---------------------------------------------------------------------------------------------------------------------
/opt/ibm/db2/V9.7 9.7.0.5 5 Thu Dec 10 08:45:27 2015 EST 0
2、查看详细已安装DB2版本
[root@db2-node01 db2inst4]# /opt/ibm/db2/V9.7/bin/db2level
DB21085I 实例 "db2inst4" 使用 "64" 位和 DB2 代码发行版
"SQL09075"，级别标识为 "08060107"。
参考标记为 "DB2 v9.7.0.5"、"s111017" 和 "IP23292"，修订包为 "5"。
产品是在 "/opt/ibm/db2/V9.7" 处安装的。
3、查看当前运行实例
[root@db2-node01 db2inst4]# /opt/ibm/db2/V9.7/instance/db2ilist
db2inst4
[root@db2-node01 db2inst4]# su - db2inst4
[db2inst4@db2-node01 ~]$ db2level

数据库发行版级别 = d.00
注释 =
目录条目类型 = 间接
目录数据库分区号 = 0
备用服务器主机名 =
备用服务器端口号 =
二、安装装DB210.5
1、使用root用户解压安装
[root@db2-node01 db2inst4]# tar -zxvf v10.5_linuxx64_server_t.tar.gz
2、升级前环境检查
[db2inst4@db2-node01 ~]$ /home/db2inst4/server_t/db2ckupgrade -e -l ~/1.log
DBT5508I db2ckupgrade 实用程序已成功完成。可以对数据库进行升级。
[db2inst4@db2-node01 ~]$
Run installation with the option "-f sysreq" parameter to force the installation.
3、安装db210.5软件
[root@db2-node01 db2inst4]# /home/db2inst4/server_t/db2_install
DBI1324W Support of the db2_install command is deprecated. For
more information, see the DB2 Information Center.
