Migrating MS SQL 2005 to Oracle 9i (sqlserver_utilities can't compile)

Question

The package sqlserver_utilities can’t compile. (SQLSERVER_UTILITIES Body Compiled (with errors) )
I am migrating a MS SQL 2005 database to an Oracle 9i database. I have the following installed:
•     Oracle 9i Enterprise Edition Release 9.2.0.1.0 –Production with the partitioning, Spatial, Olap, and Oracle data mining options.
•     Internal to Oracle SQL Developer (client-only) 1.5.0.53.04
•     JTDS JDBC Driver 11.4.4.53.01 oracle.sqldeveloper.thirdparty.drivers.sqlserver
•     Java(TM) Platform 1.5.0_06
The MS SQL 2005 Database consists out of multiple tables, views, stored procedures, functions and triggers. I tried quick migrate only to find that the migration failed.
For a simple migration test I created a test database in MSQL 2005. This database has a simple table with an identity field and a store procedure that does an insert into the table. I followed all the steps to migrate a sql database and everything seemed to work. In Oracle I can now find the migrated table and stored procedure. I also see that the migration tool has created a sequence to deal with the identity field (in combination with a trigger) . when I try to execute the insert stored procedure in Oracle it fails. When I started looking at the log messages I see:
INSERT INTO "DBO_STOREDPROCEDURETEST"."SOMEOTHERTABEL" (SOMEOTHERTABELTEXT, SOMEOTHERTABELCODE, VERYBASICTABLEID) VALUES ('sdfgsdfg', 'sdgfsdfg', '1')
One error saving changes to table "DBO_STOREDPROCEDURETEST"."SOMEOTHERTABEL":
Row 3: ORA-04068: existing state of packages has been discarded
ORA-04063: has errors

ORA-06512: at line 1
I then noticed the sqlserver_utilities package compiled with errors. It seems that DBMS_DB_VERSION.VER_LE_9_2 and REGEXP_INSTR doesn’t exists. (see code beneath)
-- only for 10g
IF NOT DBMS_DB_VERSION.VER_LE_9_2 THEN
IF REGEXP_INSTR(temp_exp,
'^\{d[[:space:]]*''([[:digit:]]{4})-([[:digit:]]{2})-([[:digit:]]{2})''\}$') = 1 THEN -- ISO861 format
-- e.g. {d '2004-05-23' }
temp_exp := REGEXP_REPLACE(temp_exp,
'^\{d[[:space:]]*''([[:digit:]]{4})-([[:digit:]]{2})-([[:digit:]]{2})''\}$',
'\1-\2-\3');
format_str := 'YYYY-MM-DD';
Question 1: How do I solve this problem? (the oracle database must be Oracle 9i)
Question 2: How can I migrate an MS SQL 2005 DB to oracle 9i ? (with views, triggers, stored procedures )

Hi user640306,
FUNCTION str_to_date(p_date_expr IN VARCHAR2)
RETURN DATE
has the 10g regexp code
IF format_str IS NOT NULL THEN
RETURN TO_DATE(temp_exp, format_str);
ELSE
RETURN TO_DATE(temp_exp, 'DD-MON-YYYY HH24:MI:SS');
END IF;
It defaults to 'DD-MON-YYY HH24:MI:SS' I suggest altering the code to suite how you want string to date to work in your locale.
FUNCTION str_to_date(p_date_expr IN VARCHAR2)
RETURN DATE
IS
temp_val NUMBER;
temp_exp VARCHAR2(50);
format_str VARCHAR2(50) := NULL;
BEGIN
IF p_date_expr IS NULL THEN
RETURN NULL;
END IF;
temp_exp := TRIM(p_date_expr);
-- only for 10g code removed this was trying
-- to work out the date mask using regular expressions.
IF format_str IS NOT NULL THEN
RETURN TO_DATE(temp_exp, format_str);
ELSE
--If you use this code insert an appropriate data mask,
--default is  'DD-MON-YYYY HH24:MI:SS'
RETURN TO_DATE(temp_exp, 'DD-MON-YYYY HH24:MI:SS');
END IF;
EXCEPTION
WHEN OTHERS THEN
RETURN NULL;
END str_to_date;
