DNS Advice Needed

Is it possible or advisable to let a standalone webserver hosting a handful of websites to be it's own dns server - in terms of holding the authoritative records for the domains hosted?
Thank you

DNS generally generates a trivial amount of traffic, so there's no technical reason, from a logistics standpoint.
However, in order to register any domain you have to have at least two authoritative servers for your zones. Therefore what you describe (hosting DNS and http) cannot be done on a single machine - at the very least you need a second machine somewhere for your DNS, even if it's your ISPs nameservers.

Advice needed on buying iphone as gift

I went to apple store, they do not want to sell iphone to me unless I sign AT&T 2 years plan. I thought AT&T has locked the phone and users must subscribe in order to use it. Why Apple store still not allow me to buy?
Please advice, if I want to buy online iphone for my brother, do I or my brother have obligation to sign out AT&T plan?
One more advice needed, I found the shipment takes weeks, do I have option to arrange for self-collection?
My brother birthday is coming soon, I need above advice urgently.
Thank you very much

I'm guessing English is not your first language. It's possible that you misunderstood them. Apple Store employees won't refuse to sell you an iPhone and you don't have to sign up for service in the store.
Well that's not entirely true.
Apple Stores have been instructed not to sell you an iPhone if any of the following is true:
You state that you will not be signing up with AT&T.
You do not have an ID from a US state, also indicating you will not be activating with AT&T
You do not have a credit card
For example, I've seen US Apple Store managers refuse to sell iPhones to European residents because of the AT&T lock-in.

Video intensive work on Mac Pro? Advice Needed

Hi everyone,
I've been originally saving up for a while now for an iMac 24" as it offers the best specification price wise. But now I leaning on the Mac Pro and therefore need some advice.
I know that there are alot of posts on advice - need to buy mac etc. so therfore I would really appreciate if I am afforded some help.
I am mostly going to do ALOT of video encoding (via handbrake) and I am looking for the best configuration available to achieve lowest waiting time.

I think you should go back and look at the other threads with advice, your budget. There is "ideal" and "affordable."
Will it pay for itself in 24 months so you can afford the next revision at that time?
Start with an 8-Core 3GHz.
Add a Port Multiplier controller and two drive cases, 5 drives each, nearly 400MB/sec RAID.
Throw in 8GB RAM.
Add in costs for software upgrades, two sets of backups, four internal 500GB drives.
Seagate has 750GB, as does WD. Hitachi has their $450 1000GB monster.
Give yourself time to build, test, and optimize your setup, and expect to change it over time as you learn more.
Can't afford that? then trim the 8-core. But Apple has shown how efficient next generation applications already are for video when it comes to 3GHz 8-core Mac Pro.

Had to have a rebuild of my laptop....advice needed!

Had to have a rebuild of my laptop....have now lost all my music from my itunes, but I can't transfer back on from my ipod. Also had to register my laptop (same) as another computers, so now no music showing as purchased, though I have. Also have hours of uploaded music from my own purchased, legitimate CDs, but won't transfer from ipod...it says it will erase. So very frustrated....thanks mr technician! PLEASE ....help, advice needed!

I believe that if you do a clean reinstall from your HD's recovery sector (D) or Recovery disks, the hard drive sector C is wiped clean. Everything goes, apps, data, address books, music, pix, viruses
Is that what you did?

Hi
That screen grab helps a lot. There’s a much easier way of doing what you’re doing.
Remove all your tabs and set the text in justified paragraphs.
I’ve typed in dummy text in the example I made below, but after “19.1” put in a space and put your blinking cursor after the space and before the ’N’ of ‘Notices'.
Then hold down the Command key and hit Backspace (on Mac at least - it’s the key between the Inverted commas/ apostrophe key and the return key).
The text will jump into place the way you want it to.
Hope that helps
Paul
PS You can set a tab, instead of using a space, in the description I gave above. So, after 19.1 or 19.2 or 19.185 etc etc insert a tab, then hit the Command Backspace after every paragraph number and they'll all line up exactly together. You'll find that editing text within the paragraphs
after you've set it will be LOADS easier this way.
You can put the tab anywhere you want it to be using 'Command-ShiftT' and putting a 'left align' tab just after the number. Just type the Command Backspace after the paragraph number and it'll work

Advice needed on move to in-house email. DNS and subdomain newbie.

Hi there.
One of my hats says IT Manager and I have a decision to make regarding about email services for a fast growing company.
At present my company uses MediaTemple to host our web and email, but are presently finding many limitations particularly in the flexibility of email accounts specific to various sub domains. An example of a feature we need (but {mt} can't provide) is separate accounts for [email protected] and [email protected] MediaTemple will only allow a single mailbox.
We desperately require this functionality which leads to my questions (as I'm easily perplexed by DNS and BIND):
1. Is it possible to modify a DNS zone file so that subdomains can exist for both our website (which will continue to be hosted with MediaTemple) and also exist locally for email on our in-house Xserve G5 running Mac OS X Server 10.4.7?
2. Does the Mail Server in 10.4 allow individual mailboxes for the same name under different subdomains.
Sorry for the dubious explanations. I barely understand the process itself, but I'm learning.
Thanks in advance,
Aaron in Australia.
Apple Xserve G5 Single 2GHz, 2GB/750GB Mac OS X (10.4.7)

The answers are yes and yes...
Managing a mail server, even on a Mac, can be complex and require a significant investment in time. If this decision is difficult, imagine trying to make ongoing config decisions, battle spammers, hackers and maintain 24/7 uptime for your users. Are you ready for that?
I would think that your current mail hosting company can host mail for a subdomain, but probably not within the same hosting account. The level 1 people you are talking with may not have a clue. You may need a hosting account for each subdomain (with user accounts in each hosting account). If this email hosting provider doesn't support subdomains, then consider others (really any should). You'll need to make some DNS adjustments, something the hosting company can direct you on.

OS X Server setup advice needed for small business

I work as audio engineer at a recording studio. I'm an experienced Mac user, but I don't have Mac Server experience. I'm my company's default IT guy. Our office consists of four people, currently using PCs, but we are changing to a Mac-based office: each person will get an iMac, and we'll also get a Mac Mini with OS X Server. And a Time Capsule for both the Apple router and Time Machine backups. The machines will be connected with ethernet for Gigabit networking.
The server will be used primarily for two things:
1. Server-based scheduling/contact database program that each user will log-in to for access
2. Hard drive for storing audio files that will be delivered to clients (currently FTP delivery)
I'm learning about OS X Server services - there's some great You Tube tutorials by Todd Olthoff http://www.youtube.com/user/tolthoff.
The office users currently run their computers as independent PC's with all files stored on their local machines. The network lets them share files, as well as share two printers. Note that my plan is for each office user to continue to store their files locally on the iMacs, not on the server.
I'm trying to decide how much of OS X services I can take advantage of.
I have some specific questions I'm hoping to get some advice on. These questions came up after viewing Todd's tutorials:
1. Do I need Open Directory
I think I do, in order to create local network users. Is this a given for me?
2. We do not have a static IP address. Do I need to establish DNS services?
3. Do I need a verified SSL Certificate?
This is what I have for starters. Any additional advice is welcome!

2. Hard drive for storing audio files that will be delivered to clients (currently FTP delivery)
Remember that ftp is wildly insecure, and a very large ftp credentials dump — reportedly including credentials from the New York Times and some other users — was just posted. ftp is a massive pain in the rump around modern networks; the protocol design predates the uniquitious use of firewalls in modern networks.
Read: I'm not a fan of ftp.
Use sftp or VPNs where you can.
1. Do I need Open Directory
I think I do, in order to create local network users. Is this a given for me?
If you want to start using the same login across different Macs in your office, then you want OD.
2. We do not have a static IP address. Do I need to establish DNS services?
You need local DNS services on your LAN (probably established via OS X Server), and you'll need external DNS to allow external folks to get to your file servers, and you'll need static IP from your ISP. If you get to using your own mail, you'll need a proper DNS configuration — forward and reverse DNS translations and the MX record must all match — for that.
3. Do I need a verified SSL Certificate?
Unless you're serving HTTPS or such, no. You don't even need a certificate and can use a self-signed one, if you're small and not serving much publicly from this server, and not doing something like ecommerce, and if whatever you're doing isn't a target for those that want to spoof or crack web sites; if you're not more of a target than most of the rest of us on the 'net.
Any additional advice is welcome!
I'd probably look to add a VPN-capable firewall router box here, and would use the Time Capsule as a so-called Access Point on the network — not as a NAT-capable gateway router. This if you don't already have a router of some sort. Time Capsule makes a nice home router or low-end SOHO router, but it's fairly limited in its features.
You absolutely need LAN-local DNS, and you need that correct and working and tested before you enable other services on your network.
I'd recommend using a real and registered domain on your internal network, and using a separate (and registered) domain outside your network. You can get away with using a subdomain inside, but that means more typing as it's just longer. I'd avoid a made-up domain, as ICANN is adding all sorts of new domains. I'd also avoid squatting on a domain, and never use the .local top-level domain as your own DNS domain. Leave .local to Bonjour only.

Multiple Xserve config- help/advice needed...

We have just purchased a second xserve (quadcore) to go along with our current xserve (G5 dual-core). We run FTP, web(wikis, blogs, etc that use the LDAP for authentication), LDAP, Open Directory, softwareupdate, DNS, NetInstall (occasionally) and AFP services.
I would like to share the services across the two servers- using the new, more powerful machine to host the home directories, AFP, FTP, etc; and the older machine to handle web, etc. My concern is that I would like to have both use the same LDAP so that I only have to enter in users once, and so that everyone can access their files via FTP at one IP.
Is this even the best way to be thinking about implementing this? Will assigning one server as the OD master, and the other as the OD replica provide both servers with the same LDAP directory? I have clearly never done this before, and I am very excited to be able to use two servers to increase the efficiency. Thanks for any help/advice.

Hi
+Is this even the best way to be thinking about implementing this?+
Yes
+Will assigning one server as the OD master, and the other as the OD replica provide both servers with the same LDAP directory?+
Yes
I've done this myself many times. The relevant Admin Manuals do have enough information outlining what needs to be done:
http://www.apple.com/server/resources/
Steve's link is something you should definitely look at. There are some minor differences but nothing to get worried about. Both Servers have to be exactly the same OS and SSH needs to be enabled.

Server has gone wobbly - advice needed.

I'm hoping the experts here can point me in the right direction.
I have taken over a position as IT Manager of an all-mac business (~20 users) using a co-located XServer that is currently running 10.5.7. I'm trying to work with the hosting company to upgrade to 10.6.1 (or .2) in the next couple of weeks. (All clients save 3 are on SL.)
The person whose position I've taken over is no longer available and while I am extremely competent with Mac (20+ years) I am new to the server side of things. I'm very comfortable in Terminal and have a beginners knowledge of Unix/Linnux.
To the point: My server has in the last few weeks become extremely unstable and upon restart can take 40+ mins. to restart during which time, of course, I cannot ssh or screenshare. I have made no changes to the settings save for two DNS updates (IP address changes for www and ftp). The old IT manager has updated security certificates and installed a self-signed. Our RAID controller reports no problems, neither does the Server Monitor.
I'm hoping the upgrade to 6.1 will help stabilise, as I have no idea where to start investigating. Prior to this we had uptime of well over 45 days. Now I can't seem to go more than 5.
I know I haven't even begun to give you the information you need to help me solve this issue but I'm wondering - are there any books any of you would recommend that would help me really start to get a handle on the intricacies of maintaining this server. I have all the apple docs and have read the majority of all of them, but since I don't know where to start looking, I'm finding the doco little help.
Any assistance or advice offered will be greatly appreciated. Thanks!

IMHO, the problem with documentation is twofold:
1) it's copious - there are reams and reams of documentation on Mac OS X Server - each service has its own volume - Open Directory, File Sharing, DNS, VPN, Mail, etc., etc.
2) it's all based on theory - it all says how it should work but rarely covers what to do when things fail.
The first problem means it can take a while unless you're really focussed on one issue at a time and can find the right piece of documentation. The second problem is only really solved with time and experience.
In this case I think your best start is to review the server logs for any clues. Mac OS X Server is pretty good about logging error conditions, so look specifically for any log events that occur around the time the server goes down, as well as the startup logs which can add additional information.
I wouldn't recommend upgrading to Snow Leopard until you know what the issue is. You run the risk of compounding the problem, and migration of data can take time even when things are good.

Multiple device syncing advice needed and appreciated.

Hey everyone, happy holidays to everyone
I need some advice from you Apple lovers out there if you can spend some time replying. Thanks alot in advanced
My devices and current status
13" Macbook Pro with 8gig RAM with lion OS - Mosty used for word processing, DJing, low Internet usage now that i have Ipad, photo management, DVD ripping etc etc - i use this as my main device to organise emails and i purchase most apps, music and films on this device too
Ipad2 - Mostly for media content, web browsing, Youtube, playing games, FB, watching films. I use this device for fun not functionality or work related things
Iphone 4 - Usual phone usage, I use my phone as my main device for iCal, contacts, checking emails/messages on the move
2GB time capsule - brand new in the box as yet unused
Generally speaking i get confused or change my mind frequently about what to sync to which device, i started off using icloud but then things got confusing and i had things real messed up, multiple same contacts, apps on differnet device, differnet music on all 3 devices so now for the moment i think of my Macbook as the main device with both my iphone and ipad backed up to the Macbook. I then back up all of this on a regular 500g external Hard Drive.
So my questions are as follows
1. Can and should i use icloud to back up my devices and if so how should i do this effectivly
2. What syncing procedure would suit me best
3. How should i integrate Timecapsule to my devices
Any other suggestions would really be apreciated
Thanks again

The second part puzzles me - excuse me (but i honestly don't know) do both units give off a wifi signal of roughly equal 'amounts'?
Yes. Since both are connected by "Ethernet" each base station is its own wireless network and you have a few options on how best to configure them.
One of those options is to give both wireless networks the same Network Name (or SSID) so that you can, for example, "walk" a laptop from one to the other and stay connected. This is known as a roaming network.
If this is something that you don't desire or have a requirement for, then leaving them as two separate wireless networks would work just as well.
So what i am asking - i guess - is can i increase the distance the wifi signal reaches of the second unit (the time capsule - that is wired to the airport extreme)
To extend the wireless range of the Time Capsule (TC) you would need another 802.11n AirPort, like the AirPort Express Base Station (AXn). This should get a stronger signal out to the garden. Of course, it would really depend on the distance from the TC to where you would like to place the AXn to get the best results.
Let me know if you need help configuring the base stations.

I have constant K8N Neo2 problems advice needed. (long) Update

I need some advice on what my problem might be and if I need to RMA the motherboard or power supply.
I have a new Athlon 64 3500+ processor, MSI K8N Neo2 Platinum BIOS v1.3 motherboard, with 2 512MB DIMMs of Corsair Value Select Memory. I have had and am still having a series of crashes and lock-ups I will list below. FULL SYSTEM SPECS BELOW AT BOTTOM.
I initially installed the motherboard with a SINGLE 120GB hard drive from the old machine and the installed the memory in memory slots 1 & 2 to try dual channel memory mode. I then formatted the C partition and did a clean install of Windows XP Professional with SP2, installed the MSI drivers on the installation CD that came with the motherboard (Nvidia nForce3 Version 5.03 System Drivers, Realtek gigabit ethernet driver, Realtek AC97 audio driver) & the GeForce v66.93 video driver. I then got my first blue screen "MACHINE_CHECK_EXCEPTION" crash, I ignored this crash and rebooted. I shortly got a black screen crash which I also ignored.
I then installed a new 200GB hard drive and a old 120GB so I could transfer the data from the old 120GB to the new 200GB drive. The data transfer went fine. As I was preparing to install some applications I then got my second blue screen "MACHINE_CHECK_EXCEPTION" crash. Suspecting the Corsair Value Select Memory could not handle dual channel I ran Memtest-86 for 2 passes and got NO errors with the memory in dual channel mode, so I left it.
With my data backed up on the 200GB new drive I removed the new 200GB and the second 120GB hard did another clean install of Windows XP Professional with SP2, this time with Nvidia’s nForce3 Version 5.10 system drivers, the Realtek gigabit ethernet driver and Realtek AC97 audio driver from the motherboard installation CD & the GeForce v66.93 video driver. I downloaded the latest version of Core Center and installed it and got it working. CPU temperatures were showing a low of around 29C, average of about 44C, and spikes at full loads of about 55-57C. I then ran Ghost to back up the boot partition. I installed all my applications, reinstalled the 200GB and 120 GB hard drives moved some data around with no crashes.
I then installed Rome Total War and played for about 2 hours and had one black screen crash after the reboot played for 4 more hours with no problems so I shut down and went to bed.
In the morning I got up started the computer let it run for awhile the CPU temperatures were in the low 30Cs to low 40Cs I tried to copy some files from the D partition to desktop and the screen freezes I waited about 5 min. with no change and no drive light activity so I hit the reset button. Upon reboot I got a ‘no system disk found” error, I went into the BIOS and checked the drive set-ups and boot priority, everything was correct. I tried for a half hour to get the system to boot with on luck. I used the Ghost to restore the partition image I had made earlier and still no boot. I finally decided to reinstall XP again put in the installation CD and when I got to the screen where you decide where to install Windows I changed my mind quit and bingo the machine boots into the restored Ghost partition???? I started to reinstall my applications got one more blue screen"MACHINE_CHECK_EXCEPTION" crash and another screen freeze that I had to reset.
So I decided to start from real scratch I removed the new 200GB and the second 120GB hard drive ran Killdisk on the boot drive, made a new clean 20GB C partition and did another clean install of Windows XP Professional with SP2, this time with Nvidia’s nForce3 Version 5.10 system drivers, the Realtek gigabit ethernet driver and Realtek AC97 audio driver from the motherboard installation CD & the GeForce v66.93 video driver. I installed the latest version of Core Center and installed it and got it working. CPU temps were as before.
I tested the memory with Memtest-86 again 2 passes no errors. Just in case I then moved one of the memory DIMMs to memory slot 3 out of dual channel mode and to a slower speed and ran Memtest-86 for about 20 hours with 21 passes with no memory errors, so I think memory can be ruled out as the problem.
Next I installed my applications I got one screen freeze that I had to reset. I reinstalled the other 200GB and 120GB hard drives. After I got all my applications install and Ghosted the boot partition. I have had one more one screen freeze that I had to reset.
I have a problem I simply cannot figure out. The memory is obliviously fine. While I have seen CPU temperatures spikes as high as 57C the CPU temps as reported by Core Center averages in the high 30Cs or low 40Cs and most of crashes/lock-ups don’t seem to occur during high CPU load/temp. The power supply might be a little light for the system but many of the crashes have occurred with only one hard drive in the system. The fact after one for the lock-ups the system would not boot for awhile and then magically just booted gives me concern there might be a motherboard problem.
Any solution ideas would be appreciated. Should I RMA the power supply, the motherboard, or both.

Great isn't it (although not without the occasional crash)
Would you say it's better but not there yet ? or the same ?
I thought the same as Ibn Quote
Your PS unit is a little weak for that much hardware, but I doubt thats your problem as well
re your PSU, given youv'e got a less hungry Graphic Card, thought it was at worse marginal, have seen worse.
To investigate further it may be worth diconnecting one of your HD, maybe the 200gb for a time.
It's a small thing but it may be slightly better to have both your maxtors together on IDE channel 1, given their identical.

Mid 2010 MacBook Pro - Logic Board Failure - Advice Needed

Hello all,
I could really use some advice.
I have a MacBook Pro that I bought through the Apple Online Store roughly around September of 2010. A couple of weeks after buying it I had to take it to the Apple Store in London's White City due to a keyboard backlight issue. About a week later I collected the MBP and the following day had to take it back as the technician that worked on it had not tightened the display brackets up leaving it a bit floppy.
Now I have serious issues with it. Recently the MacBook has been suffering from freezing up, booting issues and the display randomly shutting off (going black, no pixelating or anything) to the point the machine has become unusable. 2 days ago I took the MBP along to an appointment at the Genius Bar at London's Regent Street Apple Store, I also took along a copy of an Apple knowledge base article regarding this very issue. The knowledge base suggests that on any OS below Mountain Lion a software update is required, for ML or Mavericks an appointment with a service agent is required. During the appointment the Mac Genius suggested it may be a software issue, they would wipe the system and re-install Mavericks then test the machine, I told him I had done this a few days earlier but I guess they have to follow process. He then went on to suggest the display may be faulty, I told him I had no reason to suspect that was the case and moved the screen forwards and backwards at varying speeds without a glimmer of a flicker. At this point after reading about this issue on various forums prior to the appointment I felt that the guy was trying to imply anything maybe at fault but deliberately steering clear of suggesting the logic board, this is just my gut feeling however and i'm perfectly capable of being wrong but I do not feel I am! Anyhow I then proceeded to demonstrate the issue whilst the machine was on, warmed up and right in front of him. I gently and slightly lifted the front left corner of the machine a little way off of the counter, just enough to obviously flex the logic board by a minuscule amount and immediately the display went into a frenzy of going off and on.
So I left the MBP with them for the guys to do their thing. Today I received the following email:
"We have attempted to repair your machine by erasing all the data off your machine and reinstalling the latest operating system, Mavericks. This has not resolved the issue of the screen going black when in use. The issue has occurred again for a very short and brief few times once the machine had fully turned on and after testing the issue did not appear again.
I'm sure the issue will more likely occur again, to repair the machine we would need to replace a part known as the main logic board. This repair is very expensive and will come roughly to £418.80."
£418.80 GBP, that's pretty much 25% of the original purchase price of the machine new, a Premium 'Pro' labelled machine just 3 years old at that. I cannot possibly afford to pay for the repair. I really despair.
This MBP has done no work hard enough for it to get stressed. It is used for some web surfing, online shopping, email, online flash based games but mostly for my kids homework. It has spent it's entire life on a table in our living room with the exception of it's Genius Bar trips.
I love Apple products, it's why as a family we own so many off them. Too many to list on a public forum as I don't want would be burglars inviting themselves around sometime. This issue has tainted my perception of both Apple and it's products. Not so much because of the fault, machines become faulty. No because it's a premium machine that cost me £2100 new and is little more than a paperweight at present just 3 years down the line. Some part of me if i'm honest was wishing but more than that expecting a company like Apple to say along the lines of "This has happened, it shouldn't have and will be repaired at no charge". There are many people suffering this kind of problem with this model and the existence of the knowledge base article must mean Apple knows it too. Just 3 years, £300 PCs last longer than that i'm sure. It does seem to be a very short lifespan for such a high end machine.
My apologies for droning on but I can neither afford the repair or do without the computer, my son is in his final GCSE year at school and my daughter in her pre GCSE year so a computer is critical for school homework research etc. I just do not know how to move forward, I haven't even picked the machine up yet!
This isn't a stomping Apple, one man crusade. I just need my MacBook fixed.
If anyone has had this problem and had it satisfactory resolved, knows who to speak to that may help resolve the issue please let me know.
Any other advice will be more than welcome.

Ive repaired 1000s of laptops over the years (translate: diagnose and replace parts).
Its not that old, Ive owned 100s of laptops (most were free) ....some I still have are nearly 13 years old and still perfect, ....some extremely expensive ones died in under a year.
other than becoming obsolete at some point, there isnt really any "will spoil on" data like Milk for solid state computer parts, ....alas.
You can have a $5000 laptop die in 4 months, and a junker one keep kicking after 10 years.... Ive seen that firsthand countless times.
Common logic dictates that "very expensive = long life" in computers,..... but all the repair people will tell you just the opposite.
I know you have a gripe, I get that all too well honestly .

How many DNS record need to create in Internal & external DNS server for exchange?

Hi friends,
I recently installed Exchange Server 2010 in my organization for testing purpose and I've register a pubic ip too for exchange server on godaddy.com. How many
internal & External DNS records reqired to configure on external & Internal dns server so my all feature like Auto-discover, Activ -sync,& webmail start working perfectly.
It's my first time configuring exchange for a organization.
Thanks & Regards,
Pradeep Chaugule

Hi,
Just as what ManU Philip said, you need to create
Autodiscovery.domaincom and mail.domain.com for external dns server.
Generally, you configure your Exchange Servers as DNS clients of your internal DNS server.

Advice needed regarding Database design practice

OK, here is my situation. I've started working for a company about 6 months ago. I'm a .NET developer with 12+ years of experience. Most of my experience with databases is with SQL Server. Recently I've discovered an design change with our Oracle database that our DBA made that I completely disagree with.
We had a single Event table that holds records that pertain to all HTTP traffic on a network as HTTP Usage Event. There are multiple hardware units called 'Sensors' that monitor the network and report these HTTP events to the database. At some point not long ago, the table was holding just over a million records. Performance was suffering so the DBA decided to make a change to the database to accommodate. The change she made was to create a separate Event table for each sensor. Each sensor has an integer value as a unique identifier, so our database went from having a single Event table to now having Event_100, Event_101, Event_102, etc...
So, we now have over 200 Event tables in our database. Anytime a sensor is added to the system, we need to add another table (actually two as there is a 2nd table that was duplicated in this same fashion).
How do I present this to my boss and to the DBA in a way that I don't embarrass my boss (he approved the change) and without pissing off the DBA? I can't imagine that the table couldn't have been optimized as it was to take care of the issues with performance without so dramatic a change.
Any advice would be greatly appreciated.

There is a job to purge old data. Events are kept for 3 months. These jobs were actually part of the problem, as well as removing sensors from the system. In either of these cases, the deletion of the data (more so with the removal of a Sensor i.e. DELETE FROM EVENT WHERE SENSORID = X, was taking too long).
I'm surprised that there have been people agreeing to this design. So, now we have 208 sensors, so 208 Event tables and another table named DATA_HASH duplicated 208 times. There may be a time when our database will be handling data from over 1,000 sensor units. Maybe even double that. Can anyone argue that having 2,000 event tables is the way to go? What if we need to add a new field to the table? Do that 2000 times?
I've been looking at bit more at the data today. I found some event tables haven't got any data (0 rows) while others range in row counts of 2 million up to as much as 30 million? I've talked to SQL DBA's and they all think that Oracle should be able to handle billions of rows in a table.
Also, just out of curiosity, I looked up the max size for a table in Oracle 10. I know the number of rows isn't the determining factor for this, but size of the data. I was astounded to find out the max size for data storage for a single table. 127 TB (yeah, tera bytes). Based on this size, it seems our data could be handled by 1 table, but then maybe I'm wrong.
