SETTING TCP_SENDSPACE AND TCP_RECVSPACE ONLY APPLICABLE ON AIX PLATFORM |

| Problembeschreibung: |
APAR IZ33284 introduced setting the tcp_sendspace/tcp_recvspace
to minimum 64K.
Customers on Linux platform have come across this message which
should only apply to AIX platforms. Linux does not have kernel
parameters by these names. In Linux, the corresponding
parameters to tune are rmem_max/wmem_max and tcp_rmem/tcp_wmem.
It turns out that in Linux kernel 2.6 and later there is auto
tuning of these parameters, so we do not need to set them in
DB2 code. We are going to apply the above APAR to AIX only and
allow the Linux kernel to auto tune these parameters. |
