| Parameter : rdisp/configurable_wp_no |
------------------------------------------------------------------------
------------------------------------------------------------------------
| Short Description : Number of configurable work processes |
------------------------------------------------------------------------
------------------------------------------------------------------------
| Parameter description : |
| ----------------------- |
| This parameter specifies how many work processes of the types |
| dialog, update (including update2), background, enqueue, and spool |
| can be activated by an operation mode switch. This number should be |
| smaller than the maximum number of WPs so that the server can |
| generate temporary processes to resolve bottlenecks. (For more |
| information, see also documentation for the following parameters: |
| %%rdisp/wp_max_no%% |
| %%rdisp/wp_no_restricted%% |
| %%rdisp/dynamic_wp_check%% ) |
| |
| All numbers greater than 0 and smaller than or equal to the maximum |
| number of WPs are permitted as values. You can also assign the value |
| DEFAULT to the parameter. This means that the system calculates the |
| following schema: |
| configurable_wp_no = wp_max_no - wpsForDeadlockHandling |
| where |
| wpsForDeadlockHandling = |
| max (2, ((number of reserved WPs + number of dynamic WPs) / 4) |
| |
| Example: |
| %%rdisp/wp_no_dia%% = 16 |
| %%rdisp/wp_no_btc%% = 3 |
| %%rdisp/wp_no_vb%% = 1 |
| %%rdisp/wp_no_restricted%% = 2 |
| %%rdisp/wp_max_no%% = DEFAULT |
| %%rdisp/configurable_wp_no%% = DEFAULT |
| Then rdisp/wp_max_no = 22 + 2 = 24 |
| and wpsForDeadlockHandling = max(2,(2+2)/4)= max(2,1) = 2 |
| 2 WPs are therefore kept free for deadlock handling, and |
| rdisp/configurable_wp_no = 22. |
