ISPF does not record the alias name in SMF14ALIAS when accessing datasets via their alias

When browsing or editing datasets under ISPF, if the dataset is accessed through an alias, ISPF uses the real name to access it, rather than the alias. Other allocation services, such as JCL, use the alias. In z/OS 2.1, a new field in the SMF type...

Move ICSF cell pools above the bar

If a high enough burst of ATTLS requests comes in at once, ICSF cell pools can grow rapidly enough and fill CSF private storage. This results in ABEND878s and TCPIP leaving the sysplex group. At this point, an IPL is likely desired. Moving these c...

CSSMTP needs to redrive DNS lookup other than at startup

Current CSSMTP functionality only resolves DNS names to IP addresses on product startup. PMRs and questions have led to responses that indicate the implementation ignores the DNS time to live (TTL) parameters and, quoting from the PMR, "... elimin...

Add default symbols to system symbols

In IEASYMxx processing, HWNAME, LPARNAME and VMUSERID are available for filtering but they are not available as built-in system symbols. Please make these available for use as symbols within IEASYMxx processing, e.g. &LPARNAME(2:1) and as syst...

Add a possibility to limit the number of parallel tasks to prevent S878 ABENDing HSM STC

During recover of over 1000 datasets we increased the maximum recover tasks step by step to 12. Once we reached 12 HSM STC itself ABENDed because of a S878 because of a storage constraint below the line. This is documented as works-as-designed: ht...
