Fall back of master to slave
we have uccx 7.0, the master server (publisher) falls back to slave as soon as we have 20 agents in queue. And agents keep on logging out as soon as we have around 20 calls in queue again; what could be the posssible reason for it. We have enough licenses & CTI ports to handle the queue calls.
Hi
You would need to review the logs (MIVR/MCVD logs) to determine the cause of this failure:
They are in subfolders of c:\program files\wfavvid\log
Feel free to post them up.

As I asked in my question about "falling back" to ver 5 of FF. What if I download to ver 6 and decide I would rather remain with Firefox ver 5. In other words if I try the newest version of FF (6) and find it to much of a difference can I re-download FF v. 5? I'm kind of set with my current version and don't like the idea of changing to a newer version unless I have a fallback option.
I will be waiting your answer. thanks---Ed R.Download a new copy of the Firefox program: http://www.mozilla.com/firefox/all.html
Trash the current Firefox application to do a clean reinstall.
Install the new version that you have downloaded.

Is it possible to only allow HD content when HDCP is present, otherwise fall back to SD?
For any of the proposed ideas here, you will have to package your content twice, where each stream would require its own license:
1 package for SD bitrates
1 package for HD bitrates
[ Try to play & react if necessary ]
When the user wants to play HD content, attempt to do a license acquisition for the HD stream. If it fails with an error code indicating that the device doesn't not have the needed output protection requirements (DRMErrorEvent 3338 – 3342), the client would then fall back and play the SD stream, which would trigger a license acquisition of a license that doesn't require Output Protection enabled.
[ License Preview ]
When the user wants to play content, perform a "License Preview" of the HD stream to determine if the license can be consumed & enforced by the device (DRMManager.loadPreviewVoucher()). If the result of loading this Preview license fails with a DRM Error event around Output Protection requirements (#3338-3342), then play the SD stream.
[ Leverage an existing front-load license request that you're using to preemptively initialize the DRM system ]
This is similar to "License Preview", but attempts to front-load that check and retain the result for later use.
In our whitepaper to optimize "start to playback" experience (http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/video/pdfs/start-to-p layback-adobe-access.pdf), one of the things we recommended was to front-load a license acquisition on a non-existent content very early in the user workflow (Optimization #2). Doing this would initialize the DRM system so that when the real license acquisition happened later on, Adobe Access would already be primed.
To take this a step further, if you have this in place, since you already are doing a license acquisition ahead of time, you could use a policy that requires Output Protection. In your client, when it attempts to acquire a license, it can record whether or not the operation was successful. If it was successful, the client could have logic to show HD content options to the viewer. If the acquisition was unsuccessful, then the client could restrict viewing to only the SD content.ok great thats what i thought

After upgrading to FF 4.0 I am not able to access or display my bank statements or credit card statements. I have a laptop running Win 7 and a desktop running Win XP and have same problem on both. Statements are in Adobe PDF. Upgraded Adobe to vers. 10 at banks suggestion but did not help. I have now fallen back to FF 3.6 on both PC's, and it now works on both PC's, one running Adobe Reader 9 and the other running Adobe 10.
Additionally, my email provider (bbwi.net) "Squirrel Mail" times out and logs me off every 15 minutes or so in FF 4.0, even when I am actively composing mail. Falling back to FF 3.6 also fixed this problem1st, you will not be able to activate your PPro1.5 on ANY new computer, see next link for the special version you MUST use

Error when installing Lion on empy HD: "Couldn't find app store version, falling back to hardcoded"
I've run in to a problem that is making me tear the hair from my head. I'm hoping for your help!
Short story:
I'm trying to install OS X Lion on my 27" iMac.
I've erased the HD using Disc Tool in recovery.
HD shows no errors.
I've tried Internet Recovery (it loads up, but wont start the installation)
I've tried creating a recovery usb on another similar iMac, and use it on this. Same error, only differance is it keeps "loading" when installing, but nothing happens. Same error in log.
When I try to start the Reinstall I get an error in the installation log that goes something like this:
Install Mac OS X Lion[354:9c03] Couldn't find app store version, falling back to hardcoded
Can not connect to /var/run/systemkeychaincheck.socket: No such file or directory
Apple Care suggested:
Trying another network (doesn't work).
Install with the original Snow Leopard DVD first, then upgrade (can't do that, the DVD is lost and a DVD from another friend is not working)
What can I do to get around this error?
Someone suggested buying a usb with Snow Leopard from the apple store. Do I really have to buy a NEW operating system because the recovery doesn't work? Would I have to pay to upgrade to Lion again?Follow AppleCare's instructions on re-installing Snow Leopard and re-installing Lion. Your friends disc won't work because the discs are machine specific. You will have to get a replacement set of your original Install Discs from AppleCare for a nominal cost.

Upgraded to 6.0.2, IBM Lotus Notes doesn't work correctly. Can I fall back to a previous FireFox?
I've been using previous versions of FireFox for years on XP machines. Recently bought a Win-7 machine and upgraded both to FF 6.0.2. I can't get scroll bars on the side when using my company's IBM Lotus Domino. I've had to drop back to IE, which I do not like. Is there some way to fall back to an earlier version of FF? The site with the problem requires UID/PW to login, so I can't show you the problem I'm experiencing.
A possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.

hi guys,
i am confused about the master and slave realtionship in ospf. any one can explain it to me in detail.Hello Pankaj,
The Master and Slave in OSPF are a slightly confusing concept but the idea behind it is quite simple.
When two routers decide to become fully adjacent, they must synchronize their LSDBs. OSPF tries to optimize this: the routers first exchange only the list of entries in their LSDBs. Each router compares the received list to the list of items in its own database, and if it finds that an LSA is missing or is older than one the neighbor knows about, it requests it from the neighbor afterwards. This way, both routers transmit only the missing or updated LSAs, not the entire LSDBs.
The list of LSDB entries is carried in Database Description (DBD) packets. Naturally, when routers exchange DBD packets, they must be sure all of them have been properly received by the neighbor, so some sort of acknowledgements must be used. There is a problem here, however: the only packets in OSPF used to carry acknowledgements are LSAck packets, but they can only be used to acknowledge LSU packets (more precisely, individual LSAs carried in LSU packets), not DBD packets. How shall the acknowledgements of DBD packets be accomplished, then?
OSPF uses a polling style of communication with the DBD packets. DBD packets themselves have sequence numbers used for sequencing and acknowledgement purposes. One of the two routers that are in the synchronization phase will be the one responsible for polling the other (i.e. calling it out it to send another piece of information if it has any), each time with an incremented sequence number. This is the Master role. The other router will only be allowed to respond to a DBD poll, never send any DBD packet without being polled immediately before, and the response DBD packet must carry the sequence number of the Master's DBD poll packet. This is the Slave role. The Slave must respond to each Master's DBD packet even if it has no more LSDB entries to advertise; in that case, the DBD response body will be empty.
So during the DBD exchange, the Master sends DBD packets to Slave, incrementing the sequence number by one in each round. The Slave waits for DBD packets from the Master and only responds to them, and each response carries the sequence number from the last received Master's DBD packet that was used to poll the Slave. Remember: a Slave must not send DBD packets on its own, only as responses to DBD packets received from the Master, and the sequence number of the Slave's response DBD packet must be set to the Master's poll DBD packet.
While I call the DBD packets as "polls" and "responses" here for the sake of clarity, the DBD packets do not have this distinction indicated explicitly. Any DBD packet sent from the Master, either with a body carrying a list of LSAs or an empty body, is a poll. Any DBD packet sent from the Slave, again either with a non-empty or empty body, is a response. A DBD packet can have an empty body if the router needs to send a DBD packet to the neighbor (either from Master to repeatedly poll the Slave, or from the Slave to confirm the arrival of the DBD packet from the Master) but has no more LSDB entries to advertise itself.
There are two issues with this simple procedure. First, there is the issue of who out of two synchronizing routers will be the Master and who will be the Slave. This is resolved during the ExStart phase: both routers initially treat themselves as Master routers, and send DBD packets with random initial sequence numbers to each other, indicating the MS flag (Master) in their header. As they do this, the router with the lower RouterID moves to the Slave role, while the router with the higher RouterID remains in the Master role. The ExStart phase is basically finished after establishing the router's role in the synchronizing pair; at most two DBD packets are needed for that, one from each router. The Exchange phase then lasts until routers have exchanged the entire list of their LSDB entries using DBD packets.
The second issue is more subtle: how should the Master know whether the Slave needs to be polled further? Clearly, a situation may arise when the Master's LSDB is empty or smaller than the Slave's, and the Master will need to send fewer DBDs than the Slave to list all its LSDB contents. As the Slave can not send a DBD packet on its own, it somehow needs to tell the Master to poll it again. This is accomplished by another flag in DBD packet header, the M (More) flag. If a Slave replies to the Master's DBD packet with its own DBD packet and the M flag set, the Master knows the Slave needs to be polled again. The Master will stop polling the Slave after the last DBD packet fom the Slave has the M flag cleared.
The RFC 2328 has a nice ASCIIart graph of the adjacency coming up:
+---+ +---+
|RT1| |RT2|
+---+ +---+
Down Down
Hello(DR=0,seen=0)
------------------------------>
Hello (DR=RT2,seen=RT1,...) Init
<------------------------------
ExStart D-D (Seq=x,I,M,Master)
------------------------------>
D-D (Seq=y,I,M,Master) ExStart
<------------------------------
Exchange D-D (Seq=y,M,Slave)
------------------------------>
D-D (Seq=y+1,M,Master) Exchange
<------------------------------
D-D (Seq=y+1,M,Slave)
------------------------------>
D-D (Seq=y+n, Master)
<------------------------------
D-D (Seq=y+n, Slave)
Loading ------------------------------>
LS Request Full
------------------------------>
LS Update
<------------------------------
LS Request
------------------------------>
LS Update
<------------------------------
Full
The I flag here is another flag in DBD headers called the Init flag, and is set only on initial DBD packets in the ExStart phase. If the router has established its Master or Slave role, it clears the I flag. This one is not really that important right now.
The Master/Slave relationship is built and relevant only during the initial LSDB synchronization when a new adjacency is being established. After the two routers go past the Exchange state, DBD packets are not used anymore, and the whole Master/Slave relationship is forgotten. Remember: Master/Slave is relevant only to DBD packets, and DBD packets are used only in ExStart/Exchange phases. Outside of these states, there are no DBD packets used, hence no Master/Slave relationships exist.
If there are, say, four routers, R1 till R4, connected to the same switch and run OSPF, during the OSPF bootup, there will be 5 temporary Master/Slave relationship built and torn down afterwards:
between the DR and BDR as they synchronize (assume those routers are R1 and R2)
between R3 and DR
between R3 and BDR
between R4 and DR
between R4 and BDR
Notice the Master/Slave relationship existed between those routers that went through ExStart and Exchange into the Full state. Also keep in mind that in the Full state, there are no more Master/Slave relationship present - they were only needed because of the specific needs of the DBD packet exchange.
Does this make the issue a little more clear? Please feel welcome to ask further!
Best regards,
Peter -

eight thermo.JPG 106 KBDear Nicholas,
My first advise would be to check the examples on master-slave patterns, and run them step by step, looking at what the data does...
In a master-slave system, you use the queue to pass data from the master to the slave. You're not passing data in the queue... in stead, you're passing data using local variables, which you should NOT do...
In the top loops, you should attach the temp array to the enqueue element. In the bottom loop, you should remove the temp local, and instead get your data from the dequeue vi.
Also, you have to create a queue with the proper variable. You can create a queue from any variable type, but it has to know beforehand, and the init vi.
Assuming you want to queue the temp array, you're basic structure should look like this:
It does help if you add your own code, so we can easier edit it for you... Otherwise we need to use photoshop on your design...

Master and Slave configurations
Hi
I am currently wondering why my master and slave configurations dan't work. I have the Rev. B mother board and I set the jumpers to the right spots. I am trying to get my CD Burner to work with my regular CD Rom on the same wire.Jarrett,
my experience with my 3 Beige G#'s (1 desktop and two towers), tells me that a master/slave configuration with two optical drives is not really possible/compatible.
As a matter of fact, I had to opt for the following solution:
- Sony 52X burner installed in the CD bay;
- Iomega 52X USB burner on the USB PCI card.
I also had a huge number of problems with the master/slave configuration of drives, and it only worked with certain brands of drives.
For instance, two WD drives would not get along in the same case (data corruption like there's no tomorrow.....)
I ended up having a WD and a Seagate, which still get a long nowadays in my B&W G3.
To give you some more curious feedback on the bad habits of the Beige machines........my old G3 now sits in my son's room.
Believe it or not, I had to remove the Sony burner, as the computer would not boot from it, at all.
It would read and play CD's but it would not boot, in the most standard of the configurations:
- CD Burner Master and 1 IDE drive as a slave;
- SCSI card with SCSI drive;
I replaced the burner with the APPLE CD-drive form my B&W, and the system started working and booting like magic (I swear....I did not change anything else).
It boils down to trying and experimenting. I spent countless hours with those machines trying to figure out why the same configuration working on my Beige minitower would not work on my daughter's Beige minitower, exactly identical machines, both with rev. B boards.
Hope this can help.

Can this router fall back to 3g if 4g is not available?
We recently purchased this router to work remotely. However some of the places we are at have only 3G service. Phone seem to work with 3G receiving data, but our 4G LTE router will not connect. I've looked through the setting in the router, but can't seem to find anyway to have it fall back to 3G if 4G isn't available.
The VZW 4G LTE router does not appear to have tie-ins to the old GSM (3G Only) network. It may be able to fall back to 3G while connected to the new SIM card network, but there are no ways to control this behavior from the User Guide.
If you are only within range of a 3G only signal then I would not expect this device to work. The silver lining here is that 4G LTE is supposed to replace the entire 3G Verizon footprint. Eventually anywhere that you have 3G only service will have a 4G LTE signal and your router will be able to work.
If you need an immediate solution from VZW it would have to be to swap the 4G LTE router and go with a Mobile Hotspot instead since they can connect to 3G only at this time. -
Hi,
i have two WLC 4402 with same ios 4.2.99.0
& configured fail over based on below link
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a008064a294.shtml#c5
AP failover occurred but the fall back option like primary WLC comes up it does not register with primary all the ap still in secondary. I enable Fall back option also as per the document.
could you guide me how i can troubleshoot this issue..
Thanks..hi,
the meaning is the secondary WLC is not realsing the IP's for client eventhough the SSId match with extract DHCP scope. DHCP scope is not overlap...
Important.
Primary box is new one with 4.2.99 but the old box had 4.1.x b4 the failover the old box was working & released the DHCP scope for the client. Once we upgraded the old box with 4.2.99 (Failover we need to have both the box with same version) even it is not releasing the DHCP scope if i used as standalone device also.
My doubt is
1. New box if i used as a stand alone it is releasing the DHCP scope for the client
2. Both the new & old box has the same configuration
3. If i used old box as a stand alone device why it is not releasing the DHCP scope (with the same IOS & configuration working perfectly on new box)
4. This issue occured after upgrade the IOS on old box.
Can anyone help me out at earliest.

I would like to configure the fall back agents for the 'Manager of Manager' shopping cart approval process to be the originating users manager. Not all departments in our organization have multiple levels of management but we would still like a second level of approval when the shopping cart amount is greater than 50K. It works when there are multiple managers defined in the org structure, but I get an Agent Determination error when there is only one manager defined.
Is there a quick way to do this?
Thanks
JonSaravanan,
I figured out how to get it to determine the originators first level manager and direct the work item there.
The business requirement is for carts over $50K there needs to be a director level approval. In most cases in our organization, the director is the second level manager so the manager of manager agent determination process works perfect. However some departments have one manager/director and only three employees so there is no organizational second level of approval that can be used. In these cases, the manager is the director and needs to approve the cart twice. Using the fall back agent method seems the best approach for these occurances.

ISE admin , PSN and monitoring node fail-over and fall back scenario
Hi Experts,
I have question about ISE failover .
I have two ISE appliaces in two different location . I am trying to understand the fail-over scenario and fall-back scenario
I have gone through document as well however still not clear.
my Primary ISE server would have primary admin role , primary monitoring node and secondary ISE would have secondary admin and secondary monitoring role .
In case of primary ISE appliance failure , I will have to login into secondary ISE node and make admin role as primary but how about if primary ISE comes back ? what would be scenario ?
during the primary failure will there any impact with users for authentication ? as far as PSN is available from secondary , it should work ...right ?
and what is the actual method to promote the secondary ISE admin node to primary ? do i have to even manually make monitoring node role changes ?
will i have to reboot the secondary ISE after promoting admin role to primary ?We have the same set up across an OTV link and have tested this scenario out multiple times. You don't have to do anything if communication is broken between the prim and secondary nodes. The secondary will automatically start authenticating devices that it is in contact with. If you promote the secondary to primary after the link is broke it will assume the primary role when the link is restored and force the former primary nodes to secondary.

Fall back systemwhen multiple SAP systems trying to acheive SSO with BOEXI
Friends,
I need a small clarification on ' SSO between BOE XI 3.1 and SAP BI 7' Scenario,
Say when multiple users log on through their SAP EP Portals or Netwever Portals, they use their tokens generated by their respective EP portals which are passed through the 'Web application server' hosting BOE environment.
1) When its a Single EP portal , we can have have a fall back system. when we register its logical name in the CMC of BOE Environment , a typical SNC.But what's the fall back system for multiple SAP systems?
2) Also Whether there are any pit falls via token method when more than one SAP system communicating to BOE?
3) Do we have any documentation for this?
Thanks ,
Sivakanth.Hi Sivakanth,
the normal scenario for SSO is the following:
When you said ''back end system ', i did not get it.
Enterprise Portal -
(iView)-------> BOE -
> SAP BI <- This is your backend system
Well Could I define more than one logical name there in SNC tab of CMC.?
I assume you have the following situation:
(EP1, EP2, EP3) -
> BOE -
> (SAP BI 1, SAP BI 2, SAP BI n)
You can define more than one entitlement systems in the BOE CMC and also configure for each one of them for SNC. Please note that we are talking about server trust and NOT client trust here. It is all about letting your sap system and the boe system trust each other. If you have your portal with client SNC configured (ie. the user logs using a certificate and an SAP logon ticket is created) it is NOT necessary to configure SNC in the CMC (Please refer to the section "Configuring SAP Server-Side Trust" in the installation guide for the integration kit for SAP) side.
Back to the SSO scenario now: When a user connects from an enterprise portal on the BOE system the logon ticket, generated from the portal, is forwarded to the back-end system, which is defined in the portal iView the user is currently navigating through. If it is a Crystal Enterprise iView then you just have to select the appropriate system alias of your back-end system in the System drop down menu when creating the iView. For URL iViews you must utilize the relevant openDocument parameters. If you do not define anything at all when creating the iView then BOE tries to authenticate the logon ticket against the SAP BI system you selected to be the default one in the "Authentication->SAP->Options" tab of the CMC.
If what you want is just to distribute the load between your SAP back-end systems then you should consider utilizing an SAP cluster for your pursposes. As explained before BOE will not distribute the requests evenly on the back-end systems. It will try to contact either the system defined in the request (iView) or the default system. To be honest I am not sure what happens if the explicitely defined system is not available but I think that an error message is what you should expect then. I do not think that in this case the BOE system tries to use the system defined as default.
Another part is what kind of security is defined in BEX querys..as i read from SAP IK guide, we can import all the roles which are defined at ABAB level.
Will there be any security threats to SAP data via this method.
It is true that you can import all roles in your BOE system. But keep the following four things in mind:
1) You can restrict on the BOE side the users which are authorized to logon in the CMC and import the roles (normally only the BOE administrator is authorized to do this)
2) Importing a role means that an SAP user can try to logon the BOE. Still the logon process can only be succesfull only if the SAP user has special authorization on the SAP side (Please check the Appendix "Authorizations" in the installation guide of the integration Kit for SAP.
3) You can restrict the access to data by assigning authorizations only for specific infoareas/infoproviders. In order to partially restrict data access in a given infoprovider (e.g infocube or multiprovider) you can utilize authorization variables in your BW query.
4) You can further restrict access on specific reports either on the BOE side or on the portal side (by rstricting access to the defined iViews).
For sure you must invest some time to define and implement your security concept.
More over could you please answer other 2 questions in my original question.
2) Also Whether there are any pit falls via token method when more than one SAP system communicating to BOE?
3) Do we have any documentation for this?
2) As long as your portals, the back-end systems and your BOE system are configured correctly for SSO this should not be a problem. Well just a tip based on my experience: be sure to use full qualified domain names for your systems in the iView definitions. And do not forget SSO works only if all systems are in the same domain.
3) As said in my previous posting the netweaver documentation regadring SSO setup maybe interesting for you. As far as I know the multiple systems scenario is not contained explicitely in any official BOBJ documentation. I assume that you already went through the installation guide for the integration kit for SAP.
Please tell me if you have a completely different scenario in mind

Stratos
