CUA setup for a refreshed system copy
IF I copy a system that is under CUA, do I have to remove CUA first?
Or can I copy the system and on the target system, delete the CUA?
What is the best practice for system refreshed and CUA?
Thanks
Weyland
Hi,
Yes, you have to detach the CUA first, before starting with client copy to avoid inconsitency..
Like Client Copy profile includes User Master Records from the source client (SAP_ALL or SAP_USER profile), you should deactivate CUA in the target client.Otherwise, the users in the target client will remain untouched. If you
don't need to copy the User Masters from the source, use a client copy profile that excludes User Master Records,
Also check the pending Idocs to be processed in target client before detaching from CUA. Correct the logical system name and RFC after system copy to make it again functional with CUA.
Cheers

Precautions for performing a system copy
Respected Guru's
I have to perform a system copy, should i reconfigure STMS after the copy.
Should i follow any precautions before performing a system copy in
STMS.
Thanks and Regards,
Dayanandan.Hi,
As such there is no precautions related to STMS but yes after system copy you need to reconfigure your STMS.

Hi,
We would be going for a SLT refersh from production to Acceptance.
Please do share any documents related to this.
Thanks,
RajivHi Rajiv,
Early last year I discussed with my customer approaches how such a refresh could be realized and what needs to be considered.
I can share my thoughts with you, however I have to emphasize that we never tested the procedures in detail. And in nowadays versions of SLT some transactions might be different.
So please keep them as a hint but not as a guideline.
How-to refresh QAS from PRD in SLT scenario?
Landscape:
Production landscape consist of ERP-system PRD, with replication to HANA-database HAP via SLT-server SLP
Quality landscape consist of ERP-system QAS, with replication to HANA-database HAQ via SLT-server SLQ
Scenario:
QAS system should be refreshed with recent PRD data
Approaches:
A. Refresh QAS from PRD, clean HAQ, repeat replication
B. Refresh QAS from PRD, HAQ from HAP and SLQ from SLP
A. Detailed steps for approach A: Refresh + repeat replication
** not tested **
1. Backup PRD
2. Stop the master replication job in HAQ (transaction LTR -> jobs tab -> Edit -> Stop)
3. Refresh QAS from ERP backup
4. Clean up old replication
a. Delete old configuration in HAQ (transaction LTR)
b. Delete triggers in refreshed QAS system
i. Call transaction IUUC_REMOTE à Expert Functions à Delete Triggers à Enter the names of the replicated tables à Execute
If step i. is successful, continue with step c., otherwise go on with next step ii.-iv.
ii. Determine all triggers
iii. Execute function module DB_DROP_TRIG in transaction SE37 for every trigger (specify EXEC = X, TABNAME = tabname and TRIG_NAME = trigger name)
iv. Verify that no triggers remain
Alternative: You can also write a sqlscript for all tables/triggers and run it on db level
c. Delete logging tables in refreshed QAS system:
d. List all logging tables: transaction SE11, enter /1CADMC/* à press F4 key; then copy the logging table names to notepad; copy all names into the clipboard
i. Call transaction IUUC_REMOTE à Expert Functions à Delete Logging Tables à copy the trigger names from clipboard to the input selection à Execute
ii. Verify that all logging tables have been deleted (as in i.). It seems that the logging tables for DD02L and DD02T will still exist; in this case drop the two logging tables in DB level.
e. Cleanup SLT server HAQ:
i. IUUC_REPL_CONFIG: Should be empty
ii. IUUC_REPL_CONPAR: Should be empty
iii. IUUC_REPL_HDR Should be empty
iv. IUUC_REPL_MAP Should be empty
v. IUUC_RS_STATUS Should be empty
vi. IUUC_RS_ORDER Should be empty
vii. IUUC_TABLES Should be empty
viii. DMC_COBJ Should be empty
ix. DMC_MT_TABLES Should be empty
x. IUUC_LOGTAB_ID Will be filled, so delete the entries with transaction SE16
xi. DMC_STRUC_ID Will be filled, so delete the entries with transaction SE16
xii. DMC_ACT_REC Will be filled, so delete the entries with transaction SE16
xiii. Run report DMC_CLEANUP_USAGE in transaction SE38 with flag ‘delete all kinds of zombies’
xiv. Run report DMC_CLEANUP_USAGE in transaction SE38 with flag ‘delete all kinds of zombies’ and subproject = ZIUUC_<MTID> with <MTID> is the name of the mass transfer id of the configuration
xv. DMC_MT_HEADER Will be filled, so delete the entries with transaction SE16
f. HANA Studio connect with SYSTEM user to HAQ, go to Catalog > Authorization > Users and delete the user of the replication (cascade option)
5. Setup new configuration in SLQ
a. Check RFC connection in transaction SM59 from SLQ to QAS
b. Transaction LTR: Create new configuration
c. In the studio, check schema created in HAQ
d. In the studio, data provisioning, verify that tables DD02L, DD02T and DD08L are replicated
e. Prepare a text file with all tables to be replicated
f. In the studio, data provisioning, load the text file and add the tables to the replication
B. Detailed steps for approach B: Consistent Refresh all Systems
** not tested **
1. Backup all systems
a. Stop the master replication job in HAP (transaction LTR -> jobs tab -> Edit -> Stop)
b. Backup first PRD, then HAP and finally SLP
c. Start the master replication job in HAP again (transaction LTR)
2. Refresh QAS from ERP backup, no BDLS
3. Refresh HAQ from HAP backup
4. Refresh SLQ from SLP backup
5. Adapt SLT configuration, i.e. RFC connection to QAS in SLQ
6. Adopt hana server name in SLT configuration(/LTR), can be done inside db connection to HANA(/DBCO)
7. Update table “SYS_REPL”.”RS_REPLICATION_COMPONENTS” in hana and change the server name and configuration for the SLT replications.
8. Start the master replication job in HAQ again (transaction LTR)
9. Run BDLS in QAS to change logical system name (SLT will replicate the changes to HANA)

Export for system copy fails - Error 9 (Bad file number)
Hello all,
I am attempting to perform the export phase for a hetergenous system copy on our BI system (BI 7.0 - NW2004s). This system runs on HP-UX 11.11 using Oracle 10.2.0.2 and will be migrated to Windows Server 2003 and MS SQL Server 2005, once the export is complete.
While running sapinst to export the data from the source system, there are several input dialog screens that are skipped, which means I am not able to enter all the paramters used for the export. After seeing this behavior from sapinst, I reviewed the sapinst.log and sapinst_dev.log files and find the warning/error "System call failed. Error 9 (Bad file number)". I have included a portion of these files below.
I have reviewed notes 546006 and 583861, but these seem to refer to an Oracle error ORA-27121, but I am not receiving any Oracle errors in sapinst.log or the Oracle alert log. I have looked for possible permission or ownership problems with any of the SAP or Oracle files, but have not found any that were incorrect. Also, these errors do not specify which file sapinst is having problems with, so I do not have a specific file or area to check.
If anyone has seen something similar to this and has any suggestions, I would greatly appreciate any help.

Regards,
Rusty RobbinsHello Peter,
Thanks for the reply. I did confirm the points you made, and have the details below.
1. check filesystem, if you have enough space, especially /tmp
All filesystems have available space, and /tmp has 310 MB available, before the start of sapinst.
2. check again alert log, trace log for Oracle,
I could not find any errors in the alert_SID.log or any unusual trace files.
3. How did you run sapinst? Are you using "root" account.
I am running sapinst as user root and I am following all the recomendations in the system copy guide (at least as far as I can tell. ;p )
We have four BI systems in this landscape, and the other three have migrated successfully. The procedure I am using, is the same as for the other 3 systems and uses the same SAP media directory that was used on the other systems.
One other item that may be part of my problem here, is that this system is the production system, and was originally installed as a high-availability system, using HP-UX Service Guard for clustering. Currently, this system does not have fail-over enabled, but of course the cluster is still intact. One required piece of the Service Guard enviornment is the use of a virtual hostname. This seems to resolve successfully by sapinst, as I see the correct (virtual) hostname referenced several times. While this is a clustered system (for fail-over purposes), the CI and DB are installed on the same host. So it is not a distributed system, and if failover had been initiated, it would fail both the CI and DB instance, which is the same and only SAP instance.
This did raise one question in my mind, however. I am attempting to extract this using the following menu path within sapinst.
SAP NetWeaver 7.0 Support Release 3 --> Software Life-Cycle Options --> System Copy --> Oracle --> Source System Export --> Central System --> Based on AS ABAP and AS Java
Since this does use Service Guard, but is not a distributed system, should I be using a different path in the sapinst tree, for the export? I have only performed a migration using the above path, so I am not familar with the detailf of the other types, such as High-Availabitly or Distributed-System.

Downtime for Heterogeneous System Copy Export of Source DB2 LUW
Hello,
What is the downtime required for a heterogeneous system copy export of a source database on AIX with DB2 LUW? Here are the following details of the data itself:
DB size: 120 GB used of 240 GB.
Physical server: IBM Power5 quad-core 1.65GHz virtualized
RAM: 9.5GB> What is the downtime required for a heterogeneous system copy export of a source database on AIX with DB2 LUW? Here are the following details of the data itself:
I suggest you just "try it out" as a test run. It's quite impossible to give estimates based on database sizes. It's possible to migrate roughly 1 TB/hour with appropriate hardware, mostly your harddisks will be the bottleneck.
There are also a number of other factors like number of R3load processes, table splitting or not, parallel export/import etc.
I highly suggest to run the migration a few times before you do the "live" migration.

Which master DVD for system copy ?
Hi
If you have a Nw7.0 SR1 installation that has since been patched to be the same or higher level than SR2 - which master DVD should be used for a homegeneous system copy ? SR1 or SR2 ?
SR2 seems logical, but then you need also the DVD's (java etc) for SR2 which you normally wouldn't have around...Hi Per,
I will go ahead with the SR1 ones... when you do a Homogenoues System Copy you basically are installing a new system and then moving the database with all the patches from the source system.

DR setup for EP7 on Windows+Oracle
Hi,
We are in the process of DR setup for our portal system based on NW2004s, Windows 2003 and Oracle 10.2.
We are thinking of using oracle standby database with log shipping to keep the portal databases in sync on the primary and DR site. We are planning to do the following.
_Primary site:_
EP 7.0 installed on MSCS cluster
_DR site:_
EP 7.0 created as a copy of Primary via sapinst, non-clustered. The database will be refreshed from the Primary site DR and will be put in standby mode. Log shipping & apply will be configured.
Now if any apps are applied via SDM on the Primary site, will that be replicated via log shipping on the DR site? What about .par files deployed on the Primary site? Any way to keep the OS level files in sync provided these do not contain the hostname?
Do you see any issue with this setup? Has anybody done something similar?
The only reason we want to keep the database in sync on both the sites is because our users are in the j2ee UME and the user information including password needs to be retained on the DR site. The UME can't be moved due to our infrastructure setup.
Is there any way we can keep the UME content, user details/password in sync between 2 j2ee systems? If there is a way, then we don't need to setup the standby database.
Any help is welcome.
regards,
MohanHello,
We have installed DB/SCS on external disks which are part of the cluster resources. Oracle / SCS disks are replicated onto mirror disks by SRDF replication. So Oracle/SCS have no issues in a DR environment, although there is downtime while services are being started up on DR. The app servers connect to the DB/SCS using aliases , so we just the change the DNS of the alias to point to the DR server before restarting application servers. We have never had trouble with application deployed on production environment. They always reflect on DR.
However, because the DR application servers are installed as dialog instances of the same instance, we do not have access to CI (and hence SDM, VA, Config Tool) in a DR environment. I wanted to know if there is a way to set up the Central Instance so that it is available in DR as well.
thanks,

Hi,
I am very new to SAP BASIS, can any one please send any link or some basic information which is needed for homogeneous system copy for windows, ECC 6.0 & IBM DB2.
Thanks in Advance
biplabHi,
The short explanation is that a system refresh is when you take the data (database) from your production system and refresh/replace your QA database with that, so at the end of the day you have new data on QA.

Homogeneous System Copy - Help me
Hi,
I need to refresh the Training environment with the QAS environment data then I did the client copy from QRP(QAS environment) to TRN (training environment). This copy was made successfully, but with some data inconsistences.
And then a decided to do a Homogeneous System Copy.
I did the HSC selecting the option "Standard System Copy/Migration (R3Load-Based) " but exist the another option "System Copy / Oracle Backup/Restore".
And my doubt is: the process that I need to do is the Standard System Copy / Migration (R3Load-Based) or System Copy / Oracle Backup/Restore?
And the inverse process (import), can I to install just a Database Instance, once that a Central Instance already exists?!
Thanks and Regards,
Dany AndersonHii the process you need to do is system copy . In system copy there are two ways one by using R3load tool and other is backup method. Generally the backup method is faster where all your database will be backedup and copied to the target system. R3load and oracle backup are just two methods of doing system copy.
homogeneous system copy if your target system is on the same operating system and database system as your source system. The database contents are copied from the source system to the target system.
You perform a heterogeneous system copy if you want to change the operating system or database system. Migration is another term for a heterogeneous system copy.

Hello All,
One of our IT partners has got an SAP SRM implementation and we need to set up our own SRM system as a copy of the partner's SRM system.
How can we do this? What system copy approach we can follow?Will DB restore work?
During the copy will it ask for any hardware/software keys?
Do we need to seperately buy the licenses ?
Our OS/DB is going to be different from that of the partner.
Please give me a high level idea.

System Refresh
How can we do this? What system copy approach we can follow?Will DB restore work?
You can do this by homogeneous system copy. Yes DB restore method will work.
During the copy will it ask for any hardware/software keys?
No it will not ask for any keys(Homogeneous system copy not sure about heterogeneous system copy)
Do we need to separately buy the licenses ?
No
Our OS/DB is going to be different from that of the partner
The copy of an SAP system to another hardware is called a system copy. If the target system will run on a different operating system (OS) and/or a different database system (DB) than the source system, then this is called a heterogeneous system copy or OS/DB migration. Check below link for detail
https://websmp108.sap-ag.de/osdbmigration
Note 82478 - SAP system OS/DB migration
You can download system copy guide from below link
https://websmp203.sap-ag.de/instguides.
Homogeneous System Copy:-During the system copy you use the same operating system and database platform as the original
system.
Heterogeneous System Copy:-During the system copy, you change either the operating system or the database system, or both.
Heterogeneous system copy is a synonym for migration.
System Copy :-Duplication of an SAP system. Certain SAP parameters might change in a copy. When you
perform a system copy, SAPinst installs all the instances again, but it uses a copy of the source
system database to set up the database.
Database Copy :-Database-dependent part of the system copy.
Hope this helps
