Dear All,
I am planning to make a standy server for Livecache for my SCM system.
Server Details is as follows:
Scm : SAP SCM 5.10
Lc version :KERNEL 7.7.04 BUILD 037-123-218-794
DBM Server : DBMServer 7.7.04 Build 037-123-218-794
O/s : AIX
Database : Oracle 10.2.0.4.0
Everyday Im taking a complete Data backup via db13.
My standby server has been configured with the same file system as of SCm and livecache.
Please guide me as what are my pre-requisites inorder to do a restore at standby livecache server and what kind of backup is needed in primary site inorder to restore at standby.
Thanks and regards,
Kiran
hello,
Just like to add some references that can help:
1. From 7.7 online doc: Standby Database -
http://maxdb.sap.com/doc/7_7/44/d7b0ca22873ee1e10000000a114a6b/frameset.htm
At the end of this page, there's a reference to a tutorial called "Setting Up and Updating Standby Databases"
2. SAP note 952783: FAQ: MaxDB high availability (also applicable to LC)
pt 3. Which mechanisms does MaxDB offer to minimize downtimes?
=> Shadow database (standby database)
3. http://wiki.sdn.sap.com/wiki/display/MaxDB/HowTo-StandbyDBlog+shipping
=> "how to setup a standby database with automatic log shipping for MaxDB, livecache .."
4. General LC online doc:
http://help.sap.com/saphelp_nw70/helpdata/EN/0b/1c5244486a994e8fc69d1894a11d93/frameset.htm

Thank you all for your prompt replies.
Currently Im taking complete data backup of Live cache server everyday.
Also auto Log save mode is on.
During restore/recovery, is the compete data backup sufficient? or is it required that I carry out redo-log back up everyday to restore the most current data?
Also from transaction LC10 Im not able to connect to database manager GUI.Pls help me in this area too.
Thanks and Regards,
kiran
Hello Kiran,
1. Itu2019s dependent on the problem you are going to solve and on your project.
For example, the complete data backup of the source liveCache made in sync with SCM system database backup will be sufficient for restore/recovery to do a System copy.
See SAP notes:
886103 System Landscape Copy for SAP SCM
457425 Homogenous liveCache copy using backup/restore
If you lost the data or log volumes, for example, you must execute a recovery with initialization using the last successful data backup, assumed you have it, and all of the following log backups. In this case, the loss of data includes the period as of the last log backup.
To avoid the data loss please see the recommendations in the SAP note 869267, answer on question 3.
< What do I need to pay attention to when configuring the log with MaxDB?>
Please review the SAP notes:
869267 FAQ: SAP MaxDB LOG area
1377148 FAQ: SAP MaxDB backup/recovery
2. u201CAlso from transaction LC10 Im not able to connect to database manager GUI.u201D
Itu2019s better to create another thread at forum for each problem.
Could you please provide more information to get clear on the last reported issue::
The DBMGUI should be installed and could be started on the same host where the SAPGUI runs.
- How did you install DBMGUI on your PC?
SAP Note :: 386714 SQL Studio + Database Manager GUI installation
- What is the version of the DBMGUI?
( For example, you could find the answer, when you start the
DATABASE Manager -> Go to the HELP-> About Database Manager )
- What is the version and SP of the SAP Basis on your system?
- What error did you get, when you tried to connect to the liveCache using DBMGUI in LC10?
Thank you and best regards, Natalia Khlopina
