weblogic无法创建连接池

今天下午开发说合同管理系统开发环境的weblogic一直启动不了:

如果正常启动日志大概如下：

####<2013-12-14 上午10时28分48秒 CST> <Info> <JDBC> <hsz-7880> <myserver> <Main Thread> <<WLS Kernel>> <> <BEA-001177> <Creating Connection Pool named conn_contract, URL = jdbc:sybase:Tds:10.17.192.123:5000/contract2011?charset=cp936, Properties = {user=sa, url=jdbc:sybase:Tds:10.17.192.123:5000/contract2011?charset=cp936, networkProtocol=Tds, portNumber=5000, userName=sa, databaseName=contract2011?charset=cp936, serverName=10.17.192.123}.>

但是weblogic卡着启动不了，

启动异常日志与正常启动日志相比，好像缺少了初始化连接池的过程,但是删除连接池后weblogic则可以正常启动，

所以基本上判断sybase数据库最大连接数不够，需要修改最大连接数;

登陆：
isql -Usa -Scmproce

1、查看最大连接数

sp_configure 'number of user connections'

结果如下：

Parameter Name Default Memory Used Config Value Run Value Unit Type

-------------- ------- ----------- ------------ --------- ----

number of user connections 25 2372 25 25 number dynamic

Sybase的数据库默认最大连接数为25，当连接数不够用的情况下，需要修改数据库配置。

2、修改为200

sp_configure 'number of user connections',200

----经验证，修改最大连接数后weglogic启动正常.
