Did you know that you can send your z/VSE SDAID trace to a VTAPE ?

In case of a problem with your z/VSE system it may be necessary to trace your application or workload. SDAID may be used to analyze such problems. Please see the z/VSE Diagnosis Tools book for details. The trace output may be directed (OUTDEV) to a printer, real tape or the SDAID buffer (BUFFER).
If you want to get the trace output to a virtual tape (VTAPE),
Note: When the buffer becomes full, SDAID wraps around and continues to write event records at the beginning of the buffer overwriting previously stored records. To keep all records, you need to dump the buffer to VTAPE before it is full.
Please verify the SDAID trace to virtual tape in your test environment first, before you use this method for problem analysis.
Thanks to my colleague Sa for trying that out.
As always you will find the mentioned books on our z/VS
