Dear all,

we are facing a problem, your suggestions and comments will be very helpful here.

Actually what happens is that we are connected to oracle through forms 6i. suddenly we receive the error
" ORA-06508: PL/SQL: could not find program unit being called "
while doing some transaction.
we have searched on net and meta link. they say that the package / procedure called has become invalid or recompilation has occurred and that is not compatible.
Now we have monitored carefully that there are no changes what so ever has been made in the the package/ procedure.

what could be the reason behind this.
we have also checked the global variable issue. we use package level variables but declared in the package body only. (so these are not public)
what you say ?
Need your opinion.

Thanks

Ahmad Saeed

Are you getting that error still?

As oracle suggested at may happen when ever the object gets invalid statement due to teh dependent object re compilation or any error occured on that object or its dependent object.
If it successfully compiled then you wont get that error.Didi you try to connect through that after some time? whats happend ?

Thanks dear,
yes this is the problem, we re-login the problem is gone.
Now why that object gets invalid even compiled all right (if changes were made).
and if the object was invalid then why re-login solved the issue.

The problem should only be occurring when trying to attempt a call first time, re-attempt should solve the issue without re-login.

what do you say ?

At that moment the dependent objects are in the compiling position....so once the process completed successfully...the object comes to the normal state so you are able to run perfectly...

Goodluck

well,
the error continues to show even after hours of compilation. only re-login clears the error.

By rereading your post..

Your are saying ...For each and every time when ever you are logging to that form the problem occured ?


Quote:

sounds doing some dynamic ddl`s are some code changes at runtime?Which may cause the object used in you form invalid.

please post some more information.

Nops,
There are no DDLs in the process. only update, delete and inserts in tables and some calculations.

ORA-06508: PL/SQL: could not find program unit being called 
Cause: An attempt was made to call a stored program that could not be found.
 The program may have been dropped or incompatibly modified, or have compiled with errors. 
Action: Check that all referenced programs,
 including their package bodies, exist and are compatible.

Dear all,
Let me explain it again ,
There is an application (APP )developed in oracle developer 6i,
the user logs in and a session is created on the database Oracle 10g R-2. OK
The user is working in forms all right and there is no problem. suddenly on one of the forms (FORM1) when a button (B1) is pressed (a back end procedure is called ) the system shows the error : ORA-06508: PL/SQL: could not find program unit being called . (Earlier this was working all right and no errors)
Now the user tries pressing the B1 again and again but no use.
user exits the form1 and open the form1 again but same problem at B1, now user exists the APP and log in again, now new session is created and all is fine again. every thing is ok.
and in the DB we have made no changes, or have made few changes. but every thing compiled all right. (Some procedure was re-compiled)
my question is that why this error occurs ? when no object is invalid. still if there is an object stat change then pressing the B1 twice should resolve the issue as oracle says the procedure is re-complied when called.
why new session is required.??
hope i have described the problem in detail.

Why and how they were re compiled ?
Whats the reason behind that!

"Modified by the incompatable version"did you modified the any thing using oracle 10g developer?

Sorry dear could not get your point
incompatable version of what??

we are working on a big application. some time user logs in and keep on working for hours. and if there is some change required in procedure / dependent procedure (May be just adding a space , or changing the string).
that is not the issue that what is changed. the issue is why we re-login . is it default behavior of the DB. i dont think this ..

There is no involvement of 10g developer.
we user PLSQL developer and TOAD for writing DB packages and procedures.
the B1 buttons calls the procedure residing at db not the form.

changing the string may require re compilation of code and its dependents.
BUt as you stated that each and every time you are getting this error at the first logging right?
Have read the links posted?
specially the your path?
If not search at Metalink which may help you...
and i doubt you are mixed up the thing here?
whats the significance of oracle 10 developer here?
are you modifying the forms?
If so using of which version 6i? or 10g?(check the compatability)( are you migrated?).i guess you are mixing the database and forms issues here!
What happend when you compile your form ?does it succeded?

Dear thank you very much for continues replies

There are no changes made in the form. the form is same all the time. (no re-compile no change)
The changes are only made in the Database level procedure P1. that is called on the when_button_pressed button trigger of B1.

This is the code
This is just a procedure call.

this should not happen

Sorry that I have been so long in replying. Have you solved your problem?

When you change the procedure in the database it is given a new 'object_id' when the new code is inserted and the old code deleted. As your existing session is trying to access the procedure using the previous 'object_id', it will not be found. Therefore, the session has to be closed and a new one started. This is standard Oracle Database behaviour. You should NOT change code while a user is working. If you wish to do this then use dynamic SQL to make the call for you. Just remember that it has to be parsed every time you make the call.
