Perform schema restores of an Oracle enterprise geodatabase

Summary

This article describes a series of steps to perform when importing an Oracle Data Pump file by schema using the Data Pump import utility - impdp. These steps are meant to be run one at a time.

• EGDB: All
• DBMS: Oracle
• DBMS Version: 11g and above

Procedure

1. Create a new Oracle database.
2. Connect as SYS via SQL*Plus.

sqlplus sys/syspassword@server/sid as sysdba

3. Grant public permissions for Oracle geodatabase.

GRANT EXECUTE ON dbms_pipe TO public;
GRANT EXECUTE ON dbms_lock TO public;
GRANT EXECUTE ON dbms_lob TO public;
GRANT EXECUTE ON dbms_utility TO public;
GRANT EXECUTE ON dbms_sql TO public;
GRANT EXECUTE ON utl_raw TO public;

4. Obtain list of owners that own data in the old enterprise geodatabase.

select distinct owner from sde.layers
union
select distinct owner from sde.st_geometry_columns
union
select distinct owner from sde.table_registry
order by 1;

5. Create all required tablespaces.

Note:
This is a default tablespace to auto-extend.

CREATE TABLESPACE SDETBS DATAFILE '/home/oracle/orcl/oradata/banner/sde.dbf'
SIZE 100M AUTOEXTEND ON NEXT 51200K MAXSIZE UNLIMITED EXTENT MANAGEMENT
LOCAL UNIFORM SIZE 320K LOGGING ONLINE SEGMENT SPACE MANAGEMENT MANUAL;

6. Create all required users/schema.

create user sde identified by sdepassword default tablespace sdetbs;

7. Grant all necessary permissions to the new user.

grant CREATE SESSION to sde;
grant CREATE TABLE to sde;
grant CREATE TRIGGER to sde;
grant CREATE SEQUENCE to sde;
grant CREATE PROCEDURE to sde;

grant EXECUTE ON DBMS_CRYPTO to sde;
grant CREATE INDEXTYPE to sde;
grant CREATE LIBRARY to sde;
grant CREATE OPERATOR to sde;
grant CREATE PUBLIC SYNONYM to sde;
grant CREATE TYPE to sde;
grant CREATE VIEW to sde;
grant DROP PUBLIC SYNONYM to sde;
grant ADMINISTER DATABASE TRIGGER to sde;

grant ALTER ANY INDEX to sde;
grant ALTER ANY TABLE to sde;
grant CREATE ANY INDEX to sde;
grant CREATE ANY TRIGGER to sde;
grant CREATE ANY VIEW to sde;
grant DROP ANY INDEX to sde;
grant DROP ANY VIEW to sde;
grant SELECT ANY TABLE to sde;

grant ALTER SESSION to sde;
grant ANALYZE ANY to sde;
grant SELECT ANY DICTIONARY to sde;
grant CREATE DATABASE LINK to sde;
grant CREATE MATERIALIZED VIEW to sde;
grant RESTRICTED SESSION to sde;
grant UNLIMITED TABLESPACE to sde;
grant ALTER SYSTEM to sde;
grant SELECT_CATALOG_ROLE to sde;

8. Create a directory for the SYSTEM user to access.

create directory DPUMP1 as '/home/oracle/dpump';

9. Grant R/W to SYSTEM user to read the files in the directory.

GRANT READ, WRITE ON DIRECTORY DPUMP1 to system;
exit

10. Run the impdp utility from the CMD window for each user schema.

• Example 1: SDE Schema

impdp system/sys directory=dpump1 logfile=sde_imp.log dumpfile=backup.DMP schemas=sde

• Example 2: GIS Schema

impdp system/sys directory=dpump1 logfile=GIS_imp.log dumpfile=backup.DMP schemas=GIS

11. Log into SQL*Plus and check for invalid objects.

sqlplus sys/sys@server/sid as sysdba
Select count(*) from dba_objects where owner='SDE' and status='INVALID';

12. Compile any invalid schema objects.

exec dbms_utility.compile_schema(schema => 'SDE');
