- [root@centos-0 instance]# ./db2icrt -u db2inst1 db2inst1
- The host name "centos-0.msdomain" is invalid. Specify a valid host name.
- DBI1922N The host name is not valid.
-
- Explanation:
-
- The TCP/IP host name parameter is not valid or does not exist.
-
- User response:
-
- Ensure that TCP/IP is operational on the system. If a domain name server
- is used, ensure that the domain name server machine is active. Issue the
- command again using the correct TCP/IP host name.

- /opt/ibm/db2/V9.7/instance/db2iutil: line 2528: DB2INSTVER: parameter null or not set
检查 /opt/ibm/db2/V9.7/instance/db2iutil 文件(非提示的2528行),发现有如下内容
- ${DB2DIR?}/instance/db2isrv -addfcm -i ${INSTNAME?} ${DB2ISRVOPTS?}
-
-
- if [ $? -eq 3 ]; then
-
- db2isrv
-
-
-
- ${DB2DIR?}/instance/db2isrv -addfcm -i ${INSTNAME?} ${DB2ISRVOPTS?}
- if [ $? -eq 3 ]; then
- display_msg ${DB2CAT?} 922 \
- 'DBI1922N The host name is not valid.\n'
-
- 就是当db2isrv -addcfm -i ${INSTNAME?} ${DB2ISRVOPTS?} 返回为3的时候提示主机名称不正确。
- 这个db2isrv 找了很多东西,没找到具体的内容,看名字是给系统增加一个服务。后面是addfmc ,这个fmc是DB2的故障守护进程。
- 这个是监测DB2实例正常运行,当实例异常宕机后,它会自动启动实例。那么以上的错误可以连起来了:
- 再给系统增加一个DB2守护进程的时候失败了,原因是主机名不对。
-
- 好的,看一下主机名定义
- [root@centos-0 instance]# hostname
- centos-0.msdomain
- 再看
- [root@centos-0 instance]# vi /etc/hosts
- 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
- ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
-
- 这个地方不知为什么CENTOS装好之后没有修改,修改一下。修改后内容如下
-
- [root@centos-0 instance]# vi /etc/hosts
- 127.0.0.1 localhost centos.msdomain localhost4 localhost4.localdomain4
- ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
- 保存再次执行创建实例,正常。
