8815.0. "KAIO problem on DUnix 4.0b and Informix" by TLAV02::ORAPINL () Thu Feb 13 1997 01:17

    Hello,
    
    I have problem about KAIO out of resources error message on Informix
    7.20 UC4 with Digital UNIX version 4.0b.
    
    I found only patch to fix this problem on Digital UNIX v 3.2g.
    Could you pls tell me where I can find a patch for Digital UNIX v 4.0b?
    
    Thanks a lot in advance

	As far as I know patches are not needed for D Unix 4.0 or higher. Try to enlarge rt parameters aio-max-num and aio-max-percent in sysconfigtab: default values are very small Francoise

	That 3.2 patch is a backport of an obscure V4.0 feature for user by the KAIO function of Informix. As .1 says, check those aio system limits. I seriously doubt that you'll need to change aio-max-percent unless your trying to do 1000s and 1000s of concurrent aio operations on a very small memory platform -- a very impratical idea really.
