Instead of PROC_RUN_ID_SEQ I am getting-> DEBUG main SQL logStatement:92 - select hibernate_sequence.nextval from dual

Answer 1

The causes can be different:
The name of the sequence you have mapped in your pojo is different
You have no permission to use sequence
You have no defined a sequence on your database
Solutions
Fix the sequence name on your pojo
Grant the sequence for your database user
Add the sequence on your database
EDIT AFTER UPDATED QUESTION
Try as follow:
<id name="propName" type="long" unsaved-value="null">
<column name="columnName" not-null="true" unique="true"
index="pkName" />
<generator
class="org.hibernate.id.enhanced.SequenceStyleGenerator">
<param name="optimizer">none</param>
<param name="increment_size">1</param>
<param name="sequence_name">PROC_RUN_ID_SEQ</param>
</generator>
</id>
