Question

环境详情：操作系统RHEL 6.8 64位 IBM MobileFirst Platform Server版本 - 7.0.0.00.20160526-2153 Project WAR Version - 7.0.0.00.20161114-0240 应用程序版本 - 7.0.0.00.20160526-2153 IBM Websphere Liberty Verison - 8.5.5.4 Java - IBM JRE 1.7.0

在IBM Knowledge Center MobileFirst 7.0 Configure Farm之后创建了一个服务器场配置，其中包含jndiName =“ibm.worklight.admin.serverid”，farm_member_1和farm_member_2的唯一值。一开始，两个服务器都将这些显示在messages.log中：

[1/8/17 18:53:14:313 CST] 00000034 SystemErr R 1111  WorklightManagementPU-db2  INFO   [LargeThreadPool-thread-10] openjpa.Runtime - Starting OpenJPA 1.2.2

[1/8/17 18:53:14:315 CST] 00000034 SystemErr R 1113  WorklightManagementPU-db2  INFO   [LargeThreadPool-thread-10] openjpa.jdbc.JDBC - Using dictionary class "org.apache.openjpa.jdbc.sql.DB2Dictionary" (DB2/LINUXX8664 SQL10053 ,IBM Data Server Driver for JDBC and SQLJ 4.17.29).

[1/8/17 18:53:14:364 CST] 00000034 SystemErr R 1162  WorklightManagementPU-db2  INFO   [LargeThreadPool-thread-10] openjpa.Runtime - Though you are using optimistic transactions, OpenJPA is now beginning a datastore transaction because you have requested a lock on some data.

几乎每次将应用程序上传到运行时，服务器2（farm_member_2）都会无响应（Web控制台主页 - ＆gt;运行时 - >服务器场节点）。当发生这种情况时，服务器2正在更新所有资源，就像重新启动一样，从运行时加载所有应用程序和适配器。完成加载所有应用程序后，会再次显示这些错误：

[1/9/17 1:43:19:868 CST] 00000b05 com.ibm.worklight.admin.jmx.ManagementMXBeanImpl             I runtime01: server01///10.77.230.146: 2017-01-09T07:43:19.850Z: Transaction handler reset

[1/9/17 1:43:19:872 CST] 00000a86 SystemErr R 16601596  WorklightManagementPU-db2  INFO   [LargeThreadPool-thread-1589] openjpa.Runtime - Though you are using optimistic transactions, OpenJPA is now beginning a datastore transaction because you have requested a lock on some data.

[1/9/17 1:43:19:880 CST] 00000a86 SystemErr R 16601604  WorklightManagementPU-db2  INFO   [LargeThreadPool-thread-1589] openjpa.Runtime - Though you are using optimistic transactions, OpenJPA is now beginning a datastore transaction because you have requested a lock on some data.

这种配置是常见的吗？如果没有，关于如何避免这种想法？

Answer 1

这些是警告，可以安全地忽略。这些是由OpenJPA包记录的。

MobileFirst 7.0在服务器场模式下上传应用程序时，会收到“无响应”错误
