The growth can be unrestricted or restricted to a fixed MB size. Though command line TSQL can create the files with space allocated in units (KB/MB/GB/TB). The wizard isn't quite as flexible. There can also be multiple transaction log files though I believe the virtual log files (logs within logs) extended through the additional files as needed as opposed to the circular log jumping that happens in Oracle. I think it is important as Oracle DBA's we have at least a conceptual knowledge of what SQL Server can and cannot do. So when management says they want to switch to SQL Server you have something to back up your opinions. I ran into this where the management was MSS/Win2K focused to the max I had to battle against them and the MS marketing guy. I won but it was a lot of work to prove my case. Actually, used application porting time/costs/metrics as DBMS/OS capabilities was a much harder sell. >From: STEVE OLLIG >Reply-To: ORACLE-L@fatcity.com >To: Multiple recipients of list ORACLE-L >Subject: RE: MS SQL hasn't given up! >Date: Fri, 28 Feb 2003 12:49:29 -0800 > >no problem Rich. the transaction log mirroring can be done by the DBMS. >and SQueal Server has disk devices much like a tablespace that can be >placed >on different disks and such. transaction logs are kind of like tables in >that they must be placed in a device. so yes, these mirrored transaction >logs can be kept apart and "safe". > >Rachel's comment is also accurate however. if things go way wrong (usually >happens to a novice dba) the transaction log can get stuffed so full that >there's no way to "archive" it and you end up "truncating" it. users tend >not to like it when they can't do DML ;-) anyway, once a transaction log >has been truncated there is no transaction recovery until the next database >backup completes. and yes - the database backup utility does hot backups. > > > -----Original Message----- > > From: Jesse, Rich [SMTP:Rich.Jesse@qtiworld.com] > > Sent: Friday, February 28, 2003 1:47 PM > > To: Multiple recipients of list ORACLE-L > > Subject: RE: MS SQL hasn't given up! > > > > Steve, when you say "mirror" are the writes duplicated from SQueaL >Server > > or > > hardware?
