Modifying shared data sets

You can allow two or more systems to share access to the same library directory. When modifying or stopping LLA in this case, your changes must take effect simultaneously on all systems that share access to the directory.

In cases where you simply want to update an LLA-managed data set, it is easier to remove the data set from LLA management and update it, rather than stopping LLA on all systems. To do so, enter a MODIFY LLA,UPDATE=xx command on each system that shares access to the data set, where 'xx' identifies a CSVLLAxx member that specifies, on the REMOVE keyword, the data set to be removed from LLA management.

When you have completed updating the data set, enter the MODIFY LLA,UPDATE=xx command again, this time specifying a CSVLLAxx parmlib member in which the keyword LIBRARIES specifies the name of the data set.

In any case, whenever multiple systems share access to an LLA-managed data set, STOP, START, or MODIFY commands must be entered for LLA on all the systems.
