做RMAN 的实验，备份的时候异常中断，返回错误：
ORA-00600: internal error code, arguments: [%s], [%s], [%s], [%s], [%s], [%s], [%s], [%s]
一个备份也能600错误，有点意外。 本打算重启Oracle的，shutdown abort 都执行不了，无耐把系统重启一下，在看看。 重启之后，在连，报了另外一个错误，不过还是600：
ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], []
600 是Oracle 内部的错误，一般出现600 都是比较棘手的，很可能是Oracle bug。在启动Listener的时候也报机器名的错误，觉得hosts文件有问题，在host文件里添加了一条：10.85.10.1 db1
[root@db1 ~]# more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost
10.85.10.1 db1
然后检查一下listener.ora 和 tnsnames.ora 文件：
LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = db1)(PORT = 1521))
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = db1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = db1)(PORT = 1521))
)
)
在启动，搞定了：
SQL> conn / as sysdba

SQL> startup
ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], []

只是一个测试环境，如果在生产库上出现600的错误，bug的可能就非常大了。 所以还是要慢慢积累经验。
