Rational Developer for System z (v9.0.1): Integrated Debugger- This video features the new Integrated Debugger that is part of Rational Developer for System z, version 9.0.1. This debugger is much more than your typical debugger. In this video you'll become familiar with the debug perspective, learn how to submit a job in debug mode or code coverage, access the full feature editor, step through a program, add, monitor, filter, label and search for variables and breakpoints, work with complex variables, easily navigate large programs using the Outline or Program Code Flow views, and use Monitor memory to display results in different formats.
Here's a great new tutorial from TheOnDemandDemoGuy covering theRational Developer for System z (v9.0.1): Integrated Debugger- This video features the new Integrated Debugger that is part of Rational Developer for System z, version 9.0.1. This debugger is much more than your typical debugger. In this video you'll become familiar with the debug perspective, learn how to submit a job in debug mode or code coverage, access the full feature editor, step through a program, add, monitor, filter, label and search for variables and breakpoints, work with complex variables, easily navigate large programs using the Outline or Program Code Flow views, and use Monitor memory to display results in different formats.
If you are a new user of Rational Developer for System z (RD/z), this document is intended to help you get started on debugging Cobol programs on z/OS. The example shown here is for a simple Cobol program for a batch runtime environment.
It is assumed that you have installed RD/z (for example RDZ 9.0) on your client platform, and have set up connection to the RD/z host component using Remote System Explorer.
The images show in this document are from from RD/z client. It is assumed that you are working on an RD/z Eclipse client IDE and are familiar with navigation on the IDE.
Step 1: Verify that debug Listener is configured and operational
Switch to Debug Perspective:
Click on UI Daemon Listener:
Typically the listener will be listening on port 8002.
Step 2: Set the property group for the program to be debugged
In this example we select program MYMAIN.cbl in a z/OS project .
In the property group, set the normal Cobol compile settings, and select the Run tab
Step 3 - Select the program and debug
To debug the program you will create a JCL file for compile link and go. the go step will contact the listening daemon.
In this case the JCL is in a member named MYMAIN in MAHADEV.BATCH.JCL
After the generation of JCL is complete, you may submit it to launch the debugger.
This will take you to the interactive debug window.
Over the years, many clients have developed their own programming practices and naming standards to reinforce company policies. When editing workstation source files (COBOL or PL/I) with non-standard file extensions, the file extensions have to be defined to Eclipse in order to be recognized by the Rational Developer for System z (RDz) editors. This technical blog will further describe in detail the steps involved for adding the file extensions to Eclipse's general "Content Types".
This example demonstrates how to add two new file extensions (*.PLIH and *.PLIM) for PL/I Source and Include file type to the "Content Types" association.
1. From the RDz workbench, click Window -> Preferences
2. In the field labeled "type filter text", begin typing the string "content" and observe where the filtering occurs with each key stroke
3. On the navigation view, select "Content Types" underneath the "General" category. The list of content types will be displayed in the main view
4. Scroll down and expand the list of source "Text" file types by clicking on the ">" sign next to "Text"
5. Scroll down the list of Text file associations and select "PL/I Source File"
6. On the bottom right corner of the view, click on the "Add" button to define a new Content Type association for *.PLIH
7. Click on "OK" to confirm the new file association
8. Next, add the file association for PL/I Include files. Expand the list of PL/I source file types by clicking on the ">" sign next to "PL/I Source File" and select "PL/I Include File"
9. On the bottom right corner of the view, click on the "Add" button to define a new Content Type association for *.PLIM
10. Click on "OK" to confirm the new file association
11. Lastly, commit the changes to workspace by clicking the "OK" button at the bottom of the Preferences window
Rational Developer for System z v9.0 was recently released. This release prevented users from be able to take advantage of our local help due to a known issue where the plugin "org.eclipse.jetty.webapp" is missing.
Symptoms: Users receive the following error message when they click on Test Connection "Connection Status: Failed
In the Rational Developer for System z (RDz) version 9.0, when you use the Secure Socket Layer (SSL) connection, you may see the following error while enabling your CICS debug configuration profile before debugging you CICS application:
PKIX path building failed: java.security.cert.CertPathBuilderException:
PKIXCertPathBuilderImpl could not build a valid CertPath.; internal cause is:
java.security.cert.CertPathValidatorException: The certificate issued by CN=RACF CA FOR HOST1 20160202, OU=NCIC, O=ABC is not trusted; internal cause is:java.security.cert.CertPathValidatorException: Certificate chaining error
where HOST1 is the z/OS host of your secure connection.
This error may be caused by the certificate not being set up correctly on the client machine.
In order to maintain your SSL connection with the correct certificate, please refer to Rational Developer for System z 9.0 documentation links below:
If you do not need to use certificates with your SSL connection, you can prevent the error by disabling the certificate management in RDz in the following way:
1. On the workbench menu bar click Window -> Preferences, then expand Explorer and click Certificate management.
2. Select the checkbox Disable certificate management for secure connections.
3. Click Apply and OK to save your settings and close the window.
Rational Developer for System z added the CARMA Enhanced Edit feature for CA Endevor SCM users in the 8.5.1 release. This CARMA Enhanced Edit feature is RDz's implementation of CA Endevor's Fast/Quick Edit. This feature allows RDz users to edit elements in the Endevor repository without having to retrieve/extract element out of repository into external file. When performing changes to a program, user will start by selecting the "version" of program/element within Endevor that they want to change. This usually is the "production" version of the program/element. When working with RDz CARMA, user would select (right-click on) element to be opened and select Edit/'Edit with' from the context menu.
When the CARMA Edit Element UI screen appears, user indicates to CARMA where they want element copied. This would typically be the "entry" environment/stage where they are allowed to edit element.
So what Endevor "actions" does CARMA use to copy "production" element into entry/editing environment/stage? That is a very important question because there are several different Endevor "actions" to do this, but not all RDz users are authorized to perform all Endevor "actions". The Endevor "actions" to handle this copy are generated from the RDz host Endevor RAM. These "actions" are run in foreground mode because of the unpredictable nature of running "action" as a batch job (CARMA has no idea when job will run/complete). Below I've listed how this "copy" of the element to "entry" environment/stage is handled in the available 8.5 releases and 9.0.
RDz 8.5.1 Endevor RAM: This was the initial implementation of the CARMA enhanced edit feature. In this release, the copy of the element to "entry" environment/stage is done using the Endevor GENERATE ELEMENT "action", with the "copyback" option. We have found that foreground GENERATEs are not allowed or are problematic in some customer environments.
RDz 22.214.171.124/9.0 Endevor RAM: In these releases, the copy to "entry" environment/stage was changed to use the Endevor TRANSFER ELEMENT "action". The element is opened in the RDz editor after the foreground Transfer has completed. In many cases, when the element is opened, some/all dependencies are not resolved until a GENERATE is done for the element being edited in this Environment/stage. We have also found that some customer sites do not allow RDz users to run Transfer "action".
RDz 126.96.36.199 Endevor RAM: In this release, the default way that CARMA handles this "copy" is still with the Endevor TRANSFER ELEMENT "action", however, we also allow you to configure RDz to use the RETRIEVE ELEMENT (from "prod") and ADD ELEMENT (to "test") "actions" to handle this "copy". To configure CARMA to use RETRIEVE-ADD "actions" for program/element "copy", you need to un-comment the 'ENTRY-STAGE-COPY-MODE = RETRIEVE-ADD' statement in the appropriate RDz CARMA CRACFG file. The CRACFG file is allocated in carma.endevor.conf (CRASTART servers) or CRASUBCA (CARMA batch servers).
To resolve dependencies when an element is opened using CARMA Enhanced Edit, a GENERATE ELEMENT request was added (188.8.131.52) following the TRANSFER/RETRIEVE-ADD "actions", however, this has again caused problems for customers that don't allow users to run foreground GENERATEs. An internal APAR has been opened to provide the 'Bypass generate processor' option on the Edit Element UI screen that appears when doing CARMA Enhanced Edit.
When you select this option, keep in mind there is good chance all dependencies will not be resolved by the RDz editor until a GENERATE is done on the element being opened, in the Endevor environment it is being opened from. This option should only be selected if you have trouble running foreground GENERATEs.
The current versions of RDz are 184.108.40.206 and 9.0 (Nov. 2013). The APAR mentioned in the previous paragraph will be delivered in the 8.5.1.next and 9.0.next RDz host PTFs. To verify what CA Endevor "actions" are being used in your environment, you can view the Endevor "actions" used in the MSG3FILE. The MSG3FILE is allocated in the user's CARMA server who performed the CARMA Enhanced Edit on element.
APAR PM96642 is fixed in Rational Developer for System z (RDz) v220.127.116.11 fixpack. This APAR picks up a fix from the Rational Common Licensing (RCL) product, and is not listed as one of the APARs fixed in that fixpack since it is an internal APAR.
The problem described in this APAR will occur if you are using a floating license with RDz, and the Rational Common licensing logger configuration file was not configured when RCL was first installed. The fix for this APAR will allow a restart of the RCL so that the configuration file will be read.
