Suspending transaction processing and replication activities

•Disabling the log truncation point.

After upgrading to version 15.0, complete the post-upgrade tasks to re-enable database replications functions.

For more information, see the Replication Server Reference Manual and the

Replication Server System Administration Guide.

Warning! As a safeguard, perform a dump database and a dump transaction before executing the procedures in the following sections.

To determine whether your existing server contains replicated databases:

1Use isql to connect to the Server you are upgrading.

2Run the following command in each database (including system databases):

1> dbcc gettrunc 2> go

3If the command returns “1” for “ltm_trunc_state” in any database, replication is enabled in that database.

Suspending transaction processing and replication activities

To suspend replication of and transaction activity in the databases:

1Verify that subscriptions that are being created by the create subscription command, with primary data in the databases being upgraded, have reached the “valid” state at the primary Replication Server before you begin the upgrade. Use the check subscription command to find the “valid” state.

Defer the upgrade process while the subscriptions are being created so that Replication Server does not interfere by attempting to access the database being upgraded.

Make sure that no users create subscriptions for data in the database you are upgrading until the upgrade procedure is finished.

2Execute rs_helproute in each Replication Server System Database (RSSD) being upgraded.

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.
