Home -> Community -> Mailing Lists -> Oracle-L -> Re: MAXTRANS ignored
Hi!
I remember from somewhere that in 9i, mintrans is 2 for tables as well, like for indexes in past. Thus maxtrans is minimum 2 as well, even if you set it to 1 explicitly. You can verify it from blockdump, there's 2 ITL entries in block even when you have had only one transaction there. So you should try to do at least 3 *updates or deletes* in different transactions in a block. If you do inserts then a new block is just allocated when ITL list is full...
