Tune your JDeveloper 12c (12.1.3)

Is your JDeveloper 12c too slow, follow these 3 basic steps and increase perfomance of JDeveloper 12c (12.1.3)
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

Step 3: Disable "Build After Save"
1. Go To Tools->Preferences->Code Editor->Save Actions
2. Remove "Bild Project After Save"

Variables x=3 y='Hello' Note: there should be no space in assigning variables. Print Variables: echo $x echo $y More accurate printing variables is double quote your variables echo "$x" echo "$y" You can print literal also with variables. echo "Value of variable x is $x" If  else statement x=5 y=7 if [[ $x -lt $y ]]; then echo "true" else echo "false" fi Note : For good practice, put condition in [[...]]. There is semi-colon ; after condition end. fi command indicates closing of if else statements. For comparison, use -lt,-gt, -le, -ge comparison parameters for good practice if ((x>y)); then --- this also works -- Try yourself Nested if else can be done with using elif command x=cool if [ "$x" = "cool" ] then     echo "Cool Beans" elif [ "$x" = "neat" ] then     echo "Neato...
