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.
On Windows, the installation sets all necessary environment variables.
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.
If Replication Agent is installed on Solaris, AIX or HP Itanium, you must configure a 64-bit IBM DB2 Universal Database server or client instance.
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.
Replication Agent requires 32-bit libraries for Linux and Windows and 64-bit libraries for UNIX. Because ECDA may have different requirements, you may want to maintain two separate customized copies of the aforementioned scripts, one copy for Replication Agent and one for ECDA.
