Shared Pool Tuning: Cursor Tuning The three most important parameter for shared pool tuning are OPEN_CURSORS , SESSION_CACHED_CURSORS and CURSOR_SPACE_FOR_TIME. But most of the time we see that these two parameters SESSION_CACHED_CURSORS and CURSOR_SPACE_FOR_TIME are ignored or unused . OPEN CURSORS Open cursors take up space in the shared pool, in the library cache. OPEN_CURSORS sets the maximum number of cursors each session can have open, per session. For example, if OPEN_CURSORS is set to 1000, then each session can have up to 1000 cursors open at one time. V$open_cursor shows cached cursors, not currently open cursors, by session. If you’re wondering how many cursors a session has open, don’t look in v$open_cursor. It shows the cursors in the session cursor cache for each session, not cursors that are actually open. To monitor open cursors, query v$sesstat where name= ’opened cursors current’ . This will give the number of currently opened cursors, by session:
On exporting using network link in the remote server, where will be the server process for expdp will be started. Whether the expdp server process will be started in source database server or remote database server?
