Quick Beginnings for DB2 Universal Database EEE for Windows NT**


Before You Begin

Before you begin the installation, be sure that you have the following items and information:

__  1.

Ensure that all of the machines that will participate in this partitioned database system:

__  a.

Meet all the requirements outlined in Planning for Installation.

__  b.

Belong to the same Windows NT domain.

__  c.

Have consistent time and date settings.

Figure hint not displayed.

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.

__  d.

Have a TCP/IP port range free that spans 4 port numbers. This port range will be used by the Fast Communications Manager (FCM). FCM is a feature of DB2 that handles communications between database partition servers. The port range you select must be available on every machine that will participate in the partitioned database system. By default, the setup program will generate a range for you, use this port range or provide your own.

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: is the drive where you installed Windows NT).

Make note of this port range here: ______ to ______.

Figure hint not displayed.

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.

__  e.

Have a TCP/IP port free for use by the DB2 Performance Monitor. The port you select must be available on every machine that will participate in the partitioned database system. By default, the setup program will generate a value for you, use this port or provide your own.

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: is the drive where you installed Windows NT).

Make note of this port here: ______.

__  f.

Can communicate with each other using TCP/IP. To ensure that two machines can communicate with each other using TCP/IP, perform the following steps:

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 paulz.torolab.ibm.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.

__  2.

A domain user account that belongs to the Local Administrators group on the machine where you are going to perform the installation. The user account you specify must be locally defined on every machine that will participate in the partitioned database system.

This user account must also have the "Act as part of the operating system" advanced user right. For more information on user rights, refer to the Windows NT online help.

Figure hint not displayed.

You can perform the installation without the Act as part of the operating system advanced user right, however, the setup program will be unable to validate the account that you specify for the Administration Server. We recommend that any user account used to install this product have this advanced user right.

__  3.

During installation, you will be asked to provide a user account that will be used by the Administration Server to log on to the system and to start itself as a service.

By default, the setup program will set up a user account with the username db2admin and password db2admin. You can accept these values, or provide your own. 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 D, Naming Rules.

Figure hint not displayed.

If you use the default user account db2admin, and do not change the default password on the setup window, you should change this password immediately following the installation. This password is the default used for any installation, and therefore is well known. Using this password could pose a security risk to your network.

You must also change the password for the DB2-DB2DAS00 service to match the new password that you specify for the db2admin username. To change the password that is associated with the Administration Server, entering the following command:

   db2admin setid username password

__  4.

To verify that DB2 installed correctly, you will need to have a user account that belongs to the System Administrative (SYSADM) group, is 8 characters or less, and complies with all of DB2's naming rules.

By default, any user 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 D, Naming Rules.
