Upgrade from version 15.5 to version 15.6 using the existing version 15.5 directories. You need not upgrade the RSSD, ERSSD, and user databases.
- Shut down Replication Server 15.5.
See Replication Server Configuration Guide for UNIX > Start or Stop a Replication Server > Stopping a Replication Server Using isql.
- Back up the entire set of files and directories under
$SYBASE.
Note: Keep this backup in case you need to downgrade from Replication Server version 15.6 to version 15.5.
- Use the Replication Server 15.6 Installation Guide for UNIX to install Replication Server 15.6 into the existing version 15.5 directories under $SYBASE.
Note: Do not install the SAMPLE_RS sample Replication Server from version 15.6 if you are using the SAMPLE_RS from version 15.5.
The installation process:
- Updates all subdirectories of $SYBASE that share directory names in both version 15.5 and 15.6
- Backs up existing SYBASE.* files, where * can be .env, .sh, or .csh, by adding a "save" suffix to the file. For example, Sybase.env is backed up as Sybase.env.save
- Copy the files that you backed up in step 2 such as, the interfaces file, resource files, .cfg files, the run_repservername runserver files, and ERSSD files, to the same directories which now contain Replication Server 15.6 files.
Copy any other files that were added or changed after installation to the corresponding directories. If you use an ERSSD, copy the dbfile, translog, errorlog, and backup directories to the corresponding locations. If you use SAMPLE_RS, copy all files and directories under $SYBASE/REP-15_5/samp_repserver to the corresponding locations.
- Set the relevant environment variables in the SYBASE.env file in the Replication Server 15.6 installation directory.
See Replication Server Installation Guide for UNIX > Postinstallation Tasks > Environment Variables on UNIX.
- Change the runserver file you copied from the backup to use the Replication Server 15.6 executable, and then start Replication Server.
See Replication Server Configuration Guide for UNIX > Start or Stop a Replication Server > Starting a Replication Server Using the Runserver File.
