Use this page to set IMS database locking options.
To access this page:
When checked, enables the Internal Lock Resource Manager (IRLM) locking algorithm. IRLM locking more closely parallels mainframe IMS database DB locking behavior, reducing data constraint and potential for deadlock. Maps to the ES_IMS_IRLM environment variable.
When checked, creates a system dump when IMS DB control is unable to access a locked record before the specified Locked resource timeout period expires. Maps to the ES_IMS_DUMP_ON_TIMEOUT environment variable.
The number of seconds during which IMS DB control continues to retry a locked record before timing out. Valid values are 0 to 65535. The default is 30 seconds; a value of 0 indicates an indefinite wait time. Maps to the ES_IMS_LOCK_TIMEOUT environment variable.
