Upgrading compiled objects with dbcc upgrade_object

Error reporting

To send all the output from dbcc upgrade_object to the window, a System Administrator can execute dbcc traceon(3604). Sybase recommends that you use this command if you think the output of error messages might overflow the error log.

Using database dumps in upgrades

Upgrading using dump and load

You can load pre-12.5 database dumps and transaction logs and upgrade the databases.

Some issues of which you should be aware:

•Upgrading requires space for copying data and logging changes to the system tables during the upgrade process. If the source database in the dump was nearly full, the upgrade process might fail due to insufficient space. While this is expected to be uncommon, you can use alter database to extend the free space in the event of insufficient-space errors.

•After reloading an older dump, run sp_checkreswords from the new installation on the loaded database to check for reserved words.

Upgrading compiled objects in database dumps

When you load a database dump that was created in an earlier version than the current Adaptive Server, you are not required to perform the pre-upgrade tasks before loading the dump. Therefore, you will not receive any notification if the compiled objects in your database dump are missing their source text. After loading a database dump, run sp_checksource to verify the existence of the source text for all compiled objects in the database. Then, you can allow the compiled objects to be upgraded as they are executed, or you can run dbcc upgrade_object to find potential problems and upgrade objects manually.

For information on using sp_checksource, see the Reference Manual:

Procedures.

15.0.2 specifications

Sybase 15.0.2, a product of the Sybase corporation (now SAP), is a relational database management system (RDBMS) that provides robust solutions for data management, security, and performance. This version builds upon its predecessors, offering improved features and enhancements that cater to both enterprises and developers.

One of the standout features of Sybase 15.0.2 is its advanced performance capabilities. The version introduces optimization enhancements such as the Query Optimizer, which is designed to ensure efficient execution of complex queries. This optimizer analyzes SQL statements and tables to choose the most efficient means of retrieval, thus reducing execution time and improving the overall performance of the database.

Sybase 15.0.2 supports improved scalability, allowing organizations to handle increased workloads without significant changes to their infrastructure. This scalability is crucial for businesses experiencing growth, as it ensures that performance remains consistent and reliable.

Another notable characteristic is the robust security architecture integrated within Sybase 15.0.2. The system includes features like data encryption, user authentication, and authorization mechanisms, making it suitable for environments that handle sensitive information. Database administrators can implement fine-grained access controls to manage user permissions effectively.

Moreover, Sybase 15.0.2 boasts support for a wide range of programming languages and frameworks. This versatility allows developers to build applications using their preferred tools, promoting productivity and ease of integration into existing systems. The database management system also supports various platforms, including Windows and UNIX, enabling diverse deployments across different environments.

In addition to these technological enhancements, Sybase 15.0.2 emphasizes data integrity through its robust transaction management system. It implements the ACID properties (Atomicity, Consistency, Isolation, Durability) to ensure that all database transactions are processed reliably, thereby maintaining the integrity of data even in high-transaction scenarios.

In conclusion, Sybase 15.0.2 is a feature-rich RDBMS that combines performance, scalability, security, and flexibility. Its advanced capabilities not only enhance data management for organizations but also provide a solid foundation for developers seeking to create efficient and secure applications. The improvements in this version make it a compelling choice for enterprises looking to optimize their database operations in an increasingly data-driven world.
