最近一直在进行ORACLE 10g和PRO*C的学习。
其中遇到了不少的问题:
现列于此,已备他用。

[注:我的linux版本是RHEL 5,Oracle版本是10g]

1、在ORACLE 10g 安装准备的过程中:缺少libXp.so.6依赖
上网搜过不少文章,但是都不是很好的解决
我自己摸索出一个解决方法:
在RHEL5的安装盘中找到libXp-1.0.0-8.i386.rpm,进行安装后,便可解决。

2、在ORACLE 10g 安装过程中Xlib: connection to ":0.0" refused by server

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
Error: Can't open display: :0.0

以root用户登陆,在shell中运行
[root@brady ~]# xhost local:oracle
non-network local connections being added to access control list
然后oracle身份就可以运行X程序了。

man xhost中有这样一段
A complete name has the syntax ‘‘family:name’’ where the families are as follows:
inet Internet host (IPv4)
inet6 Internet host (IPv6)
dnet DECnet host
nis Secure RPC network name
krb Kerberos V5 principal
local contains only one name, the empty string
si Server Interpreted

其中local那个是用来解决同一台机器的不同用户访问X的问题的。

3.proc: error while loading shared libraries: libclntsh.so.10.1:
cannot open shared object file: No such file or directory
解决方法:
在/etc/profile中添加
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib:/usr/local/lib;
export LD_LIBRARY_PATH
然后可以用source /etc/profile 生效一下

4、PCC-S-02201错误

在用proc进行编译的时候(proc iname=test.pc) 出错
错误信息有很多:
PCC-S-02201, Encountered the symbol "<eof>;" when expecting one of the following....
发生 PCC-S-02201 错误时有两种解决办法:
1)升级编译器
2)修改$ORACLE_HOME/precomp/admin/pcscfg.cfg

  设置 parse=none

sys_include=(/app/oracle/product/db1/precomp/public,/usr/include,/usr/lib/gcc-lib/x86_64-redhat-linux/3.2.3/include,/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.3/include,/usr/lib/gcc/x86_64-redhat-linux/4.1.1/include,/usr/lib64/gcc/x86_64-suse-linux/4.1.0/include)
ltype
=short
define
=__x86_64__

更正后的命令:proc iname=test.pc parse=none
结果生成test.c文件

5、error: sqlca.h: No such file or directory

执行gcc -o test test.c时:
test.c:152:19: error: sqlca.h: No such file or directory
sqlca.h在$ORACLE_HOME/precomp/public/下
更正后的命令:gcc -o test test.c -I $ORACLE_HOME/precomp/public

6、undefined reference to `sqlcxt'

执行5中的命令时出现错误如下:
test.c:(.text+0x5e5): undefined reference to `sqlcxt'
需要用到$ORACLE_HOME/lib/libclntsh.so

故需加上 -L $ORACLE_HOME/lib -l clntsh
更正后的命令为:
gcc -o test test.c -I /home/oracle/oracle/product/10.2.0/db_1/precomp/public -L $ORACLE_HOME/lib -l clntsh
OK!至此编译成功!

但是这样写太麻烦

7、error while loading shared libraries: $ORACLE_HOME/lib/libnnz10.so:
cannot restore segment prot after reloc: Permission denied

执行程序(./test)时提示错误:
error while loading shared libraries: $ORACLE_HOME/lib/libnnz10.so:
cannot restore segment prot after reloc: Permission denied

Topic:
Some Linux distributions with SELinux enabled may prevent IDL from running under the default security context. This TechTip is a workaround for CR#41937

Discussion:
Newer Linux distributions have enabled new kernel security extensions from the SELinux project at the NSA. These extensions allow finer-grained control over system security. However, SELinux also changes some default system behaviors, such as shared library loading, that can be problematic to third party programs.If you receive the error message "cannot restore segment prot after reloc: Permission denied" when launching IDL, then your SELinux configuration is preventing IDL from launching.

To rectify this issue, you can either:
(1)Change the default security context for IDL by issuing the command:
chcon -t texrel_shlib_t /usr/local/rsi/idl_6.1/bin/bin.linux.x86/*.so

(2)Disabling SELinux altogether by setting the line
SELINUX=disabled
in your /etc/sysconfig/selinux file.

我使用的解决办法:chcon -t texrel_shlib_t $ORACLE_HOME/lib/*.so
