错误

ORA-00054

resource

资源正忙，要求指定NOWAIT

ORA-00600

internal
error code,arguments:[num],[?],[?],[?],[?]

产生原因：这种错误通常为ORACLE的内部错误，只对OSS和ORACLE开发有用。ORA-600的错误经常伴随跟踪文件的状态转储（系统状态和进程状态），系统状态存储将包括ORACLE RDBMS持有的当前对象的信息，进程状态转储则将显示特殊进程持有的对象，当进程符合了某错误条件时，经常是由于一些信息取自它持有的一个块，如果我们知道这些错误进程持有的块，就容易跟踪问题的来源。

解决方法：一般来说出现这个错误我们本身是无法解决的，只有从提高系统本身各方面来解决这个内部问题，如增加硬件设备，调整系统性能，使用OPS（当然OPS从某种意义上说并不是一种好的解决方式）等。ORA-600错误的第一个变量用于标记代码中错误的位置（代码中的每个部分的第一变量都不一样），从第二个到第五个变量显示附加信息，告诉OSS代码在哪里出现了错误。

一个报错例子如下：

ORA-00600:
internal error code, arguments: [1237], [], [], [], [], [], [], []

相应的英文如下：

Cause:This
is a catchall(包罗万象的) internal error message for Oracle program exceptions.It
indicates that a process has met a low-level,unexpected condition.Various
causes of this message include:

Time-outs（超时）

File
corruption(文件太老)

Failed
data checks in memory（内存检索失败）

Hardware,memory,or

Service Layer

The service layer has within it a variety of
service related components which are associated with in memory related
activities in the SGA such as, for example : the management of Enqueues,
System Parameters, System state objects (these objects track the use of
structures in the SGA by Oracle server processes), etc.. In the main, this
layer provides support to allow process communication and provides support
for locking and the management of structures to support multiple user
processes connecting and interacting within the SGA.

Note : vos  - Virtual Operating System
provides features to support the functionality above.  As the name
suggests it provides base functionality in much the same way as is provided
by an Operating System.

Cache Layer

Where errors are generated in this area, it is
advisable to check whether the error is repeatable and whether the error is
perhaps associated with recovery or undo type operations; where this is the
case and the error is repeatable, this may suggest some kind of hardware or
physical issue with a data file, control file or log file. The Cache layer is
responsible for making the changes to the underlying files and well as
managing the related memory structures in the SGA.

Note : rcv indicates recovery. It is
important to remember that the Oracle cache layer is effectively going
through the same code paths as used by the recovery mechanism.

Transaction Layer

Primarily the transaction layer is involved with
maintaining structures associated with the management of transactions. 
As with the cache layer , problems encountered in this layer may indicate
some kind of issue at a physical level. Thus it is important to try and
repeat the same steps to see if the problem recurs.

Data Layer

The data layer is responsible for maintaining and
managing the data in the database tables and indexes. Issues in this area may
indicate some kind of physical issue at the object level and therefore, it is
important to try and isolate the object and then perform an anlayze on the
object to validate its structure.
