User-defined Substitution Variables
Define your own substitution variables by using the ## define statement. The name of the substitution variable can only contain alphanumeric characters and underscores.
You can optionally specify a value when you define your own substitution variables. The value can be a string or a Boolean expression. If you do not specify a value in the ## define statement, the $variable is created with no value.
Vision predefines the following substitution variables in the template file "intopdef.tf". You can change the value of these substitution variables by editing the "intopdef.tf file."
$_deadlock_retry
Indicates the number of times the application retries the transaction if there is a deadlock error. The default is 2.
$_deadlock_error
Indicates the error code for a deadlock error. The default is the generic error code, 49900. If you are using dbms error codes, change the value of this variable to 4700, the dbms error code for deadlock.
$_timeout_seconds
Indicates the length of the time-out period in seconds. That is, the number of idle seconds before any on_timeout escape code is executed. The default is 300 seconds.
