Force Routing Over second link?

We have a MPLS WAN connecting our offices from our Service Provider. Our Head Office has a larger 50Mbps pipe and a remote office has 2 separate 2Mbps links (lets call them link1 and link2). Right now all traffic only goes over Link1 at the remote office as per all the BGP routing. I can make a static route at the remote office for specific traffic to go over link2 and it will successfully send over that link. My question is, is there a way to get traffic from Head Office to go to Link2 instead of Link1?

It primary depends on BGP routing. You can try to change the way ISP send traffic to you branch using different BGP path attribute in advertisement on the two links but you have to negotiated with ISP because they can also "force" their netwrok to use on path instead of the other for example using BGP local preference. I suggest you to read here to understand BGP algorithm:

Interactive report performance problem over database link - Oracle Gateway

Hello all;
This is regarding a thread Interactive report performance problem over database link that was posted by Samo.
The issue that I am facing is when I use Oracle function like (apex_item.check_box) the query slow down by 45 seconds.
query like this: (due to sensitivity issue, I can not disclose real table name)
SELECT apex_item.checkbox(1,b.col3)
, a.col1
, a.col2
FROM table_one a
, table_two b
WHERE a.col3 = 12345
AND a.col4 = 100
AND b.col5 = a.col5
table_one and table_two are remote tables (non-oracle) which are connected using Oracle Gateway.
Now if I run above queries without apex_item.checkbox function the query return or response is less than a second but if I have apex_item.checkbox then the query run more than 30 seconds. I have resolved the issues by creating a collection but it’s not a good practice.
I would like to get ideas from people how to resolve or speed-up the query?
Any idea how to use sub-factoring for the above scenario? Or others method (creating view or materialized view are not an option).
Thank you.
Shaun S.

Hi Shaun
Okay, I have a million questions (could you tell me if both tables are from the same remote source, it looks like they're possibly not?), but let's just try some things first.
By now you should understand the idea of what I termed 'sub-factoring' in a previous post. This is to do with using the WITH blah AS (SELECT... syntax. Now in most circumstances this 'materialises' the results of the inner select statement. This means that we 'get' the results then do something with them afterwards. It's a handy trick when dealing with remote sites as sometimes you want the remote database to do the work. The reason that I ask you to use the MATERIALIZE hint for testing is just to force this, in 99.99% of cases this can be removed later. Using the WITH statement is also handled differently to inline view like SELECT * FROM (SELECT... but the same result can be mimicked with a NO_MERGE hint.
Looking at your case I would be interested to see what the explain plan and results would be for something like the following two statements (sorry - you're going have to check them, it's late!)
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two),
sourceqry AS
(SELECT b.col3 x
       , a.col1 y
       , a.col2 z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5)
SELECT apex_item.checkbox(1,x), y , z
FROM sourceqry
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two)
SELECT apex_item.checkbox(1,x), y , z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5If the remote tables are at the same site, then you should have the same results. If they aren't you should get the same results but different to the original query.
We aren't being told the real cardinality of the inners select here so the explain plan is distorted (this is normal for queries on remote and especially non-oracle sites). This hinders tuning normally but I don't think this is your problem at all. How many distinct values do you normally get of the column aliased 'x' and how many rows are normally returned in total? Also how are you testing response times, in APEX, SQL Developer, Toad SQLplus etc?
Sorry for all the questions but it helps to answer the question, if I can.
Cheers
Ben

FXO traffic is going over Wan link after enabling QoS

Hi,
We have CCM 5.0,2811 voice gateway,1 4FXO and 1 g.shdsl card on it. 4 Telco lines are on 4FXO card.CCM is at the other side of g.shdsl line.Topology like that,
2811 ---------------- CCM
4fxo g.shdsl
When a call receives from FXO port, system is working normally without QoS. When we enable QoS traffic,traffic is going over wan link then return again.Because of that,delays and timeouts occuring.Router's config is at the attachment. Please Help!
Thank you

Check your H323 gateway config in CCM to be sure the Media Termination Point Required box is unchecked. Using MTP forces the call to terminate on the closest MTP resource which is likely at your CCM site.

OSPF prefer learned route over local

Hey
I am deploying a new VPLS between 8 offices. The plan in to have all the offices get internet access through the main office. So basically all the satellite offices will only have access to the VPLS WAN link. The main office will advertize a default route to the rest of satellite offices over OSPF.
Each office currently has its own internet connection. I would like to maintain each office's internet connection until we have completed deployment of the VPLS and have thoroughly tested it.
So my question is this. How to i configure OSPF to prefer the learned default route, over the default route it has statically configured?
thanks for your help
Dan

Dan
Without knowing the full topology it's difficult to say for sure but as a general answer you can't really.
Even if you tried to set the AD of OSPF to be the same as the static route, which I'm not sure would be a good idea, the locally configured static would have a better metric.
I think you are basically going to have to test by advertising out the default route via OSPF, making sure it is in the OSPF database at each site and then remove the locally configured default to test internet connectivity via your main branch.
Or you could try using PBR to bypass the routing table which would allow you to test central internet connectivity but it doesn't confirm your OSPF routing is working properly.

Hi,
We are on Oracle 11.2.0.2 on Solaris 10. I have two databases on this version of Oracle. From one db I have execute a stored procedure via db link to another database. The store procedure has dynamic sqls (execute immediate) and it uses commit statement as part of the code. Is it alllowed to execute this procedure over db link? I am not aware on the implications on stored proc execution over db link and will be thankful for help.
Thanks,if no error is thrown, why are you looking for problems where none exist?

Report over database link error

Good morning all.
I have a database link LINKA from USERA on LOCALSERVER to USERB on REMOTESERVER.
(create database link LINKA connect to USERB identified by mypassword using validtns)
In USERC on REMOTESERVER I have a TABLEX, with grant all on TABLEX to USERB on REMOTESERVER.
In USERB on REMOTESERVER I have a view TABLEXV, select * from USERC.TABLEX
From USERA on LOCALSERVER I can select * from TABLEXV@LINKA. In fact I can insert/update/delete tablexv from USERA.
I also have a view TABLEXV on USERA, select * from TABLEXV@LINKA. I can also select/insert/update/delete from USERA.TABLEXV.
So far so good - all working as expected.
Then, my APEX app on LOCALSERVER, interactive report, parsing schema USERA, querying TABLEXV, I get the following:
when "Exclude Link Column", I get the error "The requested URL /pls/apex/f was not found on server.
when "Link to Single Row View", report displays correctly.
when "Link to Custom Target", I get the error "The requested URL /pls/apex/f was not found on server.
When I run the select * from TABLEXV as a regular report (i.e. not interactive), I also get the error.
So the only time I get the report displayed correctly is using IR and "Link to Single Row View".
However, clicking on the link (for Single Row View) I get "The requested URL /pls/apex/wwv_flow.show was not found on this server.".
To summarize:
- accessing table via view over database link
- works outside of apex without issue
- inside only works when Link to Single Row View set
- But clicking on link fails
I could live with just having the Link to Singe Row View option if I could disable displaying of the icon so that the user cant click on it.
APEX 3.2.00.27
EE Database - 10.2.0.3 (yes I know out of support)
Remote EE Database - 10.2.0.5
Real object names replaced to protect the innocent!
Anyone got any clues?
I have used remote tables many times in my APEX applications and never had this issue.
Thanks,

Mouse-over a link

when i mouse-over a link, i can see where that link brings me in the lower left corner. but when i enable the search (shift+f), the links are in the lower RIGHT corner. why? its really embarassing for example on facebook, because the chat windows can be found at the lower right corner, right where are these "links". can i change it some way? thanks in advance!

You can use this extension to change that behavior:

Mouse over HTML link causes single frame to display at top of page Netscape only

Having a wierd problem. When you run the mouse over HTML
links on the page a single frame of the flash movie apears at the
top center of the page. It only happens in netscape in firefox
mode. IE, Opera, and Firefox do not have the problem.
Problem site
Thanks in Advance,
Vorsch

The problem goes away if i modify my .css file by removing
the
border: 1px solid #999999;
line from the "a:hover" style.
I ran my css file thru the validator at w3c and its fine. The
Page also validates as xhtml transitional.
and just a note the same file version is on my public server
and my testing server.
Has anyone ever seen this before?? I have several sites with
a:hover effects and flass media and have never run across this
before.

In WebHelp, when I mouse over a link, the font size changes.

Either after I generate to WebHelp or View in RoboHelp, when I mouse over a hyperlink text, the font changes from large to small text. My step is a 11pt font, my body text is 10pt. It appears the 11 pt. font switches to 10pt font when I mouse over it. Any way to fix this?
Also noticed that when I have a note at 9 pt, and mouse over a link, the text changes to 10pt.
So now it appears in most of my topics with links within a step or note. In a body, the text appears fine (or stays the same) when you mouse over a link.

Not believing that either.
You should be able to edit your CSS in a text editor. If you are not sure what to do, set up a simple project using your CSS. Any text will do and create a link.

I want to know how to get the web addresses to go away that appear in the bottom left corner of the browser every time my mouse goes over a link

Any time that my mouse goes over a link on a web page a little box in the bottom left corner of the browser pops up showing the web address for that link and it is really annoying, especially when i am on facebook because there are so many links on the home page i cant move my mouse anywhere without that box popping up and blocking part of my conversations. I was wondering if there was any way to turn this off. I've checked through the options and to my knowledge there is no way to turn it off. Just wondered if anyone else has had this problem or knew if there was a way to get that box to go away.

Another option would be to use the following extension to push those messages into the status bar. It could be a convenient way to have your messages visible when you want them, but with less distraction.

How do I turn on and turn off the pop-up that displays the true URL when I hover over the link?

I would like to know how to set Firefox so it displays the true URL of a link when I hover my mouse over that link.

It's been many moons since I've used a Fireberd, since I'm no longer with the phone company, but if memory serves, that can be turned of directly with a fireberd command. You might check the manual for that. If so, then all you need is a simple "send GPIB" command from Labview

My link preview has disappeared from the bottom left of the page (it no longer pops up when I hover over a link.) Thoughts on how to get it back? I really LIKE having it!

My link preview has disappeared from the bottom left of the page (it no longer pops up when I hover over a link.) Thoughts on how to get it back? I really LIKE having it!

It is possible that the screen is too high and that the scroll bar and the find bar and add-on bar fall off at the bottom.
If that works then close Firefox (File > Exit/Quit) to save that setting.
