LiveCache Homogeneous Copy

Hello,
We are doing an homogeneous copy of our productive SCM 5.0 system onto the QA system. I'm kind of stuck with the LiveCache part.
Our LiveCache Version is 7.6.03.12 on both systems. Our Productive LiveCache is bigger than the QA one. So we have:
PRD : CACHE_SIZE = 3750000 and 6 volumes of 10Gb each
QUA : CACHE_SIZE= 750000 and 6 volumes one 1Gb each
The actual complete dump of our productive LC system is only 600MB. I tried to load it onto the QUA LC system but it won't let me.
I have checked sap note 457425 but if i try the part 1 of the note that says to recreate the LC instance, when i enter the name of the instance, it tells me that it already exist and doesn't go further.
If i skip the first part and go directly to the restore part, it does the restore, but i can't restart the instance (the last step of the recovery wizards says : "the database instance is not yet restartable. Choose back to perform another recovery action or choose close to end the recovery wizard".
If i try to restore a backup of the QA LC system, it works well ...
What is it i'm doing wrong ? Do both instances have to be configured equally for it to work ?
Thanks for your help.
Y.

Thanks Natalia !!!! that did the trick
i had to run the command :
dbmcli -d LC1 -u control,password load_systab -u superdba,password
and then i was able to start it from LC10.
Thanks a lot for your help !!!

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 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 > >

No username of Source system is avbl after livecache system copy

Hi Experts
I have done a livecache system copy from the source system to target system. Here the steps are
Assume my Source SYstem Livecache is RP1 and Target System livecache is RS1.
1. Taken Source system livecache DATA and LOG Area backup RP1.
2. Defined the same source system backup medium name in Target System (RS1 and moving the Source system Liveacache backuped files to Target system and defined the medium name as per that)
3. put the livecache db_admin mode
4. db_activate RECOVER <medium_name>.
5. recover_start <log_medium_name> LOG <nnn>
6. db_online.
Here we faced that
ERR
-24622,ERR_AUTOLOADSYSTAB: Automatic loading of the System Tables failed
-24907,ERR_DBAWRONG: Wrong database system administrator
-24988,ERR_SQL: SQL error
-4008,Unknown user name/password combination
So we activated the SUPERDBA as " db_activate SUPERDBA,<password>
then it came to online. and afterwards we have used the load_systab command to load the tables.
BUT we could not find any Source System name like "RP1ADM" in the tables of the livecache database. Only there are CONTROL,SUPERDBA username availbale. Usually there will be also the source admin name . I dont know why it is missing
Before a month we have done livecahe restore same as now in that time we got the source system name admin also. ( RP1ADM) and also tables which owned by RP1ADM. alos i could find APPSYSPARAM table and the instance also registered.
But now in this restore we could not find the above.
We followed the same procedure and there is no change in the steps also.
Could anyone help me...
Regards

Hello Bala,
1. As I wrote you already, the notes:
886103 System Landscape Copy for SAP SCM
877203     Post steps after the Homogenous liveCache copy using backup/
457425     Homogenous liveCache copy using backup/restore
has all recommended steps to do, when you will run the u201CSystem Landscape Copy for SAP SCMu201D
2. If you run the u201CHomogenous liveCache copy using backup/restoreu201D you should pay attention to the note 457425. After you imported the complete data backup < step 2. > you need to update the system tables.
To update the system tables you need to know the correct database SYSDBA user & password.
After you restored the databackup of the source database, start the database online & run u201Cselect * from usersu201D SQL command to see the SYSDBA user. Then check that you know the DBA user ( DataBase Administrator ) & password of the source database instance => Open the SQL session with this
user & password.
Example:
after db_activate recover <medium_name>
login as control,password
db_online
sql_execute select * from users
sql_connect superdba,<password of source system>
If you didnu2019t get error with the last command, then you could update the system tables with the superdba,<password of source system> using load_systab command.
The system tables will be updated & the correct SYSDBA user & password will be updated in *.UPC file.
3.
user_sysdba:
You make the database system administrator known to Database Manager. It is only necessary to use this DBM command if the database administrator is not known or is incorrectly known to Database Manager.
u201CI have tried like this
after db_activate recover <medium_name>
login as control,password
db_admin
user_sysdba superdba,<password of source system>
db_onlineu201D
You could update the .upc files with the wrong SYSDBA user password u2026
You was lucky, that you knew the correct SYSDBA user and password of the source database.
Example < NLK is my local database >:
A.     I could update the .upc file with wrong password of SYSDBA user:
dbmcli -d NLK -u control,control
dbmcli on NLK>user_sysdba superdba,test
OK
dbmcli on NLK>db_online
OK
dbmcli on NLK>load_systab
ERR
-24909,ERR_DBAUNKNOWN: SYSDBA unknown
dbmcli on NLK>exit
B. I could update the .upc file with wrong SYSDBA user:
dbmcli -d NLK -u control,control
dbmcli on NLK>user_sysdba test,test
OK
dbmcli on NLK> user_get test
OK
u2026
dbmcli on NLK>sql_connect test,test
ERR
-24988,ERR_SQL: SQL error
-4008,Unknown user name/password combination
dbmcli on NLK> dbmcli on NLK>sql_connect superdba,admin
OK
I could connect as test,test; but the test user is NOT SYSDBA user u2026
dbmcli -d NLK -u test,test
dbmcli on NLK>
Itu2019s recommended to user the load_systab command, so the .upc files will be updated with the correct SYSDBA user/password or
you will get error.
4. http://maxdb.sap.com/doc/7_7/86/68627a1bc642e6a6f73d3bc7a55fe1/content.htm
You got error:
ERR
-24622,ERR_AUTOLOADSYSTAB: Automatic loading of the System Tables failed
-24907,ERR_DBAWRONG: Wrong database system administrator
-24988,ERR_SQL: SQL error
-4008,Unknown user name/password combination
The automatically updating the system tables, according to the default value, is switched on.
After you will run the update system tables with the correct SYSDBA user & password the *.UPC file will be updated,
and with the next liveCache restart you will not get this error.
5. See more information in the MAXDB library:

Which is better Remote Client Copy or Homogenous copy

Hi All
I have a task to synchronize the ECC Production server with devlopment server
For this I have two option :
1. Remote client copy from Production to Development
2. Implementing homogenous copy(oracle procedure) of production server and then remove the existing development server.
I want to know your expert view with which one should I go with, as I have seen many times that whenever I do remote client copy it gives error in test phase the following tables error. so I am not sure wherther I just go with clent copy or not.
What things should keep in mind before doing it before doing homogenous copy?
Thankx in Advance
Regards
Vinay Paul

Hi All
Is there any solution for below if I decide to go with Oracle Procedure of system copy. Because we have to provide this to one of our client as there production and Development server are out of Sink.
1. Retaining the development history
2. Retaining the transports history.
I came to know that the above thing is possible but I have no idea how.
Thankx in advance

Homogeneous Copy / Converting Distributed System as Central System.

CURRENT SAP LANDSCAPE.
SAP Production System is installed as a Distributed System:
SAP Application Host:_ AIX 5.2 - SAP Application (Central Instance - Central Services) based on NW 7.0 - ERP 2005 SR1.
Database Host: AIX 5.2 - Oracle 10G ver 10.2.0.2.0. - Database remains in SAN (Storage Area Network)
ESCENARIO ONE:
COPYING ONLY CENTRAL INSTANCE AND CENTRAL SERVICES TO A NEW HOST.
Purpose: I want to copy only SAP Application (Central Instance an Central Services) to a new host and connect to my current Database Host .
According System Copy Guide (*) the concept of System Copy includes installation of SAP instances again using copy of source system database, likewise in this Guide I found the following restrictions:
Restrictions.
1.     Copying the database only is not supported!
2.     Copying the central instance only is not supported!
      The migration controller deletes all dialog instances in the database, so the
      system is not complete any longer.
3.     Reinstalling the central instance without the database is not supported!
      The migration controller deletes all dialog instances in the database, so the
      system is not complete anylonger
Questions:
1.     Using Homogeneus Copy (Abap+Java) can I copy ONLY SAP Instances (Central Instance and Central Services) to a new host without copying Database ?
2.     Which is the best procedure to follow for this purpose?
(*) System Copy for SAP Systems Based on SAP NetWeaver 2004s SR1 ABAP+Java
Document version: 1.1 ‒ 08/18/2006
ESCENARIO TWO:
CONVERTING DISTRIBUTED SYSTEM IN CENTRAL SYSTEM
Purpose: Convert our SAP Distributed System (two hosts) in SAP Central System (one host)
Questions:
1.     Using Homogeneous Copy (Abap+Java) can I copy SAP Instances (Central Instance, Central Services) and Oracle Database Instance to only one host (Central System) ?
2.     Is there any specific experience or procedure for this special case?
3. Can I restore Database Full Offline Backup and SAP Application Offline backup in the new server as an alternative ?
Thanks.

Use the distributed system option, as that is what applies to your target system. It is all explained clearly in the system copy guide, which you should definitely reference as appropriate for your software version: http://service.sap.com/instguides -> Installation & Upgrade Guides -> SAP NetWeaver -> SAP NetWeaver 7.4 (or version as appropriate) -> Installation -> 2 - Installation - SAP NetWeaver Systems -> System Copy: Systems Based on SAP NetWeaver 7.1 or Higher -> Windows: ABAP (or system variant as appropriate). In the guide, choose the Database-Specific System Copy: MS SQL Server-Specific Procedure. Also, be sure to check out the chapter on Copying the Database Only - Refresh. Basically, it says to run SWPM on the target database instance, choosing <Product> -> <Database> -> System Copy -> Target System -> <System_Variant> -> Based on AS ABAP (or other as appropriate) -> Database Refresh or Move.

Restoring clients after homogeneous copy

Hi...
I have a QAS system with three clients (100, 120 and 200).
I have a PRD system with just the client 100.
I was asked to perform an homogeneous copy from PRD to QAS, but to make sure clients 120 and 200 are not destroyed.
My question is:
Would a client export (SCC8) with profile SAP_RECO solve my problem?
I would first export both clients (120 and 200) with SAP_RECO, using the QAS system as the target, perform the copy, and then import the clients again through STMS. Would this work? Or is there any other way of doing this?
thanks
Antonio

Hi Antonio
If your are performing the system copy from PRD to QAS its will be comes only 100 client.
for this kindly follow the steps
1. Before starting the system copy Export the QAS client 120 & 200.
2. Perform the system copy from PRD to QAS, & Post system copy activitys
3. Create the New clients in QAS system
4. Do the Import which you already performed

Homogeneous copy

Hi,
I am doing a database migration from the existing Production to a new server with same OS,DB and SAP ERP version. The new server type is also same with more memoryand HDD resources. The OS is windows 2003 server, DB Oracle 10.2 G and ERP version is ECC 6.0. I am planning for an homogenous copy using sapinst. My plan is to export the database using sapinst from the current production server and import to the nerserver using sapinst. Pls clarify the following points before doing the the export/ import and help me to do this activity with out much issues.
1. What are prerequistes to be carried out before doing this activity.
2. While importing whether we have to create the central instance creation before importing the database.
3. What are post installation activities.
4. Is there any other better method to carry out the server migration.

Users on a new system (Homogeneous copy)

Hi people,
I have done a system copy (homogeneous) I do not know if the target system must be or not users who were at the source system, someone I can indicate what?
Thank you.
P.D: <removed_by_moderator>
Edited by: Julius Bussche on Jul 1, 2008 1:17 PM

Hi,
You can also export the user master from source system from one client and again import it in the target system using TP then you should be able to log into that client with the same username,password as of source system.
Example:
From Sourcesystem (PRD) export user master from client 200.(login used is abc and password is xxxx)
In the target import that user master in client 200 using Tp.
Then log into the taget system (QTS) client 200 using username abc and passowrd xxxx .
After this anyway yopu have to do the post activity like scc7.
Hope this helps.
Thanks.

Is Recovery possible after homogeneous copy

Hi all,
my database is oracle 9i
1.I have 20 days old backup.using this backup I created a new system(by homogeneous system copy).Can I recover database using offline redolog files up to today date?
Thanks in advance
Regards
nani

yes it is possible, but you may need to rename your offline redologs so that it contains the SID.
20 days of redologs is a lot. hopefully, you have all offline redologs available and hopefully, you do not have any corrupted files...
it is better to take daily backups.

How to execute a homogeneous copy on linux?

Dear all:
      I want to do a homogeneous system copy from old server to new server.The old server is a production system which os is linux and db is oracle.The new server has highly hardware(cpu,memory) which os is linux.So,I want the new(traget) system will be the same as old system include backgroud jobs,customizing cofigration and so on ,it will replace the old server as a production server for my business.
    Someone can tell me the procedure upon the homogeneous system copy and how to do it?Thanks!
    By the way,do this action whether need migration key or not?
                                                   Brian yuan

Deat Brian,
In new system where u r coping your production system.
Follow the Homosystem copy guide for Linux & relevan to your SAP Release.
You have two methods for copy
1) Backup restore
2) Export
You can go with export option which is safer.
Do export of database from source
& import the export in target using sapinst.
Before that set the kernel & relevant settings for linux.
in /etc/sysconf.

Hi Alberto,
I still think access to this file is not as it should be.
Can you open it from the windows host ?
Should it not be: /tmp/EXPHM/ABAP/DATA/SAPAPPL1_1_1.TOC ??
Another error is the DbSl Trace: SQL-Error -204 in function db_open
Is it the NT client that can not connect to the db2/400 DB?
Have you tried deleting the SQL packages?
And updating the target kernel lib?
Including R3load
What does any OS job log tell you?
Kind regards,
Paul Hoogendoorn

Steps for Homogeneous Copy Windows/MS SQL Server

Hi All,
I would like to get the steps/Procedure for performing a homogeneous system copy for a system that is sitting on Windows/SQL server. we have performed two upgrades on our current system and we have installed NetWeaver components.
what would be the best way of performing the system copy?
Could you please assist with the steps to follow and the documentation

Hi Juan,
how can you assist when the scenarios then change to the following
The configuration was carriedout on SAP version 4.7 during the 1st phase of the
implementation, using a temporary server which hosts the Dev, Prod and Database.
The 2nd phase which is coming up will involve the following activities:
   Installation of SAP ERP 2005 SR1 on the new servers (prod and Dev)
   Installation of SQL Server 2005 on the thir server
   Migration of the existing configuration data on SAP 4.7 to the new PROD and DEV
servers running SAP ERP 2005 SR1
what would be the best way to carryout this exercise?
1. install ERP 2005 and the with the help of the Functional consultants use the migration workbench
2. do a system copy, then upgrade the 4.7 to ECC 6.0
