Accessing any external database

How can I connect to any external database from portal.

To further dd_Ram's question..here is our dilema. We want start exploring the use of native Oracle Portal Portlets to replace some of the Discoverer reports we have built. We have come across a ton of limitations/bugs/enhancement requests (whatever oracle wants to spin them as) using the Discoverer > Portlet Provider integration. We are evaluating Report Builder Portlet vs. Omni Portlet as an option. The report builder portlet gives us extra functionality and control than the omni portlet does. We have configured the omni portlet to connect to our ERP database by creating a new connection. What we would like to explore, is if the Report Builder Portlet is only connected to the Portal Repository database, or if there was a configuration to possible point it towards another database directly.

Connection to external database

Hi All,
we have an requirement to connect SAP R/3 to external database which is oracle and java tool for data uploading.
One of our team abaper requested us to establish the connection.
When explored , i got some info on DB11 and DBCON table.
I created the connection with the DBM user control and SAP user SAPR3.
Please let me know how to test the connection further and details on connection to external database from BASIS point of view.
Thanks

Hi,
Using transaction SE11, create a table (ZTABLE) with the same fields as the table in the external database, make sure that the type and lengths of the fields are identical.
Using transaction SE11, create a view (ZTABLE_VIEW, projection view) using BASIS table ZTABLE
Using SVRMGRL>
create dblink REMOTE_DB as connect to remote_user identified by password; (database link created)
drop table ZTABLE; (table dropped)
create synonym ZTABLE for ZTABLE@REMOTE_DB; (synonym created)
Using transaction SE16 , type in ZTABLE_VIEW and hit RETURN
Enter value in key fields and hit execute. (displays rows from the remote table)

How to access tables/views of an external database provider..

After much trouble I finally managed to setup a second Database Provider that doesn't display the "0 out of 0 connections are good" error by filling in the "Configuration Class" field with "intradoc.server.DbProviderConfig".
But now the problem is actually accessing the tables/views in my newly configured external database provider...
In the Configuration Manager applet when I try to add a new Table or View it only lists the tables contained in the schema of the SystemDatabase database provider (the original one), I've tried running Queries via components trying stuff like SELECT * FROM provider_name.table_name and other similar but obviously it doesn't work...
So... with that said, I just want to know how I access tables or views in my "supposedly" well conected (15 out of 15 connections are good, no errors on the Test Query) Oracle external Database Provider - After searching I was unable to find any information regading any post-provider-setup actions in the Content Server documentation - Does anyone know how to do this?
On a side note, if the database is SQLServer instead of Oracle, with the same configuration and apparently no errors on the database side (other clients access it well) the Query Test of the new database provider returns the following error:
"The provider 'TestSqlSrv' is in error. Unable to create database connection for JDBC:ODBC:SqlSrv. Unable to create result set for query 'select * from dummy'. Invalid Fetch Size Unable to create result set for query 'select * from dummy'. Invalid Fetch Size java.sql.SQLException: Invalid Fetch Size".But I won't even go there yet.... for now I would settle with just knowing how to reference information in the Oracle external database provider...

if you are able to, pick up Bex Huff's book the Definitive Guite to Stellent Content Server Development (amazon link: http://www.amazon.com/Definitive-Stellent-Content-Server-Development/dp/1590596846/ref=sr_1_1?ie=UTF8&s=books&qid=1196365101&sr=8-1)

Access external database views on different tablespace

Hi everybody,
I'm trying to access a external Oracle database (dbcon entry is set successfully) and read data from a view wich does not belong to my schema. In other IDEs the statement is simple:
select *
from schema.view
In ABAP the code looks like this:
SELECT *
FROM ('schema.view').
But ABAP splits this literal into two pieces and so I get an error message view does not exist.
Any idea how to correct the FROM part?
For your information. I tried to link the view on the oracle database over a synonym to access the view in the other schema. Normally this works fine, but synonyms will not be publicated to SAP so I can't read the data furthermore.
Thx so far!
Sincerely,
Bastian

Instead of accessing the views on an different schema I created my own views.

I have all of my data from my old macbook pro in an external hard drive. Basically it's my old Macbook hard drive with external casing. It was working fine before when retrieving files using my new macbook air, now I can't access any files?

I can't access any of my files, photos, anything form my external hard drive... It worked before now when I plug it in the light comes on, but it doesn't even show up as an external drive, so I can't access anything, I'm worried I have lost everything...

Huge mistake was only having ONE copy of your data OFF computer,
most people do it, and its just horrible and the typical reason for serious data loss.
Likely you have a very common failure (extremely common actually) called SATA bridge card failure, which would be "good" news,
read about same here:
Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD
Never again let yourself have LESS than 2 copies of your important data off-computer, ever
1. verify the external HD doesnt show up on another Mac
if same, you have about a 8 in 10 chance its SATA card failure.......... easy to fix.
The great news at the end of the tunnel of an apparently failed or failing external hard drive.
When checked on another computer, and with no need for spending money on data extraction expertise or software, the very likely case is that your external USB or thunderbolt HD is in fact fine, and merely the card interface, or SATA bridge card has failed or is failing. Keeping a HD dock around handy, or cheaper still a $20 hard drive enclosure or a SATA to USB connector can be a real life saver in getting your drive back to use, when the drive itself is fine, and merely its interface card has gone bad.
The SATA bridge card inside a USB external HD has a very high failure rate in general
Typical SATA bridge cards as seen inside a 3.5" external HD with power input (#1), and 2.5" SATA cards (#3, #4, #5)
What are the realistic odds your HD is perfectly fine?
There are no hard facts whatsoever, especially since so many people discard their assumed “dead/faulty” hard drives, but a good educated conclusion from years of examining and seeing this issue is that for hard drives made since 2010, and not dropped or generally abused, is that a minimum of 50% conservatively are perfectly fine! I personally estimate however that it likely approaches 60%+.
Considering how many external hard drives ‘fail’ (rather the SATA bridge more than half the time) each day, that is a very high number of perfectly fine HD that are tossed!
This is especially common with 3.5” desktop HD that are connected 24/7 with power and see a lot of data transfer. People wrongly conclude that “X” mfg. just made a defective drive, when in fact their 3.5” drives inside the plastic enclosure is 100% fine. I have personally seen well over 200 of these dead SATA cards and additionally seen 3 fail within a one hour span of doing a large data copies.
One of the very reason pros use bare HD as inserted into HD docks is not just the saving of space and the need for endless USB cables, but the elimination of the need for this high failure-rate part.
While the shapes and sizes vary somewhat on SATA bridge cards, they all serve the same purpose and have likewise failure rates
What exactly is the SATA bridge card in your external HD?
In the middle to late of 2009, most all external hard drives both in 2.5” and 3.5” reached the shelves in SATA III. These small SATA cards or "bridges" are used to translate between the hard drives’ interfaces and the enclosures' external ports (USB, Thunderbolt, Firewire). Additionally these small bridges not only transfer power but also of course the data. Unfortunately these SATA bridge cards have a very high failure rate as they are burdened with shuffle power and data.
Literally these little unreliable and fragile cards are the power conduits and the nervous system for all external HD data transfer.
SATA card as found inside a typical USB external hard drive
The assumption that the hard drive is bad when its not!
Countless 1000s of good external hard drives are thrown away each year because the owner thought the HD was bad when it fact it was the SATA bridge card which had failed. This card is removed in a matter of mere second once an external USB HD is cracked open from its plastic casing to reveal the bare HD and the attached SATA card which attaches between the HD and the USB cable.
To complicate this problem, even many computer professionals do not know that there is a very easy solution to the “failing or dead HD” issue since the hard drive itself is very likely just fine. Its astonishing that so many highly educated computer repair persons are unaware of this high-failure part, but this is mostly due to the fact that they do not juggle 100s of hard drives and know that of the iceberg that is a “external hard drive failure”, the mostly unseen majority are not a HD failure at all, but a bridge card failure.
To add to this great misunderstanding is the fact that people assume that "likewise symptoms seen on an external HD are the same as seen on an internal HD, therefore also the external HD must be bad". This is a compositional fallacy of logic. Since internal HD do not have a SATA bridge interface, to conclude similar symptoms "indicate the same failure" is misplaced and incorrect.
This is all not to say that HD do not fail, they do indeed, and I have seen many 100s of dead and failing hard drives. Hard drives even under ideal conditions have a life expectancy of around 4-8 years due to ferromagnetic depolarization from entropy. But of the mountain of symptoms that are seen as “hard drive failures” in comments, posts, and hearsay, half or more of these are not a HD failure at all.
Once your rescued hard drive is removed from the bad SATA card
You have several options, but the purchase of a $20 HD enclosure is one option, another is having a HD dock, however this eliminates the former portability in a 2.5" small HD.
Remember that 3.5” HD require power, which means you need either a HD dock, or a powered SATA card kit as seen at top left in the picture below. 2.5” HD get power from the USB port itself.
Just remember that the serious downside to the low cost external HD enclosures is THEY TOO contain these SATA cards, and what is worse the cheap ones will fail, often, much quicker than the original factory one did! In which case it is recommended you buy a quality HD USB enclosure

I accidentally updated iPhoto on my (now) external hard drive and now it won't let me access any of my photos. What can I do?

I accidentally updated iPhoto on my (now) external hard drive and now it won't let me access any of my photos. What can I do?

So, you have two versions of iphoto? One from the old machine and one from the new?
If so, forget about opening with the older version of iPhoto.
For the newer version:
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

This can be done easily with ethernet.
Please follow the instructions strictly.
To make it easier I want you to do this overnight so you can turn off all your current connection to the internet.
Just go to the airport fan in to the top right and turn airport off.
Get ethernet cable and connect the laptop to the TC lan port.. ie <-> ones.
Press and hold the reset on the TC for about 10sec. until the front led flashes rapidly.
Open the airport utility.. go to manual setup and change the wireless to off. (so other people around you cannot join your network of one).
Ignore all the errors.. they won't stop the backup working.
Go to the TM and reselect the backup target disk as the TC.
It should start after 2min and run through to completion.
That is it.. for a backup of many GB it might take a few hours.. so make sure the laptop has power plugged in and the sleep is off.. (on early ones I think this is needed but I am a late arrival to the scene).. sleep doesn't affect later OS.

ACS external database issue

Hi
I have the following issue, user exists on both the ACS and token server authenication is set to external database with no unknown user policy as the user is known to the ACS! this fails authenication error message is CS user unknown... Now if the unknown user policy is set to the external database the authenication works fine this is on 3.3. I have checked for bugs to no avail.
Any assistance would be good...
Thanks MJ

Hi JG
Many thanks for your response, it is configured this way due the documentation below:
Known Users -Users explicitly added, either manually or automatically, into the CiscoSecureACS database.
These are users added through User Setup in the HTML interface, by the RDBMS Synchronization feature, by the Database Replication feature, or by the CSUtil.exe utility. For more information about CSUtil.exe, see "CSUtil Database Utility".
CiscoSecureACS attempts to authenticate a known user with the single database that the user is associated with. If the user database is the CiscoSecure user database and the user does not represent a Voice-over-IP (VoIP) user account, a password is required for the user. If the user database is an external user database or if the user represents a VoIP user account, CiscoSecureACS does not have to store a user password in the CiscoSecure user database.
This is from the following link....

Authenticating Guest Users Using External Database.

Folks, greetings.
Due to the limitations imposed by wlc's database size, we decided to go for an external authentication server.
Since this external database is for guest access, we are considering in using a Linux box with LDAP, along with a web-based application which will be presented to the user for authentication purposes. This way, the user would type in his/her credentials on this portal and the same box would process the authentication.
In such a scenario, we would buid an application for the "Lobby Amabassadors" input the guest data (for auditing purposes we need to enter the user's SSN, passport # or any other official ID), and this application would generate the password to be used during the authentication process.
I've used web-auth before, with the users database loaded on the WLC (local net users). Even using an external web-auth portal, the user is still authenticated by the controller that in turn, will control whether the traffic is to be allowed or not, based on the authentication results.
That's exactly where our question lies: how should we configure the WLAN so that the WLC would receive the access request and forward it to the authentication portal/server? Would it envolve radius?
This same Linux would be the DHCP server for this guest WLAN.
WLC vesion: 4.2.130.0
Regards,
AL

Using the Web Authentication feature on a Cisco wireless LAN controller, we can authenticate a guest user on the wireless LAN controller, on an external web server or on an external database on a RADIUS server. We can configure the wireless LAN used for guest traffic to authenticate the user from an external RADIUS server.
To enable an external RADIUS server to authenticate traffic using the GUI, follow this link.

Pointing to external Database from apex application

Hi Guys,
Is that possible to point to databse exist in another server through apex application ? is there any configuration like that ?

You would make this kind of connection within a schema/database that your Apex instance already has access to, or a different schema, which you would then make available to Apex. Once you have this setup you can reference the external database/tables just like any other table in Apex. You may be limited to which operations are supported on the external data, depending on whether it's an Oracle dblink or an ODBC connector, etc.

How to Link to External Database

I can't figure out a good way to keep track of photos within Lightroom that I submit for contests, sales, etc. I could make comments in the caption metadata field, but that would mess up my caption field and is not that flexible. I could color code, but that's very limited. It seems like the ideal way would be to create an external database with something such as Microsoft Access. Using the Filename as the primary field, I would link it to additional fields, date submitted, where sent to, type (contest, stock sale, gift, etc.), price obtained, published date, etc. Then I could see the history of any given image, run queries for all images submitted to a particular place where amount is > $0, etc.
As this is just a hobby and the numbers are small, I could just enter all the data by hand, but if I ever enjoy a lot of commerical success it would be nice if the database integrated with Lightroom. Ideally the queries run would not only show the Filename, but also show photos, perhaps as a Collection in Lightroom. It seems there must be professionals that track such information. Perhaps there is a third party program that does this. I'd appreciate any suggestions.
Dan

I think Access would be better in the event a given photo is used multiple times. Suppose a particular photograph sold at iStockPhoto.com for $1 on 22 occasions, at a local gallery as a 5 x 7" print for $2 on 14 occasions, as an 8 x 10" print for $8 on 9 occasions, and on one's own web page for $3 on 9 occasions, plus published in Pop Photo on 4/17/03. To make custom fields in Lightroom would be onerous, and it couldn't do the math for you. In Access one could use one to many tables (tblPrintSize, tblWebSite, tblSellerType, etc.) to track this fairly easily. The only time consuming part would be entering each sale if one had a lot of them. Of course one could choose to enter quarterly or yearly sales instead if desired.
Queries and reports would show where one's income is derived, what formats sell best, etc. It might help in tax preparation.
This may be more power than professional photographers would ever want. It's probably a fantasy that won't come true that it will ever be an issue for me, but I like to be proactive on data management before it becomes unmanageable.

Way of External Database Integration with UCCX

Hi
I want to know what are the way of UCCX integration with External Database(Mobile Operator, Banking, Insurance).I only know about DBwrite and DBGet. is there any way out(http, https,SOAP)? They dont want to give me direct access to there Databases.
Sultan Al Arif

One way to do this would be to use the Get URL Document step to request an XML file from a web server.
Upon receiving this request the web server would then retrieve the required data via SQL (fairly easy to do using ASP.NET and IIS), format it in an XML page and return it to your script.
The script would then use Get XML Document Data steps to parse the XML file for the required data.
The organisations that operate the databases with which you want to integrate may have some concerns about the security of this though as the data will not be encrypted in transit.
