Mesure/Calculate IOPs in the production server?

We have production SQL Server and need to measure average IOPs so I can say to possible SAN vendors what is
the minimmum IOPs for my server.
- What is the calculation/measurement procedure: Can I use PerfMon and if I can what are the specific counters and how to use it to make the calculation
- Can I use any other tool for mesurement
- Or there are many other factors that are affecting on the server performance.
Simple: SAN vendor asks us what RAID we want and what number of IOPs we need for our SQL Server.

Josh,
it's becomes even more convoluted than that. For example, IBM sans can have SVC's (San Volume Controllers) that have SSDs and RAM local for caching. That's in addition to the SAN Ram that also does caching... Add the automatic tiered storage with it, or
like with an XIV where it constantly shifts everything around and you really don't have too much control over things.
In terms of Brent's post, he's correct but makes it sound like it's not worth anything. You can calculate the average latency and IOPS size form the DMVs, perfmon also has those counters which would be more accurate. In terms of SLQ Server we're going to
have things like 8k, 64k, 128k sizes. Since most IOPS are given in terms of 4k sizes this, overall, does little to help us. Couple that with the items from perfmon and we get a slightly clearer picture. In the end, though, we ultimately have no control over
this so using IOPS as a best guess is ideal over someone saying "Well, gee, I dunno... enough so it runs fast"

Hi Swapna,
Please check the logon group properties for SAP system in t-code SMLG. If there is any issue with logon group then it might cause for this issue.

How to mirror between the production server and the multiple local servers.

I am currently looking for the best way to correspond between our production server and the multiple local servers. Because the production server is the only server that holds the latest updating applications, and our local servers are located for each developer’s local machines where the all modifications and creations are done. So when the developer locally makes changes for assets or files, he creates a patch archive first, then accesses to the production side Administration console screen and imports them from Application Management screen.
We tried to find a way to see the imported date before (so we know which one has been imported as new.), but there is no show in the Administration console Application Management screen. There is Creation date but it’s set as we initially imported the full archive files, but not patch files. Since between applications have some types of the dependencies (like fragments or image files), what is the best way to keep mirroring between the production server and local servers? Or we should simply not use patch file for updating server?
Thanks,

Locale shown in the wrong language in the production server.

I have an application with a few projects which all have two locales - faroese and english. When I run the application on the default application server on my local machine it works fine with faroese locale but when I deploy to our production server and try to run it from there the faroese locale doesn´t work anymore for one of the projects.
For this project the values which are bound to properties files in my viewcontroller are shown in faroese as they should when the application is run from the production server but those values that are bound to the entity objects and view objects properties files do not work as they should anymore. The english values are shown instead of the faroese so the english property files are reached but the server doesnt seem to be able to figure out that the faroese properties files exist or it for some reason prefers the english locale for this project while it can figure out to show the other projects in faroese So I guess the error is somewhere in my Model project since the faroese locale works for my other projects on the production server but I can´t find out where.
So now I hope someone here has experienced something like and can tell me what I need to do to correct this.

Hi,
I think you hit a problem with upper/lower case names of the resource bundle files (*.properties).
Even windows file system is not case sensitive your file names MUST be exact as resource bundle manager is searching.
This works on embedded AS because the resource bundle files are located directly on the file system.
When you deploy the EAR/WAR file to the external AS then the files are located by the jar/zip finder which is case sensitive!
e.g.: bundlefile_EN.properies is not the same as bundlefile_en.properies
Hope this helps.

How do you test any SAP objects before a transport to the production server

How do you test any SAP objects before a transport to the production server?

Hi Rama Krishna,
The actual process is develop the object in development system and unit test there with the available data.
Then move it to Quality server where the data will be the actual replica of production and where the integration testing and ened to end testing happens and also the user acceptance testing happens there.
and once everything is found fine there then it is moved to production system.
Award points if this is helpful.

FTP folder location is not showing in the production server but exist in the development server.

Hi,
a wired glitch in my SSIS 2005 package in production server where the FTP folder location is not showing but its existing in my laptop version
EX: - t01/app/_res folder
When i open the package from the production server "_res" is not showing within the remote path in the file transfer task.
but "_res" folder is shown in my development environment.
I tried with winscp FTP software in the production sever , and was able to access the "_res" location through the FTP software. What could this be? a BIDS sofitware version issue???
VS 2005 Version in development server
-Is 8.0.50727.42(Premier Partner ENU) .net framework is 4.5.1
VS 2005 Version in production server
-Is 8.0.50728 (Premier Partner ENU) .net framework is 2.0 Service pack 2.0
thanks.

When you open the package on the production server, do you mean opening it with your Windows account from BIDS on that server? Ff the ftp connection in the package has a password it will have been stored in your laptop when you designed the package. when
you deployed the pacakge on the server as a file and open it with BIDS then the password will be gone. You would have to go into the package ftp connection properties, reassign your password and save the connection and the package again.

Charm Impact on changing the production server

Hi All,
we currently using Charm for a three system ECC landscape.
Now currently so many changes are there in various stages.
now , the team is planning to change the production server to high availabitlity server.
there will not be any change in the transport route and all, only instead of existing server, the new server details will be added.
I just wanted to know will there be any major impact in the current chagnes.
kindly advice.
Thanks,
Subhashini.

Hi
its like system migration to the new server? or it is by client export?
can you refer the thread [How to replicate Existing running Production server.|How to replicate Existing running Production server.]
and read the note [Note 1395727 - ChaRM project does not work after product version changed|https://websmp130.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=1395727]

Synchronizing Disaster Recovery site with the production server

Hi All,
One of the customer is asking the following query:
"How Disaster recovery site can be synchronized with the production server and how do they switch? Will the web logic server do this for them?"
This customer is having two sites one live and one a DR (Disaster Recovery) site on different location.
Can somebody answer my query?
Thanks in advance.,
Regards.,

Firstly
Is your Datagaurd Physical( Redo Apply) or Logical( SQL apply)?
Does it have Datagaurd Broker?
When Datagaurd is setup in your environment - on the primary database( live database) the Datagaurd users LGWR or/and ARCH process to collect redo data and ship this data to standby ( DR site) and the FAL process to provide client-server mechanism for shipping archived logs to standby.
On standby database, The Datagaurd users RFS process to receive redo records from primary database, the MRP process applies redo information to standby database.
If the Data Gaurd Broker is enabled, Datagaurd also used DMON process to manage and monitor both primary and standby databases as a unified configuration.
When there is any connectivity issue to the standby and when connection is re-established, the accumulated archive logs are automatically shipped and apploed to stanby, until stanby is resynchronized with the primary. This process does not require any administrative intervention.
If there is a very large Archive Gap between the primary and secondary due to some major issue. Then the unshipped archive logs need to be shipped manually from primary to standby and needs to be applied in standby to sync up with primary. For some reason there will also arise rare issues like problem with not applying of archive logs though log shipping is success. So some work arround will solve it.
Comming to planned /unplanned outages of production site.
Datagaurd has Failover and Switchover( planned ) methods, These are not automatic, but have to be explicitly initiated by the administrator( So there will be downtime but minimal). Once initiated, Datagaurd automates the processes involved.

How to deploy selected components on the production server with the same solution

Hello,
We've a production server where we had deployed the visual studio based solution which contains all the web parts and their business logic. Production server is up and running live and end-users have started using it as well.
Now, some issues and change requests have been reported regarding some components (web parts). We've made all the relevant changes. However, I want to deploy only those selected components (web parts) instead of entire solution again.
So, as per my understanding, if i include the selected components in the package/feature then at the time of deployment, wsp retracts the old solution and deploys the new one. When the new one won't have those web parts which didn't updated then portal/site
will start giving error and site will be collapsed.
Another option is to create another farm solution in Visual Studio 2010 and add the updated components in it. Then, we may be able to deploy it. Then, i'll be able to remove the old web parts from the selected pages and deploy the updated one.
Is there any better option which anyone could let me know?
Thanks!

Hi Sohaib, your another option is a good idea, only make sure to retract and remove the original from your farm, the add and install the new updated solution. And if you run into any error that says features already exist, you can use powershell, install-SPSolution
and -force to get the new solution deployed. http://tinyurl.com/q8erz72
Or, you could use Upgrade-SPSolution with a package that has same features from original, with the new artifacts. Although, if any of the original features are modified, I would recommend retract remove redeploy.

Hi,
but sir by setting /3gb paramter , kernel memory will be reduced by 1 GBYou only need 10-20% of total RAM for the kernel!
It's 4GT! How much RAM is on this server?
A VERY COMMON issue with Oracle 32-bit Windows is that the server has 8 gig RAM, but the SGA only uses 2 gig, leaving huge wasted RAM areas.
See these important notes for sizing your SGA and PGA:
http://www.dba-oracle.com/art_dbazine_ram.htm
Also note that you do not have to use $GT, you can also use AWE instead:
http://www.dba-oracle.com/oracle_tips_ram_waste.htm
does it mean windows 32 bit platform is unfit for oracle?All 32-bit systems are constrained by addressable memory (2**32~=2 gig).
To use larger RAM regions, you must employ special tricks In Windows, 4GT or AWE) to move the data buffers "above the line".
Hope this helps . . .

Actual site URL in the production server?

We have published one site from management to production. How do we access the actual site from production? What will be the URL to access the site?
Thanks
Arijit
N.B. We can access the page from management server using the below url:
http://<ManagementHost>:<ManagementPort>/cs/Satellite?c=Page&childpagename=<SiteName>%2FABPageTemplate&cid=<pageId>&pagename=FSIIWrapper

Hi Arijit,
Production URl's can also be accessed just like you access management url. like-
http://<prod host>:<prod port>/cs/Satellite?c=Page&childpagename=<SiteName>%2FABPageTemplate&cid=<pageId>&pagename=FSIIWrapper. This can be used for testing purpose only, accessing production in this way is not recommended.
There are many options to manage URL's in production like implementing Friendly URL's, using webserver redirection etc.. your site name must be configured in the webserver.
Also CatalogManager and TreeManager servlets should be disabled in the production.
Thanks,
Harish

How can I set up Mavericks Server on a Test Mac without affecting the production server

I have Mountain Lion server running as on an xserve as our main server, it has developed a few issues particularly related to Profile Manager and Certificates.
So I was going to use the move to Mavericks as an opportunity to have a fresh start.
So I want to set up Mavericks Server on a mac mini temporarily to test it and configure all the services before moving it to the Xserve as the main server.
My question is what is the best way to do this, obviously I can't use the same IP or hostname as the main server if it is connected to the network, and some services can't be set up without a network connection.
So do I give it a new IP and hostnmame for now and then change it later on, my concern is that changing the hostname might cause issues down the line.
So what is the best way to set up a fresh server in preperation as a drop in replacement of the current server?

Ok I got the test server set up fine and cloned it over to a spare partition on the Xserve.
But when I booted into the new partition several things broke.
1st the IP address changed itself despite the fact it is set to Manual, The Alert section of Server.app let me repair this.
Profile Manager no longer worked, the web page just said Profile manager could not be found, was working fine on the test mac
Tried deleting the OD master and resetting Profile Manager but it still didn't work.
DNS needed repairing and restarting
I decided at that point to abandon it and go back to the test mac where everything is still working.
Any tips for overcoming these issues.
I have thought maybe it would be best to turn off all server services before making the clone and then turn them on one at a time once it has been restored to the new partition on the xserve
Also if the certificates that are created when making an OD master were made on the mac mini does that cause a problem when it has been restored to a different machine, should I leave OD off and just set it up when it is in its final place?

How to use tools to monitor databae if the production server is not direct

accessed? We access our prod server through jump server.
On my workstation, I have plsql developer intalled, and wonder how I can use my tool to connect to the prod server?
Is it posible?

No, I support internal client. I used to support external client in other company, as long as I log into vpn, and oracle client tnsnames included those sid, I should be able to log in.
The jump server is not citrix, it is another unix server with ssh ability. I guess it is firewall issue.
How to get around with it? change firewall rule

It seems I have to do all command line scripts from now on.yes & enjoy!

How to find the date when object is moved from quality to production server

Hi Experts,
I am working with BADI ZMM_PUR_REQ_PROC_001-Method Check and BADI ZME_PROCESS_PO_CUST-Method Check.
I need to add a check that a particular logic should be implemented only after this object is moved to the production server.
How can i check the date when an object (in my case this BADI) is moved to the production server?
<Removed by moderator>
Thanks in advance.

Hi Sakshi,
So your reqt is that the documents created after your Transport implementation date should pass the check and others (old ones) should ignore.
I will recommend, if at all possible, to make all the old documents compatible to your check by doing a separate initial loading /one time activity to avoid this kind of hardcoding.
IF not at all possible to do so, then I think you should better hardcode your Transport req number and fetch date (AS4DATE) from E070 table and only if any entry exists, use that date as your required date. I believe this will be the date of transport imported in the target system.
You can avoid hardcoding Transport number by picking latest transport with respect to your object (BADI) using E071 table, but that will go wrong once you send any future changes in this BADI to Prod, so better to hardcode the transport.
