livecache 7.5 homogeneous copy to already existing maxdb 7.5

I am trying to do homogeneous copy of scm4.1 system which has livecache into a system where maxdb 7.6(for content server) is already there. Can somebody suggest what changes are required for such situation.

original server:

dbmcli>version

OK

version,os,dbroot,logon,code,swap

"7.5.0","UNIX","/sapdb/TLX/db",True,ASCII,1

    Hello Anantha Papagiri,

    -> Please review the SAP notes for the Homogenous copy of the liveCache &&

    System Landscape Copy for SAP SCM :

    457425 Homogenous liveCache copy using backup/restore

    877203 Post steps after the Homogenous liveCache copy

    886103 System Landscape Copy for SAP SCM

    ->"to do homogeneous copy of scm4.1 system which has livecache into a system where maxdb 7.6(for content server) is already there."

    What do you mean? You could run the System copy SCM 4.1 to SCM 4.1 & the content server is running by himself. And if you need, you could run the content server copy too using the SAP note::

    129352 Homogeneous system copy with MaxDB (SAP DB)

    < SAP note:: 1014782 FAQ: MaxDB system copy >

    Thank you and best regards, Natalia Khlopina

      Hello Giridhara Tadikonda,

      If I understood you correctly, the target system and the target liveCache instance

      will be installed on the server, where you have installed/run the Content server

      with database instance of the version 7.6.

      In general you could have two or more MAXDB database instances of the different

      Versions running on the same server, if you have enough OS resources on the server

      < memory, CPU … >.

      See the SAP note:

      327578 New software structure as of SAP DB version 7.2.4

      &&

      links :

      http://maxdb.sap.com/currentdoc/44/118d969c471a75e10000000a1553f6/content.htm

      http://maxdb.sap.com/currentdoc/87/dba841c0dae234e10000000a1550b0/content.htm

      As you know the independent database software is downward compatible.

      For the installation of the SCM 4.1 or liveCache please follow the SCM 4.1 & liveCache

      Installation guides.

      First, please review the liveCache homepage at https://www.sdn.sap.com/irj/sdn/livecache

      Release-Dependent: SCM 4.1 ->

      "Matrix of released OS platforms for SCM 4.1 - SAP liveCache Technology 7.5.0"

      Please pay attention that to do the homogeneous liveCache copy you should have the

      same OS on the source & target servers.

      < See SAP note::

      457425 Homogenous liveCache copy using backup/restore >

      Otherwise follow the SAP note 632357

      Thank you and best regards, Natalia Khlopina

    With version 7.6 I understand from the note 979401: Adaptive computing with MaxDB/LiveCache can be used and the process is simplified. I am working on this method.

      Hello Giridhara, Sorry for the delay.

      A) As I understood after you run the last step (point 3) of the note 457425,

      you are able to connect to the liveCache with superdba user &

      in DBMGUI :: Instance -> Configuration -> Database Administrators,

      you could see now two users control & superdba.

      After you run::

      dbmcli -d <database_name> -u <dbm_user>,<password> load_systab -u <sysdba_user>,<password> -ud <domain_user_password>

      ( the loading system tables could be done, when livecache is in 'online'

      Or 'warm' mode. )

      => the upc files were maintained with the superdba, domain users data.

      =>

      You will see 3 users with the command:

      dbmcli -d <database_name> -u <dbm_user>,<password> user_getall

      B) The SAPR3 user is the standard liveCache user, it's SQL user & you should be able to connect to the database using SQLStudio of dbmcli command::

      dbmcli -d <database_name> -u control,<password>

      <enter>

      dbmcli on <database_name> >sql_connect sapr3,<sapr3-pwd>

      <enter>

      dbmcli on <database_name> >sql_release

      dbmcli on <database_name> >exit

      C) Please review the SAP note 877203.

      D) "Brief description of the user types'" in database is available in the SAP note 25591

      && see the documentation at

      http://maxdb.sap.com/currentdoc/default.htm -> Basic Information

      -> Glossary -> User ->

      < -> See also: Concepts of the Database System, Users, Authentication and Authorizations < -> Changing the Passwords of Standard Users > >

      Thank you and best regards, Natalia Khlopina
