Install the 32-bit Debugging Tools for Windows.
The 32-bit version is the best choice unless you are debugging an application

In this case the first process is a parent process , we are not interested in this , we are more
bothered about the second process.

For the oracle.exe you can use the command ,

pslist -d oracle

2. Now go to the directory
c:\windebug\userdump and run the setup.exe ,

3. This will install the userdump.exe in C:\WINNT\system32
4. Now issue the command ,

userdump 2528 f:\temp1\apache.dmp

5. Now open the windbg tool , from

Start -> Program Files -> Debuuging Tool For Windows -> WinDbg

6. Now choose the option ,

File -> Open Crash Dump

And select the file f:\temp1\apache.dmp

6. After this select the menu option ,
View -> Call Stack and

How the DCM and OPMN gets the database users and passwords from OID

The RepAPI reads the file
$OH/config/ias.properties

It gets the values like ,

OIDhost=incq128ad.idc.oracle.com
OIDport=3060
OIDsslport=3131
SSLOnly=false

This try to connect to the OID using the above and looks for the database defined in ,

InfrastructureDBCommonName=ORCL

For example , cn=ORCL,cn=OracleContext

From the above it gets the connect string from the attribute , "orclnetdescstring"

After this REP Api issues the SSL ldap queryto find out ,

orclReferenceName=,cn=IAS Infrastructure Databases,cn=IAS,cn=Products,cn=OracleContext

for example ,

orclReferenceName=ORCL,cn=IAS Infrastructure Databases,cn=IAS,cn=Products,cn=OracleContext

From the above it gets the value for the DCM and portal password etc ,

OrclResourceName=DCM,orclReferenceName=ORCL,cn=IAS Infrastructure Databases,cn=IAS,cn=Products,cn=OracleContext here it looks
for the attribute ,

"orclpasswordattribute" , usin this info the DCM connects to the database using the thin JDBC driver ,

Similiary the opmn will also connect to the database when the depandancies against the database are used.
