Sybase Adaptive Server Enterprise is a strong data management platform for high-performance business applications. Sybase ASE is a functional, enterprise-class RDBMS that is especially good at handling OLTP workloads and is used widely in financial, E-commerce, and other technology areas. The Sybase ASE platform contains many standard components, such as the Adaptive Server, Monitor Server, and Backup Server, as well as other plug-in components.
The Monitor Server is a separate server from the database server that displays the Adaptive Server. The Monitor Server can support real-time or historical data to client applications. The Backup Server is an open server-based application that handles all database backups (dump) and restores (load) the operations for the Adaptive Server. In Sybase ASE, a checkpoint process is an additional part of database logging and recovery in Sybase and other database engines. To enhance this, we need to understand the logging and recovery process in Sybase.
SPS for Linux Sybase ASE Recovery Kit
The SIOS Protection Suite for Linux Sybase ASE Recovery Kit will support SPS resource protection for the Sybase ASE components like the Adaptive Server, Monitor Server, and Backup Server. Sybase ASE creates backup information to backup error log which is, by default, in the ASE’s install directory. You can create your table and use the ASE scheduler to start your backup. The SIOS Protection Suite (SPS) for Linux Sybase ASE Recovery Kit supports a mechanism for protecting Sybase ASE Server instances within SPS. The Sybase ASE software, LifeKeeper Core and Sybase ASE Recovery Kit are installed on multiple servers in a cluster.
Once the Sybase ASE Server instance is under SPS protection, clients connect to the database with the help of SPS protected IP address. The SPS protected IP address must be built separately before the creation of the Sybase ASE resource hierarchy. The Sybase ASE resource hierarchy creation will write the dependency between the parent Sybase ASE resource case, and the child IP address resource. If the Sybase ASE Server case fails, SPS will first attempt to recover it on the local server. If the local recovery fails, then SPS will failover to a backup server.
