在11.70中加入了FULL_DISK_INIT 这个参数，对当前已经初始化的dbspace进行保护，若是需要初始化dbspace，需要更改这个参数为 1 . 回复 2# liaosnet
多谢指点，将FULL_DISK_INIT参数修改为1，然后初始化oninit -iv就会成功。
但还有个问题，我关闭onmode -ky后，从新初始化时FULL_DISK_INIT又会自动变为0；
再次请教如何将FULL_DISK_INIT参数写死，不用每次启动的时候都去修改？？？ 本帖最后由 liaosnet 于 2011-04-26 23:45 编辑

只要初始化成功了，该参数就自动变为0.
BTW： 以后启动就不需要使用-i 这个命令了，直接使用oninit -v 就行了。 -i 只需要在第一次初始化的时候使用。。 回复 4# liaosnet
多谢指点，问题已经解决，谢谢了。 学习！！！！ 学习了 学习了啊。 回复 4# liaosnet
