經過二天的折騰﹐才把SAP R/3 46C 安裝在redhat as2.1上,拿出來和各位SAP basis分享一下 First, you should get all of the right source. this is the most important things.
Second: Don’t install Oracle database first, ths sap installation process will prompt you to install DB. And all the group and user id will be created by it. When the process prompt you ,use that id(ie.oraprd) to install oracle database in a separate window, go back to continue after the installation of DB.
一. 硬件要求:
PC Server , with >= 1CPU, >=512MB, >=30GB
二. 分区方案
/: 5GB
swap: 2.5GB (>= 2GB)
/oracle: >= 12.5GB
三. 安装光盘
SAP Kernel CD
Export CD 4/4
DB for sap installation
Oracle 8.1.7 or Oracle 8.1.6 for Linux
四. 配置参数设定
cd /proc/sys/kernel
echo 512000000 > shmmax
echo 512 320000 100 1024 > sem
可以把以上信息写入到启动文件中
echo export LD_LIBRARY_PATH=/oracle/PRD/817_32/lib:/sapmnt/PRD/exe >>/etc/profile
vi /etc/services
预留3200, 3600, 4800端口号给SAP用
五. 软件包的选择
1. During RHEL Installation
Development Tool ( Including gcc, make, binutils 等)
Telnet Server ( telnet-server, ftp-server, rsh-server)
Pdksh (K Shell)
不要安装: Apache Server(WEB Server), OpenLDAP
2. During Oracle Installation
Default ,
Customerize Install, not create database.
Enterprise Server
安装前要确认unset LANG
用oraprd用户安装, 该用户的SHELL尽量用KSH
六. 主要步骤
1. SAP安装目录设为/oracle/sapinstall
2. SAP安装过程出现的任何中断是可以用安装指令在中断位置继续执行的
3. 需要事先准备好的目录: (架设SAP系统名为PRD) /usr/sap/trans, /usr/sap/PRD, /oracle/PRD/saparch, /oracle/PRD/sapdata1, /oracle/PRD/sapdata2, /oracle/PRD/sapdata3, /oracle/PRD/sapdata4, /oracle/PRD/sapdata5, /oracle/PRD/sapdata6, /oracle/PRD/sapreorg, /oracle/805_32, /oracle/PRD/817_32, /sapmnt, /sapmnt/PRD
4. mkdir /oracle/sapinstall
cd /oracle/sapinstall
mount /dev/cdrom /sapcd 插入Kernel CD
/sapcd/UNIX/INSTTOOL.SH
./R3SETUP –f CENTRAL.R3S
5. 安装过程中用default值, 除了:
DB system ID: PRD
Character set used by the database: WE8DEC
Version of Oracle DB software: 8.1.7
(3) No LDAP Support
(1) Database Instance on file system.
(1) Yes Extract (Extract the SAP system software archives)
七. 异常处理
由于Oracle 不是在SAP安装时安装的,而是在SAP安装到一定阶段后中断跳出后用oraprd用户安装的, 所以相应的要在/oracle/sapinstall目录下vi DATABASE.R3S, 把其中的STATUS=ERROR改成STATUS=OK, 继续运行SAP安装命令直到出现/R3SETUP finished , 这时候, 开始安装Oracle, 待Oracle 安装完毕后再继续安装SAP
八. 相关指令
mount –t iso9660 –r –o map=off /dev/cdrom /SAPCD
mount /dev/cdrom /sapcd
unset LANG
九. 數據庫安裝升級
從8170升級到8174,需要安裝oracle patch
p2376472_8174_LINUX.zip.

十．數據庫錯誤﹕
1. 在上需要安裝以下補丁:( resole this problem: Create Database failed errorcode = 3113)
glibc-2.1.3-stubs.tar.gz

2.system indicate that you should create DBMS_STANDARD package before run PL/SQL( execute “catproc.sql”)
3.if you encounter below problem, you can try to do this
2 steps:
ERROR: ORA-03113: end-of-file on communication channel
1>ipcs
2>ipcrm remove the oracle shm and sem memory
