DB2 Version 9.7 for Linux, UNIX, and Windows

Creating links for DB2 files

To perform this task, you must be logged on as a user with root authority.

This task is not required for normal DB2 operation.

Consider creating links for the DB2 files only if both of the following conditions are met:

• You have only one copy of DB2 on the current computer.
• You are developing or running applications and want to avoid having to specify the full path to the product libraries and include files.

The following restrictions apply:

• Creating links for one DB2 copy will render the other DB2 copies nonfunctional. Links can be established for only one DB2 copy on a given system.
• If there are existing links to the /usr/lib and /usr/include directories from a previous DB2 version, they will automatically be removed.
• Links must not be created on systems where multiple DB2 copies are intended to coexist.

To create links for DB2 files:

1. Log on as a user with root authority
2. Run the db2ln command. For example:

        DB2DIR/cfg/db2ln

   where:

   DB2DIR

   is the DB2 installation directory.

   • On AIX®, HP-UX, or Solaris operating systems, the default DB2 installation directory is /opt/IBM/db2/V9.7
   • On Linux® operating systems, the default installation directory is /opt/ibm/db2/V9.7

If there are existing links to the /usr/lib and /usr/include directories from a previous DB2 version, they will automatically be removed by entering the db2ln command to create links for this DB2 version. If you want to reestablish the links to the libraries of the previous version, then you must run the db2rmln command from your current DB2 version before you run the db2ln command from the previous DB2 version.
