子流程是否是cx_oracle for python的唯一替代方案—连接到oracledb

我在python中使用cx_Oracle已有一段时间了，sqlalchemy也在内部使用它连接到Oracle。但最近，我遇到了一些无法安装cx_Oracle的solaris设备，因此我想知道在子流程中使用sqlplus似乎是运行查询的唯一其他方法

还有其他选择吗

import cx_Oracle
import logging

class Oracle(object):
  """
    Connector class to connect to Oracle database and run queries
  """
  def __init__(self, db_config):
    # mode should be 0 if not cx_Oracle.SYSDBA
    self.logger = logging.getLogger(__name__)
    if db_config:
      self.username = db_config["username"]
      self.password = db_config["password"]
      self.host = db_config["host"]
      self.port = db_config["port"]
      self.sid = db_config["sid"]
      self.mode = int(db_config["mode"])
      self._cursor = None
      self._connection = None
      self.connect_string = self.username + '/' + self.password + '@' + self.host + ':' + self.port + '/' + self.sid
      try:
        self._connection = cx_Oracle.connect(self.connect_string, mode=self.mode, threaded=True)
        self._cursor = self._connection.cursor()
        self.idVar = self._cursor.var(cx_Oracle.NUMBER)
      except Exception as e:
        print "Exception while trying to initialize database connection object : ", e
    else:
      raise DbConfigNotFoundException

  def param_query(self, q, param):
    try:
      self._cursor.execute(q, param)
      return self._cursor.fetchall()
    except Exception as e:
      logger.exception(e)
      raise

cx_Oracle在Solaris上应该可以正常运行。你遇到问题了吗？如果是这样，您能告诉我们有什么问题吗？配置cx\U Oracle很麻烦：cx\U Oracle:ImportError:DLL加载失败：此应用程序失败
