This article feels like I should have written years ago. As it is, I haven't, but let's do it anyway.

A few weeks ago a (somewhat older) question on community.oracle.com caught my attention. It was about how to do logging in Oracle SOA Suite. 

This very much possible, and it can be simply done using an Embedded Java activity. However, if you want to have multiple loggings in a larger BPEL process, or have multiple BPEL components in a composite with multiple loggings scattered all over them, then Embedded Java activities aren't that practical.

So, I have developed a bit more sophisticated solution. For just one logging, it is a bit overdone, but I find it more practical with multiple loggings.

It starts with a quite simple Log wrapper class, that I added to GitHub. It is a wrapper around Java Util Logging, and helps with instantiating with a Logger instance. One of the constructors takes in a compositeName and componentName:

public class Log {
    private static final String BASE_PACKAGE="oracle.soa.bpel";
    private static Logger log;
    private String className;
...
    public Log(Class loggingClass) {
        super();
        setClassName(loggingClass.getName());
        log = Logger.getLogger(getClassName());
    }
    
    public Log(String loggingClass) {
        super();
        setClassName(loggingClass);
        log = Logger.getLogger(getClassName());
    }

    public Log(String compositeName, String componentName) {
        super();
        String loggingClass = BASE_PACKAGE+"."+compositeName+"."+componentName;             
        setClassName(loggingClass);
        log = Logger.getLogger(getClassName());
    }

An important aspect here is the static variable BASE_PACKAGE which is set to "oracle.soa.bpel". Which I'll get back to in a minute. The constructor uses this, and the compositeName and compentName to build up a sort of className, that it prefixes with the BASE_PACKAGE.

It also has some logging methods, that requires a methodName, that it uses as an extra identifier for the logging, added to the full class Name.

This class I 'deployed' to a jar file. This makes it reusable in multiple composites, while the source is versioned only once.

 Add it to the SCA_INF/lib folder of your composite:

After running Ant in that folder, you should restart the server. The Ant script will add all the jar files in that folder, including yours, to the manifest file of the oracle.soa.ext.jar file in that folder. Doing so, it will be appended to the Classpath of SOA Suite.

To use this in your BPEL, it is important to add the following line at the beginning:

<import location="nl.darwinit.soautils.logging.Log" importType="http://schemas.oracle.com/bpel/extension/java"/>

Like this:

Having done that you can use the Log class in the Embbeded Java activity. To begin with, I find it usefull to add an Embedded Java to a scope which contains simple xsd:string based variables. Using an Assign you can easily assing proper values to the local variables:

The compositeName and componentName variables can be filled with ora:getCompositeName() and ora:getComponentName() respectively. Doing so makes it easier to access these values in an Embedded Java activity. The Java snippet Embedded Java in my example project is:

String compositeName = (String) getVariableData("compositeName");      
String componentName = (String) getVariableData("componentName");      
String text = (String) getVariableData("text");      
String methodName= (String) getVariableData("methodName");      
Log log = new Log(compositeName,componentName);     
  
String message="**** BPEL "+methodName +" " + text +" ****";    
log.info(methodName, message);    
addAuditTrailEntry(message);

The addAuditTrailEntry() shown in this snippet is an API that adds the message to the flowtrace also:

Earlier I mentioned the BASE_PACKAGE variable in the Log class. This refers to the oracle.soa.bpel log-appender. This can be configured in the soa-infra Log Configuration:

And then:

You could add a custom Logger, but it is easier to use an existing one. And to me it makes sense to use the oracle.soa.bpel Logger. If you would choose to use another logger, you would need to change the BASE_PACKAGE variable in the class.

Make sure it has a severity or Log Level low enough to cater for your logging. Set it to the Runtime Logger, but for persistence purpose you probably would need to add it to the "Loggers with Persistent Log Level State". For changing the Runtime logger, you would not need to restart the server. You do need to make sure that the "minimum severity to log" on the server in the WebLogic console.

Before you test, it can be handy to "tail" the diagnostic log as follows:

[oracle@ol7vm logs]$ tail -f DefaultServer-diagnostic.log |grep oracle.soa.bpel

I added my Demo BPEL process also to GitHub. If you test it, the output will be as follows:

So that works! Easy, right?

Now, this works for one simple Log in a BPEL process. But what about if you want to trace the flow using multiple Logs. And maybe even, in fault handlers log particular errors. The scope I introduced can be converted to a subProcess:

The scope is replaced with a call activity, that can be renamed. The scope variables now function as call arguments:

You can copy&paste this and rename it to reflect for instance a LogEnd activity:

Testing this, gives the following output:

As can be seen, now a simple log is done using a simple call activity. In this example the Log subprocess is within the same BPEL process, so you could move the setting of the componentName and compositeName variables in an assign in the subProcess, re-enstating the original assign.

However, you could of course move the Embedded Subprocess to a Reusable Subprocess. And then it might be usefull to be able to provide at least the componentName as an argument.

I think it is not so useful to put it in a separate BPEL process that can be called from external composites. In that case you would need to do an invoke with an accompanying assign and variable declarations for each Logging. So I would prefer to define either an embedded or a reusable subprocess for each composite/bpel that you want to do logging in.

Although I experience this article a few years late, I hope it does help.

Last year I wrote about how I created a seemless desktop using Vagrant, VirtualBox en MobaXterm.

This week I was busy creating a new box with Oracle Linux, later switching to CentOS and installing several IDE's in it. And Docker.

Next week a big change is due for me. And for that I'll be going to switch laptops. Also others will going to use my vagrant project. Up till now I used local file based boxes. So if you wanted to use my projects that I posted on GitHub, you had not only to have the install binaries in a certain folder structure, but also the particular box downloaded in the particular boxes folder. 

This morning I decided to figure out how to publish them on the Vagrant cloud. And it is surprisingly easy, of course! Why I didn't do that before? Well, actually, I started with this by preparing a workshop for colleagues. And to simultaneously download the same box by every participant, did not seem a good idea. So I distributed the vagrant project with all the installers including the box on a stick.

But now, preparing for my laptop switch and distributing it for my colleagues, it seems a good idea.

I found this step by step article that guided me through the process. But let me go through the process my self.

First you'll need an account on the Vagrant Cloud. You can get there from the main page of vagrantup.com. And then click on the Find Boxes button:

 

Create a new account or login, if not already done that.

You'll land on the Search page:

There click the "New Vagrant Box" button:

Provide a version, it's smart to start with 1 (it will check it), and possibly a description. Although I find a good base description important, I'm not sure what to write on a first version as a description. For subsequent versions, it seems a good to fill in as well. Like with GitHub/Subversion commit messages.

 Within the version, I was looking for an upload button, but you first get to define a provider. So click on the provider button:

I want to upload to the Vagrant Cloud, so the default will suffice. Click on the Continue to upload button:

Using the Browse button, browse to your Vagrant box and have it upload it.

Now, to be able to use the box, and others to discover your box, you'll need to release it. So go to the versions sub tab, and click on the Release button for the v1 version:

Now my boxes are searchable:

To use a box, you can create a Vagrant file with the following reference to the box:

Or create a new box in a new folder using a command like vagrant init makker/CO78SwGUI --box-version 1, continued by vagrant up:

d:\Projects\vagrant\co78>vagrant init makker/CO78SwGUI --box-version 1
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

d:\Projects\vagrant\co78>vagrant up

You can list boxes with the (sub)command vagrant box list:

d:\Projects\vagrant\co78>vagrant box list

makker/ol77SwGUIv1.1 (virtualbox, 1)

Remove a box with vagrant box remove CO77GUIv1.1:

d:\Projects\vagrant\co78>vagrant box remove CO77GUIv1.1
Box 'CO77GUIv1.1' (v0) with provider 'virtualbox' appears
to still be in use by at least one Vagrant environment. Removing
the box could corrupt the environment. We recommend destroying
these environments first:

rhfuse (ID: ca219fa1fe0b4984bf77aa7807c0feb2)

Are you sure you want to remove this box? [y/N] y
Removing box 'CO77GUIv1.1' (v0) with provider 'virtualbox'...

But you can add the freshly created box also using the vagrant box add command:

d:\Projects\vagrant\co78>vagrant box add makker/CO78SwGUI --box-version 1
==> box: Loading metadata for box 'makker/CO78SwGUI'
    box: URL: https://vagrantcloud.com/makker/CO78SwGUI
==> box: Adding box 'makker/CO78SwGUI' (v1) for provider: virtualbox
    box: Downloading: https://vagrantcloud.com/makker/boxes/CO78SwGUI/versions/1/providers/virtualbox.box

Download redirected to host: vagrantcloud-files-production.s3.amazonaws.com
Progress: 3% (Rate: 10.5M/s, Estimated time remaining: 0:03:29)

As can be seen it mentions that it started the download earlier, but I broke it off. It apparently resumes the download.

My current Vagrantfiles have the following declaration of the vagrant box:

...
BOX_NAME="CO78GUIv1.1"
BOX_URL="file://../boxes/CO78SwGUIv1.0.box"
VM_MEMORY = 12288 # 12*1024 MB
...
Vagrant.configure("2") do |config|
  # The most common configuration options are documented and commented below.
  # For a complete reference, please see the online documentation at
  # https://docs.vagrantup.com.

  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://vagrantcloud.com/search.
  config.vm.box=BOX_NAME
  config.vm.box_url=BOX_URL
  config.vm.hostname=VM_HOST_NAME
  config.vm.define VM_MACHINE
  config.vm.provider :virtualbox do |vb|
    vb.name=VM_NAME
    vb.gui=VM_GUI
    vb.memory=VM_MEMORY
    vb.cpus=VM_CPUS
...

Based on the suggestion of the Vagrant Cloud:

I adapted this as follows:

...
BOX_NAME="makker/CO78SwGUI"
BOX_VERSION = "1"
#BOX_URL="file://../boxes/CO78SwGUIv1.0.box"
VM_MEMORY = 12288 # 12*1024 MB
...
Vagrant.configure("2") do |config|
  # The most common configuration options are documented and commented below.
  # For a complete reference, please see the online documentation at
  # https://docs.vagrantup.com.

  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://vagrantcloud.com/search.
  config.vm.box = BOX_NAME
  config.vm.box_version = BOX_VERSION
  # config.vm.box_url=BOX_URL
  config.vm.hostname=VM_HOST_NAME
  config.vm.define VM_MACHINE
  config.vm.provider :virtualbox do |vb|
    vb.name=VM_NAME
    vb.gui=VM_GUI
    vb.memory=VM_MEMORY
  vb.cpus=VM_CPUS
...

I uncommented the BOX_URL variable with the config.vm.box_url lines. And added the BOX_VERSION and config.vm.box_version lines. Most importantly I changed the BOX_NAME variable to makker/CO78SwGUI.

These suggestions will download my Cloud boxes without me needing to distributed them separately.

Happy Upping!

Last week I provided a script to automatically install the SOA or BPM Quickstart.

Today, below I'll provide a script to install SQL Developer on Windows. I always use the "zip-with-no-jre" file. Therefor installing it is simply unzipping it.

For unzipping, I use the java jar tool This is convenient, because if you want use SQL Developer you need a JDK (unless you choose to use the installer with jre). And if you have a jdk, you have the jar tool. The script mentioned in the previous article, takes care of installing java. So, if you want to do that as well, you could add it to this script.

One disadvantage of the jar  tool is that it can't unzip to a certain folder other than the current folder. So you have to CD to the folder into which you want to unzip it. The script therefor saves the current folder, and CD's to the unzip folder. After installation it CD's back.

The script unzips into the a subfolder, under C:\Oracle\SQLDeveloper. I like to keep my Oracle IDE's together, but grouped. Within the zip file there is a sqldeveloper folder, which is renamed to the name of the zip.

With SQLDeveloper 20.2 I found that it required the msvcr100.dll in the $JDK\jre\bin folder. Apparently in the latest JDK 8 update (261), that I used when creating this script, it wasn't. I found it in c:\Windows\System32 on my system, so I copied it from there to the $JDK\jre\bin folder. But a colleague didn't find it.

Another step in the script is that it copies the a copy of the UserSnippets.xml file. At my customer I created several handy maintenance queries that I saved as snippets. When you do so, you find those saved into the UserSnippets.xml file in the %USERPROFILE%\AppData\Roaming\SQL Developer. Where the %USERPROFILE% usually points to the C:\users\%{your windows username} folder.

If you want to share a copy of that to the users installing the tool using this script, you can save it in the same folder as this script. We keep it in SVN.

Several customer projects further and iterations on the script further, I revised this script lately again. Because I'm leaving this customer in a week or three, and to help my successors to build up their development pc's in a comfortable and standard way.

You may have noticed that over the years I've grown fond of scripting stuff, especially building up environments. At my current customer every developer installed the several IDE's, test tooling and TortoiseSVN by hand. So every one has the tooling in another folder structure. Checked out the subversion repo's by hand and therefor in another structure. 

So, scripting things help in having the tooling in the same folder structure for every one. And that reduces the chances on problems and misconfigurations. Especially preventing the infamous phrase: 'It works with me...' when having problems.

One of the revisions is to have nested if-else structures in the script, which makes it more readable then the conditional goto's we were used to use in Windows .bat files.

Another important improvement was to have the install binaries in a separate fileserver-repository. This makes it possible to have the scripting and depending files in a Subversion repository.

The script improved installSoaQS.bat is as follows:

• I use 8.2 which is the latest-greatest at the moment.
  
• For my Vagrant projects I want a base box with the Server with GUI topology. So I used that, which was actually the default in the wizard.
• I use a NAT network adapter, for my Vagrant projects, so I skipped the network setting Tim Hall mentions.

Now, I use this as a base box for my Vagrant projects, and therefor I don't do this installation on a dayly basis. I have a Oracle Linux 7.7 box, and haven't had much problems with it.

However, I did had troubles with installing the Guest Additions this time. It didn't have the kernel-devel and kernel-header packages installed. Which is quite normal, so I did it using yum. However I kept getting the anoying mesasge that it couldn't get the 5.4.17-2011.5.3.el8uek.x86_64 version of the kernel headers. And the Guest Additions still wouldn't install. 

It kept me busy for some time, until I realized that by default it starts with the 5.4.x UEK kernel, while I it could install the kernel packages and headers for the 4.18.0.x  version.

So I found out how to startup with the correct kernel (correct in the sense that it is the kernel that allows me to use the GuestAdditions...). This can be done as follows:

sudo grubby --info=ALL

sudo ls /boot//vmlinuz-*
/boot//vmlinuz-0-rescue-fddb3eeab19e4a928d6bfa04e0f91830
/boot//vmlinuz-4.18.0-193.14.3.el8_2.x86_64
/boot//vmlinuz-4.18.0-193.el8.x86_64
/boot//vmlinuz-5.4.17-2011.5.3.el8uek.x86_64

sudo grubby --set-default /boot/vmlinuz-4.18.0-193.14.3.el8_2.x86_64

sudo dnf install kernel-devel kernel-headers gcc make perl

Next stop: boxing it into a Vagrant box.

At my current customer we use JMS queues that are implemented with AQ queues based on sys.aq$_jms_text_message. In Weblogic you can create a so-called Foreign server that is able to interact with these queues over a datasource. For a Weblogic application, like SOA Suite or OSB, it is as if it is a regular Weblogic JMS queue. Pretty smart, because unlike a JDBC based Weblogic JMS Server, you can not only use the sys.aq$_jms_text_message type to query the aq table, as I described earlier. Not only that, you can also use the AQ PL/Sql api's to enqueue and dequeue these messages.

This can come in handy when you need to purge the tables, to remove the expired messages. But this morning there was a hickup in OSB, so that it couldn't process these messages succesfully. Because of the persisting rollbacks the messages are moved to the exception queue by AQ with the reason 'MAX_RETRY_EXCEEDED'. After I investigated the issue and some interaction with our admins the OSB was restarted which solved the problem.

But the earlier expired messages were still in the exception queue and processes were waiting for the response. So I thought it would be fun to have my own script to re-enqueue the expired messages. 

Although the admins turned out to have scripts for this, I would like to have my own. Theirs maybe smarter or at least they had more time to develop.

This script is at least publishable and might be a good starting point if you have to do something with AQ.

This script starts with a cursor that is based on the query described in the post mentioned above. It selects only the Expired messages, where the root-tag starts with a concatenation of '<' and the message type declared in the top. If there was a JMS type you could also select on the userdata.header.type attribute.

It logs a few attributes, merely for me to check if the base of the script worked, without the dequeue and the enqueue. The selecting of the particular JMS properties are taken from the earlier script and are an example on properties that you could use to more granularly determine if a message is eligable to be re-enqueued.

The found message is enqueued and then dequeued, both with visibility set to on_commit. This ensures that the enqueue and dequeue is done within the same transaction. You should hit the commit button in SQL Developer (or your other favorite Database IDE).

The from clause construct:

      from (
        select 'DWN_OUTBOUND_TABLE' queue_table
        , qtb.* 
        from AQ$DWN_OUTBOUND_TABLE qtb
      ) qtb

is from a script I created at the customer to query over all the available queue tables, by doing a union-all over all the queue-tables. That's why the first column names the queue table that is source for the record. 

This script can be made more dynamic by putting it in a package and make a pipelined function for the query, so that you can provide the queuetable to query from as a parameter. You could even loop over all the user_queue_tables to dynamically select all the message from all the tables without having to do union alls over the familiar queue tables. See my Object Oriented Pl/Sql article for more info and inspiration.

You might even have fun with Polymorphic Table Functions, the Patrick-ACE-Director-Bar-solutions is expert on that.

CorrelationSets in BPEL are as old as the road to Rome. I wrote about it before: 

• PCS and Correlations: the next big thing cavemen already used...
• Use of correlation sets in SOA Suite

Although it was in the BPEL project from the very beginning, when Oracle acquired it in 2004, you might not have dealt with it before. But maybe not even realized that you can use it in Oracle Integration Cloud, with structured processes.

In the first week of june I got to do a presentation about this subject, in a series of Virtual Meetups.

If you weren't able to attend, but would like to watch it then you're in luck, it got recorded by Phil Wilkins:

In my presentation I start with a simple demo based on a BPEL process. I have put the resulting code on GitHub: https://github.com/makker-nl/blog/tree/master/CorrelationDemo. 

Then I move on to a more complicated situation in OIC. I created an export for that project and placed it on GitHub too: https://github.com/makker-nl/blog/tree/master/CorrelationDemoOIC

This allows you to inspect it and try to recreate it yourself.

My sincere appologies for this late sharing.
