#
# When dynamic logging is on, we can have higher values for LTXHWM/LTXEHWM,
# because the server can add new logical logs during long transaction rollback.
# However, to limit the number of new logical logs being added, LTXHWM/LTXEHWM
# can be set to smaller values.
#
# If dynamic logging is off, LTXHWM/LTXEHWM need to be set to smaller values
# to avoid long transaction rollback hanging the server due to lack of logical
# log space, i.e. 50/60 or lower.

[ 本帖最后由 lrg223 于 2008-11-25 14:56 编辑 ] 我直接把最前面的50M空间改成2G可以不:shock: :shock: :shock:
记得有个2047的限制。如果想让空间比2G大，要在哪改 在创建数据库之前，可以通过该参数设定基本的表空间大小，创建之后可以用onspaces添加chunk,这一点与Oracle数据库的表空间-》数据文件的含义是一样的 添加chunk,然后再写,不要超过2G 不能直接改那个参数。
就增加chunk，每个chunk大小不要超过2G，如果你用RAW的话，还要考虑offset。 改ROOTDBS的相关参数必须重新初始化..
支持大CHUNK,请使用onmode -BC ..:em17: :em17: 增加chunk！ 能写个增加chunk的语句吗，没加过:shock: :shock: :shock: 先自己建一个空白的 D:\IFMXDATA\xkzjservice\datadbs.ifxdbs这个文件（我随便起的名字）
假设你要在datadbs1 表空间上增加一个chunk
onspaces -c -d datadbs1 -p D:\IFMXDATA\xkzjservice\datadbs.ifxdbs -o 0 -s 500000
大小是500000KB，自己改啦。
