Wie sehen bei euch die Statistiken zum NSF Buffer Pool aus?

[eknori]

sh stat database.database.bufferpool*

wie sieht das bei euch aus? Speziell der % Wert ist interessant.

[sral]

Das sind die Werte von meinem privaten Domino Server:

> sh stat database.database.bufferpool*
  Database.Database.BufferPool.Maximum.Megabytes = 364
  Database.Database.BufferPool.MM.Reads = 15
  Database.Database.BufferPool.MM.Writes = 5
  Database.Database.BufferPool.Peak.Megabytes = 363
  Database.Database.BufferPool.PerCentReadsInBuffer = 98,87
  5 statistics found

eknori, kriegen wir jetzt eine Auswertung ob unsere Werte gut oder schlecht sind?

Als Admin solltest du die Werte eigentlich interpretieren können.

Sieht bei allen gut aus; Martin sollte beim Interner WebApp-Server mal gucken, ob der Wert dauerhaft so niedrig ist. 93% ist so ziemlich der untere Grenzwert.

[m3]

Auf dem wird vor allem erstellt, weniger gesucht/gelesen. In dem Context sollte das passen.
