IBM Integration Bus and Cloudant - Baby steps ...

June 11, 2018, 8:29 am

I'm starting to explore the possibilities of integration between IBM Integration Bus ( and thus IBM AppConnect Enterprise ) and IBM Cloudant, both of which are running on the IBM Cloud Platform ( nee Bluemix ).

Having spun up an instance of Cloudant, and worked out how to "feed" it using RESTful APIs, via cURL, I now wanted to find out how one can achieve integration between IIB and Cloudant.

This was of immense help: -

IBM Integration Bus v10 tutorials on Github


specifically this tutorial: -

Using a LoopBack Request node to insert data into a Cloudant database

and this: -

Using some of the more advanced features of the LoopBackRequest node


Tutorial: Installing LoopBack connectors


IIB V10.0.0.6 Loopback Request node using MongoDB and Cloudant tutorial


One of the key requirements is to install a Loopback Connector for IBM Cloudant, as per this exception: -

BIP2087E: Integration node 'TESTNODE_Dave' was unable to process the internal configuration message. 

The entire internal configuration message failed to be processed successfully. 

Use the messages following this message to determine the reasons for the failure. If the problem cannot be resolved after reviewing these messages, contact your IBM Support center. Enabling service trace may help determine the cause of the failure.
BIP4041E: Integration server 'default' received an administration request that encountered an exception. 

While attempting to process an administration request, an exception was encountered. No updates have been made to the configuration of the integration server. 

Review related error messages to determine why the administration request failed.
BIP3879E: The LoopBackRequest node received an error from LoopBack when attempting to connect to the data source name 'CLOUDANT'. Detail: ' WARNING: LoopBack connector "cloudant" is not installed as any of the following modules:   ./connectors/cloudant loopback-connector-cloudant  To fix, run:      npm install loopback-connector-cloudant --save '. 

An error was received when establishing the connection to the configured LoopBack connector data source. 

Check the error information to determine why the error occurred and take the appropriate action to resolve the error. The error detail is a LoopBack connector error message.
BIP2871I: The request made by user 'Dave-PC\Dave' to 'change' the resource '/LoopBack/Loopback_Cloudant' of type 'MessageFlow' on parent 'default' of type 'ExecutionGroup' has the status of 'FAILED'.

Having downloaded/installed NodeJS ( node-v8.11.2-x64.exe ) on the Windows VM, I tried/failed to work out how to resolve the missing dependency.

This gave me the clue: -




Preparing the Integration Node runtime environment to connect to Cloudant


Namely, I needed to navigate to the appropriate directory under the IIB Toolkit: -

cd C:\ProgramData\IBM\MQSI\node_modules

notepad C:\ProgramData\IBM\MQSI\package.json

{
  "name": "system32",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {
    "loopback-connector-cloudant": "^2.0.5"
  },
  "devDependencies": {},
  "scripts": {
    "test": "echo \"Error: no test specified\"&& exit 1"
  },
  "author": "",
  "license": "ISC"
}

npm install loopback-connector-cloudant --save

and, for good belt n' braces reasons, restart the Integration Node.

Once I did this, I was able to run the flow using the Flow Exerciser: -


and insert data into Cloudant using the Create operation: -


or retrieve data from Cloudant using the Retrieve operation: -


which is nice :-)

Final consideration, I needed to create a datasources.json configuration file here: -

C:\ProgramData\IBM\MQSI\connectors\loopback

{
"CLOUDANT":
{
"name": "bluey",
"connector": "cloudant",
"username": "2ha2294a-fd6f-42a5-a220-a4221ef51df0-bluemix",

Cloudant - Continuing to tinker

June 14, 2018, 7:54 am

I'm importing data from a Comma Separated Value (CSV) file into Cloudant, using the most excellent CouchDB tools provided by my IBM colleague, Glynn Bird.

Having created a CSV: -

vi cartoon.csv 

id,givenName,familyName
1,Maggie,Simpson
2,Lisa,Simpson
3,Bart,Simpson
4,Homer,Simpson
5,Fred,Flintstone
6,Wilma,Flintstone
7,Barney,Rubble
8,Betty,Rubble

( with due respect to the creators and owners of The Simpsons and The Flintstones )

I setup my environment: -

export ACCOUNT=0e5c777542c5e2cc2418013429e0824f-bluemix:d088ff753c9e258add92e45128cd161d
acbffedbcec0c8f78b216368ba0503ab

export HOST=d088ff753c9e258add92e45128cd161d-bluemix.cloudant.com

export COUCH_URL=https://$ACCOUNT@$HOST

export COUCH_DATABASE="CARTOON"

export COUCH_DATABASE=`echo $COUCH_DATABASE | tr '[:upper:]''[:lower:]'`

export COUCH_DELIMITER=","

and created my database: -

curl -X PUT $COUCH_URL/$COUCH_DATABASE

and populated it: -

cat $COUCH_DATABASE.csv | couchimport

This worked well but …. my data had a system-generated _id field whereas I wanted to use my own ID field: -

{
  "_id": "e143bcd25bc620e6aa8f2adc206cf21c",
  "_rev": "1-0152a3e6867ad34da6e882a80f0fbeff",
  "id": "1",
  "givenName": "Maggie",
  "familyName": "Simpson"
}

{
  "_id": "82c1068c830759a904cfdd02ab41b980",
  "_rev": "1-6bbb94301323a3c3f6ff54f1c3c765e5",
  "id": "2",
  "givenName": "Lisa",
  "familyName": "Simpson"
}

Thankfully Glenn kindly advised me how to use a JavaScript function to mitigate this: -

vi ~/transform_cartoon.js

var transform = function(doc) {
  doc._id = doc.id
  delete doc.id
  return doc
}

module.exports = transform

which effectively assigns the _id field to the value of the id field ( as taken from the CSV ) and also drops the original id field.

I dropped the DB: -

curl -X DELETE $COUCH_URL/$COUCH_DATABASE

and recreated it: -

curl -X PUT $COUCH_URL/$COUCH_DATABASE

and then repopulated it: -

cat $COUCH_DATABASE.csv | couchimport --transform ~/transform_cartoon.js

and now we have this: -

{
  "_id": "1",
  "_rev": "1-0e77dbadefba2a95e5cde5bda2ecd695",
  "givenName": "Maggie",
  "familyName": "Simpson"

}

{
  "_id": "2",
  "_rev": "1-fc746edc394ac98b013b7788cc1cca5d",
  "givenName": "Lisa",
  "familyName": "Simpson"
}

If needed, I could modify my transform: -

var transform = function(doc) {
  doc._id = doc.id
  return doc
}

module.exports = transform

to avoid dropping the original id field, to give me this: -

{
  "_id": "1",
  "_rev": "1-0152a3e6867ad34da6e882a80f0fbeff",
  "id": "1",
  "givenName": "Maggie",
  "familyName": "Simpson"
}

{
  "_id": "2",
  "_rev": "1-6bbb94301323a3c3f6ff54f1c3c765e5",
  "id": "2",
  "givenName": "Lisa",
  "familyName": "Simpson"
}

so I have choices :-)

macOS - Windows are off the screen ...

I had an issue earlier where my chosen Twitter client, Tweetbot, somehow wandered off the screen, lurking off to the right.

Whilst I could see Tweetbot when I hit the F4 key to open Mission Control, I couldn't actually get to it :-( 

Thankfully the internet ( what, all of it ? ) had the answer: -

…

OS X, particularly recent versions of the operating system, do a good job of corralling application windows by either not allowing a user to resize a window beyond the boundaries of the screen or by automatically snapping a window to a second display for those with multi-monitor setups. But sometimes — due to errors, bugs, or when disconnecting an external monitor — an application window can get "stuck" partially or completely outside of the visible area of the Mac's display, and getting it back can seem impossible. Thankfully, there's a quick and easy step you can take to automatically fix an off screen window in Mac OS X, and it's called Zoom.

…

If you can see the green zoom button, it's the best way to bring the missing portions of your OS X application window back into view. But what if it's the top of the window that's off screen, and you can't see the zoom button at all? In that case, you can achieve the same result via an option in the menu bar.

Simply select your desired application to make it active by click on its icon in the Dock (you should see the application's name in the top-left corner of your OS X Menu Bar, next to the Apple logo). Then, also in the Menu Bar, click the word Window and then Zoom. If you have multiple windows open in the same application, you can also select Zoom All to bring them all to the correct position at once.

…


Bottom line, I hit the Tweetbot icon in the Dock


and then chose Zoom from the Window menu


Now the app is back where it should be


Nice :-)

Cloudant - Backups

Having invested a fair bit of time populating databases into Cloudant: -


I wanted to backup my databases, for safety's sake.

My IBM colleague, Glynn Bird, came to the rescue again: -


with his couchbackup tool.

It was a simple matter of installing the package: -

sudo npm install -g couchbackup

and then running it: -

export COUCH_DB=acctdb
couchbackup --db $COUCH_DB > $COUCH_DB.txt

I then got really clever, and used some script to extract the names of ALL my databases: -

curl -X GET -g $COUCH_URL/_all_dbs

which returned a JSON object comprising the names of my DBs: -

["account","cartoon","foobar","snafu"]

so I "merely" needed to remove the square brackets, the double-quotes and the commas.

Long story short, this is with what I ended up: -

declare -a arr=(`curl -s -X GET -g $COUCH_URL/_all_dbs | sed 's/[][]//g' | sed 's/,/ /g' | sed 's/"//g'`)
for i in "${arr[@]}"; do export COUCH_DB=$i; couchbackup --db $COUCH_DB > $COUCH_DB.txt; done

This pulls back the list of databases from Cloudant, removes the unwanted characters, and then runs the couchbackup command to extract each of them to a text file ….

Nice :-)

This was recently published to the ODMDev space on IBM developerWorks: -


IBM ODM performance architects, Pierre-Andre Paumelle (paumelle@fr.ibm.com) and Nicolas Peulvast (peulvast@fr.ibm.com), have just released a new version of the IBM ODM Tuning Guide. The guide takes you on a tour of the key areas of IBM ODM and shows you how to get under the hood and improve the performance of ODM versions 8.9.0, 8.9.1, and 8.9.2.

The guide covers various "basic" and "advanced" topics, for example, you can learn how best to set up tracing in the Rule Execution Server, and you can find information on how to configure Solr on Decision Center. There is also help for you on migrating a Decision Server database, and how to optimize Decision Warehouse.

So roll up your sleeves, and get tuning. With this guide and a bit of elbow grease, you'll have ODM purring like a kitten in no time!

Using IBM App Connect enterprise capabilities with IBM MQ on Cloud

A requirement similar to this: -

Your company wants to expose a custom JSON-based REST API to their developers for sending messages to a stock control application through an MQ queue that is hosted in MQ on IBM Cloud. The format of the messages that the application expects is a custom COBOL copy book structure. An integration solution needs to be constructed that receives a simple JSON REST request, converts the JSON to the COBOL structure and then sends that to the correct queue. The integration solution is imported to run in IBM App Connect on IBM Cloud (with a plan that provides enterprise capabilities).

has come up recently, on a project upon which my team are engaged.

Therefore, this is rather useful_

Cloudant - Fun with Indexing and Querying

So I was trying to resolve an issue for a colleague, who needed to use an $or operator.

He found that his query would take a very long time ( minutes ) and fail to return any results, searching through ~500K documents.

I tested the problem and, eventually, the solution, using my own data set: -

id,givenName,familyName
1,Maggie,Simpson
2,Lisa,Simpson
3,Bart,Simpson
4,Homer,Simpson
5,Fred,Flintstone
6,Wilma,Flintstone
7,Barney,Rubble
8,Betty,Rubble

In Cloudant, each document looks like this: -

{
  "_id": "1",
  "_rev": "1-0152a3e6867ad34da6e882a80f0fbeff",
  "id": "1",
  "givenName": "Maggie",
  "familyName": "Simpson"
}

{
  "_id": "2",
  "_rev": "1-6bbb94301323a3c3f6ff54f1c3c765e5",
  "id": "2",
  "givenName": "Lisa",
  "familyName": "Simpson"
}

etc.

So this was the query I was using: -

{
  "selector": {
     "familyName": "Simpson",
     "givenName": {
        "$or": [
           {
              "givenName": "Maggie"
           },
           {
              "givenName": "Lisa"
           }
        ]
     }
  },
  "fields": [
     "givenName",
     "familyName"
  ],
  "sort": [
     {
        "givenName": "asc"
     }
  ]
}

In my simple brain, this would return documents for Maggie and Lisa, out of the eight in my database.

I'd previously created this index: -

{
   "index": {
      "fields": [
         "givenName"
      ]
   },
   "name": "givenName-json-index",
   "type": "json"
}

When I ran my query, I got nothing back: -


apart from this statistic: 


Thankfully I found a smart person on our Cloudant Slack channel, who told me where I was going wrong: -


So I changed my query: -

{
   "selector": {
      "$or": [
         {
            "givenName": "Maggie"
         },
         {
            "givenName": "Lisa"
         }
      ]
   },
   "fields": [
      "givenName",
      "familyName"
   ],
   "sort": [
      {
         "givenName": "asc"
      }
   ]
}

and now I see data: -


Yay!

Note to self - setting AND keeping alternate boot device on  macOS

Having added a shiny new 256 GB SSD drive to my  Mac Mini ( this is a USB3 device as I didn't fancy opening up the Mini and replacing the in-built Fusion drive ), I needed a way to make the drive bootable.

I'd already used SuperDuper to clone the old drive to the new drive.

I just needed to work out how to (a) boot from it and (b) make the new drive the main drive.

This gave me the answers: -


Specifically this: -


Note this subtlety: -


Yes, it's all very well booting from the SSD, but no good if it then reverts back to the "spinning rust" that is the Fusion drive ( yes, I know it's a mix of disk and SSD ).

However, the other issue that I faced was that my Bluetooth keyboard ( connected via an external USB Bluetooth dongle ) did NOT allow me to press [Option] during the boot process.

This came to the rescue: -


…
however, if you use Apple's Bluetooth keyboard, you could find that the system may ignore these inputs and boot normally. While you might assume that these options require a USB keyboard or other physical connection
…

Thankfully I had a wired USB keyboard, so I used that ….

The article does offer some other guidance: -

…
If any inputs are being sent via the Bluetooth keyboard before the controllers are active, then they will not be recognized by the system. However, if these inputs are performed after the controllers are activated, then they will be properly read. Therefore, for Bluetooth keyboards, be sure to press the desired key sequences after you hear the boot chimes and not before.
…

which is nice.

So I'm now booting from USB/SSD and the 2014 Mac Mini is suddenly WAY faster !

This just in: -

IBM API Connect V2018.3.1 is now available. This update includes important internal development fixes and support for the API Designer as part of the toolkit.

Content

IBM API Connect 2018.x delivers enhanced capabilities for the market-leading IBM API management solution. In addition to the ability to deploy in complex, multi-cloud topologies, this version provides enhanced experiences for developers and cloud administrators at organizations.

The API Connect 2018.3.1 update includes important internal development fixes. In addition, this release includes the API Designer within the toolkit. API developers use the API management functions in the API Designer or the CLI to create draft API definitions for REST and SOAP APIs, or for OAuth provider endpoints that are used for OAuth 2.0 authentication. The API definitions can be configured to add the API to a Product, add a policy assembly flow (to manipulate requests/responses), and to define security options and other settings. APIs can then be tested locally prior to publishing, to ensure they are defined and implemented correctly.

Upgrading to 2018.3.1 makes changes to the underlying data structure of API Connect.  It is highly recommended to have automatic backups configured in your environment and at least one successful backup complete prior to performing this upgrade.

We advise all users of IBM API Connect 2018.1.x and earlier versions of IBM API Connect 2018.2.x to install this update to take advantage of the fixes.

IBM AppConnect and DB2 and SQL0530N

I'm fiddling about with IBM AppConnect Professional ( formerly known as CastIron ), looking at the integration between a flow running on AppConnect, hosted on the IBM Cloud ( nee Bluemix ) and a DB2 database running on a VM on my Mac.

I'll be writing another blog post about the actual integration, including the Secure Gateway later.

Meantime, I wanted to test my flow, which should be monitoring a table for changes.

I did this by inserting a new row into the EMPLOYEE table of the SAMPLE database ( which has been around since I worked on DB2/400 in the mid-90s ).

This is what that table looks like: -

db2 describe "select * from DB2INST1.EMPLOYEE"

This is what I ran: -

which returned: -

DB21034E  The command was processed as an SQL statement because it was not a 
valid Command Line Processor command.  During SQL processing it returned:
SQL0530N  The insert or update value of the FOREIGN KEY 
"DB2INST1.EMPLOYEE.RED" is not equal to any value of the parent key of the 
parent table.  SQLSTATE=23503

which baffled me somewhat.

I dug into the database further: -

db2look -d sample -e -t db2inst1.employee

…

I then saw this: -

…
  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=bpm.uk.ibm.com)(PORT=1521)))

whereas the BPM -> Oracle connectivity needs to know / care about the Oracle Service Name: -

We had a requirement to generate some test data within a Microsoft Excel spreadsheet.

similar to this: -


This was the magic invocation: -

="Subscriber Reference #"&ROW()

We merely needed to copy that to the clipboard, and paste it into a nice chunk 'o cells ….

So it's a piece of text concatenated with the row() index, using the ampersand ( & ) symbol.

Learning something new every day .... Where's my WAS Admin Console stuff for BPM ?

July 18, 2018, 5:08 am

So today I'm working with a client to deploy IBM BPM Standard 8.6 alongside IBM Master Data Management 11.6, to leverage the Data Stewardship capabilities that the BPM/MDM tie-up offers.

In brief, this means that I'm installing the BPM binaries into an existing installation of WebSphere Application Server Network Deployment 8.5.5.13, which is hosting the MDM environment ( Deployment Manager, Node Agent and Application Server/Cluster ).

However, when I created the BPM Deployment Environment, using BPMConfig.sh, I'm specifying to use DIFFERENT WAS profiles, leaving the MDM stuff well alone.

So, for no obvious reason, I hit a small glitch with my Deployment Manager, having built the BPM Deployment Environment.

Whilst I can start/stop things, run up the Process Center/Portal/Admin UIs etc., I'm unable to see  the BPM-related capabilities within the Deployment Manager ( Integrated Solutions Console ), such as: -




etc. even though the ISC *DID* show BPM as being installed : -


( ignore the version in this example; I've got 8.5.6 on my VM, but 8.6.0 on the customer's environment )

I also checked that the profile was properly augmented: -

cat /opt/ibm/WebSphere/AppServer/properties/profileRegistry.xml
 
<?xml version="1.0" encoding="UTF-8"?><profiles>
    <profile isAReservationTicket="false" isDefault="true" name="Dmgr01" path="/opt/ibm/WebSphereProfiles/Dmgr01" template="/opt/ibm/WebSphere/AppServer/profileTemplates/management">
        <augmentor template="/opt/ibm/WebSphere/AppServer/profileTemplates/BPM/BpmDmgr"/>
    </profile>
    <profile isAReservationTicket="false" isDefault="false" name="AppSrv01" path="/opt/ibm/WebSphereProfiles/AppSrv01" template="/opt/ibm/WebSphere/AppServer/profileTemplates/managed">
        <augmentor template="/opt/ibm/WebSphere/AppServer/profileTemplates/BPM/BpmNode"/>
    </profile>

but to no avail.

More weird, I received something similar to this: -

ServletWrappe E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0014E: Uncaught service() exception root cause /com.ibm.ws.console.servermanagement/addPropLayout.jsp: com.ibm.websphere.servlet.error.ServletErrorReport: javax.servlet.jsp.JspException: Missing message for key "addprops.category.label.businessintegration"

when I attempted to navigate here: -


and the right-hand side of the page merely contained that exception.

Thankfully this post had the answer: -


specifically this bit: -

…
3) run the command to restore admin console application: [Dmgr profile]/bin/iscdeploy.sh -restore
...

So I did the needful: -

/opt/ibm/WebSphereProfiles/Dmgr01/bin/iscdeploy.sh 

having shut down ALL the JVMs, and magically it fixed the problem.

I'm not sure how I got here, but glad I found a fix.

Thanks, Internet, you rock !

WebSphere Application Server - Testing JDBC connections via Jython and the EJBTimer

July 23, 2018, 5:28 am

As part of a recent engagement, I'd written a simple Jython script to test WAS -> database connections: -

cellID = AdminControl.getCell()
cell=AdminConfig.getid( '/Cell:'+cellID+'/')
for dataSource in AdminConfig.list('DataSource',cell).splitlines():
 print dataSource
 AdminControl.testConnection(dataSource)

However, when I ran this against an IBM Business Process Manager Standard 8.6 environment, I saw this: -

DefaultEJBTimerDataSource(cells/PCCell1/applications/commsvc.ear/deployments/commsvc|resources.xml#DataSource_1228749623069)
WASX7017E: Exception received while running file "/mnt/Scripts/testDataSource.jy"; exception information: com.ibm.websphere.management.exception.AdminException
javax.management.MBeanException
java.sql.SQLException: java.sql.SQLException: Database '/opt/ibm/WebSphereProfiles/AppSrv01/databases/EJBTimers/AppClusterMember1/EJBTimerDB' not found. DSRA0010E: SQL State = XJ004, Error Code = 40,000

which was an annoyance, as I'm not actively using the EJBTimer datasource.

As ever, the solution was simple, rather than testing ALL datasources within the cell, I changed the script to only test the datasources that are specifically part of the BPM Deployment Environment i.e. those that are scoped at cluster level.

cellID = AdminControl.getCell()

cell=AdminConfig.getid( '/Cell:'+cellID+'/')
cluster=AdminConfig.getid("/ServerCluster:AppCluster/")
for dataSource in AdminConfig.list('DataSource',cluster).splitlines():
 print dataSource
 AdminControl.testConnection(dataSource)

cluster=AdminConfig.getid("/ServerCluster:AppCluster/")
for dataSource in AdminConfig.list('DataSource',cluster).splitlines():
 print dataSource
 AdminControl.testConnection(dataSource)

cluster=AdminConfig.getid("/ServerCluster:AppCluster/")
for dataSource in AdminConfig.list('DataSource',cluster).splitlines():
 print dataSource
 AdminControl.testConnection(dataSource)

For a BPM Standard environment, this is good enough………

Also, for the record, it's possible to see the EJBTimer datasources within the WAS Integrated Solutions Console: -




which is nice.

DB2 - Moving databases

This is definitely a Your Mileage May Vary (YMMV) post.

If in doubt, please check with IBM Support *BEFORE* following the steps outlined here …

So I had a requirement to rename some IBM BPM databases from their default names of BPMDB, CMNDB and PDWDB.

This is related to IBM BPM 8.6 on DB2 v11.1.2.2 although the same approach works for DB2 v10.5 as well.

Thankfully DB2 comes with a useful db2relocate tool, as described here:-


So, before doing this for real, I wanted to test it using the SAMPLE database.

This is what I did ….

Switch to the instance owner

su - db2inst1

Create the SAMPLE database

 db2sampl 

  Creating database "SAMPLE"...
  Connecting to database "SAMPLE"...
  Creating tables and data in schema "DB2INST1"...
  Creating tables with XML columns and XML data in schema "DB2INST1"...

  'db2sampl' processing complete.

Validate the current catalog

db2 list db directory

 System Database Directory

 Number of entries in the directory = 4
…
Database 4 entry:

 Database alias                       = SAMPLE
 Database name                        = SAMPLE
 Local database directory             = /home/db2inst1
 Database release level               = 14.00
 Comment                              =
 Directory entry type                 = Indirect
 Catalog database partition number    = 0
 Alternate server hostname            =
 Alternate server port number         =

Validate the current DB storage

ls -al /home/db2inst1/db2inst1/NODE0000/SAMPLE

DB20000I  The TERMINATE command completed successfully.

Create a template configuration file

This defines the FROM and TO states

vi sample.cfg

DB_NAME=SAMPLE,SAMPLENE
DB_PATH=/home/db2inst1
INSTANCE=db2inst1

Move the database from the old container to the new container

Note that this works for me because my database has a single partition, and is located in the instance owner's home directory
- This is where YOUR mileage MAY/WILL vary

mv /home/db2inst1/db2inst1/NODE0000/SAMPLE /home/db2inst1/db2inst1/NODE0000/SAMPLENE

Validate the new DB storage layout

 ls -al /home/db2inst1/db2inst1/NODE0000/SAMPLENE/
