Portable paths and PHP CLI - path

So I got burned again by forgetting that the CLI does not have $_SERVER['DOCUMENT_ROOT'] defined.
What is the best way to get a portable/relative path in a PHP script that will be run by cron?


you mean such as:
$thePath= dirname(__FILE__);

Get HostName in .jtl file in Jmeter

I am using ANT (build tool) to run jmeter functional scripts. I want to get the hostname or website name where all my jmeter scripts are running.
I have checked the jmeter.properties file to do some changes but no luck but no luck.

I fixed and I want to share solution.
I have uncommented the configuration in jmeter.properties.
jmeter.save.saveservice.hostname=true
so that the hostname will be written to the jtl file and from the jtl file, i got it by xpath as below,
/testResults/httpSample/#Host
Thats it, you can use this as xsl variable for reporting or for any purpose.

You can use below inbuilt functions in JMeter.
${__machineName} - to get the machine name
${__machineIP} - to get the IP address

Grails: how to define configuration profile when launching grails war with java command?

I have a grails 3.0 application packaged as war file, and I would like to run it with java command line. Things looks simple from the reference guide: java -jar my_war_file_name. But I cannot find a way to pass in the profile (dev/test/prod), and also it looks like -D option cannot overwrite the configuration as well. Any idea?
Best Regards

Sorry, I found the problem. I should put -D in front of -jar. So this is working:
java -Dgrails.env=prod -Dserver.port=xxxx -jar my_war_file

Using TDBLoader in JENA

I'm trying to learn how to use TDBLoader using this example I found:
https://github.com/ijdickinson/jena-tdb-ont-example
However, when trying to run the init-demo script, I keep running into issues
https://github.com/ijdickinson/jena-tdb-ont-example/blob/master/src/main/script/init-demo
I'm using cygwin to attempt to run the script, but I keep getting please ensure $Path contains $TDBROOT/bin
I set TDBROOT= C:\Development\apache-jena-2.12.1
And my Path has "%TDBROOT\bin"
I'm really new to using command line and shell scripts, so I'm not at all familiar with how to go about debugging this.
I have my tdbloader in apache-jena-2.12.1\bin , is there a way I can check if this is even working? Or if my path is properly set?
I tried "tdbloader" and "-v tdbloader" in command line and I get "tdbloader" is not recognized...
That's not supposed to happen if my path is set correctly, right?

Jenkins service start error on red hat linux

The jenkins service does not start when ever i run jenkins service start . It says
Starting Jenkins bash: /usr/bin/java: No such file or directory
[FAILED]
I have java installed at /usr/lib/jvm/jdk1.7.0_51. The JAVA_HOME variable is also set. Also tried adding this java to /etc/init.d/jenkins file. I need to use the sun jdk, not open jdk.
Tried some of the alternatives from stackoverflow as well but did not work out.
Any suggestions will be of great help.
Thanks,
Bhargav

Thanks Paul. The script inside /etc/sysconfig/jenkins needs to be edited. Else it uses the default java.
JENKINS_JAVA_CMD="path of java installation"
Along with the above script, one can make changes to /etc/init.d/jenkins file if needed to add the path of java installation in your system.

I'd guess that there's a script that has /usr/bin/java hardcoded. When you find the culprit, remove the /usr/bin so that it uses the default. Or you can change it to use the JAVA_HOME path, something like this:
JAVA_EXECUTABLE=$JAVA_HOME/bin/java
$JAVA_EXECUTABLE $JAVA_OPTS etc.. etc..

In SQLplus, is there a way to execute a file by using an environment variable?

I am using sqlplus on a windows environment. At the moment i run sqlplus from a specific directory. I have several scripts that are in several places on my machine. Here are example commands i use within sqlplus to execute some of these scripts.
sqlplus> #../../scripts/oracle/viewdbajobs.sql
sqlplus> #../../../../../devhome/admin/scripts/listinactiveusers.sql
sqlplus> #../../../../../../../web/app/testscript.sql
its quite annoying to have to type all that just to access a directory. I am thinking if i can configure several environment variable for each location i can then do something like this
sqlplus> #$ORACLE_SCRIPTS/viewdbajobs.sql
sqlplus> #$DEVHOME_SCRIPTS/listinactiveusers.sql
sqlplus> #$WEB_HOME/testscripts.sql
Is the above possible? If not, is there a better alternative approach?
Thanks

ok ive found out that this actually works.
sqlplus #%DEV_HOME%/test.sql
Thanks
