Catalina Shutdown relies on localhost causing problems in a Clustered Solaris environment
Summary: Catalina Shutdown relies on localhost causing problems
in a Clustered Solaris environment
Product: Tomcat 4
Version: 4.0.1 Final
Platform: Sun
OS/Version: Solaris
Status: NEW
Severity: Enhancement
Priority: Other
Component: Catalina
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: clwatson@Celestica.com
CC: clwatson@Celestica.com
I am using Tomcat in a clustered Sun E10000 (E10K). I run an Apache/Tomcat
instance on each logical server with one or more logical servers running on a
given node on the E10K. As a result, a node will be associated with a number of
IP addresses, with a subset of those IPs associated with a logical server. I
need to be able to bind the Tomcat Startup / Shutdown with a given IP or set of
IPs. I was able to exploit an undocumented 'inet' parameter in the earlier
Tomcat 3 code and hack org.apache.tomcat.task.StopTomcat.java to achieve this,
but the structure is completely different for Catalina.
The modifications to Catalina for this enhancement would include:
---------------
1) Add an 'inet' (or equivalent) parameter to the Server tag in server.xml
<Server inet="myserver.com" port="8005" shutdown="SHUTDOWN" debug="0">
2) Change org.apache.catalina.core.StandardServer.java line 276-8
serverSocket =
new ServerSocket(port, 1,
InetAddress.getByName("127.0.0.1"));
to incorporate the inet address defined in the Server tag from server.xml and
use "127.0.0.1" as the default value if it is not defined.
3) Change org.apache.catalina.startup.Catalina.java line 826
Socket socket = new Socket("127.0.0.1", server.getPort());
to incorporate the inet address define in the Server tag from server.xml and
use "127.0.0.1" as the default value if it is not defined.
---------
Ideally, I would like to be able to bind a set of IPs to Tomcat 4, but the
Socket I/O implementation in java lacks the accept() method available in C to
do this. Since I use an Apache front end, all communication to Catalina is over
one IP anyway.
