• grid vs dbconsole for multiple databases on the same box

  Hello

  I need to start the control of several instances that are on the same server.

  Ideally I would be able to cover the case of 4-5.

  How dbconsole compare to the Grid Control in this case? I think the problems of memory - is it possible to have 4-5 dbconsole processes running on the same box?

  I hope that the answer is dbconsole and grid no, because we have put in place on grid.

  Thank you for your valuable answers.

  Dbconsole is the stand-alone version of grid. Of course it has limited the feature console grid.

  If you have enough memory you can start the console as much as you want.

  Consumption of memory can vary accordingly with the number of controls that you want to perform. (with the agents of the grid or dbconsole).

  Once again, the answer is depends.

• Multiple databases on the same Instance SQL vcenter

  I know that this is possible, my question is for the cumulative jobs created specfic (I think during the schema updates).

  I asked our DBA to create a vCenter Lab DB and a Lab DB update on our SQL2008 Server Manager using the scripts described in the ESX and vCenter Server Installation Guide (I'll use new unique Lab DB names and Lab DB SQL users). This SQL server instance already has a production DB, and DB Manager production update vCenter.

  My question is what is happening with the schema updates when I leave the installation of the laboratory to the schema updates.

  1. I should do something before installing vCenter to avoid potential conflicts on the side DB?
     
  2. Will be the schema updates are trying to recreate the jobs of rollup and fail, breaking existing jobs, or something else?
     

  
  I'm looking for good practices so that when I install the lab, the environment of existing production DB (including rollup jobs) are not affected and cumulative Lab new jobs are created to function properly.

  I'm not a DBA, so if I'm far away feel free to correct me.

  The installation creates the names.

• Multiple vCenter on the same server database

  Hi all

  I'm migrating vCenter vCenter 5.5 5.1.

  Is it possible to use the same server SQL2008R2 for vCenter 5.5 database?

  Installation vCenter 5.5 database to the same server vCenter 5.1 will be will damage the 5.1 database? Use different database?

  What is the best way to secure the vcenter 5.1 during the installation of vcenter 5.5 database other than the database backup 5.1?

  Also does need seprate SSO database?

  Thank you...

  I used SQL dissferent account and vCenter was insalled on the new database without problems.

• Start up problem when having multiple databases on the machine

  Start up problem when having multiple databases on the machine:
  
  I installed two databases.
  
  When I stop the database and try to start using
  
  Startup pfile ='... location... " ;
  
  I get ora-12514: TNS: listener is not currently know of service rquirest in connect descriptor
  
  When I try again after 3 seconds, I get a new error, ora-01041: internal error. Hostdef extension doesn't exist
  
  Stop and start gave no problems when I had a database. Why I get problems when I have two databases?
  
  I use: show the pfile parameter. SPFile; to make sure that I have the right parameter locations, the error should not be the location.
  
  I never installed two databases on a single machine, then perhaps that I make mistake of a first - timer.
  
  Anyone know how to get this working, i.e. start and stop DB without problems?
  
  The oracle 11 GR 2 on Windows 7 64 bit, everything works normally.

  First of all... the Oracle Service for the instance must be started for the DB that you try to connect or start.
  Next... from the command prompt:

  Set oracle_sid =

  sqlplus sys as sysdba

  Startup pfile = 'location of the pfile respective db.

  Now, if you want to start or connect to another DB, which is on the same server (again assuming that the Service is STARTED)...
  From the same command prompt or other session...

  Set oracle_sid =

  sqlplus sys as sysdba

  Startup pfile = 'location of the pfile respective db.

• Installations of multiple Apex on the same server

  Hello
  
  We plan to spend some of the data in our Oracle database to another database on the same server.
  Now the problem is that there are a number of Apex applications that use these data.
  So I wonder if it is possible to create a second installation of Apex (and HTTP server?) on the same server, connect to the new database.
  
  We use the database with Oracle HTTP server and Apex 3.1.2 10.2.0.4.
  
  
  Thank you
  Matthias

  Hello

  a database can have only one installation of APEX active. But you can have several databases with an APEX in each database
  on the same server. You can even use the same HTTP server - you just neen an additional inscription of DADDY for the second database APEX
  in your dads.conf file, for example

  
  :
  Database configuration data 1
  :
  

  
  :
  Attributes for the second database here

  Does that help?

• Firefox does not work for multiple instances of the SAME user account on Windows Multipoint Server 2011

  We have a PC HP of MulitSeat MS6200
  It runs Microsoft Windows MultiPoint Server 2011 (which seems to be a twisted version of Windows 7)
  It is implemented in a laboratory of computer science and students connect you using their account for shared room - IE multiple instances of the same user accounts are currently running on the PC at the same time.
  The first student to run Firefox can work with it without a problem.
  However, when another student try to start firefox they get the following message:
  Firefox is already running but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

  Cannot start Firefox using a profile that is already used by someone else.
  Each Firefox instance needs its own profile or you will get this error message.

• on the headphones for different databases in the same ORACLE_HOME

  Hello experts, I have a doubt
  
  I installed 3 different databases on the same server that OS is Suse Enterprise 10. Right now, I'm just a listener who registers all the services. The number of connections is great for two of the three databases, so I don't know what could be the best practices for this environment. I have a question I would like you suggestion for me:
  
  DB version: 11.1.0.7
  
  Should I have three listener, one for each database?
  
  Is advisable to have a single listener for multiple instances on the same server?
  
  Are there different between have only a single listener for the instance and have a port for listening, for example?
  
  What about performance?
  
  
  You in advance, I hope that you can guide me.

  Best practices is not not to have multiple databases on a server, based on resources.

  Should I have three listener, one for each database?
  N ° it is quite undesirable and requires more administration.

  Is advisable to have a single listener for multiple instances on the same server?
  Yes. Don't forget the listener is only a broker and there is no permanent connection between the client, listener and database.

  Are there different between have only a single listener for the instance and have a port for listening, for example?

  Yes. The latter is a nightmare of administration.

  What about performance?

  Who cares? The only factors are
  Listener.log becomes too large--> put in place the appropriate cleaning procedures
  The semaphore count is exceeded (Unix) or no more threads can be created (Microsoft Windows95), who will give birth to ora-12500.

• Multiple copies of the same mail and "unresponsive".

  I have fought with Thunderbird for about a week now and have had no chance to solve my problems. Any help would be greatly appreciated! I tried all the suggestions on the FAQ page.

  Here are my symptoms:
  -Make multiple copies of the same email with the same time stamp.
  -Not pulling new e-mail messages.
  -Whenever I try to navigate upwards or downwards in the Inbox or open an email TB will does not.
  -J' got warnings from the following script:
  Script: resource://gre/modules/XPCOMUtils.jsm:323
  Script: chrome://messenger/content/mailWindow.js:179

  Here is what I tried:
  -J' completely removed and reinstalled TB (and recovered my profile).
  -J' have compressed files.
  -J' rebuilt the database world.
  -From TB in safe mode does not seem to make a big difference.

  Fortunately, I have access to webmail via my ISP and it works fine.

  Thank you!

• Constraints/General to keep PROD and databases on the same Machine TEST

  Hello
  
  Version: 12.1.1
  Database is 11.1.0.7
  2 node architecture (DB on a single Machine, applications on the same Machine)
  
  Client wants to keep PROD and databases on the same Machine TEST. Could you please let me know the issues and constraints that we can encounter this configuration in the future. While I can force the client to a machine more TEST.
  
  Thanks in advance...

  Hello

  My Client told me that I can provide more resources (CPU, memory, and disk), then why can't keep us as what he asks?

  There are other technical problems, that we can meet?

  I think the above should be enough :)

  Other proceedings continued would be impossible (as you said, because of human error, and in case the server restart is required). Even if they provide more resources it would be a conflict over shared resources (for example, what happens if a process on the test instance consuming all CPU/memory resources?).

  So, in futuere, we can improve the database to the new version and some environment variables in the registry may have affected it?

  Each instance will have its own entries in the registry and this shouldn't be a problem.

  Thank you

• Download the image to the directory and database of the same form data

  Hi all
  
  I play to build a shopping cart (never done before) a tutorial of Gordon Knapp at www.webthang.com.
  
  I created the site and it works perfectly. Now, I want to extend it.
  
  There is a form that allows the user to add data to the database. I would also like to be able to transfer an image to a directory on the server and add the data to the database at the same time of the same shape. It would be good if the input field "< input name ="product_picture"type ="text"id ="product_picture"tabindex ="6"size ="50"/ >" could be filled automatically by the file name of the image being downloaded, but it's not a neccessity.
  
  I looked at different packages ASP Upload and I can upload a single image, but none of them clearly show how to download the image and add data to the database at the same time.
  
  It is a private project I need suggestions for free.
  
  The tutorial shows how to create Dev Ultra site but works perfectly well in DW. The page looks like this. It is named "admin_add.asp":

• Multiple sites using the same instance of CF?

  Hi Gang-
  I have a client who has recently improved CF Pro to Enterprise and they use in a relatively simple way as an intranet. They would like to help me configure a second instance for the purpose of a staging server, but I noticed after they revealed they do not have the link of Enterprise Manager in their CF Admin screen.
  
  They need to reinstall CF using the MultiServer installation version to be able to deploy a second instance of CF? Need to uninstall and reinstall? Ugh...
  
  Can't they just create a second site under their web server, using a different port and you worry about the second instance of CF? Best practices for a moment, remember, they do not necessarily expand on this server, it is intended to be a staging server.
  
  Any ideas on the best and fastest way to handle this?
  
  Many thanks in advance,
  Rich

  Many questions, many answers. :-)

  Yes, rich, they would need to install the version multiserver for you to see this Enterprise Manager option in the CF Admin. But no, they would not need to uninstall the server deployment (what you did) to add to the MultiServer deployment. They can coexist (although it is not something most would do in general).

  The best news for you is that, Yes, they can indeed just set up a second site on their web server, and who also point to the deployment server CF one you have installed. It is, of course, assuming that they are running a web server that supports multiple sites. If it's Apache, you're good. If this is Windows, then as long as the Windows Server 2003 (or 2008 or Vista), you're good, too. (Just to be complete, for other readers, XP does not allow you run multiple sites at the same time.)

  If during the installation of the CF tells you that there all sites on the web server with CF, you need do nothing again create site. It should be immediately able to run pages CF. If you said that it is in CF link to a site, then you will need run the server web Configurator again. You can do it manually, even after installation. See the CF Admin and Config docs to learn more about it, as well as on this issue. (I know many like to just run things and hope that the interface is pretty clear, but as this issue shows, for some things anyone installing CF will be well served by looking at this collection of Miss often.)

  Hope that helps, Rich. It is not a RTFM response. :-) Suffice it to say that if you need more that what I said, it's in the manual. Yet, I am happy to answer follow up if I can.
