Datatrieve Access Violation. ACCVIO error.

John Vercamer — Tue, 10 Jan 2006 05:17:07 GMT

When running a big and complex procedure (READY of 34 domains) in Datatrieve (v7.2), it dumps with an access violation after adding and IF and FOR statement to read the 34th domain.

DTR> :downl-miles-ctr

%SYSTEM-F-ACCVIO, access violation, reason mask=00, virtual address=000000000860
%SYSTEM-F-ACCVIO, access violation, reason mask=70, virtual address=200000000000

Improperly handled condition, image exit forced.

Register dump:

SP = 000000007AF11760 PC = 000000000014ED70 PS = 200000000000001B

When putting the FOR in comment and only keep the IF statement, following error occurs :

DTR> :downl_miles_ctr
Stack overflow, PC=0000000000000001, PS=00000000

Has anyone an idea why ?

Improperly handled quota exceeded ?

And what do you mean with "quota exceeded" ?

I am not very familiar with VMS technical issues.

Thanks, John

If you do
$ sh proc/quota
you'll see a number of limitations for your process such as open file. This limit comes from the user definition. If it is too low, you are unable to open files behind a certain point. Post the output of this and
"mc authorize show [userid]" if you need help.

John,

I'm practically ignorant on Datatrieve, but

WELCOME to the VMS forum!

Proost.

Have one on me.
