"When
one door of happiness closes, another opens; but often we look
so long at the closed door that we do not see the one which
has been opened for us."

How
to start, trace 8i and 9i Data Collection Service
(Data
Gatherer and Intelligent Agent)?
In
9i, the Data Collection Service is integrated in the Intelligent
Agent. You must trace the Intelligent Agent to trace the Data
Collection Service.
In
8i, The Data Collection Service is a separate process, the Data
Gatherer. You must trace the Data Gatherer process.
9i
Data Collection Service on Unix
----------------------------------
1.
Stop the Intelligent Agent if it is started
$>
agentctl stop
2.
Set the environment variable VP_DEBUG to 1
$>
setenv VP_DE<BUG:1> or export VP_DEBUG=1
3.
Start the Intelligent Agent
$>
agentctl start
Data
Collection Service debug information will be logged in the file dbsnmp.
nohup
located in ORACLE_HOME/network/log (by default)
9i
Data Collection Service on Windows
--------------------------------------
1.
Stop the intelligent agent service if it is started
2.
Open a dos command window
3.
Set the environment variable VP_DEBUG
c:\oracle\product\ia\bin>
set VP_DEBUG=1
4.
Start the intelligent agent
c:\oracle\product\ia\bin>
dbsnmp -agent_name <
Intelligent_agent_service_name>
for
example : dbsnmp -agent_name Oracleora92Agent
Data
Collection Service debug information will be logged at screen. To
redirect debug information to file odg.log for example :
dbsnmp
agent_name Oracleora901Agent > stdout.log 2> odg.log
Pre-9i
Data Collection Service on Unix
--------------------------------------
1.
Stop the Data Collection Service (Data Gatherer process) if it is
started
$>
vppcntl -stop (-status or -start)
2.
Start the Data Collection Service with the following command
$>
vppdc -debug > output.log 2> odg.log &
This
will redirect Data Collection Service debug information in the file
odg.log
Pre-9i
Data Collection Service on Windows
-----------------------------------------
1.
Stop the Data Collection Service (Data Gatherer service) if it is
started
2.
Open a dos command window
3.
Start the Data Collection Service with the following command
c:\oracle\product\ia\bin> vppdc -console -debug > stdout.txt
2> odg.log
This
will redirect Data Collection Service debug information in the file
odg.log which is located in ORACLE_HOME\odg\log
