received) displays the name of the conflicting job(s). The conflict may be from zFS. The
following MVS console command:
f omvs,stoppfs=zfs
stops zFS and permits compression of the PARMLIB. This should be done when there are no
Unix System Services users, of course.
3.18 Burning 3390 volumes on CD
If we wanted to preserve a 3390 volume on CD (or DVD), we could use the following
command to make a compressed copy:
$ gzip -c /z/Z5RES1 > /z/Z5RES1.gz
We could then burn the compressed file on CD or DVD by using a normal Linux CD/DVD
burning application.
3.19 Delete logstreams
The default location for log streams (for the AD-CD system) is the ZCSYS1 volume (or the
equivalent, for other releases). These streams can sometimes grow to fill the volume. A
typical job for deleting a log stream is as follows:
//BILL1 JOB 1,OGDEN,MSGCLASS=X
// EXEC PGM=IXCMIAPU
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
DATA TYPE(LOGR) REPORT(YES)
DELETE LOGSTREAM NAME(WAS.ERROR.LOG)

3.20 Disabled waits
You may sometimes see a message in your zPDT Linux window such as:
Warning! Disabled Wait CPU 0
$ d psw <--you may issue this command
PSW for CPU 0 000A0000 00000xxx (24/32 bit mode)
PSW FOR cpu 0 00020000 00000000 00000000 00000XXX (64-bit mode)
When you receive such a message, you may issue a command to display the PSW. The last
three characters of the PSW should contain a wait state code; an extended code may be also
present in other characters of the PSW. The following list provides abbreviated information
about standard wait state codes. Please see the System Codes manual for more complete
information about each code. Note that some wait states are restartable; again, see the
System Codes manual for more information.
