Ingres to Oracle 9i

This forum states it is for "Ask any questions regarding migrating from non Oracle Databases, report problems and request enhancements to the Oracle Migration Workbench", so I hope there may be some help for a migration I'm being asked to make from CA-OpenIngres 2.0 to Oracle 9i. I have Ingres DBA skills, but I am a novice with Oracle.
Are there any documents, migration guides or other resources to help me make a such a migration? If I use Ingres utilities to create the SQL that Ingres would use to move the database to another Ingres instance, would such a script probably run with Oracle?

There should be an unsupported Migration Kit for Ingress on OTN.
Click on "Oracle Migration Toolkits" under the "Migration Home" section in the Oracle "Migration Technology Center" on OTN.oracle.com, and scroll down to see Ingress toolkit.

Ingres to Oracle Migration (Database Events)

I am currently working on an Ingres II to Oracle 8.1.6 migration
project. The client OpenROAD 3.5/03 application makes extensive
use of Ingres database events.
Put simply we have a single master process which services
requests for orders from a number of child processes. There is a
desire to minimise the degree of code changes when migrating the
application. OpenROAD provides the
DBSessionObject.RegisterDBEvent and RaiseDBEvent methods which
make underlying calls to the Oracle DBMS_ALERT package.
The problem we have stems from the fact that Ingres database
events are broadcast to all sessions registered as having an
interest, much like the Oracle alerts. However, Ingres events
are retained in a queue whereas the Oracle alert messages, if
unread, are simply overwritten.
I feel the best solution would probably be to use the Oracle
DBMS_PIPE package and build dedicated pipes between each
master/child session. However, OpenROAD does not appear to
provide an interface to this package.
Does anyone have experience of this problem or have any
suggestions? I'm looking for information on how other sites have
successfully migrated between the two products. I did find a
migration toolkit but it seems to avoid the issue of database
events.
Many thanks,
Max

hello,
I am interested on the architecture which you set up to see how
you reach a base ORACLE from OPENROAD or ABF applications. Have
you planned to pass in OPENROAD 4.1? do you know the GATEWAY CA?
Thanks in advance,
Didier

Attempting to create 2nd instance and links for Ingres to Oracle conversion

I have an oracle instance called ORCL that was set up with a DB link to the Ingres Database and it works. I want to create
a second instance using the same binaries so that I don't clobber a developer. Using DBCA I created CONVERT.
Here's were my memory is faulty as to how the first instance was set up. I create a db link, and also entries in the
ORACLE_HOME\hs directory for the init.ora I have one listener running at it lists both instances in the sid_list ...
then when I try to query the ingres database I get
ORA-28500: connection from ORACLE to a non-Oracle system returned this message: [Microsoft][ODBC Driver Manager] Data Source name not found and no default driver specified.
ORA -02063: preceeding 2 lines from SDFA_INGRES
My oracle Database is on Windows. This is Oracle 11
ORACLE_HOME is F:\apps\oracle\product\11.1.0\db_1\ for both ORCL and CONVERT

My select is from the CONVERT instance as SYS ...
select count(*) from test_table@SDFA_INGRES;
and then I get the above error.
What am I missing or have wrong ? Can I have 2 HS services defined in one listener or do a need seperate listeners ?
Appreciate all assistance. Excuse my typing errors ... I am on a another system and can't cut and paste. So I might have
some typos ... thank you.

Andy:
That's was it !!!! I had forgotten that we needed to do this ...
I still have one little ouch though....
When I bring up the driver to define it..... on the DataSource Panel, it asks for a VNODE. It gives me 2 drop down
items which are neither of the systems I want. I can't seem to over write this value ...
Any idea of how to get my system in the VNODE field ? I can ping the box that I want to get to from the system.
I have the IP address .. where does this get set ? Every thing else seems to be good.

How to migrate Ingres to Oracle?

Hi,
I'm going to migrate an Ingres 6.4.05 which is now running in
DNX 6000 machine to an ORACLE database, and if possible into an
oracle8i. I understand that Oracle Workbench doesnt support this
migration procedure. So, is there any other tools or third-party
product which can help me achieve this?
Any feedbacks and suggestions are greatly appreciated. Thanks.

Hi,
There are some toolkits (unsupported now) that may help you with
your conversion.

able to assist you

Ingres vs Oracle exclusive locking

Ingres allows an exclusive lock on tables, set lockmode on tablename where readlock = exclusive which means the users can't access the same
rows that are being modified by another query.
Is there anything in oracle that does the same thing ? All of Oracle's locking seesm to be that you can
still read data. And that is what my user is afraid of. He doesn't want to read old data, when it's
being changed.
How do you work around this ?
Thanks.

It could be that the SID and SID_NAME is wrong.
Check SID=tg4ingr and SID_NAME=tg4ingr instead of SID=ingres

Sun T2 chips vs SPARC64 VI/VII chips for Oracle database servers

We have recently found poor performance of Sun T5240 servers where (against previous V series servers with similar gross I/O capabilities on the disk volume)the timings for the recovery of the database, and the subsequent re-build of the tables and materialised views, are variable from slightly worse to atrocious. Given that the clock-speed is similar,and all significant oracle database parameters are the same, we couldn't see why these processes should take longer on the T5240. The statistics report from the database showed no I/O bottleneck on the new machine, instead it showed raised CPU times for some of the key slow statements.
We found the attached oracle metalink document (ref 781763.1) <<Sun_T2_slow_for Oracle_DB.html>>
Seems to be that if you can't control the content of large long-running SQL statements to parallelise them, don't buy a T-series box as the multithreading capability will work against you.
Therefore we are looking at new servers to run other similar large Oracle apps and appear to have a number of choices within a similar price range
Notably
M3000 - 1 x SPARC VII CPU (quad core procesor)
M4000 - 2 x SPARC VI CPU (dual core processor)
as opposed to the
T5240 - 2 x T2 CPU (8 core processor)
Question is which of these CPU/Core combinations works best...are there performance figures? What's the difference between CPU's and number of cores?
Any benchmarks to help us decide? Anyone experienced similar or tried these different combos for themselves?

We tested a T5210 as a database server (running Ingres, not Oracle) and our batch performance was roughly equivalent to a dual CPU UltraSPARC III V480. Our guess is that the performance hit came from having a relatively small cache shared across so many threads. Like you, we're looking at using the M3000 or M4000 in preference.

Looks like its actually connecting ok, as it includes the message "Created new ODBC connection (16585544)"
The ODBC driver is from CA (ingres) v3.5
- not sure that this fully supports all the requirements specified in the doc, and its not very well documented.
- the latest version available from their website is 2.8 which has some docs to say what it supports:
"The Ingres ODBC driver is a 2.x ODBC driver that supports all core and level 1 functions plus the following level 2 functions:
SQLExtendedFetch (through Microsoft Cursor Library only)
SQLForeignKeys
SQLMoreResults
SQLNumParam
SQLPrimaryKeys
SQLProcedureColumns
SQLProcedures
SQLSetPos (through Microsoft Cursor Library only)"
In order to test the configuration, I also copied the entries in the tnsnames and listener files, created a separate DSN, and set up a connection to an Access database - and this works fine, so I don't believe it is a configuration problem.
Is there anyone out there who has tried to connect to ingres, and is there an issue with the ingres ODBC driver.
Any help appreciated.
Leo

I'm using the Ingres 2.80.00.64 driver on NT successfully with hsodbc delivered with V92 Oracle database release.
About the provided trace file... Normally you should have a look at the odbc driver AND the hsodbc log file to see the real cause.
But according t the file you provided:
This error is normal: [G000]
The S1009 needs more clarification and thus an ODBC driver trace would help as well.

INGRES 6.4 ESQL/Fortran to Pro*Fortran

Is there any tool kit to convert Embedded SQL fortran programs
of Ingres to Oracls Pro Frotran.
Thank

Hi Raja,
There are white papers and also some migration toolkits available
for download from OTN. You can go to the Technology/Migration
section and then to Migration Toolkits, and click under Ingres.
But I am not sure if you will find anything for conversion for
ESQL Fortran.
Thanks,
Srini.

Comparintg times in a dynamic sql statement

I am working on a coversion procedure from one database to another. I have a move procedure that calls functions and the like .
I am trying to use dynamic sql and my where clause is giving me errors. What am I missing here ? TIA....
DEFINE DATECUTOFF ='11-JAN-05' of type date
DES_DATE is a date column in the 2nd database .... type date
I am building strings to do a create table from the 2nd database ...
Testwhere := q'[where to_char("des_date", 'DD-MM-YY') < '01-JAN-05]'; === works but I want to pass in date variable
Teststring := 'Create table '|| table_name || ' as select * from '|| second_table||'@'Linkname
execute immediate teststring || ''|| testwhere;
Testwhere := q'[where to_char("des_date", 'DD-MM_YY') < to_char(DATECUTOFF, 'DD-MON-YY')]; gives me errors like invalid number, or invalid type depending on where the quotes are or how I define DATECUTOFF
Any ideas of what I am doing wrong in comparing the two dates ?
Thanks.

Sorry if I confused anyone ... we're working a duo effort here and get confused ourselves. Here's a summary of the effort.
We're on 11G Linux.
We're writing scripts, procedures and functions that will help us transition from a remote database (Ingres) to oracle. We plan to do this for many dbs, so we are using variables for the table names, links, etc ....
The Where clase that we are developing is pretty
complex, so our initial attempts to build it is
to make it into two sections as a "literal" , join them and do a execute immediate. A date fields seem to be the issue...
Our main procedure calls a datamove function to do the select from the remote data base....
DATECUTOFF is date;
TESTWHERE is varchar2(600);
TESTSTRING varchar2(600);
TestString := 'Create table '|| table_name_temp|| as select * from '||remote_table_name||'@'Linkname;
TestWhere :=q'[ Where ||des_date < 'DATECUTOFF'];
execute immediate Teststring || '' ||Testwhere;
Can I do this in dynamic plsql ? the des_date is the column from the remote database. DATACUTOFF comes from the main procedure passed in.
I do a DBMS_OUTPUT.Put_Line{teststring);
DBMS_OUPUT.Put_Line(testwhere);
and get the following on my screen
Create Table AC_KEY_TEMP as select * from ACK_KEY2@DBLINK2
where "des_date" = 11-Jan-05
DECLARE
Error at line 1;
ORA-00904 "JAN" invalid identfier
ORA- 06512 at datamove.datamove, line 146
ORA-06512 at line 49, which is the line for
the TestWHERE string.
so in the procedure, if DBMS_OUTPUT is correct, the execute immediate is operating on the where clause and it
thinks the JAN field is incorrect. I have put single quotes around it as well ...

Sqlcode and sql%rowcount as test conditions

I am translating a procedure from Ingres to oracle. I use the Oracle sqlcode and sql%rowcount
variables in place of Ingres's iierrornumber and iirowcount.
I replaced the ingres names with the oracle names, and now am wondering how how oracle uses these
values.
I am using DBMS_OUTPUT.PUT_LINE to display the contents of sqlcode and sql%rowcount.
What happens when I get "no rows selected". I run the same query in standalone command line
and get no rows selected .. and it's correct because I don't have data that matches).
But when I run it in the procedure, I don't get any values in sqlcode or sql%rowcount ... the
program just exits. The author was using the ingres code to test if there was data there and then
continue to do something else.
If you get no rows returned, does that mean, the sqlcode is 0 ? and the sql%rowcount is emtpy?
which is why my DBMS_OUTPUT.PUT_LINE doesn't display anything ?
my example........
before this section in the procedure ... after running a different select that returns data ...
I am using the DBMS to debug the values I have going in ...
DBMS_OUTPUT.Put_line ('BEFORE sqlcode is' || sqlcode);
DBMS_OUTPUT.Put_line ('BEFORE sqlrowcount is' || sql%rowcount);
Select value from table
where condition ='Y'; > this select will product "no rows return" and ignore the 2 DBMS_OUTPUTS beow ---
DBMS_OUTPUT.Put_line ('AFTER sqlcode is' || sqlcode);
DBMS_OUTPUT.Put_line ('AFTER sqlrowcount is' || sql%rowcount);
When i run the procedure... I get the DBMS BEFORE statements, and nothing afterwards ...
BEFORE sqlcode is 0
BEFORE sqlrowcount is 1 >>>> that is all that displays
Since I am getting the "no rows returned" ... how does oracle handle it to anyone's experience ?
Thank you. I am learning much from your comments and information.

Thanks to your answers .... The procedure is below. I've had to hand type it in, so typos are my mistakes.
The procedure compiles . When there is data to be found, I get the DBSM_OUTPUT lines of code ....
msg_read is Y
sql_error is 0
row_count is 1
p_vol_id is 880091
When I enter in a file name that does not return ANY rows back I will get the msg_read
DBMS_OUTPUT line
msg_read is Y
Call completed.
It doesn't show any 0 for sqlcode or sql%rowcount
The original author used the Ingres return codes as input to process the rest of the code...
It seems like oracle bounces the procedure once there are no rows to be found.
I just added this part ....
having an exception in the clause shows that Oracle is bouncing it to the WHEN OTHERS
exception ...
Any ideas of how to get Oracle not to do this ?
I am trying to keep things simple, and all I am testing for is if I get records back the code does things,
if not, I do something else
create or replace procedure userfile(vms_fil_name IN varchar2, msg_read IN Varchar2)
authid current_user
is
p_vms_file_name varchar2(255);
p_vol_id varchar2(255);
p_orig_id varchar2(255);
p_incoming_message varchar2(255);
sql_error number;
n_count number;
begin
p_vms_fil_nam :=vms_fil_nam;
DBMS_OUTPUT.PUT_LINE ('msg read is '|| msg_read); >> verify incoming parameter
IF (msg_read ='Y')
then
select vol_id,
orig_id,
incoming_message
into p_vol_id,
p_orig_id,
p_incoming_message
from
table one_table a
where
a.vms_fil_nam = p.vms_fil_nam
and incoming_msg ='I';
n_count :='sql%rowcount';
sql_error :='sqlcode;
DBMS_OUTPUT.PUT_LINE ('row count is '|| n_count);
DBMS_OUTPUT.PUT_LINE ('sql_error is '|| sql_error);
DBMS_OUTPUT.PUT_LINE ('p_vol_id is '|| p_vol_id);
end if;
exception >>>> just added this part as the last test....
when others
DBMS_OUTPUT.PUT_LINE ('other condition has been met');
end;
call userfile ('GEORGE','Y');

Migrate from Ingres DB to Oracle

Hi Friends,
I have to migrate from Ingres DB to Oracle and the application developed by Oracle Forms.How can we do this any process of docs.
From my research,I came to know about Transparent gateways,But Oracle will support for this or not I'm not sure.Any such experience shared
will be really useful.
Regards.

We have two more customers that currently are in the process of upgrading from MS SQL but as far as I know no one has actually performed an upgrade this far.
If you want to upgrade to OIM 9.1 you will have to wait until the upgrade scripts are available (estimated arrival H2 2008 according to the latest info I have).
If you would like to discuss this further send me an email on firstname.lastname@my_company.com (you can get the "variables" from my forum profile)
Best regards
