docker - Sybase Anywhere 16 컨테이너 실행
Sybase SQL Anywhere 제품도 현재 공식 이미지는 제공되지 않습니다. 그래서 다음의 이미지를 사용해 볼 텐데,
jaschweder/sybase
; https://hub.docker.com/r/jaschweder/sybase
jaswdr / docker-image-sybase
; https://github.com/jaswdr/docker-image-sybase
docker pull jaschweder/sybase
docker run --name sqlany1 -p 2638:2638 jaschweder/sybase
docker run --name sqlany1 --restart=always -d -p 2638:2638 jaschweder/sybase
실행 후 다음과 같은 로그를 볼 수 있고,
c:\temp> docker run --name sqlany1 -p 2638:2638 jaschweder/sybase

(GUI 도구인 Sybase Central을 포함하는) SQL Anywhere Database Client 프로그램을 이용해,
SAP SQL Anywhere Database Client Download
; https://archive.sap.com/documents/docs/DOC-35857
편하게 DB 구성을 할 수 있습니다.
그런데, 문제는 연결 정보입니다. 분명히 docker hub
jaschweder/sybase 페이지에서는 다음과 같은 계정 정보가 있다고 하는데,
Environment Variables
Guest user
SYBASE_USER guest
SYBASE_PASSWORD guest1234
SYBASE_DB guest
Admin user
SYBASE_USER sa
SYBASE_PASSWORD password
실제로 Sybase Central 프로그램을 이용해 저 계정 정보로 로그인을 하려고 해도 다음과 같이 "Invalid user ID or password" 오류가 발생합니다.
[Sybase][ODBC Driver][SQL Anywhere]Invalid user ID or password
SQLCODE=-103
SQLSTATE=28000
Connection parameters:
User=sa
Password=***
Host=192.168.100.50:2638
LINKS=TCPIP
ENC=NONE
혹시나 싶어 Sybase 문서에 있는,
Starting and connecting to a database on another computer (administration tools)
; http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.help.sqlanywhere.12.0.1/dbadmin/start-connect-another.html
기본 계정 정보를 입력해 보니,
Authentication: Database
User ID: dba
Password: sql
Action: Connect to a running database on another computer
Host: 192.168.100.50
Port: 2638
Server name: (empty) or (demo)
Database name: (empty) or (demo)
잘 됩니다. ^^; 어쨌든, Sybase Central로 접속할 수 있게 되었으니 이후부터는 아래의 글과 동일하게 클라이언트 측 코딩을 작성하면 됩니다.

volume 매핑은, 그냥 감각적으로 다음과 같이 지정했고,
docker run --name sqlany1 -p 2638:2638 -v sqlany16:/opt/sqlanywhere16 jaschweder/sybase
잘 동작합니다. ^^

참고로, "Sybase Central"을 통해 Database를 새로 생성하는 경우, 파일 경로를 "demo.db"와 같은 경로로 잡고 싶다면 "/opt/sqlanywhere16/testdb" 같은 식으로 입력해야 합니다.
CREATE DATABASE '/opt/sqlanywhere16/testdb.db' LOG ON 'testdb.log' COLLATION 'ISO1LATIN1' NCHAR COLLATION 'UCA' JCONNECT OFF;
아쉬운 것은, (demo를 제외하고) 새로 생성한 database가 기본적으로는 원격에서 "시작"할 수 있는 권한이 없어 "Sybase Central"을 통해 다른 컴퓨터에서 접속하는 경우 이런 오류가 발생합니다.
Connection failed.

그래서 미리 container 내부에서 실행시켜 둬야 하고,
c:\temp> docker exec -it sqlany1 /bin/bash
root@ada75548065c:/# /opt/sqlanywhere16/bin64/dbsrv16 -n testdb /opt/sqlanywhere16/testdb.db -x "tcpip(PORT=2639)"

...[생략]...
Trying to start TCPIP link ...
Starting on port 2639
TCPIP link started successfully
Now accepting requests
Press 'q' to shut down the database server
여기서 사용할 포트로 인해 애초부터 container 구동 시 이에 대한 배려를 해야 합니다.
docker run --name sqlany1 -p 2638:2638 -p 2639:2639 -v sqlany16:/opt/sqlanywhere16 jaschweder/sybase
위와 같은 작업이 번거롭다면 사용자 정의 Dockerfile을 만들어 위의 과정을 자동화하는 Entrypoint를 설정하면 됩니다.
Sybase SQL Anywhere로 테스트하는 경우 "Connection limit (licensed seats): 3"이기 때문에 다음과 같은 오류를 많이 보게 될 것입니다. ^^

그리고 테스트를 하다 보면 (트랜잭션 로그를 사용하도록 지정한 DB인 경우) log 파일의 용량이 꽤나 커질 수 있는데, 주기적으로 truncate 시킬 필요가 있습니다.
