Re: How can I display images from a mySQL Database in a web page?

2003-07-15 Thread colbey
THis is kinda offtopic.. it depends on what frontend you are using to access mysql (php,java,perl,etc) .. You just need to pull the binary data and output it with the correct http headers and it will show up in a browser.. search the list for more info. www.php4.com has an example using php..

2003-07-10 Thread colbey
Lord yea... don't get me wrong it would be nice.. but I'd start with say 1GB based on what your doing now.. just make sure the server has lots of slots open for future upgrades if required. (don't let them stick in 256MB sticks taking up 4 slots).. use larger size sticks to keep slots open..

Re: NAS vs SAN for data directory

2003-07-08 Thread Blair Colbey
Avoid NAS... that's like dealing with mysql via NFS ... Internal raid depending on controller type and disk configuration could be faster than an external SAN... But chances are external SAN has alot more scalability as far as adding more controller, cabinets and disks... If it was my choice

I just assumed your question was for mysql data only.. If you want total I use: OS - raid 1 (2 X 18.2gb - 10kRPM) DATA - raid 0+1 (# X 18.2gb - 15kRPM) usually a dataset is comprised of 6-10 disks.. you could go larger with the drive size.. but more spindles = more thruput Swap isn't much of

Re: Optimal Disk Configuration

My favourite for dedicated db servers (good amount of data, but a ton of access, queries/sec) is raid 0+1 ... fast access, but requires a good number of disks.. Be sure to use a good raid controller, multiple channels for the disks if possible.. On Sat, 5 Jul 2003, Jim McAtee wrote: What

I'd instead setup a 2nd backup server that's a slave to the master, replicates all the time, keeps in sync. At X time, stop replication/mysql, backup data to tape .. restart mysql and it will catch up/re sync back to master.. On Thu, 26 Jun 2003, SAQIB wrote: mysqlhotcopy does your locking

Depending on size of data there are a few different methods... Just like what most people do.. use plain insert statements with the data properly escaped and shouldn't have any problem going in. Pulling data out is pretty quick .. I can stream binary data out of my mysql storage servers via our
