TNS-12203: TNS:unable to connect to destination

edited Dec 13, 2011 7:55PM in Oracle Forms (MOSC) 5 commentsAnswered
I am having trouble connecting to 10g oracle database using 6i forms. I am able to tnsnping and make a sqlplus connection to database using 10g client executable without any issues. Forms and Reports are configured to use 8i executable. The sqlnet.log reports following error messages:
TNS-12203: TNS:unable to connect to destination
TNS-12538: TNS:no such protocol adapter
TNS-00508: No such protocol adapter

The technical forums suggest that i should reinstall forms and reports to resolve this issue. https://forums.oracle.com/forums/thread.jspa?threadID=1082981
