7.8.01.18 - R3szchk needs hours (homogeneous copy)

During an R3load export (Maxdb --> MaxDB) the R3szchk runtime is way too long, it needs almost 2,5 hours to estimate the tables sizes although it uses the database specific method:

I would understand that runtim if the dictionary method would be used - but I see no reason why the DB method is taking that long.
x_cons reports on UKT as "running" for all that time so there's no I/O taking place.

Running a PC via my Mac. Would I need a second copy of Word?

Hello!
So I am needing to get Windows running on my Mac for a specific PC only App called Nvivo.
I am looking into the Fusion vs Parallel issue which both have their advantages and disadvantages. However, I need to know if I need a second copy of Word (ie a PC version) to read the information from my Mac word files then to be read by Nvivo on the PC side (for the cross-platform pollination to work)?
Does Parallels of Fusion have a feature that makes it so only one copy of word is required? (Sounds like wishful thinking I know!)
Any help would be appreciated.
Thanks!

Hi,
all Word versions are Operating System - dependent.
An OSX Word won't work when running WIndows and vice versa.
But maybe the free OpenOffice will suffice for your needs in Windows.

If you are referring to the original system reinstall discs that shipped with every Mac before Lion came out you'll need to contact Apple with the serial # of your Mac and order a replacement set of them.
Or look on one of the Auction websites or places like iFixit.com for a replacement set.
If your Mac came new with any of the Download Only versions of OS X, Lion, Mt Lion or Mavericks you don't need any discs to reinstall OS X. You use the Online Internet Recovery system or the built in Recovery HD partition inb the internal hard drive.
For the built in Recovery HD hold down the Command + r keys at startup. For the Online system hold down the Command + Option/Alt + r keys and keep them held down until you see a globe on the screen.

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
Regards

Which EM files need to be copied ?

Hi,
In order to start the dbconsole on another server to access the same database, I copied the folowing files:
$ORACLE_HOME/<hostname>_<ORACLE_SID>
$ORACLE_HOME/oc4j/j2ee/OC4J_DBConsole_<hostname>_<ORACLE_SID>
$ORACLE_HOME/install/portlist.ini
So far, it works...
Do you know any other files that I should copy as well ?
Thanks
JD
Why am I doing this ?
- I'm on a SUN Cluster passive/active 2-servers system
- server1 accesses database D while server2 is not used (the oracle instance and EM console run on this server)
- if server1 dies, then server2 starts Oracle instance for database D and become the active node
- The EM repository was created in server1 (and SYSMAN was created in the database)
- the repository does not exist in server2 (the files mentioned above)
- I can't create the repository when I'm on server2 because SYSMAN already exists in the database
- Therefore, when the cluster switch from server1 to server2, I just copy these files so that "emctl start dbconsole" work on server2...
- I do exactly the same when I switch back to server1
- I can't create an OMS server, we're not using RAC nor DataGuard....

All you need is the copy of the folder with your machinename_sid over the next folder. The files in the $ORACLE_HOME/sysman/config are the generic files. You need the files and folder that contains the information of the configured EM on server 1. So copy that to server 2 and issue , emctl start/stop/status dbconsole.
That said, you mentioned that Symans already exists over the server 2,this means that there is already some repository available.What is it for ?

We need how to copy macro logic in the system

Hi Experts,
we need how to copy macro logic in the system, we have some macros in my friend system, i need how to copy macro logic , can u send me elaborate.
Regards,
BABU

I'm a bit uncomfortable with you've wanted to do especially you and your friend has a different system (unless its a sister company/industry). If this would be the case you can copy your friend's macro with the help of your basis team to transport them in one system to another.
if the case is different organization, I'm not sure if that is possible since no industry have same requirements but i may suggest the links below for your reference on how to copy the Macro into external system. Hope the document is relevant to your issue.

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.

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 !!!

Do I really need to Shadow Copy Backup Drive?

I am running SBS 2011 Standard. Every once in a while I get "volsnap event id 25 (The shadow copies of volume \\?\Volume{4bac8e93-04ed-11e2-814f-90b11c020377} were deleted because the shadow copy storage could not grow
in time. Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied.)".
The referenced volume is actually my backup drive which is a "simple, basic, NTFS primary partition" without an assigned drive letter which is entirely devoted to Windows backup destination drive.
VSSADMIN LIST SHADOWSTORAGE shows:
Shadow Copy Storage association
   For volume: (\\?\Volume{4bac8e93-04ed-11e2-814f-90b11c020377}\)\\?\Volume{4ba
c8e93-04ed-11e2-814f-90b11c020377}\
   Shadow Copy Storage volume: (\\?\Volume{4bac8e93-04ed-11e2-814f-90b11c020377}
\)\\?\Volume{4bac8e93-04ed-11e2-814f-90b11c020377}\
   Used Shadow Copy Storage space: 2.094 MB (0%)
   Allocated Shadow Copy Storage space: 2.93 GB (1%)
   Maximum Shadow Copy Storage space: UNBOUNDED (100%)
which I assume means VSS is actually keeping a shadow copy of the backup drive (or trying to).
My question is - do I really need to shadow copy this volume? If not would I stop this by the following command?
VSSADMIN DELETE SHADOWSTORAGE /FOR={4bac8e93-04ed-11e2-814f-90b11c020377}

Just did a quick bit of research on this and I think the error may be misleading.
If you go into Disk Management, right click Disk Management, All Tasks - Configure Shadow Copies
Do they show as Disabled on that volumeID?
If I go into Windows Server Backup and check out the Details, I see (on this system) 70.63gb of Backup Items, and 186gb of Copies. Which tallies up with what I see under List ShadowStorage.
So, what I suspect is happening (although happy to be proved wrong) is that the error above is VSC making space on your backup disk, or some other management process of the backups themselves.
I expect if you delete that Shadow Storage you will in fact, be deleting the backups.

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

While doing Homogeneous Copy after database restore below error coming, advise me here to come out the issue...
User table belonging to the dbo schema were found in the database DEV
you can only install an SAP system in a database(MCOD), or you instale a JAVA add in, you might have to convert the existing sytem to its own schema, or contact your SAP support.....
Thanks in advance.

Why do I need a bootable copy of my hard drive?

A little while ago I got a little too enthusiastic about reclaiming space on the drive and mistakenly deleted my Receipts folder. So far the eMac is fine, but I've been advised I should perform an archive and reinstall of the system, and, just in case, to make a bootable backup of my hard drive first, and to buy an external hard drive that could make such a copy.
My question is why I need a bootable copy of the hard drive. I'm a light user (internet, Quicken, no video games, movies or graphics processing), and after deleting duplicate mp3 files, unused printer drivers, stripping unneeded languages from programs, and cleaning out those un-deleted files left after deleting programs, I'm down to 13G used on my 40G hard drive (and the old beast just whizzes around). I can save that much stuff on my (new) 16G USB drive, which won't be bootable. So, why should I worry about bootability?

You know, I think you're right. I'm marking this solved because you just validated my thought. My to-do list is long enough without hovering over a hard drive for a couple of evenings and hoping and praying I do things right.
The Apple store is open today, but I think I'll wait until tomorrow and toddle over to our local Mac reseller (buy local-ish!) and pick up something that's plug-n-play. And, even though I've only got a 40G drive, and about 20G to back up, I'll probably end up buying something bigger (and partition a small volume for my backup) so that when I finally do buy a new computer I'll already have a backup drive.
