How to rebuild a livecache?

Dear Gurus:

We get the requirement to rebuild a livecache for clients.

Could you direct me to some blogs since I am new in this area? Thanks!

Hello Linda Li ,

1) The helpful links to start:

www.sdn.sap.com/irj/sdn/livecache

< It has also link to Best Practices for Solution Management: mySAP SCM , review the documents. >

and SAP link:

service.sap.com/scm -> Technology

2) Please ask more details about your project ::

• The version of the system;

• The liveCache version;

• Do you need to build the new system?

• Do you need to create the System copy?

• The liveCache data are corrupted & the backup/recovery is not possible.

• What liveCache application did you run < or will run > on the system.

3) Also review the SAP notes::

886103 System Landscape Copy for SAP SCM

457425 Homogenous liveCache copy using backup/restore

632357 Backing up liveCache data for SCM 4.0 or higher

Thanks!

Here is the info we have:

The LC is of version 7.5.

We want to

1) test DR for LC, and

2) clone an LC to another LC name.

Please help more.

Thanks again,

Hello Linda,

1) test DR for LC, and

< I assumed, that DR is Disaster Recovery >

-> Please review the SAP notes:

1377148 FAQ: SAP MaxDB backup/recovery

952783 FAQ: MaxDB high availability

820824 FAQ: SAP MaxDB/liveCache technology

-> Please see the document "Backup and Recovery for SAP APO (3.x) / mySAP SCM (4.x)" at

http://www.sdn.sap.com/irj/sdn/livecache

< go to Best Practices for Solution Management: mySAP SCM >

-> Please explain more detailed, what kind of a disaster you think of?

Then we could think about the liveCache recovery plan.

2) "clone an LC to another LC name."

I assumed, that you need to create the clone of the liveCache instance,

the target liveCache will have the different liveCache name.

Please follow the notes:

for Homogenous liveCache copy ::

457425 Homogenous liveCache copy using backup/restore

for Heterogeneous liveCache copy ::

632357 Backing up liveCache data for SCM 4.0 or higher

Please see documents in the Maxdb wiki at http://wiki.sdn.sap.com/wiki/display/MaxDB/Main

< go to SAP MaxDB HowTo then section "Backup / Recovery" >, one of the documents is

"HowTo - Creating a clone of a SAP MaxDB database".

Thank you and best regards, Natalia Khlopina

Thanks a lot!

BTW, how useful is the SAP-Press book on MAXDB ? I am considering to buy one. Thanks!
