In-Memory Databases vs Intel NVMe NUMA

By | Blog, Database Technology Trends, SAP HANA, Sybase | No Comments
For the past few years, the hot topic for database vendors was the in-memory database. The general belief was and maybe still is, that server memory is getting cheaper and density will continuously improve. For the most part, this has been the case, maybe not as extreme as predicted. However, the data storage needs for databases increased at a much faster pace during the same time, which created another problem. Going beyond 1TB of memory in a single server will quickly become very expensive. A 1TB database used to be called very large. This attribute is now applied to the 5-10 TB databases servers. In-memory databases are needed where read and write performance are equally important. Traditional databases improve read performance by caching data in memory, but there is no way to improve write performance. To be ACID (Atomic, Consistent, Isolated and Durable) compliant, data must be written to persistent storage. An in-memory database achieves this by writing every transaction in parallel to a high-performance storage. In many cases this is a flash drive on the PCI bus or a SSD drive. But every write action must be stored away from Memory (RAM) to be ACID compliant. There are many (more…)

SAP ASE Edge Edition

By | Preserved Content Pages | No Comments
This might be the biggest announcement from SAP you never heard of. After dropping the name Sybase from its product names last year, SAP is quietly reshaping its database platform offerings. And I mean this in a good way. Under the Sybase name there were 2 ASE products; Sybase ASE Enterprise Edition (EE) and Sybase ASE Small Business Edition (SBE). The Sybase ASE EE product was and still is the flagship and the most commonly known edition of Sybase. But it came with a hefty price ticket. To offer a Sybase ASE database server to the SMB market space, Sybase created ASE SBE, limited to 2 CPU sockets and 8 engines on a physical server, at a very low price. The server virtualization revolution has dramatically changed the server landscape and database servers made their transitions to the new world. The majority of newly deployed database servers are virtualized, either on premise or in the cloud. The Sybase ASE EE 15.7 database server enabled Sybase clients to make the move to the virtual servers with the introduction of the threaded kernel model. SAP ASE EE 16 continued the optimization for virtual servers and offers one of the most advanced database (more…)

Upgrade Sybase ASE to Sybase ASE Cluster Edition – Step by Step

By | Sybase Tips, Technology Tips & Tricks | No Comments

Install the Sybase ASE Cluster Edition Software

Shared Installation

With the new Sybase ASE 15.5 version, you have to option to install the software either as shared installation or private installation. If you use the shared installation, you need to have access to a shared filesystem that is accessible from every node in the cluster. Although the shared installation is more convenient, it presents other risks like a single point of failure if the shared filesystem goes offline.

Private Installation

The private installation provides a dependency separation between nodes for added stability and protection. The private installation installs the Sybase software on each node, and does not require a shared filesystem. You need to maintain a strict file structure and placement discipline, because every node must access the software identically.

Pre-Upgrade Steps

Once you completed the prerequisites, you need to shift your focus to preparing the databases, and the database server.

  1. If you are upgrading Adaptive Server, the previously installed version of the server must be running. If you are upgrading Backup Server, Historical Server, Monitor Server, or XP Server, those servers must not be running.
  2. Stored procedure text in the syscomments table is required for the upgrade. If you deleted the text, you must add it back again.Note: As a best practice: if you don’t want to display the text, hide it by using the sp_hide_text stored procedure instead of deleting it.
  3. Resolve reserved words using quoted identifiers. This is a simple check by installing the upgrade package and then executing sp_checkreswords.Caution: This step is simple enough, but if omitted, can lead to serious issues during the upgrade process.
