opidcl aborting process unknown ospid (xxxx) as a result of ORA-1000

By looking the error message we can easily find out the issue

01000, 00000, "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.

First you need to work with application team and find out why the cursors are not closing.

If required you can increase the OPEN_CURSORS value by running below command.
ALTER SYSTEM SET open_cursors = 400 SCOPE=BOTH;

Note that to increase the value of OPEN_CURSORS no downtime required, but cursor storing require more memory.
