What is database /DBMS "patch access"? - database

Could not find this term very easily on google.
I assume it's the ability to patch a DBMS with an update without stopping service.
Is this correct? If not, please guide me.
Thanks in advance.

Patch Access usually refers to a service to (preferrable easily) get access to relevant patches (for your dbms in this case).

When is the getSchema function called?

Does anyone know when the getSchema function is called, or what calls it?
For that matter does anyone know of any documentation that outlines the flow between the Google Data Studio Connector functions.
So I think I can answer my own question, but if anyone can add any clarification that would still be welcome.
It appears that this function provides the full list of connector fields, specifically when the connector is connected to a data source.
It may be called at other points as well which where some further clarification would be useful.
getSchema() is called by Data Studio when Data Studio needs to know the schema. This usually happens 1) right after you complete the configuration for a community connector or 2) when you are editing a data source in Data Studio and reconnect to it.

what is the best way to debug vCloud client REST applications?

I'm building a vClould client application via the REST APIs, however, the documentation is inconsistent an in some cases just wrong and misleading.
All I really need is a solid debug tool or even a log file. Any recommendations?
You already mentioned you have access to the message stream, which is one of the first steps. Typically if I'm using the Apache HttpClient/HttpComponents I'll go increase the log level so it logs the full HTTP requests.
My next step is usually to cheat and to log into vCD as a system administrator and see what's going on. When vCD was designed there was a very deliberate decision to not reveal infrastructure level problems to tenants of the cloud (normal org users or org admins), as that would break the cloud abstraction. Sadly, that means as an org-level user you're often going to get "contact your cloud admin" error responses. We are aware that this isn't ideal and try to find ways to make it better when we can (IIRC the new 5.5 release that was announced last month does have some improvements in that area).
The last step is usually to cheat even more and to look at the server side logs (vcloud-container-debug.log, specifically). That usually gives me a better clue as to what went wrong. Of course, you may be unlucky and not have access to the vCD cell machine.
My workaround in the latter two cases is to try the operations via the vCD UI and see (1) if they work as expected and (2) if they do, to check the system state via the API and see if I'm sending the wrong request payloads, etc. because the doc or schema reference may not have been clear enough.
In regards to the documentation, please use the feedback links () found on individual doc pages to let us know! Our technical writer reviews all the feedback and tries to address them.
My final suggestion is that you might want to post API questions to the vCloud API community forum VMware has. There are a number of experts (both users and VMware employees) that monitor it and respond to questions.

Drupal 7, Domain Access, and SSO (Single Sign-On)

Has anyone made any headway with coming up with a single sign on solution
with Domain access to date for Drupal 7? I've been looking closely at two old
modules, one no longer maintained (SSO for D6) and one still maintained (CAS). I've also read that SAML might be a key to unlocking this, but am uncertain.
Facebook's FBConnect might be another option too or another way could be integrating OpenID from what I've read, and experienced on StackOverflow's sub sites.
I know that OpenID can do this since we are logged into all of *Overflows sub sites at the same time using one login. The question is how does it cross DNS servers? Does it handshake with one half of a matching hash? I cannot find any documentation on this, so am at a loss.
So, are there any solutions that are known to date, or information on what to start
looking into? I think I've made a good point at the possibilities. I read this thread, Domain Access SSO but am uncertain to what version it pertains to (Drupal. DA, SSO or otherwise). It looks like the "Solution" is to create a master table set with users and permissions, then share those across the domains? How might this work if there are already multiple sites created under Domain Access? Would you clone and rebuild the entire installation, or would you need to start from scratch? It really raises more questions than answers. I contacted the author with no response, so the questions still stand.
Any opinions out there on the who what or why would be greatly appreciated, I just need a start point to get the ball rolling. Thanks everyone.
I'm the author of the Domain Access SSO article mentioned in the original question. I don't recall being contacted about it, but then again I recently learned that my "contact" page on bleen.net hasn't been working in a while... but anyway, here is a bit of info:
That post referred to Drupal 6, SSO Module 6.x-1.0-rc1, and Domain Access module 6.x-2.0 (I think). That solution basically revolves around creating two separate drupal installs, one the master and one the client (there can be multiple clients). Basically, what happens is the necessary user tables for all teh clients are pointed instead to the master. In doing so, the master becomes (essentially) a shell site that does nothing but hold and verify user data.
Hope that makes sense and/or helps... to be honest i havent looked at that code in a long while now.
SAML is a good option. Check this module to integrate it with drupal:

If you need a demo with this plugin working check this.

Preventing dictionary user names for registration

When I was setting up an account with gmail few years back (probably this is still a case, haven't check) I've noticed that system doesn't allow to register common terms, nouns as username, it seemed that it used a sort of dictionary for screening. I would like to implement similar feature in my app, anyone have idea how to tackle this? App is written in PHP but understand I'll have to hook it up with online service.
Thanks
Wordpress MU has such feature too, you fill a list of possible usernames that you want to avoid and they become unavailable for users. You can check its source to get their approach...
Sinan.
Well the API will vary from service to service so I'd suggest you find one, look at their developer docs and then if you have a question ask it here.

Best Way to automatically find links to your content?

So, here is the task I've found myself thinking of. Pretend for a moment, that I have a large body of content. I want to see what websites are linking to my content. I know that I could look into TrackBack or PingBack but what about those that aren't using tools capable of dealing with that?
It would seem that some form of Web Crawler that looks for pages linking to the original document might be useful. My question to the greater community is what would be the best way to get started here? Do TrackBack and PingBack do more than I assume? Are there services or tools out there that already do what I'm thinking?
Google is your friend!
Use the link prefix:
link:whatsite.com
And yes, trackbacks do more.
If you have HTTP referers setup in your logs, you can mine them.
You can even discover pages taht does not know about.
Else, there is the paying Linkscape from Seomoz or the free majesticSEO (if you confirm ownership of the domain).
MajesticSEO has a bigger backlink index and an API (need to login!).
