Big RAM and little RAM for Wallstreet

Hi,
I just received my 512MB (2 256MB chips) RAM for my PowerBook G3 Wallstreet. One of the chips is the normal size and the other one is much bigger, but it will still fit in perfectly, it's just alot wider, like double the other chip. My question is: Which chip goes in the bottom slot and which goes in the top?
Thanks

Well, I installed the modules and it seems to run great (recognizes all 512MB). If it starts to act weird I'll put the 192MB back in but it does seem to run just fine. And, as I said, the seller guarantee's that the RAM will work in this machine so If It causes my machine to stop running then they're responsible. Here's the actual description from the auction:
This auction is for 512MB KIT MADE OF 2PCS OF 256MB PC100 SO DIMMS. ONE WILL FIT IN THE UPPER SLOT AND ONE WILL FIT IN THE LOWER SLOT OF THE POWERBOOK G3 WALLSTREET/LOMBARD VERSIONS. These modules have been tested in our ISO 9001:2000 Government approved facility. Like all modules we sell, these modules have a LIFETIME WARRANTY and is GUARANTEED to be compatible with your Model.

Any need for conversation from big endian and little endian?

Hi,
I am planning to migrate an Oracle 9i Database on AIX 5.3 to Oracle 11g R2 Windows 2008, and have planned to use transportable tablespace. But prior to that task is the conversation required from big endian and little endian using RMAN?
Appreciate any suggestions, comments and hints
Thanks

Hi,
Check V$TRANSPORTABLE_PLATFORM, it shows the ending for each supported platform. Given the results on my 11g, I suspect that you'll have to convert the tablespaces...

Big Endian and Little Endian formats.

How can I read numbers from file in both big and little endian formats?

Not without reading them a byte at a time and doing
bit-shifting arithmetic yourself.I was hoping I will not get that kind of answer :) Well, if that's the only way,
can you tell me what kind of format is used in Java? Big or Little endian?

Good tracking speed, CHEAP, big, quality and reliable mouse for macbook pro

Hi mac people,
I need a mouse for this all purposes:
1)Reduce using the build in trackpad(to protect my built in trackpad)
2)Sometime I want casual gaming(Simcity,ps1 game, some other point and shoot game)
3)I 'm 183cm tall, so my hand is quite big, and I use my macbook pro as my primary pc, so need a all day use mouse(but I use my mac only about 3 hour a day).
4)as mentioned in title.
Thanks everyone for sharing advice!!!!!

As everyone's hands are different, I'd suggest going to any store with computer accessories and simply trying the feel of whatever brands of mice they sell.

Big Bang and GD65 (8D) PCI Loading

I am trying to compare the Big Bang and GD65 (8D) for a hypervisor.
My plan is to have two different video cards. One would require a x16 slot, the other would be OK in a x8. Now, I would like to determine how to best configure the drives and an extra NIC.
I am expecting 8 drives, 6 SSD and two HDD. 4 of the SDDs are for the host and 3 VMs, the other 2 are for buffering the 2 HDs. This four-set, it seems, have to be on the onboard SATA3 to use the hardware caching feature. For this, either board would seem to work. Then the other 4 SSDs can be serviced with a discrete 4 port SATA for the GD65 or a 2 port for the BB. The onboard SATA, I would guess, have dedicated PCI lanes. But when a card is added, do all the ports share the cards lane? So the item I am stuck on is whether the x8 slots for the GD65 will comprimise the SATA's through put for simultaneous access.
What would be a good setup?

HU16E,
Wow, that was an eye opener. Thank you for the details.
So the best I could hope for would be to use the two Intel ports for a RAID cache, and then have a controller card to pick up another two ports that can be configured as the Intel. Am I getting close?
1) Is there any advantages for putting the 2 HDDs and 2 SSD on the same card versus splitting them to on board and discrete card?
2) Is there slot arrangement trade-offs to coordinate the need for speed on the SATA3 ports and the one high end graphic controller?
I did not realize that caching the HDD was a RAID function. But I have not been able to locate an online description (RAID #). I have found a variety of proprietary solution white papers but no details.
Any idea what I can look for to learn more about this?

Difference between 1333 and 1600 mhz for 16Go RAM

Is there a big difference between a 1333 and 1600 mhz 16Go RAM and does my macbook pro 13" (2,9GHz intel core i7 - actually on 8Go RAM - 2011) support those?

RAM upgrade and other queries for 13" Macbook (Late 2006)

Hi everyone,
I have read many posts on these forums (very informative I must add) but I need your help in clarifying a few issues. I have a 13.3" white Macbook which I purchased in May 2007 - 2 GHz Core 2 Duo, 1 GB 667 MHz DDR2 SDRAM, 80 GB HDD. I plan on upgrading from my current OS 10.4.11 to 10.6 Snow Leopard in a few weeks. My issues:
1. Upgrade RAM to the max allotment. I read on Apple support (http://support.apple.com/kb/HT1651) that I can only go up to 2 GB RAM for my MB model. However various folks in this forum as well as 3rd party vendors dispute this for up to 3.3 GB RAM - via two 2 GB RAM memory. Can someone validate this? I plan to purchase memory from OWC.
2. My laptop fan is running more frequently than normal. Should I worry about this? I don't see any abnormal usage in Activity Monitor. Any thoughts?
3. I have clocked 312 battery recharge cycles on my MB battery. A couple of times the laptop shutdown when there was 15 mins charge remaining. Anyway the past few weeks I have kept the power cord plugged in since I don't move much. I read somewhere this bypasses the battery once the charge is complete. Is this true? Is there a battery recharge cycle count when its advisable to replace the battery?
Thanks in advance for the help guys. My MB has served me well and I really want to continue on this machine rather than doling out more $$ for a new MB.
Best,
Wal (SD)

I have about 20GB free space out of a total of 80 GB HD. At this moment I don't plan on increasing the HD space. But after installing OS 10.6, if the fan speed issue continues then I may invest in a new HD. My assumption is installing OS 1.6 will free up some space and I am hoping that will keep me comfortable.
Reg. my battery, yeah it has lasted for over 2.5 yrs. So I am happy about that. But I hear what you are saying. Perhaps I will get a new battery. Are there any longer lasting batteries introduced for the late '06 MB? A full charge lasts me about 3 hours - assuming I don't run any data or video intensive apps.
Thanks again for your advice!

Microphone and RAM for 2005 model Mac MINI??

My sister has a Mac MINE from Dec 2005:
Mac mini 1.42 512x1/ 80/
S/N: YM54701** <Edited by Host>
Since she is not at all computer-minded (but loves her MINI)- and I want to surprise her with a few upgrades when I visit her next week, what can I order (via the Apple Website?) or purchase to upgrade here MINI?
1. She wants to use SKYPE and has neither a microphone nor a videocamera for SKYPE. What is a good videocamera (with built-in Mic) that I can get? I have an iSight-- but I use it still so don't want to part with that!
2. Is it easy to upgrade her RAM to at least 1 gb? If so how and where to buy the RAM etc. She lives near Chattanooga, TN and I'll be at an APPLE STORE in Chicago on 24 June---
3. And not just for her MINI: What about FireWire adapter cables to be able to:
A. Take a FireWire 400 peripheral like an iSight and plug it into FW800 on a computer that only has FW800 (like a new MB13)?
B. Take a FW800 devise (like a Hard Drive) and plug it into a Mac with just a FW400 (like my MacBook from 2006)?
Thanks for any replies here!

Hello, Stephen Schulte2
1. I don't have a mini, but use this separate mic with good results:
http://store.apple.com/us/product/T6831LL/A
If you want a cable-free combined mic/webcam, Apple sells this BlueTooth model:
http://store.apple.com/us/product/TV520VC/A
For Skype known compatibly, you can search Skype's Store for Mac-compatible webcams:
http://shop.skype.com/webcams/ - most seem not to have integrated microphones
http://shop.skype.com/webcams/logitech-quickcam-communicate-deluxe.html has mic
2. "Easy" is a subjective term. This magazine shows how and says "Not Hard, But Not Easy".
http://www.macworld.com/article/42237/2005/01/macminiinside.html
You can even see video of it being done on this site:
http://www.youtube.com/watch?v=n1UmuWdNSrk
Whether you want to try it or have a technician do it is your choice.
If you do it yourself, Crucial RAM has a good reputation with many Mac users:
http://www.crucial.com/store/listmodel.aspx?pl=Mac%20mini&mfgr=Apple&cat=RAM
In my Macs, I usually use OWC RAM (and other expansion products.) The products I have bought from them are reliable and low-priced, and OWC offers as much support as you need:
http://eshop.macsales.com/shop/mac-mini/
Whatever you decide to do, I strongly suggest that any RAM you buy has a lifetime warranty.
3. A. You can use this cable that Apple sells:
http://store.apple.com/us/product/TP320LL/A
If you like, you can buy it locally or directly from Belkin:
http://catalog.belkin.com/IWCatProductPage.process?Product_Id=164598
3. B. That cable is bi-directional, so it does not matter which end is FW 400 or 800.
However, an adapter that connects 6pin FW400 to 9pin FW800 may be more convenient. You have a choice of many, but here are a couple of examples from which you can choose:

Bought ram for Macbook 4,1 and wont boot up

Hey guys i just bought some new ram to upgrade my macbook 2.1 Ghz Intel Core 2 Duo running Snow Leopard 10.6.8 and it says its the right ram for it but it doesnt boot up. the RAM i bought is 2GB PC5300/667Mhz DDR2. i bought 2 modules to equal 4GB and it doesnt boot. i tried one stick, both sticks, one new and one old, still nothing. the disk drive runs but thats all. So either i got bad ram or they labled it wrong? What can i do besides return it?

If you bought your RAM at a place that also sells PC RAM you may have gotten mislabelled RAM. PCs can handle different RAM speeds so they’ll often label higher speed RAM as a lower speed rather than make two different speeds of RAM. But Macs are much more picky. They require a RAM stick to be exactly 667mhz not 675mhz or 800mhz. The way to tell is to put one of your old RAM sticks in and it will force the new RAM to run at the correct speed.
This is from one review of PNY RAM:
"These modules are actually 800Mhz. PNY no longer makes or sells 667Mhz modules. Not all computers that require 667Mhz are compatible with 2 800Mhz modules. They refuse to down clock properly. This is especially true with a number of Core 2 Duo MacBooks. Spoke to PNY support, they flat out told me that yes, they sell 800Mhz modules in 667Mhz packaging. If you RMA a module that is 667Mhz (or supposed to be 667Mhz) they will replace it with an 800Mhz module as they no longer have any 667Mhz SODIMMs, not even for RMA replacement!"
These are good online stores for Mac compatible RAM
OWC 667Mhz RAM
http://eshop.macsales.com/shop/memory/MacBook/DDR2/ - They offer Mac tested RAM at very good prices.
Crucial Memory http://www.crucial.com/ - good place to buy RAM from all over the world. They also have an excellent memory selector that allows you to choose memory based on your computer's model
Data Memory Systems http://www.datamemorysystems.com/apple-memory.asp - another good, cheap place to buying RAM if you live in the U.S.

I bought a new 13 macbook pro with 4gb and would like to get aperture 3.4.3. Will it require too much ram for my computer? Thanks

I just bought a macbook pro 13" with 4gb and would like to get aperture on it. Will aperture require too much ram for my computer? Thanks for any support.

I just bought a macbook pro 13" with 4gb
I have been using Aperture on such a system, and it was o.k. with Snowleopard and moderately sized images. After I upgraded to Lion and started to user larger image files - 30 MB tiffs, I saw the occasional beachball spinning. You should be prepared to quit other applications that will hog the RAM (like Safari), when working with Aperture on Lion or Mt. Lion with only 4 GB. If you can, follow Frank Caggiano's recommendation and upgrade to 8GB. It will make a large difference.

Sounds just like what was happening with my Alum MB. I took it in and they replaced my battery. It seems to be ok now. I don't know what it is, but my battery was fine before 10.5.6 and the same timeframe of the firmware updates when they came out.
My battery health was jumping around but was fine before all of this happened. Unfortunately at 381 cycles I don't think you have much chance of getting the battery for free. Perhaps you can complain about the battery saying it was fine until 10.5.6 or whatever. Not sure when your computer was made, but perhaps you are eligible for this program: http://www.apple.com/support/macbook_macbookpro/batteryupdate/

CPU and RAM for TimesTen

I have test performance statistics for our java application (using oracle db) on a 4 X Quad-Core AMD Opteron™ 8360 SE cpu node with 64 GB RAM.
I am trying to collect performance statistics for TimesTen on a 2 X Dual Core Intel Xeon 5160 cpu node with 8 GB RAM.
My question is how does TimesTen treat processors. Is dual core considered as 2 cpu or single cpu?
So am I comparing performance - (2 X 2 = 4) TT vs (4 X 4 = 16) Oracle DB ?
Any suggestions on how should we compare the performance statistics obtained on the two machines ?

Please see my answers embedded below:
1. Under what conditions does TimesTen use multiple processors ?
CJ>> There are many background daemon components to TimesTen that are multi-threaded and may use multiple processors to some extent as required (main daemon, sub-daemons, replication agent, cache agent).
The main daemon is a very lightweight process that is purely supervisory in nature. It is not involved in database transatcion processing etc. and so its CPU usage is very low.
Each active datastore (database) has a dedicated managing sub-daemon. Again, this is not directly involved in transaction processing but it too has several threads. The checkpointer thread may use a lot of CPU while a checkpoint is occurring. The log flusher thread will use CPU in proportion to the intensity of write operations (primarily INSERT/UPDATE/DELETE) in the application workload (this thread is responsible or flushing the transaction log buffer to the log files on disk).
If replication, or AWT caching, is used the replication agent transmitter and/or receiver threads may use significant CPU depending on the replicated workload.
If Cache Connect is being used then the cache agent threads may use significant CPU when e.g. an AUTOREFRESH is in progress.
These ar all background activities and you do not have direct control over how many CPUs or how much CPU time is used by them. They will try and use what they need and the O/S will allocate them time based on available system resources.
Equally significant is the CPU power used to process application transactions. Each application process/thread that is executing via a separate connection will potentially be executing concurrently within TimesTen hence if you have 20 application threads (or processes) each with its own connection to a TimesTen datastore then TimesTen could potentially use up to 20 CPUs/cores concurrently. This is the key factor in your ability to control how many CPUs/cores TimesTen. The crucial things to understand here are:
1. In direct connection mode there is no dedicated TimesTen server process. All DBMS logic is encapsulated in the TimesTen library (libtten.so). All database query and transaction processing is actually executed in the context of the application thrad that makes the database call. Hence, as I mentioned, if there are 'n' concurrent application processes/threads each with a separate database connection then TimesTen can potentially use 'n' CPUs/cores concurrently. Essentially, # concurrent connections = max concurrent CPUs/coires.
2. In client server there is a dedicated server process or thread (depending on configuration) for each application connection and so again # concurrent connections = maximum number of concurrent CPUs / cores that will be used.
2. What techniques do I use to ensure maximum performance on this -
a. Machine with 2 cpu (each is a dual core processor) and 8 GB RAM.
CJ>> The number of physical CPUs (chips) is irrelevant. What matters is the number of cores. In this case 4. So, the system can concurrently execute up to 4 tasks. Anything more than 4 and tasks may have to wait for available CPU in order to execute. Since there are no blocking operations within TimesTen database processing then from a TimesTen perspective this machine can execute 4 application threads performing database access at maximum speed. Of course in reality CPU time is needed for the application, O/S, TT background processes etc. etc. so one would aim for fewer than 4 concurrent database processes. This assumes of cousre that there is no blocking at the application level either and that these processes or threads can therefore spend 100% of the available time executing. If the application blocks for any reason (e.g. waiting for the next 'request' from somewhere) then this introduces idle toime and so one can increase the number of concurrent application processes/threads to use up this idle time thereby increasing overall throughput.
b. Application using direct connection mode with weblogic Application server
CJ>> See my comments above. Generally one would use a connection pool and configure the number of connections to optimise performance (some experiments will be needed to arrive at the optimal value since it is very much dependant on the application workload and processing model).
c. All data is cached in TimesTen (using Cache Groups) for read intensive operations (There are few write operations as well but TT is mainly for the reads). Should the connections be 4 or 3 in this case ?
CJ>> If the volume of cache refrshes is low then you don't ned to 'reserve' much CPU for checkpointing logging and so you have all 4 cores available for application+database processing (plus O/S etc.). If the application is mostly using the database and not waiting for stuff outside the database then the optimal number of connections is probably in the range of 3-6. If the application does a lot of non-database work which may include waiting for things then the optimal number of connections will be much higher. Again, you need to experiment to find out what is optimal.
