This parameter indicates the maximum number of DARI process that may reside at the database server. Once this limit is reached, no new DARIrequests may be invoked. This parameter is only applicable on database servers.
There can be no more than one DARI process active per coordinating agent, so the maximum number of DARI processes is also dictated by the maximum number of coordinating agents (max_coordagents).
Recommendation: If your environment features the use of the DARI facility within the database manager, then this parameter can be used to ensure that an appropriate number of DARI processes are available to handle the DARI calls made at any one time within the database manager.
If the parameter is set to -1, the maximum number of DARIprocesses will be the same as the value set in the max_coordagents parameter.
If you find that the default value is not appropriate for your environment because an inappropriate amount of system resource is being given to DARI processes which is affecting performance of the database manager, the following may be useful in providing a starting point for tuning this parameter:
maxdari = # of applications allowed to make DARI calls at one time
If keepdari is set to yes, then each DARIprocess that is created will continue to exist and use system resources even after the DARI call has been processed and returned to the agent.
If your environment is tightly constrained and you cannot afford the process resources associated with DARI, you can disable DARIby setting this parameter to zero (0).
