typically you would
change the jrn to the next receiver
back-up the receiver
delete the receiver
<i>…how to clear the above list without deleting receiver?</i>
For that question, the answer is “You can’t.”
That is, high-level programming can not access journal entries to clear or delete them. That’s why journals can be far superior to files for audit logs.
But note that this doesn’t appear to be the correct question. Your later comment was “Actually I tried using RMVJRNCHG, but its now worked for me.” Perhaps you meant to say “…its <b>not</b> worked for me.”
Please clarify what you need to know.
Removing journaled changes <i>is not</i> the same as clearing entries from a receiver.
