How can we achive active/active cluster setup with Oracle

Hi Experts,
How can we achieve active/active database setup with oracle WITHOUT USING RAC.. As far as I know it's impossible (unless I'm wrong)..
We are using Oracle 11.2.0.1 64bit on Windows 2008 server. We deployed Oracle FailSafe but that's more of an active/passive solution based on a windows cluster.
The other solution we were thinking about is to use DataGuard and replication.. two servers.. the oracle instance running on one server generating logs, and the other server receive the logs and apply them to the physical standby db.. Still, this is not a real active/active setup.
So, is it possible to run 2 servers in an active/active cluster and have the oracle database in an active/active setup or have the instance running on multiple nodes (at the same time)?
Thanks

Let me give you a brief explanation of what the situation is and you can be the judge..
My client have four databases with the smallest one being 20GB and the biggest around the 35gb (SGA 750mb to 1.4gb (Tiny by DB standards) and probably on a normal day, you can run all four of them on a decent desktop).. The DBs are used to keep track of people information. Through out the year, the databases are almost sitting idle, and by idle I mean, the odd update here and there, the odd report..etc. No hard real processing of any sort. Two days of the year (end of year) we have all the operators consolidating records and what's not and they will be pounding away entering data and updating the tables - with hourly reports that goes to 3rd parties. The client expects a 99.99 up time and availability during those 2 days.
Now, tell me, How can I justify using RAC and spending hundreds of thousands of dollars in licensing and what ever extra costs introduced by the complexity of the environment for the above scenario knowing that I don't have any real use for RAC for 363 days of the year; and we MIGHT need it for 2 days of the year? This is the dilemma we're facing.
Thanks

Plz help: how can i index multiple directories including pdfs with oracle text??

problem:
i habe several subdirectories with pdf files which must be indexed by a fulltext index.
.../dir/
sub_dir1/
1.pdf
2.pdf
sub_dir2/
3.pdf
4.pdf
it's possible that other users create new subdirs.
try #1:
i tried to update the FILE_DATASTORE parameter PATH with the concatenated directory list
i.e.: (.../dir/subdir1:.../dir/subdir2:...) and updating the index.
that fails, because the directory string is too long (1637 chars)
try #2:
i set the FILE_DATASTORE PATH parameter to the basedir
i.e.: ('.../dir')
now i generate a list of all pdf's including the subdirectories to store them into
a new table.
i.e.: '12345', 'subdir1/1.pdf'
'23456', 'subdir1/2.pdf'
this one fails, 'cause it seems that the database uses some kind of basename() function to
get the "filename_only" part of the table entry 'subdir1/1.pdf' => '1.pdf'.
so, the db fails to open (and indexing of cause) the file.
how can i solve this prob?
thanks in advance!!!
best regards.

If you need to use multiple directories, you'll need to put the full directory and filename into the table, and not use the PATH attribute at all. PATH only works where all files are in the same directory (though you MAY find you can use more than one directory on certain OS's).

How can OS X Server email be setup with hosted email?

We are a small business with our email hosted by an ISP. We are happy with this arrangement and don't want to bring email in-house. However, we would like to be able to setup email (on OS X Server) so that we can access shared email accounts (eg. info@... and sales@....) from any Mac on our network.
I know we can setup each Mac to access the hosted email account but this is not ideal because when one of us reads an email its marked as read on the hosted server but if the email has already been sent to the second client it will not show up as read there. Likewise, we can't see each other's replies or saved mail because these are saved in the mailbox on each Mac client. Whereas, if the Mac clients were both reading the shared email account from the same mailbox on the OS X Server, this problem would be eliminated.
I was thinking that the OS X Server email would enable us to do this but can't work out how.

Camelot - thanks for your reply. I'm not sure though if I posed my question clearly/correctly though.
I also work with a company who use Outlook on Windows and they have recently setup something similar to what I'm looking for:
a) they have Public Folders in Outlook - can Mail do this?
b) they have setup Outlook in I guess a relayed sort of way, whereby the hosted mail is downloaded by the Outlook server and each client then reads from their mailboxes on the server and replies via the server back to the hosted email. This has a couple of advantages (eg. only have to setup the hosted email details in one place, rather than on every client) but in particular it means that when on their network you can logon from any computer and open your local mailbox to read email, see your saved emails & replies (which aren't all saved on the hosted email), etc.
If OS X Server mail could do either a) or b) I think it would give us the functionality we want. With b) we could access a mailbox on the server from any client rather than having to duplicate mailboxes on each client (and hence them getting inconsistent).

Try looking in the bdump directory, the alert file. The actual path should be in your init.ora or config.ora parameter file.

How can I render an active link (yrl) within a UIX/XML page

How can I render an active link (url) within a UIX/XML page.
How can I get <jbo:ShowValue> to work in UIX/XML, or is there another way?
Bill G...

It may seem strange, but the <contents> of <rawText> aren't actually
raw - it's only the "text" attribute that's raw. (It seems strange because
it is. Ah well.) This is different from UIX JSP.
So, try something like the following:
<bc4j:attrScope name="Notes">
<contents>
<rawText text="<a href=""/>
<rawText>
<boundAttribute name="text">
<bc4j:attrProperty name="value"/>
</boundAttribute>
</rawText text="">"/>
Some text in the link.
<rawText text="</a>"/>
</contents>
<bc4j:attrScope>
Thankfully, this will be much simpler in 9.0.3, when the following
will work:
<link text="Whatever you want">
<boundAttribute name="destination">
<bc4j:attrValue name="Notes"/>
</boundAttribute>
</link>

I have powerpoint for Mac on my imac. I can't seem to get the active text box function to work like it did on my PC. How can I insert an active textbox into a presentation that will allow me to type while presenting?

I have powerpoint for Mac on my imac. I can't seem to get the active text box function to work like it did on my PC. How can I insert an active textbox into a presentation that will allow me to type while presenting?

I've gotten a little further on this. The dynamic select is
working fine. It's the "a href" code that isn't. I'm wondering if
someone can look at this line and tell me if it's okay to build the
query string this way. The storeid comes through fine but I'm still
not getting the employeeid value to pass. Here's line that's not
working:
td><a href="registerStoreCust.php?storeid=<?php echo
$row_storeRS['storeid']; echo "&employeeid="; echo
$_GET['employeeLM']; ?>">Register
Customer</a></td>

Moving adobe 9 standard from 1 machine to another. How can I find the activation code on the old machine to activate on new machine

moving adobe 9 standard from 1 machine to another. How can I find the activation code on the old machine to activate on new machine?

You didn't really clarify much, just repeated the same question. First of all, Adobe is a company with many products.
Are you talking about Adobe Acrobat? If so you need to deactivate it on the old machine and then use enter the serial-number (as described) when installing it on the new machine. It will then activate itself automatically over the internet. Just keep in mind that Acrobat 9 is not compatible with Windows 8 and to make it compatible with Windows 7 you have to update it to at least version 9.2 after the installation.

You are allowed to have two machines with activated installations, so if you only had one installation, you still have the option to install on a second without doing anything further than that. If you originally downloaded the purchase thru Adobe then you might find a download link available in your Adobe account online. You can also download thru the following page if you can find your version:
Download and Installation Help -
https://helpx.adobe.com/download-install.html
You can have the first installation deactivated to free up the activation and have it available for another machine again as well. YOu need to contact Adobe Support thru chat for that. For the link below click the Still Need Help? option in the blue area at the bottom and choose the chat option...
