一、 目的

SAP系统的数据库及组件升级，需要先升级kernel版本，目前加多宝SAP系统的kernel版本为7.00，计划升级到版本7.21。

二、 升级过程

1、 解决：DDIC_TYPELENG_INCONSISTENT的问题 打入note 1222907和note 1610716

运行SE38，执行程序RUT_NOTE_1610716 2、 停止SAP系统 su - prdadm stopsap

停止SAPOSCOL root用户

cd /usr/sap/PRD/SYS/exe/run ./saposcol -k Stop sapstartsrv

ps -ef|grep sapstartsrv kill -2 426216

Remove any IPC objects that still exist (this is required on UNIX only): su - prdadm

cleanipc 00 remove

3、 备份old kernel

/data/kernel/SAPCAR -cvf /data/kernel/sapexe.tar ./* 报错：SAPCAR: file './SIGNATURE.SMF'

Tiny210v2( S5PV210 )平台下:

利用uboot启动远程Kernel(TFTP)以及挂载远程ROOTFS(NFS)

0. 准备工作

1. 编译uboot

2. 将uboot写入SD卡

3. 编译kernel，设置其可以通过NFS挂载根文件系统

4. 开发环境安装TFTP服务器

5. 开发环境安装NFS服务器

6. 目标环境设置uboot参数

7. 制作根文件系统（optional）。

8. 完整的启动LOG。

有几位网友发信问我uboot挂载文件系统的方法，其实这个部分也不是我原创的，大部分都是参考其他网友的方法，现在将我的手顺记录下来，希望对大家有所帮助。

整体思路大概是这样：

* 将uboot烧写到SD卡。

* 从SD卡启动系统，SD卡中的uboot通过TFTP协议将远程的的Kernel下载到内存中。 * uboot将内核参数设定为ROOT分区为远程的NFS-SERVER共享的一个目录，并JU MP到内核的START ADDRESS。

* kernel自解压，并JUMP 到解压后的新的内核START ADDRESS，内核正常启动。 * 最后通过内核通过uboot设置的ROOTFS参数得知根文件系统在远程，并通过NFS 挂载ROOTFS。

*
