To generate the stores for GoldenGate, you need to create 1 JKS keyStore. To generate those files, you can use the "keytool" command from the JDK or using the free tool KeyTool IUI (last known version in 2.4.1).
Create one jks KeyStore (server.jks) with one Private Key Version 3 using RSA algorithm. Use this KeyStore as KeyStore for the Server. To do that, suing KeyTool IUI:
1) Create an empty KeyStore
2) Create a Private Key Version 3 with RSA algorithm added to this KeyStore
