本文介绍如何查看 ODP 上所有网络连接的内部属性状态。
命令介绍
您可通过 SHOW PROXYNET CONNECTION 语句查看 ODP 上所有网络连接的内部属性状态。
SHOW PROXYNET CONNECTION [thread_id [LIMIT xx]]
参数说明：
thread_id：线程 ID，不指定 thread_id 时，展示 ODP 上所有网络连接的内部属性状态；指定 thread_id 时，仅展示指定 thread 上的连接状态。LIMIT xx：支持指定 LIMIT [offset,] rows 和 LIMIT rows OFFSET offset 参数，格式与 MySQL 完全兼容。当 rows == -1 时，展示全部行。
语句执行后输出如下：
*************************** 1. row ***************************
thread_id: 0
connect_id: 1
socket_fd: 4
type: inner connected
src_ip: XXX.XXX.XXX.XXX
src_port: 43051
dst_ip: XXX.XXX.XXX.XXX
dst_port: 13203
virtual_ip: *Not IP address [0]*
virtual_port: 0
bind_style: any
read_enabled: 1
read_nbytes: 9223372036854775807
read_ndone: 0
write_enabled: 0
write_nbyte: 0
write_ndone: 0
alive_time(sec): 2864
activity_timeout_in(sec): 0
inactivity_timeout_in(sec): 28800
timeout_close_in(sec): 28791
last_error_no: 0
shutdown: 0
