Question

我使用的是最新的Saiku 3.8.3独立版本，我在使用数据库PostgreSQL 9.1时遇到了一些问题，不同的模式就是PUBLIC。

我创建了数据源并且连接正确，这里是我正在使用的数据源而没有个人详细信息：

type=OLAP
name=chegadaturistas
driver=mondrian.olap4j.MondrianOlap4jDriver
location=jdbc:mondrian:Jdbc=jdbc:postgresql://DBNAME:PORT/DB;Catalog=mondrian:///datasources/chegada_turistas.xml;JdbcDrivers=org.postgresql.Driver;
username=postgres
password=PASSWORD
security.enabled=false

我还创建了具有legancy选项的Mondrian Schema，因为我使用了Schema Workbench。这是我创建的Schema：

<Schema name="DEPES" description="DEPES">
  <Cube name="CHEGADAS" visible="true" cache="true" enabled="true">
    <Table name="chegada" schema="fato" alias="chegada">

问题是，当我运行Saiku时，我无法看到架构，并且在日志中出现此错误：

2016-04-08 08:17:31,976 WARN  [mondrian.rolap.RolapSchema] Model is in legacy format
2016-04-08 08:17:36,725 ERROR [org.saiku.web.core.SecurityAwareConnectionManager] Error connecting: chegadaturistas
mondrian.olap.MondrianException: Mondrian Error:Internal error: Reading row count from table [null, null, tempo]; sql=[select count(*) from "tempo"]

所以我注意到COUNT中mondrian使用的select只是表而不是应该在PostgreSQL上使用的schema.table。为了确保我在PostgreSQL公共模式中创建了一个VIEW，并且它没有在“tempo”表中给我这个错误，而是给了我另一个。有没有办法迫使Mondrian在PosgreSQL的选择上使用SCHEMA.TABLE？

问题解决了！看起来当你把Mondrian 3 XML放在Mondrian 4上时（Saiku 3.X使用Mondrian 4）它会升级XML，但它只是“忘记”在更新后放入数据库SCHEMA标签。这是我做的解决方案，感谢Tom Barber（他在Google上的Saiku小组回答了这个问题。

所以只需找到log4j.xml，取消注释（不要重复，它已在文件中注释）：

<appender name="MONDRIAN" class="org.apache.log4j.RollingFileAppender">
     <param name="File" value="${catalina.base}/logs/mondrian.log"/>
     <param name="Append" value="false"/>
     <param name="MaxFileSize" value="500KB"/>
     <param name="MaxBackupIndex" value="1"/>

     <layout class="org.apache.log4j.PatternLayout">
       <param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>
     </layout>
   </appender>

   <category name="mondrian">
      <priority value="DEBUG"/>
      <appender-ref ref="MONDRIAN"/>
   </category>

停止SAIKU并再次启动它。稍等一下，打开saiku.log（它位于“saiku_directory”\ tomcat \ logs \ saiku.log上，搜索一下这样的行：

<Schema name="YOUR_SCHEMA_NAME" missingLink="ignore" metamodelVersion="4.300">
    <PhysicalSchema>
........

复制整个架构并粘贴到新的file.xml上，在所有TABLE标签上插入标签schema =“SCHEMA_NAME”，如下所示：

OLD:
<Table name="chegada" alias="chegada">
NEW:
<Table name="chegada" schema="fato"  alias="chegada">

再次启动SAIKU，上传此架构，重新启动saiku。

问题解决了！：d
