Quelle est la cause de ce problème?

This is a single 'performance' check and therefore does not
describe a critical system status. It is neither necessary nor
time-critical to perform the steps described below, but they could
help improve the overall performance of your R/3 System.

Le système émet un message d'erreur et ne vous permettra pas de poursuivre cette transaction tant que l'erreur n'est pas résolue.

'Foreground writes' occurred since the last time you started the
database. A 'foreground write' is necessary if an Informix user
thread (' light-weight process) does not find an empty or unmodified
buffer in Shared Memory therefore buffers have to be 'emptied' to
disk. This is very time-consuming and should be avoided if possible.

Réponse du système

Comment corriger cette erreur?

Check the number of 'page cleaners' (ONCONFIG parameter 'CLEANERS')
and ONCONFIG parameter 'LRU_MAX_DIRTY' after reading Note 41360.
To change an ONCONFIG parameter, edit the file
'$INFORMIXDIR/etc/$ONCONFIG' as user 'informix'.
CAUTION: The change will only become active when the database has
been started up.
