To avoid contention among disk accesses, a user LOB RDAREA should not be placed on the same disk as any other RDAREA.

In the case of a table containing a LOB column in a HiRDB parallel server configuration, the user LOB RDAREAs containing the LOB data and the user RDAREAs containing the LOB column structure base table must be placed on the same back-end server.

The following figure shows an example of user LOB RDAREA placement.
