Error in connections with jdbc connection pool

[Anna Bikkina]

Hi,

I am using jdbc collection pool in cocoon.xconf to connect to my 
database from my cocoon portal server. Sometimes the dba does some 
audits and kills some connections in the database. In the application 
when I am trying to connect I want to make sure that the connection is 
alive before using it . I am currently getting a broken pipe and  Socked 
not found exception whenever there is a broken connection. Any help is 
greatly appreciated. Here are the tags I am using.

<jdbc logger="core.datasources.db1" name="db1">
        <pool-controller min="3" max="10" />
        <auto-commit>false</auto-commit>
        
<dburl>jdbc:informix-sqli://xxx:1532/xxxdb:INFORMIXSERVER=xx1db</dburl>   
        <user>informix</user>
        <password>informix</password>
        <driver>com.informix.jdbc.IfxDriver</driver>
   </jdbc>

I am using esql to connect to the database.. here is how I am using them.
esql:connection>
                 <esql:pool>db1</esql:pool>
                 <esql:execute-query>
                     <esql:query>SET LOCK MODE TO WAIT ;</esql:query>
                 </esql:execute-query>
                 <esql:execute-query>
                     <esql:query>SET ISOLATION TO DIRTY READ;</esql:query>
                 </esql:execute-query>
                   <esql:execute-query>
                     <esql:call  needs-query="true">{call 
xxx_proc()}</esql:call>
                       <esql:results>
                        <esql:row-results>.......

Thanks,
Anna.
