  • lsof-komento näyttää kirjaston DEL-tilassa:
[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

Kirjasto on DEL-tilassa (vanhentuneessa kirjaston tiedostonkuvauksessa), mikä estää tavallista kirjastoa latautumasta. virheilmoitus näkyy already loaded in another classloader.

解决方案

(1) Palvelin on käynnistetty uudelleen muistin tyhjentämiseksi/lataamiseksi uudelleen: NetWorker RESTAPI ei lataudu tekstillä Native Library /nsr/authc/webapps/nwrestapi/WEB-INF/lib/librestapi64.so already loaded in another classloader
(2) Tuotu emcauthctomcat.cer Java cacerts -avaintoreen: NetWorker: NetWorker REST API emcauthctomcat -varmenne poistettu cacerts-avainkaupasta
