Set the IBM DB2 Universal Database environment variables.
For UNIX and Linux, the IBM DB2 Universal Database installation provides two scripts for setting up the IBM DB2 Universal Database environment variables: db2cshrc for C shell and db2profile for Bourne or Korn shell. These scripts set the library path environment variable based on the bit size of the installed server or client.
For UNIX and Linux platforms, the 32-bit and 64-bit versions of the driver and API libraries are located in $HOME/sqllib/lib32 and $HOME/sqllib/lib64, respectively, where $HOME is the home directory of the IBM DB2 Universal Database instance owner. If Replication Agent is installed on AIX, Solaris, or HP Itanium, the library path environment variable must point to the 64-bit libraries. For all other platforms, the library path environment variable must point to the 32-bit libraries.
To correctly set the IBM DB2 Universal Database environment variables for Replication Agent and ECDA, you may need to customize either db2cshrc or db2profile. However, make any changes to saved copies of the original scripts because the scripts may be changed when you apply a FixPak to the IBM DB2 Universal Database server or client.
