1--Oracle 使用 init.ora 中的初始化参数 OPEN_CURSORS 指定一个会话一次最多可以拥有的游标数。缺省值为 50。要获得数据库中 OPEN_CURSORS 参数的值,可以使用以下查询:2SQL> show parameter open_cursors;3NAME TYPEVALUE4--- --- ---5open_cursorsinteger30067修改open_cursors89SQL>altersystemsetopen_curso...
Currently, I have 300 value set as max cursors. Monitoring the user session overpass this number and at then raises the error. I ignore why is not closing the cursors or if I miss some configuration parameter in the configuration. I have test checked to reduce the maximumPoolSize, but seem...

When reached the max allowed value set for OPEN_CURSORS, the ORA-01000: maximum open cursors exceeded is triggered in the Oracle side. Solution As part of our Database Setup for Oracle in Confluence, we do not specify any minimum value for the OPEN_CURSORS parameter, as Confluence does not...

ora-01000: maximum open cursors exceeded. 表示已经达到一个进程打开的最大游标数。 这样的错误很容易出现在Java代码中的主要原因是:Java代码在执行conn.createStatement()和conn.prepareStatement()的时候,实际上都是相当与在数据库中打开了一个cursor。尤其是,如果你的createStatement和prepareStatement是在一个循环...
a、如果Open_cursors设置太小,对系统性能不会有明显改善,还可能触发ORA-O1000:m~imum open CUrsOrs exceeded.的错误。如果设置太大,则无端消耗系统内存。我们可以通过如下的sql语句查看你的设置是否合理: SQL> SELECT MAX(A.VALUE) HIGHEST_OPEN_CUR, C.VALUE MAX_OPEN_CUR ...
错误信息:"ORA-01000: maximum open cursors exceeded" 客户端在一次连接中可打开的游标数量是有限的(默认值为 50)。您可以使用 stmt.close() 方法来显式关闭语句,关闭和释放游标, 如果您没有显式关闭游标,您就可能遇到这一错误。您可以通过调高 "OPEN_CURSORS" 参数来避免这一问题,但这种方法治标不治本,只能...
