Kelven Yang 3a6f3b71e0 bug 10791: add data integrity check upon management server startup 2011-07-21 17:08:29 -07:00
alena 307741edcd 2 fixes for Agent Load Balancer: 
* when management server dies and notifies other management servers about this, the running management server has to cleanup host_transfer records belonging to the died management server
* issue agent load balancing task only when agent load (number of connected agents in the system) exceeds "agent.load.threshold" - 70% by default

Kelven Yang 72cbd65db2 bug 10668: add DB upgrade scripts for 2.2.7 to 2.2.8 upgrade 2011-07-08 18:12:13 -07:00
Alex Huang cfc25d01be bug 10501: This is really Kelven's bug but I'll fix it for him anyways. DAO code already have a way to extract the DB connection from a transaction that is stored in the TLS. There's no real reason for the DAO code to add special semantics to use a different DB connection. That can be done by simply switching the transaction before it even reached the dao code. Think about it. Why would anyone want to call one dao function, switch transaction, and then switch back. The right thing is for the caller to switch transaction, call a series of dao codes, and switch it back. That's the semantics I changed to. By doing this, it also eliminates the number of debug messages in this bug. 2011-07-01 11:03:12 -07:00

alena b2b4a63fd3 Some fixes to agent lb code: 
* Schedule agent LB as a TimerTask as it can take time for the management server to start; and it can accept rebalance requests only when it's up and running
* Removed Starting state from mshost as it's not being used anywhere
* Fixed the bug where requests weren't routed properly from the old host owner to the new one.
