To set the system parameters

Set the Oracle system parameter OPEN_CURSORS to indicate the total number of cursors you want to have. Look in Oracle's init.ora and initSID.ora, or any other database initialization files used at your site, and add or modify the line:

open_cursors = nnn

The number of cursors can be equal to the number of keys times the number of segments per key for each file. For example, if you have 5 files, each of which has 3 keys, and each key has 3 segments, you should set OPEN_CURSORS to a minimum of "45".

Note: Setting OPEN_CURSORS should be performed only by your system administrator or database administrator, because it affects all applications using the database.
