Parameter
rdisp/wp_max_no
Short text
Maximum number of startable work processes
Parameter Description
The parameter rdisp/wp_max_no defines the maximum number of work processes that the server can start and therefore defines the size of the internal process table.
During the start-up of the server, the work processes resulting from the following parameters are started: rdisp/wp_no_dia, rdisp/wp_no_vb rdisp/wp_no_vb2, rdisp/wp_no_enq, rdisp/wp_no_btc, and rdisp/wp_no_restricted. The total of the parameters must be smaller than or equal to the value of parameter rdisp/wp_max_no.
If the operating mode is switched, the number of individual process types can be changed. The criterion that the total must not exceed the value of rdisp/max_wp_no still applies.
The “new” possibility of creating processes dynamically is also used for handling deadlocks. If all the processes of a type, such as dialog, are in the status “On Hold”, a process with this type is restarted, if possible. After the bottleneck has been resolved, the dynamic process is stopped again. For more information, see the documentation for the parameter rdisp/dynamic_wp_check.
To remain compatible with “old” configurations, you can assign the value DEFAULT to the parameter. In this case, the value of the parameter is the total of the above parameters plus 2.
