Import the certificate to the java trusted certification store at the OC4J server side. $JAVA_HOME/bin/keytool -import -v -trustcacerts -file $JAVA_HOME/jre/lib/security/server.cer -keystore $JAVA_HOME/jre/lib/security/cacerts where cacerts is the file used One of the drawbacks in the 10gR2 implementation of DML Error Logging was when you tried to use it in conjunction with conventional path inserts, which for whatever reason caused the SQL> DESC err$_dest Name Null?
Etl Error Handling Best Practice
Audit data regarding deployments to this target schema is written to audit tables in the Control Center repository. Log in as the OWBSYS user and run the following query to determine if the location is still associated with a Control Center. By entering a name such as ‘PROD_ERRORS’ you will enable DML error logging on that table, the table will be created if it does not exist when the mapping is deployed. Figure 15-1 displays the validation messages in a new tab of the Message Log window.
When you attempt to use a different Control Center to deploy a mapping to the same target schema, you encounter the REP-01012 error. The Code Template mapping execution logs are stored in the OWB_HOME/owb/jrt/log/owb folder. About Us Rittman Mead consults, trains, and innovates within the world of Oracle Business Intelligence, data integration, and analytics. Using DML Error Logging Error logging enables the processing of DML statements to continue despite errors during the statement execution.
For the mapping that was going to use DML Error Logging, I just copied the columns from the source table into the target table, like this: To turn on the DML After the DML operation completes, you can check the error table to correct rows with errors. It is useful in long-running, bulk DML statements. You can view this log of deployment and error messages from Oracle Warehouse Builder console by selecting View from the menu bar, and then Log.
You can also select the types of logs to store. All new database and data warehouse technical terms and concepts explained in clear easy-to-understand language. In Oracle 10g Database Release 2, the DML error logging feature has been introduced to solve this problem. This can be done manually or with the CREATE_ERROR_LOG procedure in the DBMS_ERRLOG package, as shown below. -- Create the error logging table.
Etl Error Handling Strategy
Once the basic tables are in place we can create a table to hold the DML error logs for the DEST. A target schema can be associated with only one Control Center. Etl Error Handling Best Practice The following are the agent logs on UNIX: The jrt.log file located in OWB_HOME/owb/bin/admin contains output from the Agent process and audit setup errors. Error Handling In Etl Process UPDATE or MERGE operations raise a unique constraint or index violation.
Solution Drop the mappings that have been deployed to the target schema using the original Control Center. To truncate an error table before the map is run, select the Truncate Error Table property of the operator bound to the data object that has DML error logging enabled. For example, direct-path insert does not support error logging for unique key violations. So there is no need to join these two tables or to import the logging error table to retrieve rows from.
- If you've licensed the Data Quality Option for OWB, as an alternative you can define a data rule and attach it to a table, which again makes warehouse builder direct all
- You can deploy mappings to a target schema by using a Control Center installed on a different database than the one that contains the target schema.

- When DML error tables are created along with the mapping, dropping the mapping causes the DML error tables to be dropped, too.
- Register the location using the new Control Center.
- If the value is set to Default, ensure that location associated with this module has the Version property set to 10.2, 11.1, or 11.2.
- You are prompted for the cacerts password.
- DML error logging is : supported only for target schemas created in Oracle DB 10g R2 or later.
- If you use an OC4J instance other than the one embedded in Oracle Warehouse Builder, serverkeystore.jks is the key store file you created when you setup the SSL with OC4J.

You can create your own tables to store DML errors or enable Oracle Warehouse Builder to generate the DML error table. CREATE TABLE "MDM_VENDOR_ERR" ( "ORA_ERR_NUMBER$" NUMBER, "ORA_ERR_MESG$" VARCHAR2(2000), "ORA_ERR_ROWID$" ROWID, "ORA_ERR_OPTYP$" VARCHAR2(2), "ORA_ERR_TAG$" VARCHAR2(2000), "ERR$$$_AUDIT_RUN_ID" NUMBER(22), "ERR$$$_AUDIT_DETAIL_ID" NUMBER(22), "ERR$$$_ERROR_ID" NUMBER(22), "ERR$$$_ERROR_REASON" VARCHAR2(2000), "ERR$$$_SEVERITY" VARCHAR2(1), "ERR$$$_OPERATOR_NAME" VARCHAR2(30), "ERR$$$_ERROR_OBJECT_NAME" VARCHAR2(30), "ADDRESS" VARCHAR2(35), "CITY" SQL> The structure of the log table includes maximum length and datatype independent versions of all available columns from the base table, as seen below. Looking into the code for the mapping you will see where it attempts to create the DML Error logging table if it does not exist using the DBMS_ERRLOG.CREATE_ERROR_LOG procedure.
To turn on this features without OWB - Data Rules, you have to fill the error table name property parameters for DML Error logging in the Error Table Properties from the In the Locations Navigator, create a Control Center that points to the Control Center installed on the remote host containing the target schema. Figure 15-2 displays the Generation Results window.
LOG ERRORS [INTO [schema.]table] [('simple_expression')] [REJECT LIMIT integer|UNLIMITED] The optional INTO clause allows you to specify the name of the error logging table.
This book is an update of Oracle Warehouse Builder 11g: Getting Started. What about if we run the conventional path insert without the LOG ERRORS clause? Typically, when you use a Control Center for deployments, you deploy mappings to a target schema by using the Control Center installed on the database containing the target schema. Taking a look at the generated code, it's clear that the mapping isn't using DML Error Logging; it still creates a few test selections, works out whether any errors have occurred,
Let's run the first one again, take off the LOG ERRORS clause but remove the rows that could cause an error. COLUMN ora_err_mesg$ FORMAT A70 SELECT ora_err_number$, ora_err_mesg$ FROM err$_dest WHERE ora_err_tag$ = 'INSERT'; ORA_ERR_NUMBER$ ORA_ERR_MESG$ --------------- --------------------------------------------------------- 1400 ORA-01400: cannot insert NULL into ("TEST"."DEST"."CODE") 1400 ORA-01400: cannot insert NULL into ("TEST"."DEST"."CODE") UPDATE dest SET code = DECODE(id, 9, NULL, 10, NULL, code) WHERE id BETWEEN 1 AND 10; * ERROR at line 2: ORA-01407: cannot update ("TEST"."DEST"."CODE") to NULL SQL> As expected, Errors occur due to functionality that is not supported.
A log table must be created for every base table that requires the DML error logging functionality. SAVE EXCEPTIONS method. As a quick recap, Warehouse Builder from 10.2.0.3 onwards lets you enter an "Error Table" name for each target table in a mapping, wherapon it will insert a LOG ERRORS clause From Dave Allan, since the 10.2.0.3 patch the data rule enabled map can also be executed set based, there were some fixes to support set based delete that made this possible.
He has been working in various roles involving database development and administration with the Oracle Database with every release since Version 6 of the database from 1993 to the present. You can easily access these error reports using the Run time Audit Browser.

DELETE FROM dest WHERE id > 50000; MERGE INTO dest a USING source b ON (a.id = b.id) WHEN MATCHED THEN UPDATE SET a.code = b.code, a.description = b.description WHEN NOT The following example displays the code generated, in set-based mode, for a Filter operator. SAVE EXCEPTIONS method.
Taking a look at the mapping code that OWB generates for this, you can see the LOG ERRORS clause in place: INSERT /*+ APPEND PARALLEL("SALESTARGETCON") */ INTO "SALESTARGETCON" ("SALESID", "CUSTID", "PRODID", Click the Execution tab in the Execution reports to view error messages and audit details. Subscribe or subscribe via RSS with Feedly! This is because Oracle Warehouse Builder does not maintain auditing information for these objects.
The mapping itself performed the same load logic as the SQL statements beforehand.
