Grub2 multiple installs on same pc

Hi friends, can we have multiple installations of grub2 on the same pc on different partitions ( not the MBR ) ?
For example , I have three partitions:
1) /dev/sda4 (500 MB)
2) /dev/sda5 (500 MB)
3) /dev/sda6 (500 MB)
can i install grub2 on all the above partitions at same time ?
Many thanks.

If you install each distro's GRUB2 to the MBR, but each install will overwrite the previous. You can use configfile to boot the other partitions. In arch anyway, you can use grub-install to reinstall arch's GRUB2 to the MBR. AFAIK, this should work with other distros as well. You have to chroot into arch then run grub-install to do this.

https://wiki.archlinux.org/index.php/GR … ode_region
See the following Fedora bug report thread for some more info on configfile (particularly comment #23 and #25)..
https://bugzilla.redhat.com/show_bug.cgi?id=872826
It is not recommended to install GRUB2 to a partition...

Multiple installs of SAM on the same machine

I am trying to install SAM for DEV and QA environments on the same server by doing separate installs.
Has anyone tried to install multiple instances of SAM on the same machine? I've run into errors where the 2nd install will not recognize a new directory server for the policy/configuration settings.
Any help is greatly appreciated!

BI 10g multiple installation on same windows machine

Hi All,
I have a requirement where in I want to install OBIEE 10g twice on the same windows server. Can we achieve this by installing it the second time as another OS User? What are the steps that we need to follow in this scenario?
Most importantly, Is this approach supported by Oracle?
Thank you so much,
Krishi

Hi Krishi,
Yes, I think we can install OBIEE 10g on the same windows box multiple times. However, there is some manual effort needed to change the port numbers of each NQServer, sawserver, javahost,oc4j instances to resolve port conflicts.
I do not remember oracle saying that this kind of design is not supported though.
Hope this helps.
Thank you,

How to fix my computer after multiple installs of same adobe product that I didn't start myself.

I just got done downloading adobe Flash Player, Reader, Air, + one other. When they were done installing I had 4 exe files for flashplayer, all exactly the same, 2 readers, 4 of the other that I can't remember the name. I am wondering why adobe downloads kept loading the same things over and over even though it would say complete and I'd move to next. I have had adobe stuff on my last computer and there have been some places (sites) that suggested I get it for this one(computer) also. But I don't want duplicated files taking space. 4 flash player was aprox 45-60. I'm not on the computer page that I can tell exactly. But in comparing the files, they are exactly the same.(As far as I can tell they are) How can I get them off my computer without destroying my computer, or crashing it. My last computer was windows 95 and it has been a while since I've had it. This one is brand new and driving crazy figuring it all out. I do know what flash player downloaded exe files look like and I 've got 4. Can this be fixed so I'm not waisting space. Thanks V.
p.s. I mostly don't understand that these duplicate versions downloaed time and time again. Shouldn't it be built into software that if it's there already you need to re-install?

"exe" is an executable file. Meaning it is executed by either a double click or a click and pressing "Enter". Installers are therefore, executables.
The files downloaded were "installers" only and will not do anything but install the products in your Program Files folder... which is where the actual applications run from. Since you've already installed the applications, you no longer need the installers.

Can multiple installs of BIPE share same repository?

Hello folks,
I work with EnterpriseOne (E1) and in its latest foundation Oracle released what is called Data Access Driver that allows JDBC connection between BI Publisher Enterprise and EnterpriseOne databases. One characteristic of this JDBC driver is that its initialization files are copied to the BIPE directory structure. The driver allows BIPE to connect to only one EnterpriseOne data source. As far as I know to allow BIPE to connect to a different E1 data source, one would need a separate BIPE install altogether.
Question: Is it possible to have multiple installs of BIPE and have them share the SAME report repository and users?
Thanks
-James Owens

Hi Tim,
When E1 Data Access Driver (DAD) is installed in BIPE, .jar and .ini files are copied to "x:\OraHome_BIT\oc4j_bi\j2ee\home\applications\xmlpserver\xmlpserver\WEB-INF\lib" folder. In tests, I found that in order for BIPE to connect to E1 data sources using DAD, there must be a match between E1 environment settings in one of these ini files (jdbj.ini) and the JDBC connection defined in BIPE. When there is a mismatch the following error will appear in BIPE console window:
"WARNING url mismatchjdbc:oracle:enterpriseone://JDV812"
and DAD debug log will show:
"Requesting a spec in path code and using serialized objects build for path code ...
Unable to get initialize UserSession java.lang.NullPointerException"
In none of my tests I was able to connect to an E1 datasource different than the one set in the jdbj.ini file stored in .../WEB-INF/lib. So even if I create a new JDBC connection in BIPE pointing to a different E1 datasource (environment in E1 lingo), that connection would still rely on the Data Access Driver that reads its configuration from the same jdbj.ini where there will be an environment mismatch.

Best Practices: BIP Infrastructure and Multiple Installations/Environments

Hi all,
We are in process of implementing BI Publisher as the main reporting tool to replace Oracle Reports for a number of Oracle Form Applications within our organization. Almost all of our Forms environments are (or will be) SSO enabled.
We have done a server install of BIP (AS 10gR3) and enabled BIP with SSO (test) and everything seems in order for this one dev/test environment. I was hoping to find out how others out there are dealing with some of the following issues regarding multiple environments/installs (and licensing):
Is it better to have one production BIP server or as many BIP severs as there are middle tier form servers? (Keeping in mind all these need to be SSO enabled). Multiple installs would mean higher maintenance/resource costs but is there any significant gain by having more autonomy where each application has its own BIP install?
Can we get away with stand alone installations for dev/test environments? If so, how do we implement/migrate reports to production if BIP server is only accessible to DBAs in production (and even real UAT environment where developer needs to script work for migration)? In general, what is the best way to handle security when it comes to administration/development?
I have looked at the Oracle iStore for some figures but this last question is perhaps one for Oracle Sales people but just in case anybody knows... How's licensing affected by multiple installations? Do we pay per installation or user? Do production and test/dev cost the same? Is the cost of stand alone environment different?
I would appreciate if you can share your thoughts/experiences in regards to any of the above topics. Thank you in advance for your time.
Regards,
Yahya

Your data is bigger than I run, but what I have done in the past is to restrict their accounts to a separate datafile and limit its size to the max that I want for them to use: create objects restricted to accommodate the location.

App Store consistently fails to update apps - but shows multiple installs

The App Store app on my MBP running OS 10.9.2 consistently fails to install software updates, and shows multiple installations in the Updates "log". I've had to reinstall the OS to get to 10.9.2 after multiple failures (with corresponding entries in App Store Updates and incessant hanging at install), and had to troll around the Apple Support Communities to find a URL for Safari 7.0.3 after it also showed falsely as having updated.
Anyone have an idea about what is going on? Missing good old Software Update.

Hi Eskimo Boy,
I have he *EXACT* same issue. I even reinstalled Mavericks completely from scratch and tried TONS of other things.
What I tried so far is (incomplete list):
Set up new user and tried to update => failed.MAS consistently crashes when launched under the new user. => no solution but rather an additional problem => failed.
Tried to update in safe mode => failed.
Tried to reinstall Mavericks => failed.
Tried to reinstall Mavericks and migrate all user data from Time Machine backup => failed.
Tried PRAM reset => failed.
Even tried the highly overrated check permissions => failed.
Whatever I try, I just can't update iBooks from 1.0 to 1.0.1 and Safari from 7.0.2 to 7.0.3. If you have any solution, then please let me know.
Cheers, Paul

Are we allowed multiple installs of Appstore apps?

I want to install my copy of FCPX on my wife's MBP. Is this legal? When I login to my Appstore account from her computer and try to download, it opens the billing page again, and I'm worried we're going to be charged another $300. I've read mixed opinions on this subject and am hoping someone can provide clarification. Are we allowed multiple installs of Appstore apps?

You can download and install purchased apps to all your Macs providing you use the same Apple ID.
Downloading past purchases from the App Store, iBookstore, and iTunes Store

Multiple installs of runtime engine?

Are there any problems with multiple installs of LabVIEW 7.0 runtime engine.
That is, if I create an executable application with the runtime engine installer present and distribute it to a person who already has the 7.0 runtime engine installed, does this present any problems? Will the runtime engine actually be installed the second time? Will there be multiple entries in the Windows add/remove list?

The installer is designed to work that way. Multiple installs of the same version of the runtime engine should only increment the reference count on the files. When you install your built application you will not see an entry for the runtime engine in the Add/Remove Programs (ARP) list.
If you are familiar with MSI terminology, this behaviour is because the LV RTE that is included in your installer is just the merge module not the MSI. When you install the LV development environment, the RTE is installed from a separate MSI. Because your built app installer will use the merge module, the only way to uninstall the RTE will be by uninstalling your app.

Error by moving out a multiple installations

Hi cracks,
Im quite new in the ISU biz and already meeting quite difficult problems :
We have a partner with multiple installations. This partner was moved out with the online transaction as usual and the invoice has been done.
All looked allright but as a new partner was to be moved in on the same installations, we saw that only one installation has been moved out, the other one is still linked with the partner.
We tried to move out the contract but had then the error-message EQ243 saying that move out has allready be done allthought the moving date is still blank
We couldnt canceled the move out as we have an error-message EQ152 saying that the moving date doesnt match the moving date from the first contract (31.12.9999)
So we are now in a deadlocker situation
Tks for solutions
Vic

Dear Vincent,
It look like that 1st of all you have to solve your data incosistence on your system. Look for OSS notes, that describe your problem, you can use the error Messages Code+Number has search criteria.
You can't find anything relevant, create a OSS Message, ASAP and wait for a reply. Give the best detailed information to SAP when you send the message, in order to save time. After this issue is solve you can concentrate on doing the Move-out. Use EC55E, if you are using ISU 464 or above.
KR,
AAL!

How can I print multiple copies of same photo onto one page on iPhoto 9.5.1?

How can I print multiple copies of same photo onto one page on iPhoto 9.5.1? I was able to do it on the old iPhoto, but can't seem to be able to do it on the new iPhoto. Grrr...

Photos does the same thing.... Only workaround I can come up with is to create a template in Pages and copy & paste.

How to restrict login for multiple users having same Role

Our Web Application is deployed on Tomcat 5.5
The requirement is ?
There are roles in application like "operator", "admin"?
There are multiple users created for each of the above role.
When one user of "operator" role is logged in, then
It should not allow to login for another user of "operator" role.
Also, if user did not log out & application gets close, then
It should not allow to login for another user of "operator" role.
Also, it should not allow to login for multiple requests of same user
(using another browser instance...)
Is it possible using session object?
But, using session object, it will create separate objects for different users,
So here I will not be able to restrict session object creation rolewise.
Also, how to retrieve these multiple session objects created for different users on server?
If anyone is having the solution please reply as soon as possible,
Thank you.

To tell you the truth, this is a stupid requirement. It must be an extremely fragile application.
In any case, you will have to write your stuff for that. Probably a filter that on login, logout, and session expiration checks, makes, or removes entries in a DB (using a synchronized resource to prevent race conditions) or possibly even simply in an application context object.

How to update software on multiple iPhones using same iTunes account?

How to update software on multiple iPhones using same iTunes account?

SeanB15 wrote:
Here are more details on my situation which should help clarify things...
I purchased three iPhone 4 models back when they first came out (for my family) that all share the same iTunes account for access to apps and music, but each phone/user still has his/her custom contact list, email accts, and select lists of apps and music from the one iTunes acct library. The problem is (as I understand it) that I can only update the software on one of the three iPhones – the primary phone I used to setup the iTunes acct without wiping out the separate contact lists, etc. As it stands today... the first (primary) iPhone associated with the iTune acct has been updated with the latest software version 5.1.1 and sync'd up with all the apps, music, etc from the one iTune acct, while the other two iPhones are still running on the original software version 4.0.2 and are experiencing problems now. I was advised by AT&T back in January that it would be necessary to setup separate iTunes accts for the second and third iPhones in order to receive system updates and still be able to manage separate contact lists, etc. If I go this route, I assume we will lose all the apps on phones #2 and #3 that we have been "sharing"... correct? Since this AT&T advice was prior to iCloud coming out, would iCloud be a better solution or at least part of the solution? I really don't yet understand how iCloud works. Hopefully, one of you can help me??
we have 2 iphone 4's synced to the same itunes account for apps and music since the day we bought them, but each has a different icloud acct. they have both been updated on the same itunes account with every update that has come out since we bought them in december of 2010. nothing on either phone has ever been lost or duplicated. having said all that, maybe i'm missing something here, but we have had no problems. we do have itunes setup to sync manually. i do believe i'm a piker compared to lawrence finch, but i'm just telling you what happens in my house. maybe check with apple? is there a store near you?

How to use/sync single data (file) across multiple instances of same application

Currently we have an application (a diagram editor), that have the ability to save and load (serialize) its state in a xml file.
Now we want this application to behave like Microsoft OneNote application. Where multiple users have the ability to access the same file.
Later we may also need to enhance with other things like, (1)what is changed and who changed it, (2)option to resolve conflicts if any.
I came to know about sync framework to resolve this. so far, i have not tried it.
All i want is,
Virtually single file should be edited by multiple instances of same application.
We need a dll (sync framework) that does following
It takes complete responsibility of file handling.
Using this dll, each instance of the application will notify their own changes.
Each instance of the application should have the ability to detect the changes that is recently made (when, who, what are the changes).
My question:
Will sync framework be suitable for this requirement?
If so, is there a demo application that represents this?
- Jegan

Seems like I have found the solution.
In the taskflow there is a property named data-control-scope and I set it to isolated instead of the default (shared) and this seemed to do the trick.
I can now have two instances of the same taskflow running with different ApplicationModules

Multiple copies of same emails

Hey,
My problem started few days ago, I received multiple copies of same emails (about 5 copies/email). Now I tried to delete those copies using the plugin (Remove multiple messages) but it doesn't seem to delete. Still shows same amount of emails (about 35000), about 28000 needs to be deleted, in my inbox folder.
So when I try to get new emails, it says hard-drive is full etc... it isn't full. Webmail works great, but only have the latest 7days emails.
I'm using POP. please help to fix this fast.

Were you able to resolve this problem? I have the same issue, but on a macbook pro.
