Oracle Java, SmartOS Centos 6 LX branded zone: error while loading shared libraries libjli.so

SmartOS 20150820T062742Z

centos-6 lx-dataset image_uuid b1e082f6-460d-11e5-991a-0bc7df451392 (version 20150819)

I don't know if this happens in other versions or linux distributions.

I've installed Java (using the tar.gz archive downloaded from Oracle). Java 6 and Java 7: same issue.

/usr/java/latest/bin/java: error while loading shared libraries: libjli.so: cannot open shared object file: No such file or directory

Weird:

 # ldd /usr/java/latest/bin/java

lx_vdso.so.1 =>  (0x00007fffff0b0000)

libpthread.so.0 => /lib64/libpthread.so.0 (0x00007ffffee00000)

libjli.so => /usr/java/latest/bin/../lib/amd64/jli/libjli.so (0x00007ffffecf5000)

libdl.so.2 => /lib64/libdl.so.2 (0x00007ffffea00000)

libc.so.6 => /lib64/libc.so.6 (0x00007ffffe600000)

/lib64/ld-linux-x86-64.so.2 (0x00007fffff200000)

Solution:

Create the file /etc/ld.so.conf.d/java.conf and put the following line in it

/usr/java/latest/lib/amd64/jli/

Then run the /sbin/ldconfig command.

# /usr/java/latest/bin/java -version

java version "1.6.0_65"

# ldd /usr/java/latest/bin/java

two new java tools for dicom files

Remember: I'm not a programmer and I'm not a dicom expert.

I've "released" two java "tools" for dicom files.

dcmfileget

https://github.com/alcir/dcmfileget

This tool (as the dcm2txt tool from dcm4che) read a file and print some dicom attributes: patient name, study date, patientid, studyid, studyiuid.

Or if a directory is passed (instead of a single file) it scan each file and print such attributes.

dicomfileCopy

https://github.com/alcir/dicomfileCopy

This tool scan a directory and copy each file to the destination directory creating a path like /destination/study_year/study_month/study_day/patientname_studyi

JAVA cache at System Level

It could be useful to avoid that each user, on a multiuser operating system, have own java cache under his home directory, i.e. a corporate application used by each user. Every time the jnlpi is upgraded, every user have to download the new version in his home directory cache.

Using system level cache, only the first user launching the jnlpi will download the java application in the cache.


vi /usr/java/jre/lib/deployment.config

deployment.system.config file:/etc/java/deployment.properties

vi /etc/java/deployment.properties

deployment.system.cachedir /var/tmp/java/wscache
deployment.system.security.trusted.certs /var/tmp/java/security/trusted.certs

mkdir /var/tmp/java
mkdir /var/tmp/java/wscache


Warning. There will be problems with write and read permission on such directory...

dcmcompare

Java program useful to query two pacs server and compare results. i.e. same number of studies, same patients etc.

dcmold

Java program useful to query pacs server to get scriptable list of studies in a specified time range.
