使用C++使用多线程建立的程序，在linux后台运行，运行过程中频繁出现ORA-01013错误。出现后还可以继续运行。在运行一段时间后（不是一个确定的时间）然后出现ORA-21500错误。程序进程自动断开结束掉。
请教原因。
------解决方案--------------------
ORA-01013 user requested cancel of current operation
Cause: The user interrupted an Oracle operation by entering CTRL-C, Control-C, or another canceling operation. This forces the current operation to end. This is an informational message only.
Action: Continue with the next operation.
ORA-21500 internal error code, arguments: [string], [string], [string], [string], [string], [string], [string], [string]
Cause: This is the generic error number for the OCI environment (client-side) internal errors. This indicates that the OCI environment has encountered an exceptional condition
莫非是你的OCI参数传错了？
