That cursor uses resources on the database server. It is NOT sufficient to only release Java client resources for that SQL cursor.
If you are using the statement named ‘dbmssql.opencursor()’ then there is need to close that cursor using dbmssql.
OPEN CURSORS ORACLE CODE
The Java app layer creates and consumes cursors - without closing the cursor on the database server when done. Developers as well as DBAs needs to check the PL SQL code and close all cursors which are open. Which they proved that they are not by their Java code haemorrhaging SQL cursors. It needs to be fixed by these code monkeys that think they are capable of writing code and using Oracle. Syncfusion Dashboard Server tries to execute 300 SQL statements per connection by considering the default opencursors limit. By default, Oracle database allows 300 opencursors per connection session. OPENCURSORS specifies the maximum number of open cursors (handles to private SQL areas) a session can have at once. Kindly provide any solution to rectify the problem either at DBA end or Developer end.It is a developer problem. The cursor might be used for retrieving data on a row-by-row basis like a looping statement. We have oracle linux 6 with 11g database, 16GB RAM Current sga is 6gb Select max(a.value) as highest_open_cur, p.value as max_open_curįrom v$sesstat a, v$statname b, v$parameter pĪlso tell us that what should be the best value for open_cursors parameter, SGA and PGA size. Kindly provide any solution to rectify the problem either at DBA end or Developer end.Īpplication Server: Glass Fish using Java version 1.6 The problem occurred and We increase the limit to 2000 but that figure also not enough so We try to increased the cursors limit to 5000 but now we have again the same issue, cursors are increasingly rapidly.As with discussion of our developer they are trying to close the cursor but still they are not succeeded.Īlthough We know the limit of 5000 cursor is very bad management but we have to do it as long as the problem get resolve by developers. Before 3 months the database had only 300 cursors in Open_cursor parameter but gradually We have Open Cursor issue in oracle 11g database version 11.2.0.1.0. 1.7K Training / Learning / Certification.165.3K Java EE (Java Enterprise Edition).7.8K Oracle Database Express Edition (XE).The initialization parameter OPENCURSORS determines the maximum number of cursors per user.
When the open cursors exceeds the maximum limit you will get the below error: ORA-01000: maximum open cursors exceeded Cause: A host language program attempted to open too many cursors.
