One of the most common errors that occurs is an ORA-01000:
Cause: A host language program attempted to open too many cursors.
The initialization parameter OPEN_CURSORS determines the maximum number of cursors per user session.
Action: Modify the program to use fewer cursors. If this error occurs often, shut down Oracle, increase the value of OPEN_CURSORS. example: alter system set open_cursors = 400 scope=both;
This error happens a lot in association with some kind of application, e,g, an OCI program, Pro*C program, Visual Basic, CDE Tools (Reportwriter, Forms, etc.), Financial Applications, etc.
This error also happens at the database level, with just regular inserts, updates, deletes, etc. in PL/SQL or in SQL*Plus, etc.
