Named anchors in scrolling areas

Has anyone successfully placed named anchors inside scrolling
text areas? It works great in Safari but Internet Explorer will
jump to whatever line the anchor is placed on and disregard the
scroll attribute placed in the <div> tag.
I really want this to work in Explorer but I'm stumped. Any
help would be appreciated!
Thanks in advance for any help!

> I really want this to work in Explorer...
Should work fine with IE.

anchor links on the page and inside the div
It's Safari that should have the problem.

Named Anchors don't work in IE 8

Hi everyone,
In my .dwt template file I placed a Named Anchor at the top of the page (not an editable region) and named it "top". At the bottom of the page a link named (top).
All other browsers give a satisfactory result: click on (top) and to the top of the page you go!
IE nope!
http://artdesignsneed.com/joeldoctor/index.html
What can I do?
Thanks for the help!

It seems that IE8 doesn't like named anchor tags that are empty.
1) Try a non-breaking space (or any text content) inside the <a> tag
<a name="top" id="top">& n b s p ; </a>
without any spaces between & n b s p ;
2) or try the inline-block trick mentioned here
http://chrisjean.com/2010/10/20/links-to-named-anchors-or-element-ids-fail-in-ie8/
<a name="top" id="top" style="display:inline-block"></a>
3) or, for a sitewide solution, try using an attribute selector in an IE8-only CC in one of the linked CSS stylesheets
/* ensure named anchors work in IE8 */

What's the trick to positioning named anchors on a side scrolling site?

I'm putting together a page that scrolls to the right. My problem is getting the named anchor for a div that's to the right of the screen to slide over to the left of the screen. Right now it only goes to the right, so what's in the div is still out of view.
Sorry I don't have a link up to what I've started so you can see what I mean.
I've been trying to figure out the CSS and HTML behind www.deanoakly.com to figure out how he does it. Can anyone here take a look to see? Any help is much appreciated!
When I say the page scrolls to the right I mean to the left. It stops at the anchor to the right, but the content I want in view is still to the right. Is there a way of getting that anchor to stop on the left of the screen, rather than the right?

You misspelled the name of the site. It's http://deanoakley.com.
Anyway, it's done using JavaScript. The details of the technique used on that site are here: http://lab.centralscrutinizer.it/the-tiny-scrollings/.

Help!! Why are of my sitemap links not landing on their named anchors?

I've just manually completed a sitemap for my dreamweaver 8 website: http://www.ggordontowerofbabel.co.cc The first 2 pages are fine, with all the links landing just at the spot I want them to.
However, on the 3rd page, they land on the spot, but as soon as the page is fully loaded, it jumps off indiscriminately to another part of the page? This is only a problem once it is loaded onto the server for anyone to access. However, all is fine locally, where only, "MyMediaPage.htm#MyFilm" is applied to the link, but once on the server, I add the full url http://www.ggordontowerofbabel.co.cc//MyMediaPage.htm#MyFilm
Again, all is fine on the first 2 pages on the server, and I'm using the same method.
After removing code from the body tag, it helped only partially. However, now the link lands on the next named anchor instead, almost as catch-up. So, while it may briefly land on its target, it still shoots onto the previous or next one. Please help!!

Hi
Thank you for your help. Since you didn't experience the same problem, I checked the page in IE. It was fine. So, it seems that it is only a Mozilla Freezefox problem, and will need to figure out how to fix that.
I'm gratefull too for your additional information, as all constructive criticism is very welcome, so I will now change the red font colour as you suggested. If you thought it was bad then, I had just changed the font itself from TN Roman to Ariel, so think yourself lucky your eyes were spared that
I've also considered your excellent advice on running the page throught the validator. I've done that. However, reading and understanding html coding is torture for me, as simple, plain English would help me better.
Truly grateful.

Handeling named anchors

Hi
I'm trying to set up an news page on my site. I have one main frame where I want the news articles to be displayed, "News". Linked to the frame New is a html page where I write the articles month by month.
In another frame "search" I have a list of months. in the htlm page linked to "search" I have made each month a link to a named anchor in the "news" page.
My site is set up with css and I have a container 790x650 px. The frames are inside this container. The background is a color defined in css.
I have two problems:
When I search in the "search" frame the entire site scroll upwards. I want the container to stay fixed against the top of my browser and the scrolling to be contained to the frame "news". I have the container centered with a 60 px top margin. Is there a function that will keep the page from scrolling? Should I set it up another way?
I can't get the months I use as links in my "search" doc to list with a normal spacing. How do I change this?
Grateful for all input,
Erik

Hi Nancy

Dreamweaver CS5.5 - Header, Named Anchor and Hidden text

Hello,
I am a relative novice when using dreamweaver. I don't use it in an official capacity, rather than as a Hobby.
I have created a webpage with a position fixed header, displaying a Jump Menu/Drop Down Menu linking to named anchors on the page. I have a css linked to the page using:
#header {
    text-align: center;
    width: 100%;
    background-color: #CFC;
    position:fixed;
    top:0;
    left:0;
    z-index:1000;
When I use the menu to jump to the named anchor (#a04x01), the page will display the text, but the "Chapter One" text is hidden behind the header.
My question is how to either offset the named anchor so when it is jumped to, it appears 200px above where it is meant to (So displaying "Chapter One")?, or to alter the header so it is in a solid state so the text cannot scroll "beneath" it, rather the page considers the bottom on the header the top of the page?.
Any suggestion or solves would be gratefully accepted.
PS: If needed, I can supply the .html page, & .css
Thank you
Regards
TjStorm

Remove position:fixed from your <header> and you won't have that problem. Fixed positioned elements are not part of the normal document flow as they are at fixed coordinates at all times.
This example uses fixed elements with ample top- and bottom-padding between sections. View source to see the code.

Named anchor problem in Firefox

I have some links that go to named anchors. The links are in a library item that is placed in a page template.
The html links look like this: ../mypage_topic.html#anchor, ../mypage_topic2.html#anchor, ../mypage_topic3.html#anchor
The anchor takes you to a section in the page so the viewer doesn't always see the masthead then has to scroll down.
If have just noticed that the anchors don't work in Firefox on a Mac, a solution has been suggested to remove the # from the anchor link.
I don't know if that will work being that I would end up with a html link looking like this: ../mypage_topic.htmlanchor
I'm looking for a fix/workaround to this problem.
Christo

http://www.midcoast.com.au/~christo2/byf_site/teachers_amanda.html
The links are from the teacher names in the right hand column. The named anchor sits between the masthead image and the navigation menu.

Combine pt://return with named anchor tag

I have a situation where I need to use the pt://return transformer tag in order to return to portal. However, I would also like to scroll/focus the page to a named anchor tag.
In other words I have this html on the page that the user is returning to:
<a name="TopNews" id="TopNews"></a>
I need to create a return tag something like this:
Back to Top News
Any suggestion on how to go about doing this is greatly appreciated - Tanner

What are you returning to? A My page, or community page, or other? I'm including some tricks I have used in the past to get the browser to go to a URL on the portal server... they might be worth a try.
If it is a community page you may be able to use a transformer tag and javascript to send the user to the location.
<pt:openerLink xmlns:pt="http://www.plumtree.com/xmlschemas/ptui/" pt:mode="2" pt:classID="512" pt:objectID="OBJECT_ID_HERE" id="NewsCommunityLink"></pt:openerLink>
<script>
function goToNewsCommunity() { <pt:transformer pt:fixurl="off" xmlns:pt='http://www.plumtree.com/xmlschemas/ptui/'/> document.location = document.getElementById('NewsCommunityLink').href + "#TopNews"; <pt:transformer pt:fixurl="on" xmlns:pt='http://www.plumtree.com/xmlschemas/ptui/'/>}
</script>
If it is the users home you might try this:
<script>
function goHome() { <pt:transformer pt:fixurl="off" xmlns:pt='http://www.plumtree.com/xmlschemas/ptui/'/> document.location = "/portal/server.pt?#TopNews"; <pt:transformer pt:fixurl="on" xmlns:pt='http://www.plumtree.com/xmlschemas/ptui/'/>}
</script>

Target Named Anchor in a Spry Collapsible Panel from a different page

Let me start by saying I have combed this forum (and others) looking for a resolution to this. I am familiar with David Powers solution on Foundationphp.com and am using that code in project to open the collapsible panel from a separate page and it works beautifullly. The problem I have is that I want the browser to move down to a specific named anchor inside that opened collapsible panel when clicked from a different page.
Snippets of my current code here.
Below is the code that I have on an image that when clicked goes to the correct page and opens Panel1. Works Perfectly!
<a href="bamboo-species.php?col1=open#CollapsiblePanel1"><img src="images/Content/Photos/HomeScroll/blackTmbor.jpg" width="227" height="175" /></a>
Below is the link to the .js file and the script in the head of the target page
<script type="text/javascript" src="SpryAssets/SpryURLUtils.js"></script>
<script type="text/javascript">
// Grabs the values of the URL parameters for the current URL.
var params = Spry.Utils.getLocationParamsAsObject();
</script>
Below is the code that I have on the target page for Panel1
<script type="text/javascript">
var CollapsiblePanel1 = new Spry.Widget.CollapsiblePanel("CollapsiblePanel1", {contentIsOpen:params.col1 ? true : false},{duration: 1000});
</script>
If I have a named anchor say <a name="species1" id="species1"></a> down in the page, how do I target that named anchor from my link on the separate page. I have tried adding the #species1 to the end of the link on the link page (see below) but with no luck. I believe those were the instructions on foundationphp.com site.
<a href="bamboo-species.php?col1=open#CollapsiblePanel1#species1"><img src="images/Content/Photos/HomeScroll/blackTmbor.jpg" width="227" height="175" /></a>
I hope (and suspect) that this is an easy fix, I just do not know what it is. Any help or direction where to look is greatly appreciated.

I once had the same issue can created a small function that allows me to "jump" to a element.
function scrollTo( element ){
     var stylize = function( element){ return !+"\v1" ? element.currentStyle : document.defaultView.getComputedStyle( element , null ) },
          getPosition = function( element ){
               // based on the SpryEffect's module:
               var computedStyle, tryComputedStyle,
                    position = { x: 0, y: 0 };
                    if ( element.style.left && /px/i.test(element.style.left) ){
                         position.x = parseInt(element.style.left, 10); // without padding
                    } else {
                         computedStyle = stylize( element );
                         var tryComputedStyle = computedStyle && computedStyle.left && /px/i.test( computedStyle.left );
                         if (tryComputedStyle)
                              position.x = parseInt( computedStyle.left, 10 ); // without padding, includes css
                         if(!tryComputedStyle || position.x == 0) // otherwise we might run into problems on safari and opera (mac only)
                              position.x = element.offsetLeft;   // includes padding
                    if ( element.style.top && /px/i.test(element.style.top) )
                         position.y = parseInt( element.style.top, 10); // without padding
                    else
                         if ( !computedStyle )
                              computedStyle = stylize( element );
                    var tryComputedStyle = computedStyle && computedStyle.top && /px/i.test( computedStyle.top );
                         if ( tryComputedStyle )
                              position.y = parseInt( computedStyle.top, 10 ); // without padding, includes css
                         if( !tryComputedStyle || position.y == 0 ) // otherwise we might run into problems on safari and opera (mac only)
                              position.y = element.offsetTop;   // includes padding
               return position;
          scroll( 0, getPosition( element ).y );
So now we have a scrollTo function that accepts a pure HTML element as argument, all what is left to do is figure out if we have a hash, and if the anchor exits on the page.
( hopes this works, i wrote it without testing, but you get the general idea ):
if( window.location.hash ){
     var hash = window.location.hash.substr(1), // remove the # from the hash
     element;
     // as anchors can also be used with id attributes, check that first,
     element = document.getElementById( hash );
     // maby we used name="" attribute
     if( !element && ( element = document.getElementsByName( hash )) ){
          element = element[0];
     // if we have a match:
     if( element ){
          // give the collapsible panel some time to init and update the DOM;
          setTimeout(function(){ scrollTo( element ) },0);

Links to id's and named anchors within a page in an iframe do not open in firefox

In order to force layout of my liquid website, I use i-frames to display content . It is all on my sight www.rdelutherie.com, and I am not displaying pages from other sights. The links to sections of pages from within the same page do not work in firefox.
I have had this problem before with named anchors, and in moving up to html5 and in making my site accessible for people with dissabilities, I started using <nav> eliments... and changed from named anchors to links to ID's like this:
In an unordered list I have these:
<pre><nowiki> <li><a href="#s1">Subject 1:</a></li>
</nowiki></pre>
They link to sections of the same page like this one:
<pre><nowiki>
<section id=s1>
<h2>Subject 1:</h2>
<p>Blah blah blaaaaah, and bla bla!</p>
</section></nowiki></pre>
Last time I researched this problem (a year or more ago), I was told that it was because of a security risk (something about being able to count views...and other peoples proprietary and copyrighted material), but the vaguely described reasoning made little to no sense to me nor many others, who can not even link to our own stuff. The Mozilla developers were rather abrupt and some were even rude in telling us to live with it, instead of trying to come up with a solution or work around, and closed the post and disallowed further posting.
The problem still persists, and although I am not a programmer, I have a real hard time believing that it is impossible for Firefox to distinguish between links contained within a document and site, from those on different sights, domains and what have you.
As far as I know, no other browsers have this problem, so if it is such a big security risk, what is to stop someone with malicious intentions, from just using M$ IE, to bring their evil plan to fruition?
In keeping with "Making the web a better place": Please address this problem, and find a solution, workaround, or at least explain why it is impossible.
Bob English

Thanks again jscher2000,
I know exactly what you mean, but I have had other page display problems with adjacent columns where one side does not display completely and seems to be conforming to the other ones height... hence the height settings and other tricks to force things to be acceptable.
I am far from understanding code, and most of the solutions, including the one in the link you posted do not have the information a novice like me would need to implement them successfully. Most of them are written for people much more advanced. Without it telling me where exactly to put the code, point to it, what I can (and should) change and remove elsewhere because of it... I am at a loss. I don't know the basics, and have tried hard to understand them, but it is not like electrical circuits, physics and other things that I can understand naturally and with ease.
I will look into it further in a few days, meanwhile I have to attend to my real work that doesn't even pay the bills completely: guitar building and repair, now that comes easy and naturally to me!

RE: Named anchored objects

Albert,
In my case I was using a named anchored object to get a handle to an actual
service object. My named object that I registered in the name service was
an intermediary to which I did not maintain a connection. So I have not
explicitly tested what you are asking.
However, I too was not using a hard coded reference to the SO, and fail over
and load balancing worked fine. The functions of fail over and load
balancing are not done by the service object but by the name service, proxy
and router. Since you are getting a proxy back any time you do a lookup in
the name service I would think that fail over should work with any anchored
object that is registered in the name service. When you do a RegisterObject
call you will notice that one of the arguments is the session duration,
which implies to me that fail over will be handled the same as for service
objects.
Load balancing adds another wrinkle. Load balancing is handled by a router.
You must get a proxy to the router and not a proxy to an instance of the
object that the router is doing the load balancing for. In the latter
scenario you will be bypassing the router. If you are creating, anchoring
and registering your objects dynamically you will not have a router so you
will not be able to load balance! This applies even if the objects are
instantiated within partitions that are load balanced because you will still
be getting proxies back to a particular instance of the anchored objects.
There are ways to accomplish load balancing between objects that you
register yourself. However, the best solution will vary depending on the
actual problem trying to be solved. If you would like to discuss this
further, include a little more detail about the scenario you need to
implement and I will give you what I know.
BTY what I have outlined above also applies to getting references via a
system agent.

My question about both solutions (using Nameservice and agents) is:
If I reach a remote service object using either a BindObject or an agent, do
fail-over and load-balancing work the same way as they normally do when
using a hard coded reference to the SO.

Alexander,
I can not comment on the speed difference because I never tested it.
But, I
will say that we looked at the agent solution at a client sight
before. I
will give the same warning I gave them. If you go the agent direction
you
are now using agents for a purpose that they were not intended. Even
though
it technically works, as soon as you start using a piece of
functionality in
a way the developer did not intend it to be used you run the risk of
forward
compatibility problems. By this I mean, since agents were not
originally
intended to be used to look up service / anchored object references,
it may
not work in the future because it is not likely to be given
consideration in
any future design.
As we all know, programmers are always stretching the bounds of the
tools
they use and you may have a good reason (i.e. performance). I just
wanted to
let you know the possible risk.
One final note on a limitation of using system agents to obtain
references
to anchored objects. You can not access agents across environments.
So, if
you have connected environments and need to get references to services
in
another environment for fail-over or whatever, you will not be able to
do it
with agents.
Just some thoughts!

David,
The problem with dynamic binding is that in this case you have to keep
the reference to the service object somewhere. You don't want to call
"bindObject" every time you need to use this service object, "bind" is
a
time-consuming operation, even on the same partition. Keeping
reference
could be undesirable if your object could be moved across partitions
(e.g. business object).
The alternative solution is to use agents. You can create custom
agent,
make it a subagent of an active partition agent and use it as a
placeholder for whatever service you need. "FindSubAgent" works much
faster than "bindObject", we verified that and agent is "user-visible"
by its nature.

I actually determined it through testing. In my case I did not want

happen and was trying to determine why it was happing. It makes sense
if
you think about it. Forte is trying to avoid making a remote method
invocation if it can.
Now, for anything more complex than looking locally first and if none

more

Subject: RE: multiple named objects with the same name and interface
David,
there's a mechanism used within SCAFFOLDS that allows the
location of the 'nearest' SO when more than one is available.
It involves registering each duplicated SO under three dynamically
built
names. The names include the partition, the node or the environment
name.
When wishing to locate the nearest SO the BO builds a SO name using
its
own partition and asks the name service for that.
If there is an SO registered under that name then it must be in the
same
partition and all is well. No cross partition calls.
If not, then the BO builds the name using its node and asks the name
service for that.
This means that if there is an SO outside the BO partition but still
on
the same node then this can be used. Again, relatively 'local'.
If neither of these work then the BO has to resort to an environment
wide search.
It may be that this approach could be adapted / adopted; I like it's
ingenuity.

Sean,
First, thank you for your response. I have wondered about this fora
long time.
I looked at the documentation for ObjectLocationManager and on page
327
of the Framework Library and AppletSupport Library Guide indescribing
the BindObject method Forte says:
"The name service allows more than one anchored object (from
different
partitions) to be registered in the name service under the same
registration name. When you invoke the BindObject method with a
request
for a name that has duplicate registration entries, the BindObject
method finds an entry corresponding to an active partition, skipping
any
entries that do not. If no such active partition is found, or if the
requested name is not found in the name service registry, a
RemoteAccessException will be raised when the BindObject method is
invoked."
My question is: How did you discover that in the case of duplicate
registrations the naming service will return the local object if one
exists? This is not apparent from the documentation I have quoted.
Is
it documented elsewhere? Or did you determine it empirically?

David,
First I will start by saying that this can be done by using named
anchored
objects and registering them yourself in the name service. There is
documentation on how to do this. And by default you will get mostof
the
behavior you desire. When you do a lookup in the name service
(BindObject
method) it will first look in the local partition and see if thereis
a

Subject: multiple named objects with the same name and interface
All,
More than once, I have wished that Forte allowed you to place named
objects with the same name in more than one partition. There aretwo
situations in which this seems desirable:
1) Objects that are not distributed, but are mobile (passed by value
to
remote objects), cannot safely reference a Service Object unless it
has
environment visibility, but this forces the overhead of a remote
method
call when it might not otherwise be necessary. If it were possibleto
place a copy of the same Service Object (with user visibility) ineach
partition, the overhead of a remote method call could be avoided.
This
would only be useful for a service object whose state could besafely
replicated.
2) My second scenario also involves mobile objects referencing a
Service
Object, but this time I would like the behavior of the calledService
Object to differ with the partition from which it is called.
This could be accomplished by placing Service Objects with the same
name
and the same interface in each partition, but varying the
implementation
with the partition.
Does anyone have any thoughts about why this would be a good thingor
a
bad thing?

Albert,
In my case I was using a named anchored object to get a handle to an actual
service object. My named object that I registered in the name service was
an intermediary to which I did not maintain a connection. So I have not
explicitly tested what you are asking.
However, I too was not using a hard coded reference to the SO, and fail over
and load balancing worked fine. The functions of fail over and load
balancing are not done by the service object but by the name service, proxy
and router. Since you are getting a proxy back any time you do a lookup in
the name service I would think that fail over should work with any anchored
object that is registered in the name service. When you do a RegisterObject
call you will notice that one of the arguments is the session duration,
which implies to me that fail over will be handled the same as for service
objects.
Load balancing adds another wrinkle. Load balancing is handled by a router.
You must get a proxy to the router and not a proxy to an instance of the
object that the router is doing the load balancing for. In the latter
scenario you will be bypassing the router. If you are creating, anchoring
and registering your objects dynamically you will not have a router so you
will not be able to load balance! This applies even if the objects are
instantiated within partitions that are load balanced because you will still
be getting proxies back to a particular instance of the anchored objects.
There are ways to accomplish load balancing between objects that you
register yourself. However, the best solution will vary depending on the
actual problem trying to be solved. If you would like to discuss this
further, include a little more detail about the scenario you need to
implement and I will give you what I know.
BTY what I have outlined above also applies to getting references via a
system agent.

My question about both solutions (using Nameservice and agents) is:
If I reach a remote service object using either a BindObject or an agent, do
fail-over and load-balancing work the same way as they normally do when
using a hard coded reference to the SO.

Alexander,
I can not comment on the speed difference because I never tested it.
But, I
will say that we looked at the agent solution at a client sight
before. I
will give the same warning I gave them. If you go the agent direction
you
are now using agents for a purpose that they were not intended. Even
though
it technically works, as soon as you start using a piece of
functionality in
a way the developer did not intend it to be used you run the risk of
forward
compatibility problems. By this I mean, since agents were not
originally
intended to be used to look up service / anchored object references,
it may
not work in the future because it is not likely to be given
consideration in
any future design.
As we all know, programmers are always stretching the bounds of the
tools
they use and you may have a good reason (i.e. performance). I just
wanted to
let you know the possible risk.
One final note on a limitation of using system agents to obtain
references
to anchored objects. You can not access agents across environments.
So, if
you have connected environments and need to get references to services
in
another environment for fail-over or whatever, you will not be able to
do it
with agents.
Just some thoughts!

Subject: RE: multiple named objects with the same name and interface
David,
The problem with dynamic binding is that in this case you have to keep
the reference to the service object somewhere. You don't want to call
"bindObject" every time you need to use this service object, "bind" is
a
time-consuming operation, even on the same partition. Keeping
reference
could be undesirable if your object could be moved across partitions
(e.g. business object).
The alternative solution is to use agents. You can create custom
agent,
make it a subagent of an active partition agent and use it as a
placeholder for whatever service you need. "FindSubAgent" works much
faster than "bindObject", we verified that and agent is "user-visible"
by its nature.

David,
I actually determined it through testing. In my case I did not want
this to
happen and was trying to determine why it was happing. It makes sense
if
you think about it. Forte is trying to avoid making a remote method
invocation if it can.
Now, for anything more complex than looking locally first and if none
is
found give me any remote instance you can find, you will need to do
more
work. Using a naming scheme like Jez suggests below works well.

Subject: RE: multiple named objects with the same name and interface
David,
there's a mechanism used within SCAFFOLDS that allows the
location of the 'nearest' SO when more than one is available.
It involves registering each duplicated SO under three dynamically
built
names. The names include the partition, the node or the environment
name.
When wishing to locate the nearest SO the BO builds a SO name using
its
own partition and asks the name service for that.
If there is an SO registered under that name then it must be in the
same
partition and all is well. No cross partition calls.
If not, then the BO builds the name using its node and asks the name
service for that.
This means that if there is an SO outside the BO partition but still
on
the same node then this can be used. Again, relatively 'local'.
If neither of these work then the BO has to resort to an environment
wide search.
It may be that this approach could be adapted / adopted; I like it's
ingenuity.
Cheers,
Jez

Subject: RE: multiple named objects with the same name and

Sean,
First, thank you for your response. I have wondered about this fora
long time.
I looked at the documentation for ObjectLocationManager and on page
327
of the Framework Library and AppletSupport Library Guide indescribing
the BindObject method Forte says:
"The name service allows more than one anchored object (from
different
partitions) to be registered in the name service under the same
registration name. When you invoke the BindObject method with a
request
for a name that has duplicate registration entries, the BindObject
method finds an entry corresponding to an active partition, skipping
any
entries that do not. If no such active partition is found, or if the
requested name is not found in the name service registry, a
RemoteAccessException will be raised when the BindObject method is
invoked."
My question is: How did you discover that in the case of duplicate
registrations the naming service will return the local object if one
exists? This is not apparent from the documentation I have quoted.
Is
it documented elsewhere? Or did you determine it empirically?

David,
First I will start by saying that this can be done by using named
anchored
objects and registering them yourself in the name service. There is
documentation on how to do this. And by default you will get mostof
the
behavior you desire. When you do a lookup in the name service
(BindObject
method) it will first look in the local partition and see if thereis
a
local copy and give you that copy. By anchoring the object and
manually
registering it in the name service you are programmatically creating
your
own SO without defining it as such in the development environment.
BTW
in

your "mobile" object is in the same partition where the serviceobject

It end ups as more or less a random selection. Off the top of myhead

Named Anchored Obj-Environment Failover

Hi to all,
We connect from EnvA to EnvB giving the user directory parameter as / and
set the Environment Search Path
as EnvA:EnvB. From both environments we start and register
'/glob/obj1' named anchored objects with the same name.
From a client we connect to EnvA and bind to'/glob/obj1' when we shutdown EnvA partition it fails-over to
EnvB. And then we restart EnvA partition. We restart/rebind the client and
try to use object. We see that it is using the EnvB object.
Although we started the primary environment object again.
It is not using the search path. Once we shutdown secondary environment
it starts using primary environment object.
When we try to use relative path when we are binding the object
First parameter ('glob/obj1') No first slash. Trying 3rd parameter
for bind function or just using environment search path, Is is not able to
find the object. From nsls command I figured out that
under the root directory
/forte/UUID of ENVA/node
/site
/UUID of ENVB
/glob/obj1
names are available. When we use relative path (without slash)
is it trying to find /glob/obj1 under the /forte/UUID of ENVA
but we are registering the name under the root.
What is the reason of this odd behaviour or is this a bug?
Any answer will be appreciated,

Hi Juliesmiley,
According to your description, I recommend you check the conditions required for an automatic failover.
• Primary replica and secondary replica are both configured for syschronous-commit mode and set to AUTOMATIC failover.
• All availability databases that are defined in the availability group must be in a SYNCHRONIZED state between the primary replica and the secondary replica.
• The Windows Server Failover Clustering (WSFC) cluster has quorum.
• The primary replica has become unavailable.
For more information, please review the following articles.
Failover and Failover Modes (AlwaysOn Availability Groups)
Troubleshooting automatic failover problems in SQL Server 2012 AlwaysOn environments
Thanks,
Lydia Zhang

RE: (forte-users) Named Anchored Obj-EnvironmentFailover

I did some playing around with this stuff as well. I can tell you a few
things.
1) The search path option of connected environments only works for SO's, not
for named anchors.
2) When EnvA creates a directory "/glob", which contains object "obj1", then
EnvA owns directory "/glob". Even after restarting environments. If EnvB
tries to add a subdirectory to "/glob" or inserts its own objects into this
path, then the situation becomes unstable. It doesn't immediately produce an
error, but things go wrong anyway. Is this a bug or expected behaviour? I
don't know. I just learned not to do this. Every environment must place it's
named anchors in it's own tree. Directories can't be shared.
3) I think the relative name "glob/obj1" should work, but only if you set
the ObjectLocationMgr to start looking at the root. Default, it will start
looking in it's own environment basepath. But I don't have any experience
with this.
