When I am trying to connect to DB2 using schema definition in connection url it works fine
spring.datasource.url=jdbc:db2:/server:xxxx/ins:currentSchema=DEVSCHEMA;
but when the same is tried from tomcat jndi using
<Resource
auth="Container"
defaultAutoCommit="false"
driverClassName="com.ibm.db2.jcc.DB2Driver"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
initialSize="10"
maxActive="100"
maxIdle="80"
minEvictableIdleTimeMillis="55000"
minIdle="30"
name="jdbc/connDB"
password="xxxxxxx"
removeAbandoned="true"
removeAbandonedTimeout="55"
testOnBorrow="true"
timeBetweenEvictionRunsMillis="34000"
type="javax.sql.DataSource"
url="jdbc:db2:/server:xxxx/ins:currentSchema=DEVSCHEMA;"
username="xxxxx"
validationInterval="34000"
validationQuery="select 1 from sysibm.sysdummy1"/>
I get error
DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=DEVSCHEMA.tablename, DRIVER=4.31.10
The jar used in the classpath is jcc-11.5.7.0.jar, ojdbc6-11.2.0.4.jar, for both instances.
Using springboot version 2.7.4
Is there any configuration that needs to be added to fix the issue.

I'm trying to use a Spring app with Tomcat context jdbc
The validation query is executed, but when I tried to execute in the Java Code:
st.executeQuery(sqlQuer) returns "Object 'XX' does not exist or not authorized.
In the web client the query works with the same login credentials.
Anybody done this? If so can you share what you did?
I'm using:
<Resource name="jdbc/snowflake" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.snowflake.SnowflakeDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:snowflake://snowflakecomputing.com/?Database=MyDb;Warehouse=TestWarehouse;"
username="myuser"
password="12234"
maxActive="20" maxIdle="10" maxWait="-1" validationQuery= "select 1 from dual/>
I have upgraded Tomcat from 7 to 9. I am getting exception while start up. It is throwing below exception:
oracle.jdbc.xa.client.OracleXADataSource cannot be cast to java.sql.Driver
context.xml has following :
<Resource auth="Container" driverClassName="oracle.jdbc.xa.client.OracleXADataSource"
logAbandoned="true" initialSize="1" maxActive="2" maxIdle="2"
minIdle="2" timeBetweenEvictionRunsMillis="34000"
inEvictableIdleTimeMillis="55000" validationQuery="SELECT 1 FROM DUAL"
validationInterval="34" testOnBorrow="true" removeAbandoned="true"
removeAbandonedTimeout="600" name="jdbc/regionalDS" password="XXX"
type="javax.sql.DataSource" url="jdbc:oracle:thin:#HOSTURL"
username="XXX" />
Please let me know, what changes I need to do.
Two things you can try :
1. Change the type to type="javax.sql.XADataSource"
2. Check that the url is in the form of url="jdbc:oracle:thin:#your_host_name:port_say_1521:service_or_sid"
I have a web application that uses Tomcat 7, Spring MVC 4.0, and JPA (Hibernate implementation). I am migrating this application to jBoss/Wildfly application server.
Currently, the DataSource is injected in the application with JNDI in a Spring configuration file:
<jee:jndi-lookup id="dataSource" jndi-name="jdbc/MY_DB" expected-type="javax.sql.DataSource" />
The data source itself is defined in $CATALINA_HOME/conf/context.xml in the following way:
<Context>
<Resource name="jdbc/MY_DB"
auth="Container"
type="javax.sql.DataSource"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/MY_DB?useUnicode=yes&characterEncoding=UTF-8"
username="user1"
password=""
validationQuery="select 1"
removeAbandoned="true"
removeAbandonedTimeout="120"
maxWait="60"
maxActive="20"
maxIdle="10" />
</Context>
How can I define this JNDI DataSource in JBoss/Wildfly?
First, you must make the JDBC driver available to the application server; then you can configure the data source itself.
See more details in Data Source Configuration in AS 7 and DataSource configuration
I want to set the fixedString=true connection property for the Oracle JDBC driver in the datasource definition in Orion Application Server 2.0.7 (latest stable release).
I've tried the following but didn't work:
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="datasource_name" location="jdbc/datasource_location"
connection-driver="oracle.jdbc.OracleDriver"
username="user" password="pass"
url="jdbc:oracle:thin:#//database_host:1521/XE" >
<property name="fixedString" value="true" />
</data-source>
Note: I've managed to set the property in Tomcat 6.0 this way (using the same Oracle JDBC driver, of course):
<Resource name="jdbc/datasource_name" auth="Container" type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="user" password="pass" driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:#//database_host:1521/XE"
connectionProperties="fixedString=true;"
/>
But I need to set this in Orion. How can I do that?
It is a bug in the oracle application server you have to install OAS 10.1.2.3 has fix for that
My webapp is running on Tomcat 5.5, I declared the datasource in web.xml:
<resource-ref>
<res-ref-name>jdbc/OrdiniWebDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
In context.xml (tomcat conf):
<Resource
auth="Container"
driverClassName="com.mysql.jdbc.Driver"
maxActive="100"
maxIdle="30"
maxWait="10000"
name="jdbc/OrdiniWebDS"
password="[mypassword]"
type="javax.sql.DataSource"
url="jdbc:mysql://[myHost:port]/ordiniweb"
username="[myusername]"
/>
The database is a MySql 5.0.
Everything works well except that sometimes, after several hours of "unuse", at first access I got this Exception:
com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception:

I need to refresh and it works well again. Any idea? Thanks.
MySQL drops unused connections after a while because it assumes that the other side forgot to close it.
What you need to do is to configure a check that Tomcat should apply before it reuses a pooled connection. To do this, add ?autoReconnect=true&useUnicode=true&characterEncoding=utf8 to the end of the URL and add validationQuery="Select 1" to the Resource element:
<Resource
auth="Container"
driverClassName="com.mysql.jdbc.Driver"
maxActive="100"
maxIdle="30"
maxWait="10000"
name="jdbc/OrdiniWebDS"
password="[mypassword]"
type="javax.sql.DataSource"
url="jdbc:mysql://[myHost:port]/ordiniweb?autoReconnect=true&useUnicode=true&characterEncoding=utf8"
username="[myusername]"
validationQuery="Select 1"
/>
