Expression Filter (and the related Rules Manager) are installed automatically with Oracle Database 10g Standard Edition and Oracle Database 10g Enterprise Edition and higher. It is supplied as a set of PL/SQL packages, a Java package, a set of dictionary tables, and catalog views. All these objects are created in a dedicated schema named EXFSYS. Please refer to Oracle® Database Rules Manager and Expression Filter Developer's Guide 11g Release 2 (11.2) Appendix: E Installing Rules Manager and Expression Filter http://docs.oracle.com/cd/E11882_01/appdev.112/e14919/exprn_app_e.htm#EXPRN113 The Expression Filter and related Rules Manager can be seen as installed components in DBA_REGISTRY:
SQL> column comp_id format a16 SQL> column comp_name format a36 SQL> column version format a12 SQL> column status format a7 SQL> select comp_id, comp_name, version, status from dba_registry; COMP_ID COMP_NAME VERSION STATUS ---------------- ------------------------------------ ------------ ------- ... EXF Oracle Expression Filter 184.108.40.206.0 VALID RUL Oracle Rules Manager 220.127.116.11.0 VALID ... 18 rows selected. SQL>
Installing the EXFSYS schema: 1. Login as SYSDBA 2. @?/rdbms/admin/catexf.sql
NOTE: 1. Installing Expression Filter does not automatically install Rules Manager. This component has to be installed separately using the catrul.sql script 2. When reinstalling Expression Filter, you may have to run utlrp.sql to recompile some invalid objects. if this does not help, then to validate the components follow the Note 457861.1
If you dont see (or not found or missing) the Oracle Expression Filter (EXF) or Oracle Rules Manager (RUL) in the dba_registry, then you have to repeat the above steps after running the below scripts, (Refer Note 753041.1)
Restart database with "startup upgrade"
SQL> @?/rdbms/admin/rulpatch.sql Uninstalling the EXFSYS schema: 1. Login as SYSDBA 2. @?/rdbms/admin/catnoexf.sql
NOTE: 1. Uninstalling Expression Filter implicitly uninstalls Rules Manager. 2. The CATNOEXF.SQL script may not drop public synonyms created by catexf.sql. However, with 11.2, it was verified no PUBLIC SYNONYMS for table_owner = 'EXFSYS' were left.
The following script can be used to drop all PUBLIC SYNONYMS created for Rules Manager and Expression Filter when needed:
declare cursor cur1 is select synonym_name from all_synonyms where owner = 'PUBLIC' and table_owner = 'EXFSYS'; begin for c1 in cur1 loop EXECUTE IMMEDIATE 'drop public synonym ' || dbms_assert.enquote_name(c1.synonym_name, false); end loop; end; /
In some versions before 10.2, or if you do not have the dbms_assert package, the following script can be used instead:
declare cursor cur1 is select synonym_name from all_synonyms where owner = 'PUBLIC' and table_owner = 'EXFSYS'; begin for c1 in cur1 loop EXECUTE IMMEDIATE 'drop public synonym "'||c1.synonym_name||'"'; end loop; end; /
The following is a list of the public synonyms that may remain after just running CATNOEXF.SQL and these would be dropped by running one of the above scripts: EXF$INDEXOPER EXF$ATTRIBUTE EXF$ATTRIBUTE_LIST EXF$TABLE_ALIAS EXF$XPATH_TAG EXF$XPATH_TAGS EVALUATE DBMS_EXPFIL USER_EXPFIL_ATTRIBUTE_SETS ALL_EXPFIL_ATTRIBUTE_SETS USER_EXPFIL_ATTRIBUTES ALL_EXPFIL_ATTRIBUTES USER_EXPFIL_DEF_INDEX_PARAMS ALL_EXPFIL_DEF_INDEX_PARAMS USER_EXPFIL_INDEX_PARAMS ALL_EXPFIL_INDEX_PARAMS USER_EXPFIL_ASET_FUNCTIONS ALL_EXPFIL_ASET_FUNCTIONS USER_EXPFIL_INDEXES ALL_EXPFIL_INDEXES USER_EXPFIL_PREDTAB_ATTRIBUTES ALL_EXPFIL_PREDTAB_ATTRIBUTES USER_EXPFIL_EXPRESSION_SETS ALL_EXPFIL_EXPRESSION_SETS USER_EXPFIL_PRIVILEGES USER_EXPFIL_EXPRSET_STATS ALL_EXPFIL_EXPRSET_STATS RLM$EVENTIDS RLM$TABLE_ALIAS DBMS_RLMGR USER_RLMGR_EVENT_STRUCTS ALL_RLMGR_EVENT_STRUCTS USER_RLMGR_RULE_CLASSES ALL_RLMGR_RULE_CLASSES USER_RLMGR_RULE_CLASS_STATUS ALL_RLMGR_RULE_CLASS_STATUS USER_RLMGR_PRIVILEGES ADM_RLMGR_PRIVILEGES USER_RLMGR_COMPRCLS_PROPERTIES ALL_RLMGR_COMPRCLS_PROPERTIES USER_RLM4J_EVENT_STRUCTS USER_RLM4J_RULE_CLASSES
Starting with Oracle Database 12c, the Expression Filter (EXF) and Database Rules Manager (RUL) features are desupported. If you are using Rules Manager, Oracle recommends that you consider migrating to Oracle Business Rules, a component of Oracle Fusion Middleware. The Continuous Query Notification feature of Oracle Database replaces Expression Filter.
