Special DB connectivity for FX, besides JDBC?

I was just curious if there is a particular way we should access data in FX over normal SE. I did read on another site that it might be better to use "Web Services" to access the data via the web than to use a JDBC.
Now currently the first program I am doing will most likely be CLIENT ONLY so I figure that's going to lean in the JDBC or w/e direction,
Whereas the next program will be Client-Server so I figure maybe using Web Services will be better?
I am using currently MYSQL Workbench, and I'm not too sure what filetype I should export it as. I read that "SQL" files have issues in the JDBC(but the article from the ranch was 5 years old so IDk) but there is CSV, and XML, XML(mysql), delimited CSV, JSON, HTML, excel and "tab seperated"
I was thinking the only usable ones are probably CSV, XML, maybe JSON, and Excel? Thougths on what I should export as?
Sorry if some of this is more "Normal" Java, but again not too sure if there is a specific FX route, and if there is something special we should do.
Thanks!!!

Altough i can create a connection using Driver --> JAVA DB (Network), but still doesnt work in Runtime.

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.

Connection Properties for the BI JDBC Connector

Hi
I am trying to configure BW 3.5 java component. In the Connection Properties for the BI JDBC Connector, there are four required properties. (UserName, Password, URL and DRIVERNAME) What should I enter for the URL and DRIVERNAME? I am using Oracle920.
Please help,
JW

I found this info at
http://www.oracle.com/technology/tech/java/sqlj_jdbc/htdocs/jdbc_faq.htm
Oracle is replacing the SID mechanism for identifying databases with a new services approach. This has been available in the database since 8.1.7. JDBC now supports services in the connect URL.
The basic format of a service URL is:
jdbc:oracle:thin:[<user>/<password>]@//<host>[:<port>]/<service>
jdbc:oracle:oci:[<user>/<password>]@//<host>[:<port>]/<service>
Examples:
jdbc:oracle:thin:@//myserver.com/customer_db
jdbc:oracle:oci:scott/tiger@//myserver.com:5521/customer_db

Problem with JDBC Connection for HDB hanadb 02

Hi folks,
Ok I have an instance based on the 7.4 SP5 HANA CAL solution.
But when I suspend and restart the R3 system doesn't start again.
I've followed the instructions in the user guide and can access the backend instance and see that for HDB GetProcessList everything is GREEN, running
while for A4H GetProcessList everything is GREY, stopped
When I try to start the A4H instance I get
Checking HDB database
Database is not available via R3trans
Database must be started first
The messages I found on SCN suggested this might be a license problem with the HANA database, so I tried to follow the install license instructions for the HANA database via the HANA studio, but when I try to open the HDB(SYSTEM) > Properties > Licence, I then get the messages
Error while reading the licence information from system HDB hanadb 02
Reason:
Cannot retrieve JDBC Connection for HDB hanadb 02
So what do I try now?
Any suggestions?
Rgds,
Jocelyn

Thanks Ivanka! That sorted it.
For the benefit of others...the error message was found in the server log files

[XI 3.1] BEST PRACTICE method of Oracle connection for RPTs on Linux

Business Objects XI (3.1) - SP3.
Running on Red Hat Enterprise Linux OS.
7,000+ Crystal Reports 2008 *.rpt objects ONLY (No Universe / No WebI).
All reports connecting to Oracle 10g databases.
==================
In the past, all of this infrastructure was running on Windows Server OS and providing the database access via a Named ODBC connection (eg. "APP_DATA".)
This made it easy to manage as all the Report Developers had a standard System DSN called "APP_DATA" which was the same as the System DSN name on all of our DEV, TEST/UAT, and PROD servers for Business Objects.
When we wanted to move/promote a *.rpt file from DEV to PROD we did not have to change any "Database Connection" info as it was all taken care of by pointing the System DSN called "APP_DATA" a a different physical Oracle server at the ODBC level.
Now, that hardware is moving from Windows OS to Red Hat Linux and we are trying to determine the Best Practices (and Pros/Cons) of using one of the three methods below to access the Oracle database for our *.rpts....
1.) Oracle Native connection
2.) ODBC connection
3.) JDBC connection
Here's what we have determined so far -
1a.) Oracle Native connection should be the most efficient method of passing SQL-query to the DB with the fewest issues and best speed [PRO]
1b.) Oracle Native connection may not be supported on Linux - http://www.forumtopics.com/busobj/viewtopic.php?t=118770&view=previous&sid=9cca754b468fc67888ab2553c0fbe448 [CON]
1c.) Using Oracle Native would require special-handling on the *.rpts at either the source-file or the CMC level to change them from DEV -> TEST -> PROD connection. This would result in a lot more Developer / Admin overhead than they are currently used to. [CON]
2a.) A 3rd-Party Linux ODBC option may be available from EasySoft - http://www.easysoft.com/products/data_access/odbc_oracle_driver/index.html - which would allow us to use a similar Developer / Admin overhead to what we are used to. [PRO]
2b.) Adding a 3rd-Party Vendor into the mix may lead to support issues is we have problems with results or speeds of our queries. [CON]
3a.) JDBC appears to be the "defacto standard" when running Oracle SQL queries from Linux. [PRO]
3b.) There may be issues with results or speeds of our queries when using JDBC. [CON]
3c.) Using JDBC requires the explicit-IP of the Oracle server to be defined for each connection. This would require special-handling on the *.rpts at either the source-file (and NOT the CMC level) to change them from DEV -> TEST -> PROD connection. This would result in a lot more Developer / Admin overhead than they are currently used to. [CON]
==================
We would appreciate some advice from anyone who has been down this road before.
What were your Best Practices?
What can you add to the Pros and Cons listed above?
How do we find the "sweet spot" between quality/performance/speed of reports and easy-overhead for the Admins and Developers?
As always, thanks in advance for your comments.

Hi,
I just saw this article and I would like to add some infos.
First you can quite easely reproduce the same way of working with the odbc entries by playing with the oracle name resolution on the server. By changing some files (sqlnet, tnsnames.ora,..) you can define a different oracle server for a specific name that will be the same accross all environments.
Database name will be resolved differently regarding to the environment and therefore will access a different database.
Second option is the possibility to change the connection in .rpt files by an automated way like the schedule manager. This tool is a additional web application to deploy that can change the connection settings of rpt reports on thousands of reports in a few clicks. you can find it here :
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/80af7965-8bdf-2b10-fa94-bb21833f3db8
The last option is to do it with a small sdk script, for this purpose, a few lines of codes can change all the reports in a row.
After some implementations on linux to oracle database I would prefer also the native connection. ODBC and JDBC are deprecated ways to connect to database. You can use DATADIRECT connectors that are quite good but for volumes you will see the difference.

How do I set miminum # of connections for pool with Oracle and Tomcat?

Hi,
I can't seem to find any attribute to initialize the number of connections for my connection pool. Here is my current context.xml file under my /App1 directory:
<Context path="/App1" docBase="App1"
debug="5" reloadable="true" crossContext="true">
<Resource name="App1ConnectionPool" auth="Container"
type="oracle.jdbc.pool.OracleDataSource"
driverClassName="oracle.jdbc.driver.OracleDriver"
factory="oracle.jdbc.pool.OracleDataSourceFactory"
url="jdbc:oracle:thin:@127.0.0.1:1521:oddjob"
user="app1" password="app1" />
</Context>
I've been googling and reading forums, but haven't found a way to establish the minimum number of connections. I've tried all sorts of parameters like InitialLimit, MinLimit, MinActive, etc, with no success.
Here is some sample code that I am testing:
package web;
import oracle.jdbc.pool.OracleDataSource;
import oracle.jdbc.OracleConnection;
import javax.naming.*;
import java.sql.SQLException;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Properties;
public class ConnectionPool {
String message = "Not Connected";
public void init() {
OracleConnection conn = null;
ResultSet rst = null;
Statement stmt = null;
try {
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
OracleDataSource ds = (OracleDataSource) envContext.lookup("App1ConnectionPool");
message = "Here.";
     String user = ds.getUser();
if (envContext == null)
throw new Exception("Error: No Context");
if (ds == null)
throw new Exception("Error: No DataSource");
if (ds != null) {
message = "Trying to connect...";
conn = (OracleConnection) ds.getConnection();
Properties prop = new Properties();
prop.put("PROXY_USER_NAME", "adavey/xxx");
if (conn != null) {
message = "Got Connection " + conn.toString() + ", ";
          conn.openProxySession(OracleConnection.PROXYTYPE_USER_NAME,prop);
stmt = conn.createStatement();
rst = stmt.executeQuery("SELECT username, server from v$session where username is not null");
while (rst.next()) {
message = "DS User: " + user + "; DB User: " + rst.getString(1) + "; Server: " + rst.getString(2);
rst.close();
rst = null;
stmt.close();
stmt = null;
conn.close(); // Return to connection pool
conn = null; // Make sure we don't close it twice
} catch (Exception e) {
e.printStackTrace();
} finally {
// Always make sure result sets and statements are closed,
// and the connection is returned to the pool
if (rst != null) {
try {
rst.close();
} catch (SQLException e) {
rst = null;
if (stmt != null) {
try {
stmt.close();
} catch (SQLException e) {
stmt = null;
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
conn = null;
public String getMessage() {
return message;
I'm using a utility to repeatedly call a JSP page that uses this class and displays the message variable. This utility allows me to specify the number of concurrent web requests and an overall number of requests to try. While that is running, I look at V$SESSION in Oracle and occassionaly, I will see a brief entry for app1 or adavey depending on the timing of my query and how far along the code has processed in this example. So it seems that I am only using one connection at a time and not a true connection pool.
Is it possible that I need to use the oci driver instead of the thin driver? I've looked at the javadoc for oci and the OCIConnectionPool has a setPoolConfig method to set initial, min and max connections. However, it appears that this can only be set via Java code and not as a parameter in my context.xml resource file. If I have to set it each time I get a database connection, it seems like it sort of defeats the purpose of having Tomcat maintain the connection pool for me and that I need to implement my own connection pool. I'm a newbie to this technology so I really don't want to go this route.
Any advice on setting up a proper connection pool that works with Tomcat and Oracle proxy sessions would be greatly appreciated.
Thanks,
Alan

Well I did some more experiments and I am able to at least create a connection pool within my example code:
package web;
import oracle.jdbc.pool.OracleDataSource;
import oracle.jdbc.OracleConnection;
import javax.naming.*;
import java.sql.SQLException;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Properties;
public class ConnectionPool {
String message = "Not Connected";
public void init() {
OracleConnection conn = null;
ResultSet rst = null;
Statement stmt = null;
try {
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
OracleDataSource ds = (OracleDataSource) envContext.lookup("App1ConnectionPool");
message = "Here.";
     String user = ds.getUser();
if (envContext == null)
throw new Exception("Error: No Context");
if (ds == null)
throw new Exception("Error: No DataSource");
if (ds != null) {
message = "Trying to connect...";
boolean cache_enabled = ds.getConnectionCachingEnabled();
if (!cache_enabled){
ds.setConnectionCachingEnabled(true);
Properties cacheProps = new Properties();
cacheProps.put("InitialLimit","5");
     cacheProps.put("MinLimit","5");
cacheProps.put("MaxLimit","10");
ds.setConnectionCacheProperties(cacheProps);
          conn = (OracleConnection) ds.getConnection();
Properties prop = new Properties();
prop.put("PROXY_USER_NAME", "adavey/xyz");
if (conn != null) {
message = "Got Connection " + conn.toString() + ", ";
          conn.openProxySession(OracleConnection.PROXYTYPE_USER_NAME,prop);
stmt = conn.createStatement();
//rst = stmt.executeQuery("SELECT 'Success obtaining connection' FROM DUAL");
rst = stmt.executeQuery("SELECT user, SYS_CONTEXT ('USERENV', 'SESSION_USER') from dual");
while (rst.next()) {
message = "DS User: " + user + "; DB User: " + rst.getString(1) + "; sys_context: " + rst.getString(2);
message += "; Was cache enabled?: " + cache_enabled;
rst.close();
rst = null;
stmt.close();
stmt = null;
conn.close(OracleConnection.PROXY_SESSION); // Return to connection pool
conn = null; // Make sure we don't close it twice
} catch (Exception e) {
e.printStackTrace();
} finally {
// Always make sure result sets and statements are closed,
// and the connection is returned to the pool
if (rst != null) {
try {
rst.close();
} catch (SQLException e) {
rst = null;
if (stmt != null) {
try {
stmt.close();
} catch (SQLException e) {
stmt = null;
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
conn = null;
public String getMessage() {
return message;
In my context.xml file, I tried to specify the same Connection Cache Properties as attributes, but no luck:
<Context path="/App1" docBase="App1"
debug="5" reloadable="true" crossContext="true">
<Resource name="App1ConnectionPool" auth="Container"
type="oracle.jdbc.pool.OracleDataSource"
driverClassName="oracle.jdbc.OracleDriver"
factory="oracle.jdbc.pool.OracleDataSourceFactory"
url="jdbc:oracle:thin:@127.0.0.1:1521:oddjob"
user="app1" password="app1"
ConnectionCachingEnabled="1" MinLimit="5" MaxLimit="20"/>
</Context>
These attributes seemed to have no effect:
ConnectionCachingEnabled="1" ; also tried "true"
MinLimit="5"
MaxLimit="20"
So basically if I could find some way to get these attributes set within the context.xml file instead of my code, I would be a happy developer :-)
Oh well, it's almost Miller time here on the east coast. Maybe a few beers will help me find the solution I'm looking for.

Unable to get a connection for pool - ResourceUnavailableException

Hi
I have a BPEL process which starts a child instance of another asynchronous BPEL process for each message in an XML file. The child BPEL process makes a call to the Oracle Apps JCA Adapter to push the data into E-Business Suite.
All works perfectly except when the number of messages exceeds a certain limit (15 or so). The error received is as follows:
"Exception occured when binding was invoked.
Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'SyncPersonRecord' failed due to:
JCA Binding Component connection issue. JCA Binding Component is unable to create an outbound JCA (CCI) connection.
ebsPeoplesoftEmployees:SyncPersonRecord [ SyncPersonRecord_ptt::SyncPersonRecord(InputParameters,OutputParameters) ] :
The JCA Binding Component was unable to establish an outbound JCA CCI connection due to the following issue:
javax.resource.spi.ApplicationServerInternalException:
Unable to get a connection for pool = 'eis/Apps/Apps',
weblogic.common.resourcepool.ResourceUnavailableException:
No resources currently available in pool eis/Apps/Apps to allocate to applications.
Either specify a time period to wait for resources to become available, or increase the size of the pool and retry.. Please make sure that the JCA connection factory and any dependent connection factories have been configured with a sufficient limit for max connections.
Please also make sure that the physical connection to the backend EIS is available and the backend itself is accepting connections. ".
The invoked JCA adapter raised a resource exception.
Please examine the above error message carefully to determine a resolution."
Obviously what is happening is the connection pool maximum is reached (currently 15) and this is throwing the error.
What I need to do is to implement the suggestion of "specifying a time period to wait" and I was hoping someone could tell me how I do this?
I have tried setting the 'Connection Creation Retry Frequency' parameter to 30 seconds which made no difference and also have checked the documentation on "Configuring and Managing JDBC Data Sources for Oracle WebLogic Server".
Does anyone know if this is something that is implemented directly in the BPEL process/composite or in the connection source itself.
Many thanks

Open the jndi : eis/Apps/Apps in /console - config tab - increase the initial and max conn capacity and save it. Retry the scenario

Informatica's connect for SAP R/3

Hi guru's
I want to know what is informatica's connect for SAP R/3 ? I am an informatica developer and could not find any help regarding this in informatica's documentation.
thanks
your help is greatly apperciated.
preeti

Hi,
Informatica has various ETL capabilities.
It can interact with pretty much all databases.
but to interact with SAP .. informatica has 2 special products
Powerconnect for SAP BW.
Powerconnect for SAP R/3.
These enable you to load/ extract data from SAP and also call API's which are exposed by SAP.
A BAPI is like a function module which can be called remotely.
Thanks & Regards

Connection to mySQL via jdbc

I'm currently programming a GUI to access a database. Therefore I executed a query, which worked fine. But when I tried to exit my program with
System.exit(0)my DOS-Prompt crashes without exiting.
Now I tried it with a kind of minimalistic Connection like that:
Class.forName("org.gjt.mm.mysql.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/stock");
conn.close();Here the same problem occurs, so it must be the Connection that causes the error.
If I would exit the program right away after the Connection, that is
Class.forName("org.gjt.mm.mysql.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/stock");
conn.close();
System.exit(0);then the program exits properly. Unfortunately it doesn't make any sense to quit the program right after reading the data.
So, as you can guess, I'm quite confused. I used the same driver and the same database in another program on the same computer, and it works fine. So I'm left totally clueless.
I'm not using a special programming environment, I just write my code using UltraEdit. I've got installed Java 1.4.0 on my machine.
Any help is very appreciated

I don't get any.
It just crashes. There's neither an exception thrown nor any other error msg.

Exception "not implemented for class oracle.jdbc.driver.T4CNumberAccessor"

Hello I'm having some troubles dealing with 'java.sql.Date' I'm working with express edition database and I have three classes(different packages)
1.Mapper
2.Objects Class
3.ConsoleTest
I need to get an arraylist of objects, some of which contain dates, but when try to do it I get this exception
"java.sql.SQLException: Invalid column type: getDate not implemented for class oracle.jdbc.driver.T4CNumberAccessor"
Do you have any idea how I can implement the getDate method for this T4CNumberAccessor
Here are the methods that I'm using
1.Mapper
public ArrayList<Object> getAllTaskAuctions(Connection con)
          ArrayList<Object> l1 = new ArrayList<Object>();
          String SQLString1 = "select * from taskauction natural join tasks";
PreparedStatement statement=null;
try
//=== get taskauctions natural join tasks
statement = con.prepareStatement(SQLString1);
ResultSet rs = statement.executeQuery();
while(rs.next())
l1.add(new TaskAuction(rs.getInt(1), rs.getInt(2), rs.getInt(3),
rs.getDate(4), rs.getDate(5), rs.getInt(6)));
l1.add(new Task(rs.getInt(1), rs.getInt(2), rs.getString(3),
rs.getString(4), rs.getString(5), rs.getString(6), rs.getInt(7)));
catch (Exception exc)
System.out.println("Fail in TaskAuctionMapper - getAllTaskAuctions");
System.out.println(exc);
return l1;
2.ConsoleTest class
Connection con;
     public Connection getConnection(){
          try{
     Class.forName("oracle.jdbc.driver.OracleDriver");
     con = DriverManager.getConnection(
     "jdbc:oracle:thin:@localhost:1521:XE", "Project", "123" );
     //username/password@[/]host[:port][service_name]
     catch (Exception e)
     {   System.out.println("fail in getConnection()");
     System.out.println(e); }
          return con;
     public static void main(String[] args) {
          ConsoleTest ct = new ConsoleTest();
          TaskAuctionMapper tam1 = new TaskAuctionMapper();
ArrayList<Object> alt1 = tam1.getAllTaskAuctions(ct.getConnection());
Iterator<Object> itr1 = alt1.iterator();
while (itr1.hasNext())
TaskAuction taskauct = (TaskAuction) itr1.next();
//Problem, exception traced to TaskAuctionMapper
System.out.println(
          "Task ID: " + taskauct.getTaskid()+ ", "+
          "StartDate: "+ taskauct.getStartdate()+", "+
          "User ID: " + taskauct.getUserid());
     }

Found the answer, I shouldn't use integers as parameters of column index in the result set, but instead use String to mark the fields :)

Using Ant task wlserver/wlconfig: Received exception while creating connection for pool.

Hi,
I am using ant tasks wlserver and wlconfig to configure my weblogic server. while creating a connection pool as shown below
<target name="jdbcinfo">
<wlconfig password="weblogic"
username="weblogic"
url="${url}"
<query domain="mydomain" type="Server"
name="myserver" property="serverbean"
/>
<create type="JDBCConnectionPool"
name="jdbcpoolA"
property="jdbcPoolProp">
<set value="false"
attribute="ShrinkingEnabled"
<set value
attribute="
<set value="${serverbean}"
attribute="Targets"/>
The JDBCConnectionPool is created as long as I don't specified the attribute "Targets"
Once I add the target I get the following error
<JDBC> <BEA-001129> <Received exception while creating connection for pool "poolname" invalid arguments in call>
Please any help will be greatly appreciated.
Thanks

In your applicaion module configurations check if you are using 'JDBC URL' or 'JDBC DataSource'. You should use JDBC DataSource. Then make sure that your deployment descriptor (menu 'Application->Application Properties->Deployment) has the 'Auto Generate ...' checkbox set.

Connection issues with Oracle-JDBC

Using the Universe Design Tool in BOE 4.4 to create an Oracle-JDBC connection.
Issue: Test Connection fails for JDBC connection to production Oracle database.
Getting error:
“DBD: ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
IBM AIX RISC System/6000 Error: 2: No such file or directory”
Things to note:
There are three entries in the tnsnames.ora file (a prod entry, a dev entry and a test entry). I can successfully create the JDBC connections for the test and dev entries, but not prod.
I can go to Designer in another server (our BOE 3.5 server in a different environment) and create all three Oracle-JDBC connections.
The Oracle middleware is the same between the two servers (11g) and the tnsnames.ora files are identical.
The prod database is up (it would definitely be known if it were down).
Very confused on this one. Any help would be appreciated.

It appears that the SAP tool “Universe Design Tool” wants to have a fully qualified (host.parent domain.org) Net Service name for this particular connection as I was able to successfully JDBC connect to our production Oracle database. The other two databases didn't need it and the Oracle SQL Developer (which uses JDBC for connections) didn’t need a fully qualified name for our production server either. In any case, it appears to be working now.

[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'.
