Re: What's an IASP?

Al's main beef with iASP was they weren't implemented the way he wanted them to be. Trust me, he and I had many a spirited discussion about them, all the way back to V5R2 when they were introduced along with cross site mirroring. Yikes that was a long time ago. Things have changed quite a bit since then.

James, the biggest issue with iASP and the application is to remember that work management to the extent you need to worry about it does change. You have to be sure each job has the iASP set properly, which is easy to do but requires an extra step. Also referring to the IFS changes since you will have to set the path as '/myiASP/nowmydirectorystring/whatever' so the IFS objects are found in the iASP IFS instead of *SYSBAS. A few symbolic links can ease that effort quite a bit.

Remember you have two copies of DB/2 (one in *SYSBAS) and one in the iASP. They have to have different names and be in the relational database directory list, you can't rely on *LOCAL for a database name anymore. You'll have two copies of the IFS, so addressing needs to be correct.

I think you tend to run Apache/Tomcat. Apache configs and web sites can live in the iASP IFS, but I don't know about Tomcat, I rather doubt it will be happy there. Zend is nearly ready with a statement on iASP, Mike can fill that in as they get to it. WAS can have the applications live in the iASP but the WAS server itself must be in *SYSBAS. (See technical document 599166201)

There are some other nuances but the Redbook for iASP at V6R1 is the best guide to start with (SG24-7811-00)

This is really when I miss the input of Al Barsa. Al would have given you
an answer from your perspective. Remember how he ranted against IBM
including more libraries in the library list, or increasing the number of
spool files for one job? Basically because all of the QUSRTOOLS that
counted on the lower numbers would have to be modified.
Basically I think James is looking for what will change based on his
perspective. Sorry James, I've never seen an IASP outside of the IBM lab.
I can't give you any help here.

Sent by: midrange-l-bounces@xxxxxxxxxxxx A customer called to ask about any compatibility issues between our CRM product and a Power HA system using IASP from IBM for disaster recovery. This is the first I've heard of IASPs. I've found the Redbook about it, but I'd also kind of like to know what the collective wisdom of the List can tell me about them. I remember one time, years ago, when some QuestView users got bitten by ASPs, and I had to modify some things in the code, for compatibility; do IASPs have any potential to bite? -- JHHL
