I have a customer using INGRES on a 8820 and he is experiencing a problem with is night jobs. They are batch jobs and they can't seem to get to use more than 50 % of the CPU. We analysed the ressources usage and found no real bottleneck that can explain the observed behavior. We suspect the application and/or Ingres but we can't proove it. I've been told that Ingres has problem with heavy loads, and that incorporating RDB in the picture would help. I need someone who's been through such problem that could guide me through that.

What do you meen by "batch job". is it 3gl with embedded sql, ABF/osl, or some utility. > ressources usage and found no real bottleneck that can explain > the observed behavior.

It is true that loading a table with 3GL program is problematic sience INGRES is doing at least 1, usually more I/Os per record, even if you commits every N'th record. The preffered way to load into INGRES is to use "copy" utility. Hope it helps Arie Levy |
