Hi All,

I have kicked of a script handed to me by developers on a test environment (9.2.0.8 on Solaris) and it takes a long time to run 12+ hours

It renames , creates and alters tables and creates indexes.

I'm getting following wait events as the top 5

The top 2 I already looked at and think can be explained by not doing any direct inserts
There is an alter session to enable parralel execution but the tables are noparallel so no direct inserts.
But it's the 3rd one that I can't get much info on when I google

Anyone have pointers where I can go for that one?
