Dual ethernet query - any point?

Hi,
I've got a Mac Pro and have a spare port available on my modem/router so could plug another network cable into the ethernet port. I don't fully understand the benefit of having the two ports, certainly not for a home user. Could someone explain if have two connections would help me, or its it overkill for your basic home network?

Not sure if this helps or makes sense to anyone, but one use I have found for the dual Ethernet ports involves using Parallels with the following setup:
(1) Connect each port on the Mac Pro to a switch and/or router/switch. You can obtain a different IP address for each port via DHCP or, if necessary, statically (use Preferences -> Network). The port labeled 1 is device en0 and the port labeled 2 is device en1, as easily verified with /Applications/Utilities/Network Utility -> Info. (By the way, if you have Airport Extreme installed, it is assigned device en2.)
(2) Using System Preferences -> Network, assign Built-in Ethernet 1 highest priority (using Network Port Configurations). Then, your Mac Pro will use this port and IP address as its primary internet connection.
(3) If using Parallels, you can assign the en1 (i.e., Built-in Etherner 2) port to the Windows network adapter using the Configuation Editor -> Network Adapter Options -> Bridged Ethernet and select en1 (or you can share en0 or use Airport Extreme, en2, if you have it).
(4) This configuration will give you independent simultaneous network connectivity on your Mac and on the Virtual Windows machine (Parallels), each with its own separate IP address, and ability to (depending on your router's configurability) enable/block certain ports, as one example.
Hope this helps,
Stu

Query to bring 6 rolling pay check date at any point of time

Hi,
we have a date dimension dim_date which is having calendar date. I need to write a query which will always bring 6 rolling pay check dates ant any point of time. there is 14 days gap between each pay check date and it is fall on friday. please take below example as a reference and help me to write query as per my requirement. thanks in advance.
pay check date example:
3/23/2012
3/09/2012
2/24/2012
2/10/2012
1/27/2012
Thanks
Jay.

The to_char function with 'D' mask returns the day of the week:
Sunday is 1, we need to sum 6-mod(1,7)=5 for next friday
Monday is 2, we need to sum 6-mod(2,7)=4 for next friday
Tuesday is 3, we need to sum 6-mod(3,7)=3 for next friday
Wednesday is 4, we need to sum 6-mod(4,7)=2 for next friday
Thursday is 5, we need to sum 6-mod(5,7)=1 for next friday
Friday is 6, we need to sum 6-mod(6,7)=0 for next friday (well, current or next friday)
Saturday is 7, we need to sum 6-mod(7,7)=6 for next friday
So, we always need to sum 6-mod(to_char(sysdate, 'D'), 7) to found the current or next friday:
SQL> select to_char(sysdate+6-mod(to_char(sysdate, 'D'), 7), 'yyyy-mm-dd') next_friday from dual;
NEXT_FRIDAY
2012-02-17
And, adding other 14 days for each next rolling pay chack, we have:
SQL> select to_char(sysdate+6-mod(to_char(sysdate, 'D'), 7), 'yyyy-mm-dd') rolling_dates from dual
2 union all
3 select to_char(14+sysdate+6-mod(to_char(sysdate, 'D'), 7), 'yyyy-mm-dd') rolling_dates from dual
4 union all
5 select to_char(14+14+sysdate+6-mod(to_char(sysdate, 'D'), 7), 'yyyy-mm-dd') rolling_dates from dual
6 union all
7 select to_char(14+14+14+sysdate+6-mod(to_char(sysdate, 'D'), 7), 'yyyy-mm-dd') rolling_dates from dual
8 union all
9 select to_char(14+14+14+14+sysdate+6-mod(to_char(sysdate, 'D'), 7), 'yyyy-mm-dd') rolling_dates from dual
10 union all
11 select to_char(14+14+14+14+14+sysdate+6-mod(to_char(sysdate, 'D'), 7), 'yyyy-mm-dd') rolling_dates from dual;

Setup Dual Ethernet (Snow) using Windows XP

Is it possible to configure a Dual Ethernet (Snow) Airport base station using only a pc running Windows XP? If so, which version of the admin utility should I use and what's the exact process in order to get things setup?
We've performed a hard-reset but it will not allow us to update the base station using 4.2 for Windows, because there's an error connecting to it via ethernet.
Thanks!

Thanks. That has helped point us in the right direction. In addition, I found this info particularly helpful in order to set the TCP/IP settings in the Network control panel:
http://docs.info.apple.com/article.html?artnum=106685
After changing those settings, we were able to configure and update the base station.
However, after putting the TCP/IP settings back the way they were (obtain IP automatically instead of manually), the PC connected via the LAN port and the wireless can't connect to the internet at all. The base settings reveal that it's using an IP address starting with 169.xxx.xxx.xxx which tells me it can't get a real IP from the cable modem. Unplugging the cable modem, base station, restarting, etc. aren't doing the trick. Oh so close. I'll keep you posted unless you have any further suggestions.

How Do I setup Dual Ethernet (Snow Saucer) base as "repeater" for Extreme

Just migrated from G4 iBook to an MBP. Currently still using my Snow Saucer (Dual Ethernet) airport base station (had to communicate with the Base using the iBook, and manually enter the MAC address of the MBP).
When I go to the trouble of setting up my Airport Extreme to become the base station to which my DSL line is connected, I also want to use the old Saucer as a "repeater" to get a better signal somewhere else.
Where are the instructions for doing this?
Also, I want to know if this may be a bad idea, because IIRC I read that if the Extreme detects a device using the "old" frequency, it will downgrade itself to that frequency, and I will lose the advantage of the Extreme for any devices which could make use of it.

However, extreme and express base stations can be configured to to act as relays and receivers for Graphite and Snow base stations.
With no setting or availability of WDS capability on the dual ethernet device, I fail to see how this would be possible.
Setting this up is fiddly because you have to configure the bridges to connect to an ABS via a MAC address.
And, the ABS must also be configured with the MAC address of the other devices in the WDS, but there are no provisions to do this.
If you want, I'll send you a link for MacTracker, which lists all models and specifications.
It might be possible to run ethernet from one of the other AirPorts, configure the dual ethernet version in "bridge mode" (if possible) and then have it create a wireless network. To be part of the "same" wireless network, it would need to be setup to use the same wireless network name, security and password as the "main" network.

Airport Dual Ethernet connecting to DSL.

My normal system is a Windows XP PC connected to 2wire dsl router from SBC. My wife has an iBook(the white one)that we are trying to get connected to the internet using an Airport Dual ethernet. THe iBook has a wireless card installed and before I moved all I did was plug the airport into the DSL router and all was well. Now what is happening is that as soon as I plug the airport into the router it I lose my PC internet connection, even more frustrating is that I still can't access the interent via the iBook.
I am totally unfamiliar with the Mac OS so this just adds to my frustration. Are there any resources/guidance/books that would help a new wireless Mac user on configuring the airport to connect to the same router as a windows PC without screwing it all up?
Any help would be awesome.

Hello, I'm new to Mac's as well, but I hope I can help narrow down the source of the problem a little.
You said "and before I moved all I did was". I take that to mean you moved from one home to another. Does that mean that you also have a new DSL service provider (which means they provided you with the DSL router you are using. A couple things to try to semi isolate the problem, or at least try to narrow it down to one device having issues.
Try to connect to the internet with each computer individually using the DSL router, one at a time. Do they both work that way?
Try connecting the airport only, then connecting to the internet with each computer individually (the other should be powered down so it doesn't try to connect when wireless becomes available {hopefully}). Do they work this way?
If they work, or one does but not the other you have provided yourself wirh a wealth of information to offer the experts (no that's not me), I'm afraid I won't be much help beyond this. The reason for this method is that you may discover that something has happened to your system(s) (hopefully not) during your move(?), or your service provider (new) may have provided you with a faulty router (just a couple of possibilities).
Another thing, have you installed any new software, or updates recently, like just before the connection stopped working.
Hope this helps.

Is there any point in a G4 render farm?

Hi all.
I've been getting quite intrested in the idea of setting up a very small render farm laterly as I have the option of getting some old G4s for free.
I currently have a 2.0Ghz DP G5 as my main mac running FCP2 and Shake and was already grabbing a G4 466 digital audio to set up as a file/print and back up server running tiger server, a postscript RIP and retrospect. I have the possibility of getting atleast one more G4 466 DA and maybe a couple of G4 400 AGPs with Gigbit ethernet cards. As the main use would be farming out DV to mpg2 compression via compressor and shake renders (though not large shake stuff to begin with as very new to this) is there any point in looking into this or am I going to need to lots of G4s to make a real improvement in render times.
Also is RAM a major consideration. For example if I got 4 G4s with say 512Mb ram would it be better runing all four or using three but nicking the fours ram to give more ram in the three machine set up?
Any advice would be appreciated
Cheers
Steve

I vote no. G4 isn't the problem so much as 400mhz is. The ram shouldn't be a problem.
But you could test if you set up Compressor on one G4. Compress a job. Compress the same job with the same settings on the G5.
If the G5 is 4 times (or even 3, since time is spent sending the render data over the network between the G4's slow system busses) as fast the single G4, a render farm will not help you.
Using the G4 and G5 together in the same cluster does not work because Compressor looks at all processors and divides the job into twice as many segments. In this case, the G5 finishes it's two segments years before the G4's and then sits around waiting. You could try splitting the G5 into 4 instances, but then you have 8 slow processors attacking your job. Not very efficient.
Good luck though. You should test the one G4 just so you know. Report back if you do.

Dual Ethernet Airport Not Broadcasting?

I have a dual ethernet Airport base station connected to a cable modem. I started having connectivity problems between the airport and my three Macs (G5, G4 Powerbook 17-inch and older G4 Powerbook 15-inch) a couple of days ago. Today none of the Macs can access the internet.
I've tried everything: using Airport Admin to reconfigure, resetting the base station, working with the cable internet ISP folks, etc. The Internet Connect interface tells me the Airport is indeed connected to the internet, but none of the Macs seem to be able to connect with the Airport. Also, hardwiring the ethernet cable to the G5 works just fine.
Any ideas?
Thanks!

I too am having the same problems with the dual ethernet airport. This happened around 3/29 as well. I have called the cable co. for dsl modem advice, the tech says its a apple problem. the apple tech says all is hooked up ok. but when the air port is connected to the dsl modem all the lights are green except the internet. will not talk to the modem. I have done a hard reset and followed all the steps.
When dsl modem is directly connected to g4 cube... all is ok.
My house has been wireless for a long time..... Please does anyone have any ideas to fix this?

Can I change my Dual Ethernet Airport from WEP to WPA?

I just read that WEP wireless networks aren't really secure, even when set up as "closed," but it appears that my Dual Ethernet Airport only allows WEP networks.
Can I change software or firmware to allow me to configure the Airport as a WPA network? My firmware is version 4.0.9 which appears to be the most current available.
Thanks for any help. I'm also having the problem with a dual core machine not automatically establishing with my closed airport network if anyone is keeping track, I've got an unanswered thread about it on the intel mac page.
Also, I apologize for posting this on the Airport for Windows page, I'm using a Mac, actually several.

Dual Ethernet Airport

I have been able to configure the ABS dual ethernet using the LAN connection, but when I disconnect the ethernet cable the imac does not see the ABS. How do I get the imac to recognize the ABS or how do I connect to the ABS?
I am using airport admin utility for graphite and snow version 4.2.5. The admin utility does not show the ABS wirelessly, but will show it while connected using the ethernet cable.
I have tried doing a hard reset, but the original name remains and does not change and the soft reset does not do anything. the middle light blinks once every second and I have followed the manuals for hard and soft reset.
How do I get the computer to recognize the ABS?

If you're sure you've configured the airport to create a new network and its not showing up wirelessly, either the wireless functions of the airport or your computer are not working properly.
If you have several computers capable of wireless, check them all to see if the airport network shows up. If not, then the airport base station may be bad. (check out those new airport extremes, they're nice )
If your computer is unable to see any networks (at other locations or in your area), then the airport software/hardware on your computer could be bad. Try:
- make sure airport is turned on in OSX
- if you have an external antenna, make sure its plugged in properly
- if you have a switch on your computer that turns on/off wireless, make sure it is turned on

ABS Dual Ethernet -- Error writing configuration during hard reset mode

This has been a full day of troubleshooting this one. After downloading the Airport Admin Utility 4.2.5, I was finally able to see the old ABS Dual Ethernet via ethernet cable plugged into the LAN port from a Macbook running 10.5.2. We don't know the password to login into the base station and a soft reset hasn't stripped the password from the base station.
So.. I got ABS into hard reset mode with the middle LED blinking once every second as described in the Apple documentation, and was able to seethe ABS from the Airport Admin Utility. HOWEVER, when I try to configure the ABS, I enter my Admin username and password, am prompted to temporarily change TCP/IP settings for this computer and then "Writing configuration..." comes up.. but a few seconds later I get an error message "An error occurred while writing the configuration."
That's it. No other explanation.
No idea where to go from here.
My network settings are set in Manual mode to the following:
IP: 192.42.249.15
Subnet: 255.255.255.0
Router: 192.42.249.13
Any ideas with this one?

If I understand your post correctly, "when I try to configure the ABS" in the second paragraph refers to clicking the Configure button while trying to reload base station software (i.e., step 16 in Apple's document titled AirPort Base Station (Dual Ethernet) : How to reload software from Mac OS X).
I suggest that in order to reload the base station software, you make sure that AirPort is inactive on your computer and that the manual network settings you described are in the "Show: Built-in Ethernet" part of Network preferences.
Beyond that, I'd recommend re-doing the hard reset, possibly multiple times if it doesn't succeed the first time.
On the other hand, if you successfully reloaded the base station software and are indeed trying to configure the base station's settings, then quit AirPort Admin Utility, restore the computer's Network Ethernet settings to Using DHCP, and reopen AirPort Admin Utility (steps 18-20 of Apple's document).

Balance Sheet translation at spot rate at ANY point in time

My client produces its financial accounts in AUD. They will have open items in AR, AP and Bank in foreign currencies. WITHOUT running periodic valuation they wish to produce a Balance Sheet at any point in time during the month applying the applicable daily spot rate to valuate the Foreign Currency open items (for reporting purposes only). I have run S_ALR_87012284 and maintained the special evaluations tab for Display Currency (AUD), Key date for translation (current date) and exchange rate type (spot rate type). However, this does not appear to be revaluating the open items in the subledger accounts to produce the balance sheet at the current spot rate. Appreciate input / alternate approach. Cheers, Dean.

Hi Chirag
As per Oracle following are the rules that has to be followed for translation.
1. For Balance Sheet Accounts (Asset & Liabilities) GL as a default uses the YTD rule.
2. For P&L Accounts you can choose between YTD and PTD rule. So in your case you can use the default PTD Rule. (Profile Option 'GL Translation: Revenue/Expense Translation Rule')
YTD Rule = (Translated Period Amount = Period-End Rate x YTD Ledger Currency Balance - Beginning Translated Balance).
PTD Rule = (Translated Period Amount = Period Average Rate x PTD Ledger Currency Balance)
Hope this helps.

Gautam

Migration status at any point of time

Hello to All,
I am running a migration scripts (which are actually a procedures) to pick the data from the source table to target
table.
My requirement is to find out the migration status at any point of time.Is there any way to do it?
Please help.
Best regards,
Pavan

Hi Pavan,
Does your source table have columns to store the status, error message?
In general, stage tables should have a status and error message column which are updated by the migration script with the status of that particular record.
You can check these columns to get the status.
For eg
select status, error_message, count(*)
from you_table
group by status, error_message;The above script will give the number of records Successfully processed, errored during migration.
Regards
Imran

After setting up my brand new Airport Express 802.11n and accidentally using it to connect my iMac to the network...my iMac no longer connects through Ethernet? Any ideas...I have tried everything without success!!

I have been using Apple technology for about 10 years starting with 1st generation iPods and our house now includes a 5 year old iMac, all versions of iPods and touches, Apple TVs (both generations) and most recently an iPad 2. I have always told family and friends that Apple technology just works. Unfortunately that stopped today. I bought a new Airport Express 802.11n to use for AirTunes around my new pool. I set it up from my iMac and accidentally used it to connect my iMac to the network for a short time. Now I can no longer connect the iMac to the network using a hard wired Ethernet cable. I have tried resetting everything possible, from hubs to routers to the Mac itself and it just will not connect to the network through Ethernet any longer. I am now a very frustrated Apple user especially when the support site says I can't use the fast path support because my product was manufactured 5 years ago...I just bought it at BestBuy yesterday. All other computers and itechnology in the house are connecting via wifi and Ethernet without any issue except from my new iMac boat anchor. Anybody who can help me??? Thanks

John, thanks for the email so quickly.
I too hope I haven't tried "everything" either but I am reasonably technical. I had done what you suggested to do before but I did both again.
Ethernet is yellow in the left side bar. In the right pane it's status says Connected but then below it says "Ethernet has a self-assigned IP address and will not be able to connect to the Internet."
I have tried the assist me menu and Network Status has Ethernet Green, Network settings Yellow, ISP Green, and Internet and Server Red and Failed for both. I have turned things off and on, checked cables, deleted all locations and tried restting them up but to no avail. I even disconnected everything and connected the mac directly into the cable modem itself and the thing still will not connect.
Thoughts???

How to make rolling plan at any point of time for 12 months using SOP/LTP?

Hi Gurus,
I am configuring an MTS scenario where the client desires that at any point of time, when he does planning, system should do a rolling plan. For example, let us say that we first do the planning in Jan for Jan to Dec. When he does the planning again in Feb, it should become a plan for Feb to Jan and so on. Is this possible in SOP/LTP? Please advise. Thanks.
Regards,
SB

Yes. This is normal for SOP, but what are looking to achieve using LTP? Is this rolling plan operative, or simulative?
