Javascript alert when showing all rows of a huge table ( 2000 rows)

Question

i've got this problem. I need to show all the rows of a table, i'm using ADF 10.1.3.4.
What have i done so far?first of all i created a command link
<af:commandLink shortDesc="Mostra Tutto" id="showAll"
disabled="#{bindings.findAllVwEntePrmzRefrIter.estimatedRowCount == 0}"
action="#{backing_editReferenza.onShowAll}"
/>
In the backing bean i set the rangeSize of the table to -1
public String onShowAll() {
Object objShowAll = getSession().getAttribute("showAll");
FacesContext fc = FacesContext.getCurrentInstance();
ValueBinding vb = fc.getApplication().createValueBinding("#{bindings.findAllVwEntePrmzRefrIter}");
DCIteratorBinding dc = (DCIteratorBinding)vb.getValue(fc);
int oldRangeSize = dc.getRangeSize();
dc.setRangeSize(-1);
int rangeSize = dc.getAllRowsInRange().length;
dc.setRangeSize(oldRangeSize);
if ("Y".equals(objShowAll)) {
getSession().removeAttribute("showAll");
Integer oldRange =
(Integer)getSession().getAttribute("oldRangeSize");
getSession().removeAttribute("oldRangeSize");
getTable1().setRows(oldRange);
} else {
getSession().setAttribute("showAll", "Y");
getSession().setAttribute("oldRangeSize", oldRangeSize);
getTable1().setRows(rangeSize);
return "";
// AdfFacesContext.getCurrentInstance().addPartialTarget(getTable1());
Everything runs smoothly, but i have a problem if the table has lots of rows: i get a javascript warning that a script has been running for too long. (The alert goes: "Stop the execution of the script?" the usual javascript alert you get when a script runs for too long)
What i want to achievt is that, if the table contains a lot of rows, the page takes a lot of time to load, but with no javascript involved (it's just a normal slow page).
It seems that in some way the rows of the table are fetched by javascript and since the call is synchronous, it trigger the alert.
This is how i declared the method iterator
<methodIterator id="findAllVwEntePrmzRefrIter"
Binds="findAllVwEntePrmzRefr.result"
DataControl="FePrmzSLESSEJBLocal" RangeSize="10"
BeanClass="it.ws.sma.prmz.ejb.model.VwEntePrmzRefr"
Refresh="deferred"
/>
and this is how i declared the table
<af:table value="#{bindings.findAllVwEntePrmzRefr1.collectionModel}"
var="row" styleClass="tableRefr #{backing_editReferenza.tableReferenzeStyleClass}"
rows="#{bindings.findAllVwEntePrmzRefr1.rangeSize}"
first="#{bindings.findAllVwEntePrmzRefr1.rangeStart}"
emptyText="#{bindings.findAllVwEntePrmzRefr1.viewable ? 'Nessuna referenza trovata' : 'Accesso negato'}"
binding="#{backing_editReferenza.table1}" id="table1"
banding="row" bandingInterval="1"
partialTriggers="btnEliminaRefr btnSvuotaPromo btnRemove btnAdd insVeloce">
has anyone an idea onwhat could i do to have the table load all the rows from the server but withouth the alert?

Sorry i haven't explain it well...
the app is used to replicate entire databases, or agrupations of tables, from one database to another and it will have to be vendor independent... I'm trying with DB2, Oracle and MySQL. Later i will test it with more.
Then I couldn't use vendor dependent SQL neither configuration parameters. Also I prefer to make the import logging the actions: for restoring purposes; maybe the user will have the option but defaults to the ohter.
I'm thinking about some "strange" query SQL Stardard, like delete from table where (select .... using some kind of counter....
