Is there a way for the cache to stay up without timeout after crash in AppFabric Cache? -

-

first setup used testing purpose:

  • 3 virtual machines running following configuration:
    • ms windows 2008 server standard edition
    • latest version of appfabric cache
    • each 1 has local network share config file stored (i have added machines in each config)
    • the cache distributed not high availibility (we don't have enterprise version of windows)
    • each host configured lead, according documentation @ least 1 host should allowed crash.
    • each machine has website testing installed, , local cache configured
  • one linux machine used proxy (varnish used) distribute traffic testing purpose.

that's setup , on problem. scenario testing simulating 1 of servers crashing , bring in cluster. have problem both server crashing , bringing up. steps using test it:

  • direct traffic varnish on linux machine 1 server only.
  • log in make sure there in cache.
  • unplug network cable 1 of other servers (simulates server crashing)

now cache timeout , service error. want application still on servers didn't crash, , take time cache come on remaining servers. how should be? plugging network cable in , starting host cause similar problem.

so question if have missed something? see happen if 1 server crashes cache should still remaing upp since majority of leads still up, , starting crashed server again should bring gracefully cluster without causing problems on other hosts. might no how works?

i ran through similar test scenario few months ago had test client generating load on 3 lead-server cluster variety of puts, gets, , removes. rebooted 1 of servers multiple times while load test running , cache stayed online. if remember correctly, there limited number errors server rebooted, overall cache appeared remain healthy.

i'm not sure why you're not seeing similar results, try removing varnish proxy test , see if helps.

i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt
