Creating a sybase account provides consistent ownership and privileges for all installation, configuration, and upgrade tasks.
The sybase user must have permission privileges from the top (or root) of the disk partition or operating system directory down to the specific physical device or operating system file. If you have already installed other Sybase software, the sybase user may already exist. If so, verify that you can log in to the machine using this account.
If there is no sybase account on your system, see your operating system documentation for instructions about creating new user accounts.
