Error：ORA-41031: Destination session key not specified for sid string serial# string

Description：

ORA-41031 is a database error that occurs when the database session is not able to determine the destination session. This happens when a program makes session-to-session calls without specifying the necessary parameters.

Cause:

The ORA-41031 error is caused by missing parameters when calling a remote database. In this case, the SID and serial number of the desired session to be connected to, should have been mentioned.

Examples:

For example, a JDBC program may want to access a remote database, but since the necessary parameters were not specified, the database throws the ORA-41031 error.

Solution:

The best way to resolve the ORA-41031 error is to ensure that the required SID and serial number of the session to be connected to, is specified in the call. That would be the necessary and sufficient condition to accurately access the remote database, and hence should eliminate this error.

An equivalent solution to the ORA-41031 error is to use database connection pools. A database connection pool would simply store a persistent connection to the remote database and then establish connections from that pool instead of making new connection sessions. This will also resolve the ORA-41031 error, without needing any manual parameters.

Conclusion:

Thus, ORA-41031 is a database error that is caused by missing parameters when calling a remote database. It is therefore important to mention the session key of the desired session, to avoid this error. However, using database connection pools is a better solution as it involves a persistent connection and no cumbersome manual parameters.
