People working for DMSU
The DMSU people are categorized into two groups:
- Assigners, i.e. the prime technical contact person pr. partner and also the one to conduct the initial assignment of tickets following the TPM assignment
- Resolvers, extra experts at each partners to which the assigner can delegate tasks when needed either due to technical reasons or due to overload of one of the other staff members.
The lost of people, with a short list of expertise areas relevant for DMSU follow here:

DMSU shifts
The main purpose of DMSU shift is no surprise: keep the things running, not to leave an important issue without fast reaction etc.
The shifts are held by groups of people with expertise on different middleware stacks. However, due to the prevailing gLite-related traffic in DMSU only gLite shifts are formally organized currently, the other stacks are handled on the best effort basis.
The specific duties of the person on shift are:
- to follow incoming emails from GGUS, being able to react within approx. 2 hours in normal working hours
- to identify "top priority" and "very urgent" issues, not only by the priority set by the submitter but also by using common sense, and to make sure an appropriate expert starts looking into the issue; this includes assigning the ticket to a specific person
- to keep checking that there is reasonable response time, namely as a reaction to further submitter's correspondence; it should be almost immediate on "top priority", and we can probably afford upto 1 week for "less urgent"
One person holds the shift for one week, the duty is passed to the other on Monday afternoon.
