Better Certification Board recommendations (Request for comments)

Now for something completely differerent:
Jordan, I appreciate what you tried to do with the Solutions for Review thread but... The latest exchanges (and a few others) on this thread I feel demonstrate why the "Mega-Thread" has already outlived its usefulness. There a a lot of good tidbits and side discussions buried in this thread that would be much more searchable and cohesive if the posters started their own threads.
Perhaps some new board suggestions for effectivness could be floated in place of the "Sample Exam Solutions for Review"?
Tips on CLD Solutions for review:
Start a new thread - indicate there will be a CLD example for review in the subject line.
For follow-up discussions on critique points start a new thread with a link to the example and a subject about the point under discussion.
This should allow the frequent fliers on this board the chance to develop a useful body of theads where specific points related to Cert specific preparation and concepts can be gathered and easily cross linked by the heavy hitters (And who knows, easilly searched by the certification candidates)
As the board grows I would hate to lose some "gems" in the noise. If we get together now, to think about what this boards goals are we can maximize our return on investment in supporting certification.
All comments welcome. Jordan, please consider floating this discussion for maximum visibility.
Jeff

I think that's a great idea - centralise the submissions and decentralise the critiques.
Another idea to improve the Certification Board might be to introduce subforums for each of the various types of certification (CLAD, CLD, CLA, etc.).

Request for Comments and Experiences with Streams Advanced Queuing

Hi,
I would like to get some feedback about what your experiences with Streams Advanced Queuing. What do you like about it? What don't you like? How do you use it? What features would you love to see in it? Please post to the forums. Thanks!

I love the new homeless Instant Client! I wish we had it years ago. Some comments:
1) The MS ODBC administrator GPF's (blows up) when trying to configure a new data source using the new Oracle IC drivers. Have to hand-edit the registry.
2) I heartily agree with the request that the new client install without requiring the normal Oracle installer. It's just too bloated for easy deployment. I'd rather hand install the files than to have to use that. Also, .zip not .jar please.
3) Need better documentation on the connection string options. It took me 3 weeks to figure out that what used to be scott/tiger@mydb is now scott/[email protected]:1524/mydb.xxx.yyy (it's looking for the GLOBAL_NAME, not the SID and TNSPING won't show you that! Doh!)
4) Please let us specify a range of ports (e.g. :1521-1524) and let it figure out where the SID is on that machine. We move ours around and don't want to update hundreds of clients with hardcoded command lines.
5) Maximum backward compatibility, please! It's not easy moving all those Oracle apps to 8.1.7.4+ databases, yet, but my old OCI client programs should not have to care. I don't want to have 2 SQL*net driver stacks on my PC's.
Thanks -- I'll be watching for new features.

[SOLVED] EurKEY PKGBUILD request for comments

'sed' and 'awk' are neither build nor run-time dependencies, both are install dependencies, but I did not find a proper option for that.
The (un-)install-scripts are taken from the Debian source, however with deb-packages it is obviously possible to abort pre/post_remove on failure (here used if the keyboard layout is still in use => no uninstall). I did not find a proper way to accomplish this with PKGBUILD install scripts.
Both scripts a rather long, but in other review requests forum veterans preferred to have scripts posted here instead of a link to AUR or pastebin. If it's nevertheless wrong I will relocate the scripts.
Thanks in advance.

If you still want to modify the XML, I would use xmlstarlet instead of awk/sed. I haven't tested the following scripts so they will probably need some debugging but they should give you a general idea of what I would do.
The post remove script would be reduced to:
set -e
# xpath selector to select layouts that are named eurkey
xpath='/xkbConfigRegistry/layoutList/layout/configItem/name[text()="eurkey"]/../..'
for file in /usr/share/X11/xkb/rules/{base,evdev}.xml; do
[[ -f "$file" ]] && xml ed --inplace -d "$xpath" "$file"
done
And the post install script would become:
set -e
xpath='/xkbConfigRegistry/layoutList/layout/configItem/name[text()="eurkey"]'
for file in /usr/share/X11/xkb/rules/{base,evdev}.xml; do
if [[ ! -f "$file" ]]; then
echo "File $file is not a regular file (skipped)"
elif xml sel -t -c "$xpath" $file >/dev/null; then
echo "File $file already constains eurkey (skipped)"
else
echo "processing $file"

W530 System Board Picture Request (for accelerometer type)

I'm looking for the inscription (make/model) of the APS chip (accelerometer) for the W530. My haunch is that it's an Analog Devices ADXL325. The location should be at item C in the image below from the 530 System Board Assembly page. Any help would be appreciated! I'm also curious to know if this is being used in other 4/500 series systems and elsewhere in the Thinkpad line.
What's on your Thinkpad? T42 2379-R9U, T61 6460-DWU, W530 2436

Version 2.02 of the Maintenance Utily does not give the options shown in the T440 Maintenance manual.
Using version 1.83 gives option compatible with the manual but it is requesting a serial starting with 1S and has 16 characters
Would appreciate some help

Blog not "processing" requests for comment.

New issue for me with blogging. When site visitors attempt to add a comment, they receive this message:
We're sorry. We are having a problem processing your request.
I go the iWeb and re-publish. It works once and then goes back to "problem processing" message.
HELP PLEASE!

There is a solution for that problem. First make sure that the 'Leave Comments' checkbox in your inspector is actually checked. Then go the Files Menu and use the 'Publish All to MobileMe' Option. After you're done publishing make sure that your users go to the right URL. Your Site exists twice... under your .Mac URL and under the new Mobile Me URL. Make sure that your user got the the ...//web.me.com... URL. That should take care of the problem.
Hope that helps!

Request for comment - inventory synchronization

Representing product manager for zed E-Commerce I'm inviting anyone who is familiar with Web tools to provide feedback on the following proposed functionality.
Inventory synchronization in web tools in the past has always been a point of contention and now that we can move forward with features and enhancements to the product we would like to gain your insight on how you would like to see this functionality improved.
Currently in web tools there is a calcuation that is done upon every synch between B1 and Web tools that determines the value that is used to show whether an item in web tools is "out of stock". This has several implications, one being that the item is then displayed on the customer facing site with a warning icon and text is shown on the checkout page indicating that an item is out of stock.
The calculation that is run is On Hand - Commited + On Order. Meaning if you have 10 items on hand, 11 of them have been ordered by customers, and 4 more are on order to be delivered from a vendor the number shown in web tools will be 3, and the display of the item will not show "out of stock" on the site.
One of the things being considered is having the option of using this query as it stands or to use an alternate query of On Hand - Commited and not include On Order, because the timing of the On Order items might be weeks and it is not preferrable to take orders when there is no in house quantity on hand.
Another option would be to have the ability to choose if when an item is out of stock, to automatically make it unavailable on web, which is a UDF on Item Master, thereby hiding it from display on the commerce site, and if a user has it in their cart, they must remove it before checking out(current functionality)\
Let us know your thoughts,
Thanks
-Bryce Blilie
otherwise now known as guest

Hi Bryce,
Certainly from my experience so far no customer wants the count / availability flag determined on the basis of available stock in B1 ( On hand - customer orders + supplier orders ). I have had to customise the count to exclude the supplier orders in order to provide a 'free stock' figure The option to select the calculation method would be welcome.
It may be useful to consider whether some options can be built into the availablity text which is currently based on the above figure. The 'In stock' and 'not In stock' is limiting and confusing as it is currently based on 'available stock'.
These days it is much more common to find some gradation and you might want to consider some mechanism for allowing options depending on the stock count for example:
not in stock    ( based on free stock )
less than x     /   low stock please call for availability ( where x is at or below minimum stock )
sold out   / y in z days ( where y is supplier orders and z is based on lead time)
The option to remove an item based upon the free stock would also be welcome although I have not yet been specifically asked for it

Request for developers to include the Dell Quadro FX 3450 in their beta linux flashplayer for 10.1

request for developers to include the Dell Quadro FX 3450 in their beta linux flashplayer for 10.1. i'm guessing it wouldn't be hard to do. its the same chip that is used in the Nvidia Geforce 6800. It has NV42GL core processor. please don't leave this device behind, any acceleration that can be done to the existing flash player would definitely count, as great.
thank you

Something keeps trying to download on my mac and I don't know what it is. It is not in the apple store and just comes out nowhere and request for my password to download something and I don't know what it is. How to make this stop? It pops up every single day.

Erica,
     I can, with 99.99% certainty, tell you that you are absolutely right in not wanting to download or install this "Helper," whatever it is (but we can be equally certain it would not "help" anything).
     I cannot comment as to Oglethorpe's recommendation of 'adwaremedic'; I am unfamiliar with it. His links to the Apple discussion and support pages warrant your time and attention.
     It might be really simple -- Trying looking in your Downloads folder, trash anything that you don't know with certainty is something you want to keep, and then Secure Empty your Trash. Then remove the AdBlock extension, LastPass, and Web of Trust extensions to Safari and re-boot. If the issue goes away, still be extraordinarily careful in the future.
     Unfortunately, it's probably not going to be that simple to get rid of, in which case I'd then try the line by line editing in HT203987.
     I have no further suggestions (other than a complete wipe and re-install...but that's a pain because trying to restore from Time Machine would simply ... restore the Mal).
   For the rest of us, please post when you find a solution.
     Best.
     BPW

Request for detailed acts to upload Work center, BOM, Routing data in LSMW

Hello PP ANgels,
Request for detailed actions to upload Work center/Resource, BOM, Routing/Recipe data in LSMW.
Thanks in advance

Sanjay,
In the forum I found that you had used some "drops", that require a password to view.
In these forums, the only links I post are public (help.sap.com) and from SAP support (service.sap.com/support). SAP Support is mostly available only to customers and partners of SAP. If you meet these criteria, and need a login for the SAP support site, contact the license administrator for your company's SAP licence (this is usually a Basis person). If you cannot locate this person in your company, contact Service Marketplace directly (service.sap.com/mp). Alternatively you can contact your local SAP Sales office and speak to your account administrator.
Maybe it would be a better idea to group all standard solutions in one place.
I expect it will be so...in Nirvana. Here, life still entails suffering.
With respect to your detailed questions, I would have a hard time answering, I have never used recordings in LSMW to create work centers, I always use standard batch/direct input. I suspect that the VGEXX items are the units of measure from CRHD, I suspect LARXX items are activities from CSSL, and I couldn't comment on FORXX items without doing some research.
This is the SCM PP forum. You might get more answers posting this in the ERP PP forum SAP ERP Manufacturing - Production Planning (SAP PP) , since work centers/routings/recipes/BOMs are more or less irrelevant in SCM.
Sorry I couldn't be of more assistance.
Best Regards,
DB49

Request for IVL

how to create request for IVL (/OBIZ/SAPMZFT_SALDUEV32) report

Some time ago I was running a similar setup, but the firewall was an ASA, not a Juniper.
Some comments:
You shouldn't disable NAT-transparence. It should work with the default-setting which is "enabled"
The firewall only has to allow UDP/500 and UDP4500. It will never see any other traffic between the hub and spoke.
The firewall shouldn't do any inspections etc. on the traffic to the hub.
You shouldn't use wildcard-PSKs. The better solution is to use digital certificates.
You probably need some MTU/MSS-settings like "ip mtu 1400" and "ip tcp adjust mss 1360".
For running ospf through DMVPN make sure the Hub is the DR and set the network-type to broadcast.

A weird request for some help in mainboard OS X

I was thinking about getting MSI P35 NEO but before buying it need find some users that have some experience with installing OS X (osx86). And maybe a better MSI board would be recommended.
Want to know if this board and chip set is fairly compatible for for OS X install. I've used the 975x PPUE and it seems ok with a few minor issues. But need something better.

I think you should also try asking in our OS section.

When I try entering a new event in iCal on my MacBook Air, I get an error message popping up on my screen that says:
The server responded with “502”
The request for account “iCloud” failed.
The server responded with “502” to operation CalDAVSetPropertyQueueableOperation.
The request for account “iCloud” failed.
I am then given the option of staying Online or going Offline.
Can anyone help me?

Hello b.krushel,
Thank you for using Apple Support Communities
Any number of things could cause this issue, so I would recommend this article named iCloud: Troubleshooting iCloud Calendar found here http://support.apple.com/kb/TS3999.
These sections in particular:
General Troubleshooting
Make sure there are no current issues listed on the System Status that affect iCloud Calendar. The System Status is located on the iCloud Support webpage.
Make sure you have fully enabled iCloud Calendar for the client you are using (for more setup and troubleshooting information on iOS, OS X, Windows and iCloud.com, see the additional details below).
Check to see if the issue you are seeing is covered in iCloud Help. To search iCloud Help, visit help.apple.com/icloud.
Check your settings and preferences as something may not be set up correctly. For example, having incorrect date and time settings can cause issues which are easily resolved by entering the appropriate settings.
Troubleshooting Calendar on OS X Mountain Lion (iCal on OS X Lion)Note: For instructions on setting up iCloud Calendar with Calendar or iCal on your Mac, see iCloud Setup.If you are having trouble with Calendar or iCal on a Mac and you are using iCloud Calendar, try each of these steps, testing after each to see if the issue is resolved:
Make sure you are using OS X Lion v10.7.2 or later. Click here for help verifying the version of OS X you are using.
Make sure your computer is online. Attempt to view www.apple.com and iCloud.com. If you can't connect to the Internet, your iCloud calendars and events will not update in iCal. Click here for more information about troubleshooting your Internet connection.
Verify that your iCloud member name is entered into the iCloud Preference pane in System Preferences. See iCloud Setup for more information about setting up iCloud on a Mac.
Make sure you enter and update calendar information in the iCloud section of Calendar or iCal. Only calendars and events in the iCloud section of the Calendar or iCal Calendar list will be pushed to iCloud. Both Calendar and iCal for the Mac support the display of and interaction with multiple accounts and datastores, for example, iCloud, On My Mac, Exchange, Google, and so on. This makes it easy to create or modify events or calendars in a section of Calendar or iCal that may not be updating iCloud. Learn more about moving local calendars to iCloud.
In some cases, you may find that you have data duplicated in both the local On My Mac and the iCloud sections of Calendar or iCal. Learn more about resolving this issue.
You can make the iCloud calendar your default calendar for all new events. In Calendar on OS X Mountain Lion, choose Calendar > Preferences > General, or in OS X Lion, choose iCal > Preferences > Generaland under the Default Calendar heading, select one of the Calendars under the iCloud heading. Close the Preferences window to save this change.
If recent changes simply don't appear, try forcing Calendar or iCal to refresh by selecting Refresh All from theCalendar menu.
Make sure your account was successfully created in Calendar on your Mac (or iCal). After upgrading to iCloud Calendar, you may need to quit and reopen Calendar (or iCal). To confirm your account is configured correctly in iCal:
Open Calendar (or iCal).
Open Calendar (or iCal) Preferences.
Click Accounts. You should see an account with your iCloud member name entered.
Turn iCloud Calendars off and back on
Quit Calendar (or iCal).
Choose Apple () menu > System Preferences > iCloud.
Remove the checkmark in the checkbox next to Calendars.
Close System Preferences and wait about a minute.
Open System Preferences and choose iCloud.
Replace the checkmark next to Calendars.
Close System Preferences.
Open Calendar (or iCal) and test to see if the issue has been resolved.
Restart your computer. This may sound simple, but it does reinitialize your network and application settings and can frequently resolve issues.
Take care,
Sterling
