Need expert opinion

hi experts,
we are going to setup Oracle RAC of 4 nodes using IBM P-series servers with IBM SAN DS-4800. the space is minimum 3 TB. now what I want is to implement ASM Volumes and OCFS for Database Files, FlashBack and OCR, Voting Disk respectively. now what I'm planning is to make
(ASM) 2 Volumes with Normal Redundancy for Database Files and
(ASM) 1 Volume for FlashBack with External Redundancy and
(OCFS) 1 Volume for OCR and Voting Disk with External Redundancy.
Now plz guide me whether you think its an optimal solution or not? I would appreciate all kind of suggestions and recomendations.

I would insist on these disks being striped and mirrored on the storage array/network and be given to the o/s as the largest possible LUNs.
On the o/s side, I would partition one of these into 2 partitions. One for OCFS2. The remaining partition for ASM. The other LUNs all ASM volumes.
The OCFS partition need not be large. The voting and registry files are small. But having a clustered file system is very useful (think Oracle database directories being available on all nodes, common set of scripts and files available on all nodes, etc).
In ASM, the LUN disks (raw devices or multipath devices if not using the ASMLib kernel module) will be defined as one or more disk groups with external redundancy.
I would not bother managing the LUNs as separate disk groups and trying to spread and balance I/O by creating some datafile one one disk group and others on the other disk groups on the RDBMS side. ASM does all that for you.
Also, actual I/O bandwidth is a primary factor of the HBAs - and the size and number of I/O pipes to the storage device. It does not make sense wanting to manage those aspects at RDBMS level.

Need experts opinion... Should I use smcFanControl?

I've recently purchased a MacBook Pro 13" with an i7 processor and 8GB of RAM and have been watching flash player videos on the internet and playing pretty basic games that use programs such as Java and have experienced temps topping at 101 degrees Celsius. I'm not an expert with laptops, but I have done a TON and I mean HOURS of reading online for the past several days and have read posts where people have encouraged the use of smcFanControl when needed and read the opposite side where people say to not mess with it and trust in Apple's engineering. From my basic understanding, it seems like more acceptable temperatures should be around 80-90 degrees Celsius for these tasks. Am I correct in this thinking to protect my laptop? This is my 1st laptop and I want to make sure I can make it last as long as possible, so what's the truth? Should I use smcFanControl just when I plan to play games or watch flash player videos? If you've used smcFanControl for years, please speak up along with anyone else who knows a lot on this issue. Thanks!!

hi ,

<FIX>

Now first i have to parse this xml ..then my java program is going to accept value from user ..and depending on user specified value i've to use either ATO or FIX fields...e.g if user value is 35 then my program should use fields within ATO node.
You will read the XML structure into some kind of memory model. When the user supplies a value you will search for a matching value (likely from a collection such as a map or list) and return the value in that object that you locate.
what should be done for this ..
See above.
and what if i change values in my xml file..will i have to restart my application to load xml again ?
If you change the file on the filesystem, you should simply be able to re-parse the XML file and update your in-memory model. If you instead update your in memory-model, you can serialize the model back to XML on the filesystem. Neither needs to necessarily have anything to do with application start-up (other than the fact that you would normally read in the XML model then, but updating is a separate concern, as would re-reading it).

Need Expert Opinion on 3D LED TVs

Hi, I'm a movie critic for a local magazine in the city. My new assignment is to critique about 50 movies in a two week period, all 3D movies. I've heard about the amount of strain on the eyes from long sessions. Are there any 3D LED TV's that cause little to no strain on the eyes?

theres a bit of misinformation here. In the traditional sense, yes, the Cinema 3D TV's are technically Full HD (1080p resolution), but you are still only seeing 540 lines of resolution for each eye. Yes, all of the pixels are active simultaneously, but the image you are seeing for each eye doesn't even meet "Enhanced Definition" standards, let alone HD standards. Active shutter 3D, on the other hand, Outputs 1080p Resolution to each eye. Active shutter technology gives a significant improvement to the image detail.
The only benefit of passive shutter 3D technology is the cost of the glasses. When compared to a Plasma TV however, which are not only cheaper, but provide better 3d performance (Active Shutter, less crosstalk, no motion issues, better PQ, higher resolution, etc.), you'll find that it's a much better deal. You'll probably even save money, and end up with greater performance for both 2D and 3D.
As a movie critic, I assume you need to be giving people the best/most accurate review possible. This means moving up to a larger size television (55" at the very smallest), and picking up a set with at least decent quality. I've watched 3D on 90% of the 2012 3D televisions on the market, and you'll find that some of it comes down to personal preference and changing settings within the television to adjust comfort level. When it comes to 3D, larger is better, and you will find your self wishing you picked up a larger TV. (With a 65VT30, I still find myself edging the couch much closer to the TV)
Quick question, are these reviews focused more on the movie content? or picture quality/3D quality? The answer to those questions will give the best indication on which TV is the best option for you.
Out of all of the TV's I've watched, I've found the Panasonic plasma TV's to have the least amount of fatigue (aside from the inferior passive shutter LG LED TV's). You can reduce fatigue even further by making adjustments to the 3D depth. Active shutter LED TV's will be slightly more fatiguing due to flicker and motion judder (with the exception of top of the line models from Samsung or Sony). Samsung plasmas are slightly more fatiguing than the panasonics, but the difference is subtle. My TV recommendation would be a Panasonic 60ST30, which has one of the best price/performance ratios of any 2012 TV. If you insist on getting an LED TV, I would recommend a UN60D8000, which will give you the best 3D performance (on par with or greater than plasma 3D performance), but you'll find yourself in a much higher price bracket (money better spent towards a PN64D8000 or 65GT30/VT30 plasma TV).
Again, some of what I've said is subjective, but i've given my opinion. If you can narrow it down to a couple of models, then head into your local best buy and pick your favorite.

I REALLY need expert opinion with my mac/fcp shopping list!

I work in TV and I'm buying an hdr sr12 so that i can work on my own projects, move my skills along etc...
To edit the footage I'm thinking to buy a 15" 1st generation macbook pro and fcp studio 2??? is this what i need? could i get away with spending less and getting different versions of either? - Any advice is a huge help. It's taken me weeks to get this far.
Cheers Dan

will i get away with a powerbook g4 and an older version of fcp to edit the hd footage?
It depends on the flavor of HD and which version of FCP you have. For example, FCP HD (version 4.5) only works with one flavor of HD: DVCPro HD. If you're working with HDV, you'll need FCP 5 or higher. For AVCHD, you'll need FCP 6 and an IntelMac. Other HD incarnations have their own requirements.

JDK1.3 and Netmeeting Not compatible?? Need expert opinion! Thanks!! :)

Hi Everyone!! :)
I have researched this topic and have not been able to find a decent answer yet. So I'm asking the experts now!! :)
I have a java application written and compiled in jdk1.3. When a user runs this application remotely through netmeeting, they only get an intial gray frame, but nothing shows up on it. The menus and other GUI stuff ARE usuable, just not visible to the user. NOTE- if watching from the computer where the application is actually run from, everything initializes just fine. I've read that this is a problem in general with jdk1.3. Has anyone had any success with jdk1.4 and Netmeeting? Or does anyone know of a way to get to force jdk1.3 to work with netmeeting?? The later of the two would be preferable due to compatiblity issues with other programs and jdk1.4...
If I find something useful myself, I'll post it, but right now I've hit a dead end. ANY ideas would be great! ;)
Thank You!!
Katie

Sounds odd...I'm sure that the same technology used in Netmeeting was used in Remote client access...and I can run my applets thru Remove access with no problems. I usually find problems like this are related to a graphics problem...like colors too high, resolution too high, or the video acceleration is too high.

Need Expert Opinion on what 2.0 Card to buy

I need a recommendation for a 2.0 USB Internal Card for my PowerMac G4 Dual 800, Tiger.
When you get down to the details of some manuals of some of these cards they don't support Mac/Tiger. i.e. Belkin 5 Port
I would like a card with more than 2 ports.
Thank You, Tom

I'll second that recommendation. The Belkin 5-port PCI card has been in use on my desktop box for about a year now. No problems with Windows, and Linux is quite happy with it too.
One thing to note: the 5 ports are not all accessible from the outside. This is actually 4 ports on the outside, with one on the inside of the computer. I have a drive mounted memory card reader that uses the internal USB port on this card, but you can get drive mounted USB hubs that use it too.

Need experts opinion on AS2 troubleshooting

In two separate instances with partners i configured File sender channel with AS2 reciever.
Getting three different errors as below:
First customer : I get "Delivered" but in Technical message "Validated-synchronous;Negative MDN Reason: MDN Disposition Modifier-Extension is error-Decryption failed"
Second customer : I get "Delivering" and later time out.
What can be different causes for these two types of errors. ?
Regards.
Aditya Sharma.

Hi Aditya,
A negative MDN does not necessarily mean a technical problem. Check with your AS2 partner why your message has been rejected.
A time out means that you cannot reach you AS2 partner on time.
Check your connection to that partner and try again. Perhaps a simple ping from the SAP PI machine could already give you an idea.
Kind regards,
Dimitri

I need your expert opinion on how to create a map with multiple conditions.

Hello.
I need your expert opinion on how to create a map with multiple conditions.
I have a procedure (which i cannot import or re-create in OWB due to the bug), so i am trying to create a map instead :-(
How can i create a cursors within the map?
My function creates table and cursor.
Then it will have to check for duplicates in the tables (the one created and another table) - the criteria for finding duplicates is a number of fields.I then need to place few different conditions (if some attributes are not available) and it has to load cursor based on this conditions. The next step is to fetch the data into the cursor based on what attributes are missing.
The next thing it will do is insert the data into table (if record doesn't exist), output the error in separate table is record is corrupted, or update the record with changed information.
In short i need to re-create match / merge but with conditions, iterations etc 'built into' it.
I can read up on available functions - it's just what would be the best options? and what would be the best approach to do so?
In my function i use %rowtype - but cannot use it in owb - so what would be the alternative? i don't really want to create a lot of variables and then have a nightmare of maintaing it. are there any tips regarding this?
having looked through Oracle dedupe - it's not really what i need because it is just DISTINCT.
I would appreciate any help / advise on this.
Thank you very much

thanks a lot for your reply - i will look into this option :-)
it is a bit more complicated now as i have to re-create the match / merge and then somehow 'tweak' it to achieve the result i need.
At the moment i am looking to breakdown the package into smaller chunks 'functions' and try creating the map that way.
Anyway, thank you very much for your suggestion.

Need the opinion of experts: N85 with Bluetooth pr...

Really need the opinion of experts on this one.
My N85 was swapped after the complaint that the Music Library Menu opened automatically after pairing with bluetooth of the car (permanent failure). Another complaint was that video recording was defective (intermittent failure). Also, Nokia detected great consumption of battery.
My question is: the swap came back the same relating to the bluetooth problem.. Is this a case of bad repair or a case of low knowledge...? I'm wondering if the Music Library Menu is to open when pairing with car bluetooth (strangely)....

The Dell Precision 380 has 3 PCIe slots: a x16 (for video cards), a x1,
and a x4. I'm sure there are other PCs on the market with
multiple PCIe slots.
Alternatively, the PCIe-8362 has TWO cabled PCI Express links. So
you only need one slot in your host PC. This may not be the best
solution, however, if bandwidth is your primary concern. With one
8362 connected to two chassis, the total maximum throughput is 160
MB/s. With two 8361s (each connected to a different chassis), the
total maximum throughput is 220 MB/s (110 MB/s on each).
Finally, keep in mind that the PXI chassis in your system are still
running at PCI speeds (132 MB/s). Plus, this bandwidth is shared
across all devices in the system. So the MXI Express connection
to the chassis may not be the bottleneck in the system.
Good luck!

SQLJ Expert Opinion

Hello,
I need to have some expert opinion the code where I have used SQLJ, whether it is alright or anything to be changed. I use this to fetch results from a remote table and populate in local table in every half an hour.
Thanks and below is my code.
***Code**
public static void getDataLMStation()
try {
Oracle.connect("jdbc:oracle:thin:@xxx:1580:xx","xx","abc",true);
#sql iterator SeatCursor(String LOCATION, String PRODUCT_TYPE,String STOCK_POSITION, Timestamp READ_DATE);
SeatCursor sc;
#sql sc = { select LOCATION,PRODUCT_TYPE,STOCK_POSITION,READ_DATE from PORTAL_STOCK@abc};
System.out.println("sql "+sc);
while (sc .next())
#sql { insert into PORTAL_LMINVENTORY(LOCATION,PRODUCT_TYPE,STOCK,DT) values(:(sc.LOCATION()), :(sc.PRODUCT_TYPE()),:(sc.STOCK_POSITION()),:(sc.READ_DATE())) };
} sc.close();
Oracle.close();

It looks correct however, i am not sure you can use the same execution context for retrieving data from the iterator and processing the INSERT.
Fwiw, i covered SQLJ 10g in my just released book http://www.amazon.com/gp/product/1555583296/

Need expertise opinion on ADF custom BackEnd implementation

Hi all,
Jdeveloepr version: Studio Edition Version 11.1.1.5.0.
I am working on an ADF application and trying to go with the following implementations which are currently working fine while unit testing (me alone- single user) . I would like to have a expert opinion as whether this would be a scalable solution for an application which will support multiple users simultaneously . I am very new to ADF framework , so please advice
-The page are mostly inside bounded taskflows, which are nested and having backing beans are different scope. The backing bean is talking to a service layer (java classes ) to call the Webservice layer few database tables and then integrate and process the data to be shown on the front end.
(we have decided to opt out of drag and drop technique in ADF, due to some UI design reasons and large Webservice calls, though it is possible as mentioned by some experts)
The questions are based on the Database interaction, we have created an appmodule which has several VOs abased on entity objects and accessing them programmatically from the service layer like
1. Get the appmoduleDatacontrol via the id name in Databindings.cpx and get corresponding VO implementation classes to invoke custom methods written inside. How good would be the connection pooling and state management of the application modue in production environments.
2. for insertion - we call createROW on VO implementation and call an commit on the row implementation classes after adding detials to the new row.
3. for select op- we create filter criteria on the view and apply them programmatically to get the rows.
4. for update- get the row using the filters VO and manipulate the row using RowImpl classes and do a commit on then. (a commit on VO or commit on RowImpl, which would be better?)
Any pointers to tutorials/Blogs related optimizing and testing this implemtnation to this would be really helpful.
Thanks,

I need expert advice, which model should i buy 15 inch base model or with dedicated graphics card. i will use macbook for digital designing on Adobe photoshop and multi tasking. so now really confused is intel iris pro graphics will handle heavy files on photoshop or Nvidia GT750 m will good for heavy work. I am working on very large resolution file like 10 to 15k in resolution approx 1 GB in file size with lot of filters is being use while designing. Which model will handle above task well and last longer.

Look at the specifications here:

Required Expert Opinion

Dear All,
Required expert opinion about following points:
1) In peak hours our database concurrent session aprrox. 70-80 sessions
2) Can we configure shared server mode, presently our server configured dedicated mode??
3) If we go for Shared Server how much dispatchers and shared servers we define, we have 2GB memory and dual processor in Server Machine.
4) We have just 200 mb undo tablespace is it enough, we have done autoextended on, what is recommendation about it is it enough space??
5) We have just 3 online redo groups and each have 1 member, is it enough our alert log file continuously showing thread about redo file.
6) We don’t have archive log mode, and we just rely on Imp – Exp for backup, what is recommendation about it?
7) We didn’t multiplexing control files and redo log files, what is recommendation about it.
Regards,

6) We don’t have archive log mode, and we just rely on Imp – Exp for backup, what is recommendation about it?
depanding on ur database requirements if ur database have no downtime. ( 24x7) then "must" run ur database in archive log mode.
any why what is ur oracle version. ?
7) We didn’t multiplexing control files and redo log files, what is recommendation about it.
You must do multiplexing of ur control files. it is recommended and redo log file too.
) We have just 3 online redo groups and each have 1 member, is it enough our alert log file continuously showing thread about redo file.
it is ok but i check reguralary ur alert.log file if ur got any problem regarding redo log then increase member in group.
normal configuration like . 2 group and 2 member of each group. ( and also depand on nature of database).
4) We have just 200 mb undo tablespace is it enough, we have done autoextended on, what is recommendation about it is it enough space??
what is ur undo_retention = value .
but it ok.
plz specify ur database nature. further depand on nature of database.
how much undo generate in /sec.
2) Can we configure shared server mode, presently our server configured dedicated mode??
but why what is requirement.
hope this help
