SYSCS_UTIL.SYSCS_BACKUP_DATABASE_AND_ENABLE_LOG_ARCHIVE_MODE_NOWAIT system procedure

The SYSCS_UTIL.SYSCS_BACKUP_DATABASE_AND_ENABLE_LOG_ARCHIVE_MODE_NOWAIT system procedure backs up the database to a specified backup directory and enables the database for log archive mode. This procedure returns an error if there are any transactions in progress that have unlogged operations at the start of the backup, instead of waiting for those transactions to complete.

Syntax

SYSCS_UTIL.SYSCS_BACKUP_DATABASE_AND_ENABLE_LOG_ARCHIVE_MODE_NOWAIT
(IN BACKUPDIR VARCHAR(32672),
IN SMALLINT DELETE_ARCHIVED_LOG_FILES)

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.

DELETE_ARCHIVED_LOG_FILES

If the input parameter value for the DELETE_ARCHIVED_LOG_FILES parameter is a non-zero value, online archived log files that were created before this backup will be deleted. The log files are deleted only after a successful backup.

Execute privileges

If authentication and SQL authorization are both enabled, only the database owner has execute privileges on this procedure by default. See "Enabling user authentication" and "Setting the SQL standard authorization mode" in the Derby Developer's 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 and enables log archive mode:

CallableStatement cs = conn.prepareCall
("CALL SYSCS_UTIL.SYSCS_BACKUP_DATABASE_AND_ENABLE_LOG_ARCHIVE_MODE_NOWAIT(?, ?)");
cs.setString(1, "c:/backupdir"); 
cs.setInt(2, 0);
cs.execute();

SQL examples

The following example backs up the database to the c:/backupdir directory, enables log archive mode, and does not delete any existing online archived log files:

SYSCS_UTIL.SYSCS_BACKUP_DATABASE_AND_ENABLE_LOG_ARCHIVE_MODE_NOWAIT('c:/backupdir', 0)

SYSCS_UTIL.SYSCS_BACKUP_DATABASE_AND_ENABLE_LOG_ARCHIVE_MODE_NOWAIT('c:/backupdir', 1)
