However, it also means that, if I have direct access to a database file, I can copy that file from a server where I may not know the SYSDBA password onto a different server where I

Different tasks may be performed in each of the modes, as illustrated below: • An interactive session be used interactively to: ◦ Create, update, query, and drop data or metadata. ◦ Input a script file containing a batch of SQL statements in sequence without prompting. ◦ Add and modify data. ◦ Grant to the operating system. • In a non-interactive session, the user employs a shell script or batch file to perform database functions.  Because other applications in the Linux environment, for example

Coming up in the remainder of this manual, we will discuss the following: • Command line options for the gfix database utility. • Shadow file handling. • Cache and buffer handling. • Transaction management. • Cache management. • Starting 7 usage: gfix [options] plausible options are: -ac(tivate_shadow) activate shadow file for database usage -at(tach) shutdown new database attachments -b(uffers)
