Best practices for making space on hard drive?

My relatively trusty ol' 466 mhz G4 is bogging down. I am showing 9.77 GB out of 28.6 capacity. I have the Adobe CS programs and do a lot of Photoshop work. I decided to clean house and dump as much stuff as I can, including the older programs (Adobe Design Suite, Virtual PC, etc.) I don't use these programs anymore, and have the original CD's, so assume there is no reason to take up space with them. My questions are:
1- Is there a general rule for optimal functioning of a Mac in terms of the % of HD space that should be available?
2- What is the difference between regular 'empty trash' and 'secure empty trash'?
3- I bought the LaCie for backing up the hard drives and files. Am using iMSafe, but am a little spooked by the warmings that "removing obsolete files from the destination could result in data loss". Any suggestions?
PowerMac G4 Digital Audio 466 mhz Mac OS X (10.3.9) 896 MB SDRAM, 30GB HD, 75 GB additional int. HD, and a 120 GB LaCie external HD

10-15% free HD space. So having 25-30% free should not pose a problem?
That should be fine for now, but you know how quickly space can disappear, and the less space you have the slower the system will become.
Paranoid that something trashed will be found? Or that something trashed will be lost, then needed?
Something trashed will be found. If you're using your computer in an everyday way and you delete something you later decide you really want, even using the most sophisticated data recovery programs you can only find stuff that hasn't already been written over.
How does a backup program (such as iMSafe) decide which files are "obsolete"? I hardly know myself! So how do I know if it is OK to trust the program to decide?
Personally, I don't like the fact that it does this, but I believe it is simply comparing the original with the copy. If you've deleted the original, then it wants to know if the backup file is now obsolete.
I would suggest you consider something easier to use. Have a look at ChronoSync and see what you think.

What is current best practice for backing up a hard disc?

With the availability of various cloud applications, I would like to know if backing up an hard disc is now best done to the cloud? For example, should you buy space in Amazon.com, or somewhere else on the Internet, and then backup your hard disc to that space? Could you backup an entire harddisc to iCloud? Your knowledge and experience is greatly appreciated. Thank you.

iCloud doesn't provide storage except for pictures
and your music, and only under limited circumstances.
Merchant online backup services such as Carbonite
and others exist for this reason. And you can sync
your files with/to Dropbox. Many users keep a local
copy of their files on  Time Machine or other hard
drives in addition to remote backups (in case of a
fire or other event compromising the local solution).
Backup software or cloning programs are useful in
all the above. You have to work at backup a bit -
it's like insurance, a bit of expense now to save a
lot of heartache later.Good to see you're determined
to forestall potential disaster - too many lack it.
Good luck, Tom

Best practices for making the end result web help printable

Hi all, using TCS3 Win 7 64 bit. All patched and up to date.
I was wondering what the best practices are for the following scenario:
I am authoring in Frame, link by reference into RH.
I use Frame to generate PDFs and RH to generate webhelp.
I have tons of conditional text which ultimately produce four separate versions of PDFs as well as online help - I handle these codes in FM and pull them into RH.
I use a css on all pages of my RH to make it 'look' right.
We now need to add the ability for end users to print the webhelp - outside of just CTRL+P because a)that cuts off the larger images and b)it doesn't show header, footer, logo, date, etc. (stuff that is in the master pages in FM).
My thought is doing the following:
Adding four sentences (one for each condition) in the FM book on the first page. Each one would be coded for audience A, B, C, or D (each of which require separate PDFs) as well as coded with ONLINE so that they don't show up in my printed PDFs that I generate out of Frame. Once the PDFs are generated, I would add a hyperlink in RH (manually) to each sentence and link the associated PDF (this seems to add the PDF file to the baggage files in RH). Then when I generate my RH webhelp, it would show the link, with the PDF, correctly based on the condition of the user looking at the help.
My questions are as follows:
1- This seems more complicated than it needs to be. Is it?
2- I would have to manually update every single hyperlink each time I update my FM book, because I am single sourcing out of Frame and I am unable (as far as I can tell) to link a PDF within the frame doc. I update the entire book (over 1500 pages) once every 6 weeks so while this wouldn't be a common occurrence it will happen regularly, and it would be manual (as far as I can tell)?
3- Eventually, I would have countless PDFs inside RH. I assume this will eventually impact performance. So this also doesn't seem ideal?
If anyone has thoughts/suggestions on a simpler way or better way to do this, I'd certainly appreciate it. I have watched the Adobe TV tutorial on adding a master page but that seems to remove the ability to use a css across all my topics and it also requires the manual addition of a manual hyperlink to the PDF file, so that is what I am proposing above, anyway (not sure the benefit, therefore).
Thanks in advance,
Adriana

Anything other than CTRL + P is going to create a lot of work so perhaps I can comment on what you see as drawbacks to that.
a)that cuts off the larger images and b)it doesn't show header, footer,
logo, date, etc. (stuff that is in the master pages in FM).
Larger images.
I simply make a point of keeping my image sizes down to a size that works. It's not a problem for me but that doesn't mean it will work for you. Here all I am doing is suggesting you review how big a problem that would be.
Master Page Details
I have to preface this with the statement that I don't work with FM. The details you refer to print when they are in RoboHelp master pages. Perhaps one of the FM users here can comment on how to get FM master pages to come through.

Best practice for making changes to Oracle apps business views and BAs/fold

HI
The oracle BI solution comes with pre-defined Business Views- database views and Business Areas and folders. If we want to customize those database views or BAs and folders what will be the best practice in order to avoid losing it during any upgrades.
For ex Oracle out-of box Order Management BA that we are using heavily needs some additional fields to be added to Order Header and Order Lines folders and we also want to add some custom folders to this BA.
If we do the changes to the database views behind this BA would they be lost during the upgrade or do we have to copy(duplicate) those views, updated them and create a custom BA and folders against those views.
Thanks

Hi,
If you are adding new folders then just add them to the Oracle Business Area. The business area is just a collection of folders. If the business area was changed in an upgrade the new folder would not be deleted.
If you want to add fields to the existing folders/views then you have 2 options. Add the field to the defining base view (these are the views beginning OEBV and OEFV) and then regenerate the business views. This may be overwritten if the view is upgrade but this is unlikely.
Alternatively, copy the view to create a new version and then map the old folder to the new view and refresh. You may need to re-map the folder if the folder is upgraded, but at least you have a single folder used by both Oracle and custom reports.

Best Practice for making material obselete

Hai Experts,
Could any one please advice me what s the best practice to make a material obselete. Is there any best practice or incase if it is not there what would be the diff ways it cant be made obselete.
Please advice me on this.
Thanking you in advance

Archiving is a process, rather than a transaction. you have to take care that you fulfill local laws and retain your data for x years for internal and external auditors.
archiving requires customizing, you have to tell SAP where your archive is and what name it has and how big it can be, and when (definition of retention period) a document can be archived.
you have to talk with your business how long they want the data keep in the production system (this depends on how long they need to run reports on this data)
you have to define who can access the archived data and how this data is accessed.
Who runs archiving?
Tough question. Data owner is the business, so they should run.
But archiving just buckets fragments your tables.
so many companies have a person who is fulltime responsible for archiving and does it for all business units and organisations.
Archiving is nothing what can be done "on the fly", you will encounter all kind of errors, processes that are not designed well will certainly create a lot problems in archiving and need to be reworked.
I had an archving project with 50 days project time, and could develope guidelines to archive about 30 different objects. there are 100 more objects possible, and we have still not archived master data like material, vendors and customers because of so many dependencies and object that need to be archived prior to those objects.

[Ask] Best practice for making pools with CAM.

Dear all,
there's a few things I want to ask:
Condition:
- I have 48 disk with 300GB each and want to make some pool that contains /ctl , /archive , /data , /backup , /redo
- i use software common array manager 6.9
- based on the information I got, when use more than 1 pool, when the data is processed is faster then if only make 1 pool.
Question:
- which/what is the best practise when the data is spread out in several pool? my target is iops < 4ms
- How many pool do I make?
- How many hard drive is set in 1 pool?
Thank you in advance.

What is the best approach for transferring DAT to Hard Drive?

Hi,
I've got 10 60 min DATS of my 1970s rock band transferred from live reel to reel recording of gigs. I want to get rid of the DAT machine on Ebay and before I do get these DATS transferred for storage on CDs or DVDs.
I have an external hard drive to transfer to before burning to disc.
Does it make sense to use Logic Pro to transfer the DATS through the computer to the hard drive? Or is there a better / easier / faster way to do it?
I'll want to go back and find songs later and use Logic Pro to EQ and mix them onto a CD by track at some point.
Each DAT is 60 minutes worth of material and ideally I'd like to be able to run through the transfer and mark where songs start as the "in between" stuff is there also.
Thanks,
Bob

Hey, thanks for the reply.
Few more comments....
Could you suggest a Mac stereo editor/recorder.
What is s/pdif? I'm new to computer recording.
Slave recorder to the DAT....I'm hooking the DAT into the iMac through an interface...is this what you mean?
Got you on separate recordings....I want to do that later...Just get the whole tape onto the hard drive then onto a CD or DVD. When I have more time I'll run through and find songs, etc.
Again, thanks,
Bob

Best practice for making a report of 10,000 to 20,000 rows(OBIEE 10.3.4.1)

My Scenario is like this:*
Hi i have 2 fact tables fact1 and fact 2 and four dimension tables D1,D2,D3 ,D4 & D1.1 ,D1.2 the relations in the data model is like this :
NOTE: D1.1 and D1.2 are derived from D1 So D1 might be snow Flake.
[( D1.. 1:M..> Fact 1 , D1.. 1:M..> Fact 2 ), (D2.. 1:M..> Fact 1 , D2.. 1:M..> Fact 2 ), ( D3.. 1: M.> Fact 1 , D3.. 1:M..> Fact 2 ),( D4.. 1:M..> Fact 1 , D4 ... 1:M..> Fact 2 )]
Now from D1 there is a child level like this: [D1 --(1:M)..> D1.1 and from D1.1.. 1:M..> D1.2.. 1:M..> D4]
Please help me in modeling these for making a report of 10,000 rows and also let me know for which tables do i need to enable cache?
PS: There shouldn't be performance issue so please help me in modeling this.
Thanks in Advance for the Experts who are helping me for a while.

Shudn't be much problem with just these many rows...
Model something like this only Re: URGENT MODELING SNOW FLAKE SCHEMA
There are various ways of handling performance issues if any in OBIEE.
Go for caching strategy for complete warehouse. Make sure to purge it after every data load..If you have aggr calculations at higher level then you can also go for aggregated tables in OBIEE for better performance.

Hope this is clear...Go ahead with actual implementation and lets us know incase you encounter any major issues.

Best practice for making a mirror of the system disk

I've got an HP ML115 machine that I'm installing Solaris 10 on. It has four disks: a 160GB (boot drive), a 300GB spare, and two 1.5TB drives. I've made a mirrored pool of the two 1.5TB drives. I'd like to create a mirror of the 160GB boot drive (I realise I'll lose some space). However, I'm unsure of how to do this. Attempting to create a mirror (zpool create -f bootmirror c0t0d0 c0t1d0) tells me that the partitions are mounted.
Any ideas on what the best way to achieve this is, please?

What filesystem type is root currently UFS or ZFS.
If its currently UFS, you will have to use SVM for mirroring. A UFS root can't be converted to a ZFS root.
If its already a ZFS root just not mirrored, it should be simple. Just add the disk to the pool to "promote" it to mirrored.
You do that with a zpool attach command.

Best practice for dual SSD RAID0 boot drive configuration

What is optimal stripe size for RAID0 OS/Boot Drives in OSX Software RAID?

You are talking about SSD too.
Usually the default or 16/32k would be fine for all those small frequent I/Os.
RAID though can affect SSD TRIM and it may depend on the SSDs. There are RAID optimized editions.

Best practice for making database connection to Forms 10 apps?

Hi
To upgrade our Forms applications we are moving from version 3 to 10.
Our old system runs Forms applications and the connection to the database is based on the individual user. This means that any tables or views used require that the user has specific access granted to them. We have a bespoke system to manage this which generates scripts (GRANT statements) based on lists of tables and users and their appropriate access.
I have concerns that managing the table access for thousands of individual users in the Forms 10 environment is going to be technically difficult, especially with RADs to consider. Is it feasible to generate and frequently refresh RAD scripts to maintain the current list of users and their permissions?
I am trying to decide if it is better to:
A) Connect with the same database user (such as "APP_USER") which has access to everything
or
B) Connect with individual usernames/passwords
Currently, the individual user database passwords are generated weekly and users have means to obtain them (once signed in) rather than setting and remembering them. Some views refer to the Oracle system parameter "USER" to decide what data is returned so this functionality would need to be preserved.
Any help is greatly appreciated, especially if you can tell me if option A or B is how you connect at your site.

Thanks for the advice so far.
It would appear that connecting with individual usernames is not a fundamental error, which I was concerned about.
Will it still be necessary to create and refresh RAD scripts, or is this only an issue when using OID? We have OID here already because we have a website using Oracle Portal. The sign-on process for this connects to Active Directory for authentication.
I do not like the idea of having to schedule a refresh of RAD scripts, perhaps 3 times a day, just to keep it current. I do not think the RADs are expected to change as frequently as this, but perhaps other forum members have experience of this?

Best practice for making form read-only at certain steps in process?

I have a process with a single form and 4 Assign Task operations. During Assign Task operations 1 and 3, the form is edited. During Assign Task operation 2 and 4, it should be read-only (it is reviewed and acknowledged, but not changed). There is no single criteria in the form data that indicates whether a form should be read-only or not -- this is only signaled by the step in the process. What is the best way to manage the read-only state?
Is there a way to make the form read-only via a setting in Workbench, or should I do this via a script in the form?
Thanks!
Toby

Best Practices for Using Photoshop (and Computing in General)

I've been seeing some threads that lead me to realize that not everyone knows the best practices for doing Photoshop on a computer, and in doing conscientious computing in general. I thought it might be a good idea for those of us with some exprience to contribute and discuss best practices for making the Photoshop and computing experience more reliable and enjoyable.
It'd be great if everyone would contribute their ideas, and especially their personal experience.
Here are some of my thoughts on data integrity (this shouldn't be the only subject of this thread):
Consider paying more for good hardware. Computers have almost become commodities, and price shopping abounds, but there are some areas where spending a few dollars more can be beneficial. For example, the difference in price between a top-of-the-line high performance enterprise class hard drive and the cheapest model around with, say, a 1 TB capacity is less than a hundred bucks! Disk drives do fail! They're not all created equal. What would it cost you in aggravation and time to lose your data? Imagine it happening at the worst possible time, because that's exactly when failures occur.
Use an Uninterruptable Power Supply (UPS). Unexpected power outages are TERRIBLE for both computer software and hardware. Lost files and burned out hardware are a possibility. A UPS that will power the computer and monitor can be found at the local high tech store and doesn't cost much. The modern ones will even communicate with the computer via USB to perform an orderly shutdown if the power failure goes on too long for the batteries to keep going. Again, how much is it worth to you to have a computer outage and loss of data?
Work locally, copy files elsewhere. Photoshop likes to be run on files on the local hard drive(s). If you are working in an environment where you have networking, rather than opening a file right off the network, then saving it back there, consider copying the file to your local hard drive then working on it there. This way an unexpected network outage or error won't cause you to lose work.
Never save over your original files. You may have a library of original images you have captured with your camera or created. Sometimes these are in formats that can be re-saved. If you're going to work on one of those files (e.g., to prepare it for some use, such as printing), and it's a file type that can be overwritten (e.g., JPEG), as soon as you open the file save the document in another location, e.g., in Photoshop .psd format.
Save your master files in several places. While you are working in Photoshop, especially if you've done a lot of work on one document, remember to save your work regularly, and you may want to save it in several different places (or copy the file after you have saved it to a backup folder, or save it in a version management system). Things can go wrong and it's nice to be able to go back to a prior saved version without losing too much work.
Make Backups. Back up your computer files, including your Photoshop work, ideally to external media. Windows now ships with a quite good backup system, and external USB drives with surprisingly high capacity (e.g., Western Digital MyBook) are very inexpensive. The external drives aren't that fast, but a backup you've set up to run late at night can finish by morning, and if/when you have a failure or loss of data. And if you're really concerned with backup integrity, you can unplug an external drive and take it to another location.
This stuff is kind of "motherhood and apple pie" but it's worth getting the word out I think.
Your ideas?

APC Back-UPS XS 1300. $169.99 at Best Buy.
Our power outages here are usually only a few seconds; this should give my server about 20 or 25 minutes run-time.
I'm setting up the PowerChute software now to shut down the computer when 5 minutes of power is left. The load with the monitor sleeping is 171 watts.
This has surge protection and other nice features as well.

Best practice for PK and indexes?

Dear All,
What is the best practice for making Primary Key and indexes? Should we keep them in the same tablespace as table or should we create a seperate tableapce for all indexes and Primary Key? Please note I am talking about a table that has 21milion rows at the moment and increasing 10k to 20k rows daily. This table is also heavily involved in daily reports and causing slow performance. Currently the complete table with all associated objects such as indexes and PK is stored in one seperate tablespace. If my way is right then please advise me how can I improve the performance of retrival or DML operation on this table?
Thanks in advance..

Well, thanks for valueable advices... I am using Oracle 8i and let me tell you exact problem...
My billing database has two major tables having almost 21 millions rows each... one has collection data and other one for invoices... many reports are showing the data with the joining of Customer + Collection + Invoices tables.
There are 5 common fields in between invoices(reading) and collection tables
YEAR, MONTH, AREA_CODE, CONS_CODE, BILL_TYPE(adtl)
My one of batch process has following update and it is VERY VERY SLOW:
UPDATE reading r
SET bamount (SELECT sum(camount)
FROM collection cl
WHERE r.ryear = cl.byear
AND r.rmonth = cl.bmonth
AND r.area_code = cl.area_code
AND r.cons_code = cl.cons_code
AND r.adtl = cl.adtl)
WHERE area_code = 1
tentatively area_code(1) is having 20,000 consumers
each consuemr may have 72 invoices and against these invoices it may have 200 rows in collection tables (system have provision to record partial payment against one invoice)
NOTE: Please note presently my process is based on cursors so the above query runs for one consumer at one time but just for giving an idea I have made it for whole area.
Mr. Yingkuan, can you please tell me how can I check that the table' statistics is not current and how can I make it current. Is it really effect performance?
