java -jar fmw_12.1.3.0.0_wls.jar -silent -responseFile /home/weblogic/wls.rsp -invPtrLoc /home/weblogic/oraInst.loc

If your jdk is not set to global, you need to go to the jdk/bin directory to execute the last command.
IV. Creating Domains
Switch to / home/weblogic/Oracle/Middleware/wlserver/common/bin directory
Setting environment variables

export MW_HOME="/home/weblogic/Oracle/Middleware"
export WL_HOME="/home/weblogic/Oracle/Middleware/oracle_common"
export CONFIG_JVM_ARGS='-Djava.security.egd=file:/dev/urandom' 
//Then execute. / commEnv.sh 
//Re-execute. / wlst.sh  

V. Start up:

[weblogic@/home/weblogic]$ cd /home/weblogic/Oracle/Middleware/user_project/domains/base_domain/bin
[weblogic@/domains/base_domain/bin]$ ./startWeblogic.sh
