How to monitor an IBM Business Process Manager environment using WebSphere Application Server Performance Tuning Toolkit

How to monitor an IBM Business Process Manager environment using WebSphere Application Server Performance Tuning Toolkit

The WebSphere Application Server Performance Tuning Toolkit (PTT) is an Eclipse-based intelligent tool that is designed to help users tune the performance of WebSphere Application Server using data collection, data analysis, and statistical inference technology. It is designed to help users locate the bottlenecks and tune their applications appropriately. Through JavaTM Management Extensions (JMX), the toolkit collects performance data from the Performance Monitoring Interface (PMI) of WebSphere Application Server and gives you an easily understood picture with some charts and forms to locate the bottleneck and tune them appropriately.

IBM BPM 8.5.5 - Performance Admin Console - Computer says "No"

So you're trying to access the IBM BPM 8.5.5 Business Performance Admin Console: -


but the computer says "No"

Either the user name or password is wrong, or you are not authorized to log in to the Performance Admin Console.


Now we know that the Performance Admin Console runs on the Support cluster: -


So let's see what's running: -


and then let's look at the User RunAs roles: -


So there's the answer ....

By default, the Deployment Environment admin user - deadmin ( in my case ) - is mapped to the tw-loader role

Once we log in using deadmin all is good: -


which is nice.

IBM Notes - Finding my temporary files

So one of my colleagues sent me an Excel spreadsheet as an attachment - once I'd finished dressing him down about (a) using MS Office and (b) sending email attachments, I double-clicked on the .XLS file, opened it up in OpenOffice, and then edited it - and then saved it ( note, I said Save, not Save As ).

You know what's coming ?

Yes, I'd saved the file to some random location on my hard-disk, and couldn't find it to send it back to my colleague - via Connections Files, of course.

Thankfully, I did not re-open the file, so I didn't overwrite my changes .....

But where is the spreadsheet ???

I opened up a command prompt ( Terminal on the Mac ), and went a-huntin'

$ cd /
$ find / -name jam*.xls 

...
find: /private/var/db/launchd.db/com.apple.launchd.peruser.97: Permission denied
find: /private/var/db/locationd: Permission denied
find: /private/var/db/Spotlight: Permission denied
find: /private/var/db/sudo: Permission denied
/private/var/folders/8t/s52kgwtj4l16sp3nf0tl7f9c0000gn/T/TemporaryItems/notes/jamsurvey.xls

find: /private/var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/Cleanup At Startup: Permission denied
...

This allowed me to "rescue" the file: -

$ cd Desktop/
$ cp /private/var/folders/8t/s52kgwtj4l16sp3nf0tl7f9c0000gn/T/TemporaryItems/notes/jamsurvey.xls .

Sorted :-)

IBM Business Monitor 8.5.5 - My First Installation ....

.... failed rather spectacularly, mainly because I didn't read the manual :-)

So BAM 8.5.5 has a different approach to creating the configuration, rather than the previous 8.0.1.2 installation, which used the IBM BPM Deployment Environment process.

So I installed the binaries: -

com.ibm.cic.agent_1.7.2000.20140227_0303
com.ibm.websphere.MON.v85_8.5.5000.20140530_1037
com.ibm.websphere.ND.v85_8.5.5002.20140408_1947
com.ibm.ws.cognos.v1021.linuxia64_10.2.1.20140530_2310

and then configured the clusters using the new scripted process: -

cd /opt/IBM/WebSphere/AppServer/scripts.wbm/monConfig
./monConfig.sh -c ~/monconfig_threeCluster.properties -d Dmgr01 -p passw0rd -u wasadmin

and then tried to start the clusters, one of which ( the Support cluster, which hosts Cognos ) failed with: -

[29/07/14 17:21:22:589 BST] 00000001 VariableExpan E   WSVR0244E: An undefined i.wbmCognosUrl product variable has been encountered in the value property of the /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/config/cells/bam855Cell/resources.xml#J2EEResourceProperty_1406649536784 configuration object.
[29/07/14 17:21:22:591 BST] 00000001 ResourceMgrIm E   WSVR0017E: Error encountered binding the J2EE resource, CognosEndpoint, as resource/wbm/CognosEndpoint from /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/config/cells/bam855Cell/resources.xml
com.ibm.wsspi.runtime.variable.UndefinedVariableException: Undefined variable i.wbmCognosUrl

So I checked the resources.xml file: -

view /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/config/cells/bam855Cell/resources.xml

which showed: -

...
      <resourceProperties xmi:id="J2EEResourceProperty_1406649536784" name="{com.ibm.cognos}cognosServiceRootId.url" type="java.lang.String" value="${i.wbmCognosUrl}" description="Cognos end point setting" required="false"/>
...

The offending value actually comes from one of two files: -

/opt/IBM/WebSphere/AppServer/profiles/Dmgr01/config.wbm/MonitorProfileVals.py

...
wbmCognosUrl = "${i.wbmCognosUrl}"
...

/opt/IBM/WebSphere/AppServer/profiles/Dmgr01/config.wbm/MonitorProfileVals.ant

...
wbmCognosUrl = $@i.wbmCognosUrl@
...

The root cause ?

(a) I did not read the manual
(b) I had not actually deployed / configured Cognos to the Support cluster :-)

The latter part of the solution is to actually run a script to deploy Cognos.

Here's an EXAMPLE from my own environment: -

/opt/IBM/WebSphere/AppServer/profiles/Dmgr01/bin/wsadmin.sh -lang jython -user wasadmin -password passw0rd

AdminTask.wbmDeployCognosService('[-cluster monSupportCluster1 -dbName COGNOSCS -dbUserName cognos -dbUserPassword passw0rd -adminUserName wasadmin -adminPassword passw0rd]')
AdminConfig.save()
AdminNodeManagement.syncActiveNodes()
quit

Once I did this, the Support cluster came up nicely :-)

IBM BPM 8.5.5 - What goes where ?

Or, to be more precise, what applications sit on what cluster ?

Note that, in BPM 8.5.X, we only have three clusters; the old WebApp cluster has been morphed into the AppCluster, meaning that the need to "jump" across the cell via a load-balancer has gone away .....

This is what I've discovered thus far: -

AppCluster

Process Center

Process Admin

Process Portal


BPC Explorer

https://rhel6.uk.ibm.com:9445/bpc

MECluster

Nowt but the Messaging Engine :-)

Note that in BPM 8.5.X, we only have a single Service Integration Bus ( SIbus ) by default, with a single Messaging Engine.

Faster disaster recovery in IBM Business Process Manager

Faster disaster recovery in IBM Business Process Manager

Implementing a multiple data center approach to improve recovery time

This article describes an infrastructure topology for IBM® Business Process Manager that includes elements that reside in distinct data centers that may be geographically separated from each other. Such a topology can be useful in achieving disaster recovery objectives in certain circumstances, especially when recovery times faster those offered by traditional approaches are desired. Additionally, the strategy described in this paper uses Oracle®'s Data Base File System (DBFS) to enable the database manager to control replication of the WebSphere® transaction and compensation logs, as well as traditional IBM BPM database content. This content is part of the IBM Business Process Management Journal.

Network File System (NFS) Recommendations for WebSphere Application Server to AVOID DATA LOSS


This article details some known issues with the Network File System (NFS) implementations that affect the reliability of data stored on such file systems by the WebSphere Application Server transaction, activity and compenstation services and the Service Integration Bus filestore. When reliability is compromised file corruption is possible. In most cases this results in DATA LOSS. It also makes recommendations for configuring both NFS and WebSphere Application Server based on known configuration problems and customer experiences.


Or, of course, you can store the tranlogs in a relational database table, subject to WAS 8.0.0.7 or upwards.

Using the global cache in WebSphere Message Broker

Using the global cache in WebSphere Message Broker

The new global cache feature in WebSphere Message Broker V8.0.0.1 enables you to store and reference data in an embedded memory cache or an external WebSphere eXtreme Scale grid. This article shows you how to implement a global cache to store and access reference data for use by message flows.

Introduction

Most enterprise IT solutions have a requirement for reference data that is accessed frequently during operations. Until recently, this reference data resided in either a file or a database and was accessed through queries. However, querying a file or database consumes time and must be done repeatedly, resulting in a substantial performance hit. To overcome this problem, applications started keeping reference data in a cache in memory, which greatly reduces the time needed to access the data.

IBM® WebSphere® Message Broker V8.0.0.1 (hereafter called Message Broker) provides various ways to manage the cache. You can use shared variables in ESQL to store the data in memory. But shared variables are private to a message flow and cannot be shared across message flows or execution groups, which can lead to duplication of stored data across different flows, and higher memory requirements to store the data.

Alternately, you can load static data into an execution group's JVM heap, so that the data can be shared by multiple flows deployed in an execution group. With this method however, the use of the data is confined to that execution group.

The new global cache feature in Message Broker enables a message broker application to store its reference data in an embedded or external WebSphere eXtreme Scale grid. In an embedded global cache, access to reference data is spread across multiple execution groups that host the eXtreme Scale container servers. The data can be accessed by all execution groups, even if they do not participate in hosting the container servers. This article shows you how to maintain and access static data in a global cache using Java routines from ESQL or Message Broker Mapping nodes.

A spot of IBM Tivoli Monitoring ...

This is an ongoing Work-in-Progress

The context is that we're looking at solutions to monitor a number of components, including base OS installations, IBM WebSphere Application Server, plus ancillary software, including IBM HTTP Server and the IBM WebSphere Plugin.

We're looking at feeding monitoring events back to Tivoli Monitoring, specifically Tivoli Enterprise Monitoring Server (TEMS), including OS-level activities ( Tivoli Monitoring Agent for Linux ) and log files ( Tivoli Log File Agent ).

IBM Tivoli Monitoring Wiki

Welcome to the IBM Tivoli Monitoring (ITM) WIKI. IBM Tivoli Monitoring products and solutions can help you manage the performance and availability of a wide range of distributed operating systems and applications.  This WIKI will provide you with valuable information and guidance on currently available IBM Tivoli Monitoring products and solutions.


The articles here provide valuable information related to monitoring agents.

Components of the monitoring agent

After you install and set up the Monitoring Agent for Linux OS (product code: klz or lz), you have an environment with a client, server, and monitoring agent implementation for IBM Tivoli Monitoring.

This IBM Tivoli Monitoring environment contains the following components:

• Tivoli Enterprise Portal client with a Java-based user interface for viewing and monitoring your enterprise.
• Tivoli Enterprise Portal Server that is placed between the client and the Tivoli Enterprise Monitoring Server and enables retrieval, manipulation, and analysis of data from the monitoring agents.
• Tivoli Enterprise Monitoring Server, which acts as a collection and control point for alerts received from the monitoring agents, and collects their performance and availability data.
• Monitoring Agent for Linux OS, which collects and distributes data to a Tivoli Enterprise Monitoring Server. This component also embeds the Agent Management Services function.
• Operating system agents and application agents installed on the systems or subsystems you want to monitor. These agents collect and distribute data to the Tivoli Enterprise Monitoring Server.
• Tivoli Data Warehouse for storing historical data collected from agents in your environment. The data warehouse is located on a DB2®, Oracle, or Microsoft SQL database. To collect information to store in this database, you must install the Warehouse Proxy agent. To perform aggregation and pruning functions on the data, install the Warehouse Summarization and Pruning agent.
• Tivoli Enterprise Console event synchronization component for synchronizing the status of situation events that are forwarded to the event server. When the status of an event is updated because of IBM® Tivoli Enterprise Console® rules or operator actions, the update is sent to the monitoring server, and the updated status is reflected in both the Situation Event Console and the Tivoli Enterprise Console event viewer. For more information, see IBM Tivoli Monitoring Installation and Setup Guide.


The Log File Agent is based on ITM autonomous agent technology (Autonomous agents don't require a full ITM installation) and is designed to monitor log entries on Windows, UNIX and Linux platforms from the following sources:

• Text log files
• Windows Event Logs
• UNIX/Linux Syslog

The Tivoli Log File Agent (product code LO) provides you with the capability to monitor Application log
files.

IBM Tivoli Monitoring is the base software for the Log File agent.

The Tivoli Log File Agent is an agent that provides a configurable log file monitoring capability that uses
regular expressions. For compatibility, the agent can consume the configuration information and format
strings previously used by the Tivoli Event Console Log File Adapter. These strings allow the agent to
filter the log data according to patterns in the format file, and submit only the interesting data to an
event consumer. The agent can send data both to a Tivoli Enterprise Monitoring Server or through the
Event Integration Facility (EIF) to any EIF receiver, such as the OMNIbus EIF probe.

Mac OS X - Applications and File Types - Changing the system-wide default

I inadvertently changed the default application for file type .RFT ( Revisable Form Text ) from TextEdit to OpenOffice.

This was, of course, an error.

Whilst I knew how to change the default for each individual file, I couldn't work out how to change the default for all files back to TextEdit.

This blog post came to my rescue: -

IBM Elastic Caching Community

Thanks to my IBM colleague, Jonathan Marshall: -


The future of the web is scale.  And when we're talking solving big problems, we mean, eXtreme Scale.  Large Volumes, Highly Available, Reliable, Transparent, High Performance, Scalable, Accessible, Secure, Usable, and Inexpensive are just a few of the benefits of using elastic caching.  
Data in memory is much quicker and easier to access than memory on disk. End user response times and system throughput are improved. Load on backend EIS and databases are reduced by large memory caches, thus increasing the workload you may process and your scalability. 

WebSphere eXtreme Scale provides huge memory stores on commodity hardware solving all these problems being a dynamic, elastic cache. What can't you do with large, cheap memory stores?
