Can Log Analyzer read compression dictionaries in the log ?

Environment

z/os DB2

Resolution

Yes Log Analyzer is able to read the dictionary from the log. There is no option for that, the program reads the dictionary automatically, so you don't have to care about it.

However there is a limitation, that the dictionary must be read during the primary log read phase, no subsequent log read collects the dictionary data.
