HI Roger, Beginning with z/OS 1.13, the activation of TEMPDSN no longer interferes with currently running processes, and it is safe to activate TEMPDSN without waiting for an IPL. If you compare the description of TEMPDSN in the 1.12 version of the RACF Security Administrator's Guide with its description in the 1.13 version, you'll find following verbiage has been dropped from the 1.13 version.
(quote) Avoid activating the TEMPDSN class when current users or jobs are using temporary data sets. Otherwise, you could cause users or jobs to receive an ABEND, as shown in the following scenario: 1. The job or user allocates a temporary data set. 2. You activate the TEMPDSN class. 3. The job or user opens the data set. 4. Because activating the TEMPDSN class restricts the authority to open a temporary data set, the user or job receives an abend. (end-quote) Regards, Bob Robert S.

I've heard about improvements with the zOS 1.13 (some year ago) related to the RACF TEMPDSN, however it is being just impossible to me to find that information in any 1.13 manual/migration guide... I've just read and searched several of these manual, but I simply could not find it. Would any of you have any material about it that could share with me ?!
