Data Sharing members, different times

Data Sharing members, different times
Does anyone know of anyone who is running multiple data sharing members
with one member being on a different time than the other members??
Please, don't ask me why, I am opposed. But there is a client with the
need.

Regards,
Richard

Richard,

This statement is from the DB2 Data Sharing Guide: "At least one Sysplex
Timer must be installed in the Sysplex. The Sysplex Timer keeps the
timestamps of the S/390 processors synchronized for all DB2s in the data
sharing group. DB2 data sharing uses a value derived from the timestamp to
recover data using the log.'

Could you clarify what you mean by "different time"? Thanks.

Rick,
My assumption would be that the customer has a sysplex, but one of the
members of the sysplex runs with a different timezone parm coded in the
CLOCKxx member of parmlib. I never even considered if that is doable, but
since DB2 only cares about the GMT time, it may work, I don't know if I
would want to try it though.

The LRSNs need to be running the same time, or logs and recovery will be a
disaster. Different time zones might be possible, but this is certainly
outside of manufacturer's design, test or support. Several customers noted
that setting the clock back during their Y2K testing did not work.
