|
| registerTomcat | | public void registerTomcat(String host, int port, String unixDomain) throws IOException(Code) | | Register a tomcat instance
XXX make it more flexible
|
| setDump | | public void setDump(String dumpFile)(Code) | | Copy the scoreboard in a file for debugging
Will also log a lot of information about what's in the scoreboard.
|

|

|
| setHelp | | public void setHelp(boolean b)(Code) | | |
| setPort | | public void setPort(int port)(Code) | | Ajp13 port
|
| setReset | | public void setReset(boolean b)(Code) | | Set this to get the scoreboard reset.
The shm segment will be destroyed and a new one created,
with the provided size.
Requires "file" and "size".
|
| setSize | | public void setSize(int size)(Code) | | Size. Used only if the scoreboard is to be created.
|
| setUnixSocket | | public void setUnixSocket(String unixSocket)(Code) | | Unix socket where tomcat is listening.
Use it only if tomcat is on the same host, of course
|
| setUnregister | | public void setUnregister(boolean unregister)(Code) | | Set this option to mark the tomcat instance as
'down', so apache will no longer forward messages to it.
Note that requests with a session will still try this
host first.
This can be used to implement gracefull shutdown.
Host and port are still required, since they are used
to identify tomcat.
