ORA-1000 After Upgrading To JDBC With WebLogic 12.1.3 (Doc ID 2174682.1)

Last updated on AUGUST 30, 2023

Applies to:

JDBC - Version and later
Information in this document applies to any platform.


When trying to use JDBC with WLS 12.1.3, encountered the error 'maximum cursor limit exceeded'.
<Patch 19632480> - ORACLEDATABASEMETADATA.GETTABLES CURSOR CONNECTION LEAK was applied, but the ORA-01000: maximum open cursors exceeded error persists.

This forces JDBC 11g to be used with WebLogic 12.1.3 application datasources, with which the error does not occur.

ORA-01000: maximum open cursors exceeded

The issue can be reproduced at will with the following steps:
1. Apply patch 20741228 on top of WebLogic 12.1.3 for production version of JDBC
2. Apply patch 19632480 to fix the issue in <Bug: 19632480> - ORACLEDATABASEMETADATA.GETTABLES CURSOR CONNECTION LEAK.
3. Run the application. The ORA-1000 error will be reported in the WebLogic logs.
