• Lock on a table and SQL * Net more data from client

  Hello

  I have a problem loading data through Php in Oracle: web page of Php open an xml file, create a .csv, then begins to Oracle using an external table to process the data.

  The problem is that, the second time that PHP is trying to run the following query:

  INSERT INTO table1 T (Field1, Field2, field3, field4, sphere5, case field6) VALUES ('Aaa1E63819707', SYSDATE, 'KO', 'error', 'L', 'file_name.xml') POLL INTO Field1: id

  on the Oracle sessions, I have an exclusive lock on table1 and wait for SQL * Net more data from client.

  Where is the problem?

  Thank you

  Igor

  Finally I found the problem: a DBA changed the cursor sharing EXACT force! I restored the CORRECT setting and now everything is fine.

  Thank you

  Bye,.

• SQL to retrieve data from the day before

  Hello

  I am asked to collect intelligence data and generate a daily report to determine the success rate (to do daily data that determines success rate). I have a session_time of column (with the DATE data type) that I try to do the job. I've been using:

  Select * from ABC

  where session_time > = TRUNC (SYSDATE - 2)

  Gives me data, but I get the data from 26/10/14 and 10/28/14 so when I only need data on 27-10-14 (as of the day 28/10/14). I tried a few variations and did not get the expected result. Could someone please help me understand this? Time is also displayed in my outings, maybe I shouldn't include the time?

  I use: TOAD for Oracle 11.5.1.2.

  Use:

  SELECT *.

  ABC

  WHERE session_time > = TRUNC (SYSDATE) - 1

  AND session_time<  trunc="">

  ;

  It's 09:15 on October 28, 2014, then TRUNC (SYSDATE - 2) is 00:00:00 October 26; The query you posted became data of October 26 and later.  (You may not all future dates in your table.)

  If it's 09:15 October 28, then TRUNC (SYSDATE) is 00:00:00 October 28 (i.e., midnight, at the beginning of October 28) and TRUNC (SYSDATE) - 1 is 00:00:00 October 27.

  Do not be tempted to use

  WHEN TRUNC (session_time) = TRUNC (SYSDATE) - 1 * INEFFECTIVE!  ***

  It will get the same results, but it is slower, you cannot use an index on session_time and requires a call to separate function for each row in the table, it is selected or not.

• IPC vs SQL * Net connection

  Hi all
  
  My database is currently running on windows 2008 EE 10.2.0.4 (with all service packs). On the same machine, I have several workers (implemented as a windows service) written in c# .net using the latest drivers ODP.NET.
  To improve performance, I use PKI connection so that the TCP stack (which is used in the sqlnet connections "regularly") is shorted. I confirmed that ICP is actually currently in use:

  I read the ticket of Taner Poder [http://blog.tanelpoder.com/2008/02/07/sqlnet-message-to-client-wait-gotcha/] about SQNet message to the customer
  and his other observations on the SQLNet more data to the client [http://blog.tanelpoder.com/2008/02/10/sqlnet-message-to-client-vs-sqlnet-more-data-to-client/]
  to get the best understanding of them.
  
  The question is why observe specific SQLNet connection is when you use IPC connections?
  
  I enjoy all the comments.
  Thank you
  Rafal.

  Oh yes - one comment more.

  So that the server process indicate if the wait is over TCP/IP or IPC, he needs to know the mechanism of transport used.

  It is very likely that the wait event is registered by the server process when it is calling its send() data to the client API. As he calls the send(), it records that the current wait state. He has no idea what the underlying code uses as a transport mechanism. In server code and client, the transport layer is one of the lower layers. So earlier in the application code, you don't know what is the actual transport (remember that Oracle also support, or has supported, other layers of communication such as Lu6.2).

  So the application layer, you deal with the transport layer as a bit of a black box. In the Oracle terminology, this is called SQL * Net layer. And may be something that implements the transport layer.

  So, this is why it is dangerous to make assumptions that pending top-level State indicates what a low level wait state is.

  Run you the same Oracle_Home SQL and Server query as the ETL engine? (Want to use the same libraries and host and network such as ETL).

  The large data sets in ETL can be assembled with network optimization. Some of it is on the physical network layer (for example having a dedicated private network or a switched network between the ETL and the DB server), some of them can be found on the configuration settings (arraysize, configuring TCP settings to the OS layer, etc.) or libraries (for example JDBC libraries). Some of them may simply be patches to fix bugs!

• How to send data from the client to the server using tcp

  1. as I am new to watch I need help with sending data from client to server. I went through various examples of labview, but each of them also explains transfer of data to the client server. But I need help regardng send data from the server to the client.

  2.i would use the data type variant for sending my data.

  Can someone help me please. Thank you

  Regardless of the meaning. Once you have a connection each end allows it to send data to another. Just create what you want to look like interaction.

  Do you want the client sends a command that request data?
  How do you think the response data to look like?

  You can send variants, but probably not worth the effort.

  Hello. No explanation for this... :-(

  Hello

  people work here, you don't know?
  I think Tom Kyte explains it well enough. This wait event is linked to your session database waiting for the guest to say to do something.

  So it is not related to the database, but to your application.
  Also as it is a wait of session event you might have had your session inactive for some time (do nothing)

  If you want to check the waiting events correctly I suggest using tkprof and start a new session in SQL more as shown by Tom Kyte in the link I posted.

  Then, run your query in sqlplus setting track and pull it out as soon as your statement is completed.
  that is to say:

  -- myest.sql
  alter session set events '10046 trace name context forever, level 12';
  SELECT ... -- your query here
  exit
  

  Run in sqlplus in this way:

  sqlplus user/password@db @mytest.sql
  

  Then check with tkprof.

  Kind regards.

• Wait events, SQL * Net message from client

  Hi all

  I have a doubt about oracle wait events, specifically of "SQL * Net message from client. I've read a lot about this, I've seen some say that network and other material resources can provoke him, and saw that the problems in the application code can cause it too. I am tracking a few tests here and I don't have that chooses are the double event, usually a lot of SQL * Net message to client waiting (I used sqlplus, developer sql and pl/sql). Can someone explain to me why? Another question is where this wait type cause interference, meet it demand for the database and stays on hold and do not meet another request so that the wait is over, is it? The waiting just finish when the application closes the database connection or there is another way to end the waiting?

  Since then, thank you very much.

  Hello

  chooses double what usually causes a lot of SQL * Net message to client waiting

  Do you run them from your server applications or from the DB server itself?

  "SQL * Net client message" is an idle wait event although he'd still explain to the elapsed time of the query.

  It indicates only that the database is waiting for the other entries of the customer and when he expects the DB, those expectations get incremented.

  I suggest you explore size SDU, RECV_BUF_SIZE, and SEND_BUF_SIZE parameters.

• Collection of data from more than an instrument via the same labVIEW program

  Hello

  I have a program whereby I collect data on a scale of and save the data in the text file. Now, I need to collect data of three identical scales and save the data. I wonder if it is possible to do so in the same program? I mean how to manage three ports and save three different text files?

  I enclose the current program. Communication with the scale series and I use VI:s. thanks in advance for the help = VISA)

  

  This is easily possible with a single program, and there are several ways to do so.  I recommend the following:

  1. Take data from these devices in a separate loop (this could be in a separate - VI, as well).  These loops should be state machines if you can start and stop the acquisitions in a clean way.  This assumes that the instruments are on separate ports.  If they are on the same port, you probably want to use the same loop.
  
  
  2. Write to the file in a single loop.  This, too, should be a state machine.
  
  
  3. Queues to send data from the acquisition of loops to the loop of file I/O.
  
  
  4. Use still another loop for your user interface.  It must contain a structure of the event.

  To do this, you will need to learn more about the State machines and producer/consumer architectures.  Start with the help of LabVIEW, then search these forums.  There are a multitude of implementations of State machines and producer/consumer architectures.  If you have the time, I highly recommend you learn and to use the classes in LabVIEW (requires LabVIEW 8.2 or later).  This will facilitate your work in the long term.

• Loading data from SQL to Essbase table

  Hello

  I'm loading data from SQL to Essbase table by using a rules file. Number of rows in the source table is 7 million. I use the SUNOPSIS MEMORY ENGINE as area transit, LKM SQL for SQL and SQL IKM for Hyperion Essbase (DATA).

  Question:

  1 can I not use any other LKM as MSSQL for MSSQL (PCBS) to load data to the staging instead of LKM SQL for SQL? What I have to change the transit area then? Loading data using LKM SQL for SQL seems quite slow.

  2 it is mandatory to use LKM SQL for SQL, can someone please tell me what I can change to make this quick support parameters?

  3. is it compulsory to use the SUNOPSIS MEMORY engine loading data from SQL server to Essbase?

  Thank you...

  (1) Yes, I highly recommend watching using a KM which uses native as database technology these will usually be more efficient than the generic (like LKM SQL for SQL) KM especially when large volumes of data are involved. Your staging will change depends on where you organize data for example if you are using a SQL server specific KM as - MSSQL for MSSQL (PCBS) - you must have a lay-by available on a MSSQL database and have access to the utility of PCBS.

  (2) it is not mandatory to use this KM you can use a KMs supported by your database technology

  (3) it is absolutely not obligatory to use the SUNOPSIS MEMORY engine. This should only be used when you have relatively small amounts of data, as well as all the processes in memory, or in the case where you have no other relational technology to perform the staging on. However, in your case to use wherever you are processesing these large volumes of data you should be staged on a physical such as SQL Server or Oracle database if they are available.
