Bat dosyasından Oracle servislerini otomatik olarak başlatma/durdurma/devre dışı bırakma nasıl yapılır?

Merhaba,

Bu yazıda .bat komutlarıyla Oracle servislerini nasıl yönetebiliriz ondan bahsedeceğim.

Öncelikle yeni bir .txt formatlı dosya tanımlamalıyız. Örnek olarak oracle.txt olsun.

Daha sonra içine aşağıdaki seçeneklerden birine bakarak komutları ekleyip, kaydedip çıkalım.

Seçenek 1:
rem servisleri kullanılabilir yapmak ve başlatmak için;
sc config OracleServiceXE start= auto
sc start OracleServiceXE
sc config OracleXETNSListener start= auto
sc start OracleXETNSListener

Seçenek 2:
rem servisleri devre dışı bırakmak ve durdurmak için:
sc config OracleServiceXE start= disabled
sc stop OracleServiceXE
sc config OracleXETNSListener start= disabled
sc stop OracleXETNSListener

Son aşamaya gelmeden önce dosyamızın ismini oracle.bat olarak değiştirelim.

Evet, .bat dosyamız çalıştırılmaya hazır. Güle güle kullanın! :)

Bilgi: Bu yazıda, veri tabanı olarak Oracle XE (express edition) kullanılmıştır. Diğer oracle versiyonlarına göre servis isimleri farklılık gösterebilir.

Şuradaki yazıya da bakmanızı tavsiye ederim; http://ozsoyler.blogspot.com.tr/2014/07/windowsda-oracle-xe-service-ve-listener.html

Hoşçakalın :)

RamDisk nedir ve nasıl kullanılır?

Nedir?
RAMDisk, eski tip mekanik hard-disk-lerin okuma ve yazma hızlarının düşüklüğünden bir nebze kurtulmak için kullanabileceğiniz faydalı bir yazılımdır. :) Kısacası; bu yazılım ile bilgisayarınız, fiziksel disk yerine (hard-disk) hali hazırdaki RAM-lerinizi (sanal) disk olarak kullanır.

Kullanımı
Basitçe, tanımladığınz sanal partisyon dizinine çok sık kullandığınız bir programı kurduktan sonra bilgisayarınızda belirgin bir hız artışı sağlanabilir.

Örnek
Google Chrome'da kullanımı;
Web Tarayıcısının, diske kullandığı dizini, yeni tanımladığınız sanal diske ayarlamanız ve aşağıdaki örneğe bakarak yeni bir kısayol tanımlamanız yeterlidir.
"C:\Program Files\Google\Chrome\Application\chrome.exe" --user-data-dir="G:\chrome_userdata"

-- G:\chrome_userdata; sanal disk dizini

Dataram RamDisk yazılımına burada erişebilirsiniz: http://memory.dataram.com/products-and-services/software/ramdisk
