Procedure documentationInitializing liveCache Locate this document in the navigation structure

 

In the Operating user menu, you can, among other things, initialize an SAP liveCache database.

Note Note

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

End of the note.

An SAP liveCache database is initialized by the Database Manager. The DBM Server executes the control file lcinit.bat with the option init. After the SAP liveCache database 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 SAP liveCache caches once the SAP liveCache database has started up. Rather, all data must be newly built up. Among other things, the liveCache applications are also registered. For this reason, each initialization process can take some time.

Prerequisites

In accordance with the authorization concept, the user has been assigned the role SAP_BC_LVC_SUPERUSER.

Procedure

Initialization with the DBA Cockpit

Open the DBA Cockpit (transaction DBACOCKPIT) and choose   Properties   Edit   Initialize liveCache  .

Initialization with the liveCache Assistant

  1. In the user menu, choose liveCache Assistant (transaction LC10).

  2. Enter the name of the database connection. You can select the name from the list of existing names. You can restrict the search for the required name.

  3. Choose   liveCache   Monitoring  .

  4. Choose   Administration   Operating  .

  5. Choose   Administration   Initialize liveCache  .

Initialization in the Background

  1. Choose ABAP Editor (transaction SE38).

  2. Enter the report name RSLVCINIT.

  3. Create a variant of the report. You must enter the name of the database connection, among other things.

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

Initialization from the Operating System Level

Function Module for Starting/Stopping/Initializing

Process Flow

  1. The operational state of the SAP liveCache database instance is checked. If the SAP liveCache database is in the ONLINE or ADMIN operational states, it is transferred to the OFFLINE operational state.

  2. The SAP liveCache database 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 SAP SCM) are installed.

Result

The lcinit.log log is displayed. If an error occurs during the initialization, the initialization process is terminated and the system immediately displays the current lcinit.log. You will find an overview of liveCache operating in the DBA Cockpit in the user menu Properties.

Caution Caution

A terminated initialization attempt means that the corresponding SAP liveCache database is not runnable. Eliminate the error and restart the initialization process.

End of the caution.

The initialization of the SAP liveCache database is also logged in the system log of your SAP system (transaction SM21).
