Oracle eMail Server Installation Guide Release 5.2 Part Number A86742-01 |
|
This chapter describes the preinstallation procedures for Oracle eMail Server. Topics covered include:
Oracle eMail Server is a highly scalable messaging framework that integrates messages from multiple sources into a single inbox. Prior to installation, you should plan your implementation strategy and be familiar with Oracle eMail Server system components, concepts, and terminology.
The installation process is composed of the following steps:
acme.com
as opposed to us.acme.com
and uk.acme
.com, for instance)
The following system and software requirements are required to install Oracle eMail Server.
Oracle eMail Server requires the following hardware for Windows NT installation:
Oracle eMail Server requires the following software components and associated versions:
The minimum RAM requirements for Oracle eMail Server, administration tool, and the protocol server depend upon the number of machines on which these products are installed.
Oracle eMail Server Components | Minimum RAM Requirements |
---|---|
Oracle eMail Server |
128 MB |
Administration Tool |
64 MB |
IMAP4 and POP3 Protocol Server |
20 MB |
The following disk space is required for Oracle eMail Server:
Oracle eMail Server Components | Minimum Disk Space Requirements |
---|---|
Oracle eMail Server |
500 MB |
Administration Tool |
100 MB |
IMAP4 and POP3 Protocol Server |
65 MB |
The following tasks must be performed prior to installing Oracle eMail Server:
Perform a full backup of your existing Oracle8i Database Server before you perform any new installation or upgrade. A full backup ensures that you can recover from errors encountered during an installation or upgrade processes.
The backup should be performed with the database shut down cleanly. If you use shutdown immediate
or shutdown abort
to force users off the system, be sure to restart the database in restricted mode, and then shut it down with normal mode. See the Oracle8i Administrator's Guide or Oracle8i Backup and Recovery Overview for more information.
Oracle eMail Server requires reconfiguration of specific database parameters. Before starting the configuration, shut down the network listener and the database where Oracle eMail Server will be installed.
To shut down all Oracle instances including the network listener, use the following procedure:
init
SID.ora
file located in the ORACLE_HOME
\database
directory to reflect the following minimum values for the listed parameters:
Use the following steps to configure the NLS_LANG
parameter toAMERICAN_AMERICA.UTF8
.
regedit
from the dropdown menu or type regedit
in the field.
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE
.
HOME_NAME
folder.
NLS_LANG
parameter.
AMERICAN_AMERICA.UTF8
From the NT Services tool:
Choose Start > Settings > Control Panel > Services. The Services window displays. Select the OracleHome
SID
process and click Start.
From the command prompt:
Choose Start > Programs > Command Prompt. Enter the following:
C:\>cd ORACLE_HOME
\bin
C:\>sqlplus
enter user-name: system
enter password: manager
SQL> startup
SQL> exit
From the NT Services tool:
Choose Start > Settings > Control Panel > Services. The Services window displays. Select the Oracle
HOME_NAME
TNSListener
process and click Start.
From the command prompt:
Choose Start > Programs > Command Prompt. Enter the following:
C:\>lsnrctl start
If you are installing a DCN or member node, configure Net8 to enable the new node to connect to the host server.
The following are methods for configuring Net8:
Use an Oracle Names server to simplify the setup and administration of global client/server computing networks by maintaining a central directory of service names for all the services on the network.
If you are not using an Oracle Names Server, you must add entries to the tnsnames.ora
configuration file.
tnsnames.ora
file in theORACLE_HOME
\network\admin
directory.
connect_string
= (DESCRIPTION= (ADDRESS=( PROTOCOL= TCP)(HOST=host_server_name
)(PORT= 1521)) (CONNECT_DATA= (SID=sid
)))
Follow these guidelines when adding entries:
tnsnames.ora
file must contain an entry for each Oracle eMail Server node to which you want to connect.
tnsnames.ora
file should be copied to each node that will be part of the network configuration.
The following is an example:
host1,io1,host1.us.oracle.com,io1.us.oracle.com = (DESCRIPTION = (ADDRESS = (PROTOCOL= TCP) (HOST= iosun-test1.us.oracle.com)(PORT=1521)) (CONNECT_DATA = (SID= io1)))
tnsnames.ora
file:
C:\>tnsping host
C:\>lsnrctl start
listener.ora
and tnsnames.ora
files are automatically configured during the installation of an Oracle database. They are located in the ORACLE_HOME
\network\admin
directory.
Verify that the listener.ora
file contains entries for an IPC key EXTPROC and a SID PLSExtProc.
(KEY=EXTPROC) (SID_NAME=PLSExtProc)
Verify that the tnsnames.ora
file contains an entry for
EXTPROC_CONNECTION_DATA that uses the IPC key EXTPROC and SID PLSExtProc.
For the following two steps, use the Net8 Assistant. To start the Net8 Assistant choose Start > Programs > Oracle - HOME_NAME
> Network Administration > Net8 Assistant.
listener.ora
file contains entries for an IPC key EXTPROC
and a SID plsextproc
.
tnsnames.ora
file contains an entry for EXTPROC_CONNECTION_DATA
that uses the IPC key EXTPROC
and SID plsextproc
.
The library oratnsapi8.dll
is a network dll
and needs to be included in the system path. Usually, the file is located in theORACLE_HOME
\network\tnsapi\bin
directory.
Use the following steps to amend the system path:
oratnsapi8.dll
library to the end of the string. Use a semicolon to separate the last entry from this additional entry. For example: ;D:\oracle\ora81\network\tnsapi\bin
directory.
The Oracle Internet File System e-mail component and Oracle eMail Server both use Sendmail for mail transfer. Windows NT and Windows 2000 installations require purchasing Sendmail version 3.0 or 3.0.2, respectively, for both e-mail components.
To run Oracle Internet File System and eMail Server on the same machine, configure them using the following procedure:
sendmail.cf
file.
sendmail.cf
file, using the procedure outlined in Chapter 3, "Postinstallation".
If you incorporate the eMail Server configuration changes into the sendmail.cf
file and then run the scripts, the scripts will generate a new sendmail.cf
file.
If the IMAP servers provided by Oracle Internet File System and eMail Server are to be run on the same machine, configure them to listen on different ports. Use the Oracle Internet File System configuration utility and the eMail Server Administration tool to specify the port for the component.
For example, configure eMail Server to listen on the default port 143 and configure the Oracle Internet File System IMAP server to listen on some other port, as required by the installation.
The clients accessing the IMAP servers must have accounts mapped to these specific ports. To access both servers at the same time, use clients that allow you to set the IMAP servers on two different eMail Server installations.
