mi_integer mi_vpinfo_vpid(void)

The mi_vpinfo_vpid( ) function returns the VP identifier for the current VP. The current VP is the VP on which the current UDR is running. The VP identifier is a unique integer that the database server assigns to each active VP. The output of the onstat -g glo command displays the VP identifier for a VP in its first output column.

After you have a VP identifier, you can use the following DataBlade API functions to obtain additional information about the VP environment.

DataBlade API Function

mi_vpinfo_classid( )

VP-class identifier

mi_vpinfo_isnoyield( )

Does the current VP belong to a nonyielding VP class?

>=0

is the VP identifier for the VP on which the current UDR is running.

MI_ERROR

indicates that the function was not successful.
