Network Diagrams with Open Security Architecture SVG Icon Set, freeDesktop tango! Icon Library Theme and yWorks yEd Graph Editor on any OS (Linux/Java)

Dear Reader,

I have become an avid user of yWorks yEd Graph Editor. It actually is the best complement for Microsoft's "Visio" that would do the trick for me and runs on Java hence I can use it cross-platform on any OS (e.g. Linux).
Example Graph for Enterprise Manager 12c User Role Concept This is an example graph created with yWorks yEd Graph Editor to show the User Role Mapping in Enterprise Manager 12c.

The latest release is version 3.14.2 which you can download here:
https://www.yworks.com/en/products_yed_download.html


As for me it got my tool of choice - once I found out that to get a good set of icons for my graphs I can use the Opens Security Architecture SVG Icon set and import it into yEd.

See the following steps for a small description of this must-have icon-set in order to realize the full potential of yWorks fantastic Graph Editor.

XML DB Content Connector unable to accept binary content due to Invalid argument(s) in call oracle.sql.BLOB.setBinaryStream(0L)

Dear Readers,


I am working on implementing a custom Document Management System using the Oracle XML DB Content Connector. See the following documentation link for details


Oracle XML DB Developer's Guide 11g Release 2 (11.2)
Chapter 31 Using Oracle XML DB Content Connector

http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_jcr.htm


especially the following example gave me some trouble to run it successfully


Sample Code to Upload File
http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_jcr.htm#ADXDB5627


I had already succeeded to set some of the properties successfully, i.e.
jcr:encoding, jcr:mimeType, ojcr:displayName and ojcr:language.


However
setting the jcr:data property as described in the example failed
consistently, both with the documented input FileStream or with a fixed
string.


contentNode.setProperty("jcr:data", "mystringvalue");

After some research I found the following Support Note which describes the cause for the issue in the JDBC driver version 11.2.0.1.

Error "ORA-17068: Invalid argument(s) in call" Using Method setBinaryStream(0L) in JDBC 11.2.0.1 (Doc ID 1234235.1)
https://support.oracle.com/epmos/faces/DocContentDisplay?id=1234235.1

It can easily be solved by upgrading to JDBC 11.2.0.2 or worked around using the following property setting:


java -Doracle.jdbc.LobStreamPosStandardCompliant=false ...

Kind regards,
Stefan

Troubleshoot ruei-install.sh, Debug RPM Pre/Post-Install Scripts, eg. ux-collector & ux-core rpms


To remove a RUEI system, please follow the steps outlined in Appendix H Removing RUEI From Systems of the RUEI Installation guide.
http://docs.oracle.com/cd/E26370_01/doc.121/e26358/removeruei.htm#BCIECBIB
Usually it boils down to run step number 3.)


Remove the installed RUEI RPMs by issuing the following command as the root user:
rpm -qa | grep ^ux- | xargs rpm -e


If parts of the installed RPMs were removed manually or corrupted, errors might be encountered in the above step.
In this case, you should issue the following command:
rpm -qa | grep ^ux- | xargs rpm -e --noscripts


Note that part of the installation may remain after issuing the above command.


In case you want to troubleshoot the pre/post-scripts the following two commands might be useful, where ux-core is an example rpm file of RUEI:
rpm -Uhvv ux-core-12.1.0.0.1-20120109.x86_64.rpm > OutputOfScripts
rpm -qp --scripts ux-core-12.1.0.0.1-20120109.x86_64.rpm > ListOfScripts


Kind regards,
Stefan

RUEI 12.1.0.3.0 dependency requirement for php-soap-5.1.6

Dear Readers,

please be aware of the new php-soap-5.1.6 dependency in RUEI 12.1.0.3.

For a swift upgrade to RUEI 12.1.0.3 you should be aware of this pre-requisite
as it can be quite difficult to obtain individual rpm-packages inside
of a datacenter for an old OS revision once you have already started the
upgrade.

You may use the following procedure to retrieve the required package via http://public-yum.oracle.com:
