Jrocket and "[WARN] Use of -Djrockit.optfile is deprecated and discouraged"

Hello Technical Family,


In this post, I am going to discuss the Jrocket and its error during the Weblogic Startup. This Error may not impact the install but since it is deprecated - it make sense to fix it. I had to do some hours of research and would not want other people to do the same - hence posting here. What I get out of this - A pure satisfaction that someone out there will read this post and apply the solution. 


The platform is OS= RedHat 5.5 x86_64 with jrockit-jdk1.6.0_29-R28.2.2-4.1.0-linux-x64


Error:


During the Weblogic Server startup - I saw the following error in the logs:


[WARN] Use of -Djrockit.optfile is deprecated and discouraged.


Solution:


This is what I had to do, to get this issue gone from the logs and make Jrocket like what it wants to do.


1- I put the following into the environment variable in weblogic domain environment file.



-XX:+UnlockDiagnosticVMOptions  -XX:OptFile=${COMMON_COMPONENTS_HOME}/modules/oracle.jrf_11.1.1/jrocket_optfile.txt

2- Recreated the jrocket_optfile.txt as :

From:

- oracle/bpel/services/workflow/repos/driver/WFTask

- oracle/bpel/services/workflow/task/model/SystemMessageAttributesTypeImpl.*

- oracle/bpel/services/workflow/task/model/TaskTypeImpl.*

- oracle/bpel/services/workflow/task/model/SystemAttributesTypeImpl.*

- oracle/bpel/services/workflow/repos/Util.*

- oracle/xquery/parser/XPathTokenManager.*

To:

{

match: ["oracle.bpel.services.workflow.repos.driver.WFTask",

"oracle.bpel.services.workflow.task.model.SystemMessageAttributesTypeImpl.",

"oracle.bpel.services.workflow.task.model.TaskTypeImpl.*",

"oracle.bpel.services.workflow.task.model.SystemAttributesTypeImpl.*",

"oracle.bpel.services.workflow.repos.Util.*",

"oracle.xquery.parser.XPathTokenManager.*"],

enable: jit

}

Restart the Weblogic and you just resolved another issue.

Great feeling - right...

Enjoy life as it comes - It will be less of good times and more of bad times - but hey I try to find the refuge in solving the issue as I have yet to see the good time since last 11 years !!
