Is it necessary to reinstall the Sybase database and the N2000 BMS after reinstalling Solaris OS on the SUN server?
No, not really.
If Solaris OS and the applications (the Sybase and the N2000 BMS) are installed in different disks, you need not to reinstall the applications after reinstalling Solaris OS. But you need to set the system parameters. Otherwise, the N2000 BMS cannot be started normally. After reinstalling Solaris OS, do as follows:
1. Modify the /etc/sytem file according to the operation manual. For example, set the shared memory or the descriptor of the process file.
2. Set the environment variable of the Sybase database. That is, add the following three lines to the end of the /etc/sytem file.
3. Create user n2kuser and download the .profile file under directory /n2kuser from another server. The .profile file is an environment variable for running the N2000 BMS. After executing the .profile file, you can start the N2000 BMS.
4. Copy the /etc/rc3.d/S99n2000sys file from another server to the directory of the SUN server. The /etc/rc3.d/S99n2000sys file is configured with the function that the Sybase and the N2000 BMS run automatically when Solaris OS is started.
