Re: Can't free logical logs

In my personal experience:
For other time, never reboot the machine or the Online, first backup
the logs! This is posibly in Online .03 and the next engines, i don't know
in 5.01.
Now only restore!! :-(
In this version of the online, long transaction is very dangerous!,
before of realize this, I set the continous backup of logical logs or set
the database to no-transactions. Other idea??
Along time ago, with Online 4.xx, fix the problem by this: (Only=
luck!)
1. First try restore the database, but, the Online say: logical logs
full wish backup?
2. And think this the solution, say yes, and push other data-tape,
and the Online backup some percent of the logs!
3. I repeat the first step and the second, until the logs are=
empty!!!
4. I don't needed restore the Database. Eureka!! Lucky!!
I don't try after of this time this experience, and know what this
is not correct!!
If you try, set to don't write mode the data-tape of the restore!!!
Take care of this!!! =20
Thanks. Gustavo
Note: Excuse the bad english!! :-)
