空间数据与索引分开存储管理

在我们使用ArcSDE对矢量数据和栅数据进行存储的时候，有必要将相关的表及索引分开存储。也就是说当用户访问一张表，首先会访问表的索引，然后根据索引来快速定位访问表的内容，那么表与表索引就会占据大量的磁盘I/O资源，从而导致访问表的效率下降。所以我们

在我们使用ArcSDE对矢量数据和栅格数据进行存储的时候，有必要将相关的表及索引分开存储。也就是说当用户访问一张表，首先会访问表的索引，然后根据索引来快速定位访问表的内容，那么表与表索引就会占据大量的磁盘I/O资源，从而导致访问表的效率下降。所以我们应该将表与索引分配在不同的表空间，将不同的表空间存储到不同的磁盘上，这样访问表时，就可以使用不同的磁盘I/O，提高访问效率

步骤一：创建存储矢量、栅格数据及对应的索引存储表空间

create tablespace GISDATA datafile 'D:\GISDATA.dbf' size 1000m autoallocate;

create tablespace GISINDEX datafile 'D:\GISINDEX.dbf' size 1000m autoallocate;

create tablespace RASTERDATA datafile 'D:\RASTERDATA.dbf' size 1000m autoallocate;

create tablespace RASTERINDEX datafile 'D:\RASTERINDEX.dbf' size 1000m autoallocate;

步骤二：设置自增长

-- autoextend
declare
cursor v_file is
select file_id from dba_data_files where autoextensible = 'NO' ;
begin
for v_i in v_file loop
execute immediate 'alter database datafile ' || v_i.file_id ||
' autoextend on next 1024M maxsize unlimited';
end loop;
end;

步骤三：创建sde服务

sdeservice -o create -p sde -d "ORACLE,NJ" -n -i esri_sde -H "C:\Program Files\ArcGIS\ArcSDE\ora11gexe"（具体操作见本博客专题介绍）

步骤四：修改dbtune.sde配置文件

该文件位于sde安装目录下（默认为Program Files\ArcGIS\ArcSDE\ora11gexe\etc下，修改前注意备份原文件）

新增下列参数配置

END

修改完成后保存

步骤五：导入修改好的dbtune.sde配置文件

Sdedbtune -o import -f D:\666.txt -i esri_sde -u sde -p sde -N

步骤六：导入完成后，我们可以利用plsql查看导入结果

select * from DBTUNE t

Arccatalog连接数据库，将数据复制到数据库时，会看到config.keywZ喎?http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">vcmS1xCYjMjA1NDA7xKzIz86qztLDx9DC1Pa1xERBVEFCQVNFR0lTJiMyMDU0MDujqNXise3Kvs7Sw8e1xMr9vt29q7vhuPm+3cDg0M231rHwtOa0orW91eK49iYjMjA1NDA7z8K1xLj3uPa21NOmse2/1bzko6y+zcrHz8jHsL2ousO1xMvEuPax7b/VvOSjqTxicj4KPC9wPgo8cD48L3A+CjxpbWcgc3JjPQ=="file:///C:\Users\ningjun\AppData\Roaming\Tencent\Users\420741948\QQ\WinTemp\RichOle\)TD9%1_QUAU7VWSLA$_X284.jpg" alt="\">

导入完成后，可以通过plsql看这四个表空间数据是不是正常对应存储。
