How to retrieve .oamkeystore password in 11gR2PS3

While attempting to get the keystore password using listCred() wlst command, I got the below error:

wls:/oam_domain/domainRuntime> listCred(map="OAM_STORE",key="jks")
Traceback (innermost last):
  File "<console>", line 1, in ?
NameError: listCred


wls:/oam_domain/domainRuntime> help('listCred')
No help for listCred found. Please try help() for available options.

Oracle has removed listCred wlst command and is no longer available in OAM 11.1.2.3.0

To retrive the .oamkeystore password follow the below steps:

1) Log into to EM console, navigate to Weblogic Domain ->Domain Name ->System Mbean Browser 

Under Application Defined Mbean go to om.oracle.jps ->Domain:<domain_name> -> JpsCredentialStore ->JpsCredentialStore 

As shown

2) Click Operation tab and select getPortableCredential

 3) Enter both the parameters as shown

4) Click on Invoke to get the password
