Here is my simple "big hammer" to clear DAE from the z/OS console which can be
very handy to do especially when things are not going well and dumps are not be
captured that are now greatly desired. You can use more surgical tools in ISPF
to take the next dump for a particular set so symptoms but this approach just
emptying the DAE data set is simple.
This particular example uses CA-OPS/MVS but you can substitute a free or
another vendor program to issue a z/OS command passed in a parameter.
Also adjust the name of your DAE data set as needed I have unique names on each
LPAR in a Sysplex.
DAE is generally a very good thing and having it on is desirable as it protects
us from SVC dump flooding and avoids collecting the same dumps over and over
again. Sometimes though you want to clear it all out in a hurry and just get
on with getting the dump needed to get doc for a vendor or IBM.
Once you setup the PROC and define to security you can just do a S DAECLEAR
from a console.
SYS1.PROCLIB(DAECLEAR) - 01.02 Columns 000

Subject: DAE to stop dump suppression
I have a dump that is being suppressed by DAE. I am not experienced with IPCS
and DAE. How do I find out what dataset is being used by DAE and how do I
"remove" the dump in order to get the dump?
I hope that makes sense.
thanks
Bill
