Hello and welcome to the forum,

At the top of the page is a link to "IBM Manuals". Down the list are some DB2 Messages and Codes. Look in one of these for the reason for the -904 and proceed from there. I prefer the "DB2/UDB Messages & Codes".

You should be aware that this is a db2 return code, not cobol.

If you find something that is not clear, post what you found and your doubt. Someone will be able to clarify.

I know that -904 is resource unavailable abend. I get this abend while running COBOL program which runs a SQL query to delete data from database.I want to know if there is any way i can override this aband to delete the data.

I hope its clear now.

Hello,

Pause and reflect. . . .

Why would you believe there is a way to delete "things" from something that is not available. . .

Of course this cannot be "overridden".

Imagine the nightmare if all programs could violate the internal controls of the database system. . .

Well, no.

First, the -904 is not an abend, it is a SQLCODE denoting an error. I and other senior members of these fora know what you mean despite your misspeaking, but it is a good idea to learn proper terminology.

Now, a -904 SQLCODE has only one basic meaning: the query failed because a resource was not available. What resource and why is was unavailable may vary, of course (but note that there will be other information available to you that explains this), and the situation may range in severity from annoying to disastrous, but it is an error. Pry your tired carcass out of bed, roust out those lazy DBAs and sluggish crisis managers, and fix the problem.

Do not put a Band-Aid® on a festering wound and go back to sleep. The day will come when your company or your client suffers a loss of tens or hundreds of crores because of it, and suddenly all fingers will point at you.

diptivashishta,
One way is to code loop for 'n' number of time to perform the same delete sql when you get -904. Of course if resource is not available for longer time, this will abend as well.

Thanks,

Hello,

One of the (if not the first) things to do is determine which resource is not available and why it is not available.

Many organizations will not permit production code to "loop a while" to see if a more acceptable sqlcode is returned. . . They prevent these thru proper scheduling. . .

The program is written to delete the data and after deleting 5000 records it gives -904 resource unavailable SQL code. The program has been coded to commit after every 100 records. I have even tried after taking exclusive lock on the table but it still gives this SQL error after deleting some records.

Format the error message using DSNTIAR and display it in SYSPRINT. Then, if necessary, corral senpai and/or DBAs to explain the message and correct the situation.

diptivashishta,

-904 UNSUCCESSFUL EXECUTION CAUSED BY AN UNAVAILABLE RESOURCE. REASON reason-code, TYPE OF RESOURCE resource-type, AND RESOURCE NAME resource-name

See if this helps --> -904 analysis
Please post your abend message associated with -904.

Thanks,
