Hi Chris,
Thanks a lot for your help!!Much appreciated!!
We could able to locate context.xml under " /apps/apache-tomcat-7.0.67/conf"
path - see below:
<!-- Default set of monitored resources -->
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<!-- Uncomment this to disable session persistence across Tomcat restarts
-->
<!--
<Manager pathname="" />
-->
<!-- Uncomment this to enable Comet connection tacking (provides events
on session expiration as well as webapp lifecycle) -->
<!--
<Valve className="org.apache.catalina.valves.CometConnectionManagerValve" />
-->
<Resource name="jdbc/E2EMFPostGres" auth="Container"
type="javax.sql.DataSource"
maxActive="50" maxIdle="30" maxWait="10000"
username="saevdcep" password="xxxxxx"
driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://itsusralsp06829:5432/spectra"/>
<Resource name="jdbc/EVDSEARCH" auth="Container" type="javax.sql.DataSource"
maxActive="50" maxIdle="30" maxWait="10000"
username="saevdcep" password="xxxxxxx"
driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://itsusralsp06829:5432/evidencesearch"/>
</Context>
Could you please check which are the parameters to add/modify/delete.
Also we could locate another "context.xml" under "
/apps/apache-tomcat-7.0.67/webapps/host-manager/META-INF" and "
/apps/apache-tomcat-7.0.67/webapps/manager/META-INF" path - could you please
advise if we need to make any change here:
<Context antiResourceLocking="false" privileged="true" >
<!--
Remove the comment markers from around the Valve below to limit access to
the host-manager application to clients connecting from localhost
-->
<!--
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
Thanks and Regards,

I think you might need another member of your team to advise you on this
subject and maybe represent you within this community.
The file in question is part of Tomcat's user manual. It is not a configuration
file, and is not a part of your own application.

The real configuration is usually in a file called context.xml in your
application's META-INF directory.
