#1 Use custom user for WebSphere services
• Stopping WebSphere requires a user and password
– soap.client.props
– Service definition (/etc/init.d/ or Windows registry)
• Increase security
– Use different passwords
• Plain password on Linux
• Encoded (not encrypted) on Windows
– Create a local WebSphere user with “operator” access level
• WebSphere service user only needs access level to start/stop/restart the
environment
7

#2 globalSenderEmailAddress is not working
completely
• <property
name="globalSenderEmailAddress">mail@mail.com</property>
<property name="alwaysUseGlobalSender">true</property>
<property name="globalSenderName">Connections
Newsletter</property>
• If you use globalSenderEmailAddress (notification-config.xml)
– Mails contain reply-to address “news-admin@example.com”
– So replies of users can’t be delivered
• You need to configure all mail addresses one by one
8

#3 Do not change the Community catalog
seedlist url
• Using https://cnx.pana.local
– Connections will try to access seedlists using HTTPS on host cnx.pana.local
– Does not support TLS 1.2
• Using https://localhost
– This is the default value which will do something complete different
– Connections will use a internal (not HTTPS) request to access the seedlists
– Supports multi-node environments
9

#4 WAS & 4096-bit SSL keys
• Will not work out of the box if using 4096-bit key
• On IBM HTTP Server
• With any third-party integration (iNotes, …)
• You need to copy the unrestricted java policy to every node
– Download here
https://www14.software.ibm.com/webapp/iwm/web/preLogin.do?source
=jcesdk
– Copy to <was_home>/java/jre/lib/security
– You need to redo this every WebSphere Java update ;-)
• WAS is now able to connect to those hosts
10

#5 Configure Textbox.io using JVM generic
properties
• You can use JVM generic properties instead of the
application.conf file
– -Dephox.allowed-origins.origins.0=https://cnx.pana.local
-Dephox.allowed-origins.origins.1=http://cnx.pana.local
-Dephox.allowed-origins.url=https://cnx.pana.local/ephox-allowed-
origins/cors
– Skip the last line for 5.5 CR2 and later
11

#6 Do not trigger seedlist validation regularly
• Seedlist validation does NOT delete temp files
– New seedlist data will be created every time
– Could cause full disk space
• <localdata>/search/persistence/seedlist*.attempted.xml
• Amount depends on environment
• Happens when
– Accessing /search/serverStatus
– Calling SearchService.validateSeedlist("")
12

#7 Tuning your database
• Heavily increase performance by running DB2 maintenance
tasks
• Scripts available within <cnxroot>/xkit/connections.sql/
• Run in following order:
– Runstat
– Reorg
– Runstat
• Run them regularly
• You need to build own scripts for custom databases
– https://meisenzahl.org/2017/02/25/connections-database-performance-
tuning/
13

#8 You’re using SPNEGO and don’t know
LimitRequestFieldSize?
• If so, some of your users may be unable to use SSO
– Users with many group memberships
– Mostly VIPs ;-)
• SPNEGO authentication header can have up to 12392 bytes
– Default LimitRequestFieldSize size is 8192 bytes
• Add LimitRequestFieldSize 16384 into your httpd.conf
– Will prevent: HTTP 400 - Bad Request (Request header too long)
– The whole group membership is stored within the header
14

#9 “TLS 1.2 only” environments
• Possible, but you need:
– Connections 5.5 CR2 including latest Textbox.io, FEB
– WebSphere 8.5.5.9
• FileNet Config Manager will not work
• Docs/Viewer will need a httpd.conf customization
– RewriteCond %{HTTPS} !=on
RewriteCond %{Request_URI} !/docs
RewriteCond %{Request_URI} !/conversion
RewriteCond %{Request_URI} !/viewer
https://%{SERVER_NAME}/$1 [NE,R,L]
• You need to configure some more stuff
• Please do not try this with a previous Connections version!
– You will find the whole story here
https://meisenzahl.org/2016/10/26/using-tls-1-2-only-configuration-with-
ibm-connections/
15

#10 Tuning search index
• Only use one search dictionary!
– Issues since Connections 2.5
• Enable “Accent-insensitive search”
– You will find “René” when searching for ”Rene”
• Enable “1 to 2 matching”
– You will find “Stoettner” when searching for “Stöttner”
• Include Connections type ahead search (Apache Solr)
• “Ignore Punctuation” setting is not working
– Searching for “IBM” will not display “I.B.M” within results
16

#11 Do not use IBM JRE for Apache Solr
• Apache Solr is needed for Connections type ahead search
• IBM JRE will break some Solr Dashboard Widgets
• More information (thanks Ben!)
– https://collaborationben.com/2016/06/22/which-jre-to-use-with-ibm-
connections-solr/
17

#12 How-to: Set EMPLOYEE_EXTENED role for
all users
• Export all user mail addresses using a SQL export
• Change role using a wsadmin call
– ProfilesService.setBatchRole(EMPLOYEE_EXTENDED, "mail.txt")
• More information
– http://www.stoeps.de/adding-employee_extended-to-all-users/
• Changing role directly within the database is not supported!
18

#13 Using Textbox.io spellchecking service with Chrome
• You need to import your SSL chain into the WebSphere cacerts
store
– cacerts store is located in <was_home>/java/jre/lib/security
– You need to redo this every WebSphere Java update
• If not, you will get a HTTP 500 for https://<url>/ephox-
spelling/1/correction
• More information (thanks Michael!)
– https://www.urspringer.de/2016/02/16/ssl-certificate-issue-with-ephox-
textbox-io-editor-in-ibm-connections-5-5/
19

#14 Read-only and read-write profile fields
• Synced profile fields should be read-only!
• Please recheck your configuration
– We have seen this too many times!
• Customize profiles-type.xml as needed
– readwrite
– read
20

#15 Old URL preview thumbnails are missing after a
migration
• Thumbnail file path is stored within database
– Hard coded, no variables are used
• You need to manually adjust them after changing the
Connections shared directory path
• More Information
– https://meisenzahl.org/2016/06/28/url-preview-pictures-not-displayed-
migration/
21

#16 ACCE (FileNet Admin Interface) login isn’t
working
• Exclude /acce from mod_deflate (httpd.conf)
– SetEnvIf Request_URI ^/acce(.*) no-gzip dont-vary
• Use English as browser language
22

#17 Extend SPNEGO exclusion filter
• Prevent issues with some widgets
– request-url!=/profiles/widget-catalog/;request-
url!=/Calendar.xml;request-url!=/Recomm.xml
• When using Docs or/and Viewer
– request-url!=/docs/;request-url!=/conversion/;request-url!=/viewer
• When using Mac Connections Plugin
– request-url!=/files/serviceconfigs
• Tip: Save krb5.conf and keytab outsize the WebSphere java
folder
23

#18 FEB browser setup isn’t working
• Launches on new installation or upgrade when access /forms
• Will not work with non-English browser languages
– UI is only available in English
• Tip: Use portable Firefox
24

#19 Post-upgrade task: Connections fixes
• Delete temp directories after every iFix or CR update
– <appsrv-profile>/temp/*
– <appsrv-profile>/wstemp/*
• If not, you will get nice UI bugs ;-)
25

#20 Wiki images are missing after 5.5 GA
upgrade
• Short mod_rewrite rule will fix this issue
– RewriteRule "^/library/(.*)" "/wikis/form/api/library/$1" [R,L]
• Do not use the fix IBM provided
– Insecure mod_proxy configuration!
• Fixed with 5.5 CR1
– http://www.stoeps.de/missing-images-in-wikis-after-migration-to-ibm-
connections-5-5/
26

#21 Debug FileNet without ACCE
• Why? You have issues on startup or you are unable to access
/acce
• Add debug settings using JVM generic properties
– -DskipTLC=true -Dlog4j.configuration=file://log4j.xml
– https://meisenzahl.org/2015/12/13/debugging-filenet-issues-without-
using-acce/
27

#22 Enable HTTP compression on IHS
• LoadModule deflate_module modules/mod_deflate.so
• DeflateCompressionLevel 6
• AddOutputFilterByType DEFLATE application/atom+xml
AddOutputFilterByType DEFLATE application/atomcat+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/json
AddOutputFilterByType DEFLATE application/octet-stream

• SetEnvIf Request_URI ^/acce(.*) no-gzip dont-vary
SetEnvIfNoCase Request_URI .(zip|exe|jar|gz|jpe?g|png)$ no-gzip dont-vary
Header append Vary User-Agent env=!dont-vary
28

#23 When doing a FileNet or Docs upgrade…
• …do not forget to remap applications
– FileNet & Navigator
– Docs, Viewer & Conversion
• Without they will not be accessible through IHS
29

#24 Recheck /docs and /viewer interservice URL
• There were some issues in previous versions
– Missing interservice URLs
– Double entries
• Some stuff isn’t working properly without
– CCM integration
– Access file preview via Activity Stream
30

#25 How-to: Delete Communities using REST
• First REST call will put the Community into the trash
• Second call will purge the Community completely
• Tip: When creating Communities within monitoring checks you
should execute the REST call twice!
– https://www-
10.lotus.com/ldd/lcwiki.nsf/xpAPIViewer.xsp?lookupName=IBM+Connectio
ns+5.5+API+Documentation#action=openDocument&res_title=Deleting_
communities_programmatically_ic55&content=apicontent
31

#26 Post-upgrade task: Connections database scripts
(DB2)
• Recheck NUMDB value after every Connections database
upgrade
– db2 get dbm cfg | grep NUMDB
• SQL update scripts sometimes include NUMDB settings
• If not, you will get issues when using integrations like Docs, FEB
or third-party
32

#27 Oracle: Check user password expiration
• Oracle database users are created through the Connections
Wizard SQL scripts
• Oracle default user password expiration value is 365 days
– ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED
33

#28 Debug user synchronization
• Profile & user synchronization
(<tdisol>/etc/profiles_tdi.properties)
– source_ldap_debug=true
– debug_update_profile=true
– debug_collect=true
• TDI issues (<tdisol>/etc/log4j.properties)
– log4j.rootCategory=DEBUG, Default
• sync_updates_clean_temp_files=false
– This will force TDI not to delete the temp files
• LDAP export
• Database export
34

#29 Connections and Docs with UNC share
access
• Recheck your configuration after installing Connections or Docs
UNC share access
– WebSphere variables - Slashes have to be forward slashes
– sib-engine.xml - Slashes have to be backward slashes
• Alternatively use ${MESSAGE_STORE_PATH}
• More information (Thanks Victor!)
– https://notesbusters.com/2016/02/22/connections-5-5-install-problem-
for-websphere-cluster-settings-with-unc-shares/
35

#30 Don’t miss the DB2 license import
• DB2 will work 90 days without a license
• You can check your license status using db2licm –l
– Expiry date: "Permanent“
• Tip: You will need a new TSAMP license when using DB2 HADR
with TSAMP after upgrading to DB2 10.5 FP8
36

#31 Debug Windows Connections plugin
• Launch DITrace.exe (<installpath>/Connections Desktop
Plugins)
• Reproduce issues

• Notes 8.5.x and < TLS 1.2 support (SSL LABS A-)
– SSLCipherSpec ALL +TLS_RSA_WITH_AES_128_CBC_SHA38

#33 Enable Viewer to preview .xlsm
• Required versions
– Connections 5.5 CR2
– Docs 2 CR1
• You need to customize viewer-config.json and include some
MIME types
• Editing macro enabled files will work out of the box
– https://meisenzahl.org/2017/01/01/preview-xlsm-files-within-ibm-
connections/
39

#34 Reimport Highway settings after 5.5
migration
• Otherwise, Activity Streams (Homepage, Profiles) will not work
– Access issues caused by missing permissions
• Copy “00000000-0000-0000-0000-000000000000.json“
– From <cnxshared>/configuration/
– To <cnxshared>/configuration/update

tream_in_Profiles_after_migration?lang=en
40

#35 Connections 5.5 browser push notification
• New App: PushNotification
• Based on long-polling requests
– Client sends POST request to /push/form/comet/connect
– Server holds the request open and waits until response information
becomes available
– Server responses or timeout kills the request
– Client sends new POST request...
• Recheck your threads configuration on IHS and WAS
– ThreadLimit in httpd.conf
– Web Container Thread Pool for every App-Server
41

#36 Customize log language
• WAS: Customize JVM generic properties for all JVMs
– -Duser.language=en -Duser.region=US
– Non-English logs are causing issues
• TDI: Customize ibmdisrv.sh/bat
– LOG_4J="-Dlog4j.configuration=file:etc/log4j.properties” -
Duser.language=en -Duser.region=US
42

#37 Secure your mod_proxy configuration
• LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
• ProxyRequests Off
• <Proxy *>
Order deny,allow
Allow from all
</Proxy>
• ProxyPass /abc http://<fqdn>/abc
ProxyPassReverse /abc http://<fqdn>/abc
43

#38 Monitoring WAS
• Using PMI
– Analyze WebSphere related stuff (Connections pool size, Heap size)
– Included
– More information
• http://www.ibm.com/support/knowledgecenter/SS7K4U_8.5.5/com.ibm.webs
phere.nd.multiplatform.doc/ae/cprf_pmidata.html

– Eclipse IDE Plugin
– More information
• http://www.ibm.com/support/knowledgecenter/SS3KLZ/com.ibm.java.diagno
stics.healthcenter.doc/topics/introduction.html
44

#39 Configure log rotation
• WAS
– Within JVM settings
– Don't forget to configure all JVMs
– Issues within Connections installer
• Recheck settings after installation!
• DB2
– db2 update dbm cfg using diagsize 256
– Delete logs after X days (crontab, scheduled task)
• TDI
– Customize <tdisol>/etc/log4j.properties
• log4j.appender.Default=org.apache.log4j.RollingFileAppender
log4j.appender.Default.MaxFileSize=10MB
log4j.appender.Default.MaxBackupIndex=10
• IHS
– Customize httpd.conf
• ErrorLog "|/<ihsroot>/bin/rotatelog –l /opt/IBM/HTTPServer/log/error_log.%Y.%m.%d 10M"
• CustomLog"|/<ihsroot>/bin/rotatelog –l /opt/IBM/HTTPServer/log/access_log.%Y.%m.%d
10M" common
– Delete logs after X days (crontab, scheduled task)
45

#40 How-to: Add customized profile types
• Why?
– Customize displayed/available profile fields
– Enable or disable profile widgets
• Configure “profileType” within
map_dbrepos_from_source.properties
• Customize profiles-types.xml
• Customize widgets-config.xml
– <layout resourceSubType=”<customprofile>”>
…
</layout>
– profileType default needs to be the last one
46

#41 How-to: Configure mobile push using forward proxy
• Connections environment is unable to connect to Apple/Google
push gateway directly
• Customize mobile-config.xml
– <ProxyHost> </ProxyHost>
<ProxyPort> </ProxyPort>
• Configure authentication alias if needed
– proxyMobilePushNotificationJAASAuth
47

#42 WebSphere & DH key size
• WAS supports only 2048 bit or less
• Enforce a specific DH key size
– <washome>/java/jre/lib/security/java.security
• jdk.tls.disabledAlgorithms=DH keySize <768
• Define DH key size on Domino
– Default DH key size was increased to 4096 bit with Domino 9.0.1 FP4 IF2
– SSL_DH_KEYSIZE=2048 (notes.ini)
• Requires at least Domino 9.0.1 FP3 IF2
– Mail integration!
• More information (Thanks Ben!)
– https://collaborationben.com/2016/07/12/ibm-connections-mail-and-
ephemeral-diffie-hellman-key-size-error/
48

#43 Post-upgrade task: CR2 Surveys
• Rewrite /forms to prevent broken links/bookmarks
– RewriteRule ^/forms/(.*)$ https://%{SERVER_NAME}/surveys/$1
[NE,L,R]
49

#44 Extend wsadmin on Linux
• rlwrap will allow you to use command history and arrow keys
within wsadmin
– https://github.com/hanslub42/rlwrap
• rlwrap ./wsadmin –lang jython
• This is also working for other command line based tools
– db2
– SQLPLUS
50

#45 Include mobile links in notification mails
• Allows users to access content using Connections mobile apps
• notification-config.xml
– <includeMobileLinksInNotifications>true</includeMobileLinksInNotification
s>
51

#46 Monitoring IHS
• Customize httpd.conf
– LoadModule status_module modules/mod_status.so
– <IfModule mod_status.c>
ExtendedStatus On
<Location /server-status>
SetHandler server-status
Order deny, allow
Allow from 127.0.0.1
</Location>
</IfModule>
• Access using /server-status
52

#47 Enable LDAP groups with two or more Domino
directories
• Enable your Connections environment to use more than one
Domino directory
– Internal and external users
– Special directory topology
• Define your repositories with their Base DN
• You need to edit the wimconfig.xml
– These changes are not supported within ISC
• Customize following lines (one line for every repository)
– OLD: <config:baseEntries name="o=pana"
nameInRepository="o=pana"/>
NEW: <config:baseEntries name="o=pana" nameInRepository=""/>
– No need to customize other lines!
53

#48 connectionsAdmin J2C role
• Do not use a local WebSphere repository user
• Many problems are related to this
– Thumbnail generation in Gallery (3.0)
– CCM and Docs stop working after some time (5.5)
– Easier CCM migration (side-by-side)
• Changing the connectionsAdmin user is possible
– https://www-
10.lotus.com/ldd/lcwiki.nsf/dx/Change_password_of_connectionsAdmin
54

#49 Mail Integration with external users
• Mail Integration should be deactivated for all external users by
default
– header.jsp script is not working correctly
– ROLE_mail-user Cookie is set to true
• Use LDAP group instead of “All authenticated in Application's
Realm” to prevent errors
– mail-user role needs to be changed in following Apps
• Common
• WidgetContainer
55

#50: Use variables in widgets-config.xml
• Widget documentations often show path names in widgets-
config.xml
• Or even worse copies files to application ear
• Better move the files to
{CONNECTIONS_CUSTOMIZATION_PATH}/communities
• Use {communitiesSvcRef} as a replacement in widgets-
config.xml
• If you want to change the PATH, just change the WebSphere
variable
