Problem while injecting Dynatrace agent into WebLogic App Server 11g
Dear friends,
I am new to Dynatrace set up and facing the issue while injecting host agent into Web Logic server's startWebLogic.cmd file.
Line to copy and paste from Dynatrace clipboard to startWebLogic.cmd, startManagedWeblogic.cmd and startNodeManger.cmd files is,
-agentpath:"C:\Program Files\Dynatrace\Dynatrace 6.5\agent\lib64\dtagent.dll"=name=OracleWebLogic_Monitoring,server=xxxMyComputerName:9998
Issues while configuring dynatrace are,
Case 1 : If I copy same line and continue,
My application will run successfully, but Web Logic Agent will not get added in Dynatrace
Case 2 : If I copy the above line after replacing lib64 to lib,
My application will not run properly(i., few navigation links are getting disabled), but Web Logic Agent will get added in Dynatrace.

Few other observations are,
- I did not find the file “C:\Program Files\dynaTrace\Dynatrace 6.3\agent\conf\dthostagent.ini” in my local system.
- Will this file be get generated while installation? Or
- Will this file be get generated while configuring Dynatrace?
- I have created new sample file manually with Host agent entries as per resources from Google. Please find the file content of dthostagent.ini as,
# The name of the host agent (used for agent mapping on the dynaTrace Server). # Default: host Name OracleWebLogic_Monitoring # The address of the dynaTrace Collector this agent should connect to. # The address is of the form host:port, e.g. exampleserver:9998 # Default: localhost Server my-5028-xyz:9998
- While installing and after installation of Dynatrace software ( dynatrace-full-6.5.0.1247-x86-64.msi), we did not face any steps like agents installation.
I am using below mentioned s/ws.
[ERROR][load ] Could not load library C:\Program Files\Dynatrace\Dynatrace 6.5\agent\lib64\dtagent.dll
D:\Data\NS\Setup\Apache2.2\bin>
Please suggest me to find out the root cause of the issue and it's resolution.
Hi Dynatrace Users, Would you please look into the above mentioned issue? Is it compulsory to have all agents ( Servers and JVM) should belongs to same bit type like either 64-bit nor 32-bit? If it is not compulsory, then why I am unable to run properly both my application and local Dynatrace Server at same time.
Vijaya, I've moved your question to the AppMon & UEM Open Q&A forum, where people who can help you with this issue will see it.
Hi All,
Still I am facing same problem even after I made all my JVM and servers software to 32-bit.
The issue is, after injecting a server agent into my Web Logic Server, my application will not work properly. Few right navigation links and body of that links will not be displayed.
Is there any security settings I need to do along with agent injection in Web logic configuration ?
Hi All,
I have been facing the same issue since last one month.
Is there any security settings in Web logic/Apache/Browsers/JVM/Application-code, do I need along with agent injection in Web logic and Apache servers? if yes, please mention those settings.
If not, dynatrace is not a suitable tool to monitor all high secured enterprise/web applications.
Would anybody suggest/finalize this question?
Hi Vijaya,
This issue looks like it may be better serviced by our support team. If you haven't already done so you can submit a ticket at our support portal here.
After support helps resolve this issue for you could you post in this thread again with the solution? It might help someone else in the future.
Hope this helps,
Dan
So did you get this solved?
I found the support case, it looks like they were injecting an agent with the incorrect bitness (it was a 32 bit application and the agent they were using was 64 bit).
