Some experience multiple farms same database server?

Hello
There is some experience using the same SQl database server with multiple farms?
Thanks

Hi JLSF,
There should be no problem, the only thing you have to keep in mind is database names.
For instance: Person 1 creates a content database: WSS_Content in farm 1.
Another person creates a new Web Application in farm 2 and tries to name the Content Database WSS_Content as well. In this case, you will probably run into problems.
So as long as you make sure ALL databases created (Service Applications, Content Databases, Config database, 3rd party applications) you should be fine.

Incorrect/Corrupt Farm Configuration database server name

I have a SharePoint 2007 farm (version 12.0.0.6219) with a corrupt configuration database (SQL Server 2008 R2) consisting of a Central Administration server and a database server for Windows SharePoint Services Database. In a failed attempt to move the configuration
database to a new SQL server, the farm is referring to a SQL server that no longer exists. All databases on the new SQL server have been successfully moved from the old SQL server, but SharePoint does not recognize the configuration database. The network name
of the old SQL server has been aliased to the never SQL server, so the farm is operational. But the
Servers in Farm page states the old server as the configuration database server.
After doing my own research, it appears to me the issue is in the Objects table in the
SharePoint_Config database below.

It looks like all I’d have to do delete row id’s ...E1F704E35A94 and ...45408E818ED5 (<red>red</red> row #’s 8 and 2) after shutting down all SharePoint Web Applications and services. Then update
Old SQL Server with New SQL Server. Possibly even deleting row ...B0EF78226512 (orange row # 3) could be done as it appears to be an orphaned part of the configuration. These ids are not referenced in any other table in this database.
Any help on this would be appreciated. Thanks in advance.
P.S. Sorry it looks like my table rendering didn't work as intended.

are you using the SQL alias to pointing to the Config Database server?
did you stop all the timers services, admin services other services before moving the Config DB and configuring the alias to new server.if you did not then it will corrupted.
If you are not using the SQL Alias and using the sql server name then you cannot move it.
you need to rebuild new farm with creation of new Config DB, then create SSP /Web apps and attached your content Database.
Directly playing with the Config Database is not a good idea at all and i am sure deletion is not supported in any means.
Please remember to mark your question as answered &Vote helpful,if this solves/helps your problem. ****************************************************************************************** Thanks -WS MCITP(SharePoint 2010, 2013) Blog: http://wscheema.com/blog

Sharing virtualized database server between two Sharepoint farms (intranet and extranet)

We have a Sharepoint 2010 intranet farm and are currently getting ready to upgrade the Sharepoint 2007 extranet farm to 2010. Can these two farms share the same database server (same SQL Server 2008 instance)? SQL Server is running on a virtual
machine with 24GB of RAM. From my research it looks like theoretically they can but in practice do I need to consider other factors such as processing power and other burdens on the db server? The web server for intranet is on the company's internal
network. The web server for the extranet will be in the DMZ.
Content database sizes:
- intranet: 60GB
- extranet: 30GB
Total estimated number of users (total for both): around 500 users.

Why does the upgrade relates to both farms being supported on the same SQL Server instance ?
Do you mean you plan to take the 2007's content database and attach it to the 2010 Farm ? To use
stsadm -o addcontentdb command ? In the end of the process, you'll have a single 2010 Farm ?
If so, then, yes. As long as SQL Server 2008 must be 64bit with SP1, and disk latency cannot be sluggish.
But if the plan is to migrate all farm databases, and have all SharePoint databases coexisting on the same SQL instance, then you will have to work your way if both farms use the default database names SharePoint_Config, WSS_Content, WSS_Logging.

OLTP and OLAP databases on same SQL Server?

Would you put OLTP and OLAP databases on same SQL Server or separate?
I realize the ideal would be separate, but that means 2 expensive licenses instead of 1. Most of our OLTP stuff happens during the day while OLTP processing happens at night (so good use of resources) if just 1 server. Also, the disks that hold
the files could have different allocations (small chunks for the OLTP disks, large for the OLAP disks). Also, by being on the same database server, the OLTP data is immediately accessible for processing into the warehouse.
Or, is it just a cardinal rule to never mix the two worlds as server completely different purposes?
Thanks.

Answer given in simillar below thread would help you for sure:

Is keeping your OLAP and OLTP databases on the same server is considered bad practice?

Shared database server

When architecting the EP 6.0 many months back I came across some documentation stating we should use a separate Database server for our portal environment. Now I am looking for this documentation again but I can not find it. Has anyone heard of such a requirement from SAP? Our management would like to put the EP database on a shared DB server. Does anyone have any experience with heterogeneous databases on the same database server?

Hi Shaun,
Might be irrelevant to you, but neverthless a word of caution from my side.
We were planning to use shared SQL servers for our portal installation. The shared environment was used by many non-SAP applications too. We ran into problems when we found out that the server collation of the shared system was not the one required for EP6 installation i.e. CPI BIN 850 char.
If you are planning to use a shared SQL server and if the server collation is not the one mentioned in the installation guide, of which there is a fair chance if there are non-SAP applications running, then you will definitely run into problems.
Correct collation of the database you create in the shared system is necessary but not sufficient. The EP6 installation checks the collation of database server as well.
Regards,
Aniket
PS: Would be happy if anyone can give a workaround for this problem.

Two different WCS instances, pointing to the same database

Hi,
for some unknown reason that came from the architecture fellows, I need to install 02 instances of WCS pointing to the same database server. I mean, both instances would need to "share" the database. They don't want a cluster schema because they need to have the option to deploy the app in one instance and, if wverything is ok, deploy to the remaining instance.
Do you know if such architecture is possible? I did the installation of one instance(instance A), but when trying to install the instance B referring to A's database, I get a ton of errors.
Any advice is much appreciated.
Regards,
Vinicius

Hi,
This is not the way Sites has been designed. Each instance should have their own schema and repository unless the two instances work as a Sites cluster.
So what you're trying to achieve is not possible using your approach. What I could suggest is to install two separate instances on its own, create the necessary data model, asset configurations, templates, etc. in one instance and replicate it to the other instance by publishing it to the other instance using real-time publish. If you use LDAP or any other supported directory server you would be able to use a singe directory for both sites instances.

External or Internal IP for Database server machine?

We have a web server machine with firewall controlling our network security. This server gets some critical data from a database server machine located also in the same local network. Which IP is secure for database server, Internal or External IP ?
regards
Siyavuş

Internal IP
For security reasons, is better if you could use a DMZ, with the web server in the DMZ, and the database server in the internal network
Something like this:
Internet <-->external firewall <--> DMZ (web server, mail server, etc) <--> internal firewall <--> LAN (database, pcs, etc)
If you want more granularity, you could incluse put the internal servers in another DMZ

Cannot open 2 Virtual Machines at the same time to access the same Database

Folks,
Hello.
I am installing Oracle Database 11gR2 RAC system using 2 Virtual Machines (rac1 and rac2) on the top of VMPlayer 3.
The VM rac1 and rac2 run correctly when one of them is shutdown.
Their locations are F:\VM_RAC\rac1 and F:\VM_RAC\rac2.
While rac2 is running, I open rac1. But this error message comes up:
Error: "Cannot open the disk F:\VM_RAC\sharerac\asm1.vmdk or one of snapshot disks it depends on. Reason: failed to lock the file."
While rac1 is running, I open rac2. But this error message comes up:
Error: "Cannot open the disk F:\VM_RAC\sharerac\asm1.vmdk or one of snapshot disks it depends on. Reason: failed to lock the file."
The 2 error messages are the same. This means I cannot open 2 VMs rac1 and rac2 at the same time. When we run RAC system, we have to open 2 machines or more than 2 machines at the same time so that all machines can access the same Database Server.
My question is:
Can any folk tell me how to have rac1 and rac2 run at the same time ?
Thanks.

You need to disable disk locking, which ordinarily is performed by the first VM to prevent any other VMs from corrupting your vmdk files via uncoordinated writes. You will have to shutdown both of your VMs and edit the *.vmx flat file for each, adding lines like the following (settings taken from workstation 6, but should be nearly identical settings for VM Player 3.x):
http://crosbysite.blogspot.com/2007/10/clustering-in-vmware-workstation-6.html
scsi1.sharedbus = "Virtual"
disk.locking = "false"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
A few comments:
- your shared disks (scsi1) must be on a separate virtual scsi bus than the boot disk (scsi0), to allow setting the sharedbus flag as seen above.
- you must also ensure the cache parameters and unsynced writes settings are set to guarantee that all IO is immediately flushed to the vmdk file so the other VM can immediately access the latest version of data.

Orcale App Server and Database Server in a distributed setup

Hi,
I had a question about orcale db server. Now, as I understand it in a cluster there is one database SERVER and each machine in the cluster has access to the shared database server.
The entire cluster presents a unified view of the database server. To the developer it appears as though there is only one database server.
Is it possible to have several such clusters and run a query across these clusters in a transparent manner? Say I have Table 1 on database SERVER 1 and table 2 on database SERVER 2. Given the current architecture SERVER 1 is on CLUSTER 1 and SERVER 2 is on CLUSTER 2. Can I run a query joining Table 1 and Table 2 such that I do not have to worry about where CLUSTER 1 is and where CLUSTER 2 is? I am nit talking about partiitioning where one table is spread across nodes in a CLUSTER but is still within the same database server.

Sandeep

Multiple copies of same database on a 2 node RAC server - How to merge ?

I currently have multiple copies of the same database running on a 2 node Rac system. I am looking for a way to combine them into 1 large database but keeping the data separate.
The databases are copies of production for testing, development and a yearly "historical" databases .
All the databases are created from production, and generally have the same schema's , tables, procedures, etc however may be different versions and need to be.
Is There a way to use one large database and logically split all the different versions of the same objects into their own space in one database ? The structure cannot change as the database is for a 3rd party's Forms application the relies on the objects not changing names etc.
Ideally I am looking for a solution that will allow the forms application to connect to "test" and "historical" copies of our production database separately in the same database container.
Thanks for any direction.

Oracle dblink to sql server, accessing multiple database on same sql server under one dblink

Hi, we have successfully managed to set up an Oracle dblink over to sql server and retrieve data.
The sql server user were using via the dblink has access to more than one database on the same sql server
But the question is how in oracle (if at all possible) do you prefix the sql statement to access this ?
Eg:
Sqlserver_prod has user sqlserver_user which appears to be set up as default database on sqlserver_db1
But we have select access to sqlserver_db2
all work fine as sqlserver_user
select * from table_fromdb1
select * from dbo.table_fromdb1
select * from sqlserver_db1.dbo.table_fromdb1
as does
select * from sqlserver_db2.dbo.table_fromdb2
over in Oracle
Oracle_db has dblink sqlserver_prod.world connecting as sqlserver_user
all working fine
select * from "table_fromdb1"@sqlserver_prod
select * from "dbo"."table_fromdb1"@sqlserver_prod
but how (if at all possible) do I access from oracle
sqlserver_db2.dbo.table_fromdb2
without having to create a new sqlserver_db2_user referenced in a new dblink
if oracle to oracle would be
select * from remote_oracle_schema.table@remote_oracle_db

Hi, ok cheers, I see, original gateway was connecting purely at host_name level
HS_FDS_CONNECT_INFO=sqlserver_host
Planning to amend this to be
HS_FDS_CONNECT_INFO=sqlserver_host//sqlserver_db1
With exisiting dblink
And to create new gateway
HS_FDS_CONNECT_INFO=sqlserver_host//sqlserver_db2
With new exisitng dblink,will see how we get on
Cheers again

Is it possible to copy the same database multiple times simultaneously?

This is the setup of my environment.
I have a 'master' database that contains the full schema plus some pre-populated data such as default settings. When database schema changes are made, they get made to the master database. When a new customer signs up for the service, I make a copy of this
master database (using SMO) that will now be the database containing all of the customer's information. The database is rather large, and the copy operation can take a couple minutes.
Everything works fine as expected, unless I try to provision two new customers at the same time. It appears that Azure only allows for one DB copy operation at a time. Is there a way to allow for copying the same database multiple times simultaneously?
Thanks for you input. I understand that this is likely not the optimal setup, and that there is many better ways of doing this, but I am somewhat heavily invested in the current process and I would like to find out how to make it work if I can.

BTW, you can do this programatically by using PowerShell (https://msdn.microsoft.com/en-us/library/ee210569.aspx), SqlPackage (http://www.benday.com/2012/12/18/deploy-a-sql-server-database-projects-dacpac-with-sqlpackage-exe/)
or the SQL Server binaries for .NET (http://www.vijayt.com/Post/Deploying-a-data-tier-application-in-SQL-Azure-programatically)
Hope this helps.

Multiple installations of XI 3.0 on the same Windows server

Hi,
is it possible to have multiple instances of XI 3.0 installed on the same Windows server? I know that I can create seperate database users for the repositories and that I can have different ports configured for CMS. I'm concerned about the registry and whether a second installation would overwrite the registry for the first installation or if there are anyother show stoppers.
Thanks,
Matt

Not yet, I know our product group is looking at this but currently only 1 per windows server. They are now supporting XI3 on top of XIR2 or other products known as side by side install. I don't have any type of ETA and wouldn't expect it soon.

Tim

Multiple web-app sharing the same database.

hi experts,
If I have several websites running on the same server. Most of the are sub-domains of the same domain, they share the same database, but each sub-domain will have their own web-apps(This also means that they are running on a different java virtual machine, right? ). My question is that how can I make them communicate with each other. Also, will there be any conflict with the database insert/update issues, and How do I solve that?
For example, if one user is already logon from "tips.mydomain.com", then when the users goes to another sub-domain, say "java.mydomain.com", he/she doesn't need to re-login again.
thanks.

Well yes, having databases accessed by multiple users simultaneously is an issue that many many developers have had to face. But the answer to "How do I solve that" doesn't fit in this little box or in the limited time that people have available to answer questions here. It's an extremely complex issue about which entire books have been written.
As to the bit about the subdomains, it is possible to map them to the same web server, as far as I know, but that's a web configuration issue and nothing to do with Java programming.

Some experience multiple farms same database server?
