dmpmeminf

We have potential memory constraints. We are particularly interested in particular subsystems/jobs memory usage. We run dmpmeminf and get a grand report, but we cannot find any description of the fields/attributes reported. Below a list of interesting attributes with no description. We found on IBM website somewhere SQL query, but the majority of mem usage is due to MItype 1e and mistype 01 slictype 000F?

OBJNAME           Object name        
LIBNAME           Library name       
MITYPE            Object type        
POOL              Pool id            
MCHPOOL           Page into Mach Pool
BASEPOOL          Page into Base Pool
PAGEREF           Page is Referenced 
PAGE64K           Page size is 64K   
SLICTYPE          Segment type       
MISTYPE           Object subtype

From what I can see it looks as those entries with MITYPE = '1E' and MISTYPE = '01' are stream file accesses (the majority of entries have a SLICTYPE = '0000'). I'm unfamiliar with the command and its output so I have no idea if my results are within the norms or no.

A web search on the command turned up a Red Book on Performance Management Tools that may be of some use to you. There's also an article at iProDeveloper (registration required) that might shed some light on the matter.
