Issue/Introduction

Description:

Message:

NF5Z01 DB/DS: DYNAMIC/DDB STORAGE IS AT 80%

...may sometimes appear in the SSI Log followed by Message:

NF5Z02 DB/DS: DYNAMIC/DDB STORAGE SHORTAGE RELIEVED.

When looking at the output from the '/IPTEST' command (or the 'SELFTEST' command), the 'Percentage of Use' is different from that seen in the SSI Log:

=========================================================================================
Dynamic Database: Size = 64 MB Used = 72% High Used = 81%   
Synch Database: Size = 12 MB Used = 1% High Used = 1%   
Trace Database: Size = 128 MB Used = 1% High Used = 1%         
=========================================================================================

So are there some parameters to adjust for this?...

Solution:

Message 'NF5Z01' is a warning message indicating a threshold has been reached. The threshold value is set from PASSWTPCT Packet Analyzer parameter defined in SSIPARM member with a default of 80% within a range from 50 to 95 or NO.

Message 'NF5Z02' indicates the Packet Analyser DataBase (DB) DataSpace (DS) storage has dropped below the threshold that produces 'NF5Z01' messages. By default, the size of the Packet Analyzer Dynamic DataBase is set to 64 MB and is from a range of 8MB to 1024MB.

More information can be found, regarding the Packet Analyzer parameters, in the 'NetMaster for TCP/IP Reference Guide r11.7', chapter 5 on page 78.
