At the first IPL after system installation, the system automatically loads the PLPA from the LPALST concatenation. The page data sets for this IPL are those specified in the IEASYS00 parmlib member, plus any specified by the operator.
After the first IPL, you must run IFCDIP00 to initialize the LOGREC data set. This routine must also be run whenever the LOGREC data set is reallocated.
