Hi,
When
you configure DODS to use “DataSourceConnectionAllocator” and
“DataSourceDBConnectionFactory” you are practically telling DODS to try to use
external “javax.sql.DataSource” implementation!
This
DataSource instance should be provided by Enhydra (Tomcat) server and referenced
trough replacement parameter (“DataSourceName”).
In
your case (sample configuration):
<env-entry>
<env-entry-name>DatabaseManager/DB/i10/Connection/DataSourceName</env-entry-name>
<env-entry-value>jndi:i10</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>
Standard
mechanism for some application resource initialization and configuration is
trough context descriptor files (<app_context>/META-INF/context.xml) and
corresponding <Resource/> definitions.
Please,
consult Tomcat documentation for additional details about this topic
(http://tomcat.apache.org/tomcat-5.5-doc/jndi-resources-howto.html)!
I’ve
prepared sample context descriptor for you and did (DataSource related)
configuration changes in your DatabaseManager configuration
(attached).
Also,
please use the enhydra mailing list whenever you can (not my personal
email)!
I’m
sure that others mid experience the same “problems” during their migration to
the latest TAS (Enhydra) release.
Please,
don’t hesitate to ask for any further help!
Regards,
Slobodan

Hi
Slobodan
Thanks
for your answer.
I have
already deployed Lambda Probe. It is a really interesting tool. However, I can't
see information about data sources, When I click on "Data Sources", the tool
presents an error message "There no data sources configured for this Tomcat
instance". The connection allocator of my webapp is
"com.lutris.appserver.server.sql.datasource.DataSourceConnectionAllocator".
In
attachment, I send you my database configuration.
Can you
help me ? Thanks.
Best
regards
Luis Oliveira

Hi
Luis,
For
basic application management functions (start, stop, reload, undeploy, deploy
and delete) you can use either “EnhydraManager” or “manager” (Tomcat Manager)
application.
I’m
more used to “EnhydraManager”! It has slightly bigger feature list and supports
multi-service/host configurations.
Regarding
monitoring tool, you can find number of Tomcat monitoring tools on the internet
(some of them will allow you to monitor your DB
connections).
I’m
using “Lambda Probe” (formerly known as Tomcat Probe - GPL license) - http://www.lambdaprobe.org
Regards,
Slobodan

Subject: [enhydra] Multiserver
Admin Console in TAS7
Hi
I used to develop applications to Enhydra
3.x and manage it using Multiserver Administration Console. Now these
applications are running in TAS (Together Application Server) and I
would like to know if there’s a similar application on TAS7 or Enhydra 6.x.
How can you stop and start a webapp on TAS7?
Is it necessary to shutdown the TomCat to stop only one application or is it
possible to stop and start each webapp independently? Besides, how can
you known the number of connections to database that each webapp have
allocated?
Thanks.
Best Regards
Luis Oliveira
