Initializing liveCacheLocate this document in the navigation structure

Prerequisites

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

Context

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

Note

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

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.

Procedure

  • Initialization with the DBA Cockpit

    Open DBA Cockpit (transaction DBACOCKPIT).

    The display options in DBA Cockpit vary depending on which SAP NetWeaver release you are using.

    • Choose Start of the navigation path Current Status Next navigation step Properties and Operating Next navigation step Edit Next navigation step Initialize liveCache End of the navigation path.

    • SAP NetWeaver 7.1: Choose Start of the navigation path Properties Next navigation step Edit Next navigation step Initialize liveCache End of the navigation path.

  • 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 Start of the navigation path liveCache Next navigation step Monitoring End of the navigation path.

    4. Choose Start of the navigation path Administration Next navigation step  Operating End of the navigation path.

    5. Choose Start of the navigation path Administration Next navigation step Initialize liveCache End of the navigation path.

  • 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 data such as the name of the database connection.

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

  • 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 operational state ONLINE or ADMIN, it is transferred to the OFFLINE operational state.

    2. The SAP liveCache database is then transferred to the operational state ADMIN 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.

Results

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. You will find an overview of liveCache operating in the DBA Cockpit in the user menu Properties.

Caution

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

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