Error description

  • some port range maximum connections and divisor values
    changed in tcptr_aixpert after APAR IV28045 and
    companions.
    If tcptr_aixpert was run from an aixpert rule on the
    system before IV28045, the running tcp_aixpert after
    IV28045 will fail to change the maximum connections and
    divisor for these ports.
    Thus further check of the aixpert settings using
    aixpert -cp will fail with :
    tcptr_aixpert.sh: TCP TR controls are not set correctly
    

Local fix

  • after VI28045 has been applied manually run :
    tcptr -delete 1 12 256 1
    tcptr -delete 13 13 256 1
    tcptr -delete 14 20 256 1
    tcptr -delete 21 21 256 1
    tcptr -delete 22 25 256 1
    tcptr -delete 26 36 256 1
    tcptr -delete 37 37 256 1
    tcptr -delete 38 110 512 1
    tcptr -delete 111 111 256 1
    tcptr -delete 112 9089 512 1
    tcptr -delete 9090 9090 10 3
    tcptr -delete 9091 65535 512 1
    
    Then reapply the rule.
