  • Il comando lsof mostra la libreria in uno stato 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

La libreria si trova in uno stato DEL (non aggiornati descrittori di file di libreria) che impedisce il caricamento della libreria normale. quindi l'errore indica "already loaded in another classloader".

解决方案

(1) Server riavviato per scaricare/ricaricare la memoria: NetWorker RESTAPI non riesce a caricarsi con "Native Library /nsr/authc/webapps/nwrestapi/WEB-INF/lib/librestapi64.so already loaded in another classloader"
(2) Emcauthctomcat.cer importato nel keystore cacerts Java: NetWorker: Certificato emcauthctomcat API REST NetWorker rimosso dal keystore cacerts
