JTA/XA is a kind of system insurance against data corruption (and the resulting business losses). The most common use cases are: Processing JMS messages from a queue and inserting the results in a database: you don't want a crash to lose messages whose results are not yet stored in the database. Updating two or more legacy back-end systems in the same transaction In general, whenever you access more than one back-end system in the same transaction the use of JTA/XA is highly recommended. Otherwise, the risk of data loss or corruption is too high (and not necessarily visible!). Many programmers try to avoid the "overhead" of JTA/XA by programming application-specific recovery code (such as trying to handle duplicate requests, storing extra state in the database, etc). However, all these approaches are brittle (not reusable, application-specific, and hard to test). In the end, the perceived overhead of JTA/XA is often replaced by equivalent but buggy overhead at the application level.
A sample
Bu kılavuz Debian tabanlı Linux sistemlerde (Debian, Ubuntu, Mint, Pardus gibi) Filebeat ile birlikte ELK (Elasticsearch, Logstash, Kibana) kurulumunu anlatır.
java -version komutu ile sürüm kontrol edilebilir.wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add - komutuylaa Elastic APT deposunun anahtarını sisteme tanımlamak için çalıştırılır.echo "deb https://artifacts.elastic.co/packages/5.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-5.x.list komutu ile Elastic APT deposu sisteme eklenir.sudo apt-get update && sudo apt-get install -y elasticsearch logstash kibana filebeat komutu ile Elasticsearch, Logstach, Kibana bileşenleri ve Filebeat ajan yazılımı kurulur.
Debian tabanlı (Debian, Ubuntu, Mint, Pardus gibi) Linux sistemlerde (paket deposunda bulunmadığı taktirde) JDK8 aşağıdaki adımlar izlenerek kurulabilir:
sudo apt-get install software-properties-common komutu ile (eğer yoksa) add-apt-repository komutuna ilişkin kurulum yapılır.sudo add-apt-repository "deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main" komutuyla Java 8'in bulunduğu paket deposu sisteme eklenir.sudo apt-get update && sudo apt-get install oracle-java8-installer komutuyla Oracle JDK 8 kurulumu tamamlanır.java -version komutu çalıştırılarak sürümün doğruluğu kontrol edilebilir.
