Could not store secondary backup of session #157

GoogleCodeExporter commented 9 years ago 
  Thank u for u interested with the issuse.

 i use mms in this environment：msm-1.6.3,tc7-1.6.3,spymemcached2.7.3 and kyro 1.6.3

 When i visit my web site ,i got this log output:

INFO: Could not store secondary backup of session 
1B7D569C36DB1D7CE5161B9A49870BA6-n1
java.lang.IllegalArgumentException: No node found for key 
bak:1B7D569C36DB1D7CE5161B9A49870BA6-n1 (nodeId: null, known nodeIds: [n1, n2])

 And here is the useful content in my context.xml:

  <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"  
    memcachedNodes="n1:51.123.34.5:11211 n2:51.123.34.6:11211" 
    failoverNodes="n2"
    sticky="false"         
    sessionBackupAsync="false"  
    requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" 
    lockingMode="uriPattern:/path1|/path2"
    transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"     
    />     

how to solve? thanks!

This happens because you're using failoverNodes with sticky="false", which does 
not make sense. FailoverNodes are only useful for sticky sessions. Once you 
remove the failoverNodes configuration the mentioned log messages should be 
gone.

I'm  not set failoverNodes:
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
    memcachedNodes="nd47:192.168.29.47:11211,nd48:192.168.29.48:11211"
    sticky="false"
    sessionBackupAsync="false"
    lockingMode="auto"
    requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"
    transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"
    />
but ,it still happens,so any idea with this problem?

Does this happen always, or only sometimes? I looked at the code and verified 
some test cases, and I'd say this should only happen if nd48 is *not* 
available. If it happens in your case even if nd48 is available please provide 
a test case or a sample app that allows me to reproduce this issue.

Also it would help if you'd provide the full stack trace.

My architecture is:
            LVS(192.168.29.100 it's ok,when I test from the VIP,its on machine 192.168.29.47) 
                                                           /             \
                                   http(192.168.29.47:80)  http(192.168.29.48:80)
                                                       /           \ /     \
         Tomcat1(ajp://192.168.29.47:8109:jvm1) Tomcat2(ajp://192.168.29.48:8109:jvm4)  
=====================================================
I use apache mod_proxy as a balancer for tomcat1(jvm1)and tomcat2(jvm4)
here is the configuration:
=====================================================
<Proxy balancer://is-cluster/>
BalancerMember ajp://192.168.29.47:8109/ loadfactor=1 route=jvm1
BalancerMember ajp://192.168.29.48:8109/ loadfactor=1 route=jvm4
ProxySet lbmethod=bytraffic
</Proxy>
ProxyPass / balancer://is-cluster/ stickysession=JSESSIONID|jsessionid
=====================================================
I use ie explorer to access 192.168.29.100:80 , then apache(I dont know on 
which one) refer to jvm4(29.48:8109), then I success to login,and then  I 
reboot the machine(29.48), I got the error,can you unstand what i say ,my 
english is soso. :)

Not sure what's happening, but an issue might be that non-sticky sessions 
(sticky=false) are used in combination with a jvmRoute / with stickyness in 
apache.

Can you run apache without stickyness (and remove jvmRoute from tomcat config) 
and see if this changes the situation?

When I use sticky in memcached and set failoverNodes,I did not see the error 
again:
WARNING: Found no validity info for session id 
AEBD1FE6A416C82B304DF13A50CF9349-nd47.jvm1
but when I do the same things ,I got an apache 503 error.
 When I run apache without stickyness (and remove jvmRoute from tomcat config),I login the app ,and click any link ,and I soon be refer to the login page ,and login again!

Can you please activate debug logging according to 
https://code.google.com/p/memcached-session-manager/wiki/SetupAndConfiguration#C
onfigure_logging and send the output? Also post the configuration used for the 
test.
