June 2008 Newsletter


Happy Birthday AS/400!  This week our beloved machine will celebrate its 20th birthday (more about that in our third feature article).  How times have changed, and how times have improved. You would have to admit that the AS/400 has seen many great improvements over the years.   In previous newsletters, we covered news on 6.1.  We have other topics this month.

This issue of our newsletter has four articles.  In the first, we’ll take a look at the mystery jobs of V5R4. As performance is an issue in most shops, our second article deals with the number of jobs in your system.  Learn the differences between number of jobs in WRKACTJOB and WRKSYSSTS and how you should properly configure your System values for these. The third article is some commentary on the AS/400’s birthday. The last article has the updated PTF information for your use.

iTech Solutions can help you improve performance, upgrade OS/400, perform security audits, implement a High Availability solution, VoIP, Systems Management, PTF management, upgrade an existing machine, or upgrade to a new machine.  If you are thinking of LPAR or HMC, then think iTech Solutions.

When the Service Monitor starts, a series of watches are initiated. There is one watch for each policy defined in the policy file. There is a one-to-one relationship between a started watch and a job being started. These jobs are named SRVMONxxxx, with the xxxx being sequential numbers.
