Problem summary

  • DB user account pdmlink had been lockedProbable cause is a Windows update.

  • We have seen this problem with other customers and it occured at the same time with different customers.

Solution

  1. Shut down all Windchill services

  2. Empty logs and caches

  3. Make sure no java (Windchill) is running

Recreate Keystore file

  1. Get passwords for ldap (Windchill DS) and for db-user (in this case pdmlink). Look in app, on server, or ask customer.

  1. Check the file validProperties.list (WINDCHILL_HOME/bin/adminTools/sip/). Make sure you have a hashtag on all rows but:

    • ie.ldap.managerPw

    • wt.pom.dbPassword

    • mapcredentials.admin.adapters

  1. Open a Windchill Shell and run the command:

    • ant -f WT_HOME/bin/adminTools/sip/EncryptPasswords.xml recreateKeyStore

  1. When prompted, enter passwords for ldap, db user, WidnchillLdap, enterpriseldap.
    In this case, same ldap-password for all three instances.
    DB user password was set different

Unlock the db user account:

  1. Run the SQLServer Management Studios and login as SA account

  1. Expand nodes Security > Logins > RMB the db (in this case pdmlink) > select Properties:

  1. In General: Enter Password and Confirm password fields with old password

  1. In General: uncheck Enforce password policy

  1. In Status: uncheck SQL server authentication: Login is locked out

  1. Click OK

  1. Go to Properties for db again and in General: check Enforce password policy and uncheck Enforce password expiration

  1. Go to Status: check that login is locked out is still unchecked.

  1. Click OK

Start Windchill PDMLink

  1. Start services as usual:
    1. PTC Apache/HTTP Server
    2. PTC Windchill Directory Server
    3. PTC Windchill PDMLink
    4. Check logs, etc.. to see that the system starts ok...
