Thanks Mark.
Can you confirm that I can have one data source "shared" across all contexts
with the following configurations:
In CATALINA_BASE/conf/server.xml, I define a GlobalNamingResource as
follows:
<GlobalNamingResources>
...
...
Resource name=*"@tomcat.context.ece.read.ds.resource@"* auth=*"Container"
type="@tomcat.context.driver.type@" driverClassName=
"@tomcat.context.driver.class@" url="@tomcat.context.db.url@"
connectionProperties=
"{validateconnecti...@tomcat.context.validate.connection@
,connectionwaittimeo...@tomcat.context.connection.wait.timeout@}" username=
"@tomcat.context.db.user@" password="@tomcat.context.db.password@"
validationQuery="@tomcat.context.validation.query@" initialSize=
"@tomcat.context.initial.size@" minIdle="@tomcat.context.min.idle@"
maxActive="@tomcat.context.max.active@"maxIdle="@tomcat.context.max.idle@"
maxWait="@tomcat.context.max.wait@"removeAbandonedTimeout="60"
removeAbandoned="true" logAbandoned="true"/>*
</GlobalNamingResources>
I then reference it in CATALINA_BASE/conf/context.xml as follows:
<Context>
<ResourceLink name="@tomcat.context.ece.read.ds.resource@"
global="@tomcat.context.ece.read.ds.resource@"
type="@tomcat.context.driver.type@"/>
</Context>
