Number of Datafiles and best pactice for datafile

Is there a recommended number of data files that should be created with each Oracle database installation? Or best practice?..
What is the typical number? What are the pros and cons of having a large number of data files vs a smaller number?
we have created >3000 data files for 1 database. This is based on Customer's request. I want find out if this is against current industry best practice..

Hi,
imho it depends on your architecture as well...if you put all the data for all your tablespaces in one file and customers create heavy traffic on various tablespaces you could be in for a gain in performance if you split the tablespaces on several files on different disks.
After all is said an drunk, the customer is King. If he wants a gazillion files, you have to provide for him. The customers usually buy their application off some company to whom they pay huge maintenance bills (the rule sometimes seems to be: if it's expensive, it's got to be good). And those companies are sometimes hard to seduce to change their proven concept/architeture. Nevertheless, as Satish Kandi said: for you manageability should come first; so get yourselves a good set of nerves on a nice day and go for the discussion. Remember: The DBA Knows Best! ;-)

Can anyone recommend tips and best practices for FrameMaker-to-RoboHelp migration ?

Hi. I'm planning a migration from FM (unstructured) to RH. I'd appreciate any tips and best practices for the migration process. (Note that at the moment I plan to import the FM documents into, not link to them from, RH.)
For example, my current FM files are presently not optimally "chunked", so that autoconverting FM file sections (based on, say, Header 1 paragraph layout) won't always result in an optimal topic set. I'm thinking of going through the FM docs and inserting dummy paragraphs with a tag somethike like "topic_break", placed in more appropriate locations that the existing headers. Then, during import to RH, I'd use the topic_break paragraph to demark the topics. Is this a good technique? Beyond paragraph-based import delineation, do you know of any guidelines for redrafting FM chapter file content into RH topics?
Also, are there any considerations/gotchas in the areas of text review workflow, multiple authoring, etc. after the migration? (I've not managed an ongoing RH doc project before, so any advice would be greatly appreciated.
Thanks in advance!
-Kurt
BTW, the main reason for the migration: Info is presently scattered in various (and way to many) PDF files. There's no global index. I'd like to make a RoboHelp HTML interface (probably WebHelp layout) so it can be a one-stop documentation shop for users.

Jeff
Fm may produce better output for your requirements but for many what Rh produces works just fine. My recent finding re Word converting images to JPG before import will mean a better experience for many.
Once Rh is set up, and it's not difficult, for many its printed documents will do the job. I would say try it and then judge.

Hi,
Sorry, we do not support a matrix-question field. Please try the multilines text field (where your participant can enter multiple lines in the input text box) and see if it works for you.

Powershell script to find number of major and minor version for a item

Is there a way to figure out to get the total major and minor version count for an item in powershell.
I can get the count on basis of following
“Item Versions” = $item.Versions.Count
but not sure how to get number of major and number of minor version for an item. Pls advice.
Thanks Basva

Hi Basva,
There might be an easier way, but this should work:
foreach($item in $list.Items)
$minor = 0
$major = 0
foreach($version in $item.Versions)
if($version.Level -eq "Draft")
$minor += 1
else #Assume Level must be Published
$major += 1
#The variables $minor and $major will now hold
#the correct number of versions for this item

Best Pactice for Connecting ASA to Catalyst Switch with Mulitple VLANs

Hi all,
Have the following network topology that was in place when I started the job (See attached pdf). Am thinking it might be better if I could eliminate the Cisco 2811 router and connect directly from the ASA to my 12 port fiber switch (192.168.7.1). In my thinking this would eliminate an unnecessary piece of equipment and also give me a gig link to my ASA as opposed to the 100 meg link I have now with the old router. The 12 port fiber has links to most of my IDFs and is acting as my VLAN gateway for all inter VLAN routing.
Is my current topology ideal or would I be better served to remove router and connect directly to the 3750G-12s Fiber switch or my Master Switch (192.168.7.4)? Only thing I don’t like about direct connect to Master switch is that it takes scheduling a major outage for me to reboot it. However, if that is best practice in this case, I can live with it.
It appears the 12 port fiber cannot have IP addresses assigned directly to Ports, only to VLANs. So would I have to create a separate vlan for my ASA and assign IPs to the vlan on each end of the connection?
I have read some suggestions that say it is better to terminate all VLANs on the ASA. So as I understand that would require creating subinterfaces on my ASA LAN port and assigning each subinterface to its own VLAN Inter VLAN routing would then be controlled by ASA.
Does not seem practical to me as I have about 15 VLANs total. Not showing everything in the drawing.
Guess my main question is “What is best practice for topology and routing in my scenario?”

Hi Mcreilly,
You should be able to assign an ip address on cat6k sup720 if you are running native ios on sup 720.
If you are running catos then you will not be able to do that and you can have it configured as trunk and connect to the router.Also I do not think that you need subinterfaces on router and trunk on switch because your cat6k with sup720 must be doing intervlan routing between vlans.
You can just connect it on some port on any vlan and same subnet ip address which you have it on msfc for that vlan you can assign on the router interface and anybody want to go out via t3 link will get routes on sup720 and move out via router vlan.
For suppose you do not want the router to be part of existing vlan you can create one vlan on cat6k sup720 and assign one port to that new vlan and connect the royter to that new vlan port and then create logical interface on msfc for that new vlan and assign an ip address range on that logical vlan and same subnet ip address range you can assign on router physical interface.
Any one from other vclan get routed on sup 720 msfc and will move out via the vlan on which you have connected the router.
because you have only one router you will not be able to maintain box level redundancy by which i mean if the router goes down t3 will be unreachable.

Tips and best practices for translating C into LabVIEW? SERIOUS newbie...

I need to translate a C function into LabVIEW. This will be my *first* LabVIEW project. I've been reading some tutorials, and I'm still struggling to get my brain out of "C/C++ mode" and learn the LabVIEW paradigms.
Structurally, the function that I need to translate gets called from a while-loop and performs a bunch of mathematical calculations.
The basic layout is something like this (this obviously isn't the actual code, it just illustrates the general flow control and techniques that it uses).
struct Params
// About 20 int and float parameters
int CalculateMetrics(Params *pParams,
float input1, float input2 [etc])
int errorCode = 0;
float metric1;
float metric2;
float metric3;
// Do some math like:
metric1 = input1 * (pParams->someParam - 5);
metric2 = metric1 + (input2 / pParams->someOtherParam);
// Tons more simple math
// A couple for-loops
if (metric1 < metric2)
// manipulate metric1 somehow
else
// set some kind of error code
errorCode = ...;
if (!errorCode)
metric3 = metric1 + pow(metric2, 3);
// More math...
// etc...
// update some external global metrics variables
return errorCode;
I'm still too green to understand whether or not a function like this can translate cleanly from C to LabVIEW, or whether the LabVIEW version will have significant structural differences.
Are there any general tips or "best practices" for this kind of task?
Here are some more specific questions:
Most of the LabVIEW examples that I've seen (at least at the beginner level) seem to heavily rely on using the front panel controls to provide inputs to functions. How do I build a VI where the input arguments(input1, input2, etc) come as numbers, and aren't tied to dials or buttons on the front panel?
The structure of the C function seems to rely heavily on the use of stack variables like metric1 and metric2 in order to perform calculations. It seems like creating temporary "stack" variables in LabVIEW is possible, but frowned upon. Is it possible to keep this general structure in the LabVIEW VI without making the code a mess?
Thanks guys!

There's already a couple of good answers, but to add to #1:
You're clearly looking for a typical C-function. Any VI that doesn't require front panel opening (user interaction) can be such a function.
If the front panel is never opened the controls are merely used to send data to the VI, much like (identical to) the declaration of a C-function. The indicators can/will be return values.
Which controls and indicators are used to sending data in and out of a VI is almost too easy; Click the icon of the front panel (top right) and show connector, click which control/indicator goes where. Done. That's your functions declaration.
Basically one function is one VI, although you might want to split it even further, dont create 3k*3k pixel diagrams.
Depending on the amount of calculations done in your If-Thens they might be sub vi's of their own.

UI Defaults Import problems and best practice for using UI defaults

Hi,
I'm hoping some of you experts can tell me how to Import the UI Defaults from Schema A and Workspace A to Schema B and Workspace B. My goal is to fluidly share the UI defaults with another developer as we march forward creating new versions of the application (inside new Workspaces with new schema names). My longer term goal was to create a "library" of UI defaults that other future developers could easily access as well.
The basic setup I have been using is that each developer gets their own schema and their own workspace. When a new version of the database design is made, I keep the older versions of the workspaces and schemas intact and then create a new workspace and new schema for each developer (just two of us right now). Then we Export apps, respectively, from our old workspaces and Import apps into our new workspaces. I also create a new db tablespace and new db user account and map to new workspace as well. This way I always know what db design version we are using against what Apex app version and can, conversely, delete tablespaces, user accounts, workspaces and Apex schemas in one swallow without worrying about getting the wrong version of something accidentally deleted. 9It may seem like I am doing a lot of extra work, but my sanity is still (relatively) intact.)
I keep getting
"ORA-20001: GET_BLOCK Error. ORA-20001: Execution of the statement was unsuccessful. ORA-20001: You do not have access to the schema that you are importing. Import failed. <pre>begin wwv_flow_api.g_id_offset := 0; wwv_flow_hint.g_schema := 'MY_OTHER_SCHEMA'; wwv_flow_hint.check_schema_privs; end;</pre>"
when I try importing it.
We want to share our UI defaults that we each set up in our respective workspaces and schemas. We do have some overlap of tables (which may be a no no I suppose). We also each have differently named (test) apps.
So, like app Import/Export, I thought I could just Export my app (along with UI) from Schema A and Workspace A and simply import it into Schema B and Workspace B and then in the new Workspace have access to the UI. I tried editing the UI *.SQL using the app ID and new schema name but it still balks. It seems like there is an internal table ID code specific to each table that is particular to the table and the workspace it was created in.
I can go to a specific workspace, create a sample UI, Export it's app, and Import the same app (new ID) into same workspace and the UI shows up fine.
So, what good is the UI defaults if you can't carry them forward to the next version of your app that is in a new workspace? It seems like we are forced into creating the equivalent of one workspace, say the "Library", and both of us with separate schemas sign into here. But then how do I get the UIs from the "Library" to our "Beta" workspace, and similarly from there to 'Production' without recreating UIs each time? And, if I prefer a sample set of records, say only 100 test recs, and the other developer prefers a full set, say 30,000 recs, and we have to use the same workspace, since the workspace can only be associated with one db tablespace, how can I load both 100 and 30,000 recs into same area? (and since we can't, that is another reason we wanted to use separate workspaces and pass our respective UIs back and forth and finally into the shared "Library" area.)
Well, thank for reading through this and hopefully it makes sense.

OK Scott, let me try to clarify here:
Regardless of what reasons I have, my immediate goal is to sucessfully Export the UI Defaults from Schema A and Workspace A and Import into Schema B and Workspace B.
So, logging in as Schema A into Workspace A, I go to my app, then Export/Import then "Export User Interface Defaults". There is only one schema available to choose from in the "Schema" dropdown select list. I export the UI and save it to a file.
Next I logout and then login as Schema B into Workspace B. I go to Shared Components UI Defaults and display my tables. Most of these tables (about 30 of them) have the same exact name as the tables used by the other schema. UI Defaults do not exist.
I choose "Import" in the Tasks list, File Type "User Interface Defaults" and pick file I just exported. File is successfully Imported. Now I'm on screen for installing the UI Defaults. When I try to Import the UI it brings me to "Confirm Replace UI Defaults" and lists the OLD workspace schema (not the new one I expected)as being removed and replaced. I push ahead, tell it to do the replace and get the "You do not have access to the schema that you are importing". So I guess I'm doing something wrong.

How do I prepare my iMac for sale? And best practice for transferring media to a new system.

This is my first time posting in a forum, so I will apologize in advance if I'm doing something wrong. I've tried to search for a very clear answer to my questions in the existing discussions, but have not had much luck.
I ordered a Macbook Pro today and would like to sell my current iMac to supplement some of the cost. I purchased my iMac in March of 2011 with OS X Snow Leopard preinstalled. I've since updated to Mountain Lion. When my computer came in it did not have OS DVDs, so I am not sure exactly how to take it back to factory default and remove ALL of my information safely in order to prepare it for sale. I'm afraid to tell it to format if I am going to need a boot disc/drive to reinstall the OS. I've been trying to research all day and have learned that I will not be able to sell it with the current OS, only the one that came with the computer at the time of purchase (to the best of my understanding).
Secondary to all of this, I have a question about backing up info and porting it to my new system. I have run the Time Machine backup to my external hard drive. However, I DO NOT want to port it to my new MBP as an image of my past machine. I did that when I got my iMac from my old MBP and my iMac thinks it is a MBP (MBP EFI/SMC Firmware Update Icons in my system utilities folder as well as identified as a Macbook Pro on my network). I've never been able to get all of these things to go away and I feel like it's chewing up hard drive space for no purpose whatsoever. I also worry that it could create system issues that I'm just not savy enough to catch before they are beyond control. That being said, I'd like to begin fresh with my new MBP. What is the best method of bringing my photos from iPhoto and music/movies/books/etc from iTunes to my new system? My word documents are easy enough...I keep 3 flash drives updated with them at all times.
Thanks in advance!

Whoever said you can't sell you iMac with the current Mac OS X is wrong, I believe.
Unfortunately, it is not wrong.
Any OS purchased/obtained at the app store - as is the case here - is not transferable. The license is tied forever to the Apple ID used to obtain it. The SLA states that the seller needs to erase the drive and reinstall the original system.
@ Kamikazwe:
You can call Apple and give them your serial number and they will send you copies of your original disks at a nominal charge.
You do need to use your original Snow Leopard disk, boot from it, erase the drive, and reinstall Snow Leopard. The buyer of the machine will need to purchase his/her own copy of Lion or Mountain Lion with their own Apple ID or they will never be able to reinstall or update the OS.
SLA Excerpt:
3. Transfer.
A. If you obtained the Apple Software preinstalled on Apple-branded hardware, you may make a one-time permanent transfer of all of your license rights to the Apple Software (in its original form as provided by Apple) to another party, provided that: the Apple Software is transferred
together with your Apple-branded hardware; (ii) the transfer must include all of the Apple Software, including all its component parts, printed materials and this License; (iii) you do not retain any copies of the Apple Software, full or partial, including copies stored on a computer or
other storage device; and (iv) the party receiving the Apple Software accepts the terms andcconditions of this License. For purposes of this License, if Apple provides an update (e.g., version 10.8 to 10.8.1) to the Apple Software, the update is considered part of the Apple
Software and may not be transferred separately from the pre-update version of the Apple Software.
B. If you obtained your license to the Apple Software from the Mac App Store, it is not transferable. If you sell your Apple-branded hardware to a third party, you must remove the Apple Software from the Apple-branded hardware before doing so, and you may restore your system to the version of the Apple operating system software that originally came with your Apple hardware (the “Original Apple OS”) and permanently transfer the Original Apple OS together with your Apple hardware, provided that: the transfer must include all of the Original
Apple OS, including all its component parts, printed materials and its license; (ii) you do not retain any copies of the Original Apple OS, full or partial, including copies stored on a computer or other storage device; and (iii) the party receiving the Original Apple OS reads and agrees to
accept the terms and conditions of the Original Apple OS license.

Best Practices - How to adjust light in selected areas and best options for export (only adjust ligh

Hello,
I have the cs suite, and recently downloaded the lightroom demo. I am fairly good with picking up programs but couldn't locate where or how i can select individual elements to lighten/darken? If i wanted to make a an object lighter, should i be doing this within ps or is there an easy to use tool within lightroom?
Second question, when exporting into ps, what is the best practice.. should i only adjust lighting and any other edits within ps?
cheers
Kenny from Vancouver

Take a look at the Adjustment Brush. It's in the tool pallette, just below the histogram when you're in the Develop Module. It will not only dodge and burn, but allow you to apply lots of other kinds of local changes.
In general, I find that I can do everything in Lightroom for most images.

Hi Sunny,
                Thanks very much for your response.
The major problem that i am having is I some how did not include the BBPCRM software component or the related software components for CRM at the time of upgrade is my best guess.
So, the latest add ons BP-CRM60 600V3 and BP-CRM70 700V1 or the add ons BP-ERP05 600VD/ 603V7 along with that BP-INSTASS 600V7 are not able to install because the prerequisite are not meeting. Only BP-INSTASS 600V1 got installed.
Can any one tell me how and what to do now.... plzzz???
Things like how to get the CRM related s/w components installed or if there is a work around to get the Baseline Packages (IN) activated with out the CRM.
Regards,
Antony Chaitanya.

What is the Best Hard Drive for a Powerbook Pismo 200 and best size for sto

I have a Power book G3 Pismo 2000 which came with a 10 GB Hard Drive. It is almost full and I want to upgrade the Hard drive to a bigger and I do not know the best hard drive and what is the maximum space I will need? Can you recommend size and Manufacture?

I bought a 80GB Toshiba for my Pismo. It seems to work well. I believe the largest drive that will be fully recognized is a 120GB drive.
Here's a good place to see your options. Go to this web page at OWC and get a listing of your upgrade options for your Mac model.

Scheduling wake up from sleep - how-to? and best time for cron and backup?

Background (or you can skip straight to question below): We use Retrospect to backup a number of machines over a network. We usually log the machines off and let the screens go to sleep however I'd prefer to log them out and then let the whole machine go to sleep and have them wake up for cron maintenance and backup.
One problem is I can't get Retrospect to wake the machines up, even if I have "Wake up for Ethernet network adminstrator access" checked in the Energy Saver Preference Pane, so I've scheduled the machines (under the Energy Saver Preference Pane) to "Start up or wake up" Every Day just before the backup starts (11:30 pm). (Note: the "Weekdays" option doesn't seem to work under 10.4.3).
So here's my question: what's a better time to have them wake up with regard to cron maintenance (considering they're currently set to go to sleep after 1 1/2 hours, which I'd rather make 1/2 an hour), and does it make any difference if I run the backup before, during or after cron maintenance?

Hello again Christiaan,
IMO, do not take this nightly automatic maintenance into account as it should not, and does not, influence your work and habits.
--> Since 10.4.2 the nightly tasks run automatically anyway (delayed), even if your computer was asleep at the default scheduled times. A very good enhancement, that would be perfect if only we could leave our computers ALWAYS on without restarting ever.
Still no automation if shut down at night neither.
Your question:
In Panther the answer is simple: Wake up at 3:10AM and back to sleep at 5:40AM (because the default maintenance times are 3:15am every day (daily task), 4:30am on Saturdays (weekly task), and 5:30am on the first day of each month (monthly task)).
In Tiger, the default times are the same (except the weekly task at 3:15 instead of 4:30), but they get delayed by the amount of time you slept your computer since the last reboot,
so,
--> you can never know when the maintenance will run, unless your computer NEVER sleeps.
Not a problem, because it is designed to run in the background, while your computer works (with Retrospect for example).
Just run this maintenance yourself manually once a month to make sure it's done. Once or twice a month is enough.
Use one of the "cache-cleaning" utilities or paste this command in Terminal:
sudo periodic daily weekly monthly
Post back if you have more questions.
Good luck!

Maximum Number of Pages and File Size for PDFs

Assuming that your computer has ample CPU, memory,and storage, how many pages and what file size does Adobe recommend that you limit a single PDF to using Acrobat Pro XI in order to avoid any issues.

I don't know whether there's a limit on number of pictures you can add to a book
as long as they are contained in 100 pages, which is the maximum photo pages on a book.
