The counters for application-specific statistical values are to be reset. For this you must assign the data structure kc_curr_par_str to the data area.
Furthermore, you can enable or disable data compression, see section "Enabling/Disabling data compression".
Possible modifications
All the counters listed below can be set in one call. In order to reset the counters you must pass the value '0' to UTM in the relevant field, unless there is a note to the contrary. You can reset the following counters or statistical values:
Field name | Specification |
term_input_msgs='0' | Number of messages which the application received from clients or partner applications since the last reset. |
term_output_msgs='0' | Number of messages which the application sent to clients, printers or partner applications since the last reset. |
max_dial_ta_per_100sec='0' | Maximum number of dialog transactions carried out within the space of 100 seconds. |
max_asyn_ta_per_100sec='0' | Maximum number of asynchronous transactions carried out within the space of 100 seconds. |
max_dial_step_per_100sec='0' | Maximum number of dialog steps carried out within the space of 100 seconds. |
max_pool_size='0' | Maximum utilization of the page pool in percent since the last reset. |
avg_pool_size='0' | Average utilization of the page pool in percent since the last reset of the counter. |
cache_hit_rate='0' | Hit rate for pages in the cache memory since the counter was last reset (in percent). |
cache_wait_buffer='0' | Percentage of buffer requests in the cache, that led to a wait time. |
abterm_services='0' | Number of abnormally terminated services since the last reset. |
deadlocks='0' | Number of known and resolved deadlocks of UTM resources since the last reset. |
periodic_writes='0' | Number of periodic writes since the last reset (periodic write = backup of all relevant administration data in the UTM application). |
pages_pwrite='0' | Number of UTM pages saved on average in a periodic write. |
logfile_writes='0' | Number of requests to write log records to the user log file ((USLOG). |
maximum_jr='0' | In distributed processing only: |
max_load='0' | max_load specifies as a percentage the maximum load of the UTM application registered since the start of the application or the last reset. |
max_wait_resources='0' | max_wait_resources specifies the maximum conflict rate for user data locks over the application run. The value is specified as an amount per thousand. |
max_wait_system_resources='0' | max_wait_system_resources specifies the maximum conflict rate for system resource locks (system locks) across the application run. The value is specified as an amount per thousand. |
nr_cache_rqs='0' | Number of buffer requests taken into account to calculate the value cache_wait_buffer. |
nr_cache_searches='0' | Number of search operations for UTM pages in the cache taken into account to calculate the value cache_hit_rate. |
nr_res_rqs_for_max='0' | Number of requests for transaction resources in the 100 second period during which the maximum conflict rate max_wait_resources was reached. |
nr_sys_res_rqs_for_max='0' | Number of requests for system resources in the 100 second period during which the maximum conflict rate max_wait_system_resources was reached. |
avg_saved_pgs_by_compr='0' | Average value for the UTM pages saved per data compression. |
Period of validity / transaction management: type GIR ("KC_MODIFY_OBJECT - Modify object properties and application parameters")
If you wish to reset the statistical values listed above yourself, you should set MAX STATISTICS-MSG =NONE in KDCDEF generation. This stops UTM resetting the counters to 0 at hourly intervals and creating the statistics message K081.
Enabling/Disabling data compression
Field name | Specification |
data_compression='Y' | Data compression is enabled. For this purpose data compression must be permitted by means of UTM generation, see openUTM manual “Generating Applications”, MAX DATA-COMPRESSION= |
data_compression='N' | Data compression is disabled. |
Period of validity / transaction management: type GIR ("KC_MODIFY_OBJECT - Modify object properties and application parameters")
