Generating Transactions Automatically (Implicitly)
Table 6-2 lists the valid use of TMF_OPTION constants and explicit transactions with
the various RSC/MP operations.
Do not specify the TMF_OPTION, SUCCESS_HI, or SUCCESS_LO options in the
[RSC] section of the RSC.INI file as your settings would be loaded into the default
options structure and used in any call to which RSC_DEFAULT_OPTIONS is supplied.
The handle of the option structure that contains TMF option values is supplied to the
RscWriteRead function. The TMF_OPTION, SUCCESS_HI, and SUCCESS_LO
options are sent with the RscWriteRead message in a single I/O to the host.
Table 6-1. Definition of TMF_OPTION Values
TMF Option Result
0 No automatic TMF operations.
1 RSC_BEGIN_TRANS Begins a TMF transaction before the TDP
sends the transaction request to the
target server.
2 RSC_END_TRANS Ends the transaction upon completion of
the TDP receiving the transaction reply
from the target server, if the server reply
code is between the SUCCESS_LO and
SUCCESS_HI options.
3 RSC_BEGIN_END_TRANS Begins a TMF transaction before the TDP
sends the transaction request to the
target server, and end the transaction
upon completion of the TDP receiving the
transaction reply from the target server.
