Appying patch from CLI

[jboss@7entOS sf_Downloads]$ jboss-cli.sh
You are disconnected at the moment. Type 'connect' to connect to the server or 'help' for the list of supported commands.
[disconnected /] connect
[domain@localhost:9990 /]
[domain@localhost:9990 /] patch apply jboss-eap-7.2.2-patch.zip --host=master
    "outcome" : "success",
    "result" : null,
    "server-groups" : null,
    "response-headers" : {"process-state" : "restart-required"}

[domain@localhost:9990 /]

As the CLI says, there is a restart pending, so:

[domain@localhost:9990 /] shutdown --restart=true --host=master
Failed to establish connection in 6557ms: WFLYPRT0053: No se pudo conectar a remote+http://localhost:9990. La conexión falló: Conexión rehusada
[disconnected /] connect
[domain@localhost:9990 /]

After this you can apply new patches if needed.

At boot logs you can check the patch level:

2019-10-10 13:10:48,096 INFO  [org.jboss.as.patching] (MSC service thread 1-2) WFLYPAT0050: El ID de parche acumulativo JBoss EAP es: jboss-eap-7.2.4.CP, parches one-off incluyen: none
