High processor usage on Websphere

MJLee ‎ 1,299 Views

If you run into a situation where the processor utilization is high - the process for determining the cause isn't the easiest thing to find on your typical Google search. So here it is:

For the sake of brevity I'm just going to do Linux

1) Take a javacore. This is easy on a Unix-type system. Just find your process and run "kill -3 <PID>"

2) Collect some top data

# top -bH -d 5 > top.out

3) Find the threads that are using the most processor usage in the top output

12771 user 20 0 6028m 2.3g 59m R 19.6 7.4 48:33.59 java
11880 huser 20 0 6028m 2.3g 59m R 19.6 7.4 46:41.38 java

4) Open up calculate and convert the PID to a hexadecimal value

For example 12771 -> 31E3

5) Open up the javacore and find your thread via the native thread ID.

3XMTHREADINFO      "WebContainer : 46" J9VMThread:0x00000000C4506C00, j9thread_t:0x00007FA9F66D2E10, java/lang/Thread:0x00000000091B2350, state:CW, prio=5
3XMTHREADINFO1            (native thread ID:0x31E3, native priority:0x5, native policy:UNKNOWN)
3XMTHREADINFO2            (native stack address range from:0x00007FA99EFE0000, to:0x00007FA99F021000, size:0x41000)
3XMTHREADINFO3           Java callstack:
4XESTACKTRACE                at java/awt/image/DataBufferInt.<init>(DataBufferInt.java:52(Compiled Code))
4XESTACKTRACE                at java/awt/image/Raster.createPackedRaster(Raster.java:469(Compiled Code))
4XESTACKTRACE                at java/awt/image/DirectColorModel.createCompatibleWritableRaster(DirectColorModel.java:1026(Compiled Code))
4XESTACKTRACE                at java/awt/image/BufferedImage.<init>(BufferedImage.java:323(Compiled Code))

You want to do this on different datasets so that you can confirm the pattern behavior is the same. So essentially just repeat the process

And that's it. Now that you have found the culprit, all you have to do is determine why that thread path is using up too much cpu.

Apple iPhone users: Are your texts being ignored by Android users?

CaseyToole ‎ 1,166 Views

Apple iPhone owners please read.

Do you have friends who previously had iPhones and switched to Android, who now ignore all of your texts?

Well maybe you aren't being ignored. Apple has a setting that will not send messages to Android numbers if the connections were previously established via iMessage.

To fix this:

Go to > Settings > Messages > and turn on the feature "Send as SMS" (Send as SMS when iMessage is unavailable.).

If this is working properly, your SMS texts to Android users should appear green. iMessage messages are blue.

The difference between following and being in network

MJLee Tags: connections ‎ 8,360 Views

in regards to notifications, the functionality of being in network and following has changed dramatically between Connections 3 and Connections 4. in Connections 3, if someone was in your network, you would be notified of things that person was doing in other applications. So you didn't need to follow that person or that person's blog in order to be notified of activity that the person generated.

But in Connections 4, the only way to get notified of a person's activity in another application (like Files, Forums, Activities, etc) is to follow them or the specific resource in the application. This may throw a lot of people off since it's not highly documented.

In the end, the functionality will be fixed and eventually the users will become accustomed to the new style of notifications. In the meantime, here is some info on what each of the states will do for you.

My network notifications in C4 were greatly reduced to ease the congestion in the activity stream.   It will focus on
    Status updates,
    Microblogging.
    Related comments,
    Reposting,
    Liking
    and possibly other information that could be associated with network activity.

My Notifications

Directed notifications from other users
Responses to end-user content across Connections
Any events explicitly targeted to the end-user by an IBM service

I'm Following

Despite its label in the UI ("I'm Following"), it displays more than only events about content the end-user is following. Events are surfaced as follows:

Any event surfaced under “My Notifications” (target events, such as responses to the end-users content)
Any event surfaced under “Action Required”
Any event from content being followed. Specifically in other applications

Checking out what's going on in the SystemOut.logs

MJLee Tags: websphere connections ‎ 2,699 Views

If you're in a Unix environment and hate having to check SystemOut.logs in multiple locations- Did you know you can get around that with a little scripting and taking advantage of ssh. The way it works it you use a private key to allow your script to authenticate and run a script on the node. This way you can just run a script to tail or grep for what you want to see and hit all the servers from a single machine.

I had to write this as part of a monitoring subsystem for another customer. Though this would be handy for almost anything repetitive in a multinode environment. So here is the snippet.

userHost=( user@host05 user2@host01 )

exitCode=0

# Location of the News SysOut logs.
newsSysOutDir=/local/opt/IBM/WebSphere/AppServer/profiles/AppSrv01/logs/clusterLC_server1

# Name of the monitor script
mon_script=SO_Mon.sh

# Test SSH access
for var in "${userHost[@]}"
do
echo "Directory listing for $var"
ssh -oBatchMode=yes -n $var "ls -l $newsSysOutDir"

    if [ $? != 0 ]; then
    exitCode= $?
    echo "SSH access is not configured"
       ssh-keygen -t rsa
    cat ~/.ssh/id_rsa.pub | ssh $var "chmod g-w ~/; mkdir -p .ssh; chmod 700 .ssh; cat - >> .ssh/authorized_keys2"

    echo "Configured SSH private key for $var. You will need to try again"
    fi

done
if [ $exitCode != 0 ]; then
    exit $exitCode
fi

# Upload the monitor scripts
if [ -z $isScheduledRun];then

echo "Uploading the monitor script"

for var in "${userHost[@]}"
do
scp $runDir/$mon_script $var:$newsSysOutDir/$mon_script
if [ $? != 0 ]; then
   echo "Upload of monitor script failed"
   exit 1
fi

done
fi

# Run the SystemOut.log monitor
for var in "${userHost[@]}"
do
# This is configured to work with sendEmail
ssh -oBatchMode=yes -n $var "$newsSysOutDir/$mon_script sendEmail wtfmail02.lotus.com michael_lee@us.ibm.com $newsSysOutDir "
done
echo "Kicked off the monitors"

# You can obviously run something here now to clean up the script .

Lotus Mobile Connect is Traveler Aware - use it for automatic assignment of users to HA Pools

CaseyToole Tags: enterprise-mobility mobility traveler lmc traveler-ha ‎ 1 Comment ‎ 4,568 Views

Today's post is about Lotus Mobile Connect and how it can be used with Traveler to make sure that mobile clients can reach the right Traveler HA Pool or Traveler server, in a secure manner with a clientless VPN connection.

First of all, many of you don't even know what LMC is. What is Lotus Mobile Connect? In a nutshell...

VPN solution supports all access points

● Laptop and Desktop (client)

● Handheld mobile device (client)

● Browser (clientless HTTP Access)

• Proven ROI - least cost routing & data optimization

● Network optimizations reduces network data costs

• Secure end-to-end connect to corporate intranets

● Strong authentication and support for RSA Secure ID

● End-to-end encryption: DES, Triple DES, RC5, AES and FIPS 140-2 certified

Clientless: No client software installation, application and platform agnostic!

Single Sign On: LMC Gateway + application authentication

Enhanced Security

– Same strong authentication and encryption algorithms as the LMC Mobility Client

– FIPS 140-2 certified platform. Contains latest secure SSL/TLS ciphers and industry standard authentication mechanisms

– Two way certificate validation available for additional layer of trust

– Configurable to run simultaneously with full VPN sessions. Multifunction, IT configurable remote-access solution (Example: Subset of users restricted to specific apps via clientless access only. Other set of users allowed expanded enterprise access with LMC Mobility Client.)

So what does it mean to be "Traveler aware"?

LMC 6.1.4 Traveler Aware Features

Recognition of Traveler URLs,
applies data flow optimizers and HTTP header tags,
previous password recognition (prevent LMC server lockout).

LMC 6.1.5 (NOW IN BETA!!) Traveler Aware Features

With the current set up of Traveler, a user has to know their URL to their Traveler server or Traveler HA (High Availability) Pool. When customers are deploying to large numbers of people, it can be a pain to have so many profiles out there pointing to different Traveler servers or pools. In the deployment that I just did, they are planning on 4 pools (I completed 2), each pool supports about 10,000 users. However, this customer did not want to have 4 different possible Traveler profiles on their Apple iOS Mobile Devices.

Enter the new LMC 6.1.5 Traveler aware feature...

The new LMC 6.1.5 Traveler aware feature allows LMC to go into a single URL mode. LMC "learns" which server or pool of servers a user belongs to, and makes sure that the user is routed properly. So in a High Availablility scenario, you still need a load balancer in front of the pool, but if you have more than one Pool, LMC will route the users to the right pool. It knows how many users belong to each server or pool of servers, and will divvy up new users to a less loaded pool. Pretty cool, huh? Look for LMC 6.1.5 some time in Q3!

Transaction timeouts are your friend

MJLee Tags: connections ‎ 2,023 Views

It's odd how some things come in waves. Recently I have been seeing a lot of issues at once where the database server that Lotus Connections uses can get itself stuck on a call. The next thing you know, the whole system is fried and people are calling in to complain. You can avoid a lot of pain by proactively tuning your system.

First off, the JDBC connection timeouts in WAS are set to 180 seconds. This is a little conservative but ultimately what's right for your users may differ between environments. Some user populations may be good with 15 seconds. Others may prefer to have 60+ seconds.

Secondly, you will want to trim the time the database will get stuck on a transaction. For most applications, it's set to unlimited. That's a problem waiting to happen. Each DB handles their systems differently.

For Oracle, you need to implement a user profile and apply it to the user. I would recommend dropping the CPU_PER_CALL value to something less than the JDBC connection timeout. This will let the application know that it's a database issue as the timeout will general a reason code.Though, since it's measured in CPU time and not real time, it can be pretty tricky to do that.

http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10759/statements_6010.htm

For DB2, you need to implement the LOCKTIMEOUT value. It's part of each database's configuration. Again, you want to make sure that the timeout is less than the JDBC connection timeout. This is a bit easier to configure since it's measured in real seconds.

http://pic.dhe.ibm.com/infocenter/wasinfo/v6r0/index.jsp?topic=%2Fcom.ibm.websphere.express.doc%2Finfo%2Fexp%2Fae%2Frprf_db2parameters.html

I know an environment that has had Connections for awhile and have a couple hundred thousand users. They found they lowering the locktimeouts to 45 seconds helped a lot.

A Lotus Connections general troubleshooting steps

MJLee ‎ 2,188 Views

IBM does a great job of putting together the documentation you need to support Lotus Connections problems. Though finding it all when you need it can sometimes be a challenge. Below is a list of the documents you can use to take that first step in diagnosing your issues and even using debug to take it one step further.

Test the reproducibility and try variations

Different browsers
Different users
Different services

Different locations

Follow the general troubleshooting in the docs below. If that fails, implement the trace strings for each service and open a PMR:

Setting up the Connections accounts in Lotus Notes to use SPNEGO

MJLee Tags: notes connections lotus spnego ‎ 11,150 Views

Having a SPNEGO configuration with your Connections account in Lotus Notes can make using and administering Connections widgets so much easier. But right now, setting it up to use is not a simple proposition. Unfortunately I learned the hard way that there are some issues that make using this configuration difficult/impossbible to implement until some of these issues are fixed in the future code. That is unless you know some tricks to get around those problems.

Let's start out by going over how you would think to implement the configuration in Lotus Notes. If you are going to set up SPNEGO in your Connections account for an individual user you might go to your preferences and click on the Connections entry the list. Then you would check the "Enable IBM Connections Features" checkbox. Next you would enter the URL into the "Server URL" field. Then click on the "Advanced" button and choose the "OS Credential" option. That sounds like it should be pretty simple and someday that may be all you need to do. But for now let's go over some of the things that you will need to do to get this working.

The first thing to take care of is the krb5.ini. This is the Kerberos configuration file that Lotus Notes is going to need to initialize SPNEGO in your Windows environment. It will need to be placed in the < Lotus Notes>/framework/rcp/deploy/extras directory. Below is an example of how this file needs to be configured.

[libdefaults]
default_realm = <change to something like IBM.COM/Should be the AD Domain>
default_tkt_enctypes = des-cbc-md5 rc4-hmac
default_tgs_enctypes = des-cbc-md5 rc4-hmac
[realms]
SERVER.IBM.COM = {                                                   (This line should not be changed)
kdc = logonserver.ibm.com:88                                (change to the value of your logonserver.   You can get this by typing echo %logonserver%)
admin_server= logonserver.ibm.com:88                  (change to the value of your logonserver.   You can get this by typing echo %logonserver%)
default_domain = <change to something like ibm.com>
}
[domain_realm]
.ibm.com = <change to the realm value to be used. ie. IBM.COM>
ibm.com = <change to the realm value to be used. ie. IBM.COM>

A couple gotchyas that are relatively minor are that when you set up your Connections preferences you need to specify "https://" address as the server the server URL. And you will want to use the "https://<hostname>/activities/service/authredirect.jsp" for the Authentication URL field. (NOTE: Greenhouse doesn't support SPNEGO. I'm just using this as an example)

After making these changes you may still find that SPNEGO doesn't work as you would expect. Well one reason may be that you are an administrator on a Windows 7 PC. This is a quirk of the UAC in Windows. In order to get SPNEGO to work you can right-click the Notes icon when you start and choose "Run as Administrator".

This should work to get your Activities widget working. But many times you'll want to do something like use another widget. For example the "Status Updates" widget is very popular. But if you're using SPNEGO you'll notice that the thumbnail pictures of users may not be coming down. this is a known issue that you can address by adding a line to your plugin_customization.ini file. This is located in your <Lotus Notes>/framework/rcp/ directory. This changes the behavior of the plug-in to pull the images via a feed mechanism.

com.ibm.lconn.statusupdates/download.image.enabled = true

PUSHING IT OUT

So after making all those changes you should now have a working SPNEGO enabled Connections account on your Lotus Notes client. What you usually end up wanting to do from this point forward is to push these changes out to a large group of users. The way to do that is through Policies. If you go to your Name and Address book go to your Policies folder and click on the Accounts view. Click on the Add Account button and start filling out the form. The key fields will be the "Account type" which should be Connections; the "Connections service URL"; and the "Authentication URL" on the Advanced tab. Also on the Advanced tab, you need to choose the Authentication type and set that as OS-CRED.

The most important trick to pushing this policy out is to place the krb5.ini in the Account file field. This will place that file in the rcp/deploy/extras folder. Note: You can only place one file in this field. So this will be problematic if you need to create a custom icon.

For the issues associated with the UAC causing authentication failures when using SPNEGO, there are a couple options. One you can create a VBS script that will starts the notes program with elevated privileges. Or you can modify the shortcut. Right-click on the icon and select properties. You will see a Compatibility tab and on that you can choose to check the "Run this program as an administrator" option. Both of these options have the negative side effect of creating a pop-up that alerts you to the fact the program will need to run with elevated privileges. If you want to bypass that's pop-up, you can create a scheduled task that will run with elevated privileges and then start that task via a shortcut.

Note: You need to be an administrator for these. Regular users will not need to implement these options to get SPNEGO to work.

Dim oShell,oExec
If WScript.Arguments.Named.Exists("elevated") = False Then
   CreateObject("Shell.Application").ShellExecute "wscript.exe", """" & WScript.ScriptFullName & """ /elevated", "", "runas", 1
   WScript.Quit
Else
   Set oShell = CreateObject("WScript.Shell")
    oShell.CurrentDirectory = CreateObject("Scripting.FileSystemObject").GetParentFolderName(WScript.ScriptFullName)
End If
Set oExec = oShell.Exec("notes.exe")

Start tasksch.msc
In the Left hand pane, go to the Task Scheduler Library
In the Right hand pane, click Create Task

General Tab: 1) Give the task a name; 2) check Run with highest privileges; 3) Configure for Windows 7
Actions Tab: 1) New - Start a program, 2) Start in <Notes data directory>

Conditions Tab: 1) Uncheck "Stop if the computer to battery power"; 2) Uncheck "Start the task only if the computer is on AC power

Settings Tab: Uncheck "Stop the task if it runs longer than"

The task you created will now show up in the middle pane.

Create a shortcut
Right click on the desktop and choose New -> Shortcut
For the location -> schtasks /run /tn <taskname>

click Next
Type what you want to call the shortcut and Finish

Social everywhere

MJLee Tags: connections ‎ 1 Comment ‎ 3,494 Views

It's surprising to me that people are not aware of how important social media is to business communication. I mentioned how important social business was to the Lotus brand to a bunch of email guys. Their jaws just dropped.

I recently heard a podcast where Connections was called the flagship product for Lotus. I'm not sure what my take on that statement is but it is definitely a strong indicator of sentiment.

The SWAT team is dedicated to embracing this. They have been taking on the challenge of doing their business in a social fashion which in itself is a huge undertaking. The question is invariably the same as it was 4 years ago. How do you communicate with people that aren't used to communicating that way previously?

Social media is a new paradigm now in the way that email used to be a new paradigm. Back in the early 90's when email was starting to really take hold, it was a requirement to directly communicate with people. The key word there being "direct". Using tools like Connections is a great way to indirectly communicate with a greater audience. The goal is to reach people that weren't or are not immediately available. Social is about leveraging those next tier relationships where you get value that you didn't know was there. I think what you are going to start to see is more and more social integration until we reach a tipping point and the paradigm shifts.

Right now, there are a bunch of different players in this space and I believe it's still evolving. A fairly recent Gartner report shows Connections in a close race with Jive and Microsoft. But having seen the others, I have to think that Connections has hands down more to offer. IBM has the most impressive stack of social business applications and integration. When you are talking depth and breadth of a product, I'm still trying to wrap my head around how Connections isn't blowing everyone away. Perhaps that's just because I'm an IBM'er.

Cool tooling for moving users

MJLee Tags: adminp domino ‎ 1 Comment ‎ 3,847 Views

Our team gets called in to doing a wide range of tasks to help get through some pretty painful situations. As part of that, we have a pretty healthy production of tools to make it possible to do somethings that aren't currently available. Rob Mathews created an AdminP application that makes mass moving users much much simpler. Rather than trying to track down status and management features in different places, he put it all into one place. This is especially helpful if you have to move a great deal of users.

A lot of these tools are not available through normal channels. But if this is something that you think you might need, let me or your local SWAT team member know.

Remember your IO

MJLee Tags: domino performance sametime ‎ 3,045 Views

I was talking some recent SWAT activity with our local Sametime Guru - Casey Toole. We had a couple really painful issues that came up recently. Issues like a server going down, long service outages and tons of scrambling to get things back in order. Well once the dust settled, these problems all came back to being able to conduct high quality reads and writes to the filesystem.

What makes this an especially painful process is that in most shops, the application administrator (Domino, Sametime, Connections etc.) doesn't have the power to address disk subsystem issues. And the last thing you want to do is be stuck in a situation where people are screaming about service and you are having to prove the problem is with someone else. Let's say responsibility is never readily accepted 9 times out of 10,

So before you do anything, make sure that your disk subsystem is healthy . Check your response times and your error logs regularly. And don't forget a daily dose maintenance.

Multi-Database search

MJLee Tags: lotus domino notes ‎ 7,579 Views

One of the coolest things you can do with the Notes client is plug in functionality that someone else has written. If you are like me then your mail archive has way more documents than your mail database. And going from database to database is a pain.

To help fix this, Bob Balfe wrote a plugin that can search multiple databases for you. All you need to do is drag and drop the widget from the following page:

http://blog.balfes.net/2010/10/25/new-openntf-project-multiple-database-search/

After that it's just about clicking the databases you want to search and then running a search from the toolbar. The most amazing thing about all this is how few people know that it is available to them.

Our team

MJLee Tags: support swat lotus ‎ 2,671 Views

Our team started out as an area of support somewhere between L2 and development. We are particularly suited to issues that dealt with more complexity or required a more in depth approach to resolution. Though most customers don't even know who we are. I did a couple user group presentations and found out that SWAT sightings may seem like seeing a yeti. But that can be a good thing. It can mean that our front end teams and processes are doing well enough they don't need us.

But seeing things through our eyes might be handy. Our team generally gets involved when the stakes have been raised for one reason or another. So we get to see some interesting things. And sometimes shocking things.

We have people that cover Lotus Notes/Domino, Sametime, Quickr, Connections and Portal. Hopefully, this will be a good place to learn some interesting things about the products, support and what you can/should be doing in your environment.

Stay tuned.

Re: Automatic Application of Portal Tuning Parameters

In response to: Automatic Application of Portal Tuning Parameters

Many Customer are asking what is changed by using this tool. I have performed some research on the tool and based on the Tool update from 03/19/14 here is what I have found related to the configuration changes that are performed by the tool

The Bulk of the tuning changes that will be performed for the JVM and web container service are found in the TuningTask directory in the archive in the file named tuning.properties. The first 5 lines are what the user sets for the environment they are configuring as follows
# - this is set to true if wcm rendering is being used on the site
tuning.wcm=true
# - set the following to true for a subscriber only :ie this does not syndicate content to other environments
tuning.wcm.subscriberOnly=true environments
#- this is set to false of running the command against a rendering environment and true if it is an authoring environment
tuning.wcm.authoring=false - only set this to true for authoring environments

# managed pages is a Portal V8+ feature that allows WCM to manage page #definitions. If you want the "edit" button on the V8 theme, you have to set #managedPages to "true"
tuning.wcm.managedPages.inlineEdit=true
#set the bit level of the jvm environment being configured
tuning.os.bit=64

#The other properties in this file sets the JVM Heap initial amd Max size as well as
# other generic jvm arguments depending on the OS being used per the tuning
# guide recommendations the values here are the values that will be configured in
# the Process definition for the Server being configured

# The properties from here to the end of file are recommendations from IBM on the
