Recently we upgraded one of our DWHS Database from version 10.2.0.4 to 12.1.0.2 and we notice after upgrade the ETL jobs with huge volume of data if failing often with the below error:
DATA_EXTRACT: ORA-12592: TNS:bad packet DATA_EXTRACT: DBMS.CODE=ORA-12592 DATA_EXTRACT: ORA-03113: end-of-file on communication channel DATA_EXTRACT: ORA-03114: not connected to ORACLE DBMS.CODE=ORA-03113 DATA_EXTRACT: ORA-03114: not connected to ORACLE
Solution:
We have to add the below parameters in sqlnet.ora file of both Server and Client ORACLE_HOME.
Client – sqlnet.ora file:
Add "SQLNET.SEND_TIMEOUT=600"
Server – sqlnet.ora file:
SQLNET.ALLOWED_LOGON_VERSION_SERVER=8 SQLNET.ALLOWED_LOGON_VERSION_CLIENT=8
After modifying these values all ETL jobs is running without issues. This is just a workaround not a permanent fix.
