Howto: Troubleshooting

Reproduce the error

• Reproducible and/or periodically?• A sequence error?• Client-side or server-side problem?• Analyze the root cause

Be aware of the big picture

• Client-side problems• DebugindifferentBrowsers(IE,FF,Chrome)• DoNOT useaserverIE

• Server-side: IBM Connections is based on many components• debugon“highlevel”first• getanoverviewwhichbackendserviceiscausingtheerror

Configuration changes

• Changes in…• Connectionsconfiguration• Backend(WebSphere,Database,HTTP)• Firewallornetwork• OS,hardwareorVMTip:Eventhesmallestconfigurationchangecanhavebigconsequences!

Analyze log files and browser

• Analyse log files• Atom.io,Notepad++or less/tail• Baretail or tail –f• ELKstack

• Tools for client-side problems• FirebugorDeveloper-Tools• BurpSuiteorFiddler

Analyze root cause

• Find a hint inside the log• NetworktimeoutorDNS• SQLerrors• LDAPerrors• Syntaxerrorsinconfigurationfiles„xxx-config.xml“

• ErrorstackTip: In a clustered environment, start and analyze only one Node (if possible)

Troubleshooting

Get the cow off the ice

How to do this?

Agenda

WebSphere Application Server (IBM Connections) logs• SystemOut.log• SystemErr.log• trace.log (if tracing is enabled)• Log path:

• <wasroot>/profiles/<profilename>/logs/<servername>/

Analyze WAS log files

• Time stap: 24h time stamp with milli-seconds • Thread id: eight character hexadecimal value• Short name: typically java class name• Event type: one character only (E, W, I,…)• Message identifier: String based on component• Message: Some information

WAS Event types

• F - Fatal message• E - Error message• W - Warning message• A - Audit message• I - Informational message• C - Configuration message• D - Detail message• O - Messages that are written directly to System.out

by an application• R - Messages that are written directly to System.err by

an application• Z - Place holder to indicate type was not recognized

WAS Message identifier

• Prefix by Application or Server (CLFRW)• Specific application code (0042)• Event Type (I)

Read trace stack

• First line displays key information• “Caused by” displays root cause

Environment information

• First log lines on server startup• WebSphereversion• OSversion,Processid• Installationpath

Enable tracing

• Enable tracing using ISC• Runtimeorconfigurationonly

• Define tracing based on• Appprefix/errorstack• Mustgather(PMR)

Search issues

• http(s)://<fqdn>/search/serverStatus• Displayindex,seedlists,loginformation• Dataisdisplayedforone nodeonly

• Usingnodefqdn toaccessdifferentnodes

Debug Search

• Search queries (runtime)• com.ibm.connections.search.index.searching.*=all

• Crawling & seedlists• com.ibm.connections.search.index.indexing.*=all:com.ibm.connections.search.seedlist.*=all:com.ibm.connections.httpClient.*=all

Recreate Search Index

• SearchService.startBackgroundIndex()• Crawlsseedlists• Extractsthefilecontent• Createindex

Tip: Use „all_configured“ to index all apps

CLFRW0394E: Search indexing ofservices ...• Search index not ready

• interruptionatindexcreation• CLFRW0283E:Searchhasencounteredaproblemwhilecrawling

• CLFRW0027E:ErrorIndexingcomponent<app>forsearch

• INDEX.READYfilenotpresent• Recreateandenabletracing

com.ibm.connections.directory.services.exception.DSOutOfServiceException• Access Connections not possible• DSX not working• Check SSO settings

• Domain• LtpaToken Cookiename

Tip: WebSphere FP sometimes resets SSO domain

EJPVJ9284E: Unable to get the groups from the directory for the user…• User was not able to access Connections

anymore• WAS LDAP bind user had no read access

to one of the groups the user was member

Debug wsadmin

• Enable trace within wsadmin session• AdminControl.trace(‘com.ibm.*=all’)• <wasroot>/profiles/<profilename>/logs/wsadmin.traceout

Database connections

• Check datasouces• ISC– Resources– JDBC– Datasources• Checklogsformoreinformation

• DB2 server log• <instanceroot>/sqllib/db2dump/

• db2diag.log• db2diag.xxx.log(logrotation,youshouldenablethis!)

Tip: Oracle users have password expiration enabled by default!

• error_log• access_log• basedonconfiguration

• WebSphere AppServer Plugins• <installroot>/logs/<webserver>/http_plugin.log

HTTP 404 not found

• Outdated Plugin configuration• RestartIHS

• WAS Plugin configuration issue• http_plugin.log

HTTP 404 not found
