3.1 IEBCOPY problems
A new version of IEBCOPY was provided with z/OS 1.13. Unfortunately, this version was not
compatible with older 3990 control units as emulated by zPDT. The result was that an
IEBCOPY compress operation would sometimes corrupt a partitioned data set, making it
unusable. z/OS PTF UA67459 corrects the IEBCOPY problem.
z/OS 1.13 also contains a copy of the older IEBCOPY version, which works correctly with
zPDT. The problem may be bypassed by using the older IEBCOPY program. It is located in
SYS1.LINKLIB under the name IEBCOPYO. You can make this older version your standard
version by doing the following:
򐂰 Use ISPF option 3.4 to list the members of SYS1.LINKLIB.
򐂰 Use the line command “R” to rename IEBCOPY to IEBCOPYX.
򐂰 Use the line command “R” to rename IEBCOPYO to IEBCOPY.
򐂰 Issue MVS the command F LLA,REFRESH.
At the time of writing we did not know whether PTF UA67459 will be integrated in z/OS 2.1, or
whether the IEBCOPYO program will be included with z/OS 2.1.
3.2 z/OS CP and memory display
The d m=cpu command should display the following information:
d m=cpu
ID CPU SERIAL
00 + 000971090
CPC SI = 1090.306.IBM.02.000000000000097
d m=stor
REAL STORAGE STATUS
ONLINE-NOT RECONFIGURABLE
0M-3500M
where 1090 is the System z machine type and 97 is the System z serial number assigned by
our 1090 USB hardware key. Each 1090 hardware key assigns a different System z serial
number.

3.3 z/OS spin loop timeouts
A a z/OS spinloop may time out and produce an S071 ABEND. This is because the default
timeout is set for a faster “real” processor. You can change this time value by creating or
altering member EXSPATxx in PARMLIB:
member EXSPAT00
SPINRCVY ABEND
SPINTIME=60
In the z/OS 1.13 AD-CD system we created ADCD.Z113.PARMLIB member EXSPAT00 and
then issued the MVS™ console command SET EXS=00 to immediately activate the member. It

Or the serial number may be provided by a UIM server.
