ORA-01000: maximum open cursors exceeded tips

This issue is caused by the open_cursors in Oracle. Oracle docs note this about ORA-01000:

ORA-01000 maximum open cursors exceeded

Cause: A host language program attempted to open too many cursors. The initialization parameter OPEN_CURSORS determines the maximum number of cursors per user.

Action: Modify the program to use fewer cursors. If this error occurs often, shut down Oracle, increase the value of OPEN_CURSORS, and then restart Oracle.

It happens when the application attempts to open more ResultSets than there are configured cursors on a database instance. Alter the open_cursors value to fix this issue:

ALTER SYSTEM SET open_cursors = 1000 SCOPE=BOTH;

Check the open_cursors value with:

SHOW PARAMETER open_cursors;
