The define_default_pu command defines the PU that is the default for handling SNAP-IX management services data. Only one default PU for each node can be defined at any time; a second define_default_pu for a different PU name overrides the previous definition.
The define_default_pu command enables the user to define, redefine, or modify any field of a default PU. This command also enables the user to delete the default PU, by specifying a null PU name.
If an application issues the MS API verb TRANSFER_MS_DATA without specifying a PU name, the data is routed to the default PU defined for the local node and sent on this PU's session with the host SSCP. For more information about TRANSFER_MS_DATA, refer to the SNAP-IX MS Programmer's Guide.
Parameter name Type Length Default [define_default_pu] pu_name character 8 description character 31 (null string)
Supplied parameters are:
Name of the PU that is to be the default PU; for this definition to have any effect, this must be a PU name already defined as part of an LS definition. This name is a type-A character string starting with a letter.
To delete the default PU, specify all zeros.
A text string describing the PU. SNAP-IX uses this string for information only. It is stored in the node's configuration file and returned on the query_default_pu command.
No parameters are returned by SNAP-IX when this command executes successfully.
If the command cannot be executed, SNAP-IX returns a primary return code to indicate the type of error and a secondary return code to provide specific details about the reason for unsuccessful execution.
No parameter errors occur for this command.
No specific state errors, other than those listed in Common Return Codes from snaadmin Commands, occur for this command.
Common Return Codes from snaadmin Commands, lists combinations of primary and secondary return codes that are common to all commands.
