TimesTenでユーザを作る〜テーブルの確認まで

Posted at 2014-04-30

先日、TimesTen環境を仮想環境に構築してたけど、それから何もしてなかったので少し進めてみました。
といっても、ユーザを作成して、どんなテーブルがあるかだけですが…

1.sys.odbc.iniファイルとはの巻

TimesTenは、データソース名（DSN）を介して、DBにアクセスを行う
DNSは、TimesTenを識別する論理名（＝Oracleであれば、ORACLE_SIDのこと）
DSNには属性が含まれる（プロパティ的なもの）
Linux/UNIXでは、install_dir/info/sys.odbc.iniファイルに定義される
※このファイルは、別名、システムODBC.INIファイルと呼ばれる

2.TimesTen DBの作成してみるの巻

TimesTenのDBは接続するだけで簡単に作成される
既存DBは初回接続時にメモリにロードされる
DBに接続が確立すると、DBオブジェクトを作成できる
DBは、TimesTenインスタンス管理者のみが作成することができる

実行コマンド

# TimesTenデーモンの起動
	ttdaemonadmin -start

# ↑が起動しない場合
	ttdaemonadmin -force -start

# ステータスの確認
	ttstatus

# ttisqlの起動  ※初回接続時は、ここでDBが作成される
	ttisql

# DSN接続
	connect "dsn=TT_1122";

3.ユーザと権限の管理についての巻

下記のコマンドでユーザを作成する
※通常のOracleと同じ感じ

実行コマンド

# ユーザ作成

create user dacek1112 identified by *****;

実行結果

Command> create user dacek1112 identified by *****;

User created.

Command>

ユーザ作成後、適切な権限を付与する必要がある
- 権限は２種類
  - システム権限
    - DBで複数のオブジェクトにわたってシステムレベルのアクティビティを実行したり、
      特定のタイプの任意のスキーマオブジェクトでアクションを実行できる
    - この権限をもつと、そのユーザに関連するスキーマに表を作成できる
  - オブジェクト権限
    - 特定のスキーマオブジェクトで特定のアクションを実行する
    - この権限を付与されると、表から行の削除ができる
    - オブジェクトの所有者(作成者)には、常にオブジェクトに対するすべての権限がある

SQL文で権限を付与する場合は、GRANT（付与） または REVOKE（削除） を使用する

GRANT
- SQL構文
```
  GRANT {Privilege [,...] | ALL [PRIVILEGES]} TO {User |PUBLIC} [,...]
```
- パラメータ
  
  |項目名|説明|
  |:-----|:---|
  | Privilege|ADMIN
  CONNECT
  CREATE DATASTORE
  DDL
  WRITE
  SELECT
  |
  |ALL [PRIVILEGES]|ユーザーにすべてのTimesTen権限を割り当てる|
  |User|権限を付与するユーザーの名前|
  |PUBLIC|TimesTenインスタンスで現在定義されているすべてのユーザー名、および今後定義されるすべてのユーザー名に権限を付与することを指定|
- コマンド例
```
  GRANT ADMIN TO dacek1112;
```
REVOKE
- SQL文
```
  REVOKE {Privilege [ , ... ] | ALL [PRIVILEGES]} FROM {User |PUBLIC} [,...]
```
- パラメータ
  
  |項目名|説明|
  |:-----|:---|
  | Privilege|ADMIN
  CONNECT
  CREATE DATASTORE
  DDL
  WRITE
  SELECT|
  |ALL [PRIVILEGES]|ユーザーからすべてのTimesTen権限を削除する|
  | User|権限を削除するユーザーの名前|
  | PUBLIC|TimesTenインスタンスで現在定義されているすべてのユーザー、および今後定義されるすべてのユーザーから権限を削除することを指定する|
- コマンド例
```
  REVOKE ADMIN FROM dacek1112;
```
ユーザが作成されたかの確認
