JP, Juan, and Prem,
Prem is correct. Standby is certainly a feature of SE, just not the
managed recovery and SQL*Net log shipping parts, which only come with
EE. Essentially, Standby Database features in SE is just like Standby
Database features from 7.3 through 8.0.
I have some shell scripts
track of log gaps
manually.

Hi!
I think archive log gap management is a new feature in 9i Data Guard. Check
9i's docs. You might have to build custom scripts for gap management in 8i.
Also, I recommend you to use documentation from authentic location,

SvrMgr process in a backgrounded script. Stopping the backgrounded script
is easy using the RECOVER CANCEL command from any other session...

I used to do this with a 7.3.4 instance on Unix, I had a shell script
that would run every x minutes, and would first check to see it if was
already running. If not, it would do the recover automatic. It would
fail when it ran out of archived logs to apply, but the cron would
restart it
nope its unix(solaris flavor).
thanks for the idea, thats probably what I'll do versus trying to setup
data guard on the nodes.

I got this error when I first set up my standby database. If you generate a

you created your standby control file has not been archived. If you issue

You need to recreate standby control file...

Quick question, long answer...
You are not only making sense, you have hit the primary issue with the
Oracle standby database directly on the head. With DataGuard in 9i
(or 8i on HP-UX or Solaris only), you can *try* to retrieve redo log
files. You could also do it manually - with any version.

There may be some solutions available at the hardware level as well..
For example-SRDF on an EMC cabinet... and define the online redo
logs/archive logs as part of the data transfer.. But there are performance
problems with that as well.
