Was verursacht dieses Problem?

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.

Das System gibt eine Fehlermeldung aus und erlaubt Ihnen nicht, mit dieser Transaktion fortzufahren, bis der Fehler behoben ist.

'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.

Systemantwort

Wie behebe ich diesen Fehler?

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.
