Before you begin the installation, be sure that you have the following items and information:
![]() | To be considered consistent, the difference in GMT time between all machines that participate in a partitioned database system must be within 1 hour. You can use the max_time_diff configuration parameter to change this restriction. For more information, refer to the Administration Guide. |
To review the TCP/IP ports that are already in use, open the services file located in the x:\winnt\system32\drivers\etc directory, where x: represents the drive where you installed Windows.
Make note of this port range here: ______ to ______.
![]() | If you plan to run multiple logical nodes (MLNs) on any of the machines
that will participate in your partitioned database system, then you must
specify a port range that spans the number of MLNs on the machine running the
most MLNs.
For example, if you had a database partition server that was running 6 database managers (by installing a database partition server and then adding 5 logical nodes) you would need to specify 6 consecutive ports as your port range for the installation. For more information, refer to the Administration Guide. |
To review the TCP/IP ports that are already in use on a machine, open the services file located in the x:\winnt\system32\drivers\etc directory, where x: represents the drive where you installed Windows.
Make note of this port here: ______.
Step 1) | On a machine that will participate in this partitioned database system, enter the following command: hostname This command will return the hostname of this machine |
Step 2) | On another machine that will participate in this partitioned database system, enter the following command: ping hostname You will receive output similar to the following: Pinging myserver.com [9.21.27.230] with 32 bytes of data: Reply from 9.21.27.230: bytes=32 time<10ms TTL=128 Reply from 9.21.27.230: bytes=32 time<10ms TTL=128 This output verifies that both machines can communicate with each other.

![]() | If you are planning to use multiple network adapters, you must use the db2nchg command to specify the TCP/IP address for the netname field in the db2nodes.cfg file. For more information, you can refer to the Administration Guide, or to Changing the Database Partition Server Configuration. |
This user account must also have the "Act as part of the operating system" advanced user right. For more information on granting advanced user rights, refer to Granting Advanced User Rights on Windows.
By default, the setup program will create a user account with the user name db2admin and the password you supply. You can accept the default user account, create your own user account by modifying the default value, or provide your own user account. If this account already exists on your system, you must use the password that was previously set for this user account. If you provide your own user account, you must ensure that it conforms to DB2's naming rules. For more information, see Appendix C, Naming Rules.
By default, any local user account that belongs to the Local Administrators group, on the local machine where the account is defined, has SYSADM authority on the instance. For more information, see Working with the System Administrative Group. For more information on valid DB2 usernames, see Appendix C, Naming Rules.
To extend the directory schema, execute the db2schex.exe program from the installation CD with Schema Admins authority. You can execute this program with Schema Admins authority, without logging off and logging on again, as follows:
runas /user:MyDomain\Administrator x:\db2\common\db2schex.exe
where x: represents the CD-ROM letter. When db2schex.exe completes, you can continue with the installation.
