Friday reverie. I remember when and why we inserted CLPA into IEASYSxx. Mid 1980s. Up to that time disk was considered to be 'slow enough' as to relegate CLPA to specific situations where 'we' (mighty all-knowing sysprogs) knew that LPA had changed in some way since the previous IPL. One day we had a system crash with no operators around. We had to roll up our sleeves and save the day. The chalk board on the wall told us which sysres volume to IPL from. Since it was a simple down-and-up situation, no CLPA was needed.
We began getting the weirdest abend reports. We experienced them ourselves. After much consternation, we determined that we had IPLed from the wrong sysres. Chalk board was wrong. Without CLPA, we were mixing down-level link list with newer LPA list. Random mismatches, random kabooms. We reIPLed the correct way, all better. At the next Change Control meeting, we announced that from then on every IPL would be CLPA. Skepticism abounded but did prevail. I don't think anyone ever actually perceived a difference in IPL time. For sure we never had another LINK/LPA mismatch. . .
