Explanation

One or more log streams defined to a structure has encountered a structure entry threshold condition. This means that the structure had 90% of the entries in use at one time. When the entries reach 100%, write operations to all of the log streams in the structure fail until the full condition is resolved. Applications using the affected log streams might experience a slow down or possibly an outage if the condition is not resolved timely.

This condition might not indicate a problem for a log stream that does not share its structure with other log streams. Also, a log stream indicated below might be the consequence of a misconfiguration of another log stream that resides in the same structure as the listed log stream.

In the message text:
start date
The time the check begins reporting conditions on in mm/dd/yyyy hh:mm:ss format. This value varies based on the input parameters: for ALL, it defaults to the time logger started; for TIME(value), it represents the requested value.
For each affected log stream, the report details are:
  • The log stream
  • The structure the log stream resides in
  • The count of the number of entry threshold reached conditions encountered for this log stream on this system
  • The timestamp of the last entry threshold reached for the log stream.

The report keeps track of the most recent 16 entry threshold conditions that occurred. A log stream is reported only once in the list for entry threshold conditions, but might also have structure full or staging data set full conditions.

System action

The system continues processing.

Operator response

Report this problem to the system programmer.

System programmer response

Consider taking one or more of the following actions:
  • Resolve any log stream offload constraints.
  • Use the CFSizer to determine an appropriate size for the structure. Update the CFRM policy accordingly.
  • Decrease the HIGHOFFLOAD for the affected log streams.
  • Increase the LOWOFFLOAD for the affected log streams.
  • Move some log streams to a new structure if there are multiple log streams in the structure.
  • Ensure that log streams in the structure have a similar entry to element ratio. If they do not, consider moving the odd log stream to another structure.

After correcting a log stream condition, consider using the MODIFY command to update the 'TIME(mm/dd/yyyy hh:mm:ss)' parameter to a time after this condition occurred so it is no longer displayed as an exception. See the IBM Health Checker for z/OS User's Guide for instructions on updating the parameters of the check.
