Urgent: MAC fails issue

Hi ,
I would like to ask this question again to oaf top users/gurus( Tapash Ray ,Shiv Saroj,Mukul Gupta,Ramkumar Sekar,Sumit Sharma, avajain, Srinath Mani) to put some light on this issue. Many thanks!
 
Hi OAF Guru's
 
My goal is to communicate between projects screen and ESRI MAP.
If I want to click on a button in the projects screen then I want to zoom in to a group of geometry regions in the ESRI MAP.
If I want to click in the ESRI MAP in a region then I want to do something in projects screen such as navigating to another projects screen etc.
 
To realize this goal: 
I have extended a standard Projects page and add a region to show a ESRI GIS map.
 
To be exact:
 
ProjectSetDetailsPG
PA_PROJECT_SET_DETAILS_LAYOUT: (Region Style: PageLayout) 
...... 
<my additions> 
GisMapHdrRN: (Region Style: header) 
GisMapRN: (Region Style: messageComponentLayout) 
messageLayout1(type:) 
MapRawText (type: rawText 
 
Behind the GisMapRN I have added a Controller. 
 
In the Controller I do the next: 
 
..... 
public void processRequest(OAPageContext oapagecontext, OAWebBean oawebbean) 
{ 
super.processRequest(oapagecontext, oawebbean); 
prepareEsriMap(oapagecontext, oawebbean); 
} 
public void processFormRequest(OAPageContext oapagecontext, OAWebBean oawebbean) 
{ 
super.processFormRequest(oapagecontext, oawebbean); 
} 
private void prepareEsriMap(OAPageContext oapagecontext, OAWebBean oawebbean) 
{ 
String project_set_id = oapagecontext.getParameter("paProjectSetId"); 
String url = "OA.jsp?akRegionCode=PA_PROJECT_HOME_LAYOUT&akRegionApplicationId=275&addBreadCrumb=RS&paProjectId=\"+projectId+\"&retainAM=Y"; 
OAUrl urlObject = new OAUrl(url); 
OARenderingContext renderingcontext = oapagecontext.getRenderingContext(); 
String destURL = urlObject.createURL(renderingcontext); 
StringBuffer stringbuffer = new StringBuffer(); 
stringbuffer.append("<HTML xmlns='http://www.w3.org/1999/xhtml' xmlns:v='urn:schemas-microsoft-com:vml'> \n"); 
stringbuffer.append(" <HEAD> \n"); 
stringbuffer.append(" <meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\"/> \n"); 
stringbuffer.append(" <script type=\"text/javascript\" src=\"http://serverapi.arcgisonline.com/jsapi/arcgis/?v=1\"></script> \n"); 
stringbuffer.append(" <script type=\"text/javascript\" src=\"http://dbr4004v.dbr.agro.nl:8080/ebs/javascript/ebs.js\"></script> \n"); 
stringbuffer.append(" <script type=\"text/javascript\"> \n"); 
stringbuffer.append(" function getProject(projectId) { \n"); 
stringbuffer.append(" window.location=\"").append(destURL).append("\"; \n"); 
stringbuffer.append(" } \n"); 
stringbuffer.append(" </script> \n"); 
stringbuffer.append(" </HEAD> \n"); 
stringbuffer.append(" <BODY> \n"); 
stringbuffer.append(" <input type=\"button\" value=\"Show Projects\" onclick=\"zoomToProjectSet(").append(project_set_id).append(");\"/> \n"); 
stringbuffer.append(" \n"); 
stringbuffer.append(" <div id=\"mapDiv\" style=\"width:1000px; height:500px; border:1px solid #000;\"></div> \n"); 
stringbuffer.append(" </BODY> \n"); 
stringbuffer.append("</HTML> \n"); 
..... 
 
If I navigate via responsibility: Project Super User and via the path: Project Sets > Click one of the Project Set Name > then I can see the adapted Project Sets screen with stadard Projects region and below that the new added ESRI map region. 
The new region has a button to zoom in in the ESRI map and the ESRI map itself with some geometry information. 
The functionality of button is as working expected: (zoomToProjectSet(project_set_id) ). 
But when I click one of the geometry region to call for example Project Overview screen then I get the error message: 
"You have insufficient privileges for the current operation. Please contact your System Administrator.
You cannot run a page which is not SelfSecured when the MAC fails."
 
It is remarkable if I click the Project Name links in the Project Overview screen these have all different oas text 
OA_HTML/OA.jsp?_rc=PA_PROJECT_HOME_LAYOUT&_ri=275&addBreadCrumb=RS&paProjectId=4832&_ti=2094430068&oapc=3&oas=l305LKdSwzg9iJqy8q00ew.. 
OA_HTML/OA.jsp?_rc=PA_PROJECT_HOME_LAYOUT&_ri=275&addBreadCrumb=RS&paProjectId=4869&_ti=2094430068&oapc=3&oas=xO_5dM4O-mKT38E1En5Msg..

When click the ESRI map region which try to reproduce same action as Project Name links in the Project Overview screen then I get almost the same URL but the value for oas is same for all different paProjectId's: 
OA_HTML/OA.jsp?_rc=PA_PROJECT_HOME_LAYOUT&_ri=275&addBreadCrumb=RS&paProjectId=4832&_ti=2094430068&oapc=3&oas=7XDzPk3HK9fR2emiJYeO9Q.. 
OA_HTML/OA.jsp?_rc=PA_PROJECT_HOME_LAYOUT&_ri=275&addBreadCrumb=RS&paProjectId=4869&_ti=2094430068&oapc=3&oas=7XDzPk3HK9fR2emiJYeO9Q..

I know the issue lie on oas value but I could NOT get the right value for this parameter in the above URLs. 
 
Has someone some idea how to solve this issue. 
 
Many thanks,

Cafer,
If you see old threads i have explained that the three profiles Kali mentioned... is basically to bypass the MAC key validation in Apps.If you don't want to change these profiles, you would need to use bound values api's to attach js function with onclick attribute of button.
If you are new to bound values concept, this is what u need to do:
1)In process request, use
pagecontext.putJavaScriptFunction();
2)Make a PVO with transient attribute say x whose query can be like
select 'javascript:<function name>' from dual
3) Use bound value view object api to attach with ON_CLICK_ATTR of button.

Penryn Macs having issues?

Okay,
I have finally decided to move to Mac OS and buy a MacBook Pro.
* iWork '08 preinstalled
* Accessory Kit
* MacBook Pro 15-inch Widescreen Display
* 2.4GHz Intel Core 2 Duo
* 200GB Serial ATA Drive @ 7200 rpm
* Backlit Keyboard/Mac OS - U.S. English
* SuperDrive 8x (DVD±R DL/DVD±RW/CD-RW)
* 2GB 667MHz DDR2 SDRAM - 2x1GB
* Apple Remote
* NVIDIA GeForce 8600M GT with 256MB
I am extremely exited. But before i order, i was wondering if I should expect allot of problems? About 2 years ago, my friend bought a macbook and had to have it replaced 5 times. How have the Penryn macs been?
This will l be my first Mac ever so I am hoping to have a good transition to the mac world:)
Thanks,
Mac Zac.

Hi Zac.
Let me be the first to say, welcome to the light side!
Regarding the Penryn Macs: No, there are not so many issues that you should hold off buying one. If you browse the forums here you'll find lots of people running into problems. But remember that all the millions of people that DON'T have problems don't come here to tell you everything's working fine. For the vast majority of people, Macs work seamlessly, day in and day out.
Of course, like all technology products, sometimes Macs have issues. They are made out of the same silicon and chips as other computers and, like those other computers, components can fail or go bad. That's just life. The good news is: it's rare.
Likewise, Leopard is running extremely well for the vast majority of people. To be sure, there are a few small issues affecting small groups of people. Some folks are having wireless troubles, others are seeing some typing issues after a keyboard firmware update, for some folks iTunes is locking up while browsing cover flow. But, again, these issues don't appear to be too widespread and I would certainly not hold off buying a Mac because of them. You can bet that Apple engineers are all over the issues and they'll be resolved soon.
To sum up: the state of the Mac world is fantastic. Like everything else in life, it's not perfect. But it's as close as you'll get with a computer! My advice is to pull the trigger and enjoy the switch! And I'll put my money where my mouth is as well: my $3,000 Penryn MacBook Pro arrives tomorrow morning.

MAC Flapping Issue

Dear Folks,
I am working with a IT organization as network administrator, at client site we are getting the MAC FLAPPING issue since 1 month, due to that some time it completely down my whole network. Scenario is like that, we are using Ruckus AP and Zone director as a WLAN controller which is directly conecteted with our core switch. Rest of indoor AP's are connected with Distribute and access switch. Now since 1 month we are getting in core switch below mention notification -

As mentioned in msg 12 & 13 VLAN is our WLAN.
After getting this msg automatically all network goes down, I need to shut down the associated port winch is directly or indirectly connected with AP, and after some time it will work properly.
Now I need some mechanism which can be block the duplicate source mac address to preventing from this kind of scenario.

Shekhar

Hi Devils,
Answer is in below -
1. Are those MAC addresses actual Wireless Hosts? i.e have you traced them?
= Yes, those are actual wireless MAC add, I have check in zone director controller.
2. Are the SSID's set to tunnel?
=No
3. Do you have one ZoneDirector or two?
=Two, both of them are connected with core switch.
I have been confirmed about that if wireless users are roaming between two AP or more it will appear the same error msg, now what would be the solution. ????
What extly the solution is?>
Where should i implement the solution on switch or zone director?
Please suggest!!!!!

Server certificate verification failed: issuer is not trusted

Tried to sign in to a couple of websites lately and got this message:
Server certificate verification failed: issuer is not trusted
What is going on and how do you fix?

hello, unfortunately this is an issue caused by the website, which uses an intermediary certificate but doesn't properly [https://www.ssllabs.com/ssltest/analyze.html?d=https%3A%2F%2Fphp.net%2F&hideResults=on implement a trusted path to the root certificate authority].
in order to work around that you'd have to manually install the missing certificate and trust it to verify websites in firefox: https://ssl-tools.net/certificates/a1e08f9a6a21691dc96bc3b9fa59a7cadd6d4cc4.pem

Mac fails to conect to wireless

My MAC fails to connect to my WLAN when I boot up, if I refresh it then it will connect. Any thoughts!!!

Give us some more information on your WLAN router make, Wireless security options and more detail about the way you've set up the connection.
Other than that I would be shooting in the dark trying to assist you 100%.
One small thought, if you keep getting signal drop outs, the range between your Mac (iMac?) and router may be being impeded by another WIFI signal or walls/copper cabling. This may lead to the killing of your connection.
....I will await more information from you so we can get to the truth of the problem.

MAC address issue----Spearman

Saw your comments on this in the post about the 1.9 bios for neo2platty ....
I can confirm that My MAC address issue was caused by the bios that you sited in your comments....all F's were written to My nvidia lan too...
only solution from what I have read is too rma it...'bummer'
just thought You would like to know.... Your not alone

I had the same problem yesterday and after many hours searching the web I ended up with this post that made me really desperate... But I didn't give up and while trying a new bios flash because of random crashes when in the bios, I noticed the obvious: you can change the MAC address when flashing
use the last version of the dos flasher with the parameters /nvmac:xxxxxxxxxxxx/wb after the name of the bios file; it's explained if you ask the help with the /help parameter. You can find the mac address on a stick on the parallel port.

I am having the same problem but cannot get anything but the actual phone to work. I have a unlocked 3GS running 6.0 (what was I thinking?). No data whatsoever, no texting, no visual voicemail. I simply cannot access the APN settings. I have tried sim swap, I have tried APN changers. I have been on the phone with ST tech support for hours and hours. I have tried to get the answers from a "genius". I am stuck and looking at Android devices, but would really like to keep using the iphone with Straight Talk.

Spanning Tree and Admin mac address issues srw2048

Ok, I have a somewhat complex problem and hopefully someone may shed some light or have an idea as to whats wrong.
First the scenario:
I have two Cisco Cat 6509's etherchanneled to each other via two fiber cables. One of these is the STP/RSTP root. I have two SRW2048's.. one trunked to each of these 6509 switches. There is also a trunk between the SRW2048's. All this is to create a redundant topology so that if one of the switches fail's the others can still forward packets to each other. Of course the scenario described is in fact a loop that should be handled by STP/RSTP. I have RSTP enabled on all the switches in the scenario (PV RSTP on the cisco switches as they only do Cisco's brand of per vlan spanning tree). There are 3 vlan's configured on each of the srw2048's (2,55,96). There are corresponding vlan's also on the 6509's. I have put the srw2048's management interface into vlan 2.
The problem:
I need to forward packets between the srw2048's primarily and only use the 6509 that is not the root when a failure happens. I have configured the non-root 6509's spanning tree cost on the etherchannel to be higher then the alternate path through the srw's to the root. I can hook everything up and view the spanning tree and see that the srw2048's interface that goes to the non-root 6509 is blocked, and all other interfaces on the other switches are forwarding. I can in fact ping and get to the admin interface on all the switches. Then for some strange reason the admin interface of the srw2048 plugged into the non-root 6509 stops responding. If I disable either the interface its plugged into on the 6509 or the other srw2048 everything starts working again. Sometimes it responds after many failures for no apparent reason. I looked into the mac-address table on the 6509's and they are conflicting, pointing to each other for the mac-address of the broken srw2048. When I clear the mac-table the admin port comes back for about 5 seconds then again goes dark. When reviewing mac-table on the 6509's they are back to pointing to each other. The odd thing (although I haven't confirmed this completely) is that hosts placed into vlan 2 on that same srw2048 seem to work fine. If there was an STP loop or something misconfigured, I would expect it to effect any host in vlan 2 or the other vlan's for that matter on the srw2048 that stops responding. Alas, I am stuck because I need to manage this switch remotely. My only thought is that for some reason even when the STP status is blocked the broken srw2048 is still sending out arp's of its admin interface and bypassing the STP protocol. I have no way to confirm this, but maybe someone has an idea as to what I'm doing wrong, or otherwise offer a solution. For now, I simply removed vlan 2 from the 6509 that the broken srw2048 is plugged into and everything seems fine.
My apologies for such a long post, but this is somewhat complicated. Thanks in advance for any info.

To follow up, I had a ticket open with Linksys about this for about 3 months with no resolution. I submitted packet captures, stp outputs, etc and no luck. I gave up and basically had to revert to a manual failover for redundancy. It's no perfect or fast, but it works every time.
Unless linksys issues a firmware upgrade with this as a fix, I doubt we will be able to ever resolve this on our own.

Does anybody know if there is an issue with the Calendar not syncing with iCloud. Everything in Outlook will sync using iCloud except the Calendar.iCal has no issue, just Calendar from Outlook.

Hi Robert,
I found a KB for your reference:
