Oracle 10g Forms Connection错误500

Question

我在Java控制台中有以下日志：

2017-Oct-28  17:45:31.733 WUT[setProperty()] Setting property WUC_GET_LOCAL_PROPERTY to syslib.JNIsharedstubs.dll
2017-Oct-28  17:45:31.733 WUT[getProperty()] Getting property WUC_GET_LOCAL_PROPERTY
Reconnecting (try 1 of 60)...
Reconnecting (try 2 of 60)...
Reconnecting (try 3 of 60)...
Reconnecting (try 1 of 5)...
Reconnecting (try 2 of 5)...
Reconnecting (try 3 of 5)...
Reconnecting (try 4 of 5)...
Reconnecting (try 5 of 5)...

正如您所看到的，我已经定义了属性networkRetries = 60，并且它使用该值进行初始重新连接。它似乎能够连接，然后连接显然已断开，它开始尝试再次重新连接值为5.

你能帮我解决这个问题吗？

进一步分析后......

我能够找到OC4J_BI_FORMS的application.log文件中记录的异常：

有人遇到同样的问题吗？
