Transaction Number Rollover Continued ...

In Volume 23 of the FairCom eNewsletter, we discussed six byte transaction numbers and how to take advantage of this vast volume of available numbers to greatly increase the life span of your active c-tree data files.

We mentioned that some transaction-intensive applications using older versions of c-tree have experienced exhausting these numbers. With faster and faster hardware, and greater volumes than ever, there are good reasons to migrate to c-tree Plus and c-tree Server V8.14.

Consider a moderately high volume application with 1000 transactions per second:

Transaction Number Limits

  • V6 supports around 1 billion transactions: 1000 tps for ~11.6 days.
  • V8 supports 70 x 1012: 1000 tps for ~2000 years.

FairCom has created a comprehensive white paper describing this limitation of four byte transaction numbers, how to recover when you exhaust your supply of numbers, and how to convert and take advantage of six byte transaction number support.

Migrate to 6-Byte Transaction #’s in 5 Easy Steps

  1. Relink all client applications with c-tree Plus V8 libraries.
  2. Install a new c-tree V8 Server or newer using recommended practices.
  3. Ensure ALL c-tree Server Transaction Logs (*.FCS) are removed.

    Warning: You will lose all User IDs and passwords when FAIRCOM.FCS is deleted. These can be recreated with the c-tree Server Administration utility, ctadmn.

  4. Ensure all data files have an extended header which allows huge file and six byte transaction numbers. V6 c-tree Plus data files may be converted using the c-tree Plus Conversion utility, ctcv67. Be sure to observe the note below concerning this standalone application.
  5. After starting the new c-tree Server, ensure ALL indices are rebuilt using the c-tree Server. Remember, existing indexes that have not had an appropriate extended header added will be rebuilt with the old four byte number support.

Note: You can use rebuild and other standalone programs linked with c-tree V8 as a single-user library, however be sure the 6 byte transaction number is activated with #define ctFeat6BT in your ctoptn.h file. It is off by default in this operational model.
