环境
1.aix6100-05
2.oracle10.2 补丁10.2.4
3.SAP ECC6.0
安装过程按照教程进行，其中过程中ORACLE安装出错概率很大。
错误1.
Symptom ORA-12546: TNS:permission denied（SAP安装到CRTEATE
DATABASE的时候查LOG）
启动 #lsnrctl start
或dbca重新创建数据库的时候出现如上错误提示
按照NOTES：Note 722966 - Composite SAP Note:
ORA-12546
Symptom ORA-12546: TNS:permission
denied
Other terms TNS-12546 12546
Reason and Prerequisites
An ORA-12546 error may occur due to various authorization
problems that can occur while you are building a database
connection using Oracle Net.
Refer to note 562403 for more information about Oracle Net.
The error may have the following causes:
1. UNIX: Authorizations for the
socket files are not correct.
2. UNIX: Authorizations for the
Oracle executable are not correct.
3. You are not allowed to use a port
in listener.ora.
4. Resource problems may occur.
5. TCP.INVITED_NODES restricts the
connection.
6. WINDOWS: Installation on
EM64T/X64
Solution
1. To establish an Oracle Net
connection, socket files are placed in the /var/tmp/.oracle or the
/tmp/.oracle directory. If the system cannot access the sockets
correctly, the connection may fail with an ORA-12546 error message.
Refer to note 396873 for more information.
2. Check, as described in note
583861, whether the authorizations were set correctly for the
Oracle executable.
3. The error can occur while you are
starting the listener if you have specified a port in the
listener.ora file that is outside of the range allowed by the
operating system. You should, therefore, ensure that you are not
using any port with a number lower than 1024 in the listener.ora
file. In addition, you should check the operating system
dependent-configuration of the valid ports.
Furthermore,
check whether the port cannot be used for any other reasons (for
example, because it is already assigned to another program). By
default, the Oracle Net environment uses port 1521 or 1527.
If
you require more information about your operating system, contact
your operating system partner.
4. If the error only occurs after the
database has already been running for a while, check, as described
in note 384839, whether there are resource bottlenecks.
5. ORA-12546 can also occur if
database access is restricted to certain hosts using the
TCP.INVITED_NODES Oracle net parameter, and you try to log on from
another host. Check whether this access restriction exists and
whether it is configured correctly in accordance with Note
186119.
6. The installation of Oracle on
EM64T/X64 is not currently supported. Attempts to log on to the
database may fail with ORA-12546. The
listener.log contains the
following entry:
32-bit Windows Error: 5: Input/output error
Therefore,
only install Oracle on supported platforms.
*************************************************************************************************
按照以上NOTES提示把/var/tmp/.oracle
和/tmp/.oracle 2个文件进行chown -R oracle filename.
就恢复正常,当然ORACLE安装中还有其它很多错误，都通过重装ORACLE恢复正常了。
二。
