IDCAMS ALLOCATE AND PDSE V2

Possibly not of great interest but I found it curious that the IDCAMS ALLOCATE command does not support PDSE V2. Also LIKE does not copy the V2 attribute. Neither limitation appears to be explicitly mentioned and no relief in the z/OS 2.4 pubs that came online :-( I don't really want to change

Hi Martin, My view is that customers will add the Co:Z Target system toolkit (a linux package) to their existing Docker images where they need to integrate Docker apps with z/OS. So, the system architecture (how many containers per zCX instance, etc) is really driven by the customer. This

In reply to David and others, a couple of points that might be of interest: * I confirm that the MIGRATABLE attribute is just as people have suggested, to indicate whether a program can be copied between PDS and PDSE, or saved as a load module in a PDS when it was able to be saved as a program

Very interesting, Kirk. I wonder how you would architect a solution with Co:Z z/OS Hybrid batch in zCX. I'm interested in how many you'd put in one address space, how many address spaces, etc. The answer will be "it depends" so let's just cut to the "on what and how?" follow up question

z/OS containers have been discussed here, so I hope that this post isn't considered out of bounds. z/OS V2R4, when generally available, will be supported by all currently supported releases of Co:Z. In addition, we have tested and will be supporting z/OS Container Extensions. Co:Z z/OS Hybrid

Re: Local time in C on z/OS

David, I really like what you have done for non-POSIX environments. We have code that runs in blind-dubbed POSIX environments, and what we do is to manually read /etc/init.options and set any environment variables from there (that are not already set/overridden).Seems like a good idea for us

Hi John, The easiest way to "re-duplex" would be to run MERGE, using the duplex volume as input. You would specify the original volume key. The merge process will see that the primary volume is disabled, so it will use the duplex volume as input to the merge. It will create a new duplex as

G'Day, Would anybody have an example to create an ARCHPRIM tape.  The original ARCHPRIM was written over (user error).  As a quick fix I ran IXUPDATE with  RESET KEY=199664,DISABLE.  This replaces the original ARCHPRIM.    Thanks.

Will things that used all the non-reusable ASID like DB2IRLM just use the reusable ones when they get recycled? Jim Mulder is, as usual, correct. The answer is "No". But maybe you can help those in the future by submitting a requirement that DB2's components exploit reusable ASIDs. Peter
