This program was written way back in the 90s and has worked under every release of z/OS until z/OS 3.1.
Under z/OS 3.1, instead of getting our address space and selected data space, we get a lot of data that was not requested, the dump request fails (see below) and the data space is not included.
We issuing the SDUMPX we get the following messages:
IEA794I SVC DUMP HAS CAPTURED: 929

Under previous z/OS versions, our dump dataset would contain the normal DR2 H, SV, SC, A, etc. records, plus our expected DR2 SS.....%00000XXX records, where 00000XXX is our data space.
We have rebuilt the code under z/OS 3.1 but that made no difference. We have also changed the default dump parameters, altered the code to try different dump options, but still no data space and no obvious changes in what is being dumped.
Our SDUMPX macro is as follows:
SDUMPX HDRAD=SDUMPHDR,SUMLSTL=SUMLSTL, X
TYPE=(XMEM,FAILRC),SDATA=(NODEFS,SUM,RGN,TRT), X
MF=(E,SDUMPL)
TYPE=(XMEM,FAILRC),SDATA=(NODEFS,SUM,RGN,TRT), X
MF=(E,SDUMPL)
As I have mentioned, this code has worked under all previous versions of z/OS.
Any help appreciated.
