IMS GHU call and checkpoint restart.

Post by Arun Rajput » Thu Oct 01, 2015 11:44 am


In may of our programs we have GHU calls. We thought that the buffers are only used by Update calls when update executes and will be released after Checkpoint. But DBAs at our company think otherwise. According to them, buffer allocation is high and they want us to do checkpoint cheking during the read calls. Is it necessary to issue Checkpoints during GHU calls also, which is not exsiting at the moment?
