hi, there:
i want to know some api or tech info of informix redo log. pls help....

Can you be a little more specific.

I'm pretty sure there is no API, to make connections or something to it. Complete informix internals, only onlog can be used to monitor it.

Here some general info:
- Onlog is the utility to search/browse the logical logs
- Are used for rollbacks, rollforward, replication, crash recovery
- More info can be found in the manuals

Sorry for the brief answer,

Rob Prop

do u konw the structure of logic log? can i write any api to operate on it?

No, sorry the structure is informix internal. It si also version dependent. I don't knwo what kind of API you're trying to built. But writing to it is surely unsupported and also not recommended, 1 mistake and a server crash will be the next thing. Recovery? -> restore.

Reading with an API??, why not use onlog for that and use the output of this.

Hope this helps,

Rob Prop
