Is there any way to set a JVM args like -Djava.net.preferIPv4Stack=true at cell level in order to apply/pass all JVM at cell in Websphere Application Server?
Yes, through wsadmin scripting. There's a script here: https://www.ibm.com/developerworks/community/blogs/Dougclectica/entry/wasadmin_script_to_set_websphere_jvm_properties7?lang=en
