Re: Help: Connecting Tomcat to CA-IDMS using JDBC Type 4 Drivers (JNDI / IDMSDataSource)
I have some more questions: For my datasource connection paramaters I have the IdmsDataSource class, and the IdmsConnectionPoolDataSource class. The IdmsDataSource class is used with an application server provided Java Naming and Directory Interface (JNDI) naming service to establish a connection to a CA IDMS database. IdmsDataSource properties are used to specify the connection parameters. These properties are the equivalent of the DriverPropertyInfo attributes described in the previous section and can be used to completely define the parameters needed to connect to a database. Here are some IdmsDataSource properties: accountInfo, connectSuspend, databaseName, dataSourceName, externalWait, networkProtocol, password, portNumber, programName, resourceInterval, roleName, serverLength, serverName, serverTrace, user etc etc. Can these simply be placed in the server.xml config under my resource as follows: Resource name=jdbc/TestIDMS auth=Container type=javax.sql.DataSource maxActive=100 maxIdle=30 maxWait=1000 connectSuspend=true dataSourceName=something externalWait=20 networkProtocol=TCP username=test password=test driverClassName=ca.idms.jdbc.IdmsJdbcDriver url=jdbc:idms://IP:3709/DICT removeAbandoned=true removeAbandonedTimeout=300 logAbandoned=true / I went ahead and set these, and upon shutdown and restart Tomcat does not give any error. However, the instructions say to use the caidms.properties file (where these properties should be set) and include the location to the file in the $CLASSPATH. I'm wondering if I can use either of these methods? The IdmsConnectionPoolDataSource class implements the JDBC ConnectionPoolDataSource interface. It is used with an application server that provides container managed connection pooling to establish a pooled connection to a CA IDMS database. IdmsConnectionPoolProperties are used by the application server connection pool manager to administer the pool of connections for a particular data source. Does Tomcat support this method? Some properties for this class are: connectSuspend, initialPoolSize, maxIdleTime, maxPoolSize, propertyCycle etc. Can these properties also be added to the resource in the server.xml config (if Tomcat supports this method)? Any help would be great. rgds J -- View this message in context: http://www.nabble.com/Help%3A-Connecting-Tomcat-to-CA-IDMS-using-JDBC-Type-4-Drivers-%28JNDI---IDMSDataSource%29-tp21433283p21478261.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Help: Connecting Tomcat to CA-IDMS using JDBC Type 4 Drivers (JNDI / IDMSDataSource)
Filip, here is my configuration so far:
I have created a test application under the tomcat webapps folder with the
following structure:
IDMSTest/
IDMSTest/WEB-INF/
IDMSTest/WEB-INF/classes/
IDMSTest/WEB-INF/lib/
IDMSTest/WEB-INF/web.xml
IDMSTest/WEB-INF/test.jsp
Here is my IDMSTest/WEB-INF/web.xml file:
?xml version=1.0 encoding=UTF-8?
web-app xmlns=http://java.sun.com/xml/ns/j2ee;
xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;
xsi:schemaLocation=http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd;
version=2.4
descriptionIDMS Test App/description

descriptionDB Connection/description
res-ref-namejdbc/TestIDMS/res-ref-name
res-typejavax.sql.DataSource/res-type
res-authContainer/res-auth
/resource-ref
/web-app
I also added the following to tomcat/conf/server.xml:
!-- Tomcat JDBC to IDMS Test Context --
Context path=/IDMSTest docBase=IDMSTest reloadable=true
crossContext=true
Resource name=jdbc/TestIDMS auth=Container
type=javax.sql.DataSource
maxActive=100 maxIdle=30 maxWait=1
username=MY_USER password=MY_PASS
driverClassName=ca.idms.jdbc.IdmsJdbcDriver
url=jdbc:idms://MY.IP.ADDRESS:MY.PORT/MY_DATABASE /
/Context
Then I have a test.jsp in the IDMSTest/ folder with the following code:
%@ taglib uri=http://java.sun.com/jsp/jstl/sql; prefix=sql %
%@ taglib uri=http://java.sun.com/jsp/jstl/core; prefix=c %
sql:query var=rs dataSource=jdbc/testIDMS
select text_message from messages
/sql:query
html
head
titleIDMS DB Test/title
/head
body
h2Results/h2
c:forEach var=i items=${rs.rows}
Text Message: c:out value=${i.text_message}/br
/c:forEach
/body
/html
However, I can't actually test anything yet, as the IDMS is not setup to
listen to JDBC requests. I just wanted to be clear that my configuration and
syntax on the Linux / Tomcat side are correct for when I do come to test a
connection. The SQL query and query handling code in the JSP file would
differ depending upon the database structure, obviously.but does
everything look like its setup OK? Where would the
javax.naming.spi.ObjectFactory implementation come into it?
There are some remaining issues I have about how to setup and use the
caidms.properties file and the caidms.cfg file. I've uploaded the 2 files as
they contain quite a lot of code:
http://www.nabble.com/file/p21451684/caidms.cfg caidms.cfg
http://www.nabble.com/file/p21451684/caidms.properties caidms.properties

If your JDBC driver has a DataSource, then check to see if it has a
javax.naming.spi.ObjectFactory implementation, this is the one you would
specify in the factory=some.impl.DataSourceFactory attribute, for
example.
Some drivers don't have factories, and then you simply use Tomcat's own
factory by omitting the factory attribute.
In this case, Tomcat will provide the DataSource that is a wrapper
around your driver.
Provide
1. the configuration (only relevant parts)
2. the error you get

Hi there,

We have a zSeries 9 IBM mainframe running CA-IDMS r16.1, and I need to

At this stage I am struggling with the actual setup and configuration of
Tomcat’s server.xml and web.xml files. These are the files where the JDBC

I set up a Tomcat to MySQL connection using MySQL Connector / J, which is
a
similar kind of process to what I am trying to achieve with IDMS. MySQL
connector / J came with a jar file which is placed in Tomcat’s lib
folder,
and then the JDBC setup for the web application is created in Tomcat's
server.xml and web.xml files. You can then connect to the MySQL database
using JSP and the configured JDBC driver / connection. The CA-IDMS Server
comes with an idmsjdbc.jar file, which I think is the JDBC typr 4 driver.
I
think it needs to be placed in the Tomcat /lib folder, but I don’t know
how
to set up the configuration.
There is a JDBC DriverManager which allows JDBC drivers to connect to
CA-IDMS. The DriverManager recognises the following syntax:
jdbc:idms://hostname:port/database
This allows the JDBC driver running within Tomcat to connect to the IDMS
which is running on the IDM mainframe. CA IDMS r16 supports direct
connections from the Type 4 JDBC driver to the Central Version on IDMS.
hostname is the DNS name or IP address of the machine where the CV is
running, and port

Yeah thanks Filip, I read online about that being the problem.
I think I am now ready to setup the IDMS so that it will listen to JDBC
calls. Once I have this all setup I will come back to let you know how I got
on.
Thanks for all the help everyone.

Help: Connecting Tomcat to CA-IDMS using JDBC Type 4 Drivers (JNDI / IDMSDataSource)
Hi there, I have a rather interesting / complex problem..creating a connection to CA-IDMS from Tomcat using JDBC type 4 drivers (CA provide the type 4 driver).

There is a caidms.properties file for the JDBC driver, which is used to specify user ID, password, and optional accounting information. It can also be used to specify physical connection information, allowing an application to connect to a CA-IDMS database without requiring the definition of an ODBC style data source. However, I don’t know where to place this file within the Tomcat setup. There is also an IdmsDataSource class. I don’t know where to configure this or how to set it up; the CA-IDMS Server manual states the following: This class implements the JDBC DataSource interface. It is used with an application server (Tomcat) providing Java Naming and Directory Interface (JNDI) naming service to establish a connection to a CA IDMS database. IdmsDataSource properties conform to the Java Beans naming conventions and are implicitly defined by public “setter” and “getter” methods. For example, the “description” property, which is required for all DataSource implementations, is set using the setDescription(String) method. The application server may use the java.lang.reflection methods to discover DataSource properties and provide an interface to set them, or may simply require that they are defined in some configuration file. IdmsDataSource properties are used to specify the connection parameters. These properties are the equivalent of the DriverPropertyInfo attributes described in the previous section and can be used to completely define the parameters needed to connect to a database. Like a URL, an IdmsDataSource object can also reference an “ODBC” style data source name, where the connection parameters are defined in the configuration file on Linux. Is there anyone that can try to point me in the right direction to setting up the JDBC connection? I am totally new to Java and so the instructions are not making much sense at the moment. Any help, hints, tips…..anything will be greatly appreciated as I have just hit a brick wall here. I can't find much to do with setting up the CA-IDMS Server JDBC type 4 driver online eitherif anyone can point me to some resources that would also be extremely useful.
