Aside from making sure that our code compiles, we haven t bothered to put any other tests in We just set up our REST request and print out the response with the call to diag Recall from previous chapters how to run our test we run prove against our test file: CATALYST_DEBUG=0 prove -l t/controller_restt If we re lucky and the web service is up, we ll see a 200 status and a lot of JSON data about the named entities from the Snow White story If we re unlucky, we ll see a 502 error code and the error message telling us to try again shortly So with a controller based on Catalyst::Controller::REST, we don t need to set the stash and the HTTP status code manually (the returned HTTP status code is part of the REST web services specification).

If Opticon attempts to produce an image for which there is no original file, an error occurs. Processing halts, and as the administrator, you must provide feedback to the program before it can continue. For a large document production, this can be tedious. Selecting this option causes Opticon to record any errors in an ASCII file that can be opened with a text editor post-production. You can analyze the file, then repair any fault conditions that spawned errors. Concordance creates the error log when processing begins. You can manually key the file path and log name into the open text field, or use the Browse button to navigate to the desired folder.

A brief introduction of materialized views makes sense in this chapter about views. The intent of this section is to illustrate the concept of materialized views, using a simple example. Normally, materialized views are mainly used in complex data warehousing environments, where the tables grow so big that the data volume causes unacceptable performance problems. An important property of data warehousing environments is that you don t change the data very often. Typically, there is a separate Extraction, Transformation, Loading (ETL) process that updates the data warehouse contents. Materialized views are also often used with distributed databases. In such environments, accessing data over the network can become a performance bottleneck. You can use materialized views to replicate data in a distributed database. To explore materialized views, let s revisit Listing 10-1 and add a third DDL command, as shown in Listing 10-21. Listing 10-21. Comparing Views, Tables, and Materialized Views SQL> create or replace VIEW dept20_v as 2 select * from employees where deptno = 20; View created. SQL> create TABLE dept20_t as 2 select * from employees where deptno = 20; Table created. SQL> create MATERIALIZED VIEW dept20_mv enable query rewrite as 2 select * from employees where deptno = 20; Materialized view created. SQL>

We can use the status helpers from the controllers to deal with the common case However, what we have next is not a common case If our external web service fails, we ll want to return a 502 (bad gateway) response code and return some informative error message While we could write a status_bad_gateway method in our own controller, it s probably easier to just set the response status manually, and set the response in $c->stash->{rest} to an informative error message, as demonstrated in the else block in the index_PUT method In this case, a PUT and a POST request will be identical, so we can alias the index_POST subroutine to the index_PUT subroutine by adding the following line to Controller::REST: *index_POST = *index_PUT; What s happening in this code is that we use the helper subroutines provided by Catalyst::Controller::REST to return data and the appropriate response code.

You already know the difference between a table and a view, but what is a materialized view Well, as the name suggests, it s a view for which you store both its definition and the query results. In other words, a materialized view has its own rows. Materialized views imply redundant data storage. The materialized view DEPT20_MV now contains all employees of department 20, and you can execute queries directly against DEPT20_MV, if you like. However, that s not the main purpose of creating materialized views, as you will learn from the remainder of this section.

If the check box is enabled but no file name is provided, Option will suppress errors and continue processing. Errors won t be logged.
