SYSCS_UTIL.SYSCS_BACKUP_DATABASE_NOWAIT system procedure

If there are any transactions in progress with unlogged operations at the start of the backup, the SYSCS_UTIL.SYSCS_BACKUP_DATABASE_NOWAIT system procedure returns an error immediately, instead of waiting for those transactions to complete.

Syntax

SYSCS_UTIL.SYSCS_BACKUP_DATABASE_NOWAIT(IN BACKUPDIR VARCHAR()) 

No result is returned from the procedure.

BACKUPDIR

An input argument of type VARCHAR(32672) that specifies the path to a directory, where the backup should be stored. Relative paths are resolved based on the current user directory, user.dir, of the JVM where the database backup is occurring. Relative paths are not resolved based on the derby home directory. To avoid confusion, use the absolute path.

Execute privileges

If authentication and SQL authorization are both enabled, only the database owner has execute privileges on this procedure by default. See "Configuring user authentication" and "Configuring user authorization" in the Derby Security Guide for more information. The database owner can grant access to other users.

JDBC example

The following example backs up the database to the c:/backupdir directory:

CallableStatement cs = conn.prepareCall
("CALL SYSCS_UTIL.SYSCS_BACKUP_DATABASE_NOWAIT(?)");
cs.setString(1, "c:/backupdir");
cs.execute();
cs.close();

SQL example

The following example backs up the database to the c:/backupdir directory:

CALL SYSCS_UTIL.SYSCS_BACKUP_DATABASE_NOWAIT('c:/backupdir');
