在盯着 Tomcat 时,我收到以下错误:

我之前在 Server.xml 中使用了相同的 dB 配置,并且 Tomcat 工作正常,但是自从我更改服务器并安装新副本后的最后两天,它抛出了这个错误。
server.xml 中定义的 GlobalNamingResources 如下:
<GlobalNamingResources>
<Resource name="jdbc/abcdOracle" auth="Container"
type="javax.sql.DataSource"
maxActive="100" initialSize="5" maxWait="2000"
username="xxxxxx" password="xxxxxx"
driverClassName="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@xxxxxx.xxxxxx.net:1523:ABCDE"
validationQuery="select sysdate from dual"
validationInterval="30000"
testWhileIdle="true" testOnBorrow="true" testOnReturn="false"
removeAbandoned="true" logAbandoned="true"
removeAbandonedTimeout="60" />
</GlobalNamingResources>
任何人都有任何提示如何解决这个问题。谢谢。
