SDSF DA in sysplex
A customer currently uses RMF to provide DA information in SDSF; with sysplex scope. They are now joing another sysplex which will have up to 13 members, and SDSF DA command is performing badly due to slow response from other systems. Is there some way to retain sysplex DA capability while restricting the scope to just the customer's 2 LPARs ?

But you can restrict the use of the SYSNAME command or force it to default to the current system in the ISFUSER exit for all but "privileged" users. I still force "LOG S" (syslog) if someone issues the LOG command due to past performance problems with the OPERLOG (because the LOG preference is saved in the profile). If someone wants the operlog they have to specify "LOG O".We also protect the operlog logstream, but that is a different issue.

Re: SDSF DA in sysplex
Thanks Mark, that's what I thought. Pity the LPARs don't start with the same characters, I could have forced SYSNAME XX* or whatever... Paul -Original Message- I don't think there is.

RMF should be running in SYSSTC and access to the data is from the sysplex data server. Also, looking at the doc... perhaps you could prevent access from the other systems using the ERBSDS.MON2DATA RACF profile in the FACILITY class. I've never done this, but it looks like it would be defined on all the other systems you don't want to see in the DA display. Since it would still make the RACF call on the other system, I don't know what this would do in your scenario in regards to performance. But if the userids don't match on the other systems or aren't defined, then even a SYSNAME * should allow just a subset of just the systems you are adding to the sysplex to be displayed. See the RMF and SDSF manuals for more information.

Re: SDSF DA in sysplex
You could also use the SYSNAME * and then have them enter two filter lines for SYSNAME EQ xxyy where just those two systems are included in the list. Can't say if it'll perform any better, but it's worth a try!
