How many bytes does a DATE use?
Having trouble finding this in the 10g documentation. How many bytes does a date data type use?
thanks.
Take a look to the online documentation linked below :
Oracle® Database SQL Reference
10g Release 2 (10.2)
Part Number B14200-02
Oracle Built-in Datatypes
expecially code datatype 12.
Valid date range from January 1, 4712 BC to December 31, 9999 AD. The default format is determined explicitly by the NLS_DATE_FORMAT parameter or implicitly by the NLS_TERRITORY parameter. The size is fixed at 7 bytes. This datatype contains the datetime fields YEAR, MONTH, DAY, HOUR, MINUTE, and SECOND. It does not have fractional seconds or a time zone.

It doesn't really matter if an AppleTV2 has to re-download since using the same bandwidth twice doesn't effect the user. There are no data caps on home internet like there are on 3G cellular service.
Many home internet services do have caps, at least in the UK, and I suspect elsewhere to. My current service is capped at 100GB/month for downloads, though I rarely use that much.
I recall a post from someone a few months ago who said that during the course of watching/rewatching a single HD rental they'd used over 20GB of their monthly usage allocation which is a significant chunk if you do have a cap.

How many bytes does a refresh check on the DDLOG table cost?
Hello,
each application server checks after "rdisp/bufrefreshtime" in the DDLOG table on the database whether one of it's tables or entries of tables are invalid.
Only tables or entries of tables that are invalid appear in the DDLOG table. If an application servers gets to know which of his tables are invalid, he can synchronize with the next read access.
Does anybody know how many bytes such a check cost?
The whole DDLOG must be read by each application server, so it depends on the number of entries in the DDLOG.
Does anybody know?
thx, holgerHi,
except of system and some timestamps, everything is stored in a raw field.
Checking FM SBUF_SEL_DDLOG_RECS I found some additional info:
- There are several synchronization classes
- Classes 8 and 16 don't contain table or key info -> complete buffer refresh
- Other classes should have a table name
- In this case is an option for a key definition
-> I guess, generic and single buffers are handled with corresponding key fields, full buffered is probably handled without key fields.
An entry in DDLOG itself is the flag / mark for: this buffer is invalid.
It's obviously single/generic key specific - otherwise the whole concept of single/generic key would be obsolete.

Having issues finding out how many bytes are sent/recieved from a socket.
Hello everyone.
I've searched the forums and also google and it seems I can't find a way to figure out how many bytes are sent from a socket and then how many bytes are read in from a socket.
My server program accepts a string (an event) and I parse that string up, gathering the relevant information and I need to send it to another server for more processing.
Inside my server program after receiving the data ( a string) I then open another port and send it off to the other server. But I would like to know how many bytes I send from my server to the other server via the client socket.
So at the end of the connection I can compare the lengths to make sure, I sent as many bytes as the server on the other end received.
Here's my run() function in my server program (my server is multi threaded, so on each new client connection it spawns a new thread and does the following):
NOTE: this line is where it sends the string to the other server:
//sending the string version of the message object to the
//output server
out.println(msg.toString());
//SERVER
public class MultiThreadServer implements Runnable {
Socket csocket;
MultiThreadServer(Socket csocket) {
this.csocket = csocket;
public void run() {
//setting up sockets
Socket outputServ = null;
//create a message database to store events
MessageDB testDB = new MessageDB();
try {
//setting up channel to recieve events from the omnibus server
BufferedReader in = new BufferedReader(new InputStreamReader(
csocket.getInputStream()));
//This socket will be used to send events to the z/OS reciever
//we will need a new socket each time because this is a multi-threaded
//server thus, the z/OS reciever (outputServ) will need to be
//multi threaded to handle all the output.
outputServ = new Socket("localhost", 1234);
//Setting up channel to send data to outputserv
PrintWriter out = new PrintWriter(new OutputStreamWriter(outputServ
.getOutputStream()));
String input;
//accepting events from omnibus server and storing them
//in a string for later processing.
while ((input = in.readLine()) != null) {
//accepting and printing out events from omnibus server
//also printing out connected client information
System.out.println("Event from: "
+ csocket.getInetAddress().getHostName() + "-> "
+ input + "\n");
System.out.println("Waiting for data...");
//---------putting string into a message object-------------///
// creating a scanner to parse
Scanner scanner = new Scanner(input);
Scanner scannerPop = new Scanner(input);
//Creating a new message to hold information
Message msg = new Message();
//place Scanner object here:
MessageParser.printTokens(scanner);
MessageParser.populateMessage(scannerPop, msg, input);
//calculating the length of the message once its populated with data
int length = msg.toString().length();
msg.SizeOfPacket = length;
//Printing test message
System.out.println("-------PRINTING MESSAGE BEFORE INSERT IN DB------\n");
System.out.println(msg.toString());
System.out.println("----------END PRINT----------\n");
//adding message to database
testDB.add(msg);
System.out.println("-------Accessing data from Map----\n");
testDB.print();
//---------------End of putting string into a message object----//
//sending the string version of the message object to the
//output server
out.println(msg.toString());
System.out.println("Waiting for data...");
out.flush();
//cleaning up
System.out.println("Connection closed by client.");
in.close();
out.close();
outputServ.close();
csocket.close();
catch (SocketException e) {
System.err.println("Socket error: " + e);
catch (UnknownHostException e) {
System.out.println("Unknown host: " + e);
} catch (IOException e) {
System.out.println("IOException: " + e);
}Heres the other server that is accepting the string:
public class MultiThreadServer implements Runnable {
Socket csocket;
MultiThreadServer(Socket csocket) {
this.csocket = csocket;
public void run() {
try {
//setting up channel to recieve events from the parser server
BufferedReader in = new BufferedReader(new InputStreamReader(
csocket.getInputStream()));
String input;
while ((input = in.readLine()) != null) {
//accepting and printing out events from omnibus server
//also printing out connected client information
System.out.println("Event from: "
+ csocket.getInetAddress().getHostName() + "-> "
+ input + "\n");
System.out.println("Lenght of the string was: " + input.length());
System.out.println("Waiting for data...");
//cleaning up
System.out.println("Connection closed by client.");
in.close();
csocket.close();
} catch (IOException e) {
System.out.println(e);
e.printStackTrace();
}Here's an example of the program works right now:
Someone sends me a string such as this:
Enter port to run server on:
5656
Listening on : ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=5656]
Waiting for client connection...
Socket[addr=/127.0.0.1,port=4919,localport=5656] connected.
hostname: localhost
Ip address: 127.0.0.1:5656
Waiting for data...
Event from: localhost-> UPDATE: "@busch2.raleigh.ibm.com->NmosPingFail1",424,"9.27.132.139","","Omnibus","Precision Monitor Probe","Precision Monitor","@busch2.raleigh.ibm.com->NmosPingFail",5,"Ping fail for 9.27.132.139: ICMP reply timed out",07/05/07 12:29:12,07/03/07 18:02:31,07/05/07 12:29:09,07/05/07 12:29:09,0,1,194,8000,0,"",65534,0,0,0,"NmosPingFail",0,0,0,"","",0,0,"",0,"0",120,1,"9.27.132.139","","","","dyn9027132107.raleigh.ibm.com","","","",0,0,"","","NCOMS",424,""
Now my program makes it all nice and filters out the junk and resends the new string to the other server running here:
Enter port to run server on:
1234
Listening on : ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=1234]
Waiting for client connection...
Socket[addr=/127.0.0.1,port=4920,localport=1234] connected.
Parser client connected.
hostname: localhost
Ip address: 127.0.0.1:1234
Event from: localhost-> PacketType: UPDATE , SizeOfPacket: 577 , PacketID: 1, Identifer: UPDATE: "@busch2.raleigh.ibm.com->NmosPingFail1" , Serial: 424 , Node: "9.27.132.139" , NodeAlias: "" , Manager: "Omnibus" , Agent: "Precision Monitor Probe" , AlertGroup: "Precision Monitor" , AlertKey: "@busch2.raleigh.ibm.com->NmosPingFail" , Severity: 5 , Summary: "Ping fail for 9.27.132.139: ICMP reply timed out",StateChange: 07/05/07 12:29:12 , FirstOccurance: 07/03/07 18:02:31 , LastOccurance: 07/05/07 12:29:09 , InternalLast: 07/05/07 12:29:09 , EventId: "NmosPingFail" , LocalNodeAlias: "9.27.132.139"
Lenght of the string was: 579
The length of the final string I sent is 577 by using the string.length() function, but when I re-read the length after the send 2 more bytes got added, and now the length is 579.
I tested it for several cases and in all cases its adding 2 extra bytes.
Anyways, I think this is a bad solution to my problem but is the only one I could think of.
Any help would be great!(a) You are counting characters, not bytes, and you aren't counting the line terminators that are appended by println() and removed by readLine().
(b) You don't need to do any of this. TCP doesn't lose data. If the receiver manages get as far as reading the line terminator when reading a line, the line will be complete. Otherwise it will get an exception.
(c) You are assuming that the original input and the result of message.toString() after constructing a Message from 'input' are the same but there is no evidence to this effect in the code you've posted. Clearly this assumption is what is at fault.
(d) If you really want to count bytes, write yourself a FilterInputStream and a FilterOutputStream and wrap them around the socket streams before decorating them with the readers you are using. Have these classes count the bytes going past.
(e) Don't use PrintWriter or PrintStream on socket streams unless you like exceptions being ignored. Judging by your desire to count characters, you shouldn't like this at all. Use BufferedWriter's methods to write strings and line terminators. -
If I am doing a serial read for a specific instrument, how do I know how many bytes are coming in.
The instrument is transfering data once every second.
The data is 20 lines total, each line ending with "\r\n".
Is there a way I can read in each line by successively reading a certain number of bytes?
Cory KI'm here with Ravens fan. Use a byte termination character.
After reading the port you will have exactly 1 (one) message. Then look how much more bytes are available at the port. If the number is big enough, do another read.
Make sure you keep fire reading events otherwise your buffer will burst (by default at 4k).

OutputStream: How many bytes are sent?
Dear Friends,
I use the following code to upload a file.
byte[] buf = new byte[5000];
int nread;
int navailable;
synchronized (in) {
while((nread = in.read(buf, 0, buf.length)) >= 0) {
//Transfer
out.flush();
out.write(buf, 0, nread);
out.flush();
buf = null;But how can I know how many bytes already are sent?
Is there a good way to do that?
Thank you!
With best regards
InnoOK, but don't be scared ;-)
EDIT: Does someone know why?
Do you need more information?
Only the function connect(), pipe() and the declarations are important.
Ignore all the other ones, please. :-)

How many parallel servers should I use?
Hello All,
I am in 10g and would like to create table as select. I am using NOLOGGING and PARALLEL. I notice, as I go on increasing the number of parallel servers, I cost of my statement reduces.
create table tmp_xyz NOLOGGING PARALLEL 12 as
SELECT ...
from ...
value of PARALLEL_min_SERVERS and PARALLEL_MAX_SERVERS parallel servers is 0 and 240 respectively.
I am doing this for a large data table migration; no user be working at the time.
I wonder how many parallel processes I should use?

I wonder how many parallel processes I should use? Each parallel process is used for doing I/O - the I/O load is what is parallelised. Each PX slave gets an I/O load (usually a rowid range that describes a range of physical row-on-disk addresses) to process.
So your question boils down to what the I/O capacity is of the I/O subsystem on that server. And this is pretty unique to a server and depends on just how the I/O layer looks like. -
How many bytes may I read in ???
I'm experimenting with the GPIB interface and a Fluke 45 dual display
multimeter.
But in the deliverd samplecode a number of bytes is read. How do I know
how many bytes I may read after a command. Is a big number alwys enough
and does this big number affect the speed of getting data ??
Any hint is welcome !
Thanx !
Kristofthe number is not critical. We normally ask for 256 characters and that does affect the speed not much. Most instruments are much slower than the pc !
It is wise to read enough characters and maybe it is slightly faster to stay within 32 characters.
These 32 character limit is only to prevent a new buffer to be setup for the gpib transfer. This happened in former years. I did not check this for visA2.5

How many bytes i get when i run some method through soap
Hi everyone,
I have a small problem. I have some web service. From wsdl file i create java classes (wsimport was used) and add them to my program. All works very good but i don't understand how to get information about how many bytes i get when i run some method.
For example i have a method:
service.getNewData(); How to check how many data i get BEFORE this method will complete.
I know that i can check Content-Length but how i can do it?

thanks
Edited by: user10919054 on May 18, 2009 3:07 AMThere is no limit, as long as you pay for the licenses and make sure you have a robust system to support user connectivity and demand.
Hyperion Enterprise is the previous Consolidation tool most commonly used by many companies. Think of HFM as the "New Generation".... -
How many messsages can we insert using JDBC receiver adapter in to DB
Hi Friends,
We are having 30 JDBC receiver interfaces in my current implementation project; load of JDBC receiver interfaces was 50 k messages per day and Performing only INSERT operation on data base.
We have created individual communication channel for every JDBC receiver interface and max concurrency value set in CC was 5.
Now we are testing all interfaces in quality with all possible cases, but we found that JDBC receiver adapter unable to process 50 k messages per day, we are on PI 7.1 EHP1 SP7.
Please share your experiences with JDBC adapter receiver like per day how many messages we can transfer.
Thanks a Ton,

Hi raj,
I have seen some interfaces that deal with upload of 5000 rows at a rime.. I don't there will be a restriction in the no of messages that can be transferred using the JDBC adapter as such unless until the requirement is so para-normal and in your case it is not
Kind regards

How many hours does a brand new battery last after fully charged. I have a late 2008 Macbook Pro.
How many hours does a brand new battery last after fully charged. I have a late 2008 Macbook Pro.
clintonfrombirmingham is right, there is no way to exactly tell. But from personal experience, a new battery on a 2008 will last for about 2 1/2 hours with a higher screen brightness and doing something taxing to the battery (like gaming or running lots of 3D programs). But if you're just listening to music with the brightness all the way down, and no programs running, you could get up to 12 hours. So for average use, it should last you a whole business day (assuming you don't use it more than 30% 0f the time). Hope this kind of gives you more of an idea of what to expect:)

How many pictures does a 30 GB ipod video hold?
how many pictures does a 30 GB ipod video hold? and i know it is probably somewhere on the website but i couldnt find it. could someone please answer me soon, thank you.
A 30GB iPod will hold as many photos as will fit in 27.75GB of space. If some of the iPod's capacity is used for music or other purposes, fewer photos will fit on the iPod. Apple's site specifies 25000 photos.
