Best practice to change admin(wcadmin) password

[SK_10011784]

I am using Windchill PDMLink Release 12.0 and Datecode with CPS 12.0.2.11

Best practice to change admin password (wcadmin)
Solr is also installed in the system, how to verify solr functionality after changing admin password

If your question is asking about how to change it, you can reference the article below. When logged in as wcadmin you can change the password in participant administration.

If your question is asking "What is best practice on how frequently to change admin password?" that would be a question best answered by your security policies. 

As for solr, you can login to the solr UI to validate and also review the indexing administration

Thank you for the information.

One thing we wanted to check is if the WCadmin credentials are used anywhere in Windchill like the solr module and similar cases

What files we need to check to make sure that the password change will not affect any functionality of the system.

Any information on this would be really helpful

Thank you

That depends on how your system was configured. Publishing and indexing could both be using wcadmin; or have separate accounts. The credentials for the publishing user are stored in the auth.properties file.

You need to know where wcadmin is used in your system to know the potential impact of the password changing.

Windchill doesn't need wcadmin password to run.  The account just has to exist in the LDAP and be found by Windchill during startup.  So, a properly configured Windchill system supports password change policies on wcadmin without any extra effort or issues.

Companies shouldn't (but frequently do) use the wcadmin credentials for PTC integrations (SOLR indexing, WVS publishing), third-party integrations, and as the login account to the read-only corporate LDAP.  Start by searching the Windchill load point (xconf and properties files) for 'wcadmin' or '$(wt.admin.defaultAdministratorName)'.  Also look at Apache's app-Windchill-AuthProvider.xml file.

Much less frequently, it is hard coded into customizations.  If you have customizations or custom workflow robots, ask the developer if there are any ties to wcadmin.
