TSSO under zOS 2.3

2021-03-08 Thread Tom Sims
Any one out there running TSSO (CBT File 404) under zOS 2.3? As with many out there a client is trying to get out from under their OEM software obligation.  I have not used TSSO since early OS/390 2.10, but up until then it ran like a charm, no issues, no worries. However I have not used it

BSAM and QSAM with extended format require a level of DFSMSdfp that supports it. EXCP with extended format requires application code to deal with it. The same applies to EAV. Even when striping is handled by the director, you would need the appropriate CCWs to request it. -- Shmuel (Seymour

Why wouldn't they be totally compatible? I would think that striping occurs at a much lower level than QSAM (probably EXCP or lower? maybe "Media Manager" level?) so one would expect that QSAM wouldn't even know it was happening. More sophisticated utilities like SORT may be aware of

Have you considered using extended format sequential striped data sets? Define using a data class with DSNTYPE set to require or request extended format; control the number of stripes (which are read in parallel) using a storage class with a non-zero sustained data rate attribute. Choosing the

It appears that on one of my z/OS 2.4 systems I don't have this ssh issue but on another I do. The difference is that one has a /etc/ssh/zos_ssh_config file and the one that fails does not. Updating the /etc/ssh/zos_ssh_config file thus fixed the problem: Change from: ChannelConvert shell

Rewinding this discussion a bit, to my knowledge there's only one locally FICON-attached physical tape solution for z/OS from one vendor that's still in active development. The current iteration is IBM TS7770+IBM TS4500+IBM TS1150. Physical tape is still extremely useful, even more useful than
