UID Translation

Tony_289 — Tue, 14 Apr 2009 16:58:02 GMT

Hello,
My site is documenting all access points (E.g., use of ports, Decnet objects) into a given VMS system. (versions 7.1 up to 8.3). We have found most, either through various documentation or output from applicable NCP or NCL commands. When researching reserved objects 42,69,82, and 86, we noticed that their characteristics only showed the object number and other "default values". The only "useful" piece of information was the UID Process identifier.

Does anyone know of a way to translate the UID into something more meaningful? Perhaps back to a PID or image? I believe the last part of the UID represents the ethernet address. Btw, we have found our information on the above objects.

command as reference: MCR NCL Show Session Control Application 86 All

Thanks for any time spent on this -- Tony

Tony,

any entity in DECnet-OSI, that has counters or generates events is assigned a unique identification (UID) value, a 16-byte entity attribute that is unique throughout the network and for all time. It includes the creation time and the local network address.

You cannot use the UID to get more information about the entity itself. It's just a number.

Volker.

Tony,

SDA> NET SHOW SESSION ASSOCIATIONS

may reveal more information about those 'unknown' session control applications.

Thanks Volker! The Net Show command is what we are looking for.

Volker's suggestion to use the SDA command answered my question
