RECON Thresholds parameters
Recovery Advisor uses RECON Thresholds parameters during analysis to detect RECON data set exceptions.
The RECON Reorg utility uses RECON Operational Controls parameters during execution to resolve RECON contention and request RECON backups. You can set these thresholds at host and IMSPLEX levels.
For RECON thresholds, the following general rules apply:
- To inactivate the threshold, specify 0 for the value.
- To use the inherited value, clear the value.
The folowing lists parameters in the RECON Thresholds category.
Parameter | Accepted values | Default value | Description |
|---|---|---|---|
RECON Thresholds category | |||
CI Splits % | 0 to 99 | 20 (indicates 20 percent of total CIs) | Specify whether Recovery Advisor detects that a RECON data set has exceeded the specified percentage of control interval (CI) splits, relative to the total number of CIs in the data set. |
CA Splits % | 0 to 99 | 20 (indicates 20 percent of total CAs) | Specify whether Recovery Advisor detects that a RECON data set has exceeded the specified percentage of control area (CA) splits, relative to the total number of CAs in the data set. |
Alloc Freespace % | 0 to 99 | 15 (indicates 15 percent of free space) | Specify whether Recovery Advisor detects that a RECON data set has less than the specified percentage of free space, relative to the allocated space in the data set. |
Extents | 0 to 253 | 1 | Specify whether Recovery Advisor detects that a RECON data set has exceeded the specified number of extents. |
Volumes | 0 to 58 | 1 | Specify whether Recovery Advisor detects that a RECON data set has exceeded the specified number of volumes. |
Data set size (tracks) | 0 to 9999 | 0 (indicates that this threshold is deactivated) | Specify whether Recovery Advisor detects that the number of tracks for a RECON data set has exceeded the specified number of tracks. |
PRILOG Record Size % | 0 1 through 99 Null | 0 | Specify whether to check for the condition in which an open PRILOG has exceeded the specified percentage (1 through 99) of the maximum 16-MB record size. Specify 0 to ignore this condition. Specify a null value to use the inherited value. |
RECON Warning Days | 1 through 366 Null | 45 | Specify the time period (in days, 1 through 366) that Recovery Advisor uses in calculations that forecast whether a RECON-related statistic will reach or exceed a threshold value within that time period. (If a statistic is forecast to reach or exceed the threshold, Recovery Advisor issues a warning-level exception.) Specify a null value to use the inherited value. |
RECON Detail Record Retention (days) | 1 through 32767 Null | Specify the maximum number of days (1 through 32767) that Recovery Advisor should retain a PRILOG status record for an open, online IMS system that is defined to Recovery Advisor. Recovery Advisor automatically deletes records that are older than this number of days. Specify a null value to use the inherited value. | |
Operational Controls category of the RECON Thresholds category | |||
RECON Data Set Contention - Resolution option | Depend on RECON Loss Notification WTOR to notify operators RMGR to notify IMS subsystems DELTA PLUS to notify IMS subsystems Fail utility with return code Fail utility with abend code Inherit | Fail utility with return code | Specify the action to take if the RECON Reorg utility encounters a RECON contention problem. If you select the WTOR to notify operators option, also specify the text of the WTOR message to be issued. If you select the Fail utility with abend code option, also specify the abend code to be issued. |
RECON Data Set Contention - Retry Time Period (Minutes) | Blank 0 10 20 30 40 50 60 | 20 | Specify the maximum amount of time (in minutes) that the RECON Reorg utility should wait or attempt to resolve RECON contention problems. If you do not want the utility to wait if RECON contention occurs, set the value to 0. To use the inherited value, set the parameter to blank. |
RECON Data Set Contention - Return Code | 0 to 99 | 12 | Specify the return code that the RECON Reorg utility issues if a RECON contention problem is not resolved. To use the inherited value, clear the parameter value. |
RECON Backup Data Set Name | Data set name(1 to 44 alphanumeric characters ) | none | Specify the data set name to use to back up the RECON data sets before the RECON Reorg utility performs any functions. To use the inherited value, clear the parameter value. If the inherited value is blank, no RECON backup is performed. |
