Or is SQA automagically > increased? UCBs were nucleus resident back when they were defined by IOGEN and later MVSCP. When defined in an IODF, they are in SQA/ESQA. Based on the contents of the IODF, IPL processing tries to estimate the SQA/ESQA requirements for UCBs and some other I/O related control blocks, and adds this to the initial SQA/ESQA size (the default size defined in IEAIPL04 plus the INITSQA in LOADxx, if specified). UCBs get built before the SQA= parameter in IEASYSxx is processed (since we need the UCBs for devices containing the data sets in the PARMLIB concatenation in order to open the PARMLIB concatenation).
