Database Copy LUN Size

Hi,
Quick question about database copies and the storage requirements.
I understand that for a DB copy, each MBX server has to have the same drive letters for the relevant drives/LUNS, but what
about size?
Do the drives have to be the same size?
The reason for asking is that we already have two MBX servers and all our DBs have copies on drives that are exactly the same
size. We are looking to replace the underlying hardware one by one (i.e. introduce a new MBX server to the DAG and copies, then eject the old one, rinse and repeat), and are hoping to increase the capacity of the drives at the same time.
Thanks.

Hi,
Agreed. DAG members should have the same drive letters, same LUN sizes.
Best regards,
Belinda

Database Copy size

Dear
We make Exchange Designs for more than a decade now. We always use the storage calculator as a second opinion tool. The Exchange 2013 storage calculator always calculates the database copy size 1.5 times the active Database. However, comparing both, the active
and the copy on a production DAG, both do have the same size? I think this 1.5 factor is not necessary, even not OK. Because that means that you should make your Active database storage a large as the calculated database copy storage size. You need to be able
to switch from active/copy to copy/active.
So, why is the database copy size 1.5 times the active database when using the storage calculator?
Regards.

Not sure I follow. There are a lot of components and factors in the Exchange 2013 storage calc. For example, if you are talking DB copies, Content Indexing, and Transaction Logs of a passive copy on the same disk & has a truncation
fault tolerance & designated LAG, then I would expect disk requirements to be different than a totally different configuration. Feel free to share your calc example.
Be sure that you are using the latest version of the calc; it does update and there are fixes.

Database copy in iseries servers

Hi,
I have a query.
On I Series AS/400 system, we need to refresh production system (P04) to exsting quality system (Q04).
database size of P04 is around 250 GB. Remote CLient copy is not feasible as it will take days to complete.
In case of database copy, save P04data library to tape in production system. Then restore P04data from tape to Quality system. Replace existing Q04data library with P04data library. is it possible?
If not then what is the procedure to delete existing Q04 system in order to perform Homogenous copy.

Hi Sailesh,
There is another forum called "SAP on DB2/UDB on i5/OS" - i5/OS is the new name of AS/400 and iSeries.
CL program to refresh SAP instance
have a CL program to refresh WAS ABAP.
Good luck,
Victor

Database Copy to another

I have a SQL database on Server1 called DB1. I need that entire database copied over to a different
server (call it Server2) each night. I'd like to schedule a SQL Agent job to do this.
I'd prefer not to setup a linked server on Server2 so that's why I'm asking this question.
What is the best practices method of accomplishing this? Is the best route to schedule a native backup of DB1 on Server1 and then schedule a restore of that .bak onto Server2? I worry about the job failing if people are connected to DB1 on Server2 at the time
of the scheduled restore.

Method 1:
Sept 1 : Backup database from source to local drive, ( What is the database size ), if size is small then you can directly place the backup the file to destination server, and if the backup size is large then you have to backup to local then you have
to copy to destination...
Sept 2 : copy the backup file to destination and restore that data base with NORECOVERY
Robocopy syntax :

Method 2 :
If this is just for a DR then you can do the below..
You can configure database mirroring or Log shipping to implement the same.
If there is any other purpose , for example generating any nightly reports or anything then you have to restore the database with RECOVERY and etc...

Database copy procedure

Hello All,
How can I copy my PRODUCTION server data to DEVELOPMENT server.
Prd Server System Information.
Database: Maxdb 7.5
Operating system: Win 2k3 SP2
Database size : 57GB
Development server has same configuration of PRD server
should i directly restore PRD offline backup to Dev server. Will it work?
Please guide me...
Best regards
Amol

Hi Amol,
Ideally I shall not recommend you to make database copy from PRD to DEV since all the version management in the development system will be lost by doing this.
For your question:
Development server has same configuration of PRD server
should i directly restore PRD offline backup to Dev server. Will it work?
Yes. It will work.
Alternate solution
As you are interested in copying PRD data to development, I would suggest you to create a new client in Development system and perform client copy from PRD to Development (new client) with SAP_ALL profile.

Deepak Kori

Database copy Move data

Hello,
I have a database A. of about 15GB size and want to copy the data across to database B. - same schema just a few additional tables.
When I use Oracle Sql developer and click on tools- database copy and select my source A and destination B. truncate objects the process starts
but..does not copy any data at all. - it takes only 3 minutes as well.
why is that?

well I dont just want to create a duplicate of database A. because B. contains some tables that are still important but unique to B.
most of the tables between A. and B. are the same and I just want to copy them over from A to B.
Using the Oracle SQL Developer seems to get the similarities between the schemas and copy those table over BUT it somehow forgets the data altough there
is a DATA MOVE as part of the copying procedure.
I know there is the options to create migration repositories but this all seems to complicated to me.

Lun Size best practice for UC apps and VMWare?

Hi,
We have UCS manager v2.1 with FI 6248 direct FC attached to NetApp with plenty of storage.
Per following doc, Lun size for UC apps should be 500GB - 1.5TB and 4 to 8 VMs per Lun.
http://docwiki.cisco.com/wiki/UC_Virtualization_Storage_System_Design_Requirements#Best_Practices_for_Storage_Array_LUNs_for_Unified_Communications_Applications
We have four B200M3 blades and 3 to 4 UC apps (CUCM, Unity, UCCX) will be hosted on each blade. May add more VM the blades in the future.
I am thinking four 1 TB Luns and one for each blades. (actually 8 Luns in toal, 4 boot luns for ESXi and 4 for UC apps).
What is the best practice (or common deployment) to create Lun size and design?
Thanks,
Harry

UC apps need low IO，nothing special，Reference vmware LUN design is ok.

How to set local file copy buffer size?

Is there any sysctl parameter or any other mechanism to set or change file copy buffer sizes? I'm backing up a huge number of files to a local hard drive connected by firewire, and I'd like to play with file copy buffer sizes for the best performance. The machine used is a new macbook pro running OS-X 10.6.7. Any ideas?

Here is a bash script that uses the dd command to copy a file. Use the -b option to set the file size.
example:
/Users/mac/config/forumcopy.command -vb 4096 /Applications\ $Mac\ OS\ 9$/Civilization\ II/Civ\ II\ Map\ Editor /Applications\ $Mac\ OS\ 9$/Civilization\ II/Civ\ II\ Map\ Editorv8
I haven't tested this a lot.
Of course, I haven't figured out how best to post code. Trying HTML mode. Using the <pre> tag.
#!/bin/bash
# macteracopy [ -b blocksize ] [-v ] [-V ] input_file output_file
# Purpose of this script:
# Copy a file with optional block size. Default size of 4096.
# Notes:
# chmod u+x macteracopy
# You may have to restart the finder to notice a customized file icon.

Javascript error in BEx after system database copy

Hello,
we made a database copy of our BW 3.1 system on another hardware. After having done everything described in the How-To-Guide "Enable SAP BW Web functionality", we called the BEx via URL. The login screen displays and also the Report menu, but there occur JavaScript errors on the page, that didn't occur in the copy master. E.g.
"SAPBWSSgdo is null or not an object" or
"SAPBWItemCatalog undefined".
These errors prevent the choice menu for BW report value options to be displayed, which is quite annoying. Does anybody know where the error might come from? Are there any components required by BEx which weren't copied with the database copy?
Thanks for your help in advance,
Volker Hofmann

Hi Beat,
thanks you're helping me! The MIME-Repository objects like JS-Files, stylesheets and images can be read. The strange thing is:
The J2EE engine is hosted by a provider. When they're calling the BEx web reports, they're displayed correctly. But when we call them (via proxy!), the error occurs. Even the application management doesn't know where the error comes from, after having checked if the proxy caches old data. The error is still not resolved...
Do you have another idea?
Regards,
Volker

Mailbox Database Copy Status Failed

We have 2 Exchange 2010 servers. We run a DAG. Recently I have noticed that database copy DB2 which is located on Exch-1 is showing "Failed". Database copy DB1 which is located on Exch-2 is showing Healthy. I searched online
for information regarding the issue with the failed database copy. I found information that led me to run these commands.
Suspend-MailboxDatabaseCopy -Identity “Mailbox Database XXXXX\Server Name”
Update-MailboxDatabaseCopy -Identity “Mailbox Database XXXXX\Server Name” -DeleteExistingFiles
It went thru the seeding process and completed but the database copy still shows "Failed". Copy Q Length is 19. I have refreshed the console. What else do I need to do to correct this? I did recently shut down Exch-2 server
for maintenance. thanks

Hi,
It's glade to hear the good news. Thanks for your updating.

SQL Developer Database Copy truncates DATE columns

Hope someone can help me. I want to copy all object from one schema to another schema in my Database. I have used the "tools - Database Copy" utility and it copies all of the objects and data however when I query the DATE columns in the destination schema the time element has been truncated? Why has this happened?
tab_h contains a column h_date of type DATE
Query
SELECT TO_CHAR(H_DATE, 'MM-DD-YYYY HH24:MI:SS') from tab_h;
returns
02-07-2012 09:54:14
from the source table
yet returns
02-07-2012 00:00:00
from destination schema? This is the case for all DATE columns in the tables.
I noticed this was happening in 3.0.04.34 and I upgraded to 3.1.07.42 and it still happens.
Thank you

Maybe there's a problem getting the OS settings right; try to add this to \sqldeveloper\bin\sqldeveloper.conf:
AddVMOption -Duser.region=USIf that works, you can try others closer to you.
Hope that helps,

How to Create a database copy and specify the source database.

Hello,
In my dag environment I would like to create a new database copy and specify the source. My company has database copies in 2 locations. Instead of transferring the data from one location to the other, I would like to specify the source be the copy that is
in the same location.
Thank you,
~Mark

Hi,
We can create a mailbox database, then run EMC and EMS to create a database copy.
More details about Add a Mailbox Database Copy, for your reference:
https://technet.microsoft.com/en-us/library/dd298080(v=exchg.141).aspx
Note: please pay attention to Prerequisites section, for example:
1. The specified Mailbox server must not already host a copy of the specified mailbox database.
2. The server hosting the specified database and the server that will host the database copy must both be in the same database availability group (DAG). The DAG must also have quorum and be healthy.
