Use the DISPLAY LOGGER CONNECTIONS command to see if something unexpected is 
connecting. I always used syslog. If you only use OPERLOG, maybe SDSF or ??? is 
connected causing the delay.

OPERLOG contention

[Radoslaw Skorupka]

The following scenario:
z/OS 2.5, two-member parallel sysplex.

Sometimes I observe IXG251I and IXG284I
ISG251I informs the dataset is in use by another sysplex member
IXG284I says the dataset is PENDING DELETE.

It usually happens during log offload (archivization) using IEAMDBLG 
tool, however it is not predictable behavior.


The dataset is deleted later, so it is finally auto-resolved, however I 
think the above should never happen in normal circumstances.


Any clue?
