Re: Physical Log Boundedness...
To clarify: by bounded, I mean being limited by the ability to write to the disk fast enough to not block the CPU waiting for the I/O to complete. Greg wrote: > > Anybody got some good tricks to relieve Physical log boundedness when > doing massive Insert/Update/Deletes??? > > T…

Re: Q: Informix req. dedicated Host?
Databases and NFS both use lots of i/o. If you do not have lots of SCSI controlers I would separate the two services or get lots of i/o channels on one machine to handle both services. For a one box example, have 2 or more i/o channels for Informix disk arrays and 2 or more addi…

Re: Help! Poor performance
Jeff - what you are trying to do is optimize read performance of a large table. You're returning a result set of probably several hundred megabytes. To minimize response time, you want to light up every CPU, every disk, and use every megabyte of memory as hard as possible. Thi…

KAIO problem with Online 7.12 on AIX 4.1.4
I am currently using Online 7.12.UC1 on an AIX 4.1.4 platform. Because my dbspaces are created with raw device chunks, the I/O's should be performed by the KAIO threads. Thus, the I/O's should be performed by the CPU VP. However, when I issue the onstat -g glo command, I notice …

2Gb vs 4Gb Disks - Which is faster????
We are trying to decide whether to go with 2gb or 4gb HP drives for our database using Informix. The HP salesman says that the 4gb drives are faster than the 2gb drives which is probably true. What I would prefer though is to go with many smaller 2gb drives so that I can spread m…
