Error description

  • After an upgrade to IBM Sterling B2B Integrator v5020604, the
    property "supportCBCCiphers" is set to "false" in either
    security.properties or customer_overrides.properties file.
    Once that is done, an error "Unable to retreive the key from
    the system. Please contact your system administrator." appears
    in the logs when trying to use SSH user keys. The same error
    appears on screen when trying to check out an SSH user key.
    

Local fix

  • STRRTC - 581032
    nm / nm
    Circumvention:  There is no circumvention at the 5020604 level.
    If the database and file system were backed up prior to the
    upgrade to 5020604, then revert to the old version, then
    upgrade to 5020603_9 instead.
