Oracle 04068错误排除指南（oracle 04068）

Oracle Error 04068 indicates that there is an error in the package state or the configuration of the current session. This issue is not caused by Oracle database, but by some codes or other external factors. Hence, to address this issue, we must follow the steps outlined in this guide.

First, we need to investigate the code to find out what kind of package the Oracle database is trying to execute. Through the Package Body, the Program ID and the Package Name, we can identify the specific package used by the application. Once identified, we can proceed to debug the Active Session.

Next, before debugging the Active Session, do a quick check to see if there is any invalidated PL/SQL code. If the code is invalidated, recompile it to reset the flag as valid. This should stop the 04068 error.

If the recompiling does not solve the problem, or if the PL/SQL code was not invalidated, enter debugging mode. To debug, use the DBMS_DEBUG package to trace PL/SQL statements. This way, we can identify which package is causing the issue, and then correlate it to the Active Session.

After tracing the Active Session, we can narrow down the issue to either the SQL and PL/SQL code, or the configuration of the current session. If it’s the latter, we must alter the configuration. For example, if the Session’s open_cursors parameter is lower than the number of cursors used by the code, then increase the number to satisfy the package and address the 04068 error.

Once configuration is set correctly, we still must ensure the correct execution of the SQL and PL/SQL statement. To check this, run two SQL queries to check the execution and optimization plans for the code. If the execution and optimization plans are incorrect, the 04068 error will continue to occur.

Finally, resetting the package, even if it doesn’t solve the issue, can be beneficial in some cases. To do this, first find and drop the package, and then recompile it.

In conclusion, resolving the Oracle 04068 error requires determining the type of package being executed and then debugging the session, ensuring the configuration of the current session is correct, and then resolving any issue related to the execution and optimization plan of SQL and PL/SQL code. Finally, resetting the package may have to be considered.
