When you install Sybase software, the software creates a system
administrator account called "sa," which can use any database on Adaptive Server, including
master, with full privileges.
Immediately after a new installation, the default password
is set to NULL, and Adaptive Server asks you to set a password for "sa." For security
purposes, assign a password to "sa" before using Adaptive Server in a production
environment, you cannot use a NULL password for "sa."
Log in to Adaptive Server as "sa" and set a password: $SYBASE/$SYBASE_OCS/bin/isql -Usa -P -Sserver_name
1> sp_password default, new_password
2> go
where:
-
default – is the non-null
password.
-
new_password – is the password that
you are assigning to the "sa" account.
For the greatest security, SAP recommends that you
create a password of at least six characters, with a combination of letters
and numbers.
