AppSync: AppSync-komentoriviliittymän ajoittainen epäonnistuu

Ongelma ilmenee, kun useita AppSync-komentoriviliittymän kirjautumisia yritetään samanaikaisesti. Ongelma on erittäin ajoittainen.

Käyttäjä käyttää AppSync-komentoriviliittymää suorittaakseen palvelusuunnitelman, antaakseen luettelon kaikista kopioista ja lisätäkseen kopion tai poistaakseen sen käytöstä, mutta se epäonnistuu ajoittain.

Palvelusopimuksen suorittaminen epäonnistuu ja tilanne epäonnistuu:

C:\EMC\AppSync\appsync-cli\appsync-cli.bat -login server=xxxxxx port=8445 user=admin password=xxxxxxxx

INFO: Successfully authenticated AppSync!

C:\EMC\AppSync\appsync-cli\appsync-cli.bat -runSP app=filesystem service_plan=xxxxxxx

ERROR: Failed to run SP!

Luetteloi kaikki kopiot, jotka on luotu palvelusopimukselle tai sovellusobjektille epäonnistuu seuraavasti:

C:\EMC\AppSync\appsync-cli\appsync-cli.bat -login server=xxxxxx port=8445 user=admin password=xxxxxxxx

INFO: Successfully authenticated AppSync!

C:\EMC\AppSync\appsync-cli\appsync-cli.bat -listCopies app=filesystem service_plan=xxxxxx age=all

ERROR: Could not locate copies!

AppSync-cas.log, joka sijaitsee kansiossa C:\EMC\AppSync\apache-tomcat\bin, näyttää seuraavat:

AppSync-palvelin kerää luettelon käyttäjälle määritetyistä rooleista todennuksen jälkeen.

AppSync-palvelin kerää roolitiedot todennuksen jälkeen ja kirjoittaa ne avainruutuun (tiedosto muistuttaa tiedostoa) noutaakseen ne myöhemmin.
Kun AppSync-palvelin hakee tallennetut tiedot, ne poistetaan. Jos kuitenkin useita kirjautumisia yritettiin samanaikaisesti, yksi istunto poistaa tiedot, ennen kuin toinen istunto noutaa ne.

Yksinkertaisesti sanottuna tämä on samanaikaisuusongelma, joka johtuu useista kirjautumisista (useampi kuin yksi) samanaikaisesti.

Workaround:
Ongelmaan on olemassa ratkaisu, mutta se edellyttää Dell Technologiesin asiakastuen apua.
