The end of Sybase

It is with sadness that I had to turn off the last Sybase Instance we had running. Our last ASE server quietly shutdown on an Amazon EC2 server on Tuesday the 20th of December, never to boot again.

In all truth both Sybase instances were developer installs operating as production systems. Our two instances, operating with the 25 user limit that each was restricted to, was barely able to operate the system. But the Sybase Licensing was too archaic and inflexible to continue operating it as a small business. Thus the economics forced us to convert to MySQL.

If it hadn’t been for the previous management, who in some delusion of saving money, refused to pay the datacenter bill, forcing us to move the Sybase instances out into the Amazon cloud (EC2) in the first place we would probably have been on MySQL sooner, as that was the plan.

But the sadness remains, Sybase as a technology proved again that it would run, and run reliably, on just about any hardware, even when it was virtual, and NOT meeting the specified certified, requirements of operation. Which can’t be said for the Amazon RDS version of MySQL, which crashed spontaneously while applying an index on our live production database without warning. This having happened after weeks of testing and trial runs at operating the system on it. The only defense, the RDS instance rebooted and was available without data loss, in less time than a Sybase HA switchover would have taken, a system this production system was developed from.

So we are up in MySQL and I am now a MySQL DBA exclusively, after spending the last 25 years as a Sybase DBA and evangelist. The decision now has to be rather to remain so, or find another place of employment where Sybase remains. Those are becoming more and more rare. Maybe I should takeup MongoDB to stay at the cutting edge.

A Cloud based Sybase

Over the past week I found myself in a situation as follows, during a migration, conversion from a Sybase Production server to a MySQL based version, I was required to ‘expedite’ a Sybase 15 ASE installation into an Amazon (EC2) instance, The Cloud!

The company has been in the position of seeking less expensive IT infrastructure over the past few years, moving from Sun Enterprise servers with ASE clustering to commodity Intel based Redhat Sybase servers with poor mans replication. The final goal became a decision to convert the expensive Sybase ASE (read inflexible licensing), to MySQL, and generally into the Amazon RDS (cloud).

The move of a Sybase ASE into the Cloud was the result of an urgent desire to terminate a data-center contract early by management. The shrinking time line for the conversion of the Sybase schema to MySQL could not be guaranteed so a Plan B had to be created. Hence, the Cloud based Sybase production edition of a production server.

To my surprise, it works! after a bit of twisting, the Redhat ASE developer installation came off more or less just like any other Sybase install. There are irregularities from a normal Linux install, but functional. Being a bit of a spindle jockey, I was surprised (happily) at the overall performance of the storage systems of the EC2 instance. And the production server is now operating in the instance. (having previously moved the app and web servers into the EC2)

This post needing a point to make, is this, while working this issue, I did considerable Googling for anyone using Sybase ASE in the cloud, and nothing! or nearly nothing. What I did find first, a press release from Sybase corporate that they were now in the Amazon Cloud, dated in 2009, and not a peep since. Nothing, no product, no advertising, no options. What a missed opportunity, it’s now easy to see why Sybase has been loosing so much market to a ‘free’ RDBMS like MySQL.
