Replication Server 12.6 retains almost the same installation directory structure as version 12.5. Most components are installed in their own subdirectories, with the executable program, installation and configuration tools, and display-related files needed by the component. The naming convention for subdirectories includes a component identifier, such as REP (for Replication Server) or OCS (for Open Client™ and Open Server™), and the software release version, such as 12_6 or 1_0.
WARNING! Do not install Replication Server version 12.6 on top of the following Sybase products:
Replication Server version 12.5 or earlier
Adaptive Server version 12.5.0.x or earlier
Open Client/Server version 12.5.0 or earlier
OpenSwitch version 12.5 or earlier
DirectConnect version 12.5 or earlier
Doing so incapacitates older versions of these products, and can also adversely affect other Sybase products.
You cannot reverse this with an uninstallation, as this could remove required components of the older Sybase products updated by Replication Server version 12.6. For this reason, Sybase recommends that you back up your current directory before installing Replication Server version 12.6.
Shared components are installed in subdirectories that are separate from component subdirectories. For example, the Replication Server subdirectory is %SYBASE%\REP-12_6; however, localization files are installed in %SYBASE%\locales; and the Replication Manager plug-in for Sybase Central, Java Edition, RMPlugin.jar, and its associated files are installed in %SYBASE%\RMP-12_6. The exception is Adaptive Server® Anywhere (ASA), which is installed in %SYBASE%\REP-12_6\ASA8. As a result, the directory structure enables you to install into an existing 12.6 %SYBASE% directory structure, as well as to install and use multiple versions of some components.
If your earlier installation includes custom applications
or scripts that refer to %SYBASE% subdirectories,
change them to reflect the new installation directory structure.
Three diagnostic servers, REP-12_6\bin\drepsrvr.exe, REP-12_6\bin\dltm.exe, and RSM12_6\bin\drsmsrvr.exe, are installed to capture and display information about internal processes. Do not delete these programs; you may need to use them, at the direction of Sybase Technical Support, to diagnose and resolve Replication Server, Replication Server Manager, or Log Transfer Manager (LTM) problems.
The directory structure listed in this section is a
partial directory structure. Your actual directory structure may
differ depending on the components you choose to install.
