The APR based Apache Tomcat Native library which allows optimal performance in production environmen

[Jiri Pik]

Is this the library built by this script?

cd /usr/local/src/
wget http://mirror.easyname.ch/apache/httpd/httpd-2.4.39.tar.gz 
tar -zxvf httpd-2.4.39.tar.gz
cd httpd-2.4.39
cd srclib

wget http://mirror.easyname.ch/apache/apr/apr-1.6.5.tar.gz 
tar xvf apr-1.6.5.tar.gz
mv apr-1.6.5 apr

wget http://mirror.easyname.ch/apache/apr/apr-util-1.6.1.tar.gz 
tar xvf apr-util-1.6.1.tar.gz
mv apr-util-1.6.1 apr-util


wget http://mirror.easyname.ch/apache//apr/apr-iconv-1.2.2.tar.gz 
tar xvf apr-iconv-1.2.2.tar.gz
mv apr-iconv-1.2.2 apr-iconv

cd /usr/local/src/httpd-2.4.39
./configure --prefix=/opt/httpd --enable-http2 --with-nghttp2=/usr/local/lib --enable-so --with-ssl=/usr/bin/openssl --with-included-apr

make
make install

The outputs of this code are in /opt/httpd/libs.

If so, how do I make the location of the resulting APR libraries know to JIRA?

Dear @Jiri Pik ,

this article will help further.

@Thomas Deiler - thank you.

So I have to manually build this?

And then:

1. Why does not the JIRA / Confluence contain it already?

2. I have to use the version of Tomcat bundled with JIRA/Confluence, right?

3. Once it's built I have to add the path to set-env as -Djava.library.path=/opt/apr/lib?
 

1. Install Oracle java7:

   • sudo add-apt-repository ppa:webupd8team/java
   • sudo apt-get update
   • sudo apt-get install oracle-java7-installer
   • sudo apt-get install oracle-java7-set-default

2. Install tomcat apr:

   • wget http://apache.mirror.anlx.net//apr/apr-1.5.0.tar.gz
   • tar zxvf apr-1.5.0.tar.gz
   • rm apr-1.5.0.tar.gz
   • cd apr-1.5.0
   • sudo ./configure
   • sudo make
   • sudo make install
   • export LD_LIBRARY_PATH='$LD_LIBRARY_PATH:/usr/local/apr/lib'

3. Install tomcat tomcat-native:

   • wget http://mirrors.ukfast.co.uk/sites/ftp.apache.org//tomcat/tomcat-connectors/native/1.1.29/source/tomcat-native-1.1.29-src.tar.gz
   • tar zxvf tomcat-native-1.1.29-src.tar.gz
   • rm tomcat-native-1.1.29-src.tar.gz
   • cd tomcat-native-1.1.29-src/jni/native
   • JAVA_HOME=/usr/lib/jvm/java-7-oracle
   • sudo ./configure --with-apr=/usr/local/apr --with-java-home=$JAVA_HOME
   • sudo make
   • sudo make install

Dear @Jiri Pik ,

to be honest In the past 10 years I had never an issue with tomcat and ARP. Either you have a corrupted binary installation or you modified something.

Where and when did you get aware of ARP in context with Jira?

I just looked at the catalina.log and saw it there as a warning. Googling showed that installing that APR should speed up JIRA, so my answer is YES, I would like to install it. 

Even Atlassian confirms that installing it could speed everything up!

Dear @Jiri Pik 

following your last link:

There is no reason to take any action unless directed to do so by one of our support engineers as a result of a performance issue.

Yeah, you can get from place A to place B either by a horse carriage or by a Ferrari F1 car.

I would prefer the latter.

[Thomas Deiler]

Dear @Jiri Pik ,

pretty fine. You can do it, it is just not recommended. But then please let us know about the performance boost afterwards. Eventually others are also interested.

Eventually this will help measuring the performance before and after:
