Re: What's an IASP?

A couple thoughts that clarify this, I hope! And one that I know will be helpful.

1. The IASP lives in the IFS under its name, as shown.
2. The rest of the IFS is still available - maybe an obvious statement, but I put it here, anyhow
3. Native RLA access should not need additional setup - that is all library-based, after all, and libraries are just handled behind the green curtain for IASPs

The database comment is where things get interesting. I seem to remember that I ran RJS' WebDocs in an IASP - had to verify it'd work - and I used SQL in it. It did not seem to have a problem - but that was maybe 4 years ago - YMMV

4. I like IASPs for test environments - put a menu option on for entering one or the other, each would SETASPGRP as needed.
5. Apache loves IASPs - but all the Redbook used to say was that it could be set up, with no hint of how. Maybe there's been a revision. So here's how - merely pass the IASP path in a directory directive - say you have CGI stuff - then <directory /myiasp/qsys.lib/mycgilib.lib> does it and bob's your uncle! Might need to be uppercase or case-sensitive. Apache will autmagically run SETASPGRP on your behalf - lovely!

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.

Subject: What's an IASP? 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
