NAME¶
cosTransactions - The main module of the cosTransactions application.DESCRIPTION¶
To get access to the record definitions for the structures use:- *
- maxRetries - default is 40 times, i.e., if a transaction participant is unreachable the application will retry to contact it N times. Reaching the maximum is considered to be a disaster.
- *
- comFailWait - default is 5000 milliseconds, i.e., before the application retries to contact unreachable transaction participants the application wait Time milliseconds.
EXPORTS¶
start() -> Return
Types:
Return = ok | {error, Reason}
This operation starts the cosTransactions application.
stop() -> Return
Types:
Return = ok | {error, Reason}
This operation stops the cosTransactions application.
start_factory() -> TransactionFactory
Types:
TransactionFactory = #objref
This operation creates a Transaction Factory. The Factory is used to
create a new top-level transaction using default options (see listing
below).
start_factory(FacDef) -> TransactionFactory
Types:
FacDef = [Options], see Option listing below.
TransactionFactory = #objref
This operation creates a Transaction Factory. The Factory is used to
create a new top-level transaction.
The FacDef list must be a list of {Item, Value} tuples, where the following
values are allowed:
stop_factory(TransactionFactory) -> Reply
- *
- {hash_max, HashValue} - This value denotes the upper bound of the hash value the Coordinator uses. Default is 1013. HashValue must be an integer.
- *
- {allow_subtr, Boolean} - If set to true it is possible to create subtransactions. Default is true.
- *
- {typecheck, Boolean} - If set to to true all transaction operation's arguments will be type-checked. Default is true.
- *
- {tty, Boolean} - Enables or disables error printouts to the tty. If Flag is false, all text that the error logger would have sent to the terminal is discarded. If Flag is true, error messages are sent to the terminal screen.
- *
- {logfile, FileName} - This function makes it possible to store all system information in FileName (string()). It can be used in combination with the tty(false) item in to have a silent system, where all system information are logged to a file. As default no logfile is used.
- *
- {maxRetries, Integer} - default is 40 times, i.e., if a transaction participant is unreachable the application will retry to contact it N times. Reaching the maximum is considered to be a disaster. This option overrides the application configuration parameter.
- *
- {comFailWait, Integer} - default is 5000 milliseconds, i.e., before the application retries to contact unreachable transaction participants the application wait Time milliseconds. This option overrides the application configuration parameter.
Types:
TransactionFactory = #objref
Reply = ok | {'EXCEPTION', E}
This operation stop the target transaction factory.
