Resolve iManager “503″ issue in Netware
Covered OS versions:
- Netware 5, 5.5, 6, 6.5
- Open Enterprise Server (OES) Netware Kernel 6.5
iManager versions:
- iManager 2.5
- iManager 2.6
- iManager 2.7
Issue:
You have installed Netware, and iManager on your server box. Suddenly, when you tried to access iManager from your browser, you’re greeted with the “Error 503: Service Unavailable” notification.
This is related to how Novell LDAP (NLDAP) and Netware’s server certificates, and how iManager authenticates through LDAP via Apache Tomcat. There’s a possibility that the server certificates are corrupted or the changes that took place for the server certificates were not propagated to the services that need them. Yes, Netware does suffer corruption every now and then due to the nature of the file system it currently uses. It still uses FAT/FAT16/FAT32. This could be resolved by moving to OES-Linux kernel instead of using pure Netware or OES-Netware kernel.
Solution:
We will need to stop Tomcat, Apache web server, and Java. We will then need to rebuild our server certificates. After which we will need to restart our services.
Actual Commands:
On the Netware command line, type the following commands:
NETWARE: tc4stop
(Terminate Tomcat. For Tomcat 5.0, use tc5stop instead.)
NETWARE: ap2webdn
(Shutdown the Apache web server.)
NETWARE: java -exit
(Shutdown Java.)
NETWARE: pkidiag
(This will open the PKI wizard for detecting and repairing public key infrastructure in Netware. Follow the menu items namely 4, 5, 6, 0)
NETWARE: tckeygen
(Restore LDAP connectivity for Tomcat.)After a few minutes, start the services.
NETWARE: tomcat
(You may also use /tomcat/5.0/bin/startup start to start Tomcat 5.0.)
NETWARE: ap2webup
(Start up the Apache web server.)
Try opening your iManager again and login (http://ip_of_your_server/nps/iManager.html)
