原因：
是Oracle的一个bug

Check Metalink note:
ORA-27300 ORA-27301 ORA-27302 in alert log. Cannot connect to database-371074.1

Note:371074.1

To implement the solution, please execute the following steps:

Tune the application running on the 32-bit environment so that it will not consume greater than
2.7GB of virtual memory when the '/3GB' switch is set in the 'boot.ini' file.
In the case of Oracle encountering the OS resource issue, the options are:

1) Reduce the amount of SGA needed to be allocated for the database.
2) Limit the number of dedicated connections to the database and the amount of memory each user
process will consume.
3) Change from dedicated connections to multi-threaded server (MTS) connections as MTS only
uses a fraction of the amount of memory allocated to each user process when initial connection to
the database is established.

在命令行打开c:\boot.ini 文件
在文件的末尾加上 “/3GB”

如:c:\boot.ini文件内容：
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows Server 2003 Enterprise x64 Edition" /noexecute=optout /fastdetect /3GB
