PDB service not pingable after db tier cloning and configuration

[VinodN]

Hello Erman,

During rapidclone procedure, after completion of db tier cloning and config (as per 2552208.1, till step 4.1.8), tnsping PDB_SID fails with could not resolve error (sourced CDB env file). After manually adding the tns entry from network/admin/CONTEXT_NAME/tnsnames.ora in network/admin/tnsnames.ora, tnsping is successful. Is this expected behaviour or something is wrong?

Hi,

tnsnames generation is in the later steps ... ->

Here;

4.2.8 Create the listener.ora and tnsnames.ora Files for the Target CDB
Create the listener.ora and tnsnames.ora files for the target CDB by running the following commands:

$ cd <ORACLE_HOME>/appsutil
$ source ./txkSetCfgCDB.env -dboraclehome=<ORACLE_HOME>
$ cd <ORACLE_HOME>/appsutil/bin
$ perl txkGenCDBTnsAdmin.pl -dboraclehome=<ORACLE_HOME> -cdbname=<Name of the target container database> \
-cdbsid=<SID of the target container database> -dbport=<Target DB port> -outdir=$ORACLE_HOME/appsutil/log \
-israc=<yes/no> [-virtualhostname=<virtual hostname>]
