Slow nfs read/write from solaris 8 to solaris 10

there is a bug:4852269 which sums up my problem well.
I have a solaris 10 sparc with a big nfs shared raid5, and most of the other suns I have run solaris 8. the access time from sol8 to sol10 is awfull.
Is there some config/patch I can apply to the solaris 10 box?
I have put on the latest 10_Recommended.zip

it's a ufs filesystem
If it helps, here is my /etc/default/nfs

Read/write from OBIEE repository data using API

Hi, I need to create a my own application that could read/write from the repository data, the same as I can do using the BI Admin user interface (like creating dimensions, hierarchies, levels, etc.).
Are there any API's to do that?
I'm usually working with .NET/C# technology but I can also programming in Java, the important is that I could be able to write metadata in the repository, and simply read them, I'm not interested in complex report functions... any suggestion will be appreciated!

I've looked for it before, but I didn't find anything about BI Server accessing, so I requested on this forum. After that I've looked for another kind of API and I've found these about web services!
In the PDF I linked says:
"Oracle BI Web Services allows external applications such as J2EE and .NET to use Oracle Business
Intelligence as an analytical calculation and data integration engine. It provides a set of Presentation
Services that allow external applications to communicate with Oracle BI Presentation Services. You
can use Oracle BI Web Services to extract results from Oracle BI Presentation Services and deliver
them to external applications and Web application environments. You can reference a saved report
or send the criteria for the report to Oracle BI Web Services."
without talking about Metadata, but in this another tutorial http://oraclebizint.wordpress.com/2007/07/31/customizing-obi-ee-soap-api/ talks about "metadata"... is it only about Presentation Service? Has Presentation Service metadata too? Are they like Dimensions and hierarchies?
Excuse me but although I've read the documentation I can't understand what kind of metadata it refers to...

Read/Write from an Applet

Can everybody send me an simple example.

You are right and I have try it.
There are some guys with the same problem but there are no answers to the specified problem.

Sharing directories READ/WRITE from Global Zone

I would appreciate some advice on the configuration of a machine in a client's environment.
I have a global zone on a v880 running Solaris 10, with 4 sub zones. The v880 has 2 A1000's connected to it.
One A1000 is mounted as /storage0, and the other as /storage1, with both having subdirectories called "zone1" "zone2" "zone3" and "zone4".
There is a requirement to have the /storage0/zoneX directories mounted READ/WRITE onto the appropriate zone as /data/rawdata, and the /storage1/zoneX directories mounted READ/WRITE onto the appropriate zone as /data/processeddata.
My client's environment where my hardware is located runs DHCP to assign IP addresses (and the DHCP server is non-Solaris).
My global zone has picked up an IP address over DHCP with no problem - I only had to modify /etc/nodename and /etc/hosts to ensure that the domain had its own name (i.e. it was not named "unknown".
In order to mount the filesystems READ/WRITE on the sub-zones, I thought there were 2 ways to proceed.
1) Give each subzone an IP address, NFS share the directories to be mounted, and mount them on each sub-zone as READ/WRITE....
HOWEVER, as stated, the client is on DHCP, and zonecfg seems to only allow us to set a static address. Is there a way to configure zones to pick up their IP addresses from a DHCP server?
ALSO - if I went down this route, would I have a massive overhead on NFS server?
2) Add the /storageX/zoneX directories to each zone as an "add-inherit-dir", and NOT configure each sub zone as a network presence.
HOWEVER, when I trialled this, the zones mount the file systems as READ ONLY. Is there a way to get the zones to mount the file systems as READ/WRITE?
ALSO - without the network presence, when I try to change user passwords on the zones, I get an error message of "passwd[5051]: passwdutil.so: can't get domain. Permission denied".
Actually, as I type this, I've thought of a third.... Is there a way to share the same IP address and network interface across mutliple zones and a global zone? If so, this may be the best method.... But how do I configure it?
Any assistance would be appreciated.

It's not "supported", but that's because RM6/RDAC doesn't work on Solaris 10.
If the array is configured, it just appears as a normal scsi device and it works fine. You just can't modify the configuration or monitor its status. Not something I'd do in production, but I might stick one on a non-production host.

Can PL/SQL read/write from a database server to another server?

hi,
please advise.
thanks

what i mean is output text file to other servers using pl/sql through utl_file package.No. utl_file reads/writes only on the server where your pl/sql code is running.
But maybe you could map a network drive. Haven't tried that.

Read/Write from FAT/NTFS volumes

I have a Windows/DOS formatted external harddrive adn want to access/write/delete data from it using my MCP with Lion OS. I downloaded
NTFS-3G 2011.1.15 and installed and restarted my Mac but then got this error when OS started
and I cant see my Windows external disk any more. I am not 100% sure if the format of this disk was FAT or NTFS. Any idea what's going wrong and what I can do about this ?
Any other suggestions for a application instead of the one I downloaded ?

I have uninstalled NTFS-3G now, and am again able to see my external HDD in Finder. Then I look for MacFuse on Spotlight and click on Macfuse in system preferences. Finally I get this - not sure how to go forward ?

How to read/write from Access database

Hi everybody
I need a little help for doing what I wrote in the topic!
I use LabVIEW 6i student edition, do Ireally need to install the Database
connectivity toolkit?

Hi Vicio,
There are a couple of different methods to communicate with Access in LabVIEW, and some are more difficult than others. You can use ActiveX Automation to open Microsoft Access and control many aspects of the Access Application. For actual database manipulation however, the Access automation classes rely upon the Microsoft DAO (Data Access Object) and/or ADO (ActiveX Data Object) classes. These classes can be used independently or through the Access automation classes to read and write data into an Access database. These classes can be difficult to use and may require a fair amount of SQL knowledge to accomplish a complicated task. Attached is a very simple example of how you can use DAO from the Access automation classes to read an Access table.
For more information about the Microsoft Access automation classes, DAO or ADO classes refer to the Microsoft website and Developer Network:
MSDN
It is also possible to use Dynamic Data Exchange (DDE) communication between LabVIEW and Access. DDE is a Microsoft technology that preceded COM and ActiveX. DDE is NOT recommended as it is considered by most to be obsolete. However, examples still ship with LabVIEW that demonstrate how to communicate with MS Access using DDE. The examples are located in ..\LabVIEW\examples\comm\access.llb
Note: The LabVIEW Database Connectivity Toolset is the preferred method of database communication with LabVIEW. The LabVIEW Database Connectivity Toolset offers many powerful tools and extended capabilites for quickly accessing databases. The LabVIEW Database Connectivity Toolset offers connectivity to most popular databases through Microsoft ADO technology, complete SQL Functionality, and the ability to save records in XML format. It provides both easy-to-use and advanced functions to allow common database operations as well as detailed database accessibility. The LabVIEW Database Connectivity Toolset is sold separately or in the LabVIEW Enterprise Connectivity Toolset along with the LabVIEW Statistical Process Toolkit and the LabVIEW Internet Developers Toolkit.

Read & write from external files in java

Hello everybody,
I need your help in two problems. I have to write a method that read specific numbers from a file, save them in an array, do some calculation on that array and write it again in a new file.
For example, I have a file that contains the following:
#VRML V1.0 ascii
Material {
diffuseColor [ 1 1 1 ]
ShapeHints {
vertexOrdering COUNTERCLOCKWISE
shapeType UNKNOWN_SHAPE_TYPE
Coordinate3 {
point [
          1 0 0 ,
          1 1 0 ,
          1 1 1 ,
          1 0 1 ,
          0 1 0 ,
          0 1 1 ,
          0 0 1 ,
          0 0 0 ,
IndexedFaceSet {
coordIndex [
0,1,2,-1,
0,2,3,-1,
1,4,5,-1,
1,5,2,-1,
3,2,5,-1,
3,5,6,-1,
0,3,6,-1,
0,6,7,-1,
6,5,7,-1,
7,5,4,-1,
0,7,4,-1,
0,4,1,-1,
I need to read the point coordinates only and save them in a two dimension array, then I'll do some transformation on that array and write it in a new file that contains the previous data but the point coordinates are the transformed coordinates. I tried the following:
FileReader in = new FileReader("C:\\hexahedron.txt");
          BufferedReader br = new BufferedReader(in);
          String line;
          StringTokenizer s;
          int [][] point = new int [8][3];
          int row = 0;
          int column;
          while ( (line = br.readLine()) != null) {
               s = new StringTokenizer(line);
               column = 0;
               while (s.hasMoreTokens()) {
                    if ( s.nextToken() == "[" ){
                         point [row][column++] = Integer.parseInt(s.nextToken());
               row++;
          br.close();
          in.close();
But when I tried it, I found out that it saves 0s in the array!
As I mentioned before, my problem is that I don't know how to read specific information from a file. I know how to write new information a file, but how to write a file that I already have with changed specific information.
I'll be grateful if you show me how to solve those problems.
And I hope that I explained my problems in an understandable and clear way.
Regards,

if ( s.nextToken() == "[" ){should beif (s.nextToken().equals("["){Also, you have two nextToken for each has hasMoreTokens, which is going to cause an exception.
You are never hitting the parseInt code because of your equals/== error. Therefore, everything is zeros.
The order of reading lines and checking for "[" isn't right. You should find the [ (maybe including the "point" word), then get numbers from the following lines (read line, tokenize, read line, tokenize, ...) until you hit the end of the points.

Extremely slow card reader (write speed: 20 mb/s)

Hey Folks,
I got a MacBook Pro with Retina Display and an internal card reader. I bought some SD cards with speeds of 45 mb/s (write) and 90 mb/s (read). I tested them on a external USB 3.0 card reader and so I got nearly this speeds, but the internal card reader of my mac reads with 25-40 mb/s (it's ok), but writes only with 15 up to 20 mb/s.
I already checked the link speed in the system information: 2.5 GT/s, so it has to be connected with PCIe and not USB, but I can't figure out where the problem could be.
Any suggestions?

Write n then read xml from database to create graph in an applet

Hi mates
I have one problem I want show a trend(graph) from sql database which is having the records of about 8600 in a day. And i want to show a graph for a day
but sometimes it gives a problem like out-of-memory, so can anyone tell me how i can get read of it.
and other this can i use xml for this means first write a data in xml format from database then read it at sametime and show graph in applet
can anytell me how to do it
any suggesion is appreciable
thanx

Here's are two example for what you are looking for
Re: Load xml data in Oracle table
Re: insert .xml file into xmltype table?
First you need to create a DIRECTORY object. That is how Oracle works and it expects a DIRECTORY object instead of a physical path when performing operations that read/write from disk. The directory path provided to the CREATE DIRECTORY command must be a directory that the machine Oracle DB resides on can see.
Then you can go either of two routes. You can INSERT that XML directly into a table, as shown in the second link I provided or you can read it into PL/SQL as the first link shows. Then in either case, you can use SQL to parse the XML for you.
Depending upon your needs, you may get better performance if you insert the XML into a table as the second link shows, assuming the XMLType column is stored as SECUREFILE BINARY XML.

HT1549 How do I read write to an external drive? I am under admin account and cannot read write to any folder on the external drive.

I have a Mac Mini with Mavericks installed, as well as a PC running Windows 7. I want to be able to read write from both computers to an external drive on the Mac. I created 2 folders on the drive and named them Movies, and TV Shows. The content of those folders are the respective files. I set up both folders to be shared on the Mac under system preferences, and then mapped the drives on the PC. I also created a user account with admin privileges on the mac that matched my PC. I then copied a Music folder to the root drive instead of using external, and set up sharing as well. File Sharing is selected for all three folders, however the music folder is the only one which allows me to change the permissions to allow read write to everyone, or to create individual user accounts to connect with read write permissions. The options to add users or change permissions are simply grayed out for the two folders on the external drive, so not only can I not write from my PC, but I can’t even do it on the Mac with the administrative user logged in. The folder on the root drive is fine but I cannot make any changes to the external drive at all. Get info for any folder on drive shows read only. SMB and AFP are selected for all folders under options. I can access all three folders from PC, but can only add files to the Music folder. I cannot do anything from either computer to the folders on the external drive.

Try Applications/Utilities/Disk Utility - select the drive and run Repair Disk.
