Named angel

A named angel can provide authorized services to a select group of Liberty servers in the same way that the default angel provides authorized services to all Liberty servers. Learn the rules of defining a named angel and in what circumstances you can use it.

A named angel provides the following benefits:
  • An installation of Liberty can use its own angel. Therefore, the installation can be serviced without taking down all Liberty server instances on the LPAR.
  • Each stack product can configure its own angel instance that runs at the same service level as the stack product itself.

You can give an angel a name by coding the NAME parameter on the operator START command. The angel name is 1 - 54 characters inclusive, and must use the following characters only: A-Z 0-9 ! # $ + - / : < > = ? @ [ ] ˆ _ ` { } | ˜

The angel name must be unique on the LPAR. Two angels with the same name cannot be running concurrently on the LPAR.

You can have a maximum of 4092 named angels on an LPAR.

If the NAME parameter is omitted or blank, the angel receives no name. This angel becomes the default angel process for the LPAR. The default angel process can service Liberty server instances in the following situations:
  • Liberty server instances that run at V16.0.0.3 or earlier.
  • Liberty server instances that run at V16.0.0.4 and later and do not specify an angel name to which to connect.
