Solution Details:
1. Do an ETROLLOVER on Extract, and take note of the new sequence number of the trail file.
ALTER EXTRACT ESCDB002, ETROLLOVER

2. Start extract
START EXTRACT ESCDB002

3. Send PUMP, LOGEND, to see if it's at the end of the previous trail.
SEND EXTRACT PNFHC002, LOGEND

4. Once it is at the end of the trail file, You must stop the pump, and do an ETROLLOVER for it too. Take note of the new trail file sequence number that is created from this step.
STOP EXTRACT PNFHC002
ALTER EXTRACT PNFHC002, ETROLLOVER

2013-03-20 14:17:30  INFO    OGG-01520  Rollover performed.  For each affected output trail of Version 10 or higher format, after starting the source extract, issue ALTER EXTSEQNO for that trail's reader (either pump EXTRACT or REPLICAT) to move the reader's scan to the new trail file;  it will not happen automatically.
EXTRACT altered.

5. Alter the pump to SEQNO to the new trail file created from step #1.
ALTER EXTRACT PNFHC002, EXTSEQNO 21 EXTRBA 0

6. Restart pump
START EXTRACT PNFHC002

7. Send Replicat, LOGEND to make sure it has processed all the remaining data, and stop Replicat.
SEND REPLICAT RSCDB002, LOGEND
STOP REPLICAT RSCDB002

8. If replicat is not at end of trail, generate a report and forcestop replicat
SEND REPLICAT RSCDB002, REPORT
STOP REPLICAT RSCDB002

9. Add the following parameters to replicat parameter file to allow replicat to process each trail record as a single transaction, or set them to 1 if you have any of these parameters:
GROUPTRANSOPS 1
MAXTRANSOPS 1

10. Restart replicat
START REPLICAT RSCDB002

11. Once replicat has completely processed the trail, stop the replicat
STOP REPLICAT RSCDB002

12. Edit the replicat parameter file:
     - Add parameter HANDLECOLLISIONS to Replicat parameter file
     - Remove or comment out GROUPTRANSOPS and MAXTRANSOPS or revert them back to their original values.

Note: There are pre-conditions for using  HANDLECOLLISIONS . Ther emust be either

a. no pkupdates
or
b. extract  has "FETCHOPTIONS FETCHPKUPDATECOLS"Also all the tables should have Primary key or unique index on the table to avoid data integrity issues when using handlecollisions.

13. ALTER REPLICAT, SEQNO to the new trail file created in step #4.
ALTER REPLICAT RSCDB002, EXTSEQNO 5 EXTRBA 0

14. Start Replicat
START REPLICAT RSCDB002

15. Once Replicat has processed the out of order SCN operations, disable HANDLECOLLISIONS. You could also look for the CSN and wait for Replicat to checkpoint past it.
SEND REPLICAT RSCDB002, NOHANDLECOLLISIONS.

16.Edit the replicat parameter and comment out the HANDLECOLLISIONS parameter. You do not need to stop/restart replicat. This will ensure that on any subsequent replicat restarts the parameter is disabled.

根据oracle给出的文档，测试参数如下：
THREADOPTIONS MAXCOMMITPROPAGATIONDELAY 60000 IOLATENCY 90000
