This document aims at showcasing the capabilities and usage of Oracle’s DBMS_APPLICATION_INFO built-in package. One very important use is to monitor the progress of loops to know exactly which record is being processed at a given moment.
SAP Sybase has developed a new, innovative and dynamic staging technology, allowing full use of the native, high-speed data load mechanism SAP Sybase IQ offers . . . Real Time Loading (RTL).
RTL addresses the need to have another system prepare the data for load by taking real time data movement from the source database, and applying staging technology to the data transfer in the background.
Up until now, the only option for loading data from an Online Transaction Processing (OLTP) database . . . airline reservation systems, financial transactions, etc., into a SAP Sybase IQ data warehouse was a so-called staging process. Staging means that the OLTP is isolated from the data warehouse loading process to ensure data integrity, due to the rapidly changing data content in the OLTP database systems.
Direct replication into SAP Sybase IQ was limited to low data movement environments. The reason lies in the fundamental differences on how SAP Sybase IQ processes data, and data movement strategies SAP Sybase Replication Server applies.
SAP Sybase IQ is a column vector database. Retrieving a single row requires assembling the row from each column component. This process makes row by row processing ineffective, and the so- called “trickle feed” loading of SAP Sybase IQ nearly impossible. The advantage of a column vector database is in the unmatched speed for complex data retrieval operations and data aggregation on huge data sets.

The Oracle to Sybase Migration Guide provides detailed information on migrating a database from Oracle® 9i, 10g and 11g to Sybase Adaptive Server® Enterprise (ASE). The processes and differences outlined in this guide will help you to manage the migration process, regardless the conversion tool you are using to perform the migration. The focus is on the Oracle to Sybase ASE migration and Oracle features like data replication or data warehousing are better utilized in other specialized Sybase products.
If not otherwise specified all stand-alone references to simply Sybase ASE or Adaptive Server are considered references to Sybase Adaptive Server® Enterprise.
