CHAPTER 5 Upgrading Adaptive Server

1In isql, use alter database to increase the size of the master database. For example:

1> use master 2> go

1> alter database master on master=x 2> go

This example increases the size of the master database; x is the number of megabytes of space added to the existing database size.

2Repeat this step to increase the size of each of the tempdb and the model databases. For example:

1> alter database tempdb on master=x 2> go

1> alter database model on master=x 2> go

Note The model database cannot be larger than the tempdb. If your changes cause the model database to be larger than the tempdb, then you must first increase the size of tempdb, before increasing the size of the model database.

3Verify the size of each database. Enter the following, where database_name is the name of the system database you are checking:

1> sp_helpdb database_name

2> go

Create a sybsystemdb database

In version 11.9.x, the sybsystemdb database was required only for servers using two-phase commit transactions. Beginning with version 12.0, all servers must have a sybsystemdb database. Adaptive Server uses this database for tracking transactions and during recovery. In addition, it is used for applications using two-phase commit and Distributed Transaction Management (DTM).

If you have a sybsystemdb database

If you have a sybsystemdb and the database is at least 4MB, you do not need to make any changes. If the database is smaller than 4MB, increase the size with alter database.

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.
