TxkOnPremPrePDBCreationTasks.pl fails With Error "ERRORMSG: Could not fetch DB_NAME"

Hi All,

I am upgrading my 12.2.11 environment from 12c to 19c - I finished section 2.4 and I am starting section 2.5 from doc 2552181.1. Now I need to Convert Database to Multitenant Architecture. On first steps I run:

ORACLE_HOME = /opt/oracle/VIS/19.0.0

ORACLE_SID= VISCDB

Then, Connect into database and make sure it is up.

$sqlplus “/ as sysdba”

SQL > startup

SQL> show pdbs;

I only see

$ cd $ORACLE_HOME/appsutil

$ . ./txkSetCfgCDB.env dboraclehome=/opt/oracle/VIS/19.09.0

$ export ORACLE_SID=<source SID from 12c db [VIS]>

$ cd $ORACLE_HOME/appsutil/bin

$ perl txkOnPremPrePDBCreationTasks.pl -dboraclehome=$ORACLE_HOME \

-outdir=$ORACLE_HOME/appsutil/log -appsuser=<apps user> -dbsid=<source SID from 12c db [VIS]>
