Socket timeout in seconds used for communication channel between JK and remote host. If remote host does not respond inside that timeout the JK will generate an error, and retry again. If set to value zero (default) the JK will wait for infinite on all socket operations. 

 Reply_timeout property told webserver to wait some time for reply to a forwarded request before considering the remote tomcat is dead and eventually switch to another tomcat in a cluster group.

Timeout 300
클라이언트의 요청에 의해 서버와 연결이 되었을 때 클라이언트와 서버간에 아무런 메시지가 발생하지 않았을 때 오류로 처리될 시간을 초단위로 설정. 초기값은 1200초(20분)이며 보통은 300초(5분)로 지정한다. 네트워크의 속도가 나쁠수록 수치값은 높게 설정하는 것이 좋다.

WLIOTimeoutSecs 300

  - default : 300 초

  - 웹로직으로 request를 보내고 response를 받기 위해서 대기하는 시간

  - post 방식으로 대량의 데이터를 WebLogic으로 보낼 때 timeout이 발생하면 plug-ins에 "POST_TIMEOUT"에러가 발생한다

Idempotent OFF

cashed는 여유메모리로 보시면 됩니다.

리눅스 시스템은 파일형태로 관리되는 운영체제이기때문에 여유메모리를 캐쉬파일로 표현되고 있습니다.

또한 스왑이란 실제 메모리 캐쉬메모리까지 모두 사용해서, 부족할때 하드 일부분을 메모리 처럼 가져다 쓸때 사용되는 메모리를 말합니다.

free -gt로 보시면 사용되는 스왑메모리는 거의없습니다.

현재 메모리 여유가 있다고 보시면됩니다.
