Oracle Pipes and Forte

Does anyone have any experience using the Oracle pipes facility from an Oracle
stored procedure to talk to a Forte Service Object. We believe its possible, but
would like to hear some war stories.
Thanks,

FWIW, as of three days ago we have:
OpenVMS v7.1
Oracle v7.3.2.3.2
Forte v30G2
The local Forte apps are limited and small to date. Testing (including Y2K)
failed to show any problems with Forte and Oracle.
I'd be interested to know about any specific problem you have with Oracle
v73232 and Forte (30G2).

Re: Crystal Reports 5.0 (32-Bit) and Forte 2.0H16 on NT3.51

Dear Silke,
Crystal's default for identifying a table in the report design is
<schema>.<table>. You can change that by going to the Database Location menu
item and cutting the schema prefix off. You should do that for every table in
the report. The PESetNthTableLogOnInfo function will, I believe, not change
the schema prefix of a table, since it assumes you really want that schema,
i.e., as an override. Also, if you are using the propagateAcrossAllTables
feature of the function make sure that every table has the schema prefix cut
off, otherwise those tables will be skipped, since the propagate feature applies
to all other similar tables only. For example, some of the tables could be
Sybase, etc.
I believe you can change the default behaviour of the CR Report Designer in the
File->Preferences menu, so that when reports are designed the schema prefix is
not automatically attached.
I have compiled some guidelines on designing reports to make them work properly
with Forte. I will try to send them to you next week. Crystal Reports and its
C API are a good product, and you will get good performance once the report
design is set up properly.
Yours very sincerely, John Hodgson.

The hotline from Crystal told us, when using subreports you have to use
the PESetNthTableLogOnInfo and to go through all the subreports and
change the connect-string.
Our experience is, you have to do both: change the report and call the
other function for the subreports.
Thank you very much for all the tips.

Hi There,
Crystal reports stores Database name as a hard-coded
value in the
report template. So if you have to use an other
database, you will
have to open the report template and modify the
database name. I
think this is why you are getting Crystal API error.
Hope this helps!

Hello,
I wonder if we have a similar problem.
We are using Crystal Reports 5 and Forte 3.0.F.2. For
the interface
between Forte and Crystal we have in Forte a Lib using
C-wrappering to
the C-API of Crystal.
We have developed a report on a database in our
development-environment. This report comes up with data
and works
correct. It's no different if we have saved the report
in Crystal with
data or without.
If we want to use the same report on another database
in our
test-environment the window from crystal reports comes
up and when
starting there is an error from the Crystal API
function.
Both environments use the same version of an Oracle
Database and are on
Open VMS. The client for the test is in this case
always the same.
From the C-API we use the method PEStartPrintJob after
we have specified
the rest for the report.
Is there a possibility that this is the same error you
mentioned? Or do
you have any other ideas?
Any help is appreciated.

Tim,
You need to upgrade to CrystalReports 6.0. There isa bug in the
interaction between Forte and CrystalReports 5.0 (Idon't know on
which side the bug resides, but I think that it is onthe Crystal end,
since the problem occurs both through C-wrapperingand OLE
interaction), which does not allow you to invoke thePrintReport
method unless you have saved data with the report.
As far as I know, there is no workaround, and theonly solution is to
upgrade to CrystalReports 6.0.
FYI, there is no ActiveX control supplied withCrystalReports 5.0 -
you are actually using standard OLE integration.
Hope this helps...

Hi Forte-User !
We got a big problem here using the crystal active-xcontrol. On my

crystal reports installed completely) all works well.On our test
machine (with only the crystal ActiveX

The cause for shutting down (no stacktrace orsomething like that) is
a generated c++ exception in crystal -

Has anyone made the control work under nt 3.51 ? Doesanybody know

RE: NT Server Reboot and Forte Partitions[Ref:C943460]

Hi Bradley.
At our customers, we need one of our Forte applications to be running for data
communications to take place. After a reboot, we need this application's
partitions to come online. The way we did this (as you suggested) was to use a
BAT file, and then install this as an NT service (we used a utility that comes
with the NT resource kit - srvany).
This works fine for us. One of the issues we had was that the partitions tried
to come online before Oracle was running - this resulted in the dbsessions
failing and the partitions not coming online. We got round this by preceding
starting the partitions with a loop that polled Oracle until it was up. Needless
to say, piping all output to log files was essential for us to figure out what
was going on.
Hope this helps,

I have a system administration question for users with NT servers in
their Forte environment. If I have installed Forte partitions on an NT
server which I would like to startup when the server is rebooted, then
what are my options for scripting this to happen automatically?
Currently the only Forte process on the server which starts up
automatically is the Forte node manager, through the installed NT
service. I have been contemplating setting up a BAT file process as an
NT service which would wait for the Forte node manager service to start,
and then execute an fscript file to start the required forte partitions.
How is this situation being handled in other environments? Thanks.

Hi Brad,
I am not sure if this is the right solution in the long run, but if you
login into NT after reebot you can create a simple client that "pings" your
service objects and put the shortcut into the Startup Group. I think such a
client may also be useful to monitor your Forte server for application
specific parameters, instead of relying only on logs/econsole.

RE: (forte-users) Forte not letting go of Oracle connections+ RE: (fort

The bug was just reported yesterday so they might not have it available to
the public for a while. I am guessing this bug has been around since 3.M.?
and its very easy to verify it if its happening in your environment. Also I
have been talking to other user that are not using Oracle (Sybase instead)
who are also seen the same problem. I think this is a problem across all
database because there is some fundamental event or process that is not
taking place to close database connections. But just to be safe verify it
in your test environment before moving to 3.5. To verify if its happening
in your Forte version just create a small application that connects to the
database and run it in debug mode. Log into the database and then stop the
debug session. The connection will still be open. This will also occur
when you use the running man or in a deployed application.

Problem with implicitly created Oracle pipes

Hi, I am having a problem with implicitly created Oracle pipes. I am not sure if this is the correct forum for this topic, but I could not see one which suited better..
I am using Oracle pipes as a commiunication mechanism between processes (some are written in PL/SQL and other in PRO*C).
The general problem I have is that if a timeout occurs during the communication process, I end up with 1 or perhaps 2 implicitly created pipes.
The biggest problem for me is that I am unable to determine if a create is implicitly created (via dbms_pipe.send_message or receive_message). This causes problems, since these implicitly created pipes are left behind and not deleted. I'll show you the basic flow of the processes and you shall see my problem.
server: create request pipe "req_pipe"
server: listen for request on requests pipe.
client: create two pipes for comms with server.
client: send request and the names of the newly created pipes to the server.
server: read request and pipename from request pipe (from this point all comms between the client and server are now done over the 2 pipes the client created).
server: send ack message to client to ensure they are still there (since requests can be queued in the request pipe and clients could have timed out before the request is received)
client: send "i'm still here" ack back to the server.
server: process request and send result back to client.
client: send ack back to server to let server know we have received the response.
server: send ack back to client to show that work is now committed.
OK thats the general event flow. I use the rule, that pipes created by a process are removed by a process. So the client always removes the pipes it created in all situations. But since this can happen at any point we can get in the situation:
client: timeout occurs, delete pipes.
server: send message to client (creates an implicit pipe) and therefor works (no errors raised)
server: do a read for response from previous message. (implicitly creates pipe) (will fail).
Now we have two implicitly created pipes! These pipes will exist until the database instance is shutdown, and in a poorly performing environment, we could get thousands of these pipes lying around... not a good situation.
How can I either stop pipes being implicilty created, or how do I detect if a pipe was implicitly created.
I have tried a couple of things, like using v$db_pipes to check if a pipe exists before doing send/reveive calls but this is FAR to slow to do a select on that view.
We have also looked at keeping a record of pipes created by the client then have some process (perhaps the server) clean up these pipes after some time frame. This is a workable solution but is not favourable since it adds extra overhead having to check these pipes often, and created an extra level of complexity which is not required..
Any suggestions will be greatly appreciated.
Feel free to email me with any suggestions on my email provided below, or just post a reply to this formum..
Many thanks,

Oracle Pipes- 10g RAC?

Oracle Pipes is not working on 10g RAC?

"not working" is a very broad, sweeping statement to make. For all we know, you simply do not know how to use DBMS_PIPEs. Or maybe your code is simply buggy.
So if you expect a helpful response, you must help us first to understand what problem you are running into. This means at least explaining what you are doing using pipes (sample code will be great), and the actual ORA error messages encountered.

JSDK 1.4 and Forte on Windows 98 - which version?

Hello all,
I am brand spanking new to Java ... so please bear with me. I have just installed the latest and greatest SDK
1.4. I have also acquired a great book on Java programming which contained on the CD , SDK 1.3.1 and FORTE 2.0 Community Edition. I am also running on Windows 98SE.
According to the docs, Forte 2.0 needs an NT machine or WIndows 2000 to run. I also found that the 3.0 version of Forte can run on Windows 98, but I need the
JSDK 1.3.1 (so it says) to run FORTE 3.0.
I am assuming that I can download/install FORTE 3.0
from this site and install with the JSDK 1.4 (hoping for a little backward compatability)........
Does anyone know if this is do-able?????...... I was kind of bummed when I saw that the 2.0 would only work on NT/2000 platforms...
Thanks very much

THanks for the prompt response guys....... I was laid off about 6 weeks ago .... I am an Oracle guy (Developed using Oracle FORMS and REPORTS), but from everything I see and hear it seems that JAVA will be the development tool for Oracle databases.... sooooo, since
I have some "free" time, I've decided to learn JAVA and get my Sun Certification....... lots of work, but I am
quite excited, so if you see my postings and they look kind of weird , it's my learning curve so-to-speak talking,
Sure wish I was in college now as my understanding is that JAVA is one of the required C.S. courses......

Oracle PIPES useability?

production environment? I anticipate volumes of only tens of thousands of messages per day.

I have used them with hundreds of messages per hour, 24 hours a day, without a problem (version 8.1.7 anyway).
You just have to make sure to get them off the pipe eventually since they will queue up and consume memory until removed.

Urgent : Oracle Pipes

We have a system that writes full inserts statements into an Oracle pipe using DBMS_PIPE. Then there is an Oracle job that 'reads' out the pipe and executes the statements using DBMS_SQL. Now what we notice is, when the pipe gets full then everything is slowing down and it is even impossible to call various procedures.
What can I do about it or is this a normal behaviour?

We are using a Ms Transaction server as Transaction coordinator. In our oracle procedures we're also doing logging into tables. Now if Ms Trans. server backroles a transaction we don't want the logging being affected.I'm sorry I don't know what a 'Ms Transaction server' is. So you mean MS, as in Microsoft?
Anyway, to answer your question. I can't - I don't know if full pipes can bring a system to it's knees. If that is the case you could read your statements faster, and store them in an Table, or Advanced Queue. And process them in the background. This way you pipe queue might not get so full, so fast.
You didn't describe how many machines are involved. Does one central machine send DDL requests to other machines? Sounds like a large task, and a lot of work.
It is too bad your MS Transaction server can't just cram your DDL statements directly into a Oracle table, across servers, that could be your log, then you could run the statements from there, keeping a status column of which have been processed.

Oracle, Null and empty Strings

Currently I'm facing problems with a class, which contains a String, which
is set to "" (empty String).
When the class is persistent, oracle writes null to the table column
(which seems to be common oracle behaviour) and when retrieving the class,
the field is set to null as well, giving me a lot of null-pointer
exceptions.
Anyway ... I can cope with that (just a lot of extra work)
far worse is the problem, wenn searching objects, that have this field set
to "" oder null.
Oracle can't find the records because JDO creates Querys "where
string=null" or "where string=''" , where oracle expects "where string is
null" to find the records.
Is there a workaround or solution ?

Yeah, that would work as well, thx, but since I have to cope with
null-Strings now everywhere in my program, it doesn't hurt just to forbid
empty strings on the program side.
In future times I'll test on Oracle first, then porting to DB/2 - this way
I suppose work is far less to garant compability.
Nevertheless ... having to set the bankcode into quotes is a kodo bug in
my opinion.
Kodo knows the type of classfields (in this case string) and shouldn't
send the parameter as a BigDecimal to the database.
Given that, and having only bankcodes of null (only neccesary when using
Oracle), the method would look like:
public Collection getAccounts (String bankCode)
throws Exception
return getAccounts (Account.class, "bankcode=="+bankcode);
which is how a transparent persistent layer, um, should be , um , I mean
... just transparent ;-D

Couldn't you just do something like:
public Collection getAccounts (String bankCode)
throws Exception
String filter;
if (bankCode == null || bankCode.length () == 0)
filter = "(bankCode == null || bankCode == "")";
else
filter = "bankCode == "" + bankCode + """;
return getAccounts (Account.class, filter);
If I understand the problem correctly, this should work for all the
databases.

What operations are you performing to cause this SQL to be issued? You
say you are having trouble removing objects, but this is clearly not a
DELETE statement. Is this the SQL that is issued when looking up
objects by identity?I'm not removing objects, I was removing just quotes from parameters ;-)
A string column... is it also represented as a string field in your class?Yeah ... just to give you an impression of the code:
First we have a class, representing a bank account:
public class Account {
private AccountMgr myAccountMgr;
private String bankCode;
private String id;
Note, that in nearly all cases bankCode will be a number or null.
I have a second class "AccountMgr", which does all of the persistant stuff
(seaching, making persistent etc.)
This class has two methods, one versatile (protected) to retrieve accounts
by a given filterString and one who just returns accounts by bankCode,
building the expected filterstring. Here is my current working version:
public class AccountMgr {
public Collection getAccounts(String bankCode) throws Exception {
if (bankCode!=null) {
if (bankCode.equals("")) {
throw new Exception("check code, bankCode='' not allowed to get
same behavior from DB2 and Oracle");
// if set, quote the bankCode
bankCode="""+bankCode+""";
return getAccounts(Account.class,"bankCode=="+bankCode);
protected Collection getAccounts(Class accountClass, String filterAdd)
throws Exception {
PersistenceManager pm = MyHelper.getPersistenceManager();
String filter="";
if (filterAdd!=null && !filterAdd.trim().equals("")) {
filter+=filterAdd + " && ";
filter += "myAccountMgr==_accMgr";
Query query = pm.newQuery(accountClass, filter);
query.declareParameters("AccountMgr _accMgr");
return (Collection) query.execute(this);
As you can see, in the first method I have to set the bankCode into
quotes, when it's not null.
This is because otherwise a filter like "bankCode=1234" will be translated
in a way, where 1234 is send as a BigDecimal to the database:
[...] executing statement <4239745>: (SELECT [...] FROM JDO_ACCOUNT t0
WHERE t0.BANKCODE = ? : [reused=1;params={(BigDecimal) 1234}]

Select query differences between oracle 9 and oracle 8.

Hi,
I have a problem using the select query between oracle 7 and oracle 9i I don't have the same result :
ex:
With oracle7
SQL> select 'champ1','champ2' from DUAL;
'CHAMP 'CHAMP
champ1 champ2
With Oracle 9
SQL> select 'champ1','champ2' from DUAL;
'CHAMP1' 'CHAMP2'
champ1 champ2
So Can someone tell me how to solve this problem ? Is there a parameter in oracle 9 to set?
Thanx.

Whenever you are posting anything over internet forums like this - you should be very careful about not just posting the details which requires to solve the problem - also should be sensible about your question.
This is not at all desired when you are posting such question. It may be because - you may not well aware of the fact.
My suggestion is -> First Go through the basics Of SQL in general.
Then go for any specific product like Oracle/ SQL Server/ Sybase etc.
And, finally learn the advanced commands of that DB.
You asked it - may be you thought the difference in output in terms of lines. But, that is not your actual output. That is the graphical display part only.
Anyway,
You can get the quite familier output by first type the following command ->

What is the Diffrence between Oracle 11 and 11i

What is the Diffrence between Oracle 11 and Oracle11i ?.
With Rgds
Arun J.Isaac

Oracle 11i is internet based and run with java platform where we can see the applets downloading alongwith oracle forms and it refreshes all the jar files in oracle default directory.
Oracle 11 is not intergrated with Java its an Oracle standalone platform.

Oracle Forms and Reports Installation - Creating domain failed

I installed the weblogic 10.3.6 (Oracle WebLogic Server 11gR1 (10.3.6) + Coherence + OEPE - Package Installer) in my Microsoft Windows(32-bit JVM) system first.
But there was an error occorred when the package of forms and reports (Oracle Forms and Reports 11gR2 (11.1.2.2.0)) was installing.
Please find the following error message for your reference.

hi user ...
on windows there are some steps in front of installation and configuration.
1) cleare the Windows Env (Path .. Programme x86 )
no Blank in Path and so on
2) insert into your local host file your server and IP Adress
3) in Windows 32 setup of WLS is JDK included so you don't have to install the jdk in front of WLS
4) verify if you are using the right installation medium (jdk 32 bit, wls 32 bit , fmw 32 bit
in your OraInventory/logs directory is a *.out file for your installation please can you put this file in the forum
is there a nodemanager up and running (if so please stop)

We're trying to integrate Discoverer with Portal unsuccessfully.
We made many things in accordance with oracle's documentation until add discoverer portlets (worksheet and list of workbooks) in a test page.
In view mode, the worksheet portlet shows the error:
"The portlet has not been defined. The publisher must define the portlet by clicking on Edit Defaults for the portlet on the edit mode of this page. Please contact the publisher of this page."
We think we have to edit properties before. Is this? Anyway edit worksheet portlet crashes between step 1 and 2. The error is: "The listener returned the following Message: 500 Internal Server Error".
We have a public conection created in EM and a discoverer application which can be viewed using plus or viewer.

Hi there,
Have you applied any patches to 9ias since it was first installed? We had the same problem and had to apply a couple of patches to get the portlets working.
1. Apply the 9.0.2.53.16 one-off patch for Oracle 9iAS Discoverer which takes Discoverer up to 9.0.2.53.16. This patch appears to be password protected and you need to get someone at Oracle support to give you a password.
2. Apply the Discoverer Portlet Provider: 9.0.2.53.00c patch (patch no. 2595444) which gives you a new discportal.xsl file that actually works. It's this second step that solves your problem but you need to do step 1 before this. This is password protected as well.
3. As you've upgraded Disco on the server to 9.0.2.53, you'll need to upgrade Disco Admin & Desktop within your 9iDS installation using patch no. 2555265. This is because Disco 9.0.2.53 uses an upgraded EUL that Disco Admin & Desktop need to be patched to use.
This was the course of action Oracle support advised us about nine months ago. Of course they may have released a further patch to Disco that does 1 & 2 in one go, but we regularly carry out steps 1 and 2 on servers we use and we can use the Disco portlets successfully.
Hope this helps
