Description
Using this test, you can load all the data for a BWA index from the file
server into the main memory if the data is not already in the main
memory.
This action is useful if you want to ensure that queries executed in the
corresponding InfoCube achieve optimal performance the first time they
are executed and do not have to read data anew from the file server.
Data for an index is deleted from the main memory, for example, when new
data is added to this index (during roll up or a change run). You can
set the BWA index (by choosing <ZK>BWA Index Properties)</><ZK> </>such
that data is loaded automatically to the main memory every time changes
are made.
Note that if you do <ZH>not</> specify an InfoCube, the system executes
the selected action for all BWA indexes that are active and filled.
Repair
This test has no repair.
