A Installation, Compatibility, and Upgrade

If you are upgrading to Oracle Database 11g, Oracle Spatial is automatically upgraded as part of the operation. For information about the upgrade procedure, see Oracle Database Upgrade Guide.

If you need to downgrade Spatial to the previous Oracle Database release, follow the instructions for downgrading a database back to the previous Oracle Database release in Oracle Database Upgrade Guide.

If you use Oracle Spatial GeoRaster, see Section A.1.

If you are using Spatial Web Feature Service (WFS) or Catalog Services for the Web (CSW) support, and if you have data from a previous release that was indexed using one or more SYS.XMLTABLEINDEX indexes, see Section A.2.

If you need to support geometries with more than 1,048,576 ordinates, see Section A.3.

A.1 Ensuring That GeoRaster Works Properly After an Installation or Upgrade

To use the GeoRaster feature of Oracle Spatial, Oracle XML DB Repository must be installed properly. (In general, you should ensure that Oracle XML DB Repository is installed before you install Oracle Spatial.)

If Oracle Spatial has been installed (such as during an upgrade) but Oracle XML DB Repository is not installed, you need to install the Oracle XML DB Repository and reload related GeoRaster PL/SQL packages. In this case, follow these steps

  1. Install Oracle XML DB Repository.

    For information about installing and uninstalling Oracle XML DB Repository, see Oracle XML DB Developer's Guide.

  2. Go to the $ORACLE_HOME/md/admin directory.

  3. Connect to the database as SYS AS SYSDBA.

  4. Enter the following SQL statements:

    ALTER SESSION SET CURRENT_SCHEMA=MDSYS;
    @prvtgrs.plb
    @sdogrxml.sql
    

A.2 Index Maintenance Before and After an Upgrade (WFS and CSW)

Effective with Release 11.2, the SYS.XMLTABLEINDEX index type is deprecated, and therefore the Spatial WFS and CSW createXMLTableIndex methods create indexes of type XDB.XMLINDEX instead of type SYS.XMLTABLEINDEX as in previous releases. However, if you have data from a previous release that was indexed using one or more SYS.XMLTABLEINDEX indexes, you must drop the associated indexes before the upgrade and re-create the indexes after the upgrade, as follows:

  1. Using Oracle Database Release 11.1, call the dropXMLTableIndex method (in oracle.spatial.csw.CSWAdmin or oracle.spatial.wfs.WFSAdmin, as appropriate depending on the application) to drop associated indexes.

  2. Upgrade the database from Release 11.1 to Release 11.2.

  3. Using Oracle Database Release 11.2, call the createXMLTableIndex (in oracle.spatial.csw.CSWAdmin or oracle.spatial.wfs.WFSAdmin, as appropriate depending on the application) to create indexes that were dropped in step 1.

For information about Spatial Web Feature Service (WFS) support, see Chapter 15, and especially the following:

For information about Spatial Catalog Services for the Web (CSW) support, see Chapter 16, and especially the following:

A.3 Increasing the Size of Ordinate Arrays to Support Very Large Geometries

If you need to support geometries with more than 1,048,576 ordinates, you must follow the instructions in this section. However, doing so involves significant extra work (running a script, migrating existing spatial data), some database downtime , and some considerations and restrictions. Therefore, you should not perform the actions in this section unless you need to.

To increase the size of ordinate arrays to support geometries with up to 10M ordinates, follow these steps:

  1. Ensure that no users are using any spatial tables or Oracle Spatial or Locator features.

  2. Connect to the database as the SYS user with SYSDBA privileges (SYS AS SYSDBA, and enter the SYS account password when prompted).

  3. Enter the following statement:

    • Linux: @$ORACLE_HOME/md/admin/sdoupggeom.sql

    • Windows: @%ORACLE_HOME%\md\admin\sdoupggeom.sql

    One of the actions of the sdoupggeom.sql script is to automatically migrate all spatial data to accommodate the new SDO_ORDINATE_ARRAY definition. This script may take a long time to complete, and the amount of time will depend on the amount of spatial data that exists in the database.

After you perform these steps, the following considerations and restrictions apply:
