How to solve slowness issues in J Developer 12.2.1.3

Is your JDeveloper 12c too slow, follow these 3 basic steps and increase perfomance of JDeveloper 12c (12.2.1.3)

Step 1: Configure JVM settings in jdev.conf

Path: $MV_HOME$/jdeveloper/jdev/bin/jdev.conf

# optimize the JVM for strings / text editing

AddVMOption -XX:+UseStringCache

AddVMOption -XX:+OptimizeStringConcat

AddVMOption -XX:+UseCompressedStrings

# if on a 64-bit system, but using less than 32 GB RAM, this reduces object pointer memory size

AddVMOption -XX:+UseCompressedOops

# use an aggressive garbage collector (constant small collections)

AddVMOption -XX:+AggressiveOpts

# for multi-core machines, use multiple threads to create objects and reduce pause times

AddVMOption -XX:+UseConcMarkSweepGC

AddVMOption -DVFS_ENABLE=true

AddVMOption -Dsun.java2d.ddoffscreen=false

AddVMOption -XX:+UseParNewGC

AddVMOption -XX:+CMSIncrementalMode

AddVMOption -XX:+CMSIncrementalPacing

AddVMOption -XX:CMSIncrementalDutyCycleMin=0

AddVMOption -XX:CMSIncrementalDutyCycle=10

Step 2: Configure Jdeveloper memory settings in ide.conf

Path: $MV_HOME$/jdeveloper/ide/bin/ide.conf

# Set the default memory options for the Java VM which apply to both 32 and 64-bit VM's.

# These values can be overridden in the user .conf file, see the comment at the top of this file.

AddVMOption -Xms2048M

AddVMOption -Xmx4096M

remove settings from users file.

Step 3: Go to tools preferences, code editor and save action  Disable "Build After Save"

Dear All,
              I have successfully passed Oracle ADF 12c Certification examination. It was a very knowledgeable experience of giving 12c certification examination. 12c test was  very well organized as compared to 11g.
You can pass it only if you have development experience with theoretical knowledge. If you need further assistance feel free to contact with me. Kindly don't go for dumps they will surely leads towards failure.

ADF Certification

Dear All,
            I have completed my Oracle ADF Certification. Now I am Oracle ADF 11g Certified Implementation Specialist.I have never used any dump for exam preparation only focused on key concepts of ADF. Currently I am giving ADF trainings in Faisalabad and Lahore Pakistan anyone wants to get certified can contact me any time.

Show exact length of Secret data or Password in JSF Page in ADF

I have seen many posts about finding the solution of displaying exact length of password data in jsf page.
many people try to use af:inputText with secret=true; but fail and think that this is a bug from oracle.
I don't think this is bug this could be policy to increase security of data.

But If  there is a requirement from client to show exact length of secret data what to do know.
I have prepared a simple solution for this.

• create a view object or bean with property named password and type String.
• add this view object in data control.
• create a jsf page.
• add html component input secret like <h:inputSecret id="is1" value="" redisplay="true" immediate="true"/>
• bind value of input secret with view object property by going into page bindings or create a bean and bind with this bean like <h:inputSecret id="is1" value="#{bean.password}" redisplay="true" immediate="true"/>
• redisplay property should be set to true.
• deploy and test
