Linux下共享库问题导致无法启动SQLPLUS的问题解决

来源：互联网发布：golang syscall详解编辑：程序博客网时间：2024/05/18 20:52

现象:

sqlplus /nolog
sqlplus: error while loading shared libraries: /u01/app/oracle/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1: cannot restore segment prot after reloc: Permission denied

解决办法:

这个问题是由于SELINUX引起的.

1. 编辑/etc/sysconfig/selinux配置文件, 把SELINUX=enforcing 改为 SELINUX=disabled.

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#       enforcing - SELinux security policy is enforced.
#       permissive - SELinux prints warnings instead of enforcing.
#       disabled - SELinux is fully disabled.

#SELINUX=enforcing
SELINUX=disabled

# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted

2. 使用命令chcon 改变文件或者目录的SELinux属性, 语法chcon -t texrel_shlib_t 库名字

[oracle@null-00137223684e ~]$ sqlplus /nolog
sqlplus: error while loading shared libraries: /u01/app/oracle/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1: cannot restore segment prot after reloc: Permission denied

[oracle@null-00137223684e ~]$ chcon -t texrel_shlib_t /u01/app/oracle/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1

[oracle@null-00137223684e ~]$ sqlplus /nolog

SQL*Plus: Release 11.2.0.1.0 Production on Tue Sep 20 14:31:21 2011

SQL>

如果运行过程中发现其它的库文件也报类似的错误, 可以使用同样的方法来解决.
