What is a good design for remote Views?

Hi All,
I am thinking how would I design my process for performance consideration in retrieving dynamic values of table/view data.
The requirement is like this:
1. We have 50 databases residing on each own server counterpart (50 servers).
2. Each database has table Patch_LeveL (apps_name, patch_level), which contains just one row only to reflect the latest patch level applied for the apps on this database. Note that are we constantly on applying service packs for this apps.
3. On our central monitoring server (db). I create 50 database LINKS for each of the 50 databases.
4. I created 50 views over these links to make it centralized to represent the 50 Patch_Level tables. As patch_level_view1, 2, 3.....patch_level_view50.
5. I then create a central view as .... as union of the 50 individual views Actually I am just planning to do the above activity.
My question is....is this a good design for performance? Can you share be a better approach?
Is there a limitation of joining "union" of 50 views?
Thanks a lot,

Is there a limitation of joining "union" of 50 views?What can happen is if the connection to one of these servers is interrupted, the big "union" view will not work. As said by above poster MV, with lets say an hourly refresh, helps with this situation as you have the data that was gathered last time (and most likely it is still valid).

Help networking a Security System DVR for remote viewing

Hey,
I am trying to network my Security System DVR for remote viewing but cannot seem to get it working. I have read some post on this site as well as many others and followed instructions to the T but to no avail.
Here's what I've got:
Linksys WRT54G2 V1 connected to a modem.
My DVR has 3 settings for networking:
-PPPOE
-Static
-DHCP
On DHCP, The DVR automatically sets these settings:
IP Address: 192.168.1.100
Subnet: 255.255.255.0
Gateway: 192.168.1.1
and then the DNS is the same as the one on the "status" area of the router settings...
Port: 10000-10020
I set up port forwarding for 192.168.1.100 for port 10000-10020 selecting "both"
If I pull up the "DHCP Clients Table" it shows the above IP Address but with no name....and the MAC address is something like ee:ee:ee:d4:03:5f.
I have tried to change the DVR to Static and do everything manually but thats not working either.
I created a Dynamic DNS with goddns.org but the DVR seems to have its own one built in that you cannot change. (at the bottom of the network settings it says something like "URL: 123484984.goddns.org----Status: OK." But when I try to type that in the address bar of IE it goes no where.)
I hope someone can tell me why its not working.... It was working when we first got everything set up...then it stopped. then I messed with it and got it working but didn't know what I did. Now its broken again and I don't know what to do.
-Ian
PS. When I am connected to the router via LAN cable and I type the internal IP Address assigned to the DVR by the DHCP (192.168.1.100:10000) it brings up the DVR menu perfectly. But when I try to log into it from a different location...with the external IP address...thats when I have trouble. I do not think my external IP has changed since I got this router set up.
Any help would be awesome.

Hmmm... Did that and I can't seem to get it working still. Whats weird is that as long as I am connected to the router...I can access it through the internal IP address.... (if using DHCP its 192.168.1.100:10000 and if using static its 192.168.1.99:10000)
Those both work when set up on DHCP for the first and Static for the second. But as soon as I type the external IP address with the port it doesn't work. Its like there is a firewall OR the port forwarding is not working. But everything on the port forwarding page looks good... Its enabled, set on Both, correct port range... 10000-10020...
Any Ideas?

What's a good book for getting started?

I've been doing web design in HTML and ColdFusion for almost 3 years. It's clear that ColdFusion is on it's way out and I need to learn J2EE/Java/JSP etc. I have a few questions:
Java is a term I've heard associated with C++ and other types of programming as well as Web design. Are the Java/C++ Java and the Web Java basically the same type of language? Is the Web Java and JavaScript the same thing? I'm very confused!
What is a good book for getting these types of questions answered and getting started in J2EE/Java/JSP? There are quite a few variations of script languages out there and I want to make sure I learn the right stuff, ie the stuff that employers are going to be needing.
Thanks!

Here is a free online version of a good book:
http://pdf.coreservlets.com/Core-Servlets-and-JSP.pdf
Print it off or read from the screen. Otherwise, there are several good Java books out there. What I would do is go to the bookstore and thumb through a few books. Depending on what type of book you want (example based or theory) find the books that you think would satisfy your learning style. Write down the names and authors, go home and buy them used online at Amazon for tremendous discounts. This way you can buy several versus just one.

What is a good strategy for keeping the OEM GRID up and running?

Hi,
What is a good strategy for keeping OEM GRID up and running? Currently, we have grid installed on one linux64bit box with 4 cpus and 8 gigs of RAM, oms 10204, repdb 10204, agent 10204. In addition to using this oem grid for notifications and performance monitring, we are also using this oem grid for scheduling over 700 jobs running over 30 targets.
What is a good strategy to have to backup the grid so that when this box goes down, we can restore and then recover the grid? Please lead to white papers or documentations. Thank you.

What is the Different Types and Usage of Views
The followings are different types of views:
- Database View (SE11)
Database views are implement an inner join, that is, only records of the primary table (selected via the join operation) for which the corresponding records of the secondary tables also exist are fetched. Inconsistencies between primary and secondary table could, therefore, lead to a reduced selection set.
In database views, the join conditions can be formulated using equality relationships between any base fields. In the other types of view, they must be taken from existing foreign keys. That is, tables can only be collected in a maintenance or help view if they are linked to one another via foreign keys.
- Help View ( SE54)
Help views are used to output additional information when the online help system is called.
When the F4 button is pressed for a screen field, a check is first made on whether a matchcode is defined for this field. If this is not the case, the help view is displayed in which the check table of the field is the primary table. Thus, for each table no more than one help view can be created, that is, a table can only be primary table in at most one help view.
- Projection View (SE11)
Projection views are used to suppress or mask certain fields in a table (projection), thus minimizing the number of interfaces. This means that only the data that is actually required is exchanged when the database is accessed.
A projection view can draw upon only one table. Selection conditions cannot be specified for projection views.
- Maintenance View ( SE54 )
Maintenance views enable a business-oriented approach to looking at data, while at the same time, making it possible to maintain the data involved. Data from several tables can be summarized in a maintenance view and maintained collectively via this view. That is, the data is entered via the view and then distributed to the underlying tables by the system.

What are the browser recommendations for best viewing iWeb 08 site on a PC?

What are the browser recommendations for best viewing iWeb sites on a PC? Can't find any info on Apple iWeb site.

Hi,
I don't think there are recommendations from Apple.
What I can say is that the newest version of InternetExplorer at the UniversityCampus is working great with my website I didn't find any problem (Menus, Slideshows, text displaying, pictures everything worked great). There are IE problems reported in other threads but I think they refer to older IE versions (seems like most IE users still have older versions on their PCs).
Newest Firefox will work too.

What's the best APP for remote desktop viewing?

There are so many ... !
Also, what's the best app for file sharing between ipad and computer? Thanks!

Yeah, I guess doing extensive editing with DTG isn't much fun. The only way to get it from DTG to Pages is to email the file from DTG to yourself. DTG lets you email any of its files. Then from the iPad's email, open the file in Pages (when you open the document there will be an "Open in Pages" button on the top right). However, the only way to get it back into DTG is to again email the Pages file back to yourself (as a Word file), open it from your computer, replace the old file with this one and then resync with DTG.
There's also a bug in DTG's reader which tends to cut off one side of the doc when you scroll thru it. Hopefully DTG will have an update soon. They say it's coming on their app page. I think you'll be much happier with it when that happens.
Go to App Support from the App page of FileBrowser in the App Store. There on the right of the opening web page you'll see setup instructions for the Mac and Windows XP (the Windows XP instructions work pretty much the same way for everything up to and including Windows 7). That should get you up and running with FileBrowser. It's really pretty easy once you know what to put in those blanks.
Sorry you're not happy with these. Hope they get to be a better experience for you. Feel free to email me with any questions you may have.

What is a good extenstion for pop up menus?

I recently created a site in Fireworks that used pop up menus
but then found out later that they don't work on Internet Explorer
(you can view the site at www.caspre.com it is the very last menu
item at the end called "about cascade"). What I need to know is if
there is a good extension for dreamweaver (or fireworks) that won't
cause problems in ie. It should be noted that the pop up menu works
great in Firefox.

AVMS - No Network settings to allow for remote viewing

Hi,
I've setup a new PC with the latest AVMS to test the app versus the old one. I setup the server component and it runs fine but when I try to access it remotely via the client app, I cannot contact the server.
Checking the in documentation it says to go into the Main Console, and in the setup menu select Network Server to enable it. The problem is mine is greyed out.
I am just using the basic license for less than 16 cameras.
Did I miss something on install?
Thanks in advance,
Bob James

I think I figured it out; I activated the Basic license, you need Basic Plus or Advanced to have these features.
So I put it back to activating the trial and I get the network connection. I tested and Remote viewer works.
Looking at pricing I almost fell off my chair; $1100 for Basic Plus licensing?!
I mean I want to see the viewer from another computer, but for that much I'll just RDP into the box and watch the real viewer....
Wow, what's up with the prices...

Right for Remote View Only?

I am using ZfD3.2sp2 with ConsoleOne 1.3.5 or 1.3.6. I have a Help
Desk
that I would like to grant Remote View of a group of workstations. I
am
able to remotely control workstations as administrator. I have
checked
Remote Operator tab and the users show with Remote View and I have
granted
read right to the WM:Network Address property and write to the DM:ZEN
Remote View property of the Workstation object. I am able to ping the
workstation but receive a failure due to rights issue.
Can anyone tell me what rights I really need to allow a non-admin the
ability to RC a workstation?
Thanks,
Rob Bennett

Rob,
How about this one?

Minimum rights for remote view/control

I am in the process of cleaning up rights in my eDirectory because our last Novell admin was quit liberal with assigning rights. What I need to know is what are the minimum rights needed to remote view a workstation and what the minimum rights needed to remote control a workstation. I have been searching Google and the forums for a while with no luck.

Thanks for the quick response.
I ran through the wizard and then looked at rights it gave the account. It looks like the attributes are as follows:
Remote Control:
DM:Remote Control -- write
WM:Network Address -- read
Remote View:
DM:ZEN Remote View -- write
WM:Network Address -- read
The only thing I wanted to verify was, do I need to give those rights to the user objects as well as the workstation objects in order for this to work? I know some of the techs use C1 and right-click on the user, then select 'Remote Management'. Just not sure if I need to give rights to the user objects as well since the user will be logged in at the time the tech will be remote controlling/viewing.

What is the best practice for changing view states?

I have a component with two Pie Charts that display
percentages at two specific dates (think start and end values).
But, I have three views: Start Value only, End Value only, or show
Both. I am using a ToggleButtonBar to control the display. What is
the best practice for changing this kind of view state? Right now
(since this code was inherited), the view states are changed in an
ActionScript function which sets the visible and includeInLayout
properties on each Pie Chart based on the selectedIndex of the
ToggleButtonBar, but, this just doesn't seem like the best way to
do this - not very dynamic. I'd like to be able to change the state
based on the name of the selectedItem, in case the order of the
ToggleButtons changes, and since I am storing the name of the
selectedItem for future reference.
Would using States be better? If so, what would be the best
way to implement this?
Thanks.

I would stick with non-states, as I have always heard that
states are more for smaller components that need to change under
certain conditions, like a login screen that changes if the user
needs to register.
That said, if the UI of what you are dealing with is not
overly complex, and if it will not become overly complex, maybe
states is the way to go.
Looking at your code, I don't think you'll save much in terms
of lines of code.

Analog to Digital Converter-- What's A Good Product For My System?

What would be a good analog to digital converter for Final Cut Express HD 3.5 on a Mac OSX 10.4 system? I've used a Canopus on a MacPro with Final Cut Pro before and liked it, but wasn't sure what would be a good product for my macbook. I've looked at the Canopus advc-110 and 55 but am not clear on the difference and if it would work with what I have.

The ADVC-55 is capture only. It includes composite & s-video inputs and stereo audio inputs. Firewire output.
The ADVC-110 is bidirectional (meaning you can both capture and output through it - this is a very good way to monitor your video during production as you can see the actual quality on a monitor/TV rather than just your computer screen, which has limited capability to show you the actual video quality.) It includes composite & s-video inputs and outputs; stereo audio inputs & outputs; Firewire input & output.
The ADVC-300 is also bidirectional and includes composite, s-video and component video i/o (D1 connector) inputs & outputs; stereo audio inputs & outputs; Firewire input & output; and software that enables you to tweak its video settings. Helpful in cleaning up particularly bad analog videos.
I've used these things for years and they all work great. I do not believe there is any difference in the internal conversion hardware ... The primary differences are support for one-way vs. bidirectional conversion; input/output connectors; and the software that comes with the ADVC-300.
If you have basically clean analog video, any of these units will be fine. You can use any analog source (VHS deck, camcorder, DVD player, etc.) and would typically use iMovie or Final Cut Express to capture your video on a Mac.
