Package Subprograms Subprogram Description CREATE_ERROR_LOG Procedure Creates the error logging table used in DML error logging CREATE_ERROR_LOG Procedure This procedure creates the error logging table needed to use the DML error logging capability. LONG, CLOB, BLOB, BFILE, and ADT datatypes are not supported in the columns. Syntax DBMS_ERRLOG.CREATE_ERROR_LOG ( dml_table_name IN VARCHAR2, err_log_table_name IN VARCHAR2 := NULL, err_log_table_owner IN VARCHAR2 := NULL, err_log_table_space IN VARCHAR2 := NULL, skip_unsupported IN BOOLEAN := FALSE); Parameters Table 52-2 CREATE_ERROR_LOG Procedure Parameters Parameter Description dml_table_name The name of the DML table to base the error logging table on. The name can be fully qualified (for example, emp, scott.emp, "EMP", "SCOTT"."EMP"). If a name component is enclosed in double quotes, it will not be upper cased. err_log_table_name The name of the error logging table you will create. The default is the first 25 characters in the name of the DML table prefixed with 'ERR$_'. Examples are the following: dml_table_name: 'EMP', err_log_table_nam
TECHNOLOGY: Performance Faster Batch Processing By Mark Rittman LOG ERRORS handles errors quickly and simplifies batch loading. When you need to load millions of rows of data into a table, the most efficient way is

usually to use an INSERT, UPDATE, or MERGE statement to process your data oracle dbms_errlog in bulk. Similarly, if you want to delete thousands of rows, using a DELETE statement is usually faster than using procedural oracle merge log errors example code. But what if the data you intend to load contains values that might cause an integrity or check constraint to be violated, or what if some values are too big for the column they https://docs.oracle.com/cd/B28359_01/appdev.111/b28419/d_errlog.htm are to be loaded into? You may well have loaded 999,999 rows into your table, but that last row, which violates a check constraint, causes the whole statement to fail and roll back. In situations such as this, you have to use an alternative approach to loading your data. For example, if your data is held in a file, you can use SQL*Loader to automatically handle data that raises an http://www.oracle.com/technetwork/testcontent/o26performance-096310.html error, but then you have to put together a control file, run SQL*Loader from the command line, and check the output file and the bad datafile to detect any errors. If, however, your data is held in a table or another object, you can write a procedure or an anonymous block to process your data row by row, loading the valid rows and using exception handling to process those rows that raise an error. You might even use BULK COLLECT and FORALL to handle data in your PL/SQL routine more efficiently, but even with these improvements, handling your data in this manner is still much slower than performing a bulk load by using a direct-path INSERT DML statement. Until now, you could take advantage of the set-based performance of INSERT, UPDATE, MERGE, and DELETE statements only if you knew that your data was free from errors; in all other circumstances, you needed to resort to slower alternatives. All of this changes with the release of Oracle Database 10g Release 2, which introduces a new SQL feature called DML error logging. Efficient Error Handling DML error logging enables you to write INSERT, UPDATE, MERGE, or DELETE statements that automatically deal with certain constraint violations. With this new fea

My application inserts data from xml file into Oracle. I started my application last day and went home. It stopped unexpectedly at 8PM. There is no log in application why the insertion stopped. I want to check Oracle log file to check what exactly the error was and why the Oracle stopped inserting data. I have log.xml file and multiple *.trc and *.trm file. I don`t log in oracle know how to start with this. I just have to check the error that why the Oracle has stopped. oracle share|improve this question asked Dec 24 '12 at 5:51 Nitesh Kumar 1701311 migrated from stackoverflow.com Dec 24 '12 at 11:51 This question came from our site for professional and enthusiast programmers. add a comment| 2 Answers 2 active oldest votes up vote 1 down vote Aside from what maialithar said, you can also check the alert_yourSID.log or the listener.log share|improve this answer answered Jan 23 '13 at 12:02 Avias 7217 add a comment| up vote 0 down vote You have to open and read your log.xml file.

major new feature of Oracle 10g Release 2 for bulk SQL operations. DML error logging enables us to trap "bad data" and filter it to a log table without failing our overall DML statement. This has never been possible in SQL before, although we could use complex constraint management and application code to achieve a slightly similar end-result. DML error logging is more similar in concept to the FORALL SAVE EXCEPTIONS construct in PL/SQL (new in Oracle 9i). overview of dml error logging With this feature, we can add a clause to our bulk DML statements (INSERT, UPDATE, MERGE and DELETE) to prevent the statement failing on hitting exceptions (i.e. "bad data"). Exceptional rows are added to a specifically-created errors table for investigation and/or intervention. In addition, we can control the number of bad records we will tolerate before failing the entire statement. There are two components to DML error logging as follows: LOG ERRORS clause to DML statements; and DBMS_ERRLOG package for managing error tables. We shall examine both of these components in this article, but first we will create some sample tables. getting started: sample data We will use two tables in our DML error logging examples, as follows. Note that for the examples, I created a user named EL with just CREATE SESSION, CREATE TABLE and a tablespace quota. SQL> CREATE TABLE src (x,y,z) 2 AS 3 SELECT object_id 4 , object_type 5 , object_name 6 FROM all_objects 7 WHERE ROWNUM <= 5; Table created. SQL> CREATE TABLE tgt 2 AS 3 SELECT * 4 FROM src 5 WHERE ROWNUM <= 3; Table created. SQL> ALTER TABLE tgt ADD 2 CONSTRAINT pk_tgt 3 PRIMARY KEY (x); Table altered. We have a source table (SRC) and a target table (TGT). The data is setup in such a way that a standard INSERT..SELECT from SRC into TGT will fail, as follows. SQL> INSERT INTO tgt SELECT * FROM src; INSERT INTO tgt SELECT * FROM src * ERROR at line 1: ORA-00001: unique constraint (EL.PK_TGT) violated On this basis, we can now introduce the new DML error logging feature. To begin, we will require an exceptions table. creating the error log table DML error logging works on the principle of trapping exceptions in bulk SQL statements and re-directing the "bad data" to an error table. The error table is created using an API in the new DBMS_ERRLOG package. The minimum amount of information we need to supply to this is the name of the target table we wish to trap exceptions for. Oracle will by default create an error table named "ERR$_SUBSTR(our_tabl
