1. 背景說明
本文承接Oracle Solaris 10圖文安裝。
在該文的章節8處，說到操作系統安裝完后，默認是64位的，后邊安裝完gdb后運行會報錯（詳見“Oracle Solaris 10圖文安裝”）。
那是不是切換到32位模式下就可以運行了？現在驗證下看看。
2. gdb相關包
本文開頭處下載或者百度雲。
百度雲地址：提取碼：yf71
（要積分的都是“流氓”😃）
3. gdb安裝
3.1 上傳資源
將資源上傳到服務器上后，使用root用戶開始安裝。
3.2 解壓

3.3 安裝
最好按照下邊的順序安裝。輸出略。
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 環境變量
有自己的.profile文件的話就改自己的，沒有就改/etc/profile。
生效依次是.profile（有的話）-----> /etc/profile（沒有.profile的話）。
我的root用戶有自己的.profile文件，所以就改這個了。
[root@oracle:/]# cat .profile
alias ll='ls -l'
PS1='[\u@\h:$PWD]# '
export PS1
PATH=/usr/sbin:/usr/bin
export PATH
在以PATH開頭一行改為PATH=/usr/sbin:/usr/bin:/usr/sfw/bin:/usr/local/bin。
在結尾再次追加
LD_LIBRARY_PATH=/usr/sfw/lib
export LD_LIBRARY_PATH
最終如下：
[root@oracle:/]# cat .profile
alias ll='ls -l'
PS1='[\u@\h:$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. 位數確認
確保在32位下運行。
[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. 驗證可用性
用Oracle來驗證是否可行，與之前的64位下Oracle用gdb調試出問題做對比。
需要安裝Oracle 32位的版本，詳見Solaris 10上Oracle 10g安裝步驟圖解。
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;
SPID

其他的終端，在OS（oracle用戶）下執行：
