Cause

Unsupported modification happened on the control station in relation with Java Run time (JRE) RPM package

Resolution


It appears like, customer installed a newer version of Java JRE which resulted in recreation of /usr/java/lib/i386 folder. This made 2 symbolic links to miss and caused the reported error of : java.lang.UnsatisfiedLinkError

2 Files that is required are :

lrwxrwxrwx 1 root root 26 Nov  7 14:11 /usr/java/lib/i386/libdb_java-4.5.so -> /nas/lib/libdb_java-4.5.so
lrwxrwxrwx 1 root root 30 Nov  7 14:11 /usr/java/lib/i386/libmultibyte.so -> /nas/stats/lib/libmultibyte.so

After recreating the links of both, it successfully worked.

To recreate:

[root@CS0 nasadmin]# ln -s /nas/lib/libdb_java-4.5.so /usr/java/lib/i386/libdb_java-4.5.so
[root@CS0 nasadmin]# ln -s /nas/stats/lib/libmultibyte.so /usr/java/lib/i386/libmultibyte.so

Now it will work correctly:

[root@CS0 nasadmin]# nas_stats  -groups -list
Type                Name
System            basic-std
System            caches-std
System            cifs-std
System            cifsOps-std
System            diskVolumes-std
System            metaVolumes-std
System            netDevices-std
System            nfs-std
System            nfsOps-std

If the issue is complex, CS recovery need to be done.

Additional Information

Typical Java locations are as below (from a 8.1.9.184 box this is from, based on code, this will vary with JRE version number):
