Last updated on NOVEMBER 23, 2015

Applies to:

MySQL Enterprise Monitor - Version 2.3 to 2.3 [Release 2.3]
Information in this document applies to any platform.
This issue only occurs in MySQL Enterprise Monitor (MEM) 2.3, it does not occur in higher versions (eg. MEM >= 3.0).

Goal

Using mysqldump with --single-transaction it's observed that there are frequent reorganize statements in the MySQL Enterprise Monitor (MEM) 2.3 repository database like:

ALTER TABLE `mem`.`dc_p_long` REORGANIZE PARTITION `p1100` INTO ( PARTITION `p1100` VALUES LESS THAN....

locking the entire MEM interface when the backup of this table is in progress.

Backup on this table took hours together and MEM is not able to send any alerts during this time in case of any events happenings.

How to overcome this issue?
