Resource Waiting in Transaction Processing

Scroll Prev Top Next More

You can determine how long R:BASE continues to retry the last command until it receives a resource lock. By default, R:BASE waits four seconds and tries to access the resource throughout the wait period. If the table or database is still unavailable when the wait period expires, a message is displayed. You can either retry the command, or roll back the transaction.

 

To change the wait period, specify a value in seconds for the WAIT setting; for example, enter:

 

SET WAIT 10

 

You can also specify how often R:BASE retries the command within the SET WAIT period. The maximum setting for the INTERVAL command (in tenths of a second) is nine; the default is five.

 

For example, to specify an interval of nine tenths of a second, enter:

 

SET INTERVAL 9
