IDS 12.10 - dbimport very slow

Posted By: MARKUS BRINKBäUMER
Date: Tuesday, 25 June 2013, at 5:45 a.m.

Hello,

we have a new server (Windows 2012, 8 GB RAM, 4 x 600 GB SAS 15k HDD). On the server we have installed an IBM Informix Dynamic Server Version 12.10.FC1WE.

The database that should be moved to this server is not very big. The dbexport size is about 700 mb.

The dbimport took more then three days. On another server (with only one SATA 2 HDD and IDS 11.50) the import takes only 45 minutes. I tried to find out why the import takes three days to be completed, but I had no success.

I disabled the virus application (the ifmxdata-folder is already excluded), but that had no effect on the dbimport.

Is there anything we can change in the onconfig, to speed up the dbimport?
