Re: Quick question about QHSTxxxxxx PFs

James

The QHST* files should be processed in the order of their text descriptions - not their names - especially not their names.

I wouldn't use creation date and time, actually. When I wrote some stuff around this about 12 years ago, I never even thought of using creation date/time - the text descriptions are telling you the date/time range of the messages in each particular history file.

DSPOBJD to output file can certainly get you a list you can sort, then on that description. Take a look at yours - I can't see any QHST* stuff with my profile on any system I have access to right now.

There is potentially a lot more information in many of the messages - you've already figured out to use a sequence number there - CPF1124 and CPF1164 - I think the latter, esp. - have stuff in at least 3 records, IIRC - maybe up to 5, I forget. Work Management and/or the message handling chapter in CL Programming have the information you need for all the performance stuff in CPF1164.

Have fun!

James,

James,

As an alternative to DSPOBJD you could use a combination of the following APIs to build an array, user index or keyed table.

Create User Space (QUSCRTUS) API
Delete User Space (QUSDLTUS) API
List Objects (QUSLOBJ) API
Convert Date and Time Format (QWCCVTDT) API if you want to convert date and time in format OBJL0400
Retrieve Pointer to User Space (QUSPTRUS) API or Retrieve User Space (QUSRTVUS) API to obtain the list contents

If you only want the QHSTxxxxxx names and descriptions, QUSLOBJ format OBJL0200 will give you that information pretty quickly. Interpreting the text will give you the PF's creation date and time.

Subject: Quick question about QHSTxxxxxx PFs

Filter-funneling the first two records of all history log entries pertaining to specified jobnames into a receiver file, programmatically, in chronological order, with a CL program calling an RPG Cycle program.

If I do this,

DSPOBJD OBJ(QSYS/QHST*) OBJTYPE(*FILE) +
OUTPUT(*OUTFILE) OUTFILE(QTEMP/HISTLIST)

to get my list of the extant history log PFs on the system, are the records in HISTLIST then guaranteed to reflect a chronological sequence of QHSTxxxxxx files?

Or do I need to use a keyed receiver file in order to force chronological sequence?
