All Environments

The Mainframe HUB must be configured to use the Mainframe Logger and run in the same LPAR as the Substation ES, Batch, CICS or IMS region.
The 4 character HUB name "YODA" is determined from a DDName as follows:
```
//HUBYODA DD DUMMY
```
If the HUB name is not specified, the LPAR name is used as the HUB name.
TIBCO recommends to use a specific name for the HUB that is different from the name of any running LPAR, especially when different versions of the TIBCO software stack execute in the same LPAR.
