To allow you to install SDK or Open Server 15.0 in a different directory but on the same machine as a pre-15.0 Adaptive Server installation, and to prevent the previous version from being affected, perform these steps:
Shut down Adaptive Server:
Use isql to log in to an Adaptive Server with System Administrator privileges:
isql -Usa -Ppassword -Sserver_name
Enter the following:
1> shutdown
2> go
Complete the SDK or Open Server installation as documented in the following installation sections.
Edit the SYBASE.csh or SYBASE.sh script file to comment out the pre-15.0 SDK and Open Server environment information.
Start Adaptive Server at the command line using the RUN_server_name file that contains information required to restart the server:
$SYBASE/$SYBASE_ASE/install/startserver [-f RUN_server_name file]
For more information about starting and stopping Adaptive Server, see the Adaptive Server Enterprise Configuration Guide for UNIX.
