How to Initialize LiveCache

[Former Member]

Hi Team,

We are on SCM 7.02 connected with LiveCache 7.9.

We need to initialize LiveCache, I need to know required pre and post Steps of this Initialization Activity.

I performed Initialization by MaxDB Studio on LiveCache and Start Facing below Issue when trying to connect LiveCache with SCM in LC10 -

283 DBMSrv   Command 'user_sap ...' is being executed.

2013-10-11 15:30:23       1254 ERR     -24949 DBMSrv   ERR_USREXISTS: User name already exists

2013-10-11 15:30:23       1254 ERR     -24580 DBMSrv   ERR_COMMAND_FAILED: Command 'user_sap' has ended and failed with return code -24949.

2013-10-11 15:30:48       4828 INF        421 DBMSrv   Command 'user_get ...' was executed since 2013-10-11 15:30:48.

2013-10-11 15:30:48       4828 ERR     -24935 DBMSrv   ERR_NOUSERS: no users found

2013-10-11 15:30:48       4828 ERR     -24580 DBMSrv   ERR_COMMAND_FAILED: Command 'user_get' has ended and failed with return code -24935.

Before Initialization, LiveCache was working fine.

So I am expecting we have few activities which should be done as post step or pre-step for LiveCache initialization to resolve this issue.

Can you please suggest.

Hello Shivan,

when you initialize the liveCache in MAXDB studio, the liveCache liveCache data and log volumes will be reformated by liveCache kernel and the liveCache will be empty with reloaded system tables, and will not have the schemas users. You initialize the liveCache in MAXDB studio for restore, for example.

Please review the SAP note 640107 for more details. Please read the note with attention to avoid the data lost.

When you initialize the liveCache in LC10 using LCA connection, the lcinit script will be called with init & the post-inititialization steps will be run as well. After the liveCache will be initialized by liveCache kernel, restarted online, the system tables reloaded, the liveCache user will be created & liveCache routines will be registered as well. You could see all actions perfirmed in lcinit.log & lcinit.his files.

Then post-initialization report will be runiing, which set for LCA connection in the reports tab.

Please be careful to initialize the liveCache. Discuss with your team & select the correct action according your plan-project. Please create the message to component BC-DB-LCA or BC-DB-LVC if something is NOT clear on how to initialize the liveCache.
