Analytical Ecosystem

During analysis, MAPS Manager groups objects to move and defines the order of the moves. You must make sure there is enough Perm space allocated to move each object.

You can add parallel groups. Parallel groups move multiple objects at the same time depending on the number of workers assigned. If multiple objects are moved in parallel, which are in the same database, you need to make sure there is Perm space available to move all of the objects at once (based on workers).

Parallel groups are skipped if there are time constraints. Before running a group, MAPS Manager checks to see if there is enough time to finish moving the objects within the group. If there is not enough time, the group is skipped. MAPS Manager continues checking until a group that fits the available time slot is found. Skipped groups are retried in the next move.

If there are serial and parallel groups, the first worker is allocated to the serial group. Serial order moves one object at a time in order using one worker. The other workers are allocated to parallel groups. If the serial list finishes during a run and the parallel list still has actions remaining, during the next run, all workers are allocated to the parallel group.

When you delete a group, you select a new group to contain the objects. You can also change the order the objects appear in the new group.
