Initializing the liveCache
In the Operating user menu, you can, among other things, initialize a liveCache database instance.
If a user is performing administration functions, administration is locked for all other users.
A liveCache database instance is initialized by the Database Manager. The DBM Server executes the control file lcinit.bat with the option init. After the liveCache database instance has been initialized, all data in the data volumes and the log volumes is no longer available, as all volumes are formatted. Therefore, no existing data can be loaded into the liveCache caches once the liveCache database instance has started up, rather, all data must be newly built up. Among other things, the liveCache applications are also registered. This is the reason why each initialization process is liable to take some time.
Prerequisites
In accordance with the authorization concept, the user has been assigned the role SAP_BC_LVC_SUPERUSER.
You are in the user menu of the user with the authorizations that correspond to this role.
Procedure

4.
You can schedule
the report with the variant defined by you for background processing
(Define Job (transaction SM36)

Jobs).
Initialization from the Operating System Level
Function Module for Starting/Stopping/Initializing
Process Flow
...
1. The operational state of the liveCache database instance is checked. If the liveCache database instance is in the ONLINE or ADMIN operational states, it is transferred to the OFFLINE operational state.
2. The liveCache database instance is then transferred to the ADMIN operational state and reinitialized.
3. The liveCache system tables are loaded and liveCache monitoring is activated.
4. The DB procedures are loaded.
5. The routines of the application system (such as APO) are installed.
Result
The log lcinit.log is displayed.
If an error occurs during the initialization, the initialization process is terminated and the system immediately displays the current lcinit.log.
A terminated initialization attempt means that the corresponding liveCache database instance is not executable. Eliminate the error and restart the initialization process.
The initialization of the liveCache database instance is also logged in the system log of your SAP system (transaction SM21).
