JAVA_OPTIONS

different java options available to tweak your application or server to enable , disable any features
which one is not aware of, here I tried to collect and listed for everyone:

to set time zone at jvm level, define in env file
-Duser.timezone=EST

to start WLS managed server with local ldap
-Dweblogic.security.MSILocalLDAPOnly=true

to enable GC logs in WLS

-Xverboselog:C:/Oracle/../base_domain/gclogs/gc.log

to enable heap dump at OOM condition

-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=C:/Oracle/../base_domain/heapdumps"

SSL/TLSv1 related JAVA_OPTIONS

to enable JSSE
-Dweblogic.ssl.JSSEEnabled=true"

to enable SSL debug
-Dssl.debug=true -Dweblogic.StdoutDebugEnabled=true

to disable SSL in weblogic and enable TLS
-Dweblogic.security.SSL.protocolVersion=TLS1

to allow all TLS protocols for the most common SSLSocket or SSLSocketFactory classes:
-Djdk.tls.client.protocols=TLSv1,TLSv1.1,TLSv1.2

Applications using the HttpsClient or HttpsURLConnection classes can use the https.protocols system property:

-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2

to allow client/server to support a minimum protocol
-Dweblogic.security.SSL.minimumProtocolVersion=TLSv1.1
