Resource Manager Contact. The resource manager contact string is used by the GRAM Client to connect to, authenticate to, and request service from a GRAM resource manager. The simplest contact string is just a host name, but additional fields may be present in the name to qualify the TCP port number it is listening on, the service name (for example, to choose a specific scheduler), and the subject name (security identity) of the resource manager. For those resource manager contacts which omit the port, service or subject field the following defaults are used: The following contain all of the acceptable formats of a GRAM Resource Manager Contact: Note: Any of the above forms may be preceded by an optional '\<b\>https\</b\>\<b\>://\</b\>'.

## NAME

globus\_gram\_resource\_manager\_contact - Resource Manager Contact.

The resource manager contact string is used by the GRAM Client to connect to, authenticate to, and request service from a GRAM resource manager. The simplest contact string is just a host name, but additional fields may be present in the name to qualify the TCP port number it is listening on, the service name (for example, to choose a specific scheduler), and the subject name (security identity) of the resource manager.

For those resource manager contacts which omit the port, service or subject field the following defaults are used:

```
port = 2119 (assigned by IANA)
service = jobmanager
subject = subject based on hostname
```
