120 Data Sharing in a Nutshell
Workload is shifted from one member to another member. This implies that the
applications must be able to run on more than one member. One DB2 member of
the data sharing group is stopped while the other members keep processing the
workload. The system programmer makes appropriate modifications so that
when that DB2 is started again, it loads modules that have the new maintenance
applied. The process is repeated for each of the other members, usually one at a
time, until all the members are running with the new maintenance.
Rolling maintenance across all the members maintains data and application
availability with no apparent outage to end users.
