检查/tmp/.oracle 和 /var/tmp/.oracle 这2个文件夹的属组是否正确，如果不正确，改为 chown -R grid:oinstall
2.在保证上面2个目录权限正确的情况下，连接报错ORA-12537: TNS:connection closed

tnsping正常，监听状态正常，但是连接报错ora-12537。
检查$ORACLE_HOME/bin/oracle的权限应该为6751
[oracle@ora11g admin]$ ls -la $ORACLE_HOME/bin/oracle -rwxr-s--x 1 oracle asmadmin 232399473 Nov 11 2013 /u01/app/oracle/product/11.2.0/db_1/bin/oracle [oracle@ora11g admin]$ chmod 6751 $ORACLE_HOME/bin/oracle [oracle@ora11g admin]$ ls -la $ORACLE_HOME/bin/oracle -rwsr-s--x 1 oracle asmadmin 232399473 Nov 11 2013 /u01/app/oracle/product/11.2.0/db_1/bin/oracle
官方的解释：
Applies to:
Oracle Net Services - Version: 8.1.7.0 to 11.2.0.1 - Release: 8.1.7 to 11.2
Generic UNIX
Checked for relevance on 30-Apr-2010
Symptoms
Connection to the database server fails with ORA-12546 or ORA-12537
Local connections working fine but the connection via listener fails with ORA-12537 or ORA-12547
Cause
Permissions on oracle binary ( $ORACLE_HOME/bin/oracle ) are not set correctly.
Solution
The OS level error message in the listener log "Linux Error: 13: Permission denied" indicates that the listener was not able to hand off the connection to oracle processes or not able to spawn a new dedicated user process because of lack of permission at the OS level. To resolve the error -
1. Check and correct the permission on /var/tmp/.oracle directory. Permissions on this directory should be 777 with sticky bit set.
# chmod 01777 /var/tmp/.oracle
2. Check and correct permissions on $ORACLE_HOME/bin/oracle binary and make sure that it is set to 6751.
$ chmod 6751 $ORACLE_HOME/bin/oracle
