gdump 개요
정의
gdump는 GOLDILOCKS에서 제공하는 유틸리티로써 database가 관리하는 다음과 같은 binary file들을 text 형태로 dump한다.
Control file
Datafile
Log file
Incremental backup file
Property file
Commit log file
Log buffer file
Pending log buffer file
인자
gdump는 필수 인자와 옵션 인자로 구분되어 사용되고 옵션 인자는 덤프하려는 파일의 유형에 따라 다르게 사용된다.
gdump file_type file_name [options]
필수 인자
필수 인자는 파일 유형, 파일의 경로 순으로 사용된다.
file_type: CONTROL | LOG | DATA | PROPERTY | BACKUP | COMMIT_LOG | LOG_BUFFER | PEND_BUFFER file_name: file name to dump
file_type 인자
CONTROL: Control file이다. <GOLDILOCKS_DATA>/wal 에 위치하고, 확장자는 .ctl 이다.
Log: Log file (online/ archived redo log file) 이다. <GOLDILOCKS_DATA>/wal 또는 <GOLDILOCKS_DATA>/archive_log 에 위치하고, 확장자는 .log 이다.
DATA: Datafile 이다. <GOLDILOCKS_DATA>/db에 위치하고 확장자는 .dbf 이다.
PROPERTY: Binary property file을 의미한다. <GOLDILOCKS_DATA>/conf 에 위치하고 파일의 기본 이름은 goldilocks.properties.binary 이다.
BACKUP: Incremental backup file을 의미한다. <GOLDILOCKS_DATA>/backup 에 위치하고, 확장자는 .inc 이다.
COMMIT_LOG: <GOLDILOCKS_DATA>/wal 에 위치한 commit.log 파일이다.
LOG_BUFFER: 메모리에 있는 log buffer를 file로 저장한 것이다. gsyncher를 실행하면 log buffer를 file로 저장한다.
PEND_BUFFER: 메모리에 있는 pending log buffer를 file로 저장한 것이다. gsyncher를 실행하면 pending log buffer를 file로 저장한다.
깨진 control file에 대해 덤프를 시도하면 실패한다.
