Is there such thing as Index Limit within the VMS directory or some sort? I know there is a version limit but not sure about Index Limitation. As you can tell, I am also new to VMS.
Thank you in advance.

Re: Index Limit - VMS 7.3-2
- a disk volume has a limit on how many files are allowed, specified during INIT
- when creating new files, the index file on [000000] fills up and is extended and may eventually fill up its fileheader, then no more files can be created. You may preallocate room for entries in the indexfile when INITing the disk
- too many files in one directory may slow down performance during certain operations (not a real limit...)

SolutionIf your problem is the indexfile, only ha BACKUP/RESTORE will help (or delete some files:-))
You may always specify a high number for /MAXIMUM_FILES, it costs nothing.
A good utility for disks is the DFU utility, often mentioned here and available via the OpenVMS freeware pages. It has a REPORT function, which tells all about your disk.

Re: Index Limit - VMS 7.3-2
SHOW DEV/FULL disk will show 'Maximum files allowed'
Are you trying to solve a real problem or is this question for your educational purposes only ? If you have a real problem, it would be good to provide the full error message and circumstances, under which the problem is seen.

Re: Index Limit - VMS 7.3-2
DFU REPORT

Re: Index Limit - VMS 7.3-2
It's possible your vendor means "version limit" on a file. OpenVMS allows up to 32767 versions of a file, for example: application.log;32767 is a possible file name. After this limit is reached attempts to create a new version of the file will fail. Purge won't solve the issue since it leaves the highest versions, you either need to delete or rename the file(s).

Re: Index Limit - VMS 7.3-2
from the info seen so far I would guess that Andy hit the point.
What is your VMS version? Recent versions have simple commands to find out if he is right; if not, then there also are ways, albeit somewhat less simple.
If we know IF he guessed right or wrong, we can proceed from there.
Please help us to help you.
Proost.
Have one on me.
