Bug ID 469742: Intermittent instances of SQL monitor database connections hanging

Last Modified: Nov 22, 2021

Affected Product(s):
BIG-IP LTM(all modules)

Known Affected Versions:

Opened: Jun 30, 2014

Severity: 3-Major


You might intermittently encounter instances of SQL monitor database connections hanging.


Connections might hang intermittently. Note: Because this release contains no SQL monitors commands to check the status of outstanding pings and cached connections, it might be difficult to debug the issues.


This occurs with monitors that access SQL databases, such as Oracle monitors.



Fix Information


Behavior Change

A new command has been added to help diagnose the state of the SQL monitors: -- /usr/share/monitors/DB_monitor cmd status [RD] [debug] -- RD: optional, the route domain for the desired Java daemon (each route domain gets a separate daemon) -- debug: optional, do debug logging Examples: -- /usr/share/monitors/DB_monitor cmd status -- /usr/share/monitors/DB_monitor cmd status 0 -- /usr/share/monitors/DB_monitor cmd status 17 -- /usr/share/monitors/DB_monitor cmd status 9 debug
