Need for administration server in a cluster

Hello everybody,
          I'm working on a project where we intend on having a weblogic cluster with an undetermined number of nodes. When deploying to the production environement, all weblogic domain configuration is handled using templates and homemade scripts. The weblogic instances are running on different servers and each of them has all the domain configuration installed, including applications to deploy. Now on the initial startup of the system, it seems that none of the cluster nodes will start up the first time without the administration server running, even though the msi-config.xml file exist for each node. I get an error indicating that it cannot perform authentification using boot.properties (non encrypted username/password at this point). If I start the admin server, then all nodes can start and will then subsequently start without the admin server running. Is there no way to configure a weblogic cluster so it is able to start up the first time without the admin server running?
          In this project, monitoring of the each weblogic server instance is performed by an in house product. The need for the administration server at the first startup complicates things for us. I should mention that the domain configuration works fine when not running in a cluster.
          We are using Weblogic 8.1.4.
          Best regards,
          Anders

The API is not public.
          This non rmi object that is living in JNDI, sounds like out of band data.
          If this object doesn't contain any state you can bind it from all the
          servers but don't replicate the bindings.
          Hope this helps.

Permissions needed for sql server job to execute stored procedure on linked server?

Hi all
I have a job step which attempts to call a stored procedure on a linked server.
This step is failing with a permission denied error. How can I debug or resolve this?
The job owner is sysadmin on both servers so should have execute permission to the database/proc I'm calling, right?
The error is:
The EXECUTE permission was denied on the object 'myProc', database 'myDatabase', schema 'dbo'. [SQLSTATE 42000] (Error 229). The step failed.
My code is:
EXEC [LinkedServer].myDatabase.dbo.myProc
Also tried:
SELECT * FROM OPENQUERY([LinkedServer], 'SET FMTONLY OFF EXEC myDatabase.dbo.myProc')
With the same result.
Any help appreciated.

The job owner may be sysadmin on the remote server. The service account for SQL Server Agent may not. And it is the latter that counts, since the it the service accounts that logs in and impersonates the job owner. But the impersonation inside SQL Server
does not count much in Windows, and it is through Windows connection is made to the other site.
One way to resolve this is to set up a login mapping for the job owner. The login mapping must be for an SQL login on the remote server.
You can verify the theory, but running this query from the job:
SELECT * FROM OPENQUERY([LinkedServer], 'SELECT SYSTEM_USER')
By the way, putting SET FMTONLY OFF in OPENQUERY is a terrible idea. This has the effect that the procedure is executed twice. (Unless both servers are SQL 2012 or higher in which case FMTONLY has no effect at all.)

Selecting VHDx as storage for File Server Role (Failover Cluster 2012 R2)

Is it possible to select an already existing (offline) VHD or VHDX as storage when creating the "File Server" role? Reason I want to do that is because I already have a file server setup as a virtual machine and causing issues so my company
decided to make the change towards a File Server role.
Thank you
David

Hi David,
Do you mean you configured it to file server failover cluster via "High Availability Wizard" ?
I think you need to choose a shared volume between two nodes to achieve high availability .
Please refer to following link :
http://technet.microsoft.com/en-us/library/cc731844(v=WS.10).aspx
If you do not select a shared volume , I think there is no difference than sharing a mounted VHDX file on a standalone file server .
I would suggest to copy these files to CSV and share them .
Hope it helps

10.1.0.2.0 database download link needed for window server 2008 64bit

Here is our plan. We are currently running oracle 10.1.0.2 database on a windowsServer 2003 32 bit.
Now we would like to migrate the database to 10gR2 and run it on our new server windows server 2008 64bit. After doing research, I think I need to go through the following step:
1) install 10.1.0.2 on our new server,
2) clone the database using the current back up data on the new server.
3) install 10gR2 on the new server.
4) using dbua to upgrade the older database to the new version.
Please let me know whether those steps are correct.
If yes, where can I download 10.1.0.2 version database for 64bit window server 2008?
The only link I can find is http://www.oracle.com/technology/software/products/database/index.html
but 10gR1 not listed.
Thank you very much!

Welcome to the forums !
10gR1 is de-supported, hence you will not find any download links. You will have to create an SR to see if Support can mail you the install media.
How big is the database ? One other option you have is to export the 10.1.0.2 database and import into 10gR2 on the new server. This will achieve the upgrade in one step and will not require the intermediate 10.1.0.2 version on the new server.

Need for NPS server certificate with PEAP-MS-CHAPv2

Hi,
I have a question about a small setup I'm currently testing. In a Wireless access with 802.1X authentication based on PEAP/MS-CHAPv2, and a NPS server (MS server 2012R2), I've noted reading technet documentation that the NPS server or other RADIUS server
do have a certificate (issued by a 3rd party CA or by an AD CS environment).
However, it remains for me a point I would like to clarify (sorry I surely have a bad understanding of documentation). If my client is configured for not "validate server certificate", do I still need to have a certificate on the NPS server ?
Well, I know it is not secured, but this will permit me to test without configuring an AD CS, and without buying a certificate.
Many thanks in advance for your answer.
Regards,
Fabrice

You also need a server certificate in this case as the protection in Protected EAP is due to the encryption of the TLS session.
Not validating the server certificate just means that no additional check of the name is done, so the client would be able to connect to any RADIUS server - given that its certificate chain is valid. But the certificate chain as such is checked as in every
SSL handshake.
You don't need a certificate issued by a commercial CA though - you could use an inhouse PKI. For tests you could use a self-signed certificate as well.
Edit: If you want to test self-signed certificates the easiest way is probably to install the web server role and use its built-in option to create a self-signed certificate.

Unreconciliable need for Administrative Privileges for Installation

My automated detection of updates for Flash Player alerted me tonight that an update is available but claims that it requires administrative privileges in order to proceed with the installation.
I was completely unable to locate, even with help from a Google search, the file responsible for these updates and so took the logical step of downloading the whole thing separately.
I gave the installation file administrative privileges but it still claims "process not elevated".
**This is a serious security issue that I need resolved.**
It is insane to use programs/code that are susceptible to malware attacks without the ability to stay updated with the latest security updates and if my issue cannot be resolved I will have to consider ceasing all Flash activity.

I have solved the problem and am posting what I discovered here so others experiencing this problem can benefit.
http://www.howtogeek.com/howto/windows-vista/enable-the-hidden-administrator-account-on-wi ndows-vista/?PageSpeed=noscript
"Many people familiar with prior versions of Windows are curious what happened to the built-in Administrator account that was always created by default. Does this account still exist, and how can you access it?
The account is created in Windows 7, 8, or Vista, but since it’s not enabled you can’t use it. If you are troubleshooting something that needs to run as administrator, you can enable it with a simple command.
Note: You really shouldn’t use this account for anything other than troubleshooting. In fact, you probably shouldn’t use it at all."

How can I avoid the need for Administrator rights for open registry key.vi

Dear wire workers.
I would like to do an EXCEL export.
Therefore I like to check if EXCEL is installed or not.
I use 'open registry key.vi' and read out the Excel\InstallRoot.
If there is an installed EXCEL than I export the data using ActiveX.
Everything works like a charm with LV 8.5.
The problem I have is that 'open registry key.vi' useses RegOpenKeyExA from the Advapi32.dll.
RegOpenKeyEx does, in fact, create a non-existing key and returns 0 (ERROR_SUCCESS?).
LONG lRegResult = RegOpenKeyEx(HKEY_CLASSES_ROOT, m_RegSubKey, 0, KEY_QUERY_VALUE + KEY_WRITE, &hkRegistry);
Successfully opens or creates m_RegSubKey under HKEY_CLASSES_ROOT.
Is there a way aroun this call?
In fact you need administrator rights to do this call because of the try to write a non exsisting key.
In my case this avoids the EXCEL export and any kind of registry access from LabVIEW without administrator rights.
:-) Who the hell has done this ;-)
All ideas are welcome
With kind regards

Hi Martin
Did you try to wire a "KEY_READ" constant to the security access mask input of the open registry key VI? I had a similar problem, if you just need to read a key or check if it's present use read access only, that should work.
Hope this helps,
Daniel

Information needed for Precalculation Server

Hi All,
I am installing Precalculation server for BI Broadcasting. Can i use only 1 Precalculation server for DEV, QA and PRD OR i should use 3 individual precalculation server for DEV, QA, PRD.
Thanks

Hi Simon,
As per my investigation I found, we should use only one server per BW system. If we want to use same precalculation server for multiple BW system, we should use Virtual Machine on precalculation server. Any comment?
Other thing is as you mentioned we should consider this server as any other server, but precalculatin server is nothing but few services that runs on Windows. So do we have to treat this server same as any other SAP system?
Thanks

Domain Users To be Given IPads thats will File Sync to a Windows Server in the Company DMZ. Are CALS needed for the ipads ?

Hi Guys.
We are thinking on giving some Sales Staff some IPADs to use. All these staff currently have USER CALS.
We are going to be using some software called MobileEcho to allow for browsing and File Syncing from a Windows Server in a DMZ. This Server itself maybe doing some LDAP queries to the LAN. Also some users maybe putting new content onto this Server
from the LAN. Are any seperate Device CALS needed for this Server ?
thanks

if the user is assigned a User CAL, no device CAL is needed.
That's the main reason why you would buy User CALs, where there is more than 1 device for each user (or more devices than users, in general)

Download for SQL Server machine running Windows Server 2008 Enterprise SP2

I am confused what 11g product to download and how to configure for the above server. I just need for SQL Server 2008 to be able to communicate with some Oracle databases. I don't need to manage the Oracle database, nor do I need to create one. I just need to be able to create linked servers, use SQL Plus, and create some SSIS or DTS packages that will bring Oracle data into the SQL Server. I think I just need the client, but for 11g, I see it is less than 1GB in size. I am afraid I may be missing something because I thought the client downloads were about 2GB, but the 2GB downloads are not called "client". This is a 64bit machine running an Intel Xeon X7460 chip.
Our server has a C:\, D:\, and E:\ drive on it. The data (.mdf) is on drive E:\. The normal environment is on C:\ like usual. I also need to know if I need to set environment variables which I read about, but am not sure how to set them and make them stay, or if the software does that.
As an aside, I tried installing a 10g on there that the DBA downloaded and could never get it to work, although I was successful in getting tnsping to work, but SQLPlusW would close on me when I tried to connect and SQLPlus failed with some error but can't remember what right now. I uninstalled it. I think it may have been the wrong download.
I would appreciate any info at all, even if you don't know about everything said here.
I have a link here where I think I am close, but I still am not sure. Let me know if this is correct and which link to click. If I am wrong, please provide the correct link if you can. Thank you.

Hi,
To integrate Oracle with SQL server you need the following
Install Oracle 11g Release 2 client software
Install Oracle 11g Release 2 ODAC software
Restart SQL services
Configure OraOLEDB.Oracle provider
Create linked server
Add remote logins for linked server

Getting ipaddress or host name for virtual server

I want to get the ipaddress or host name for virtual server in a cluster environment. If i do
java.net.InetAddress.getLocalHost().getHostName()
it returns the ipaddress of the physical node currently running virtual server.
Is there any way to get the ipaddress or host name for virtual server ?

You can get the hostname by clicking on the account properties in outlook, but the port you connect to must be opened by your system admin.

Getting host name or ipaddress for viirtual server

I want to get the ipaddress or host name for virtual server in a cluster environment. If i do
java.net.InetAddress.getLocalHost().getHostName()
it returns the ipaddress of the physical node currently running virtual server.
Is there any way to get the ipaddress or host name for virtual server ?

Might help to define what you actually mean by "virtual server" and what you actually want as well (and from what process.)
For example a clustered system with a single entry point. And you want the client to have the entry point. In this case the virtual address (ip and/or host) should always be returned. You can't get the individual address of a specific server. If that is not the case then something is wrong with the clustered system, not java/client.
Another example, a server in the cluster. Then it only knows about its own real address. If you want the cluster then you have to explicitly deliver that information to it, the box itself does not know it.
Something else?

Administrative Server - Single Point of Failure?

From my understanding, all managed servers in a cluster get their
          configuration by contacting the administrative server in the cluster.
          So i assume in the following scenario, the administrative server
          could be a single point of failure.
          Scenrario:
          1. The machine, on which the administrative server was running got a
          hardware defect.
          2. due to some bad coding one of the managed servers on another machine
          crashed.
          3. a small script tries to restart the previously failed server from step 2.
          i assume, that step 3. is not possible, because there is no backup
          administrative server
          in the whole cluster. so the script will fail, wen trying to start the
          crashed managed server
          again.
          did i understand this right? do you have some suggestions, how to avoid this
          situation?
          what does BEA recommend to their enterprise customers?
          best regards
          Thomas


Hi Thomas,
          There is no reason why you couldnt keep a backup administration server
          that is NOT running available. So that if the primary administration server
          went down, you could launch a secondary server with the same administration
          information and the managed server could retrieve the required information
          from the backup administration server.
          regards,
          -Rob

Do we need to format data and log files with 64k cluster size for sql server 2012?

Do we need to format data and log files with 64k cluster size for sql server 2012?
Does this best practice still applies to sql server 2012 & 2014?

Yes. The extent size of SQL Server data files, and the max log block size have not changed with the new versions, so the guidance should remain the same.
