Ojdeploy : Tuning exercise

First of all all the tuning I am doing is for out continuous integration server because I build time have hit 25 minutes on the solaris 11 machine (on my desktop the same build it takes 11 minutes).

So where I am working is in the "ojdeploy.conf" file located in [jdev location]/jdev/bin


Finding most java settings make a difference and mostly

Using jrockit I have got it down to 21 minutes

AddVMOption -Xmx1g
AddVMOption -Xms1g
AddVMOption -Xverify:none
AddVMOption -Djava.net.preferIPv4Stack=true

Fastest solaris build so far is on the standard 32-bit jdk - weighing in at 18 minutes

AddVMOption -Dapplication.handle.help=true
AddVMOption -Xmx1g
AddVMOption -Xms1g
AddVMOption -Dsun.awt.disablegrab=false
AddVMOption -XX:MaxPermSize=512M
SetJavaHome /usr/java
AddVMOption -Xverify:none
AddVMOption -Djava.net.preferIPv4Stack=true
AddVMOption -XX:PermSize=128m


will update with my findings but parameters like largePages, parallel gc, -server etc just seem to make things worse.


And the greatest build gain so far - using parallel ant tasks, cut my build time in half.

MANIFEST.MF merge JDeveloper for an executable jar

Goto your project > properties. Then click on deployment in the menu. Edit or add a jar deployment profile. Fill in the details under jar options (select Include manifest and give it a main class name) Also remember that the merge functionality only works with a BLANK line at the end of the merge file. REALLY this caught me. My merge file contents: Class-Path: commons-codec-1.3.jar [...empty line here CRLF...]

JBO-25013: TooManyObjectsException

oracle.jbo.TooManyObjectsException: JBO-25013: Too many objects match the primary key oracle.jbo.Key[Key null ]. Ok so for you it may be trying to insert a duplicate record this should explain your problem (also check trigger they could be the cause.) NOTE: You can also try to create a new duplicate EO if you have a page with two VO's using the same EO. This could sort your problems. For me I needed to add a launch listener on my LOV and clear the cache of my vo. LOV <af:inputListOfValues id="NameId" popupTitle="#{bindings.Name.hints.label}" value="#{bindings.RolName1.inputValue}" label="#{bindings.RolName1.hints.label}" model="#{bindings.RolName1.listOfValuesModel}" required="#{bindings.RolName1.hints.mandatory}" columns="#{bindings.RolName1.hints.displayWidth}" shortDesc="#{bindings.RolName1.hints.tooltip}" launchPopupListener="#{backingBeanScope.backingBean.launchPop...

ADF Encountered deferred syntax #{ in template text.

OracleJSP error: oracle.jsp.parse.JspParseException:  Error: Encountered deferred syntax #{ in template text.  If intended as a literal, escape it or set directive  deferredSyntaxAllowedAsLiteral This normally happens when you have some tag lib dependancy problems but this was  not the case for me... My problem: For some reason my model project had web stuff in it(public html etc)  so I had to remove the public html stuff from my project and manually edit the Model.jpr project file and remove the tag lib entries at the bottom o the file. Go figure.
