docker - ibmcom/db2 컨테이너 실행
"ibmcom/db2express-c"가 이제는 "ibmcom/db2"로 바뀌었다고 합니다.
ibmcom/db2
; https://hub.docker.com/r/ibmcom/db2
위의 문서에도 나오지만, 간단하게는 컨테이너 생성을 이렇게 하고,
c:\temp> docker run --restart=always -itd --name mydb2 --privileged=true -p 50000:50000 -e LICENSE=accept -e DB2INST1_PASSWORD=testpw -e DBNAME=testdb -v db2db_shared:/database ibmcom/db2
db2 명령어를 실행해 볼까요?
# find / -name db2

Command Line Processor for DB2 Client 11.5.7.0
You can issue database manager commands and SQL statements from the command
prompt. For example:
db2 => connect to sample
db2 => bind sample.bnd
For general help, type: ?.
For command help, type: ? command, where command can be
the first few keywords of a database manager command. For example:
? CATALOG DATABASE for help on the CATALOG DATABASE command
? CATALOG for help on all of the CATALOG commands.
To exit db2 interactive mode, type QUIT at the command prompt. Outside
interactive mode, all commands must be prefixed with 'db2'.
To list the current command option settings, type LIST COMMAND OPTIONS.
For more detailed help, refer to the Online Reference Manual.
데이터베이스 목록도 확인해 보고,
// db2 명령어로 확인
db2 => list db directory
System Database Directory
Number of entries in the directory = 1
Database 1 entry:
Database alias = TESTDB
Database name = TESTDB
Local database directory = /database/data
Database release level = 15.00
Comment =
Directory entry type = Indirect
Catalog database partition number = 0
Alternate server hostname =
Alternate server port number =
원하는 DB에 연결한 후,
db2 => CONNECT TO TESTDB
Database Connection Information
Database server = DB2/LINUXX8664 11.5.7.0
SQL authorization ID = ROOT
Local database alias = TESTDB
db2 => select current server from sysibm.sysdummy1

TESTDB
1 record(s) selected.
해당 DB의 테이블 목록도 보고,
db2 => LIST TABLES
Table/View Schema Type Creation time
------------------------------- --------------- ----- --------------------------
0 record(s) selected.
사용자 목록도 확인합니다.
db2 => SELECT * FROM sysibmadm.authorizationids

SYSDEBUGPRIVATE R

암호를 알아낼 수는 없지만, 다음의 명령어로 암호가 맞는지 확인은 할 수 있습니다.
// 정상적인 계정이면,
db2 => CONNECT TO TESTDB USER db2inst1 USING testpw
Database Connection Information
Database server = DB2/LINUXX8664 11.5.7.0
SQL authorization ID = DB2INST1
Local database alias = TESTDB
// 비정상적인 계정이면,
db2 => CONNECT TO TESTDB USER notmy USING testpw
SQL30082N Security processing failed with reason "24" ("USERNAME AND/OR PASSWORD INVALID"). SQLSTATE=08001
참고로 db2 명령어가 이렇게 실패하는 경우,
# /opt/ibm/db2/V11.5/bin/db2
SQL10007N Message "-1390" could not be retrieved. Reason code: "3".
관련 자료를 보면,
DB2START Fails with SQL10007N Message "-1390" could not be retrieved. Reason code: "3"
; https://www.ibm.com/support/pages/db2start-fails-sql10007n-message-1390-could-not-be-retrieved-reason-code-3
환경 변수에 DB2INSTANCE가 없어서 그렇다고 합니다. 그래서 다음과 같이 설정 후 다시 실행하면 정상적으로 구동이 됩니다.
# export DB2INSTANCE=db2inst1
# /opt/ibm/db2/V11.5/bin//db2
