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\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
