Re: [suse-oracle] ORA-12514 error

Hi Trisha,

Your database is installed correctly but listener is not having any
entry for your database instance (orclg).

Check "/etc/profile.d/oracle.sh" for ORACLE_SID entry. or Try "export
ORACLE_SID=orclg" and stop/start Oracle listener i.e. "lsnrctl stop",
"lsnrctl start".

Make sure "lsnrct status" has an entry for your database instance
"orclg" i.e. "Service "orclg" has 1 instance(s). ..."

Hope this will help,
