Dear All,

One of the database is having alert log of size 400Mb.

Though, we can rename it. Oracle will create the new one. But writing on same alert log would impact any performance issue?

Please provide your valuable inputs on it.

Thanks,

Regards,
Ashish Kumar Mahanta

Nothing that can be measurable.
But it is however recommended to split the file then if you have a problem with it (io error) you won't lose the whole data.

Thanks Michel,

I was having doubt on it. Now, it's clear. It's always recommended to split the file to smaller one.

And even if you don't have io errors etc opening and reading a 400M file in most text editors is a pain.
