[opencms-dev] Monitoring Oracle 11g database access

[Jose Ignacio Yarza]

Hi List,

 

Environment: OpenCMS 8.5, Oracle 11g

 

We want to monitor database access within a custom JSP that uses the OpenCMS
taglib/API. What we need is to generate an Oracle trace file with all the
SQL instructions that happen within that particular JSP, regardless if they
belong to different database connections within a pool.

 

The issue is that we don't get any info in the trace file about the OpenCMS
queries. We are trying this:

 

<%

String CLIENT_ID = String.valueOf(new Date().getTime());

Connection dbConnection = OpenCms.getSqlManager().getConnection("default");


CallableStatement cstmt1 = dbConnection.prepareCall("{call
dbms_session.set_identifier(?)}");

cstmt1.setString(1, CLIENT_ID);

cstmt1.executeUpdate();

 

CallableStatement cstmt2 = dbConnection.prepareCall("{call
dbms_monitor.client_id_trace_enable(?)}");

cstmt2.setString(1, CLIENT_ID);               

cstmt2.executeUpdate();           

 

CmsJspActionElement cjae = new CmsJspActionElement(pageContext, request,
response);                                                  

CmsObject cms = cjae.getCmsObject();

CmsRequestContext crc = cms.getRequestContext();

 

(.) // some JSP code accesing contents

 

CallableStatement cstmt3 = dbConnection.prepareCall("{call
dbms_monitor.client_id_trace_disable(?)}");

cstmt3.setString(1, CLIENT_ID);

cstmt3.executeUpdate();

 

(.) closing stuff

%>

 

 

All we get in the Oracle trace file are the explicit procedure calls. I am
not very familiar with this Oracle technique. Anyone has tried this? Why are
we not getting any trace from the api internal queries? Might be because
they are happening in another connection or session or something else?

 

Any comment is welcome. Thanks.
