Aide Memoire - Commands for Linux, WebSphere Application Server and IBM HTTP Server
   

I could print this stuff out, but then I'd have to carry paper - perhaps I should create an ePub with this stuff in ......

All of these came from this rather excellent blog: -


or, more specifically, this post.

Find the process that uses most CPU

ps -eo pcpu,pid,user,args | sort -k 1 -r | head -2

Find the last 10 process that use the most CPU

ps -eo pcpu,pid,user,args | sort -k 1 -r | head -10

Find cpu usage

mpstat -P ALL

Display the size of the current directory, plus all subdirectories

du -ch | grep total

Domain Information Groper (DIG) - look at DNS etc.

dig <hostname or IP address>

Get details of a network adapter

 /usr/sbin/ethtool eth0

Find occurrences of strings in files AND report file names

find . -name '*.xml' -print | xargs grep 'hostName' /dev/null

Find files over a certain size e.g. 10K

find / -xdev -size +1024 -exec ls -al {} ; | sort -r -k 5

Find and tar files on the fly

find /opt/IBM/WebSphere/PortalServer/log -name 'System*.log'| xargs tar -rvf System_logs.tar

Output wsadmin to console AND file

/opt/IBM/WebSphere/wp_profile/bin/wsadmin.sh -lang jython | tee wsadmin.log

Find files touched in, say, the past 20 minutes

find * -mmin -20

Run a command on a loop

watch -d=10 -n 1 "netstat -a"

Show expiry of WAS SSL key and trust stores ( assuming that password is still WebAS )

find /opt/IBM/WebSphere/wp_profile -name *.jks | xargs -i bash -c '/opt/IBM/WebSphere/AppServer/java/bin/java -classpath /opt/IBM/WebSphere/AppServer/java/jre/lib/ext/ibmjceprovider.jar:/opt/IBM/WebSphere/AppServer/java/jre/lib/ext/ibmjcefw.jar:/opt/IBM/WebSphere/AppServer/java/jre/lib/ext/US_export_policy.jar:/opt/IBM/WebSphere/AppServer//java/jre/lib/ext/local_policy.jar:/opt/IBM/WebSphere/AppServer/java/jre/lib/ext/ibmpkcs.jar:/opt/IBM/WebSphere/AppServer/java/jre/lib/ext com.ibm.gsk.ikeyman.ikeycmd -cert -list all -expiry -db {} -type jks -pw WebAS'

Show expiry of IHS SSL key and trust stores ( assuming that password is still WebAS )

find /opt/IBM/HTTPServer -name *.kdb | xargs -i bash -c '/opt/IBM/HTTPServer/Plugins/java/jre/bin/java -classpath /opt/IBM/HTTPServer/Plugins/java/jre/lib/ext/ibmjceprovider.jar:/opt/IBM/HTTPServer/java/jre/lib/ext/ibmjcefw.jar:/opt/IBM/HTTPServer/Plugins/java/jre/lib/ext/US_export_policy.jar:/opt/IBM/HTTPServer/Plugins//java/jre/lib/ext/local_policy.jar:/opt/IBM/HTTPServer/Plugins/java/jre/lib/ext/ibmpkcs.jar:/opt/IBM/HTTPServer/Plugins/java/jre/lib/ext com.ibm.gsk.ikeyman.ikeycmd -cert -list all -expiry -db {} -type cms -pw WebAS '

Oracle DB - Broken, now Fixed
Fri, Apr 18th 2014 1:25p   Dave Hay
So I managed to break my Oracle 11g database, and have now fixed it. The symptom was that, although Oracle was started, it wasn't really started. I kept getting "Connected to an idle instance" and "ORA-01034: ORACLE not available" as per the following: - sqlplus / as sysdba SQL*Plus: Release 11.2.0.1.0 Production on Fri Apr 18 19:53:56 2014 Copyright (c) 1982, 2009, Oracle.

IBM Redbooks: using Open Source with Liberty profile
Wed, Apr 9th 2014 11:45a   Dave Hay
The IBM Redbooks publication, Configuring and Deploying Open Source with WebSphere Application Server Liberty Profile was published last month and recently updated.

IBM Business Monitor - Unable to delete BusinessSpaces
Tue, Apr 8th 2014 8:25a   Dave Hay
One of my clients hit an interesting issue with IBM Business Monitor 8.0.1.1, that'd likely affect any product using BusinessSpace, including Business Process Manager. This was a newly minted environment, and we were quite able to create Business Spaces, but we were unable to delete them. There were no obvious exceptions in the WAS logs or in the underlying Oracle database. It was a bit of a puzzler. At my suggestion, the client raised a PMR with IBM Support, which came up trumps. The client me [read] Keywords: access control list acl ibm database oracle tivoli

WebSphere Portal 8 - Unified Task List Portlet with BPM 8.5
Fri, Apr 4th 2014 8:46a   Dave Hay
It's been a while since I posted anything about WebSphere Portal. When I started this blog, seven years ago, I was working in the Technical Sales team, within the IBM Collaboration Solutions (ICS) Brand of IBM's Software Group ( fka Lotus ), and WebSphere Portal was one of the software products upon which I specialised, along with IBM Connections ( fka Lotus Connections ) and IBM Web Content Manager ( fka IBM Lotus Web Content Management ).
