#    0 : cannot add logical log on the fly. (OFF)
#
# 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.

我直接把最前面的50M空间改成2G可以不
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 [1|2] ..

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。
