Hi RudiC

I tried both of your suggestion and they both work fine with test2.log but not with test1.log. Is there any way to get it to work for both or do I need to use different awk code for each?

Code:
$ head -100 test*log
==> test1.log <==
2018-07-23 13:19:38 * (CONNECT_DATA=(CID=(PROGRAM=JDBC Thin Client)(HOST=__jdbc__)(USER=mickey))(SERVER=DEDICATED)(SERVICE_NAME=work_app.com.ph)) * (ADDRESS=(PROTOCOL=tcp)(HOST=12.123.11.123)(PORT=53102)) * establish * work_app.com.ph * 0
2018-07-23 09:12:12 * (CONNECT_DATA=(CID=(PROGRAM=SQL Developer)(HOST=__jdbc__)(USER=minnie))(SERVICE_NAME=work_app.com.ph)(SERVER=dedicated)(INSTANCE_NAME=testp11)) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.214.14.29)(PORT=53548)) * establish * work_app.com.ph * 0

==> test2.log <==
2019-05-12 04:17:10 * (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=fail_app.com.ph)(CID=(PROGRAM=C:\Windows\system32\exec01.exe)(HOST=MNLAPP01)(USER=!sysadmin01))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.11.11.123)(PORT=62625)) * establish * fail_app.com.ph * 0
2019-05-12 04:17:10 * (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=fail_app.com.ph)(CID=(PROGRAM=C:\Windows\system32\exec02.exe)(HOST=MNLAPP01)(USER=!sysadmin01))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.11.11.123)(PORT=62627)) * establish * fail_app.com.ph * 0
2019-05-12 04:17:10 * (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=fail_app.com.ph)(CID=(PROGRAM=C:\Windows\system32\exec03.exe)(HOST=MNLAPP01)(USER=!sysadmin01))(INSTANCE_NAME=xxxt23)) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.11.11.123)(PORT=62626)) * establish * fail_app.com.ph * 0
2019-05-12 04:17:11 * (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=fail_app.com.ph)(CID=(PROGRAM=C:\Windows\system32\exec01.exe)(HOST=MNLAPP01)(USER=!sysadmin01))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.11.11.123)(PORT=62629)) * establish * fail_app.com.ph * 0

These connect strings are from the Oracle DB listener logs and it contains several version of these connection strings. So far, these are the only two formats that I've seen, hopefully there is not another one.

What am currently doing is grep and re-direct all of them to a file and then further break down those two files based on (CONNECT_DATA=(CID= and (CONNECT_DATA=(SERVER=DEDICATED) and then run those four (4) awk and paste for each set and then combine them both Smilie. If I found another version of how the CONNECT_DATA looks like, I supposed I create another for that case. Not sure if there is any other way around it.

Would have been if Oracle themselves had provided their own parser Smilie

NAME
OpaL::manipulate - Perl extension for manipulating files. SYNOPSIS
use OpaL::manipulate qw(functions); No functions or variables are exported automaticly so you have to specify them here. DESCRIPTION
OpaL::manipulate is a module for manipulating files. All functions are autoloaded so they will not be loaded into memory if you have not used them before. FUNCTIONS
perlmodifyadvanced It simply applies the script to the file to change its content. You also have to apply a message to tell what you are doing mostly for debugging and if any error occures. The error level tells how critical this action is to the script. USAGE: "perlmodifyadvanced"("file", "script", "message", errorlevel); The errorlevel is optional. perlmodify It simply fixes some stuff in the script string and then calls perlmodifyadvanced. USAGE: "perlmodify"("file", "script", "message", errorlevel); The errorlevel is optional. perlmodify_insertafter This function searches for something (regular expression). It if is found it inserts the text after it. But it will never insert the text twice. You also have to apply a message to tell what you are doing mostly for debugging and if any error occures. The error level tells how critical this action is to the script. USAGE: "perlmodify_insertafter"("file", "find", "text", "message", errorlevel); The errorlevel is optional. AUTHOR
