There are several prerequisites and some information you must be aware of before you build the reference environment.
For Oracle, verify that you have execute permission in the Oracle release directory. For example, verify whether you can manually create an instance.
Verify that the environment variable settings in the SYBASE.sh file in the Replication Server or Adaptive Server release directory is correct. If you cannot verify this, remove or rename the file.
Verify that you have the UNIX grep, kill, awk, and ps commands available in your bash shell.
The reference implementation procedure uses the interfaces file in the Replication Server release directory. If the file exists before you run the reference implementation procedure, the procedure backs up the existing file by incrementing the file name extension.
For Oracle, the reference implementation procedure renames the existing tnsname.ora, listener.ora files and creates new files for the Oracle reference implementation.
