1. 背景说明
本文承接Oracle Solaris 10图文安装。
在该文的章节8处，说到操作系统安装完后，默认是64位的，后边安装完gdb后运行会报错（详见“Oracle Solaris 10图文安装”）。
那是不是切换到32位模式下就可以运行了？现在验证下看看。
2. gdb相关包
本文开头处下载或者百度云。

3. gdb安装
3.1 上传资源
将资源上传到服务器上后，使用root用户开始安装。
3.2 解压

3.3 安装
最好按照下边的顺序安装。输出略。
pkgadd -d expat-2.0.1-sol10-x86-local
pkgadd -d gdb-6.8-sol10-x86-local
pkgadd -d libiconv-1.14-sol10-x86-local
pkgadd -d libintl-3.4.0-sol10-x86-local
pkgadd -d ncurses-5.7-sol10-x86-local
pkgadd -d gcc-3.4.6-sol10-x86-local
3.4 环境变量
有自己的.profile文件的话就改自己的，没有就改/etc/profile。
生效依次是.profile（有的话）-----> /etc/profile（没有.profile的话）。
我的root用户有自己的.profile文件，所以就改这个了。
[root@oracle:/]# cat .profile
alias ll='ls -l'
PS1='[\u@\h:$PWD]# '
export PS1
PATH=/usr/sbin:/usr/bin
export PATH
在以PATH开头一行改为PATH=/usr/sbin:/usr/bin:/usr/sfw/bin:/usr/local/bin。
在结尾再次追加
LD_LIBRARY_PATH=/usr/sfw/lib
export LD_LIBRARY_PATH
最终如下：
[root@oracle:/]# cat .profile
alias ll='ls -l'
PS1='[\u@\h:$PWD]# '
export PS1
PATH=/usr/sbin:/usr/bin:/usr/sfw/bin:/usr/local/bin
export PATH
LD_LIBRARY_PATH=/usr/sfw/lib
export LD_LIBRARY_PATH
[root@oracle:/]# source .profile
[root@oracle:/]# which gdb
/usr/local/bin/gdb
4. 位数确认
确保在32位下运行。
[root@oracle:/]# isainfo -v
32-bit i386 applications
avx xsave pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp cx16 sse3 sse2
sse fxsr mmx cmov sep cx8 tsc fpu bmi1 f16c fma rdrand
5. 验证可用性
用Oracle来验证是否可行，与之前的64位下Oracle用gdb调试出问题做对比。
需要安装Oracle 32位的版本，详见Solaris 10上Oracle 10g安装步骤图解。
session 1：
SQL> select b.spid from v$session a,v$process b where a.sid=(select sid from v$mystat where rownum=1) and a.paddr=b.addr;
