Error description
During checkpoint processing, message CSQP019I is written for each buffer pool. The message includes a count of the number of pages written by this checkpoint, but this count is incorrect at MQ V8.

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: The CSQP019I message reports a much * * lower than expected value for the * * number of pages written from a * * bufferpool to the pageset when a * * checkpoint is done. * **************************************************************** * RECOMMENDATION: * **************************************************************** CSQPDWP2 may need several passes over the bufferpool in order to calculate the number of pages written to the pageset for that particular checkpoint. However the code resets the number of counted pages on each pass and CSQP019I only reported the number written on the last pass.
Problem conclusion
CSQPDWP2 now correctly calculates the number of pages written to the pageset at checkpoint time. 000Y CSQPDWP2
