Multiple dbcontrols

Platform: Oracle 10.2.0.4 EE
OS: windows XP-Pro
Of course I know that dbcontrol is used to manage one and only one database. But on my laptop (my 'sandbox' database) I'd like to have a couple of databases and not have the additional overhead of Grid Control. It seems that multiple dbcontrols should be possible as long as port conflicts were avoided. In poking around MetaLink on this, I found note 353857.1, "How To Configure More Than 19 Db Control Consoles Per Machine?", which seems to confirm my hypothosis.
After duplicating my CREATE DATABASE scripts and modifying for a different SID, the scripts ran without a hitch. I have two instances, two dbconsole services. A look at portlist.ini shows entries for both consoles and both agents, and no conflicts between ports. However, I'm not having any luck with the second console. So far, it has been a variety of errors, sometimes I can reach a console, but it reports everything is down, other times I can't even get the web page, and I've not been able to get consistent sequence of errors. I'm continuing to work with that and dig through the logs, but I thought I'd go ahead and toss this into the hopper. It seems like some had posted on this subject just a few weeks ago and referenced a document on how to do this, but I can't seem to find it now.

Ed,
You might try using the Oracle Database Upgrade Assistant against the database with the non-functional DB Control. If that does not work, try the Oracle Database Configuration Assistant. If you are still having problems, try recreating the repository.
It is possible to have more than one functional Database Control on a server running Windows.

Didn't find anything in dbua or dbca, but running emca to drop and recreate the dbcontrol and repository seems to have fixed the problem. I'm not sure exactly what was going on there. I did go back and look at the emca log from the initial db creation scripts, and see that it reported some errors with network adapters and passwords.
Thanks for the pointers.

Multiple dbcontrol (EM) not sending alerts

I have two database instances on the same machine.
two listeners: port 1521 and port 1522..
two dbcontrol services (EM) port 5500 and port 5501..
one of them sends out the EM Alert emails, the other does not.
but I can send a test email from it so I know it is configured properly.
any ideas?

Very, very few installations can justify the additional configuration/maintenance/complexity of multiple listeners on a single machine.

OEM Access

Hello,
I have 4 instances up on a remote server. I am only able to reach the EM manager link for 1 of them through my local machine using Internet Explorer, which happens to be the first one that I created. I have checked all instances to make sure that emctl is up and running. I can connect to the initial instance that i set up just fine but for the other three I just get the "Internet Explorer cannot display webpage error. If I actually ssh into the database server(RHEL 5) and bring up the GNOME desktop and use mozilla, I can get to all 4. Any thoughts as to why I can't access the other three from my local machine?

Each OEM would be configured to run on its own port. Thus ..
1) are you specifiying the correct port for the OEM console you want to contact? (go to the server, set ORACLE_SID appropriately, and start the control with 'emctl status dbconsole', and notice the complete url, including port, that is reported)
2) Since you can connect to all four from the host machine, this pretty clearly suggests a firewall issue. Do you have an entry for each in your iptables?

How to run two OEM?

Hi All,
I have two instances on one server, "orcl" and "clone"
"orcl" was the default one so Oracle Enterprise Manager is displaying for that instance.
How can I get another OEM for "clone" instance?
Thanks

How can I get another OEM for "clone" instance?To monitor and manage multiple DBs, you need to license & install GRID ControlTechnically, that is not true. While dbcontrol is designed to manage a single instance, there is nothing to prevent creation of multiple dbcontrols on a single box. I actually have two 10.2.0.4 EE instances on my laptop right now, each with its on dbcontrol. Each control runs on its own port and thus requries a separate url:port combination to reach the oem console.
A few months ago I even had my hands on a ML note describing how to increase the number of ports available for multiple dbcontrols from a default of 19. Poking around ML just now and I can't seem to dredge it back up.

Creation of multiple database

how to creation and monitoring multiple databases in one linux box

hi
thanks for the reply.
but i am not able to monitor multiple database,but one sid at a time.
i need to monitor multiple database at a time using OEM or through SQL
please help me out and let me know the procedureIdeally you would install and use Grid Control.
But you can also have multiple databases on one host, each with it's own configuration of dbcontrol. You have to make sure ORACLE_SID is properly set when you run emca to create the dbcontrol and when you run emctl to start the dbconsole. Each instance of dbconsole will run on a different port that you have to include in the url when you try to acess it through your browser. The correct url (with port) is reported at dbcontrol creation, and at dbconsole startup.

Roll Back a Transaction from a DBControl

Hello BEA Experts
I have a DB control ,and there is a method in it that inserts data into a table , this method gets called multiple times and if a call to this method fails I would like to roll back the changes made by priors calls to that particular method with in a transaction.
My problem is that if I use a DBControl will I be able to manage the transaction and roll back if something gooes wrong as I wasnt able to find any example of such a scenario.I would appreciate if anyone could point me in the right direction and an example would be great, or should I use a custom control rather than using a DB control and I am using oracle9i and theres only one Database and I am not using EJBs

Administrators can reassign tasks, but they currently can't (in 11.1.1.4) move process token(s) backward/forward to a different activity (including human tasks). That capability, known as "grab", is planned for an upcoming release.

Em dbcontrol finally working

I installed oracle 11gr2 on 32 bit windows 2003 (datacenter) Microsoft Windows [Version 5.2.3790]
with 8 g memory (using PAE) and really had trouble with dbcontrol. It did not get installed correctly
the first time and I took me days to get it working eventually. (The problem being how to permanently modify parameters in the database without it? It would be great if there were just a command line way
to do that.) so anyway I am posting a way that worked for me
to get it working. Which might not be the best way or the only way. In retrospect I think one of the
issues here is regarding creating the loopback adapter per instructions:

next set of instructions more or less. 2.4.2 Installing Oracle Database on Computers with Multiple IP Addresses

the place of it. perhaps IP number can be substituted for "domain name" ? If you don't have a static
ip then you don't have a static domain name either, if you did have a dns service in the loop.

How do multiple family members use iTunes.? One account or multiple?

How do multiple family members use iTunes. One account right now but apps gets added to all devices and iTunes messages go to all devices. Can multiple accounts be setup and still have ability to share purchased items?

Hey Ajtt!
I have an article for you that can help inform you about using Apple IDs in a variety of ways:
Using your Apple ID for Apple services
http://support.apple.com/kb/ht4895
Using one Apple ID for iCloud and a different Apple ID for Store Purchases
You can use different Apple IDs for iCloud and Store purchases and still get all of the benefits of iCloud. Just follow these steps:
iPhone, iPad, or iPod touch:
When you first set up your device with iOS 5 or later, enter the Apple ID you want to use with iCloud. If you skipped the setup assistant, sign in to Settings > iCloud and enter the Apple ID you’d like to use with iCloud.
In Settings > iTunes and App Stores, sign in with the Apple ID you want to use for Store purchases (including iTunes in the Cloud and iTunes Match). You may need to sign out first to change the Apple ID.
Mac:
Enter the Apple ID you want to use for iCloud in Apple () menu > System Preferences > iCloud.
Enter the Apple ID you want to use for Store purchases (including iTunes in the Cloud and iTunes Match) in Store > Sign In. In iTunes 11, you can also click iTunes Store > Quick Links: Account.
PC (Windows 8):
Enter the Apple ID you want to use for iCloud in the Control Panel. To access the iCloud Control Panel, move the pointer to the upper-right corner of the screen to show the Charms bar, click the Search charm, and then click the iCloud Control Panel on the left.
Enter the Apple ID you want to use for Store purchases (including iTunes in the Cloud and iTunes Match) in iTunes. In iTunes 10, select Store > Sign In. In iTunes 11, click iTunes Store > Quick Links: Account.
PC (Windows 7 and Vista):
Enter the Apple ID you want to use for iCloud in Control Panel > Network and Internet > iCloud.
Enter the Apple ID you want to use for Store purchases (including iTunes in the Cloud and iTunes Match) in iTunes 10 in Store > Sign In. In iTunes 11, click iTunes Store > Quick Links: Account.
Note: Once a device or computer is associated with your Apple ID for your iTunes Store account, you cannot associate that device or computer with another Apple ID for 90 days. Learn more about associating a device or computer to your Apple ID.
Thanks for using the Apple Support Communities!
Cheers,
Braden

How can I setup a mail-specific passcode/restriction on iPad used by multiple family members?

How can I setup a mail-specific passcode/restriction on iPad used by multiple family members?
Have an Exchange mail account setup and accessible in my mail on iPad... however my kids use it and i would like to restrict them from accessing this specific portion of the device. I tried viewing restriction options and do not see that i can apply a restriction specifically to Mail. Thanks for your help.

Not a feature of iOS. Check the AppStore to see if there are other
mail apps that allow passcode protection.
Or use Safari to log onto your email via a web-based interface and
enter your credentials each time. A bit slower, but the kids will
not know the details to login.

How can a family with multiple existing accounts use Home Sharing?

I'd like to use the new Home Sharing feature, but it appears to be restricted to families in which all of the family members share a single user account.
We already have separate accounts for each family member. Is there some way for us to use Home Sharing without abandoning most of our existing accounts, along with all of the purchases made by those accounts? I don't think anyone in this situation would be willing to do that.

Eh. I am not too sure since I have not messed with it much but I do have a great deal of experience with multiple accounts. Each computer can be authorized for multiple accounts. As can iPods. iPods can sync songs/videos/apps from multiple accounts as long as the computer is authorized with them. What I have set up here, is I buy my stuff I want, my parents buy what they want and so do my brothers. When my bro gets something I want I just move it to my computer. That way all our accounts are separate, but if there is something I want I can get it. Also, since the music no longer has DRM, it won't matter. It will play on any computer. What you should see is if you can just do the shared library with multiple accounts. Then if you don't have videos or such, you can get apps or music. Hope this helps!

How can multiple users use the same Creative Cloud Individual on one single-machine?

We have one shared graphics workstation, which is infrequently in use by different people - therefore we bought a single-workstation license (which we were referred to "Creative Cloud Individual"). In the FAQs it says it installs locally, but whenever a user different from the installing adminstrator logs in, he is forced to use the trial.
Is there a way to make the local installation usable on that single machine for multiple users?
Thanks in advance for your reply

Serenatasystems do the other users not have administrator access? What happens if they sign in using the Adobe ID tied to your Creative Cloud subscription? Do your Adobe Creative applications then exit trial mode?

How can I use multiple ipad's on one account without sharing individuals personal email accounts?

Is it possible to have multiple ipads on one account and share info, but also allow the individual users to have personal email that is not seen on the other ipad's? We have all ipads on same icloud account because we all need to see the same ical. It seems like that's the problem. If it IS related to icloud then if we have separate icloud accounts, how would we share the main ical otherwise? Sharing the ical is very important for this business so everyone can access the daily schedule. Of course each user still wants to have private email.
Hope this wasn't too confusing!
Thanks!
Doreen

you could set up the main icloud itunes acount for ical and not have in setup on the devices
and share the calandar with the other itunes accounts on the devices
or only have it on one device
devices have the users indervidual itunes icloud setup
they should be able to access the shared "main" itunes icloud ical account once it's shared
http://howto.cnet.com/8301-11310_39-57542557-285/three-methods-for-sharing-an-ic loud-calendar/
if the devices are company owned you could go futher and setup find my iphone on the main itunes account
and not on the user icloud accounts

What happens on iCloud (ex. contacts) when multiple family members use the same Apple ID?

What happens on iCloud when multiple family members use the same Apple ID? For example if we all choose to use iCloud for contacts, are they all merged together? We use the same Apple ID so we can use find my iPhone to keep track of the whole family.

Of course if you are both connected to the same iCloud account you have the same contacts - what did you expect?. The contacts live on the server and are read from there by the devices; so as you've both managed to sync your contacts up to iCloud they are now inextricably mixed. You can only delete your contacts by deleting individual ones, and doing that will delete them from your phone as well.
You can only unravel this by
1. In the iCloud contacts page at http://icloud.com, select all the contacts, click on the cogwheel icon at bottom left and choose 'Export vCard'.
2. Sign out of System Preferences>iCloud
3. Create a new Apple ID and open a new iCloud account with it for your own use.
4. Import the vCard back into the iCloud contacts page.
5. Go to http://icloud.com and sign in with the original ID. This is now his ID. Work through the contacts individually deleting the ones you don't want him to have. When done sign out and advise him to change his password.
6. Go to the new iCloud account and delete his contacts individually.
Of course if you have also been syncing calendars and using the same email address there are problems with doing this.

ICloud with multiple family members sharing one iTunes account?

How will iCloud work for the case where multiple family members share an iTunes account but each has his/her own iPhone/iPad/PC?
Will iCloud replicate content based on email address, unique Apple ID, iTunes account, or?? If iTunes, we could have trouble as three of us share our iTunes account (started when our daughter was young and continued for simplicity).

Keep one Apple ID for iTunes purchases (apps, music, etc.) for all family members on the iTunes Store and use different Apple IDs for each iCloud user. That worked for me.
