  • Příkaz lsof zobrazí knihovnu ve stavu DEL:
[root@nw_server ~]#  lsof | grep librestapi64
jsvc       4543 nsrtomcat  DEL       REG              253,2   14881546   67764661 /nsr/authc/webapps/nwrestapi/WEB-INF/lib/librestapi64.so

原因

Knihovna je ve stavu DEL (zastaralý popisovač souboru knihovny), který brání načtení normální knihovny. Proto se v chybovém hlášení zobrazí zpráva "already loaded in another classloader".

解决方案

(1) Restartovaný server pro vyprázdnění/opětovné načtení paměti: Rozhraní NetWorker RESTAPI se nenačte s chybou "Native Library /nsr/authc/webapps/nwrestapi/WEB-INF/lib/librestapi64.so already loaded in another classloader"
(2) Importované úložiště klíčů emcauthctomcat.cer do Java cacerts: NetWorker: Certifikát NetWorker REST API emcauthctomcat odebrán z úložiště klíčů cacerts
