ORA-04061 existing state of package in oracle solution and commands

The error ORA-04061: existing state of package has been invalidated typically occurs in Oracle databases when you try to execute a stored package, procedure, or function that has been modified or recompiled while it was still in use by a session.

Here’s a more detailed explanation of the error components

ORA-04061: This error occurs when the session is trying to use an outdated or invalid version of a package, procedure, or function. The invalidation can happen due to recompilation or modification of the package while it was already in use.

Existing state of package has been invalidated: This indicates that the package you are trying to use had a state (data stored in package-level variables) which has been invalidated due to changes.

Solution and Commands

Recompile the package: You may need to recompile the package to ensure the latest version is available and valid. This can be done using:

ALTER PACKAGE <package_name> COMPILE;

Flush shared pool: Sometimes, flushing the shared pool can resolve the issue, especially if the session is holding onto old versions of the package. Use the following command:

ALTER SYSTEM FLUSH SHARED_POOL;

However, use this cautiously in production environments as it clears all cached SQL and PL/SQL objects, which can impact performance temporarily.

Restart the session: Closing the current session and opening a new one can help if the session is still holding the invalid state of the package.

Investigate dependencies: Ensure that the package, procedure, or function doesn’t have any invalid dependent objects. You can check this using the following query:

SELECT object_name, object_type 
FROM dba_objects 
WHERE status = 'INVALID';
