Connection to Oracle XE via IIS/ASP app was working then stopped

I am prototyping an application for my new management here so that I can recommend they use Oracle XE.
The connection to the Oracle XE database appears to have stopped working, via an IIS/ASP application I wrote. I can still connect through ODBC using native MS Access to Oracle XE, when logged into XP, its just when I try to log in using the app via IIS I get the following error:
Unable to establish connection to database.
Error information:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E4D)
[Oracle][ODBC][Ora]ORA-12154: TNS:could not resolve the connect identifier specified
It was working for a while, like the whole first week. It might be related to the fact that that I finally rebooted, not sure.
I have tried many, many things. I made the IUSR account an admin on the box hoping that maybe it had just lost access to the local ODBC/TNSNAMES. Right now all the components are local to my development box, from the IIS server to the Oracle eXtended Edition database (XE, free). Like I said, it was working. I did have this same message I believe early on, which turned out due to the fact that my ODBC DSN was a local DSN, instead of a System DSN, which I overcame at that time. But it just started happening again, possibly after a reboot.
I also tried switching to a local MS Access database, and I got a similar message. I moved the Access db to c: root, and it appears to work, so it appears to be a file/directory access issue.
But I'm not sure how to resolve it because I would much prefer to use the Oracle database.
Thoughts?

As far as the connect string goes, I'm not sure exactly what to specify to you.
I am using the default connect string that comes when you install XE.
I.e., "XE".
I suspect this might be a path issue for the virtual account that is used by IIS sessions. As you may know, when IIS runs, it logs the web user into the box using a dummy account, typically prefixed with the string "IUSR".
Although I made this account an admin to the box, I think I may need to add some of the Oracle Client directories to the path which is accessed by this IUSR account. The problem is, the acount, with its password, was set up by default and I don't know what its password is. But I think that I could try to adde Oracle's home path to the default system path, what do you think?
In other words, I don't think the XE connection libraries are available to this dummy IIS account. The strange thing is, it worked for a while, ostensibly till I rebooted.
Know also that I am not using the Oracle Client per se, although I did install it and try it with mixed results. I am just using the Oracle OLE DB ODBC that appeared when I installed the Oracle XE server itself.

Can I connect to an OracleDB via an Android app?

Hi,
I originally resurrected an old long-finished forum thread and attempted to hijack it away for my own issue but a kind forum moderator has split my question away so that it might stand on its own merits (or not). I'll try to remember for the future that if I have a question, I should always make my own new forum post.
That thread was ...
Exception when connecting to an OracleDB via an Android app
Is that possible to connect to other DB from android. I m a trainee and I m trying to connect android with other DB's except SQLite.. if so can anyone explain 1. how to do that, and
2.what are the DB's can be connected with android...
3.What is the concept behind to work it out...
pls explain it a bit detail, as i m learning it would be easier for me to understand the concepts in better way.

Same as what I said in the other thread.
Either there is an IP stack or there isn't.
If there is then you have the same problems with IP stacks as with a desktop in that it must have connectivity from the client to the database. Other than that you just use a JDBC (java only) driver.
If there is no IP stack then you MUST look for another solution or look into creating your own solution (if possible.)

Making connection to Oracle 9i via SQL Plus - Mark

Hi,
I am unable to connect to oracle 9i via dos prompt or SQL Plus.
I installed the satabase on windows.
The SID is obiwan. Please help, already browsed similar topics and its not happening.
Thanks in advance.

The Listener is the process that is listening for incoming remote connections to the DB(s).
Database and Listener have Windows services, and services have to be started. Also, from DOS prompt you can do :
C:\> lsnrctl stat
to see if the Listener is active : the result should be the list of active DB(s).
To connect locally to the DB do the following :
C:\> set ORACLE_SID=obiwan
C:\> sqlplus "/ as sysdba"
The result should be something like SQL*Plus: Release 9.2.0.4.0 - Production on Dom Apr 10 16:58:32 2005
Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.

Connected to an idle instance.
SQL> then it means that the DB is not up. In this case try :
SQL> startup
That way you are connected as sysdba, you can startup and shutdown the DB, create users, and so on. Do not use this connection to create objects (tables, indexes and so on) :
create an user, using the command "create user" (See [url http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/toc.htm]Sql documentation), and connect as that user, for example
SQL> conn scott/tiger
or, at DOS prompt
C:\> sqlplus scott/tiger
If you create a TNS alias, as I said before, you can use that as connection string from DOS prompt
C:\> sqlplus scott/tiger@<TNS alias>
or using SqlPlus in the Oracle menu.

How connect to oracle RAC via the RSG using port forwarding

Hi all,
I got a problem trying to connect to oracle RAC via the RSG using port forwarding .
on command line i sue to connect :
sqlplus 'username/password@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=firstRACnode)(PORT=1521))(ADDRESS=(PROTOCOL=tcp)(HOST=secondRACnode)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=MSDP)))'
but when using port forwarding i forward the port 1521 to a local port and make ssh to the DB node ( as normal with other nodes but not RAC) but it never work with me for this situation
can any one give me a help ifthere is any changes should be done on the server side , or if any one faced such a problem and found a solution
Thanks,
Prathap.

Step 1
Create a ssh tunnel from local machine to remote db server. Forward any local port (should not be a well known port or a port in the private/dynamic port range) to connect to the database server's listener port. If the ssh tunnel is into the db server itself, the connection (port forwarding) can be on localhost (as the Listener should be listening on it). Alternatively use a public IP of that db server.
Example (using OpenSSH on Ubuntu 9.4):
Local server port 1527 tunneled to port 1521 on database server 192.168.0.100 using o/s account johnd (we connect to port 1521 on db server via 127.0.0.1):
ssh -X -f -N -o ServerAliveInterval=3 -L 1527:127.0.0.1:1521 [email protected]
Step 2
Run sqlplus and connect to the local fowarded port on localhost, using the applicable connection settings (e.g SID/Service Name, etc).
sqlplus scott/tiger@"(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1527)) (CONNECT_DATA=(SID=orcl) (SERVER=dedicated)))"Note that the Listener must not hand our connection off - as the case would be when using RAC for example and connecting via a Service Name and not a SID. We need the Listener that accepts our connection to immediately hand us over to the database instance (via either a dedicated server or a shared server dispatcher process).

Private Photos App - pictures not displaying This app was working fine, then suddenly it won`t display any of the photos.

This app was working fine, then suddenly it won't display any of the photos. One day the photos were there, gone the next. It still shows how many photos are there but just shows a white screen. I can't export anything to the photo album. Adding photos to existing folders yields the same result, only white screen displayed. However, I can create new albums and add photos to those without issue. Does anybody know how to recover the "missing" photo" I was going to try reinstalling the app but it's no longer available in the iTunes App Store. Thanks, Tracy

1, you can't at the moment, though with iOS 5 in the Autumn, from http://www.apple.com/ios/ios5/features.html#photos :
Even organize your photos in albums — right on your device
2, by removing it from you synced from and re-syncing. Only photos taken with the iPad, copied to it via the camera connection kit, or saved from emails/websites etc can be deleted directly on the iPad (either via the trashcan icon in the top right corner if viewing the photo in full screen, or via the icon of the box with the arrow coming out of it in thumbnail view)
3, the location of the photos that you synced to the iPad should be listed on the iPad's Photos tab when connected to your computer's iTunes.
4, you can copy the photos from your iPad to your computer : http://support.apple.com/kb/HT4083 . You should also be able to delete them from the iPad as part of the transfer process to your computer, and it's then your choice whether to add them to your sync photo list so as to copy them back to the iPad. Copying them to your computer would allow you to organise them into folders and therefore be able to sync them back into separate albums.
5, I don't use Dropbox either. There are some third-party browser apps in the iTunes App Store that allow you to download pages so that you can view them when offline e.g. Atomic Web (the whole page is saved within Atomic Web, it doesn't place a photo into the Photos app)
6, deleting content should help. If you remove an app from your iPad then you also remove the content that it's got on the iPad - so if you then decide to reinstall it back onto the iPad then you will need to manually add back any content that you want in it. None of the Apple built-in apps (including Photos) can be removed from the iPad

Thanks for your help indicating how I can save my projects and see them for example in an iphone for assurance that data is not lost.

try this.
get back into your router's settings and start deleting devices that are not connected to your router.
you can also delete the ones that are connected - they'll connect again.
on the DHCP side of it, increase the amount of users that can connect/log in to your router.
see if that sorts it out for you.
good luck.

Exception when connecting to an OracleDB via an Android app

Hi everyone,
I am coding an Android app. This app has to get datas from an Oracle DB available on the LAN. So, I use JDBC to connect to the database. (ojdbc14.jar added in my Android Project). I've made 2 classes : OracleDB with the following code (http://pastebin.archlinux.fr/432146) and the "launcher class", JDBCAndroid, with that code : http://pastebin.archlinux.fr/432148.
The program, when it's a simple Java Project is able to connect to the database ; but in an Android Project, as you can see in the pastebin of the JDBCAndoid, there is "some" Exception from the driver.
In particulary, this one :
04-22 08:17:52.509: ERROR/AndroidRuntime(346): Caused by: java.lang.ArrayIndexOutOfBoundsException

Could someone help me to fix this ? Finally, is it possible to connect to an OracleDB from an Android app ?
other details : the server is an Oracle 10g 10.2, and the driver is ojdbc14.jar (version corresponding with the version of the server).
Best regards

That IP is a private IP.
This app is very particular. It'll be use only in a restricted LAN (with the database Oracle in this LAN). So, no connection by the Internet to the database. That's why webservice is not the good solution for me. The direct connection to the OracleDB is, I think, the best solution, but I've to fix this problem...Since I haven't done any mobile programming I can't be sure but that looks extremely unlikely to me.
A mobile/cell doesn't connect to a local network. It connects to a service provider which does a redirect, via the internet. Thus a local (private IP) connection cannot work. (That is what the 'data' fee is for.)
Now if and only if the mobile has a true wireless modem in it then it would need to connect to a lan wireless router which itself was set up to do a local redirect. So two points of failure there: the wireless modem and the lan router. If either is not set up then it will fail.
And if you have a wireless modem on your dev box then you can test the connectivity from there to the database just as the mobile would. To be safe yank your network cable before testing.

Connecting to Oracle lite via VB6

Hello
is there a better way to connect to Oracle 10g when using VB6?
this is what I have:
Under references I am using Microsoft DAO 3.6 Object library
I do have a module where I defined the following public variables:
Public wsOracle As DAO.Workspace
Public cnOracle As DAO.Connection
Public strConn As String
and a function to alllow me to connect to the database:
Function ConnectDB()
On Error GoTo Error_DataBaseError
strConn = "ODBC;DSN=MY_DATABASE;UID=user;PWD=passr"
Set wsOracle = DBEngine.CreateWorkspace("", "admin", "admin", dbUseODBC)
wsOracle.DefaultCursorDriver = dbUseClientBatchCursor
Set cnOracle = wsOracle.OpenConnection("", dbDriverNoPrompt, False, strConn)
Error_DataBaseError:
If Err <> 0 Then
Call ErrorCatching("ConnectDB ()")
End If
End Function
It seems to work but I am having issues, two apps are connected to the same Database one is in power builder y the other in VB6 after a certain time of inactivity I get timed out from the VB app and this gets also into the power builder app.
but if one app is open for a long time it seems to work just fine. any ideas why?
I read that I can use the Oracle Lite 40 ODBC Driver
but I can't seem to find a way to do the call from VB6
any ideas?
any enlightenment will be appreciated

Unfortunately, in 2.0 beta, the Infobus Data Form wizard
connection editor only supported the Oracle Thin, OCI7 and OCI8
drivers. For 2.0 production, Oracle Lite and the JDBC-ODBC bridge
will also be supported.

IPad connects to network, but not internet, and it was working fine yesterday

So yesterday it was working fine, conecting to the internet and the router, then all of a sudden 'Safari cannot load the page because it is not connected to the internet', it was the same for all the apps that needed internet.
My 4th generation iPod touch connects fine and so do other wireless devices on my network, what went wrong and how can I get my internet back!??
I have tried resetting the connectivity settings, resetting the router, adding the MAC address of the iPad to my routers 'Safe List' (which it wasnt on before it stopped working), and tried turning on and off the iPad.
So what can be done to fix this?
Thanks in advance

A lot of hassle for such an annoying problem but I still have no idea why it didn't connect in the first place!?
You found a work-around. Can't argue with success but you have not solved your problem. You should continue trying to get it to work via dhcp and dynamic addressing.

Any ideas?

How does SCAN work?
“When a client submits a request, the SCAN listener listening on a SCAN IP address and the SCAN port is contracted on a client’s behalf. Because all services on the cluster are registered with the SCAN listener, the SCAN listener replies with the address of the local listener (Using SCAN the connection is initiated using the SCANIP, but is established using the VIP) on the least-loaded node (Each scan listener keeps updated cluster load statistics) where the service is currently being offered. Finally, the client establishes connection to the service through the listener using VIP on the node where service is offered.All of these actions take place transparently to the client without any explicit configuration required in the client.”
So, to SCAN Works you must aware:
Server (cluster)
-The service must be registered on Local/Scan ListenerI believe I've done this now but see below.
Database (rac)
-You must use remote_listener parameterThe remote listener parameter I have is:
SQL> show parameter remote listener
NAME                    TYPE     VALUE
remote_dependencies_mode     string     TIMESTAMP
remote_listener           string     rac-scan:1521
remote_login_passwordfile     string     EXCLUSIVE
remote_os_authent          boolean     FALSE
remote_os_roles           boolean     FALSE
result_cache_remote_expiration     integer     0
Cient
-Must resolve all SCAN Names and VIP Names (check with nslookup)I'd made a mistake there. My VIP names were not available from DNS.
-Must access port of Listener
Try it:

Thanks, that document was useful however I don't think I've got it completely right as yet as I have no listener_scan2.

Connectivity of Oracle 9i DB With ASP Application

Dear friends,
Can Any one please help me in solving my problem as follows. I run Oracle 9i Release 2 Database on Red HAt Linux Advanced Server. I also run a web server running on windows 2000 server and IIS 5.0. Now my problem is that whenever i try to coonnect the databse using ASP Pasges it returns me error of the following nature :
1) objconn.Open "Provider=MSDASQL;Driver={Microsoft ODBC For Oracle};UID = kms;PWD=kms;Server=KMS;"
Error Message :
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC Driver Manager] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed
/ORACLE77.ASP, line 8
2)objconn.Open "Provider=MSDAORA.1;User Id = kms;Password=kms;Data source=KMS;Persist Security Info=False"
Error Message:
Microsoft OLE DB Provider for Oracle error '80004005'
Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed.
3) objconn.Open "DSN=KMS;uid=kms;pwd=kms"
Error Message :
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
Specified driver could not be loaded due to system error 5 (Oracle in OraHome92).
My service name is KMS,database name & sid name also is KMS
PLease Help me out of this problem.

You may probably look at the possibility of using Oracle Provider for OLEDB.
You can refer samples on this at following url
http://otn.oracle.com/sample_code/tech/windows/ole_db/content.html
This url also gives links for downloading the software.
