Hi Radoslaw, That's true, but I believe the OP was asking whether the entire data set was limited to 64K tracks and I believe only PDS and PDS/E are limited to one volume. https://www.ibm.com/support/knowledgecenter/SSLTBW_2.3.0/com.ibm.zos.v2r3.idad400/d4002.htm None of my database data sets (DB2, IMS, Adabas) are limited to one volume. Cheers, Mick.
