我目前正在尝试使用 Open-Xchange 配置我的 Ubuntu 服务器以供个人使用。我已经启动并运行了 Open-Xchange（所有数据库和用户都已创建，网站可通过 HTTPS 访问，等等）。
目前，我在创建所需的上下文时遇到了一些麻烦，遗憾的是我找不到有关此问题的任何信息。
这是我正在调用的命令：
createcontext -A oxadminmaster -P '</snip>' -c 1 -u oxadmin -d "Context Administrator" -g Admin -s User -p '</snip>' -L defaultcontext -e oxadmin@myhost -q 1024 --access-combination-name=groupware_standard
我收到以下错误：
context 1 could not be created:
Server response:
The maximum number of contexts in every database cluster has been reached. Use register-, create- or change database to resolve the problem.

似乎 initconfigdb 和 registerdatabase 没有创建任何数据库，我继续创建了一个空数据库：
+--------------------+
| Database |
+--------------------+
| configdb |
| information_schema |
| mysql |
| oxglobal |
以下是 db_pool 表的输出：
+------------+-----------------------------+-----------------------+--------------+----------------+-----------+------+---------+----------+
| db_pool_id | url | driver | login | password | hardlimit | max | initial | name |
+------------+-----------------------------+-----------------------+--------------+----------------+-----------+------+---------+----------+
| 3 | jdbc:mysql://mail.hyhost | com.mysql.jdbc.Driver | openexchange | | 1 | 100 | 0 | oxglobal |
+------------+-----------------------------+-----------------------+--------------+----------------+-----------+------+---------+----------+
我是不是漏掉了什么？我尝试删除 configdb 数据库并调用其安装教程中的所有步骤，但又遇到了同样的问题。
任何有关此事的帮助都将不胜感激。
