You are installing or upgrading to Automation Engine 12.1.1 and you are trying to make JCP work with HTTPS.
You created the certificates and the associated keystore but upon starting the JCP you get the error:
U00045101 The alias "jetty" does not exist in the keystore
Release : 12.1.x, 12.2.x and 12.3.x
Component : AUTOMATION ENGINE
To determine what your current alias is, execute the following command:
This command will return something similar to this:
Your keystore contains 1 entry
dedke01-ae1, Dec 3, 2020, PrivateKeyEntry,
Certificate fingerprint (SHA1): BE:3E:CD:C6:CC:53:28:B0:B2:02:60:14:DE:F4:A0:74:27:98:E7:D7
The value "dedke01-ae1" is the alias name in the keystore.
Note: If you upgrade to Automic 12.2.5 or higher and Automic 12.3.3 or higher -> you will have to convert the Java Keystore from JKS format to PKCS12.
