Last updated on FEBRUARY 28, 2023

Applies to:

Enterprise Manager for Oracle Database - Version and later
Information in this document applies to any platform.


When navigating to Administration -> Storage -> Tablespaces page of a target database from Cloud Control, the list of tablespaces is never displayed. The returned error is:

Error java.sql.SQLException: ORA-01000: maximum open cursors exceeded

Increasing the value of the open_cursors parameter at the target database does not resolve the problem.

On the target database, run the following update:

The resultant trace file contains this entry:

Open cursors(pls, sys, hwm, max): 3(0, 2, 64, 500)   <=== In this case open_cursors is 500, using only 3 NULL=0 SYNTAX=0 PARSE=0 BOUND=2 FETCH=1 ROW=0 
----- Current SQL Statement for this session (sql_id=6hnhqahphpk8n) ----- select free_mb from v$asm_diskgroup_stat where name=:1
