[JTA_Start_0]Exception getting connection for Oracle DB

Hi All,
I am facing a problem when I am going to insert data in a table (Oracle DB) using JTA Command Action block. I have deployed the Oracle JDBC driver and Configured the data source in http://<server<:port>>/nwa->Configuration Management -> Infrastructure. But when I am trying to insert data using the JTA Command Action block for inserting data in a table it is throwing error.I am running with XMII 12.1 SP5 and Oracle 11g.
Here is the error details.
[ERROR] [JTA_Start_0]Exception getting connection for jdbc/ODS_ORACLE_SBX was ResourceException occurred in method ConnectionFactoryImpl.getConnection(): com.sap.engine.services.connector.exceptions.BaseResourceException: Cannot get connection for 0 seconds. Possible reasons: 1) Connections are cached within SystemThread(can be any server service or any code invoked within SystemThread in the SAP J2EE Engine) or they are allocated from a non transactional ConnectionFactory. In case of transactional ConnectionFactory used from Application Thread there is an automatic mechanism which detects unclosed connections, 2)The pool size of adapter "ODS_ORACLE_SBX" is not enough according to the current load of the system . In case 1) the solution is to check for cached connections using the Connector Service list_conns command or in case 2), to increase the size of the pool.
Note: ODS_ORACLE_SBX is the Data source name which I have configured.
If I increase the min pool size from 0 to 5 or more than 0 then Data source is getting red means not Available.
Can anybody provide any help.
Thanks in advance

You set up your Oracle DB connection by following the path 'xMII Menu -> Data Services -> Data Servers -> New'.

You don't need a DSN if you use Oracle's JDBC driver.

Can't Create the ODBC connection for Oracle 10g

Hi,
I am working with Oracle 10g Database Release 2 in windows XP professional. I am trying to create an ODBC connection for oracle but become failure because its generating the following errors:
system error code 998
could not locate the setup or translator library
Please help me how can I solve this problem and create the ODBC connection for oracle 10g database.
Best Regards,

The odbc driver config routine will search directories listed in PATH variable for necessary libraries (Client dll's). If some library fails to load (from e.g. oraoci*.dll or oraclient10.dll) it will probably error out, as in your case.
Are you creating the odbc dsn on the databse server host or on some other machine? I.e. are you using the db host as a client or not?

JDBC Connection for Oracle

Hello Experts,
I'm having some trouble getting a JDBC connection to work correctly and I am in need of some advice.
Background:
I have setup a test Portal 7.00 SP14 with an Oracle 10.2.0.2.0 database on a Windows 2003 X64 server. The Portal system was up and running and connecting to a WAS6.20 systems. We do not have BI or XI in our landscape.
I needed to connect to an Oracle 10.2.0.3.0 database from visual composer to read some data from tables to do a proof of concept. From what I understand this connection will be a JDBC connection. I have setup a new system using the JDBC template, assisnged an alias, and entered the connection URL . I was unable to connect.
I read that I need to add the driver using Visual Composer. I did so with the following instructions:
Install JDBC Driver
Start the Visual Administrator
Logon at WebAS
Open: Server, Services, JDBC Connector, Drivers
Choose Create New Driver or DataSource on the toolbar
Specify an arbitrary name for your driver entry such as OracleDriver and click OK
Now search for the Oracle JDBC Driver JAR file on your local harddisk.
I restarted the Java instance with SMICM after completing this task Java will not start. Is there anyway to roll back that change to get Java back up and running?
Also is there a better way to go about making this oracle connection?
Best Regards,

Hi,
although [this guide|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/92d80512-0a01-0010-32a3-cd3735bd9275] is for Visual Composer I find it very helpful in setting up JDBC connections to databases. There is a very deltailed section about setting up a system to a MS SQL Server and the relevant data if you want to connect to Oracle:
4.2 BI JDBC Connector to Oracle
Located at:
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html
Driver: oracle.jdbc.driver.OracleDriver
URL: jdbc:oracle:<drivertype>:@<database>
jdbc:oracle:thin:@myhost:1521:orcl
Hope this helps,
Holger.

Could not get connections for 2 databases at the same time

Hi, I have a session bean which calls 2 entity beans in one method. The 2 entity
beans are located in different databases (different datasources and different
pools). When running, I got the following error:
Couldn't get connection:
java.sql.SQLException: Connection has already been created in this tx context
for pool named iitga_jdbc. Illegal attempt to create connection from another pool:
iitdbmap_jdbc
It seems WebLogic only allows one database connection within one method.
Thanks,

Hi Henry,
If you want two beans bound to different database, you need
to use XA pools with TXDataSources because in this case you
have a distributed transaction.
Set up you pools using XA drivers and make sure you use
TXDatasources.
If you tell us which database you use we may come up with
sample pool configurations.

I have internet service on iMac but cannot get connection for Blu ray with airport express.

Why am I not getting internet connection for blu ray on tv with airport express?

Which exact model of the AirPort Express do you have?
Did the Blu Ray player connect wirelessly to the Express before or has it never been able to connect to it at all?

Hello,
I bought this Palm TX more than a year ago and although my numerous efforts, still can't get connected to the internet. Would anybody tell me how to get connected in simple steps please?
Please note the following:
- My laptop uses Windows Vista and WiFi enabled
- I am connected to broadband internet through a normal (not wireless) router
- I don't have any home networks
Thank you
Post relates to: Palm TX

The TX is designed to connect to a wireless network. Wifi is built into it for this purpose, and is very easy to use! Wireless routers can be found for around $30 these days.
Since you have no wireless network, you are limited to connecting via BlueTooth through a cell phone, or via the Hotsync cable to your computer. The latter can be accomplished by purchasing a program called Softick PPP from softick.com. (You can also use BlueTooth to connect if your computer has BlueTooth built into it.)
I have connected mine through a cellphone and with my wireless network at home, but never via the cable. It just didn't make sense to me to use my TX when a real computer is 3' away...

Not getting connection with Oracle 10g

Dear All,
I have installed oracle 10 g on linux , but when I want to connect it gives error msg like this
"Firefox can't establish a connection to the server at 127.0.0.1."
Please give me reply

user8451897 wrote:

"Firefox can't establish a connection to the server at 127.0.0.1."What do you expect to access via HTTP on localhost (127.0.0.1)?
Are you looking for Oracle's Enterprise Manager (OEM)? Are you looking for Oracle's XDB (XML database's webdav interface)? Are you looking for Apex (Oracle's Application Express)? Something else?
Installing also does not mean that you have created any of these services. You typically needs to run dbca (Data Base Creation Assistant) to create a database instance first (which will also setup OEM for you). OEM, XDB and Apex also do not run on tcp port 80 as that requires root privs that the Oracle processes do not have.
So you need to explain exactly what you are doing and what you are expecting.

I have installed on my pc Oracle 11g for windows 7 home edition 64 bit. Usually I use Navigator to develop
or manage my DB, Navaigator 3.0 can be use with a 64 bit client? I have some problem with my previous edition.I assume by "DB Navigator" you mean "SQL Developer" because that's what this forum's about. Or if it's the Jdeveloper
addon - go to the jdev fora.
What's stopping you going [url http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html]here and downloading the x86_64 version?

Where can I get documents for Oracle?

I only have Installation Guide and Administrator's Reference for Oracle 8i. I want to particularly learn how to use tools of Oracle 8i. Where can I get documents for them?
Thanks for your help,
Xu

The rest of the manuals used to be included on the same CD with the product software, but no more. I don't think you can download the complete documentation set (although you can browse it) but you can order one of their CD "packs" and a separate doc CD is included in that. If you get it under their evaluation/development license, it's just a media/shipping charge--something like $35 for the whole "pack."

Create database connection for oracle ver.8.1.7.4 unsucessful

I trying create a database connection with jdeveloper 11g to db oracle ver.8.1.7.4, but the connection return error "Test failed: Unsupported Oracle database version". I selected connection type: "Oracle (JDBC)" and initially selected driver: "thin", after exchange to driver: "oci8", but return error: "Test failed: no ocijdbc11 in java.library.path". Created on menu > Tools > Preferences > JDBC driver options a new driver: "some.jdbc.Driver" pointing to Driver class: "some.jdbc.Driver", library: "oracle.jdbc.OracleDriver", class path: "c:\...\oracle\jdbc\lib\ojdbc14.jar".
Tried to create with this driver with the option "Generic JDBC" pointing to this driver created and using jdbc url: "jdbc:oracle:thin:@//255.255.255.255:1521/ServerId", but return error: "Test failed: Driver class not found. Verify the Driver location"
Now, i don´t know to do!!!

John,
i have the data corporate in this DB in this version. I have already tested with the oracle JDBC driver: "ojdbc14.jar" and works in the "Eclipse" IDE, but i want to use with jdev, understand? Can i test only with this jdbc driver if i set "generic JDBC"?, because if i set "oracle JDBC" this driver is pointing to oracle 11g driver. Is there a "step-by-step" to set this correct procedure? I cannot set "oracle JDBC" of list because the driver class is disabled.

Cache connect for Oracle

We have an application which calls PL/SQL stored procedures in an Oracle 9 Db. Is there any way to use the cache connector for Oracle where the application will use the TT DB instead of the Oracle DB without needing extensive changes to the application?
Any help is appreciated!

Hi user487815,
The TimesTen IMDB does not support PL/SQL stored procedures. For your application, you should select the performance critical procedures and convert them to either ODBC or JDBC SQL calls.

path d:\jdk\lib;d:\jdk\bin;c:\windows\command;C:\temp\BIN;c:\temp\jdbc\lib\classes111.zipYou've added classes111.zip to your PATH, not your CLASSPATH.
Add it to your CLASSPATH using:
set CLASSPATH=%CLASSPATH%;c:\temp\jdbc\lib\classes111.zip
then try to compile/run again.
