| Description: | Retrieves a previously stored value using $BFSetVar. Allows a value to be passed from one transaction to another in conjunction with $BFSetVar, or when value is used multiple times within a transaction. Each virtual user has its own variable space, so values are not shared between them. | 
| Parameters: | VarName-An alphanumeric identifier of the value stored. | 
| Syntax: | $BFGetVar("VarName") | 
| Example: | $BFSetVar("Totalrow", "2") $BFGetVar("Totalrow") ; if $BFSetVar sets the variable "Totalrow" to 2, $BFGetVar("Totalrow") returns the number 2. | 
| Description: | Returns the total number of nodes for all users. This function is intended only for Oracle clustering. |

| Example: | $BFMaxNode() ; returns: 2. This is the same value seen in the Number of Nodes field in Clustering tab for an Oracle profile. | 
| Description: | Returns the node number of the current user. This function is intended only for Oracle clustering. |
