CHAPTER 5 Upgrading Adaptive Server

c Run the upgrade process.

Note Adaptive Server issues advisory warnings when configuration parameters are not set to the default. These do not require any action.

The preupgrade and upgrade utilities are internally called by syconfig.exe or sybatch.exe.

Each new version of Adaptive Server contains features that introduce new parameters, commands, reserved words, and so on. For this reason, preupgrade is for preparing the old server for upgrade.

syconfig.exe, sybatch.exe, or preupgrd.exe runs various checks to determine how much space you must add to the old server to successfully upgrade the old server to the new.

As part of the pre-upgrade tasks, syconfig.exe, sybatch.exe, or preupgrd.exe scans all databases and catalogs and determines how much free space is required to upgrade successfully. Essentially, syconfig.exe, or sybatch.exe searches for the largest catalog, then calculates the required free space by doubling the size of the largest catalog, and adding approximately 10 percent for logging the upgrade changes for each catalog.

During the pre-upgrade process, syconfig.exe, sybatch.exe, or preupgrd.exe returns informational messages as it checks the old server. You must fix all reported problems, and run syconfig.exe, sybatch.exe, or preupgrd.exe cleanly before beginning the upgrade process. Once the old server is eligible to be upgraded, syconfig.exe, sybatch.exe, or preupgrd.exe shuts down the old server, starts the new server against the existing databases, and begins the upgrade process.

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.
