Performance on Sybase Gateway

Our case is when a row update on Oracle server. A trigger will fire and update a row on Sybase using gateway.
We do a test, for first 1000 records, the speed is acceptable, but when over 1000, the speed drop and need 1 min to complete update one record.
What happen on the gateway and any hint to improve the performance
Thanks
Louis

Louis:
Do you wanna do real-time replicate? I'm working on the similar issues, and my environment is DB2 ==> Oracle.
Have you figure out your performance problem? What's your transaction activity like in your Oracle? As for mine, it is not that heavy--less than 10/Second.
good luck!

Sybase gateway, dropped connection after 700 transactions

Has anyone had a problen with the gateway to syabse. Mine works fine untill I process about 700 transactions then it core dumps. If I have fewer transactions it works fine. Any ideas would be great.

kgronau,
Does it also apply to HS_FDS_TRANSACTION_MODEL=READ_ONLY_AUTOCOMMIT ?
I mean:
a) is the distributed transaction started even with a simple select statement?
b) is it automatically commited, so that I don't have to issue commit?
c) is the commit statement executed only on Sybase side, or also on Oracle?
d) assuming the Sybase account has read-only access (only select granted), is it possible
to configure it in a way that it doesn't need the HS_TRANSACTION_LOG table
for transaction coordination?
I'm very interested in d), because currently my alert.log is full of messages like:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Oracle][ODBC Sybase Wire Protocol driver][SQL Server]"reader"."HS_TRANSACTION_LOG" not found. Specify owner.objectname or use sp_help to
check whether the object exists (sp_help may produce lots of output).
and there is no way that I could create any table on Sybase or get read/write access to it
because of security limitations...
I'm using 11.2.0.1 on Linux.

Performance testing of gateway of GPS enabled phone

Hi All,
We have a GPS enabled phone which uses Apache/Tomcat as the gateway server. We want to do Stress/Load testing on this gateway server for say 500,1000....users. This web server (Apache/Tomcat) is the phone gateway that allows coomunication from & to the phone. This server typically handles communication with the phone like GET POSITION, SEND MESSAGE, SHUT DOWN....
We are told to use the Motorola iDEN Emulator for i730 to emulate a phone. We have the GPS position information for the tests in a txt file.
(1) Has any one in the forum done this type of testing? If yes can you please send me ur e-mail ID so that I can discuss things out.
(2) Does the above mentioned emulator have the capability like we feed the GPS position of say different users & the emulator can transmit the data to the Gateway server or Will we have to write some piece of code to make this happen?
(3) Can anyone let me know of any load testing tool that can be used in this scenario?
Anyone willing to get in touch with me directly can send a direct e-mail to me at [email protected]
An urgent reply from all you techies will be appreciated.
Warm Regards,
Afroz

Gateway for Sybase or MS SQL - support for Timestamp

Hi All,
Is there any way to get Timestamp data out of Sybase or MS SQL Server?
I thought this would be pretty straightforward, but after a short investigation I'm no longer that optimistic...
The "Database Gateway for Sybase User's Guide" says in Appendix A, that the following conversions are performed by the gateway:
(Sybase - Oracle)
DATE - DATE
DATETIME - DATE
SMALLDATETIME - DATE
TIMESTAMP - RAW
TIME - CHAR(15)
It says the same for MS SQL Server.
What I need is a conversion from Sybase DATETIME into Oracle TIMESTAMP, but I'm guessing there is a limitation of the Gateway
and it is not able to use the millisecond data in any way... Am I right?
Or maybe there is some magic setting in the .ini file for this? Things like HS_NLS_TIMESTAMP_FORMAT seem to be unsupported by Sybase gateway.
I'm using 11.2.0.1 on Linux.
Thanks for any hints.

Hi,
As you have seen in the documentation the Sybase and SQL*Server datatime columns are translated as Oracle DATE datatypes, so the milisecond data will be lost.
the 11.2 DG4MSQL Users Guide actually says -
SQL*Server Oracle Comment
DATETIME DATE Fractional parts of a second are truncated
although the Dg4Sybase Users Guide has the same conversion it does not have the comment.
The only way round it would be use a different non-Oracle datatyp from which you could extract the millesecond part of the string.
Regards,
Mike

Transparent gateway to Sybase: connection error

I have been trying with little success to set up a transparent gateway to a sybase server.
The gateway is an NT 4 workstation, with an oracle server 8.1.7 installed. The sybase server is an ASE 12.0 on a Solaris 8 box.
Are these versions of the products supported? In the gateway documentation only Sybase 11 is mentioned...
Moreover all the examples/schemas given refer to an installation of the gateway on the same machine as the sybase server, whereas in my case the gateway is installed on a separate machine (but it is also stated that this configuration is allowed, provided a sybase client is installed togheter with the gateway).
From what I can make of the error messages / trace files, the problem lies in the gateway not finding the sybase server. But from the sybase client installed on the gateway machine I can connect to the same remote sybase server without hassles, so the sybase client is configured correctly.
Thanks for help,

Gaetano,
The supported products that we list in the manual is only what we have tested at print time. However we update our certification matrix regularly.
Please refer to the certification matrix on Technet.com ( http://otn.oracle.com/products/gateways/pdf/certmatrix2.pdf) for the latest certified configurations.
It looks like you have installed the gateway in the same Oracle home as the database. With v8.1.6 of the gateway this is not possible. With v9.x onwards this is possible.
You can either reinstall the gateway in another Oracle home or upgrade to v9.x.
I recommend that you upgrade to v9.x, since v8.x will be desupported shortly.
As of v9.x the Sybase gateway is located on the database CD and you can install it by doing a custom install.

BPM Parallel Process with Exclusive Gateway

Hi,
I am facing issue with Exclusive Gateway in Parallel Process.
Issu is, process always in In-Progress state at parallel Join. I mean process stops at Parallel Join and more over there are no errors in the process. If I delete Exclusive Gateway in Parallel process, the process is going to next level human task through Parallel Join. It means working fine.
I have designed my process in such a way that, 1st task is Human Task ---> then Parallel Split with 2 Human tasks, out of one task performing throught Excusive Gateway and another one is just simple approval. Finally I am merging these two Human tasks using Parallel Join then finally triggerting Approval Human task, and closing the Process.
Appreciate your quick suggestions to fix this issue.
Thanks in advance,
Dev...

Hi Unni,
Thanks for your reply.
I have checked all the parallel tasks and all are in completed state. No errors.
If I delete Exclusive Gateway it is working fine. I have checked step by step tasks in NWA, and every thing goes well.
Please let me know If I missout anything.
Thanks in advance,
Dev

XML Gateway Mapping Issue

Hi All,
My map has following structure
-<envelope> -- root element and also level
-<gdsnItemRegistryResponse> --Level
-<docException> --Level
-<docAcknowledgement> --Level
<docException> and <docAcknowledgement> are siblings
I dont have any dtd's associated with map
In payload <docException> and <docAcknowledgement> can be occur in any order
When I push the payload with following order same as defined in XMG map
-<docException>
-<docAcknowledgement>
its working fine
but when I push the payload with different order
-<docAcknowledgement>
-<docException>
PL/SQL procedure calling on INPROCESS action on <docAcknowledgement> is
working fine,
but
PL/SQL procedure calling on INPROCESS action on <docException> is being
performed, but XML Gateway is not passing values to the parameters of that
procedure.
When I verified the parameter values in log, all are null
I am calling same procedure on both tags
How to overcome above problem ?
How to enforce that two tags can be in any order without dtd?
Thanks
-Praveen

Just I am confirming my map structure
-<envelope> -- root element and also level
----<gdsnItemRegistryResponse> --Level
-------<docException> --Level
-------<docAcknowledgement> --Level

Calling a sql server sproc and function from oracle gateway

Hello ,
i am new to oracle gateway,
we are trying to call a sql server 2008 stored procedure and function which return result set like a table result set.
Can you please share some syntax of how to do it.
and capture the data set and loop through or output it.
Thanks
madhu

On My Oracle Support you find some notes how to do that. The first one is
Different Methods For Calling MS SQL Server Procedures Using DG4MSQL (Doc ID 197192.1)
and a note using result sets (it was written fir the Sybase gateway but works the same way for DG4MSQL) is:
How to Call a Remote Sybase Procedure Using DG4SYBS (Doc ID 351400.1)

Why Sybase is not the prefered database for SAP?

Dear Sir/Madam,
Why Sybase is not the preferred database for SAP?
What is the difference between Oracle performance and Sybase!
I am sure that both are RDBMS!
Please Clear this doubt.
Sreevidya.S

Because Sybase is a much smaller "player" in the DB world.
Oracle is the industry leader; and it is usually a wise decision for a software product to store it's data into the "best of brand" technology.

Experiences migrating from Sybase to Oracle

Hi all,
I have been asked to look into migrating a database from Sybase to Oracle.
I know there is lots of info on Oracle's website, which I have downloaded, but I was just hoping for some info about some of your experiences regarding your processes. What are the gotchas. I suspect there will be a few.
Anything that will help would be of interest.
Many thanks
VicC

HI VicC,
I work within the SQL Developer team and not a customer as such, but the follow maybe of use.
SQL Developer is a migration aid, its not 100% magic bullet.
SQL Developer does alot of the manual conversion for you quickly. But you may find Testing / Tuning and the application migration (if any) take you the most amount of time.
SQL Developer aims to migrate you tables, indexes, and data without issue. But SQL Objects like Procedures, Triggers, Views and Functions conversion will likely require manual work on top of the automatic conversion provided by SQL Developer.
SQL Developer does not yet automatically handle things like the tablespaces structure or the the logins. Although these things can be scripted and managed more easily within SQL Developer.
I would recommend downloading and performing the migration from a non production instance ASAP.
SQL Developer can perform a migration quickly and you will then be able to assess what SQL Developer can and cant do for you.
I would recommend creating a migration repository on an Oracle database local (install Oracle XE if you dont have a local database) to the SQL Developer instance you are using.
I would also recommend downloading SQL Developer 2.1
Here are some key sites regarding Sybase migrations.
http://www.oracle.com/technology/tech/migration/workbench/viewlets/sqlserver.html . This viewlet for SQL Server is the same process for Sybase.
http://www.oracle.com/technology/obe/hol08/sqldev_migration/sybase/migrate_sybase_otn.htm . This Oracle By Example takes you step by step through a Sybase migration including some gotchas
http://dermotoneill.blogspot.com/2008/06/sql-developer-migration-workbench-151_11.html . This is my blog outlining the steps to perform a Sybase migration.

Performance benchmarks?

Hello,
Has anyone done any performance benchmarking on Portal Server? (Or know
where I can find such information?)
I'm curious to know:
1. Given iPlanet's recommended hardware, how many concurrent users does
this support with decent performance (SSL to gateway to non-SSL server)?
2. How does the product scale...e.g. if I wanted to have 250 concurrent
gateway users (running SSL), what hardware is recommended? 500 users?
1000 users?
3. Has anyone tried (or does the product even support) the use of SSL
accelerator cards on the gateway machine?
Any help is appreciated.
Thanks,
Murray

Hi.
We did some benchmarking in january, at the SUN iforce center in holland,
using iPlanet Portal Server SP2 Hotpatch3.
We focused on measuring:
1) Average time to log in to portal(with default channels, netlet set up) as
a function of simultaneous users
2) Average time to do a "standard operation" inside portal.
Our results supported the numbers from iPlanet saying thath one could have
250 simultaneous "secure" users pr CPU in this setup. (SP2 HP3)
This "guaranteed" number of simultaneous users pr CPU for iPS 3 SP3 is said
to be increased to 1500.
We used SUN E 220 s with 2x450 MHZ CPUs and 1 G RAM.
The performance increased remarkable when we went from gateway and server on
1 machine, to separate gateway and server.

Reducing the memory footprint of Sybase ASE

Hello All,
We are doing a test install of SAP Solution Manager 7.01 on Sybase ASE 15.7.
Since this is just a test setup, we started off with a lower-than-recommended hardware configuration (4 GB RAM only) due to time constraints.
While post install performance of SolMan was decent, performance during solman_setup (setting up technical monitoring) has become appalling. We are not able to complete the configuration process at all as the SolMan configuration web application has become very unpredictable and extremely slow.
The SolMan install is centralized and on a windows 2008 box. Windows task manager shows consistent memory usage of up to 90 - 95%. We also tried reducing the total number of work processes to just 8 but that did not help much. We see in 'task manager > resource monitor' that sqlserver.exe process is committing close to 2 GB of RAM when in fact it seems to be using much lesser when seen directly in 'task manager > process tab'. Please tell us about any memory optimization we can perform for Sybase ASE in order to complete out Solman_setup. We were hoping that we could change the 'max memory'/'total logical memory' setting for the DB directly using DBACOCKPIT tcode but could not do so as the parameters seems to be read-only. We could not find much documentation regarding memory optimization for the DB. Please help out. Thanks!
-Regards,
Arvind

FWIW ... ASE's 'max memory' setting can be changed on the fly, while 'total logical memory' is a calculated value that you cannot change (ie, it's 'read only'; changing 'max memory' will cause 'total logical memory' to change automatically). [NOTE: DBACOCKPIT is a SAP-provided application that sits on top of ASE; while I know what's doable when connected directly to ASE I do not know if DBACOCKPIT has disabled the ability to change some configuration settings like 'max memory'.]
As for the SolMan performance issues ... I'd recommend reposting your issue in the SAP Applications on ASE discussion group where you're likely to get the attention of more folks with SAP application (on ASE) experience. (While someone may jump in here with SolMan suggestions, SolMan is a SAP application and this group isn't really geared towards SAP applications.)

Installation of Sybase GW in a separate home - 11gR1 on SUN SOLARIS 64bit

Hi all
I have a new installation of 11.1.0.6 database & listener (port 1521) patched to 11.1.0.7 with the most recent patchset and PSU.
Now I need to install Gateways 11.1.0.6 in a separate home. I have jotted down the following:
1. Install Sybase Gateway under new GW_ORACLE_HOME
2. Create new Gateway Listener (new port 1522) using netca from GW_ORACLE_HOME
3. Make modification to listener.ora under GW_ORACLE_HOME
4. Restart Gateway Listener
5. Configure Oracle Database for Gateway Access by creating tnsnames.ora entry under ORACLE_HOME
6. Create database link
question A) Am I missing any steps or is this all I need to do?
question B) Do I need to run the 11.1.0.7 patchset on GW_ORACLE_HOME as well?

you need to modify a gateway init file pointing to the Sybase database you want to access. OUI only configures the connect info - if you need other settings you need to add them.
Regarding the 11.1.0.7 patchset - I strongly recommend to apply the latest patchset as it contains fixes for many known issues.

DB to XML mapping in DB Adapters

Hi,
I am evaluating DB Adapters. My Requirement is to get table rows as XML on which update/delete operations are being performed. XML gateway has a mechanism called db to xml mapping and an api is provided to retrieve the table row as xml by providing the transformation map code and primary key. Is there any such mechanism in DB adapters as well ? All i need is the xml representation of the table row after performing custom transformations. This capturing of xml should happen before any changes are commited to database (as i am intrested in capturing old .
