Problem Converting standby database from snapshot to physical

Question

Any help willl be greatly appreciated...
I am trying to convert a standby database that is in "snapshot" mode back to "physical" standby and I am encountering problems in the process from the "DGMGRL" command line.
Both instances are on the same physical machine. Everything was working fine untill I tried to change the db from snapshot to physical. The DGMGRL starts the conversion process and is able to shutdown but when trying to restart the instance is fails and reports that the service is not defined.
Here is the issue I am facing:

Answer 1

Thanks for the response.
So, here is the status now....with a little background...
After my original post, I started to read the manuals and I found the sql command to convert the database back from snapshot to physical standby (sb).
That worked fine and I had my snapshot sb back to physical sb.
So when you posted the suggestion, I already had my db in physical sb mode. I said no problem, I will convert it back to snapshot and then back again using dgmgrl instead of sql+
Well here is how my listener is configured now.
SID_LIST_I11G1 =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = I11G1.MHOST)
(ORACLE_HOME = c:\app\mmj\product\11.1.0\db_1)
(SID_NAME = I11G1)
(SID_DESC =
(GLOBAL_DBNAME = I11G1SB.MHOST)
(ORACLE_HOME = c:\app\mmj\product\11.1.0\db_1)
(SID_NAME = I11G1SB)
(SID_DESC =
(GLOBAL_DBNAME = I11G1SB_DGMGRL)
(ORACLE_HOME = c:\app\mmj\product\11.1.0\db_1)
(SID_NAME = I11G1SB)
Then using dgmgrl I tried to change the db from p-sb to s-sb and the results are not good....

Not sure if the following (notice the typo in the service name) in the parameter (log_archive_dest_2) definition on the standby d/b has anything to do with this. I did not get this error when I initially converted to s-sb.
also I checked all my session notes, I did not type the command to set this parameter on the standby d/b and so it was not a typo on my part. However, it seems to have come from the rman script supplied with the obe. This script is supposed to clone the primary d/b to a standby db and in the process replace the string /i11g1/ with /i11g1sb/.

Given all this, the archive logs seem to be shipping correctly to the sby d/b.

I am tempted to start all over again, but I'd rather use this opportunity to debug this issue (as a learning exercise). I can always start from scratch. That brings up another Q: What do I need to do to blow away all traces of the stand by database (including all the archive logs etc...) keeping my primary intact. I'd also like to blow away all snapshot and archive logs for the primary as well.
