actions "Restart BW server" and the "Restart BWA index server". While

When this action is executed, BW accelerator services are not available
during the restart. In certain circumstances, the restart may take some
time. This means that queries cannot be executed against the BW
accelerator. It is also not possible to index data.
For security reasons, this action is deactivated by default. If you want
this action to be available in your system, you must reactivate it.
To activate the "Restart host" action, you must enter the following
parameters in table RSDDTREXADMIN by using the "rsddtrex_admin_maintain"
report (with the "INSERT" option):

You must then restart the BW accelerator monitor.
To deactivate the function again, execute the report once again; enter a
value in the OBJECT field only and choose one of the options UPDATE or
DELETE.
