JBOSS 服务器日志显示错误 SESSIONINFO 添加空值
JBOSS server log showing error SESSIONINFO adding null values
我有 war 文件部署在 jboss-eap-6.3，JBPM 在 [=28= 上运行]-eap-6.4。我们正在使用在 JBPM 中处理的决策表（excel 表）。
我们将 RESTful webserive 与 ejb 和 java 一起使用。
为了执行规则，我们使用 drools-6.0.1.Final。
每当我有大约 4-5 个值的小请求时，它都会给出输出。
但是每当我收到大约超过 100 个值的响应时，我都会在 server.log 文件 jboss-eap-6.4:
中收到此错误

我试图在互联网上寻找解决方案，但没有成功。我尝试更改超时时间，增加线程池大小，增加 standalone.xml.If 中各处的线程大小有人可以给我一个想法或给我一些相关的文章，这将非常有帮助。
这似乎与 H2 DB 有关，而不直接与 JBoss 本身有关。
异常：
18:45:09,146 WARN [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (EJB default - 141) SQL Error: 50200, SQLState: HYT00 18:45:09,147 WARN [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (EJB default - 138) SQL Error: 50200, SQLState: HYT00 18:45:09,163 ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (EJB default - 141)
如社交 MSDN 中所述，问题可能与 SQL 服务器混合身份验证模式或 DNS 通信有关。
但特别是在您的情况下，以下几行表明该语句无法提交给 table "SESSIONINFO"，因此它抛出了超时异常：
Could not commit session: javax.persistence.PessimisticLockException: could not execute statement at
在使用 JBPM 时，h2 数据库的某处被配置为我们应用程序中的数据源 (standalone.xml)，因此当许多请求同时到来时，h2 数据库无法处理并给出 悲观锁异常
The solution was to add MVCC=true in the url which is mutliversion
concurrency control and you can read more about it.

我试图在互联网上寻找解决方案，但没有成功。我尝试更改超时时间，增加线程池大小，增加 standalone.xml.If 中各处的线程大小有人可以给我一个想法或给我一些相关的文章，这将非常有帮助。
这似乎与 H2 DB 有关，而不直接与 JBoss 本身有关。
异常：

如社交 MSDN 中所述，问题可能与 SQL 服务器混合身份验证模式或 DNS 通信有关。
但特别是在您的情况下，以下几行表明该语句无法提交给 table "SESSIONINFO"，因此它抛出了超时异常：
Could not commit session: javax.persistence.PessimisticLockException: could not execute statement at
在使用 JBPM 时，h2 数据库的某处被配置为我们应用程序中的数据源 (standalone.xml)，因此当许多请求同时到来时，h2 数据库无法处理并给出 悲观锁异常
The solution was to add MVCC=true in the url which is mutliversion concurrency control and you can read more about it.
