CHAPTER 5 Upgrading Adaptive Server

5Check the procedure cache requirements.

Stored procedures, triggers, and other compiled objects require more memory to run than older versions. The memory required to run a stored procedure increased by 20 percent between versions 10.x and 11.5. Adaptive Server 12.5.x needs approximately 4 percent more procedure cache than version 11.5 for the server to maintain the same performance.

You may increase the procedure cache size during runtime, using

sp_configure. You can use the verify option in sp_configure to verify any changes you make to the configuration file without having to restart Adaptive Server. The syntax is:

sp_configure "configuration file", 0, "verify", "full_path_to_file"

For example:

sp_configure "configuration file", 0, "verify", "C:\Sybase\ASE125.cfg"

For more information about sp_configure and sp_sysmon, see the Reference Manual and the Performance and Tuning Guide. For more information about configuring memory, see the System Administration Guide.

6Verify data cache allocation after upgrading. This section is for information only. Adaptive Server ensures that all the data cache sizes after upgrading are the same as before upgrade.

In pre-12.5 versions of Adaptive Server, the default data cache available depended on the amount of memory available to Adaptive Server. If the default data cache was set to 2MB, Adaptive Server allocated 2MB to the default data cache. If, after memory was allocated to all user-defined data caches and to the procedure cache, there was more memory available, that memory was allocated to the default data cache. However, if there was not enough memory available for Adaptive Server to set up the user-defined caches and the procedure cache, then memory was taken from the default data cache regardless of the designated configuration parameter.

Therefore, it was possible to set default data cache to the default value and have all remaining available memory allocated to the default data cache.

Adaptive Server 12.5.x and later treats the default data cache size as an absolute value and sets it in the config file. The string DEFAULT in the config file has a different meaning for default data cache size in Adaptive Server 12.5.x and later.

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.
