Configuring IBM Communications Server for Linux

Communications Server for Linux requires a number of environment variables to be defined.

Refer to the README file supplied with the SNA product and ensure that all variables are correctly set, including LD_PRELOAD. It is recommended that you set LD_PRELOAD in ctgd.conf so that the library is only loaded for the Client daemon process. The LD_PRELOAD environment variable must be set to a 32-bit shared object to allow the 32-bit Client daemon process to communicate with the SNA product. Read the man page for ld.so for information about security issues associated with LD variables.

To ensure that messages can be written to error logs, the user who starts the Client daemon process must be a member of the "sna" group.

Using IBM Communications Server for Linux Remote API client V6.3

IBM® Communications Server for Linux Remote API Client V6.3 and later does not require the LD_PRELOAD environment variable of the Linux streams (LiS) library. To stop the Client daemon generating warning CCL4678W, set LD_PRELOAD to an empty string, for example:
 export LD_PRELOAD=""
