What makes the session database so scalable in the Enterprise Edition?
How does it avoid becoming a bottleneck?

If you are enterprise customer then Sun has a good program called ASCSP program whereby they answers your architectural questions. They also help to give an estimate of the hadb nodes etc as per your requirements and shall give you performance tips to scale it . This might mitigate your scalability issues.
Hope this helps !!!

Service cannot be started. Microsoft.VirtualManager.DB.CarmineSqlException: Unable to connect to the VMM database. Ensure that the SQL Server is running and configured correctly

Hi All,
I am setting up SCVMM 2012 R2 in a production environment. Whenever I restart the SCVMM virtual machine the VMM service doesn't start automatically, I have to manually start it. I checked the VMM logs and in the event viewer i find the below error,

I added the 'VMMSVC' account as db_owner and sysadmin and also NT_Authority\System with same permissions still the service doesn't start on the start up.
I googled a lot and I find the threads with the error containing "General failure" but not with the above. Can someone please help me to find out why this error is occuring.
Thanks,
Ravi

It's often only a problem of the service dependencies. SCVMM starts to fast, SQL server on the same machine in not initialized yet. Here are working service dependencies to ensure SQL server is initializes before SCVMM starts.
You can set the service dependencies directly in regedit (as always: be careful modifying the registry ...)
Here is the content of a reg file setting the dependency.

Get the session trace files and also the TKPROF reports for storedprocedure

Hi ,
I am trying to find out the bottlenecks on a storedprocedure, which does a insert into a table, where the target table has lot of indexes/constraints, so i want to see, which indexes/constraints is causing the problem. so in order to do I want to get the session trace files and also the TKPROF reports to see the bottlenecks for a oracle stored procedure,
Could you please give us the list of steps to get the tracefiles and tkprof reports.

I understand it would be too much to expect you to actually Read The Fine Manual
I am using bulk collect for all in my storedprocedure to insert the rows into a big table. In order to perform analysis on this bulk collect which tool will help me to identify the bottlenecks .
I want to compare background session properties for both runs (like inserting the data with indexes/constraints vs without indexes/constraints). please let me know..I am willing to bet you the problem/slowness is on the SELECT side & not the INSERT!

Hi Dear,
You need install the database version 10.2.0.4.0 in 10g or version equal to higher than 11.1.0.7.0 with the database character set AL32UTF8.

Can you replicate databases from SQL Server 2014 Enterprise Edition to SQL Server 2014 Standard edition?

Hello,
Can you replicate databases from SQL Server 2014 Enterprise Edition to SQL Server 2014 Standard edition?
Thanks.

Yes, you can replicate from Enterprise edition to Standard edition. The only caveat is Peer-to-Peer Replication requires all nodes to be Enterprise Edition.

4) Data Guard (Not active Data Guard)
Thank you

With the Enterprise Edition, yes they are all part of DataGuard which is licenced. However, the Standby Instance, itself, needs to be licenced.

What is the equivalent Database Connectivity VI of the SQL Toolkit 'Set SQL Parameter to Null' VI ?

I am using the database connectivity (ADO based) tool and I want to be able to insert a null values.
I have included a simple VI that demonstrates how this works with SQL toolkit .
Null values are very useful and occur frequently in dealing with data. I wish that LabVIEW handled them much better - (e.g. there is not datatype in LabVIEW corresponding to a Null value).

The VI was not attached but I'm going to answer with what I have here.
- Currently, the Database Toolset converts NULLs to the default value for LabVIEW data types (ie, False for Boolean, empty strings, zero for numbers, empty arrays, etc). In the user manual there is an example that shows database records containing NULL values being first converted to a string, empty strings (the NULLs) are then converted to NaNs instead of the usual zero value. This method requires you to know what data types each field contains and that they know what to look for and how to convert the data.
You can go to this following link to suggest that a null datatype be implemented:
https://sine.ni.com/apps/we/nicc.call_me?p_country=&p_lang_id=US&p_form_id=58
-Also you cannot leave par
ameters values empty because there is a big difference between executing an SQL statement and doing a Parameterized Query, especially when looking at the low-level ADO layer.When doing Parameterized Queries, you MUST specify all parameter values - leaving them empty results in ADO trapping errors rather than using a default value.

What is limit of database size in oracle 10g standard edition/edition one

Hai All,
What is the limit of database size in oracle 10g standard edition and standard edition one.. I see the white paper of oracle says that the limitation is 500 GB. This limitation is correct.? if correct then what happened after the limit..?
Please help?
Shiju

What white paper would that be? I can't see any limit in the Oracle Database 10g Editions comparisons.

Can I deploy the session bean to 9i in the JDeveloper3.2

dear ONT
My JDeveloper3.2 can't find the method to deploy the session bean to 9i.
sk

I'm not sure that's entirely correct.
Personally I run both EJBs and servlets/JSP in OC4J. OC4J has all the 'web' features of IAS, including full SSL support.
From a speed perspective, running the EJBs and web components in the same container will give you a huge benefit.
Also I'm not sure what you mean by "you can't deploy EJBs into OC4J yet" - I do it daily? ;)

Verify whether the session data is kept in the Coherence caches

I have successfully combined the MapViewer application with WebLogic and Oracle Coherence*Web.
How to verify whether the session data of MapViewer application is kept in the Coherence caches or not?
All out put show that both of MapViewer and WebLogic server as well as Coherence are running well.
All the following steps are right?
The procedure is as the following:
1. Create a WebLogic domain: Map_domain.
2. Start the WebLogic domain Map_domain by running startWebLogic.sh script.
3. Install Coherence.jar as a library on WebLogic.
4. Copy the coherence.jar in the WAR's WEB-INF/lib directory.
5. Create a reference to the shared library by modifying the weblogic.xml in web applications WEB-INF directory
and add the following contents:
<weblogic-web-app>
     <library-ref>
          <library-name>coherence-web-spi</library-name>
          <specification-version>1.0.0.0</specification-version>
          <implementation-version>1.0.0.0</implementation-version>
          <exact-match>false</exact-match>
     </library-ref>
<weblogic-web-app>6. Install Coherence-web-spi.war as a WebLogic library.
7. Install the MapViewer as a WebLogic application.
8. Start a Coherence cache server using the cmd file web-cache-server.cmd and then start MapViewer application.
The content of web-cache-server.cmd file:
@echo off
@rem This will start a cache server
setlocal
:config
@rem specify the Coherence installation directory

Do I need the /3gb switch on Windows Server 2003 Enterprise Edition

I have an Oracle 10g database running on a Windows Server 2003 Enterprise Edition with 16gb of RAM. Do I need to set the /3gb and or /PAE switch in the boot.ini file for Oracle to use this memory?

This metalink doc talking pretty extensively about the setting
Implementing Address Windowing Extensions (AWE) or VLM on Windows Platforms
Doc ID: Note:225349.1
As you might know 32bit system has limitation of 4G max addressable memory issue. In Windows that's 2G limit because Windows reserve 2G for system. With /3G switch you can let Application address 3G with 1G for OS, if your system has more than 4G you need to use /PAE to address memory beyond 4G.
Of course if you don't plan to allocate more than 2G to Oracle SGA then don't need the settings.

Firefox crashed and I am not given an option to restore the session probably because I deactived the history, what can I do?

After a crash I closed out of Firefox but have not been given an option to restore my session afterwards. Also in my chronicles no sites show up. I did deactivate the history at some point. Is there anyway to recover my previously open tabs?

I have been in there before and tried to change the restore settings but could not restore my session
