A Few Tidbits From The Under The Hood Sessions
As i promised in the earlier post "What I Learned At DEVCON" here are a few tidbits from the 2 Under the Hood sessions plus the Server Admin Under The Hood done by the SE’s and Server Team.
1. Do not continue to use recovered files.
2. The best CPU for FileMaker Server, especially if using Server Advanced, is a "medium powered" dual processor machine with 10K RPM SCSI drives. Use RAID where needed.
3. Be sure to turn off Disk Indexing and Shadow Copy and enable data throughput for network apps, not file services.
4. Nested or multiply referenced unstored calculations will result in many dependency re-evaluations and affect performance. Use Let function to prevent multiple re-evaluations.
5. FileMaker Servers should be rebooted at least once a week.
6. FileMaker Server is highly dependent on the underlying OS of the Server.
7. Do not activate automatic updates (Server patches, etc.) Automatic notification is OK, but do not install automatically as they require reboots that can cause problems for the files.
8. For the most part with modern CPU’s, set the server cache to the maximum amount and the flush interval to 1 minute. (Besides if the processor can’t handle 13 to 15MB flush per second to the drive, then you got other issues anyway.)
9. Segment the drives or use multiple drives for Server. OS on drive 1; data on drive 2; backups on drive 3.
10. Index is specific to the data type in FMP. And for all data types data are stored as compressed Unicode.
