Upgrade utility (dbupgrad)

Note

You cannot use the Upgrade utility (dbupgrad) to upgrade SQL Anywhere 9.0.2 and earlier databases to SQL Anywhere 12. To upgrade SQL Anywhere 9.0.2 and earlier databases to SQL Anywhere 12, you must rebuild the database by performing an unload and reload. See Upgrading SQL Anywhere.

Updates the system tables and views, adds new database options, and recreates all system stored procedures. Installs jConnect support and changing support for Java in the database.

Syntax

dbupgrad [ options ]

Option

Description

@data

Reads in options from the specified environment variable or configuration file. See Using configuration files.

If you want to protect passwords or other information in the configuration file, you can use the File Hiding utility to obfuscate the contents of the configuration file. See File Hiding utility (dbfhide).

-c "keyword=value; ..."

Specifies connection parameters. See Connection parameters.

The user ID must have DBA authority.

For example, the following command upgrades a database called sample12 and does not install jConnect support, connecting as user DBA with password sql:

dbupgrad -c "UID=DBA;PWD=sql;DBF=c:\sa12\sample12.db" -i

-i

Excludes jConnect metadata support. If you want to use the jConnect JDBC driver to access system catalog information, you should not use this option. You can still use jConnect when this option is specified, as long as you do not access system catalog information. If you want, you can add jConnect metadata support later using Sybase Central or the ALTER DATABASE UPGRADE statement. See Installing jConnect system objects into a database and ALTER DATABASE statement.

-o filename

Writes output messages to the specified file.

-q

Runs in quiet mode—messages and windows are not displayed.

Remarks

Caution

You should always back up your database files before upgrading. If you apply the upgrade to the existing files, then these files become unusable if the upgrade fails. For information about backing up your database, see Backup and data recovery.

The dbupgrad utility upgrades a database created with earlier versions of the software to enable features from the current version of the software. The earliest version that can be upgraded is SQL Anywhere 10.0.0. While later versions of the database server can run against databases that were created with earlier releases of the software, some of the features introduced since the version that created the database are unavailable unless the database is upgraded.

An error message is returned if you use the Upgrade utility to upgrade a database that is currently being mirrored.

Databases with materialized views

It is recommended that you refresh the materialized views in your database after upgrading the database. See Refresh manual views.

You can use the Upgrade utility to update the system tables and views, add new database options, restore database options, and recreate all system stored procedures, and install jConnect support and change support for Java in the database.

Not all features made available

Features that require a physical reorganization of the database file are not made available by dbupgrad. Such features include index enhancements and changes in data storage. To obtain the benefits of these enhancements, you must unload and reload your database. See Upgrading SQL Anywhere.

As new versions and software updates become available for SQL Anywhere, you can use the Upgrade utility to take advantage of the new features.

Upgrading a database does not require you to unload and reload your database.

If you want to use replication on an upgraded database, you must also archive your transaction log and start a new one on the upgraded database.

You can access the Upgrade utility in the following ways:

From Sybase Central, using the Upgrade Database Wizard.
From Interactive SQL, using the ALTER DATABASE UPGRADE statement. See ALTER DATABASE statement.
At a command prompt, using the dbupgrad command.

Exit codes are 0 (success) or non-zero (failure). See Software component exit codes.
