我在打开OrientDB数据库时遇到问题（orientdb-community-1.6.3）。
我可以使用$db = new OrientDB(...)访问服务器。
我可以使用$dbConnected = $db->connect(...)与我的用户管理员联系。
但是打开我的数据库或检查它是否存在会给我一个错误：com.orientechnologies.orient.core.exception.OStorageException: Cannot open the storage 'mydb' because it does not exist in path: /Users/kent/dev/Database/releases/orientdb-community-1.6.3/databases//../databases/mydb
更多详情：
从OrientDB控制台，工作正常：
orientdb> connect plocal:../databases/mydb admin admin
Connecting to database [plocal:../databases/mydb] with user 'admin'...OK
orientDB>
PHP代码段：
$dbInfo = array (
'datasource' => 'Database/OrientDB',
'persistent' => true,
'host' => 'localhost',
'port' => 2424,
'timeout' => 60,
'serverUsername' => 'admin',
'serverPassword' => 'admin',
'database' => 'plocal:../databases/mydb',
'databaseUsername' => 'admin',
'databasePassword' => 'admin'
);
// New OrientDB instance
try {
$db = new OrientDB ( $dbInfo ['host'], $dbInfo ['port'], $dbInfo ['timeout'] );
error_log ( "dbUtil.php:dbOpen: new Orient:db:" . print_r ( $db, true ) );
} catch ( Exception $e ) {
// Report error connecting to server
$exception = 404;
$message .= 'Database server ' . $dbInfo ['host'] . ':' . $dbInfo ['port'] . ' did not respond. ' . $e->getMessage ();
}
if ($db) {
// Made the connection to the server, connect as user $dbInfo ['serverUsername']
try {
$dbConnected = $db->connect ( $dbInfo ['serverUsername'], $dbInfo ['serverPassword'] );
error_log ( "dbUtil.php:dbOpen:dbConnected:" . $dbConnected );
} catch ( OrientDBException $e ) {
// Report error on $db->connect
$exception = 400;
$message .= 'Unable to connect to ' . $dbInfo ['datasource'] . ' as user ' . $dbInfo ['serverUsername'] . '. ' . $e->getMessage ();
}
// Open the database
if ($dbConnected) {
try {
$dbExists = $db->DBExists ( $dbInfo ['database'] );
error_log ( "dbUtil.php:dbOpen(" . $dbInfo ['database'] . "):dbExists:" . $dbExists );
if (! $dbExists) {
// Report database does not exist
$exception = 404;
$message .= "Database " . $dbInfo ['database'] . ' does not exist.';
}
} catch ( OrientDBException $e ) {
// Report err on $db->DBExists
$exception = 404;
$message .= "Error checking the existence of database " . $dbInfo ['database'] . ". " . $e->getMessage ();
}
if ($dbExists) {
try {
$dbClusters = $db->DBOpen ( $dbInfo ['database'], $dbInfo ['databaseUsername'], $dbInfo ['databasePassword'] );
error_log ( "dbUtil.php:dbOpen:DBOpen:dbClusters:" . print_r ( $dbClusters, true ) );
} catch ( OrientDBException $e ) {
// Report error opening database
$exception = 400;
$message .= "Error opening database " . $dbInfo ['datasource'] . ' as user ' . $dbInfo ['databaseUsername'] . '. ' . $e->getMessage ();
}
}
}
}
// Any problems?
if ($exception != 200) {
throw new RestException ( $exception, $message );
}

**更新2014-01-19 ** 将FINEST日志添加到服务器。

连接到服务器后添加error_log ( "dbUtil.php.dbOpen:list of databases:" . print_r($db->DBList(), true));：
[20-Jan-2014 03:06:13 UTC] dbUtil.php.dbOpen:list of databases:Array
(
[docitt] => plocal:/Users/kent/dev/Database/releases/orientdb-community-1.6.3/databases/docitt
[GratefulDeadConcerts] => plocal:/Users/kent/dev/Database/releases/orientdb-community-1.6.3/databases/GratefulDeadConcerts
)
然后使用plocal:/Users/kent/dev/Database/releases/orientdb-community-1.6.3/databases/docitt作为数据库名称。同样的错误：Database plocal:/Users/kent/dev/Database/releases/orientdb-community-1.6.3/databases/docitt does not exist.
答案 0 :(得分：1)
我尝试打开plocal:../databases/mydb的数据库是plocal和graph数据库类型（orientdb-community-1.6.3的当前默认值）。 OrientDB-PHP尚不支持graph数据库类型document :(
