ZYLK INDUSTRY wants to accelerate its growth via BIND 4.0

 

Last Friday, September 16th the spin-off of ZYLK ZYLK INDUSTRY asked to join in the accelerator BIND 4.0.

 

 

BIND is the first startup accelerator offering access to high-level Industry 4.0 customers as you can read at their website.

Bind 4.0 is a public-private acceleration program that lasts 24 weeks and takes place in the Basque Country. It focuses on Industry 4.0 early-stage startups involved in big data, additive manufacturing, artificial vision, cloud computing, augmented reality, cybersecurity, cyberphysical systems and/or collaborative robotics.

They offer “A contract with one of our top industry firm partners for the development of an Industry 4.0 project.” and that is what we wanted the most. We already work for some of this companies on BigData applied solutions but we want to go further offering to Industry and IoT solutions.

We hope to find mentoring, support services, networking and our next contract from companies as CAF, CIE Automotive, CAF, Iberdrola, Euskaltel, Dannobat Group, Michelin, Repsol Petronor, ITP or ABB.


ZYLK Industry solution is based on the combination of the two most promising techniques in Industry 4.0: 360º data acquisition plus advanced analytics with BigData technology.

your industry is full of data, are you aware of that?

 

 

ZYLK Industry is a project that was born 2 years ago from the Big Data Team experience in Energy, Automotive, and Telecomunications industries. Our team is formed by professionals with extensive experience in Big Data, IoT, telecommunications, front-end interfaces and data analytics.

ZYLK Industry has given a step foward and has developed a non-intrusive 360º data adquisition device, M2M, endowed of distributed intelligence through which, upon captured data, we established a layer of advanced analytics and visualization that allows showing the process KPI’s and generating alerts. With this, we optimize patterns of energy consumption, reduce peak power demand, improve the OEE and enable cost reduction.

Beyond the applications that offer Analytics for Big Data, ZYLK Industry provides hardware and software solutions based on Hortonworks (zylk is already partner), Kaa project and Apache Hadoop Ecosystems, to  implement energy saving measures to the industrial sector.

Watching your Libreoffice process for Alfresco transformations
A usual question of final users is that their Office files are not being previsualized in Alfresco. This may be for some reasons like:
 
 1. The office file is corrupted
 2. The office mimetype is not set correctly
 3. The office file is too big
 4. The Libreoffice process is not responding
 
In the last case, you will see that new MS-Office and Office documents are not being previsualized (any of them). In that cases, the first thing you should do is to check the Libreoffice process, by default in 8100 port:
 
  ps aux | grep soffice
 
If this process does not exist, or it seems to have problems, the manual solution is to restart Libreoffice just with a simply:
 
  $ALF_HOME/alfresco.sh start libreoffice
 
Sometimes it is necessary to kill the pid of the Libreoffice process, previously.
 
But there are better alternatives for the Alfresco admin. The first one is based on a nice plugin and a quartz job:
 
 
where you can define the corresponding cronjob in alfresco-global.properties
 
contentreich.officeWatchDog.kill=true
contentreich.officeWatchDog.cronExpression=0 */10 * * * ?
contentreich.officeWatchDog.timeoutSeconds=60
 
Another simple solution is check_libre.sh script in the crontab:
 
#! /bin/bash
# m h  dom mon dow   command
#0,15,30,45 * * * * /opt/alfresco/bin/check_libre.sh
 
ALF_HOME=/opt/alfresco
ALF_EXE=$ALF_HOME/alfresco.sh
ALF_LOG=$ALF_HOME/tomcat/logs/libreffice.log
ALF_DATE=`/bin/date`
 
if [[ -z `/bin/pidof ".soffice.bin"` ]]
 then
  $ALF_EXE start libreoffice
  echo "$ALF_DATE" >> $ALF_LOG
fi 
 
The log will help you to track if you have many problems with Alfresco transformations and OODirect subsystem. If this happens, consider to have memory enough for the soffice process.
 
You can also use the next script for reference for starting Libreoffice:
 
 
And finally, in Enterprise Edition (although in this case, it is tracked via Jodconverter subsystem) you can also restart the Libreoffice subsystem via JMX, or to set multiple instances to jodconverter via Admin Console.
 
 
NOTE: In Alfresco 5.1.e you need to change alfresco.sh to the correct location of libreoffice script (assuming an installation with the linux installer and including libreoffice). Anyway you can always run:
 
zylk@alf5:/opt/alfresco51e/libreoffice/scripts$ sh libreoffice_ctl.sh start
libreoffice_ctl.sh : libreoffice started at port 8100
 
In alfresco.sh change:
 
#LIBREOFFICE_SCRIPT=$INSTALLDIR/libreoffice/scripts/ctl.sh
LIBREOFFICE_SCRIPT=$INSTALLDIR/libreoffice/scripts/libreoffice_ctl.sh
 
Also the libreoffice_ctl.sh script needs to remove the slashes. Check this:
 
 
NOTE II: In Ubuntu you may also need:
 
sudo apt-get install libice6 libsm6 libxt6 libxrender1 libfontconfig1 libcups2 libxinerama1 libglu1-mesa
My top Alfresco Addons
Recently we upgraded to Alfresco 201602GA (5.1.e CE) with all their new capabilities such as smart folders, new admin console or model manager. But once you installed Alfresco CE (or EE), you always need some extra Community power. This is a selection of our favourites for our Alfresco installations.
 
1. Javascript Console: Simply fantastic, essential plugin for administrators and developers in Alfresco installations. 
 
 
Also execute script addon in Share extras is quite useful in 5.x version , but it needs some changes for make it work in recent versions
 
2. Alfresco Site Creators: I do not remember a recent Alfresco Installation without this customization. Must have!
 
 
 
3. Alfresco Site Space Templates: The missing templates for Alfresco Sites.
 
 
 
4. Libreoffice Edit Online: No applet based, simple as webdav based edition hyperlink for protocol registering.
 
 
 
5. Uploader Plus: How many times does a client ask you for filling metadata before uploading the document ? 
 
 
 
6. Alfresco List Manager: Dynamic Lists administration for your Alfresco Share forms and content models. A simple way for avoiding redeploying constraint lists in content models continuously. It is very useful, when these data is not completely static, for example a list of clients.
 
 
 
 
7. Alfresco Bulk Import v.2.0: Enhanced Bulk Import Tool for (not inplace?) content migrations.
 
 
 
8. Trashcan Cleaner: Do no forget to take out the thrash.
 
 
 
9. PDF Toolkit: Useful PDF actions for content rules split, merge and many more.  
   
 
 
10. Alfresco Audit Analysis and Reporting: The BI reference project for Alfresco Suite.
 
 
For Alfresco 4.x users Audit Share is a very very nice addon --> https://github.com/atolcd/alfresco-audit-share
 
 
11. Alfresco Groovy Runner: Nice console for accesing Alfresco Java API. Well documented, with many examples.
 
 
 
12. Alfresco version by name: Very nice customization for the default behaviour when uploading documents in Share. 
 
 
 
Other admin basics for EE users are:
 
 
1. Support Tools for Enterprise Edition: A "must" have for every Alfresco Enterprise installation.
 
 
A JMX console like JMX term is quite useful --> http://wiki.cyclopsgroup.org/jmxterm/
 
 
2. Alfresco Nagios Plugin: A very useful check_jmx plugin for Alfresco (more adequate for Enterprise Editions) although basic ports monitoring and checks are also valid for Community Edition.

Change Alfresco ports in Alfresco 5
Sometimes we need to change the main ports of an Alfresco web application (i.e 8080 --> 9080), for example for running another Tomcat based app in your machine. This is a tip for Alfresco 5.x
 
* Change 8080, 8443, 8009 and 8005 connector ports in $ALF_HOME/tomcat/conf/server.xml
 
* Change JPDA 8000 in  $ALF_HOME/tomcat/bin/catalina.sh if used
 
* Change 8080, 8443 ports in $ALF_HOME/tomcat/shared/classes/alfresco-global.properties
 
  alfresco.port=8080
  share.port=8080
  solr.port=8080
  solr.port.ssl=8443
 
* Change 8080 ports in $ALF_HOME/tomcat/shared/classes/alfresco/web-extension/share-config-custom.xml urls (at least 5 urls by default)
 
* Change 8080 and 8443 in: 
 
  alfresco.port=8080
  alfresco.port.ssl=8443
 
  $ALF_HOME/solr4/workspace-SpacesStore/conf/solrcore.properties
  $ALF_HOME/solr4/archive-SpacesStore/conf/solrcore.properties
 
In Alfresco 4.x (with SOLR 1.4) you need :
 
  $ALF_HOME/alf_data/solr/archive-SpacesStore/conf/solrcore.properties
  $ALF_HOME/alf_data/solr/workspace-SpacesStore/conf/solrcore.properties
 
If for any reason you have to run two Alfresco repositories in the same machine, you may have other port conflicts relating RMI (50500), FTP (2121), CIFS (1445,1137-1139), IMAP (1443) , SMTP (25), Hazelcast (5701) or Libreoffice (8100). You may need to check this:
