Paul - The answer is: check your "Machine Specific Notes" in $INFORMIXDIR/release/ONLINE_7.? The following is from the file for our HP10.20 / 7.23.UC4 machine -- I am sure that the ONLINE_7.? file on you AIX box has a similiar section: [included section begins] An environment variable IFMX_HPKAIO_NUM_REQ is provided to specify the number of simultaneous KAIO requests that are processed by the server at one time. The value can be set in the range of 10 to 5000, the default being 1000. If the error "KAIO: out of OS resources, errno = %d, pid = %d" occurs, consider increasing the value of IFMX_HPKAIO_NUM_REQ. IFMX_HPKAIO_NUM_REQ=2300; export IFMX_HPKAIO_NUM_REQ (for Bourne or Korn Shell) setenv IFMX_HPKAIO_NUM_REQ 2300 (for C Shell) [included section ends] Hope this points you in the right direction.
