Because a DB2 copy already exists on the system and the default installation path/opt/ibm/db2/V9.7 is used during installation, you must specify the installation path for the DB2 copy to be installed. If you use
1. view the current DB2 copy on the system:
[Root @ localhost home] # db2ls
Install Path Level Fix Pack Special Install Number Install Date Installer UID
Bytes ---------------------------------------------------------------------------------------------------------------------
/Opt/ibm/db2/V9.7 9.7.0.7 7 Fri Dec 7 01:58:51 2012 CST 0
The current DB2 version on the system is 9.7.0.7, and the copy installation path is/opt/ibm/db2/V9.7.
2. view the user and group information of the current DB2 instance on the system:
[Db2inst @ localhost home] $ ls-l
Total usage 20
Drwxr-xr-x. 4 dasusr dasadm 4096 02:05 dasusr
Drwx ------. 3 db2fenc db2fgrp 4096 November 30 21:46 db2fenc
Drwxr-xr-x. 10 db2inst db2grp 4096 December 12 05:26 db2inst
Drwxr-xr-x. 3 root 4096 December 12 05:28 db2install
The current instance owner db2inst is in the db2grp group. The DAS user is dasusr and the group is dasadm. The protected user is db2fenc and the group is db2fgrp.
Since each computer can only have one DAS, there is no need to create a new copy of the DAS, there is no need to create a corresponding DAS user.
3. Create instance owner users and groups for the new DB2 copy instance:
[Root @ localhost home] # groupadd db2grp2
[Root @ localhost home] # useradd-g db2grp2-d/home/db2inst2-s/bin/bash db2inst2
[Root @ localhost home] # passwd db2inst2
4. Because a DB2 copy already exists on the system and the default installation path/opt/ibm/db2/V9.7 is used during installation, you must specify the installation path for the DB2 copy to be installed. If you use the "DB2 installation" Wizard to install a new copy, you do not need to specify the installation path. The default path is/opt/ibm/db2/V9.7 _##, the value range of # is 01 to 99 ,. Here, the installation path is:
[Root @ localhost ~] # Mkdir/opt/ibm/db2/V9.7 _ 01
5. Use the root user to install a new DB2 copy. Note that non-root users cannot install multiple DB2 copies.
[Root @ localhost db2install] # ls
Server v9.7fp5_linuxia32_server.tar.gz
-- The installation package has been decompressed.
[Root @ localhost server] #./db2_install-B/opt/ibm/db2/V9.7 _ 01-p ESE-n
-B: Specify the installation path.
-P productShotName: Specifies the DB2 database product to be installed. This parameter is case insensitive. When the-n parameter is specified, the-p parameter must be specified. You can find the product short name (productShotName) in the componentlist.htm file in the/home/db2install/server/db2/linuxdirectory ). The short name of the product is as follows:
DB2 Enterprise Server Edition: ESE
DB2 Connect Server: CONSV
DB2 Workgroup Server Edition: WSE
DB2 Express: EXP
DB2 Personal Edition: PE
IBM Data Server Client: CLIENT
IBM Data Server Runtime Client: RTCL
-N: indicates the non-interactive installation method. If this parameter is specified,-B and-p must be specified.
