Changing Default Directories for Indexes, Snapshots, or QueuesLocate this document in the navigation structure

Context

There are default directories for indexes, snapshots, and queues. TREX creates new data in these directories. You can change the default directories. You may want to do this if you are running out of disk space in the existing default directories.

This change has no effect on existing indexes, snapshots, or queues. They remain in the previous default directories. TREX creates new data in the new default directories.

Note

If you want to move existing indexes, snapshots, or queues, contact SAP Support.
