I see that with Informix 14.10FC8 we have a somewhat different onconfig explanation for the DIRECT_IO that what was used for Informix 12.10.FC10AEE:
New:
# DIRECT_IO - Set of flags that may be combined to control "special" I/O
# 0x0 = Neither direct I/O nor concurrent I/O is used
# 0x1 = Direct I/O is used if available
# 0x2 = Concurrent I/O is enabled (on AIX operating systems)
# 0x4 = Special I/O is enabled for TEMP DBspaces
###################################################################
Old:
# DIRECT_IO - Specifies whether direct I/O is used for cooked
# files used for dbspace chunks.
# Acceptable values are:
# 0 Disable
# 1 Enable direct I/O
# 2 Enable concurrent I/O
###################################################################
If I had set DIRECT_IO to 1 before, should I leave it as 1? Or should I change it to "0x1" for 14.10FC8?
