WAAS Mobile HA between 2 Data Centres

We have to deploy WAAS Mobile between 2 Data Centres, with remote user connecting to either DC across VPN & then connecting to a local WAAS Mobile server. We are trying to understand the best way to configure this from the available documentation on CCO.
We are a bit confused re the role of the WAAS Mobile Manager Server.
Is this similar to the role of Central Manager on normal WAAS, i.e configuration/management etc, or does it have any function in the selection of the server a client will connect to.
Regarding HA & Load balancing of the connections between the Data Centres, this is how we think we should deploy it!
Deploy a Server Farm at each DC & use the Latency based method of farm selection. This way the client should connect to the local server farm, based on which DC the VPN connects to?
Is this correct, has anyone deployed WAAS mobile in this way or have any advice?
Thanks
Colin

Fabricpath is L2; not related to the L3 technology you want to use; if VRF are in use you can just use VLANs which is described in your first scenario : "use 2 routers with VRF lite configuration in each DC, then dot1q on the trunk through the Fabric Path"

FabricPath & Layer-3 VPNs (VRF) between 2 Data Centres

Hi there,
I'm looking at deploying FabricPath for layer-2 extension between 2 Data Centres.
We also have the requirement for providing layer-3 services between the 2 DC, as in Layer-3 VPN (MPLS VPN).
The alternative technology was MPLS, with full blown Layer-3 VPN, and Layer-2 VPNs through AToM or VPLS.
My question is, how can we provide VRF support over FabricPath?? Can we use 2 routers with VRF lite configuration in each DC, then dot1q on the trunk through the Fabric Path? Or just VRF Lite on the layer-3 terminating routers, with a specific VLAN for interconnecting the different VRFs?
Thanks,

WAAS Mobile Server Time/Date incorrect

Hi,
I cannot seem to find where I configured the time/date settings for the WAAS mobile server.
The Win 2008 server that the Mobile server is installed on has the right time, but the WAAS mobile server itself does not.
At the moment it is using GMT.
Can anyone help?
Thanks

Where do you see this GMT timestamp? It may be by design.

How to access a Network Share between two servers in same data centre

I have two dedicated servers (both Windows 2012 Server) hosted in a data centre somewhere. I want to share a folder on one server with the other server, but it's obviously not as straight forward as one might think. My servers are called "Maximus"
and "Apprentice".
On Maximus I shared a folder by right clicking on it and choosing "Share with... / Specific People", I then typed in the name of a local user account which also exists on Apprentice with the same name and password. (so each server has a local
user account with the same name and password).
So then on Apprentice, I was hoping I could access the share (while being logged in as this user with whom the folder was shared) by simply typing "\\ipaddress\sharename" into the address bar in file explorer. Unfortunately it comes
back with "Windows can not access [ip address]".
Now, I do have a website setup on the IP address for Maximus. This is actually the reason I want to create this share. I need the second server for load balancing and need to share IIS config as well as the website itself. (So I will need
two shares eventually, but for now I'm just trying to get one to work). I don't know if the fact that the ip address is pointing to the website is causing me problems here or if it's something else.
Are there any network gurus out there who can tell me what the issue is and how to resolve it?

I can ping both servers in either direction, but I believe I may have found the problem. Apparently my host is blocking port 445 which Windows wants to use to connect to the share and they will not unblock it.
Is there a way to connect to the share through a different port?
To my knowledge, you cannot change the port. However, you can try disabling your security software for testing. If this fixes the problem then you need to adjust your security software configuration so that traffic on this port is not blocked or filtered.

Data Centre - Moving between

Hi,
I read somewhere "Business Catalyst does have plans to develop functionality that will allow templates to be transferred across data centres, but that is not currently available"
Is this true and does anyone have an idea of whether this is on the agend? E.g within 1 year or more like 5+ years away?
We have a private template that we would like on a local data centre but BC say they can't move it across and in terms of SEO we will be penalised as it's hosted in another country. If BC are working on being able to move then we are happy to wait but if they aren't i'd imagine the cost to recreate it on a new site would be a lot of work. Has anyone done this before?
Thank you

Hi there,
I know that site migration feature was worked on, but never completed. I don't why the development was postponed and when the feature will be released. You're probably looking at 2+ years.
In any case, since you can transfer almost all assets via FTP, you can get 80% of work done that way. The remaining 20% will be modules you have to recreate. and update the module IDs.
Cheers,
Mario

SQL 2012 AlwaysOn Dual Data Centre (an instance in each data centre with a secondary in each other respectively)

Hi, hopefully someone will be able to find my scenario interesting enough to comment on!
We have two instances of SQL, for this example I will call them 'L' and 'J'. We also have two data-centres, for this example I will call them 'D1' and 'D2'. We are attempting to create a new solution and our hardware budget is rather large. The directive
from the company is that they want to be able to run either instance from either data centre. Preferably the primary for each will be seperated, so for example:
Instance 'L' will sit in data centre 'D1' with the ability to move to 'D2', and...
Instance 'J' will sit in data centre 'D2' with the ability to move to 'D1' on request.
My initial idea was to create a 6-node cluster - 3-nodes in each data centre. Let's name these D1-1, D1-2, D1-3 and D2-1, D2-2, D2-3 to signify which data centre they sit in.
'L' could then sit on (for example) D1-1, with the option to move to D1-2 (synchronously), D2-1,D2-2 (a-synchronously)
'J' could sit on D2-3, with D2-2 as a synchronous secondary and D1-3,D1-2 as the asynchronous secondaries.
Our asynchronous secondaries in this solution are our full DR options, our synchronous secondaries are our DR option without moving to another data centre site. The synchronous secondaries will be set up as automatic fail-over partners.
In theory, that may seen like a good approach. But when I took it to the proof of concept stage, we had issues with quorum...
Because there are three nodes at each side of the fence (3 in each data centre), then neither side has the 'majority' (the number of votes required to take control of the cluster). To get around this, we used WSFC with Node and File Share majority - with
the file share sitting in the D1 data centre. Now the D1 data centre has 4 votes in total, and D2 only has 3.
This is a great setup if one of our data centres was defined as the 'primary', but the business requirement is to have two primary data centres, with the ability to fail over to one another.
In the proof of concept, i tested the theory by building the example solution and dropping the connection which divides the two data centres. It caused the data centre with the file share to stay online (as it had the majority), but the other data centre
lost it's availability group listeners. SQL Server stayed online, just not via the AG listener's name - i.e. we could connect to them via their hostnames, rather than the shared 'virtual' name.
So I guess really I'm wondering, did anyone else have any experience of this type of setup? or any adjustments that can be made to the example solution, or the quorum settings in order to provide a nice outcome?

So if all nodes lost connectivity to the fileshare it means that there are a total number of 6 votes visible to each node now. Think of people holding up their hands and each one can see the hand. If the second link between the two sites went down then each
node on each side would only see 3 hands being held up. Since Quorum maximum votes =7, the majority needed to be seen by a node would be 4. So in that scenario, every node would realize it had lost majority and would offline from the cluster.
Remember that quorum maximum (and therefore majority), never changes *unless* YOU change node weight. Failures just mean then is one less vote that can be cast, but the required majority remains the same.
Thanks for the complement btw -very kind! I am presuming by your tag that you might be based in the UK. If so and you are ever nearby, make sure you drop by and say hello! I'll be talking at the
London SQL UG two weeks from today if you are around.

Dual Data Centres 200miles apart - L2 trunking/Gigabit, is this ok?

Hello All,
We've 2 data centres, one primary the other DR, we've also 2 Gigabit fibre links between the 2, 200 miles apart.
To keep the PIX Active/Standby roles across the sites, I'm investigating the idea of linking the 2 datacentres with trunks at L2.
Is this good practice?, I know in the pre-Gigabit days this was frowned upon but these days it would make sense and make design much easier - any thoughts appreciated
Regards Tony

Be careful with spanning tree and L2 links between your primary and DR. If spanning-tree were to have issues at your primary datacentre causing an outage it could also take secondary with it and vice versa.

Waas mobile + waas appliance

Topology
waas mobile client ---------waas appliance---------wan---------waas appliance---------waas mobile server---------------applications/servers
What will happen in this topology? Who is going to perform the acceleration function?
Can waas mobile client/server talk to waas appliance?
Thanks
Joe

Hi Joe,
Waas Mobile and WAAS are going to be both optimizing traffic in this case.
While WAAS mobile will tunneled all the traffic so Optimized data is transmitted over UDP port 1182 and session initiation and control uses TCP port 1182.
WAAS appliance will perform same transparent method, by applying option 33 (0x21) and changing the tcp sequence so both WAE's (dc and remote site) can see each other and apply optimization to the tcp flow.
Since WAAS mobile will have already compressed data initially, when the tcp flow hist WAAS appliance devices I expect that the optimization there will be minimum.
You might consider to have WAAS Mobile next to your VPN hubs, so remote desktop/laptops are able to get optimization when ingress in your network and won't waste WAAS appliances resources which will perform double optimization, first in waas mobile then in waas itself.
Hope the information helps.
Thank you

Replicate File Server from Europe to Singapore data centre

Hi we would like to store 1 tb of blob data in Azure.
We would like to upload the data in London and then have a read only copy of the data be replicated to ideally the Singapore azure data centre.
Is this possible.
thanks

Hi Jonnly,
Irrespective of whether you opt for Geo-redundant storage type OR Read-access geo-redundant storage type for your storage account, the secondary region is determined based on the primary region, and cannot be changed.
You may refer the following link to know the Primary region and their respective Secondary region:
http://msdn.microsoft.com/en-us/library/azure/dn727290.aspx
However, you can create two different storage account in London and Singapore separately and copy the data between two Storage accounts.

Best placement of WAAS mobile

Hi,
What is the best practice? Should WAAS mobile server be installed as close to Internet router as possible? or should WAAS mobile server be installed as close to server farms where the applications are?
Let's say the internet router and server farms are NOT co-located at the same building.
Thanks!
Joe

The WAAS client will intercept all traffic to the networks you specify. See:
http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas_mobile/v3.5/configuration/administration/guide/CiscoWAASMobileAdminGuide_3_5.pdf
page 41, "Configuring Client Networking".
You could add only the ftp servers in Bldg2 in your example. If you had another farm in Bldg1 your could direct traffic towards those servers to another WAAS-Mobile serverfarm.
All traffic send via the WAAS-Mobile server will exit the server (in the default setting) with the IP of the server and using the routing table of the server, so yes you would have to arrange for traffic between the server and the internet.
Alternatively you can define an ip range (as big as the ip range of the clients) to use for outgoing traffic or you can use the original IP of the client (this requires some magic in your network). See page 27.
Best regards, Peter

Working days between two date fields and Changing Factory Calendar

Hi,
I have to calculate working days between two date fields excluding the weekends and public holidays for Switzerland.
I have written the routine using factory calender and its working fine except for two problems now:

Hi Zabina,
Try this function module 'DURATION_DETERMINE'.
Give the factory calendar and unit as DAY

it's good for ideas but implementation a bit different
Oracle Business Intelligence Publisher Report Designer's Guide
This function provides a method to get the difference between two dates in the given locale. The dates need to be in "yyyy-MM-dd" format. This function supports only the Gregorian calendar. The syntax is as follows:
<?xdoxslt:date_diff(‘format’, ‘YYYY-MM-DD’, ‘YYYY-MM-DD’, $_XDOLOCALE, $_XDOTIMEZONE)?>
where
format is the time value for which the difference is to be calculated
Example:
<?xdoxslt:date_diff(‘d’, ‘2006-04-08’, ‘2006-04-01’, $_XDOLOCALE, ‘America/Los_Angeles’)?>

Opening and closing balance between 2 dates

hi.
i am facing a problem while fetching the opening and closing balance for a particular G/L account.
In my program i am entering G/L account for a date range i.e, between two dates and i want opening and closing balance for these 2 date ranges.
So, please tell me is there any function module to fetch opening and closing balance between two dates.
Regards,
ROHINI.K.

Hi Rohini,
             Check this FM :   BAPI_GL_GETGLACCPERIODBALANCES.
If we use this functional module, we will get opening and closing balance of corresponding G/L Acc.
(e.g)
CALL FUNCTION 'BAPI_GL_GETGLACCPERIODBALANCES'
    EXPORTING
      companycode                   = '1000'

Selecting values between 2 dates for an SQL query report region

I have a region where im selecting between 2 dates
select hp.NAME, hp.VALUE, hp.UPDATEDATE, hp.DESCRIPTION, hp.UPDATE_COMMENT, hp.HASH, hp.IDCATEGORY
from HIST_REPORT hr, HIST_PARAM hp
where hp.dbid = hr.dbid and hr.id = :P7_ID and hp.UPDATEDATE between :P7_BDATE and :P7_EDATE
The problem is that if I have a row thats dated today (april 1) and if I set the beginning date (BDATE) to april 1 as well as the ending date (EDATE), no rows show and I would like the april 1 row to show. How can I modify my query to fix this?

and hp.UPDATEDATE between :P7_BDATE
and decode(:P7_EDATE,:P7_BDATE,:P7_EDATE+1,:P7_EDATE)This assumes, though, that the time component of your items is implicitly 00:00.

How to calculate the month difference between two date char. in Query?

Customers would like to see how many months passed between two date type of characteristics (e.g., the month difference between the current date and the scheduled delivery date in the record) and put the result into the column as KF.
We would have to grab the fiscal year/period kind of value and then do the subtraction, e.g., if the current date value is 2/28/2008 and the scheduled delivery date value in the record is 12/01/2007, the correct result should be 2 month difference between these two date values, but could someone here give us the technical light on how to make this happen in query design?
Thanks and we will give you reward points for the correct anwsers!

Hi Kevin,
The Badi is RSR_OLAP_BADI.
You can create an implementation using Transaction SE18.
The implementation is per cube and is defined in the filters.
In the Implementation you have the following methods :
1. Define : Here you will provide the Keyfigure you need as a virtual one.
2. Initilialize : Any Init Function you want to do.
3. Compute. This is called per datarecord and here you can cimpute your value.
Hope this helps.
