I got the following error. I closed every statment. How do I set open cursor higher. I used Oracle 9.2. I cannot find init.ora file. Any suggestion will be very helpful.

Thank you very much,

Jance

Hello.

Well, you can set it by the open_cursors parameter, however, you have to ask yourself why you're hitting this problem at all? Are you correctly closing your cursors after you've used them?

See http://asktom.oracle.com/pls/ask/f?p=4950:8:9253786818282941511::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:1041031921901
for a good discussion on this.

Thank you very much. I sure I closed the cursors after I used them. Do you know how to set the open_cursors? Where? Do Oracle 9.2 have init.ora file? Because I don't have the file.

Hello.

What's your open_cursors set to now?

Go to SQL*Plus and type

SQL> show parameter cursors

NAME                                 TYPE        VALUE
------------------------------------ ----------- ---------------------
open_cursors                         integer     300
session_cached_cursors               integer     20

Oracle 9i CAN have an init.ora (PFILE), but most DBAs create SPFILEs which have certain advantages.
A way to see is if the spfile parameter is set, i.e.

SQL> sho parameter spfile

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
spfile                               string      C:\ORACLE\PRODUCT\10.2.0\DB_1\DBS\SPFILEORCL.ORA

You can modify the parameter via

SQL> ALTER SYSTEM SET open_cursors=1000;

System altered.

But, seriously, if your database has a relatively high open_cursors (i.e. it's not 5 or something! Wink

Wink

), then you have to wonder why you're hitting this at all....

Thank you very much. I used SQL Plus worksheet.

SQL>show parameter cursors, and show parameter spfile
it gave me the following answer.

ORA-00942: table or view does not exist

And I tried to set the maximum cursors, it gave me the
following message:

ALTER SYSTEM SET open_cursors=1000
*
ERROR at line 1:
ORA-01031: insufficient privileges

I don't know what do I do wrong. I am new to use Oracle.
Any suggestion will be very helpful.

Thanks again,

Jance

Hello.

Yes, you'd need to login as a user with enough privileges to do this. Can you not ask your DBA to help you?

How does this relate to the max open cursors problem?!
How do you call your packaged procedure? You have to prefix it with the package name.

What is the relation bewteen:
ORA-01000: maximum open cursors exceeded
and
PLS-00201: identifier 'PR_CREATE_CLOB' must be declared

You can increase open_cursor to 100000000000, you will still have the same error.

It is your code and objects, I don't know nor have them, only you can answer the reason of the error.
All what you can say is that Oracle is unable to find an object named 'PR_CREATE_CLOB' in the scope it searches it.

Recompile it and if it is still invalid then there are other errors.
Query user_errors.
