分享请问：Jboss操作anywhere数据库时经常偶尔会出现SybConnectionDeadException，高分相送
最近，我们的系统随着用户数的追加,很不稳定。系统采用Jboss3.2.2+ASA数据库的J2EE架构，经常会在操作数据库时候 出现“JZ006: 捕获到 IO 例外:com.sybase.jdbc2.jdbc.SybConnectionDeadException: JZ0C0: 连接已关闭。”请教各位高手，分不够再加

this is something related to sybase. have u tried
to use mysql or oracle since the first time
immigration task takes no more than 2 days and
the second time might take only some hours after
you get the experience. btw you should post more
detail on this. Sounds like with the load that
there is some check for the connection to see if
it is null or similar type of code, and when it
gets here maybe the connection still exists then
later it is getting closed - not really sure
unless we have an idea of what you are doing in
the code.
i only find three msgs in google concerning
SybConnectionDeadException.. and all of them
have no solution. imo try mysql or oracle instead
of sybase as u r using the strong jdbc2..
remember sybase might extinct some day :)
