This chapter contains installation
prerequisites and instructions for installing BEA TUXEDO on
Windows NT. It also contains information on upgrading an existing
BEA TUXEDO System.
BEA TUXEDO System for Windows NT
interoperates with BEA TUXEDO System 6.3 on all supported
platforms as master and nonmaster. All currently supported
versions of workstation on the various platforms work with this
release.
During installation, the following activities
occur:
During the installation of BEA TUXEDO 6.3 on
Windows NT, the system environment is modified. One of these
modifications is the PATH environment variable. When an
application is loaded, the link loader checks the local
directory, followed by the system PATH, user PATH, and finally
the path set in autoexec.bat (if applicable). Because different
versions of a DLL can exist in a system, it is critical to verify
that the correct DLL version is loaded.
You do this by ensuring that the first BEA
TUXEDO-related pathname in your system path is the pathname for
the root directory of the BEA TUXEDO software or %TUXDIR%. To do
this, perform the following steps.
- Select Start
Control
PanelSystemEnvironment.
- Scroll through system variables to
ensure that the first instance of TUXDIR points to BEA
TUXEDO Release 6.3.
- Set Variable and Value as necessary and
click OK.
- Restart the computer.
A further complication is that a DLL may be
loaded in memory. As applications are loaded, they first attach
to the library in memory, which may cause applications to attempt
to load the incorrect DLL version. To prevent this, shut down all
BEA TUXEDO processes before installing Release 6.3. (Microsoft's©
Resource Kit for Windows NT provides additional
information.)
To install BEA TUXEDO on Windows NT
correctly, the person installing the application needs to log in
with the user ID of Administrator.
If someone logs in from a non-administrator
account, the TUXIPC service will not have an entry in the
registry. BEA TUXEDO is still functional however, because TUXIPC
runs as a process, but all applications terminate when the user
logs off.
You are offered three types of installations
(for either the SDK or RTK package):
As part of the installation process, the BEA
TUXEDO IPC Helper Service is installed as an NT Service; general
installation information as well as the IPC parameters are
installed in the registry. The layout of the registry is as
follows:
HKEY_LOCAL_MACHINE\Software\BEA
Systems\TUXEDO\6.3
Product information, such as the major and
minor version numbers of the release, user and company names, is
stored under the Release 6.3 key.
Values for the BEA TUXEDO IPC Helper Service,
as well as location of TUXDIR, NLSPATH, ULOGDIR, ULOGPFX,
ULOGOUT, are stored under the Environment key. You can tune the
IPC values based on your application needs. (Refer to the control
panel applet described in Chapter 3, Configuring BEA TUXEDO
for Windows NT.)
The Security key has the following
requirements:
- Log in to Windows NT with the user name Administrator.
- Insert the BEA TUXEDO CD-ROM in the
CD-ROM drive and select StartProgramsWindows
NT Explorer.
- Select the CD-ROM icon and choose one of
the following actions.
- Follow the window prompts.
- After you get a message that the
installation was successful, reboot the machine.
Note: You can also select
StartRun or begin installing from
a command prompt. Both installations prompt you for the
license diskette before installing.
If you are upgrading from an existing BEA
TUXEDO System, and are using the BEA TUXEDO IPC Helper Service,
you must stop the service and then proceed with the installation
procedure.
- Disable the BEA TUXEDO IPC Helper
Service, by selecting StartSettingsControl
PanelServices.
- From the Services dialog box, select TUXEDO
IPC Helper and then select Stop.
- Insert the BEA TUXEDO CD-ROM in the
CD-ROM drive and select StartProgramsWindows
NT Explorer.
- Select the CD-ROM icon and choose one of
the following actions.
- Follow the window prompts.
- After you get a message that the
installation was successful, reboot the machine.
Note: To ensure proper
operation, regenerate any applicable TUXCONFIG files.
