7.5 Handling of Couple Data Sets

LOGR couple data sets contains the current LOGR policy and also the inventory of the offloads data sets. This means that system logger uses the inventory to understand on which data set the data for a particular log stream is located once that they are offloaded from the interim storage.

For this reason it is important that the current LOGR couple data set are preserved across IPL. For this reason,

  • Every time you switch to a new LOGR couple data set, you should remember to update the COUPLExx parmlib member to point to the new data sets to avoid inconsistency when you will IPL later on

  • Every time that you perform an IPL without having updated the parmlib member, you will receive message IXC287I to describe the discrepancy between the parmlib member and the last used data set. In this case, you should reply 'U' to message IXC289D to continue the IPL with the last used couple data sets and update the parmlib immediately after IPL completes.
