+ Installation Process +

This chapter describes how to install + cosTransactions + in an Erlang Environment. +

+ +
+ Preparation +

Before starting the installation process for cosTransactions, + the application Orber must be running.

+

The cosTransactions application must be able to log progress to disk. The log files are + created in the current directory as "oe_name@machine_type_timestamp". Hence, read and + write rights must be granted. If the transaction completes in an orderly fashion the + logfiles are removed, but not if an error, which demands human intervention, occur.

+
+ +
+ Configuration +

When using the Transaction Service the cosTransactions application + must be started using either cosTransactions:start() or + application:start(cosTransactions). +

+

The following application configuration parameters exist:

+ + 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. + +

Then the Transaction Factory + must be started:

+ + cosTransactions:start_factory() - starts and returns a reference to a factory using default configuration parameters. + cosTransactions:start_factory(Options) - starts and returns a reference to a factory using given configuration parameters. + +

The following options exist: +

+ + {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 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. + +

The Factory is now ready to use. For a more detailed description see Examples. +
