A couple of notes if you have, or are thinking of, embarking on use of the Feature Pack for Web Services, based on a recent client’s experiences. Firstly, make sure you heed the rules on profile augmentation in the InfoCenter. In particular, note that augmentation of a Cell profile is not supported. For Network Deployment you must have a separate deployment manager profile.
Secondly, if you are experiencing sluggish response times, 100% CPU or even hangs when either deploying or accessing applications following augmentation, then consider applying APAR PK58537. Note that the application need not be using any new functionality in order to experience this behaviour and it’s possible that you might not see the particular IOException stated in the problem description. This fix is targeted for inclusion in 22.214.171.124.
