Table 1-5. System Procedure Calls
Procedure Call Description
ABORTTRANSACTION Cancels a transaction. When a process calls this
procedure, TMF backs out the database changes
associated with the current transaction.
ACTIVATERECEIVETRANSID Permits multithreaded servers to read requests from
$RECEIVE before replying to previously read
$RECEIVE requests.
BEGINTRANSACTION Starts a new transaction and creates a new
transaction identifier for the process.
COMPUTETRANSID Converts the individual numeric components of a
transaction identifier to a transaction identifier in
internal format.
ENDTRANSACTION Commits the database changes associated with a
transaction identifier. If the action completes
successfully, the changes made by the transaction
are permanent.
FILE_GETINFO[LIST][BYNAME] Returns information about a file, including whether the
redo or undo phases of file recovery are required to
return the file to a consistent state.
GETTMPNAME Obtains the name of the transaction management
process.
GETTRANSID Returns the current transaction identifier of the calling
process.
INTERPRETTRANSID Converts a transaction identifier in internal format to
its numeric components.
RESUMETRANSACTION Restores as current a transaction identifier created by
a previous call to BEGINTRANSACTION.
STATUSTRANSACTION Returns the transaction state of the current
transaction or that of a specified transaction.
TEXTTOTRANSID Converts a transaction identifier from its external
ASCII form to internal format.
TRANSIDTOTEXT Converts a transaction identifier in internal format to
its external ASCII form.
