The VANWEBUI userid has full access to all profiles for accessing the key including FACILITY and RDATALIB classes in RACF. Still getting the same error:
Caused by: java.lang.IllegalArgumentException: ZOsSSLSocketFactory.alias_no_key_entry
Customer tried to use the other existing keyring with multiple certificates in it.
Verify if there are more certificates in the keyring. It is possible that tomcat is picking a different cert than the one you want to use.
If there are more certificates in the keyring, copy the label (alias) of the certificate in the keyring and add it to connector configuration in tomcat server.xml file (USS in file /path_to_vsp_runtime_dir/apache-tomcat-xx.x.xx/conf/server.xml) using attribute keyAlias="YOUR_CERT_LABEL".
The recommended approach is to create a separate keyring for Vantage StoragePoint web client it-self.
