Answer 1

Particularly this passage:
MaxBlockTime
MaxBlockTime is the time in mili seconds to wait when reading data from the
Runform process.
e.g. a long query, lots of complex processing
(default = 1000 milli sec)
/j2EE/OC4J_BI_Forms/application/forms90app/forms90web/WEB-INF/web.xml
or
/j2EE/OC4J_BI_Forms/application/formsapp/formsweb/WEB-INF/web.xml
Example
=======
<servlet>
<servlet-name>l90servlet</servlet-name>
<servlet-class>oracle.forms.servlet.ListenerServlet</servlet-class>
<init-param>
<param-name>maxBlockTime</param-name>
<param-value>1800000</param-value>
</init-param>
</servlet>
or
<servlet>
<servlet-name>lservlet</servlet-name>
<servlet-class>oracle.forms.servlet.ListenerServlet</servlet-class>
<init-param>
<param-name>maxBlockTime</param-name>
<param-value>1800000</param-value>
</init-param>
</servlet>
What happens?
=============
For long requests (like querying a big table), the Listener
Servlet waits for a default time of 1 second for the Forms
runtime process to complete the request
If the request is not completed then the Listener Servlet sends a busy
response to the client asking the client to retry.
The client sends a retry zero content length request to check if the query is
complete.
This default time of 1 second can be configured using Listener Servlet
parameter called maxBlockTime
