ORA-01001: invalid cursor tips oracle bug 6823287 Oracle Error Tips by Burleson Consulting The Oracle docs note this on the ora-01001 error*: ORA-01001 invalid increase the area size and maxopencursors options cursor Cause: Either a host language program call specified an invalid cursor or the value of the MAXOPENCURSORS option in the precompiler command were too small. All cursors must be opened using the https://www.techonthenet.com/oracle/errors/ora01001.php OOPEN call before being referenced in any of the following calls: SQL, DESCRIBE, NAME, DEFINE, BIND, EXEC, FETCH, and CLOSE. The Logon Data Area (LDA) must be defined by using OLON or OLOGON. If the LDA is not defined, this message is issued for the following calls: OPEN, COM, CON, ROL, and LOGOFF.

If there is no problem with the cursor, it may be necessary to increase the MAXOPENCURSORS option value before precompiling. The ORA-01001 error occurs when: a host language program call gave an invalid cursor for use the value of the MAXOPENCURSORS option in the precompiler command was too small You can fix the ORA-01001 error by: Check your problematic call statement for any issues Specify a correct LDA area or open the cursor as required As a last resort, increase the MAXOPENCURSORS option value before precompiling As a note, the ORA-01001 error does not exist in Oracle 10g, according to the Oracle documentation. OraFaq.com has the following to say about the ORA-01001 error: This is 100% a program logic problem. You have either forgotten to code an open statement before using a cursor, or have not noticed that the cursor has been closed and have tried to continue using it. The following checklist may help identify the fault: Make sure you have an OPEN statement prior to using any explicit cursors. Make sure that you do not have a misplaced CLOSE statement.

Oracle. 0 Comments End-to-end performance tuning is something you hear more and more about. I have seen many presentations about how the "modern" DBA has to be intimately concerned with all layers of the application stack and cannot just focus on the database. I'm on board with that, but the reality is, I have rarely seen it in practice. The only time DBAs, developers, and netops folks seem to venture out of their silos is during crisis meetings and in emergency-situation chatrooms. A case in point was when I was asked to troubleshoot an invalid cursor error on a client's database. Here's the helpful documentation Oracle provides for this error: oerr ora 1001
01001, 00000, "invalid cursor"
// *Cause:
// *Action: Hm. I guess that this is one of those things you're just supposed to "know". Actually, invalid cursor is generally a problem with the application design. Perhaps the code is squandering resources and opening too many cursors. A common solution is to jack up the value of MAXOPENCURSORS. (Note that this is not an Oracle parameter as some people seem to think. It's precompiler option. Meaning that you set this in a C header file and recompile your application in order to change it. But don't ask me about this stuff; I'm a DBA, not a developer, remember?) Well, there was no chance of throwing this problem back on the developers and saying "it's your problem, fix it." The application in this system is a black box, the source code is unavailable, and the vendor who wrote the software is long gone. Must be a pretty sweet time for the developers in this shop; they get to spend their days with their feet up or playing foosball. Thus it was up to us DBA-types to come up with a solution. Where to begin? The error arose when a user of the application tried to change her password through the web interface. Our first thought was of course to look at the full error message, which provided the line in the code where the error arose: 09/20/2009 12:24:13 => User edit failed:
