'Tuner Blog

Hi all!  I skipped an entry last month, but did actually post a new template & rule set.  This month we're adding 9 new rules bringing our two month total to 14.  Here's what we put up last month:

• HTTPEnableThreadDebug allows admins to indicate various levels of logging for HTTP threads.

• Debug_Logger_Buf_Full_No_Wait, Debug_Logger_Buf_Full_Min_Wait, Debug_Logger_Buf_Full_Max_Wait can all improve performance when transactional logging is enabled.
  

• Log_DisableTXNLogging prevents transaction logging from logging entries in log.nsf.

Here's what we're adding this month:

• a new DEBUG_PD_NAGLE_OFF rule, specific to iSeries running Domino version 8.0 and 8.0.1

• another iSeries specific rule JavaUseClassicJVM which applies to Domino versions 8.5 and later (this should not be set)

• the final iSeries specific  rule, NSF_BUFFER_POOL_SIZE_MB which will check for the pre-set value of 300MB and alert if a conflicting value is set.
  

• two settings which should only be used when instructed by IBM Support: DEBUG_DIRECTORY_CACHE (used for debugging DbDirMan issues) and DEBUG_GROUP_CACHE (used for debugging authentication issues)

• finally, four flavors of 'Server_Max_Noteopen" all designed to allow for administrative control over howmuch Domino memory is used for open notes for a given server process.  There are two versions of Server_Max_Noteopen_Memory_MB, one for Domino versions 7.0.2 and earlier, one for Domino 7.0.3 and later.  Likewise, there are two versions of Server_Max_Noteopen_Memory_KB, one for Domino versions 7.0.2 and earlier, one for Domino 7.0.3 and later.  Of course, the big differentiator is whether the value is specified as Megabytes or Kilobytes; it should be noted that if Server_Max_Noteopen_Memory_MB and Server_Max_Noteopen_Memory_KB are used,
  Server_Max_Noteopen_Memory_MB will win.

Finally, I'd be remiss if I didn't acknowledge the much appreciated feedback that has started to come in.  A special shout out to Bruce Currier and Ulrich Krause who provided feedback and testing to help me fix a version awareness issue we had with the DEBUG_PD_NAGLE_OFF rules (included in this rule set.)  Also a huge "Thanks!" to all who have been contacting me with rule ideas, providing feedback via email and in the forums.  Keep it coming!
