces in the input file so i will need to work on using tabs. see 1 line sample below.

Code:
2013/08/07 05:07:38:642 CRITICAL        Oracle       Oracle:server.ecs.testpoc.com:Customer D: Oracle Database Server 11G - Basic:Database Counter: Instance Status        server.ecs.testpoc.com   Metric 'Alert has no defined Metric' changed status from 'good' to 'error'      Metric 'Alert has no defined Metric' crossed 'back to default' with value 'null'        DatabaseCounter Alert has no defined Metric     server.ecs.testpoc.com:287a96af-9af1-4431-b689-e1293f612786:Alert has no defined Metric::CRITICAL        server.ecs.testpoc.com:287a96af-9af1-4431-b689-e1293f612786:Alert has no defined Metric  CiHint:@@server.ecs.testpoc.com  ::null  Oracle@@server.ecs.testpoc.com                http://server.ecs.testpoc.com:8080/Oracle/servlet/Main?activeid=200708448&activerighttop=dashboard&view=new&dashboard_view=Details&dashboard_model=true&sis_silent_login_type=encrypted&login=%28sisp%29knjxbqDESkAn5mKcvgTmj%2FyFwHH5Ke3m%0D%0A&password=%28sisp%29EzqXbIXEFD%2BJbE1N1T%2FZlELjja0DKaN7%0D%0A        OracleMonitor:OracleDatabaseServer11GBasic:200708448 1

This actually breaks while loop limit which can accept 9 variables.

Not really. You could just use more parameters:
Code:
while read DATE TIME ...

Old 08-07-2013
nah, i cant do that the error messages will have variable spacing in them, especially for long or short error messages. so the only way is to delimit using tabs.

---------- Post updated at 07:03 PM ---------- Previous update was at 06:44 PM ----------

none of the above works, tried with IFS="\t", literal tab control v and control i. hmmm

Please post your code.

Also paste the output of:
Code:
$ head -1 file | awk 1 RS='\t'

(where file is the input file)

sure. here is the input file

Code:
[oracle@server logs]$ head -1 /opt/application.log | awk 1 RS='\t'
