CMSReserveElement Warning

[Trace Trembath]

We are using the CMS software (CMS Version V3.9-2) and few days ago one of our staff received the folowing message;

CMSReserveElement Warning: CLEARSTONE_PKG.DQL not found

The command was;

$cmsreserve clearstone_pkg.dql

However, the module is definitely in the library. Does anyone know what might cause the above error even though the element is in the CMS library.

Thank you.

Regards,
Trace Trembath

CMS sho elem may show the element, but the file may have been deleted. The best way to determine if the file is present would be to do a directory [cms_library...]clearstone_pkg.dql and see if the file shows up.

Another possibility is that the file is on a member of the volume set that is not mounted, but that might be a different error.

It appears you have a local wrapper around the CMS utility, with a symbol named cmsreserve that invokes it. This wrapper could be a DCL procedure, or it could be an image using the callable CMS interface.

The error message shown is most definitely not an error from CMS itself, based on the format and content.

You'll need to investigate the details of the environment, in addition to investigating the CMS library itself.

An unexpected local definition of the CMS$LIB logical name can potentially cause a procedure go go off the rails, for instance. What happened appears to depend on what this local command procedure does. There exists a limitless number of ways for a procedure or an image to go off the rails.

The first step: issue the DCL command SHOW SYMBOL CMSRESERVE to see where that symbol goes, and from there off you go on your quest.
