Maintenance
TRIDENT Services provides a growing
list of clients with a low cost, efficient
and well organized means of maintaining their z/OS and related
operating system software as supplied by both IBM as well as independent vendors.
Services are tailored to the specific needs of each client and include the mix,
frequency and level of on site and on call support desired. In house staff is
relieved from time spent researching and applying periodic maintenance and is
freed for use on other projects of strategic importance to the client.
Specific tasks performed include analysis, acquisition, customization,
installation and testing of all new releases to z/OS and related
software as defined by the client. Analysis includes the identification of
necessary prerequisites, co-requisites and hardware engineering changes required
to support any particular new software release. Necessary APAR and PDZAP
acquisition, installation and testing are also performed. Specialized code or
CLISTS necessary along with appropriate documentation can also be provided.
Maintenance is applied to the client's test system LPAR using TRIDENT
Services' SMP/E methodology. This methodolgy provides a concise and stable
mechanism for applying and tracking maintenance. All staff members will be aware
of the status of the datasets involved and the level of maintenance on the
running system making more efficient use of both manpower and processing
resources. TRIDENT Services also provides a methodology document which includes
update techniques, volume layouts, SMP/E structure, catalog structure, library
structure, apply processing, accept processing, maintenance method and naming
conventions.
Following satisfactory performance in the test LPAR, maintenance is certified
by TRIDENT Services as ready for implementation in the production environment.
TRIDENT Services briefs the client staff on significant changes being introduced
and assists in placing maintenance into production. TRIDENT Services remains on
call on a 24 by 7 basis to respond to emergency situations. TRIDENT Services
support staff is linked by leased line network from each TRIDENT Services support
site to each client site for remote diagnostic and fix purposes.
Clients provide facilties and computing resources necessary for TRIDENT
Services to complete the desired maintenance activities.
