HP NonStop technology drives many of the world’s most powerful business systems, hosting hundreds, even thousands, of transactions per second. Some transactions may be small, some very large—and some may move across several systems before completing. These enterprise applications depend on the legendary fault tolerance and data integrity delivered on HP Integrity Nonstop servers. A fundamental component of the engine powering this technology for business is the NonStop Transaction Management Facility (NonStop TMF): It ensures the consistency of a database and boosts system performance.
But not all applications are written to harness the power of NonStop TMF; many businesses employ the power of NonStop AutoTMF—to simply and completely protect a previously “unaudited” database. By installing NonStop AutoTMF you can rest assured that, without additional programming, your application is made continuously available.
New user-friendly enhancements
A number of user-friendly enhancements have been included in the latest improvements to NonStop AutoTMF Version 1.0 (Update 8) for Integrity NonStop and Nonstop S-series servers.
- AutoCommit feature enabled by default, with optional timer settings, for a safety net against loss of data
- New NOWARNLONGTX command suppresses periodic event message warnings notifying the operator of a long-running transaction
- New ENV command displays the transid of the current transaction
- New OBEYFORM option for INFO GLOBALS and INFO LOCALS allows full capture and repeat of environment configuration settings
The AutoCommit feature in NonStop AutoTMF is now enabled by default, with optional timer settings. This feature acts as a safety net, forcing a long-running automatic transaction to commit just before it reaches the NonStop TMF auto abort limit, thus preventing data loss.
A new NOWARNLONGTX command suppresses periodic event message warnings that notify the operator of a long-running transaction. Normally, if NonStop AutoTMF detects that an automatic transaction has been running for more than five minutes, it logs a message to the Event Management Service (EMS). The warning is repeated every five minutes until the transaction commits. Note that NOWARNLONGTX should be used with caution, and only if the cause of the commit delay is well understood.
A new OBEYFORM option for the INFO GLOBALS and INFO LOCALS commands produces the list of commands that were used to change default values of global parameters. Used in conjunction with other INFO commands, this feature allows full capture and repeat of environment configuration settings.
In addition, Update 8 includes a few quality improvements and better displays product license information to more clearly show product licensing status.
