Contiguous space in a disk on VMS

[Ian Miller.]

DFU was written by the Wizard of ODS2 and should be included with VMS. Certainly it should be installed on any VMS systems you have.

As to the original question - what are you trying to do? I wonder if you need to know this.

[Sk Noorul Hassan]

During my application startup after VMS boot, the start up getting terminated with an error "insufficient space, disk full' while trying to create section files on the system. My disk size is 2GB and free space available is almost 1.8 GB

[Hein van den Heuvel]

Hmmm... what is the EXACT message. I don't recognize yours directly:

FUL, device full (insufficient space for allocation)
VOLUME_FULL, volume is full (insufficient space for the request)
DEVICEFULL, device full; allocation failure
:

And how big are those section files going expected to be?

2GB drives (RZ26?) are not too big compared to physical memory and virtual memory these data.
You know that when you initialize a disk, the defautl place for INDEXF.SYS is in the middle right? So max contig would be 1GB, unless one uses INIT/INDEX=...

Are you sure it is a problem with the data disk? Could it be the audit system running out of system disk of something like that?

Hein.

[Ian Miller.]

have you used one of the methods described to determine the largest contiguous free space?

[Ian Miller.]

Do you know why the application wishes to create a contiguous file?

[John Abbott_2]

Sounds more like you should just backup and restore (ie. defrag the volume).. assuming you have the hardware and time.

Also, as per Marc's suggestion with DFO, I thought this HP product was free to use in report mode ?

Failing that, try the freebie report image tool from HP...

The exact error is, device full; allocation failure

Can it be solved by taking Image backup to a different disk and restore it back ?

[Wim Van den Wyngaert]

I would do "anal/disk/rep" for the disk first. Maybe the free space counters are not correct. Maybe you should do a cleanup.

I did clean up and ana/disk/repair for the disk, still the problem exist. I am unable to create a file of space 10000 blocks also.

[Wim Van den Wyngaert]

Then you need to backup and restore, as said.
Or buy defrag.
