Db2 Mirror

This wiki page contains a description of the enhancements made to IBM Db2 Mirror for i by PTF Group level and year. Instead of listing individual PTFs, updates to Db2 Mirror are denoted by the Db2 Mirror PTF Group level in which the enhancements are enabled.

Use the WRKPTFGRP (Work with PTF Groups) CL command or the QSYS2.GROUP_PTF_INFO view to list the current Db2 Mirror PTF Group level for your node:

SELECT CHAR(PTF_GROUP_NAME, 7) AS GRPPTF, PTF_GROUP_LEVEL   
    FROM  QSYS2.GROUP_PTF_INFO 
    WHERE PTF_GROUP_NAME IN ('SF99961', 'SF99951', 'SF99668')
      AND PTF_GROUP_STATUS = 'INSTALLED'
    ORDER BY PTF_GROUP_LEVEL DESC LIMIT 1;

For a complete list of Db2 Mirror updates, enhancements, and improvements, see the What's new section within the IBM i Documentation for each corresponding release:
