It recently came to our attention that under certain circumstances, attempting to use XDC in task mode FRR debugging causes the address space to hang at a pause. Turns out we had a bug in the Z21-1509H maintenance that allowed an incompatible TCB to be selected and used. This caused the “unpause” to never occur and things end up at a standstill.

This will interest Sysprogs who have to install and maintain the VTAM network nodes that cs-cdf/XDC needs.

I have just posted Z21-1509F that adds System Symbol support (&SYSCLONE &SYSNAME and friends) to server/XDC’s parsing of its //SYSIN parameter file.

I’ve just published update Z21-1506C that fixes a problem in the vector support introduced in Z21-1505F. We were using an incorrect flag bit in one of our vector support checks. Oops! That causes a S0C7-FE abend to pop up when starting a debugging session for a SRB.

I’ve just finished publishing update Z21-1505F. It implements vector register support in z/XDC. Vector registers are now saved and restored by z/XDC for both task mode and SRB mode execution.

We’ve just now pushed out an update (Z21-1505E) that adds support for a //xxxNOALC DD DUMMY jcl statement. When this ddname is present in the TIOT, z/XDC will abort any command or internal service that attempts to use Dynamic Allocation (SVC 99).

We want to thank Bob Edmond of BMC Software for requesting this feature.

A couple years ago, we discovered that we had posted some bad maintenance and we had no way of knowing how many times it was downloaded and who had done the downloading. To help deal with this, we built an interface that requests some basic user information, just a name and email, before the maintenance file can be downloaded. This process gives us a list of users that we can contact in case of an error in the maintenance or an older maintenance has been superseded.

For a couple of months, we have been developing, testing and now finally documenting a new feature for CDF: The ability to connect a user to a debugging session running on a different processor in a Sysplex.

The latest update to z/XDC, Release z2.1, is here! You can check out our z/XDC z2.1 Announcement Video here, and visit the Release z2.1 Page for the highlights.
