Open or Close a Database

Options

ttAdmin has these options for opening or closing a database:

Option Description

-close

Closes a database to user connections.

When a database is closed to user connections, new connection attempts will fail, but existing connections are unaffected.

-connStr connection_string

An ODBC connection string that specifies a database location, driver, and optionally other connection attribute settings.

DSN

An ODBC data source name of the database to be administered.

-open

Opens a database to user connections.

A database is open to user connections by default upon creation.

-ramLoad

Valid only when -ramPolicy is manual. Causes the database to be loaded into RAM.

Examples

To open the database1 DSN:

% ttAdmin -open database1

To load and open the database1 DSN from an unloaded and closed state:

% ttAdmin -ramLoad -open database1

To close the database1 DSN:

% ttAdmin -close database1

To load and close the database1 DSN from an unloaded and open state:

% ttAdmin -ramLoad -close database1

Notes

A database remains closed or open to user connections regardless of its loaded state or RAM policy, unless its closed or open state is modified through ttAdmin or other utilities like ttRestore or ttRepAdmin.

If the -open or -close options are used in conjunction with any option other than -ramLoad, ttAdmin returns an error.

Trying to close a closed database or open an open database returns an error.
