1. Preparations:

   ======================

• Use the relevant SAP Note to check the operating system prerequisites: 919224 System
• Requirement Windows X64 MaxDB/liveCache 7.x.
• For our environment we have to Implement SAP Note 2591536 in our SCM system to apply latest patch. This SAP Notes has some perquisites SAP Notes as well which needs to be implemented. Below is the Sequence of SAP Notes implemented in our SAP environment prior to the Upgrade. Implement the SAP Notes using SNOTE T-Code in  below sequence.

• Log on to the SAP Software Download Center to download the target LCA package.

• Check Current Version of LiveCache in SAP using LCA13 T-Code

1. Import the new version:

=================================

• Switch to a temporary directory (for example, C:\temp).
• Unpack the SAR package in the temporary directory:

SAPCAR -xvf <file_name>.SAR

• Before importing the software, stop the SAP liveCache with the liveCache assistant (transaction LC10).

• Stop the SAP system & its Services at OS level, since this retains RFC connections to the SAP liveCache kernel (alert monitor in LC10) that cause the program DBMRFC to be executed even if all SAP liveCache database and tools have been exited.
• Login at OS level with <SID>ADM user
• Open a command prompt and call the tool SDBUPD in the created directory lca100<LCA_build>_livecache-<os>-64bit-<arch>-<build>. Hit below command

          SDBUPD -d <liveCache_name> -u <dbm_operator>,<password> -update_global

(for example: SDBUPD -d LC1 -u control,control -update_global)

• Below screen pops-up

• After the update the above screen exists
• You can check your installation/update logs in SDBUPDMsg*.log files placed at path <LCA Setup Drive>:\sapdb\data\wrk

• Update completed successfully
• Bring up SAP services and applications.
• Bring up the SAP and Livecache using LC10 T-code.

• Verify the Updated LC versions using LCA13 T-Code

Note: Use LCA build update package to patch and not MaxDB. MaxDB will be updated automatically afterwards.
