I'm trying to do TSPITR (on 10g for now) in its simplest form, nothing fancy at all but no recovery catalog.
I did 'backup tablespace blah'
then I noted the current_scn and did some sql stuff
then I did 'recover tablespace blah until scn x auxiliary destination 'c:\eek'

The auxiliary instance got created and started but then it said

RMAN-03002: failure of recover command at 06/26/2006 11:10:09
RMAN-03015: error occurred in stored script Memory Script
RMAN-06026: some targets not found - aborting restore
RMAN-06024: no backup or copy of the control file found to restore

I also tried instead of auxiliary destination using set newname but I got the same error.

What is it looking for that it can't find?
What piece of the puzzle am I missing to get it to work??

please help - john.todd@ca.com

Very generic error.
Did you also include the current control file in backup? ( or did configure control file autobackup?)
This posting will give some basic steps (though outdated, concepts still apply).

> include control file in backup?
No I didn't, is the syntax as simple as
backup tablespace blah plus controlfile?

Ok, got much farther this time but I'm not there yet, still need a little help.

The latest scoop is it gets all the way to the export phase and fails on a 29308, please help me figure out what I'm missing. Thanks.
here are the details:

backup tablespace SYSTEM, UNDOTBS1, MY_DATA include current controlfile;
select current_scn from v$Database
	scn = 1415638

// do sql operations

Then I attempted to recover to scn 1415638 (the point before I did the 
sql operations that mucked up the database)

Seems like an integrity/Dependency problem.
The tablespace you are restoring has a depedency in some other tablespace ( Like a table SOMETABLE in MY_DATA tablespace has an index SOMEINDEX in MY_INDEX tablespace).
Check that out.

dbadmin@9i > get ts
  1  select obj1_name,ts1_name,obj2_name,ts2_name from sys.ts_pitr_check
  2* where obj1_owner='DBADMIN'
dbadmin@9i > /

OBJ1_NAME  TS1_NAME   OBJ2_NAME  TS2_NAME
---------- ---------- ---------- ----------
EMP        USERS      MYINDEX    TOOLS


And Please format your code using CODE tags.

Yes, I have a tablespace called MY_INDEX (ok not really, but you get the idea).
If I include MY_DATA and MY_INDEX on the same recover line, that might work?

What does the documentation say?
Regarding dependencies,
http://download-east.oracle.com/docs/cd/B19306_01/backup.102/b14191/rcmtspit002.htm#sthref774
Regarding more than 1 tablespace to restore
http://download-east.oracle.com/docs/cd/B19306_01/backup.102/b14191/rcmtspit003.htm#sthref777


You can use

Ok, thank you for your great help getting TSPITR to work with 10g, now I need it to work with 9i and it seems much more complicated. I apparently need to manage the auxiliary instance manually. I seem to be fighting with TNS issues trying to do that. What are the very basics of creating an instance in a
non-gui way that I can use with TSPITR, I also want to avoid manually editing .ora files because the goal here is to automate the process. I found the oradim utility but that seems to be only part of the picture.
I know I'm asking a big question here, but any help would be appreciated.

Thanks.

The concepts stay the same.
Very subtle difference.

http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96566/rcmdupdb.htm#441628

>>What are the very basics of creating an instance in a
>>non-gui way that I can use with TSPITR
You can manually create the database
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96521/create.htm#1000691
Oradim is to create a service for in windows environment.
>>I also want to avoid manually editing .ora
You are going to do this only once.

>>the goal here is to automate the process.
Can be done. Works like an angel. I have automated 9i rman duplication. After 3+ years
still runs without a glitch.

>>I know I'm asking a big question here, but any help would be appreciated.
We (here at orafaq and elsewhere) stress this again and again.

Before posting, Please search the google/this site / documentation . Most of the questions are already answered in one form or other.

> I have automated 9i rman duplication
Do you have scripts that you could share with me, or would there be too many site specific issues involved there...i.e. only works if my environment is configured just-so?

I'm running into a problem where it says the datafile is already recovered...here's the scoop on that

oradim -new -sid aux
set ORACLE_SID aux
Sqlplus> startup nomount
<OK>

set ORACLE_SID ora9
rman target="/" cmdfile="do_backup"
sqlplus> select dbms_flashback.get_system_change_number()
<Remember that>

// do tablespace mucking stuff

set ORACLE_SID aux
rman> connect target /@ora9
<connected to target database ora9 ID=x>
connect auxiliary /
<connected to auxiliary database nomount>
restore tablespace my_tablespace until scn X

using target database controlfile instead of recovery catalog
allocated channel: ORA_DISK_1

skipping datafile 11; already restored to file C:\ORACLE\ORADATA\MYPATH
restore not done; all files readonly, offline, or already restored
Finished restore at 30-JUN-06


What am I doing wrong here?

I use recovery catalog and it is very site specific (even if it is not, i cannot post 'em here).
There are lot of pointers here in this site/google/metalink and ofcourse documentation.
Oracle documentation is your best available resource.
>>restore not done; all files readonly, offline, or already restored
means, there is nothing to restore. All the files are already synched.
