Tracing SQL across the wire

This can be really useful in place of database tracing, especially when you want to see the action the *application* takes, and not just what it does in the database.

[user@************** common]# tcpdump -A -nn port 1521 | \
>                               awk '{if (tolower($0) ~ "select" || tolower($0) ~ "update") {p=1;print} \
>                                     else if(p == 1 && $0 !~ "^[0-9][0-9]:") {print} \
>                                     else if ($0 ~ "^[0-9][0-9]:") {p=0}}'
