OERR: ORA-4031 "unable to allocate %s bytes of shared memory ("%s","%s","%s")" (文档 ID 4031.1)

APPLIES TO:

Oracle Database - Enterprise Edition - Version 9.2.0.1 to 11.2.0.1 [Release 9.2 to 11.2]
Information in this document applies to any platform.

PURPOSE

This article discusses the internal error "ORA-4031", what it means and possible actions. The information here is only applicable to the versions listed and is provided only for guidance.

SCOPE

This note is intended for general audience as initial starting point for beginning diagnosis of ORA-4031.

DETAILS



Error: ORA 4031
Text: unable to allocate %s bytes of shared memory (%s,%s,%s)
-------------------------------------------------------------------------------
Cause: More shared memory is needed than was allocated in the shared
pool.
Action: If the shared pool is out of memory, either use the
DBMS_SHARED_POOL package to pin large packages,
reduce your use of shared memory, or increase the amount of
available shared memory by increasing the value of the
initialization parameters SHARED_POOL_RESERVED_SIZE and 
SHARED_POOL_SIZE.
If the large pool is out of memory, increase the initialization
parameter LARGE_POOL_SIZE.


Missed size request signified by %s bytes 

Arguments within parenthesis ("%s","%s","%s"):

First argument: SGA pool area such as Shared pool, Large pool, Java pool, Streams pool

Second argument: Code running at the time space request was made

Third and Fourth argument: Memory allocations being requested

  • 在Android应用中使用Clean架构 赤耳A狼
    自从开始开发安卓应用，我一直感觉我可以做得更好。我看过不少烂代码，其中当然有我写的。安卓系统的复杂性加上烂代码势必酿成灾祸，所以从错误中成长就很重要。我Google了如何更好地开发应用，发现了这个叫做Clean架构的东西。于是我尝试将它应用于安卓开发，根据我在类似项目中的经验做了一些改善，写出了这篇我觉得较为实用、值得分享的文章。我会在这篇文章中手把手教你在Android应用中使用Clean架构。

  • 【Java范型七】范型消除 bit1129 java
    范型是Java1.5引入的语言特性，它是编译时的一个语法现象，也就是说，对于一个类，不管是范型类还是非范型类，编译得到的字节码是一样的，差别仅在于通过范型这种语法来进行编译时的类型检查，在运行时是没有范型或者类型参数这个说法的。 范型跟反射刚好相反，反射是一种运行时行为，所以编译时不能访问的变量或者方法(比如private)，在运行时通过反射是可以访问的，也就是说，可见性也是一种编译时的行为，在
