Error occurred. Check the log /app/oracle/gc_inst/em/EMGC_OMS1/sysman/log/secure.log

Hmm emkey health not good. What does secure.log says now?

Caused by: java.lang.SecurityException: The jurisdiction policy files are not signed by a trusted signer!

        at javax.crypto.JarVerifier.verifyPolicySigned(JarVerifier.java:292)

        at javax.crypto.JceSecurity.loadPolicies(JceSecurity.java:317)

        at javax.crypto.JceSecurity.setupJurisdictionPolicies(JceSecurity.java:262)

What does this error message suggest?

jurisdiction policy files” suggest something wrong with Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy File.

What to do?

First check the java version, then download and copy the policy file accordingly.
$ $JDK_HOME/bin/java -version
java version "1.7.0_111"
Java(TM) SE Runtime Environment (build 1.7.0_111-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.111-b13, mixed mode)



and then copy below jars

US_export_policy.jar
local_policy.jar

to $JDK_HOME/jre/lib/security

 

Restart OMS Server
./emctl start OMS
