Setting the UNIX Environment

You need to set environment variables so you can access the database instance that was created when the database manager was installed. The DB2 for UNIX Quick Beginnings book provides general information about setting environment variables. This section provides specific instructions on setting environment variables to access a database instance.

Each database manager instance has two files, db2profile and db2cshrc, which contain scripts to set the environment variables for that instance. Depending on the shell you are using, run the script by entering:

For bash or Korn shell:

. $HOME/sqllib/db2profile

For C shell:

source $HOME/sqllib/db2cshrc

where $HOME is the home directory of the instance owner.

For your convenience, you may want to include this command in your .profile or .login file, so that it runs automatically when you log on.

Depending on the UNIX platform you are on, the following environment variables are automatically updated during DB2 instance creation:

AIX:

• PATH, to include several DB2 directories including sqllib/bin
• LIBPATH, to include the directory sqllib/lib

HP-UX:

• PATH, to include several DB2 directories including sqllib/bin
• SHLIB_PATH, to include the directory sqllib/lib

Linux, PTX, and Solaris:

• PATH, to include several DB2 directories including sqllib/bin
• LD_LIBRARY_PATH, to include the directory sqllib/lib

Silicon Graphics IRIX:

• PATH, to include several DB2 directories including sqllib/bin
• LD_LIBRARY_PATH, to include the directory sqllib/lib (needed for o32 object type applications)
• LD_LIBRARYN32_PATH, to include the directory sqllib/lib32 (needed for n32 object type applications)

For the Java environment variables updated by DB2, see "Setting the Environment".
