To clean your intelligent agent on Oracle 9i, do the following steps:

1.        Make sure to remove all jobs and events registered against your server using OEM.

2.        Make sure your agent is shutdown. #agentctl stop

3.        Relink the agent. # $ORACLE_HOME/network/lib/make –f ins_oemagent.mk install 1>log.1 2>log.2

4.        Login to root and change the ownership and mode of the $ORACLE_HOME/bin/dbsnmp file.

a.       # su root

b.       # chown root $ORACLE_HOME/bin/dbsnmp

c.       # chmod 6751 $ORACLE_HOME/bin/dbsnmp

5.        Now, clean the agent:

a.       Go to the $ORACLE_HOME/network/agent directory and delete the following files:

                                                               i.      # {services.ora, *.q, *.inp, *.jou, and out*}

                                                             ii.      NOTE: DO NOT DELETE the SVPPCART.DAT file that exists with 9.0.1 and later Agents. This file is the definition file for the Agents Data Gatherer Cartridge and is not generated by the Agent.

b.       Go to the $ORACLE_HOME/network/admin directory and delete the following files:

                                                               i.      # {snmp_ro.ora, snmp_rw.ora

c.       Rename all the log files in the $ORACLE_HOME/network/log directory.

d.       Make sure that you don’t have any core dumps in the ORACLE_HOME/network/lib directory.

e.       Recreate the snmp_ro.ora file with the following line. (snmp.visibleservices = ())

6.        Start the agent (# agentctl start).  If the above didn’t work then activate the trace on the agent by the following statements and read the snmp.log file.

c.        dbsnmp.trace_level =16

d.        dbsnmp.trace_unique=true

SERVICES.ORA

This file contains all the services the agent has discovered. This file will be recreated the next time the agent starts.

*.q

These files are the binary representation of all registered and running jobs and events. The agent creates new fresh files on startup when they do not exist. Information about the host the agent is running on is stored in these files. If the name or the IP address of the agent machine changes, these files need to be recreated.

*.inp

These files are parameter files for registered jobs.

*.jou

These files are journal files with information the agent will use to execute jobs.

out*

These files are temporary output files. These files are generated when jobs are being executed and should be automatically removed by the agent after a job finishes.

tcl*

These files are TCL template scripts, including the specific commands specified in the job send to the agent. There are

*.tcl files in other directories � DO NOT delete the other TCL files. They are scripts that ship with the Agent.

DBSNMP.VER

This file is a text file with the agent version information. This file will also be recreated when the agent starts again.

SNMP_RO.ORA

This file contains read-only information about the Agents discovered services on the machine. This file should never be manually edited! During startup, this file is read if it exists, and then recreated again with the new discovery information.

SNMP_RW.ORA

This file contains read-write information about the Agents discovered services on the machine. Some of the information in this file can be edited by an administrator to provide additional information like tracing / logging and hostname resolution, etc. During startup, this file is also read if it exists and new discovery information is appended to the file.
