You could use DBUtil option to create the securestore.enc file.
Navigate to the following location where DBUtil is available:
On Windows
<install_location>\Arcot Systems\tools\win
On UNIX-based Platforms
<install_location>/arcot/tools/<platform_name>
-init
Creates a securestore.enc with the new master key that you specify, as discussed in "Updating the Master Key".
Syntax:
dbutil -init key
For example:
dbutil -init MasterKeyNew
dbutil -init RiskFortDatabaseMKNew
Important! This command succeeds only if there is no securestore.enc in the conf directory.
To insert the supplied database values in securestore.enc, use the following commands:
(For software mode) dbutil -pi <dbUser> <dbPassword>
