Problem summary
**************************************************************** * USERS AFFECTED: All DB2 users. * **************************************************************** * PROBLEM DESCRIPTION: Because dataset statistics in the * * IFCID 199 record for a given dataset * * are not extrenalized on every * * statistics interval, it may be * * challenging to keep track of what time * * frame a given dataset statistics * * section is covering given the existing * * design. A better solution is needed. * **************************************************************** * RECOMMENDATION: * **************************************************************** Dataset statistics in the IFCID 199 record are externalized only when a specific threshold for the usage of that dataset is met. As a result, these statistics are not guaranteed to be externalized for every statistic interval. Keeping track of when the last time statistics for a given data set were repprted can be a very difficult process for users and monitors, and a way to enable easier monitoring is needed. This issue exists only for IFCID 199 that are externalized as statistics records and not via IFI READS requests.
Problem conclusion
Temporary fix
Comments
New field QW0199SC has been added to the data section 3 of the IFCID 199. This field contains the timestamp of the last time the corresponding dataset statistics were externalized. If this is the first time statistics for this dataset are externalized, this value is a timestamp of when this dataset was opened.
