Logical standby rolling upgrade issue

Question

Hello together,
im experiencing some strange error during the setup of a logical standby environment.
primary system running: 10.1.0.3.0 - 64bit Production
log. standby system running: 10.1.0.5.0 - 64bit Production
compatibility flags set to 10.1.0.3.0 on the standby side.
now everything works fine till it comes to the point where I have to register the logical logfile after building the logminer dictionary on the primary site.
Execution flow on the primary site:
SQL> EXECUTE DBMS_LOGSTDBY.BUILD;
SQL> SELECT NAME FROM V$ARCHIVED_LOG WHERE (SEQUENCE#=(SELECT MAX(SEQUENCE#) FROM V$ARCHIVED_LOG WHERE DICTIONARY_BEGIN = 'YES' AND STANDBY_DEST= 'NO'));
gives me:
/oradata/primary/arch/585226884_1_10.arc
Copied to the standby side and tried to register the logfile:
SQL> alter database register logical logfile '/oradata/standby/arch/585226884_1_10.arc';
alter database register logical logfile '/oradata/standby/arch/585226884_1_10.arc'
ERROR at line 1:
ORA-16225: Missing LogMiner session name for Streams
anyone knows what could cause ?
thanks in advance
Chris

It isn't documented anywhere that I know of but yes you can.
Stop SQL Apply, set your Guaranteed Restore Point (GRP) in the Logical standby, run your replay, get the results, flashback the standby to the GRP, open reset logs and restart the apply.
You would need to figure out at what point you would want to run the capture at the primary and stop the SQL Apply at that point or else you will need to flash the logical standby back to the point you started the capture at the Primary and set your Guaranteed Restore point at that point in the database so that Replay can operate correctly (i.e. on the same set of data).
Bear in mind that you during this process you will have two GRP's. One on the standby and one on the Primary. So you need room for the flashback logs at the standby to hold the flashback data and archive logs generated by the replay as well as room for the archive logs coming in from the Primary. And you will need room for the flashback logs at the Primary because it will be still running production during your replay period and generating flashback data there as well.
