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

• SQL * Net more data from client wait event

  Hi all

  DB 11.2.0.2

  AIX 6

  I get two events of high expectation of the AWR report page

  (1) SQL * Net more data from client

  synchronization of log files 2)

  Need advice to the configuration of the hardware and network latency?

  What should I do for the first event of waiting?

  This simple average may, what they're doing massive data loads with a very large table size that the Oracle Server manages very effectively but necessarily expect much coming data of the customer and parallel large log files written to end on the validation.  It is possible that setting a large SDU and tcp large transmiat and receive buffers would help if this happens to be what they do; Similarly, if that's what they do, then reduce their size of table can also have some effect.

• Difference between external tables and sql * loader

  Hello
  
  Could you please tell me the difference between
  tables external and sql * loader
  
  I have serached on the net but did ' get correct idea
  
  Please help me

  1 SQL LOADER can be run on the network (from any client computer), external tables can't

  2. return to the Oracle 9, external Tables could not load CLOB/BLOB (Oracle10 changed it)

  3 oracle 11 external tables have preprocessor, which is pretty dam characteristic cool - running essentially any OS command e.g. decompress before external table run. What's even better is the fact that the result of the operating system command is the source of the outer table, which means that there are no required temporary file (unzip the tracks and the output is the source of the external table). There are several ways to great use this - look at my blog for samples rare http://jiri.wordpress.com/2010/01/19/no-more-unix-scripts-in-11-2/

  4. as long as the 009 stressed, filed external load anything, they show just. Think of it more as load on request - it's great if you have old files archived and one or two users what to see content once a while

  5. external tables require no user access to the operating system, it is oracle environment pure - this may seem minor but for me it's huge. The fact that the ETL needs no special unix, no control file command and uses the simple SQL and DDL is nice and important

  6. external tables can load more text files, Oracle export dump files can be loaded, perhaps in the future more formats will be supported (hopefully all right excel format?)

  now the same thing to kill the myth - the TWO are EXACTLY the same when it comes to speed, I would actually drive of the external tables before will be faster because sql loader is old technology oracle doesn't really develops more

  We have recently to load a new language, but I'm not sure that this is the main problem.

  
  

  
  

  I think that you have the link db in the workspace schema and data requested by the Apex of this link. For example, it may be

  report which uses db link. Check dba_db_links or user_db_links for the existing links. Check if this link used by Apex.

• problem while browsing the table and tem records for data matching

  >
  Let me see if I understand. If you reach this part of the code:

  if ret_val1>0 0r ret_val2>0
  then
  l_return_out.has_csts := yes;
  l_return_out.cst_present := 10;
  l_return_out.cst_absent := 20;
  else
  l_return_out.has_csts :=No;
  l_return_out.cst_present:= 0;
  l_return_out.cst_absent := 0;
  end if;
  end loop; 
  

  You set values but DO NOT actually exit the loop - you just wrap around and continue. And the next iteration of the loop can actually delete these values and exit the loop.

  Even if these values don't get wiped out then when the loop ends you must run this code

  l_return_out.has_cst := student_rec(i).has_csts;
  l_return_out.cst_missing := student_rec(i).cst_present;
  l_return_out.cst_existing := student_rec(i).cst_absent;
  PIPE ROW(l_return_out);
  

  And this code permanently erases all the values in the first code that I showed and then DIRECTS the row.
  Each row that lead you has therefore values or NULL values for student_rec.

  This is the problem that you requested.

  But tell us why you use two tables and make two loops nested making slow down-by-slow (by line) treatment instead of using SQL for this?

• 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.

  Oracle Database 11g Enterprose 11.2.0.1.0 Edition

  Thank you in advance.

  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.

• Autocommit DDL: difference between SQL and SQL Developer * more?

  I asked this in the SQL forum (commit auto DDL: difference between developer SQL and command-line client?), but it has suggested it might be a problem in SQL Developer, so I thought I would ask here.
  
  I'm trying to understand what exactly happens when an error occurs when a transaction is committed because of a DDL statement. I noticed that with SQL Developer, if the DDL statement CREATE TABLE, the statement is executed, even if the DML statements which I entered before CREATE TABLE violates a deferred constraint, so that the transaction fails. In SQL * Plus, it's not the case: the table is not created. I have no automatic validation. I'm using Oracle 10 g XE.
  
  That's what happens in SQL * more:

  SQL> create table table1(a number);
  
  Table created.
  
  SQL> alter table table1 add constraint table1_a_uq unique(a) deferrable initially deferred;
  
  Table altered.
  
  SQL> insert into table1 values(1);
  
  1 row created.
  
  SQL> commit;
  
  Commit complete.
  
  SQL> insert into table1 values(1);
  
  1 row created.
  
  SQL> create table table2(b number);
  create table table2(b number)
  *
  ERROR at line 1:
  ORA-02091: transaction rolled back
  ORA-00001: unique constraint (BOEK.TABLE1_A_UQ) violated
  
  
  SQL> select * from table2;
  select * from table2
                *
  ERROR at line 1:
  ORA-00942: table or view does not exist

  If I put the same code in SQL Developer (versions 1.5.5 and 2.1.0.63), the table is created.
  This is my script:

  create table table1(a number);
  alter table table1 add constraint table1_a_uq unique(a) deferrable initially deferred;
  insert into table1 values(1);
  commit;
  insert into table1 values(1);
  create table table2(b number);
  select * from table2;

  And this is the output of SQL Developer:

  create table succeeded.
   alter table table1 succeeded.
  1 rows inserted
  commited
  1 rows inserted
  
  Error starting at line 9 in command:
  create table table2(b number)
  Error report:
  SQL Error: ORA-02091: transaction rolled back
  ORA-00001: unique constraint (BOEK.TABLE1_A_UQ) violated
  02091. 00000 -  "transaction rolled back"
  *Cause:    Also see error 2092. If the transaction is aborted at a remote
             site then you will only see 2091; if aborted at host then you will
             see 2092 and 2091.
  *Action:   Add rollback segment and retry the transaction.
  B                      
  ---------------------- 
  
  0 rows selected

  As you can see, the table is created in SQL Developer, but not in SQL * more.
  
  I wonder why it's different.

  Well Yes, it is a slightly different situation, because you issue 1 statement that executes internally 2 statements.
  But the problem is the same: the error handling. Where sqlplus rejects again (implicit) statements, sqldev goes ahead and runs them anyway. Personally, I'd say sqldev is more consistent and sqlplus is not, because run the following instructions (explicit).

  Kind regards

• TCPWARE instead of TCP and SQL * NET compatibility

  I use an oracle on VMS client, that connects to a base of oracle 11G windows on server 1.
  Everything works fine.
  
  2A TCPware server instead of TCP and while we compatabilities verfied for this product, when I
  set up I get the wonder 12154 TNS could not resolve the connect identifier.
  
  
  The customer Oracle on both servers are 10.2.0.2.0 and the database is 11 GR 1 material. As previously stated,
  Server there is no connection problem persists...
  
  my connection is made
  
  sqlplus/nolog
  connect sys/tester09@devorcl as sysdba
  devorcl is the machine of 11G.
  
  Any idea what might be different with the TCPWARE product? or how to test? I added a trace
  My sqlnet.ora file and nothing doesn't happen.

  ORA-12154 is a very basic problem, it means that what he says... "could not resolve identifier of connection...". Protocol of questions, if there is, come later.

  /*
  ORA-12154: TNS: could not resolve the specified connection Cause identifier: a connection to a database or other service has been requested using a login name, and the specified connection identifier could not be resolved into a connect descriptor using one of the configured naming methods. For example, if the type of connection identifier used was a network service name then the network service name is not found in a naming method repository, or the repository impossible located or reached.
  Action:
  -If you are using local naming (TNSNAMES. ORA file):

  S ' ensure that "TNSNAMES" is cited as one of the values of the NAMES. DIRECTORY_PATH parameter in the profile Oracle Net (SQLNET. ORA)

  -Check that a TNSNAMES file. ORA file exists and is in the appropriate directory and is accessible.

  -Check that the network service name used as the connect identifier exists in the TNSNAMES file. ORA file.

  -Make sure that there are no errors of syntax anywhere in the TNSNAMES file. ORA file. Search for unmatched parentheses or stray characters. Errors in a TNSNAMES file. ORA file can make it unusable.

  -If you use the directory naming:

  -Check that "LDAP" is one of the values of the NAMES. DIRETORY_PATH parameter in the profile Oracle Net (SQLNET. ORA).

  -Check that the LDAP directory server is in place and be accessible.

  -Check that the net service name or the database name as an identifier of connection is configured in the directory.

  -Check that the default context used is correct by specifying a full network service name or a unique display name of LDAP as the identifier of connection

  -If you use easy connect naming:

  -Check that "EZCONNECT" is one of the values of the NAMES. DIRETORY_PATH parameter in the profile Oracle Net (SQLNET. ORA).

  -Make sure that the host name, port and service specified are correct.

  -Try putting the identifier of connection between quotation marks. See the Oracle Net Services Administrator's Guide or the specific guide to the Oracle operating system for more information on naming.
  */

  Ensure connect you identifier "devorcl" can be solved on server 2. I'm not familiar with the virtual computers, so I don't know how to build an appropriate environment sqlnet. At least I know it's possible to connect virtual computers on any other platform.

• Tables and SQL query

  Hello
  
  I post this question for clarification. I have a report that is based on a SQL query area.
  
  Place automatically APEX sql in the tables, all THE results of a query if it is in a region of report? Or y at - it a step that the developer must do to retrieve the columns of the sql query in a table.
  
  I'm working with checkboxes, and I read up on top of the api APEX_APPLICATION. This part is still unclear.
  
  Your comments would be appreciated!
  
  Keisha

  Hi Keisha,

  You should have a read of: [http://download-uk.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/check_box.htm#CHDHFACG] that explains the use of checkboxes on the reports.

  I guess the 'picture' you refer to are APEX_APPLICATION. G_F01 up APEX_APPLICATION. Paintings of G_F50? If so, they are built when you submit the page and are based on elements with attributes of 'name' of 'f01' up to 'f50' in the HTML tags. You don't need to do anything beforehand to create these, which is done automatically for you by the Apex. But, notes, however, that only the checked boxes are presented with a page - so if your username is checked, say, 3 of the 10 boxes, table will contain only 3 points not 10 (with each element of the table that contains the attribute 'value' of a checkbox).

• use the queue and event to read data from two series mean

  Hi all

  You stop the second for loop using cluster of error which means that your upper and lower loop stops when you press exit but not the one in the middle. In theory, you should send a queue for loops below when you press the exit button and also make sure that you shoot hunting all queues before closing everything.
