DB2 OLAP Server Version 8.1 offers your enterprise the option of installing the
client components from a shared network file server. The alternative is to
install the clients locally, one at a time, directly from the CD.
Installing clients over a network has the following advantages over locally
installed clients:
- The users in your enterprise can all use the same level of client.
- You can deploy clients to larger numbers of users at the same time, which
is often faster than passing a CD from user to user.
- You can apply FixPaks to the common client code and have your users upgrade
together.
- The network clients take up less disk space than locally installed clients.
Although network clients offer the same function as locally installed clients,
there are important difference between them:
- Locally installed clients
- Locally installed clients are installed directly from the CD. They include
all the client executable files. The installation program adds Start menu
shortcuts, updates the Windows registry, and updates environment variables.
Because client operations are completely local and do not load or interpret
code over a network, local clients might offer better performance than network
clients.
- Network clients
- Network clients are installed from a file server. They do not include
any executable files, and therefore take up less room and store fewer files
than locally installed clients. The installation program adds Start menu shortcuts, updates the Windows registry, and updates environment
variables. Network clients all use the same language and connect to the server
using the same network protocol.
The network client feature installs clients of DB2 OLAP Server and DB2 OLAP Integration Server. OLAP Miner
clients are not enabled for network installation; they must be installed directly
from the CD.
There are two major steps in setting up a network installation, and they
are performed by two different users:
- The system administrator runs the DB2 OLAP Server installation program to load
the client image onto the file server. The computer from which the system
administrator does this is called the image owner computer. The client image
consists of executable files plus a second installation program that your
network client users can run to install the network clients. See Loading the client image onto the network.
- The network client users install the network clients by running run the
second installation program. See Installing the clients from the network.
The instructions in this section are intended for the system administrator,
who loads the common client image onto the network.
Before you begin, you need to designate one client computer as the client
image owner, and decide which user ID you will use to load the client image:
- The image owner computer can be any computer on the network that satisfies
the following criteria:
- The user ID with which the image owner computer accesses the file server
must have administrator authority and read/write privileges on the file server.
To load the client image onto the network:
- Connect to the file server. Whatever drive letter you assign will be the
same drive letter that the network client users must use when they connect
to the file server. For example, if you designate the file server as the p: drive, the network client users have to connect the file server as
their p: drive.
- Insert the DB2 OLAP Server CD into the CD drive on the computer that you designate
as the client image owner computer. If the installation program does not start
automatically, run the setup.exe file in the \Win32 directory
of the CD.
- On the IBM DB2 OLAP Server Setup panel, click Next.
- On the Software License Agreement panel, read the licence terms. If you
accept them, click Accept.
- On the Select Installation Options screen, select Client. A box called Store executables on network appears. Click it and then click Next.
- On the Select Options Purchased panel, select the optional features your
enterprise has purchased and click Next.
- On the Choose Destination Location screen, select the drive letter of
the file server from the Drive box.
- In the Directory field, either accept the
default value or click Browse to select a different
path name. Click Next.
- On the Select Installation Type panel, select either Typical, Compact, or Custom. It is recommend that you select Custom so you can select which online books are installed with the network
client. If you choose Typical or Compact, the installation program only installs a small subset of the
documentation. Click Next.
If you selected Custom, the Select Components panel appears. Open
the Client and Server Documentation item in the tree view and select the documentation
you want to make available to the network client users. It is recommended
that you select all the documentation the network client users will need.
Click Next.
- On the OLAP User Information panel, enter the user ID and password of
the super user, which is the user ID that you use to connect the client image
owner computer to the file server. This user ID must have administrator authority
and read/write privileges on the file server. Click Next.
- On the Select Folder panel, either accept the default name of the folder
or enter a new one. Click Next.
- On the Start Copying Files panel, click Next. The network client image is copied to the file server.
The next step is to inform the network client users how they can install
the network clients. They need the following information:
- The drive letter that you selected when loading the client image onto
the file server. The network client users must select the same drive letter
when they connect to the file server.
- The directory on the file server that contains the installation program
for the network clients.
- The path of the OLAP server components. The path is set in the ARBORPATH
variable.
The next section, Installing the clients from the network, describes how this information
is used when installing the network clients.
The instructions in this section are intended for the network client user,
who installs the DB2 OLAP Server clients from the file server. The examples in this
section assume the system administrator installed the network client image
on the p: disk and accepted the default value for the installation
directory (p:\ibm\db2olap).
If you already installed DB2 OLAP Server directly from a CD, you cannot run this
installation program.
Before you begin, you need the following information from your system administrator:
- The drive letter you must use to connect to the file server, and the directory
in which the system administrator loaded the installation program.
- The path of the OLAP server components.
- The language of the OLAP clients. The system administrator selects which
language the clients are in, and you must select the same language. If you
install the clients, your computer must be configured in the same language,
or results might be unpredictable.
To install the clients from the network:
- Connect to the file server where the system administrator loaded the client
image package. Assign the same drive letter to the file server that the system
administrator used. You must always use the same drive letter when you connect
to the file server, to the OLAP clients will not work.
- Change directories to the location of the installation program, such as
the p:\ibm\db2olap\install\ directory.
- Run the netinst.exe command to start the the installation program.
- On the Location to Save Files panel, select the directory where you want
to install the OLAP clients and click Next.
- On the OLAP Network Installation panel, click Next.
- On the Choose Destination Location panel, enter the path from which you
are installing the OLAP clients. It is the same as the location of the netinst.exe command.
- On the OLAP Network Installation Language Selection screen, select the
language that your administrator supplies to you.
- On the Start Copying Files panel, click Next. After the installation program completes, reboot your computer.
Whenever you connect to the file server to use the OLAP clients, use the
same drive letter you used when you installed them.
The installation program creates a log file called olap81cli.log that
contains information about the components installed.
To uninstall the clients, the run netinst.exe again and select
the Remove option. The program removes the shortcuts and updates
to the Windows registry and environment variables on the client computer.
Uninstalling the network clients from your client computer does not affect
any files on the server or the image owner computer.
IBM FixPaks for DB2 OLAP Server can apply service upgrades to the client image stored
on the file server.
The following steps describe how to to apply FixPaks for common clients:
- The system administrator logs on to the image owner computer.
- The system administrator connects to the file server using the same user
ID under which the common client image was originally loaded onto the file
server.
- The system administrator runs the FixPak installation program.
- The network client users connect to the file server and run the updated netinst.exe file to apply the FixPak to their computers. If there are
new client products in the client image, then they will be added to the user's
computer. If clients were removed from the file server, then they will be
removed from the user's computer.
If the image owner computer crashes or is removed from the system, the
network client users can continue running the clients. However, the system
administrator cannot apply FixPaks without first taking the following steps:
- Designate a new client image owner computer.
- Remove the common client image from the file server.
- Reinstall the original network client image from the new client image
owner computer.
- Apply the FixPak as described in this section.
