    How can I configure more than one MySQL database?

    Luc Vu Newbie

      Hello everyone!

      I am currently using JBoss 3 + Tomcat 4.03 bundle. I got the MySQL datasource working for one database. How do I setup for more than one MySQL databases?

      Thanks!

            YES PLEASE!!! I have been trying to find the solution for about 3 days now. I'm looking to configure 2 SQL datasources. I'm guessing the same applies ...

            thx in advance

              Let me tell you what I did.

              I am using JBoss-3.0.0_tomcat-4.0.3. In the JBOSS_TOMCAT_INSTALL_DIR/docs/examples/jca there is a template for setting up mysql call "mysql-service.xml". [Don't use the latest version from SourceForge because it it has one line out of place so it doesn't work.] I made 2 copy of mysql-service.xml and name them as follow: mysqlDS1-service.xml and mysqlDS2-service.xml. You can name it them to whatever you want but they must follow with "-service.xml".

              In mysqlDS1-service.xml I modified the following:
              1) rename all MySqlDS to MySqlDS1
              2) modify jdbc:mysql://dell:3306/jbossdb to jdbc:mysql://localhost:3306/database1
              3) add username and password

              In mysqlDS2-service.xml I modified the following:
              1) rename all MySqlDS to MySqlDS2
              2) modify jdbc:mysql://dell:3306/jbossdb to jdbc:mysql://localhost:3306/database2
              3) add username and password

              Put both files in the default/deploy folder.

              Check to see if your datasource is up, goto http://localhost:8082 and click on service=JNDIView. Scroll down to the bottom and click on the list button. Goto the java:Namespace you should see MySqlDS1 and MySqlDS2.

              Notice that I added the username and password and I didn't use the MySqlDbRealm policy. I will try to use the MySqlDbRealm later.

              I hope this help.

                Add another service ... how obvious is that!! Can't believe I never thought of it :)

                All working fine now. Thank you so much Luc!!

                  I'm using JBoss3.0.1 with Jetty. I've followed the instructions to create 2 DS. However, I got the following error messages. Any idea? Thanks.

                      thanks lucvu :

                      that is really good idea, however, how about 3 dbs?

                      I am trying carete 3 dbs connection by your way.but only two of them work OK.:(

                      I am using the exactly same environment as you, the default connection work fine.Moreover,I create msql2-service.xml and mysql3-service.xml for other two connections.

                      I am useing ejb staff to connect db and one reference another. So, I have to build ejb2 and then ejb3, the problem is the ejb3 always connect ejb2's dababase?

                      do you have idea about this? where should I specify database for ejb?
                      jbosscmp-jdbc.xml?
                      I change it!

                      java:/MySQL3

                      <fk-constraint>true</fk-constraint>



                      java:/MySQL2
                      <datasource-mapping>mySQL</datasource-mapping>

                      any ideas?

                        cake -- your config file needs to be named *-service.xml. *-service2.xml will not be recognized.

                        mgao -- only one set of defaults/file, please, the parser can't read your mind. Use 3 ejb jars or specify the datasource per ejb. Consult the jbosscmp-jdbc.dtd to see how to do this.

                          thanks for your reply davidjencks:
                          I have three ejb apps and jar them saparately in one server. I specify three mysql-service.xml. naming mysql, mysql2 and mysql3, each of them end with -service.xml.

                          In each apps, name the jbosscmp-jdbc.xml default section as
                          //-- for mysql-service.xml

                          is that right?

                          what do you mean "one set default/file?"
                          default element in jbosscmp-jdbc.xml?

                            Sorry, I misinterpreted your earlier post. What you show with the 3 files should work AFAIK. If the 3 datasources are getting deployed successfully I would ask in the cmp forum, I'm not such an expert on how this particular xml is interpreted.

                              thanks davidjencks

                              the three databses connection in my computer work fine now, I retry that way and create the 4th connection, it works! it might be my careless for the 3rd one.

                              Anyway, thank you very much indeed!

                              cheers
