On Windows, when you run the command
-m validate option succeeds, but the following error gets reported towards the end of the command:
c:\Amy_OPAM\Oracle\Middleware\Oracle_RC3\common\bin>wlst.cmd ..\tools\configureSecurityStore.py -d c:\Amy_OPAM\Oracle\Middleware\user_projects\domains\OPAM_RC3_Domain2 -c IAM -m join -p welcome1 -k c:\Amy_OPAM\software\RC3\ -w welcome1 Error: Failed to join security store, unable to locate diagnostics data. Error: Join operation has failed.
Ignore the error. Even though the error gets reported there is no functional impact because the newly created server with the
join option can start successfully and continue to service requests.
