APAR status
Closed as program error.
Error description
The situation is the following ... - A constantly growing table. - Table contains many bitmap pages. - There are many sessions inserting into the table at the same time. - An occasionally issue is seen at checkpoint. - Sessions/threads are forced to wait for access to a bitmap page whilst the owning thread also has to wait for the page to be retrieved from disk. - The sequential nature for accessing the bitmaps magnifies this problem when the I/O is slow. - As there is a need to be in critical sections to perform some of this work, it is an issue at a checkpoint and can lead to an instance being blocked. - A blockage of about 70 seconds has been seen.
