In Response To: Re: Re: IDS 12.10 - dbimport very slow (John Miller iii)

Hi there,
Can help to check the size of the rootdbs ?
Probably the size is too small as compare to actual db space where the
database resides.
hope this help :-)

Just a few quick notes:

At this very instance the dbim= port is waiting on data to be read

from

the unload file. How fast= are the disks which the data sits on, are

they

the same disk which you = are inserting the data to??

In version 12.10 you can set a large cur= sor buffer. Since dbimport

uses

insert cursors this can really hel= p. FET=5FBUF=5FSIZE is an

environment

variable and is set in byte= s and you should set it to 64K or 1MB.

Prior

to version 12 the lar= gest it could be set to was 32K (again the

units is

bytes)

Set th= e environment variable FET=5FBUF=5FSIZE=3D1000000

I woul= d set these onconfig as they can help

DS=5FMAX=5FQUERIES 2

DS=5FTOTAL= =5FMEMORY 100000

DS=5FNONPDQ=5FQUERY=5FMEM 5000
