ORA-12528:
TNS:listener: all appropriate instances are blocking new connections
ORA-12528问题是因为监听中的服务使用了动态服务,实例虽然启动,但没有注册到监听。实例是通过PMON进程注册到监听上的,而PMON进程需要在MOUNT状态下才会启动。所以造成了上面的错误。
解决这个问题,有三种方法:
1、把监听设置为静态;
2、在tnsnames.ora中追加(UR=A);
3、重新启动服务;
方法1、通过修改listener.ora的参数,把listener.ora动态注册设置为静态注册,然后重新启动监听
# listener.ora Network Configuration File: $ORACLE_HOME\network\admin\listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = [IP])(PORT = 1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = [DBNAME])
(ORACLE_HOME = [$ORACLE_HOME])
(SID_NAME = [SID])
)
)
静态注册的风险:如果在instance运行中,lisener重新启动,就找不到instance了。静态注册需要先启动lisener,再启动instance。且静态模式下,lisener status显示的是unknown
方法2、启动到nomount状态,通过修改tnsnames.ora的参数
# tnsnames.ora Network Configuration File: $ORACLE_HOME\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
SYK =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = [IP])(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SYK)
(UR=A)
)
)
然后连接上数据库
SQL>alter database mount;
SQL>alter database open;
方法3、重启ORACLE或者重启ORACLE服务
在oracle帐户下依序执行如下命令:
sqlplus / as sysdba;//在其它帐户(如root)下执行可能会报错(ORA-01031)因为这些帐户没有在dba组中
shutdown immediate;
startup;

oracle实例名: error while loading shared libraries: libskgxp10.so: cannot open shared object file: No such file or directory
是环境变量LD_LIBRARY_PATH的问题。
在10g以后,一般情况下环境变量中没有必要设置LD_LIBRARY_PATH,但是一旦将ORACLE_HOME迁移到其他目录,则环境变量中还需要添加这个变量。
Linux和Unix支持TAR方式迁移ORACLE_HOME,如果有需要将ORACLE_HOME放到其他路径下,那么一般都会使用tar的方式将整个路径拷贝到目标目录。
但是迁移后,如果直接尝试sqlplus启动,可能报错:
[orat3@hpserver2 ~]$ sqlplus / as sysdba
sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory
而设置LD_LIBRARY_PATH后,问题解决:
[orat3@hpserver2 ~]$ export LD_LIBRARY_PATH=$ORACLE_HOME/lib
[orat3@hpserver2 ~]$ sqlplus / as sysdba

错误的表相虽然不同,但是解决方法是相同的。

ORA-00204:ORA-00202:ORA-27091
Oracle数据库启动报如下错误:
ORA-00204: error in reading (block 3, # blocks 8) of controlfile
ORA-00202: controlfile:‘/app/oracle/OraHome1/database/datafiles/control1.ctl‘
ORA-27091: skgfqio: unable to queue I/O
SVR4 Error: 25: Inappropriate ioctl for device
Additional information: 3
说明control1.ctl文件有问题啦!
想把这个文件mv到别的目录做个备份,但I/O error,果然是坏了!
一般控制文件有3个,除非3个都坏了,不然可以用好的替换坏的:
rm control1.ctl
cp control2.ctl control1.ctl
再重新启动Oracle就OK啦!

ORA-01031: insufficient privileges
出错的场景:
(1)用sqlplus "/ as sysdba"登陆
(2)登陆成功后在执行相关操作
第二种情况没什么说的,没权限,赋经即可
第一情况的解决办法:
要sqlplus "/ as sysdba"进行登陆必须满足如下条件:
(1)linux/unix下有环境变量ORACLE_SID,windows不要求
(2)配置环境变量ORACLE_HOME
(3)linux/unix下$ORACLE_HOME/bin/oracle文件在u,g下有s权限(让非oracle用户可以拥有相当于oracle帐户 的,赋值方法chmod u+s,g+s $ORACLE_HOME/bin/oracle)
(4)执行此操作的用户必须在dba用户组中
Tips:
Linux/unix下非oracle用户下不建议使用sqlplus "/ as sysdba"登陆,建议使用sqlplus /nolog后使用conn 命令或sqlplus username[@sid]登陆
