Post-upgrade tasks

In pre-12.5 Adaptive Server, it meant all the memory left after allocating memory for other configurations, procedures, and user-defined named caches. In Adaptive Server 12.5.x and later, it means a default value of 8MB.

During the upgrade process, Adaptive Server ensures that the default data cache size remains the same. Therefore, during the pre-upgrade process, the size of the default data cache is obtained and written to the configuration file as an absolute value, not as “DEFAULT”. This enables Adaptive Server to have the same default data cache size as before the upgrade. If this size is less than the default size of default data cache of 8MB, then Adaptive Server allocates a default data cache of size 8MB.

8For information about upgrading compiled objects, see “Upgrading compiled objects with dbcc upgrade_object” on page 109.

9If you used two-phase commit in 11.9.x, run the script to install the two-phase commit tables:

isql -Usa -Psa_password -Sserver_name

-i%SYBASE%\%SYBASE_ASE%\scripts\instcomm

You do not need to run this script if you do not use two-phase commit.

Reenabling Replication Server

If you disabled replication before the upgrade, you must reenable replication. To do so, first remove any older format log records from your database, and then reenable replication.

Removing old log records

Use the dump tran command to dump the database and transaction logs to remove the older format log records from your database. This prevents Replication Server from accessing the pre-upgrade portion of the transaction logs.

For example, to dump the sales database:

1> use master 2> go

1> dump database sales to "\\.\TAPE0"

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.
