Detail on High Availability options for Web Apps

Hi,
I do really struggle to locate actual information on Azure Availability offerings / capabilities...as an Infrastructure Architect it has bugged me for years now with Azure offerings!
Something that simply states the availability within any local DC and options for true HA over 2 or more DC's.
We are moving away from using Web Roles to Web Apps for solutions for our clients. I understand the principles of fault domains, etc. with Web Role requirements for min. of 2 to (mostly) avoid MS update disruption within a single DataCenter, but cannot locate
similar info. with regard to Web Apps.
Really appreciate if someone could point me to some appropriate detail as I've failed....
(Also, cannot find anything on DocumentDB....)
Many Thanks,
Lee

Hi,
High Availability of a running service always comes with a cost, and priorities will be app-specific. If it's the web tier, then you may indeed want to consider hosting in multiple geo's. If it's a backend processing tier, sometimes it's "ok" to
let a service go offline, as long as requests are queued up. If it's the storage system (preventing queueing of messages), perhaps an alternate queue in a different data center could be available for redundancy purposes.
I would request you to check this article:

Hope this information helps.

Compiler Options for Web App

I am working on a training course that deploys a web application to a web server of my choice. I have Tomcat setup and I also have used the embedded server in JDeveloper 10g. There are several exercises that I have partial code written. When I try to deploy the app to test one of the exercises I get compiler errors on other parts of the web app.
Is there any way I can tell the compiler to only compile those things that have changed or still deploy with errors? I was able to get it to deploy by commenting out several pieces of code, but this is not my optimal solution.
Thanks

yes, mod_plsql for Apache (the core of Oracle 9iAS) allows you to make PL/SQL calls from a browser environment and return HTML. the entire Oracle Portal product is written using this mechanism.
learning JSP from scratch, and learning how to manage security, database connections and record sets would be a daunting task. if you want to learn Java, great. it's my favority web language. however, if you have PL/SQL experience and a need to get information to the web, use mod_plsql and generate dynamic content via PL/SQL and the database.
good luck,
rich

How many display options for Web Apps are there?

I know this is going to sound stupid,
But are there only 2 ways to show web apps?
Basically - I want to get links to auto populate on one web app, pulling just links to another web page (this web page is one of the fields in another web app), but automatically updated when the category of the "linked to" web app has another product linked to it.
I know what that reads like!
The only thing is - these are separate web apps.
The alternate/backup view of the first web app looks like this:
Currently - the user has to manually add the links like this:
Which is not ideal - I just want them to dynamically populate on the fly.
Is this possible?
Cheers, Dave

Funny you say that - as the most obvious things appear in your brain immediately after posting a question... Will see how that works...

High Availability Options Without Enterprise Edition

I think I've found the answer to this already but I just wanted to confirm that I'm getting this right. In SQL Server 2012, is there no way to implement a high-availability solution which doesn't require shared storage or use of a deprecated feature without
having Enterprise Edition?
At the moment we have databases hosted on a primary server running Windows Server 2012 Standard and SQL Server 2012 Standard. We have a second, identical server, and the databases are mirrored between the two servers using Database Mirroring.
This works perfectly and meets all of our requirements. The only possible problem is that we're looking at storing documents using FILESTREAM, which isn't available in Mirrored databases.
From what I've read, Database Mirroring is deprecated in SQL Server 2012. High Availability Groups, which sound great, are only available in the Enterprise Edition. This feels like a real kick in the teeth from Microsoft. We're stuck
with either using a deprecated feature (Mirroring), which is only postponing the problem until the end of 2012's life cycle, or laying out significant amounts of money (in the tens of thousands of pounds GBP) to upgrade to Enterprise Edition, which we just
don't have the budget for.
Why couldn't Microsoft continue to offer a high availability option for businesses without deep pockets? Do I have any options I'm not thinking of? Shared storage is not an option (too costly, single point of failure, geographically separated
datacentres).

Thanks for all the feedback.
I was forgetting that even data stored as FILESTREAM would need to be backed up using SQL backups, so I guess that's an issue either way, thank for reminding me, Sebastian.
Geoff, I agree that replication isn't a viable HA solution. FCI has lots going for it, but from what I can make out (and I am just reading up on this now so I could be wrong) requires either shared storage or a third-party tool to move the data from
the Primary server's local storage to the local storage of the Secondaries. It all seems overly complicated when Mirroring does exactly what I need it to do, merrily writing transactions to the mirrors at the same time as the primary databases.
Additionally, whilst you might be right about making the case for Enterprise Edition, it's difficult to make a clear case to non-technical people when we already have a working HA solution and document management. Trying to explain the nuanced advantages
of SQL Server full-text indexing (at present we use a third-party indexing product which stores the index discretely) and simplified querying when the documents are in the same database as their associated data as justification for spending tens of thousands
of pounds is a challenge!
David, that's useful to know, about the disadvantages of using FILESTREAM and how just storing the documents in a VARBINARY(MAX) column might actually give better performance, thank you.

WebCat high availability options?

Calling out to experienced BI architects...
What is the best practice/recommended approach to high availability of the web catalog?
Background:
We just realized that there is a flaw in the design of our clustered, load balanced BI architecture, which consists of the following:
ServerA= OBI Server1 + WebCatalog on local shared Drive
ServerB= OBI Server2
ServerC= JavaHost1/OBI Presentation Server1 pointing to WebCat on ServerA
Server D= JavaHost2/OBI Presentation Server2 pointing to WebCat on ServerA
the flaw is obvious: if ServerA goes down, we have redundance with ServerB for the OBI Server, but we've lost the web catalog. having the Webcat on a shared local drive on ServerA is a single point of failure.
We are considering creating a small 2 node cluster and having the webcat on a clustered drive resource.
Are there any alternative approaches that others have implemented successfully?
Is there an Oracle option that allows 2 separate web catalogs which are kept in sync through replication?
Thanks in advance for sharing any ideas on this.

Thanks Deepak... do you know anything about replication using sawrepaj utility? Seems a bit difficult to setup, maintain and automate. Lot's of manually setup in config files. Anyone had good/bad experiences using sawrepaj?
(Deepak: tried to give you some "helpful" points, but for some reason, I'm not able to award any points...)

Custom module templates for Web Apps

Just wanting to see if there's anyone out there who knows if the custom module templates from the September release are available for Web Apps? I can't seem to get them to work.
When placing {module_webapps,8168,a template=”/custom/wap-contract.tpl”} I get a "No Items Found" response. I would appreciate help as this would be very useful in building Web Apps and I can't find documentation on it
Thanks

They do work with Web Apps, I've been able to use it successfully. Here is the only documentation I can find on it so far:
http://helpx.adobe.com/business-catalyst/partner/using-custom-templates-modules.html
Curious though, when you get "No items found" that means there are no web app items to show. So we don't really know if your custom template worked or not. If you can get some items to show up and they use the default layout, then we know something is wrong.
Hope this helps,

Problems with "save for web" app low quality messed up images

Please help I have never had a problem with the "save for web" application before (over three years) I am currently running A.I. cs3 on windows vista. in the past whenever I save anything this way the images were always clean. as of yesterday everything I try to save through the save for web app the images are very low quality all the vector has jagged edges, it is very low rez looking and the file sizes are very small, half the size they normaly would be. What did I do to change the settings or better yet how can I get it back to the way it was.

Thank you for your help I moved the folder but it still did not fix this problem. it is also not just the jpg option under the save for web app but all the setting ie. gif, png, ect. ect. Also the the files sizes are much less, example I exported a design as a jpg with the quality setting about 6 the file size was 374kb when I exported the same design through the save for web app the file size was only 45 kb on the quilty setting of 100. further more in the preview screen of "save for web" the original images as well as the optimized both look messed up. The "save for web" app has always worked for me in the past never a problem and I use this app alot so it is very important.

Do we have a built-in option for web based tool in Nexus 5548UP switches for management purpose?

I have purchased Nexus 5548UP switch, i want to know if we have a built-in option for web based tool to manage and configur it just as ASA have ASDM. If there is no such options then what are the options available that can be freely available and can be used to get performance monitoring done.
Message was edited by: Praveen Varun

DCNM (Data Center Network Manager) runs on a server (Windows, RHEL or Solaris) and can be used to manage Nexus devices. It's free for Nexus 1K through 5K devices (paid license required for Nexus 7K management).

There is not a "built-in" management product like ASDM for ASA.

JavaHelp for web app?

     <PARAM NAME = HELPSETNAME VALUE ="GAPIHelp">
</Applet>Also, since applet approach is not that much favored, do you know if any other way to include this tool within web applications or any other tool that would do the same thing?
Any input is greatly appreciated.
Thanks,

Yes, as long as you conform to what the HelpSet specifies you can use Servlets / JSPs.

I'm looking for Failover/High available solutions for IPS 4200 Series

Hi all,
I tried to find out Failover/High available solutions for IPS 4200 series,I didn't saw failover solutions in IPS guide document. Anybody can be help me!

I do not know if this is documented anywhere, but I can tell you what I do. As long as the IPS 4200 has power, with the right software settings, the unit can fail such that it will pass traffic. Should the unit loose power, it does stop all traffic. I run a patch cable in parallel with the in line IPS unit, in the same VLAN, with a higher STP cost. Thus all traffic will traverse the IPS unit when possible, but should something happen to it, a $10 patch cable takes over.

What happened to the add to home page option for web pages. Can't find it.

What happened to the add to home page option for web pages. Can't find it.

Try stopping Safari followed by resetting your phone: double-tap the home button, locate Safari at the bottom (swiping if necessary), tap and hold until it wiggles, tap the minus sign. Now reset: hold the on/off and home buttons until you see the Apple logo (ignore the off slider that appers first), then release. If it still is missing you may need to restore your phone, which will put a fresh copy of the iOS on your phone (see http://support.apple.com/kb/HT1414).

Power Query - How to format options for Web.Content()?

I am trying to access a web api which can return data in either JSON or XML. When connecting with Power Query I get a "400, Bad request" error though and I suspect it could be due to Power Query not explicitly providing accepted Content-Types
in the request. Anyone know how to add options to the Web.Content() request?
http://office.microsoft.com/en-001/excel-help/web-contents-HA104112310.aspx
Thanks!

I believe the default reponse content-type is JSON. It doesn't serve Power Query with anything but an error response though and with the help of Network Monitor I caught a bit more details (in Swedish).
Request:
Http: Request, GET /platsannons/matchning, Query:lanid=1
Command: GET
+ URI: /platsannons/matchning?lanid=1
ProtocolVersion: HTTP/1.1
Accept: */*

Response:

And the API can be found at:

Would be great to be able to define custom headers to the request through options for cases like these. Thanks for the reply!
Best regards,

Modifying Advance CSV export options for Web Intelligence

When we download a Webi report as a CSV(witha dvance options)
In the CSV download advanced options -- We have options for specifying the 'Text Qualifier which is ( " and ' ) and Delimiter (, and ; and tab)
I would like a 'none' option for the 'Text Qualifier' i.e the output columns of the csv should not be enclosed by single or double quotes....
Any suggesstions as to where I can modify this.

1. have you created any hierarchy in the universe ? after creating required hierarchy, in the webi report you need to enable drill mode.
2. you can use opendocument url with sReportName parameter. Please check this doc for details: http://help.sap.com/businessobject/product_guides/boexir3/en/xi3-1_url_reporting_opendocument_en.pdf
But for this you need to export the report to InfoView.

ESP - MQ High Availability options

Hi there,
My organisation (DHS Australia) have recently upgraded our Websphere Message Broker environment from v7 to v8.
As part of this upgrade, in our Production environment we are now running 4 queue managers, the idea behind this is that it helps to provide a higher level of availability (i.e. basically if one queue manager goes down, the others can pick up it’s load).
The ESP MQ adapter currently only allows for connection to the one queue manager, so in our ESP-MQ implementation we are exploring possibilities of how we can possibly get the output from ESP shared across the 4 queue managers. We are looking at a number of options within MQ/Broker itself (eg. clustered queue definitions, clustered queue manager etc), and currently doing some testing to see how/if this works with the supplied ESP MQ adapters.
However, my question for the ESP community/tech-team is whether there has been any thought to implementing something similar to how SAP PI can connect to MQ in a High Availability sense? For example, see this blog post:
http://scn.sap.com/people/anandan.krishnamoorthy/blog/2010/06/08/high-availability-in-jms-adapter
Has there been any thought given to whether the ESP MQ adapter can be enhanced or configured to use a MQ Client Channel Definition Table, as an alternative connection configuration method?
Cheers,
Jason.

Jason - this isn't something that is currently on the ESP roadmap, but perhaps it should be. I'll be interested to see if others in the community have other perspectives on this, or experience doing something similar.

Customizing Print Options for Webi Report

Scenario:
Environment: BO Xi R3.1
Webi report having around 10 tabs in a Single report and all report tabs are built on 1 query.
Requirement
1)Need to have print pop up box which will give the same functionality as Office tools to the end users.
i.e., need a way to bring the Java Report Panel (Edit mode) print dialog box to the DHTML (View Mode) so that End Users have more options for printing.
2)Need to have an option to print report tab selectively.
3)Need to have an option to print reports for multiple filter selections.
Any pointers, suggestions to the above requirement are of great help.
Appreciate, if the Specific SDK class details are also mentioned with any possible options.
Thanks in advance
Vijay B

Lawrence,
The form is where I concatenate the SQL that is the record source of both the report and the subsequent record updates. So the form is always open before the report is opened (that is where the code to open the report resides and is run), and it must remain
open while the report is open to maintain the value of the variables, including the WHERE clause of the SQL statement that will be used for the posting process when the user closes the report. That is, the SQL used to open the report MUST match the
SQL used when posting the records, or the user could change some selection parameter and post records not on the report.
And I open both the form and report modally to prevent a user from inadvertently running the report's Close event outside the context of the form, with its variables all set for the posting process.
I know I could pass all of this to public variables, but I am trying to keep it as clean and as close to the Form -> Report -> back to Form as I can.
