Testing Data Guard [message #558524]

I have been trying to setup a test data guard environment to become more familiar with it, but so far I have been unsuccessful. I have been using the guide located at docs.oracle.com/cd/B19306_01/server.102/b14239/create_ps.htm for the steps I am following.

Right now, I'm just trying to get a non-production physical standby configured and working. I have kept kind of a running summary of the commands I have run so far, and would like to paste them below and see if I am missing anything obvious. If necessary, I can post a pfile from both servers to see if maybe I am missing something in the parameters.

I have verified that both instances can be connected to via sqlplus from the opposite server.

Any help or guidance is appreciated.

ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=standby LGWR ASYNC VALID_FOR=(ONlINE_LOGFILES,PRIMARY_ROLES)

You have a typo here, according to the docs this should read

ONLINE_LOGFILES,PRIMARY_ROLE

I've never tried with PRIMARY_ROLES. Do please use [code] tags described here How to use [code] tags and make your code easier to read it makes such mistakes much easier to see.
Probably, your remote archive destination is in error state. Check it with

select dest_name,status,error from v$archive_dest;

and correct it with

alter system set log_archive_dest_state_2=enable;

No criticism taken, as far as I'm concerned any help or advice I receive is welcome. Here's some info I left out from my initial post according to the faq:

Database version:11.2.0.0 (plain vanilla r2)

I think I know what to do after reviewing the alert logs from the two servers. I am working on recreating the password files for the two instances. I know that I configured the passwords to be the same, but for some reason this is what I am getting:

Also, I verified that log_archive_dest_2 and _1 are enabled on both systems
standby:

NAME                                 TYPE        VALUE

log_archive_dest_state_1             string      enable

------------------------------------ ----------- ------------------------------
log_archive_dest_state_2             string      enable

primary:

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest_state_1             string      enable

use the "orapwd" utility to create the password file on the PRIMARY & then do OS file copy to place it on STANDBY

Instead of using orapwd, I just copied the existing pwdfile from primary to standby and restarted the primary then the secondary instance.

Thanks to all for assistance! Next step, try to convert to logical standby Smile
