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
nislog - display the contents of the NIS+ transaction log SYNOPSIS
/usr/sbin/nislog [-h num | -t num] [-v] [directory...] DESCRIPTION
nislog displays the contents of the NIS+ server transaction log on the standard output. This command can be used to track changes in the namespace. The /var/nis/trans.log file contains the transaction log maintained by the NIS+ server. When updates occur, they are logged to this file and then propagated to replicas as log transactions. When the log is checkpointed, updates that have been propagated to the replicas are removed. The nislog command can only be run on an NIS+ server by superuser. It displays the log entries for that server only. If directory is not specified, the entire log is searched. Otherwise, only those logs entries that correspond to the specified directories are displayed. OPTIONS
-h num Display num transactions from the ``head'' of the log. If the numeric parameter is 0, only the log header is displayed. -t num Display num transactions from the ``tail'' of the log. If the numeric parameter is 0, only the log header is displayed. -v Verbose mode. FILES
/var/nis/trans.log transaction log ATTRIBUTES
