Starting liveCacheLocate this document in the navigation structure

Prerequisites

In accordance with the authorization concept, the user was assigned one of the roles SAP_BC_LVC_OPERATOR, SAP_BC_LVC_ADMINISTRATOR or SAP_BC_LVC_SUPERUSER.

Context

In the Operating user menu you can, among other things, start an SAP liveCache database (transfer it to operational state ONLINE).

Note

If a user is performing administration functions, administration is locked for all other users.

An SAP liveCache database is started using the Database Manager. The DBM Server executes the control file lcinit.bat with the option restart. In this case, the volumes are not formatted. The data is loaded from the data volumes into the SAP liveCache database. Among other things, the liveCache applications are also registered.
