Database Preinstallation Tasks

Add environment variables and required values to the $PATH variable.

The choices you see in the installation program depend on what the installation program detects in the $PATH variable on the Lawson server machine.

1. Define an environment variable for the $DB2HOME directory.

   $DB2HOME The value must be equal to DB2INSTANCE /sqllib (the sqllib subdirectory in the home directory of the DB2 instance owner).

2. Verify that the database location is in the $PATH variable.

   Note: If you plan to install GEN, LOGAN, and/or Lawson applications in different databases, all the directories must be in your path.

3. Verify that the directory containing the command to start the database client appears in your $PATH.

4. Add the directory containing the database libraries to the shared library path on your Lawson server machine.

For information and instructions, see the documentation provided with the database and/or the operating system.

The installation location of the GEN, LOGAN, and application databases.

The $DB2HOME directory path for each instance.

Determine the initial number of simultaneous database connections

The installation program asks for the number of simultaneous database connections that you allow. A database connection is one driver job, or one open data area for each running program.

The default value is 500; you may need to increase this value significantly. Use this value to calculate the starting values of the USERS, FOREIGN, and IFILES parameters in the Lawson ladb.cfg file. Individually tune these values as required after installation.

Determine the local alias for the DB2 database

or

Determine the name of the database on the DB2 database server

The DB2 client must be installed and configured to connect to the DB2 server. This value is the alias name as cataloged on the local system.

Determine database user name (ID) and password

• The login name (user name) and password for the database user who accesses Lawson data at run-time.

  These values are mapped to the LOGINNAME and PASSWORD parameters in the IBM database driver configuration file.

Determine the schema to use when creating tables

Use the schema name to keep the data for this Lawson data set separate from any other data stored in the database. All tables are created with this name as the table owner.

Use a unique schema name for each Lawson data area. Lawson recommends that you use the format EnvironmentName_DataAreaName; for example, 100TEST_GEN and 100TEST_LOGAN. The schema name cannot exceed 18 characters in length.

Determine how to configure and name IBM DB2 table spaces

Table spaces for tables and indexes must be defined in IBM DB2.
