While working with Oracle E-Business Suite 19c, generating CDB TNS Admin entries using the txkGenCDBTnsAdmin.pl script may fail on Linux with the following error:

Can’t locate TXK/ARGS.pm in @INC (you may need to install the TXK::ARGS module)

This blog explains the cause and a simple solution to make the script run successfully.

Issue

run the following commands:

cd /u01/8051/db/19.3.0/appsutil
source ./txkSetCfgCDB.env -dboraclehome=/u01/8051/db/19.3.0

cd /u01/8051/db/19.3.0/appsutil/bin

/u01/8051/db/19.3.0/perl/bin/perl txkGenCDBTnsAdmin.pl -dboraclehome=/u01/8051/db/19.3.0 -cdbname=EBSCDB -cdbsid=ERPCDB -dbport=1572 -outdir=/u01/8051/db/19.3.0/appsutil/log -virtualhostname=ebs

Error returned:

Can’t locate TXK/ARGS.pm in @INC (you may need to install the TXK::ARGS module) (@INC contains: /u01/8051/db/19.3.0/perl/lib/site_perl/5.28.1/x86_64-linux-thread-multi /u01/8051/db/19.3.0/perl/lib/site_perl/5.28.1 /u01/8051/db/19.3.0/perl/lib/5.28.1/x86_64-linux-thread-multi /u01/8051/db/19.3.0/perl/lib/5.28.1) at txkGenCDBTnsAdmin.pl line 72.

Solution

Start a Fresh Session

• Open a new terminal session
• Log in as the db user

Set Environment Cleanly

cd /u01/8051/db/19.3.0/appsutil
source ./txkSetCfgCDB.env -dboraclehome=/u01/8051/db/19.3.0

Run the Script

/u01/8051/db/19.3.0/perl/bin/perl txkGenCDBTnsAdmin.pl -dboraclehome=/u01/8051/db/19.3.0 -cdbname=EBSCDB -cdbsid=EBSCDB -dbport=1572 -outdir=/u01/8051/db/19.3.0/appsutil/log -virtualhostname=ebs

Script should run successfully without the TXK::ARGS.pm error

Conclusion

The “Can’t locate TXK/ARGS.pm” error in Oracle 19c txkGenCDBTnsAdmin.pl is environment-related, not a missing module.

Permanent practice for Oracle 19c DB-Tier scripting:

1. Open a fresh Putty session
2. Source environment only once
3. Run required Perl scripts

This ensures smooth execution and avoids Perl library path conflicts
