Controlling packet size from 32K to 4K for SQL DSN
I've been engaged by my SQL administrator to find out how the packet size can be reduced from 32K to 4K in the CF9 Enterprise environment in a multi-server configuration. Although it's not likely related to the version rather than the JDBC Drivers provided in the product, none the less there is no clear way of identifying where this could be changed within the ColdFusion DSN's. Does anybody have any insight on how to control the packet sizes in a SQL DSN i Coldfusion 9 or 9.0.1? Would be greatly appreciated.
If you are using MSSQL, open the CF administrator, goto the datasource, click the "Advanced Settings" button and enter in:
packetSize=8
within the Connection String textarea box then hit submit, there should be no need to restart anything
Connection details for the PacketSize property:
Valid Values
-1 | 0 | x
where x is an integer from 1 to 128 that represents a number of bytes.
If set to -1, the driver uses the maximum packet size that the database server accepts.
If set to 0, the driver uses the default packet size configured on the database server.
If set to x, the driver uses a packet size that is calculated using the specified value multiplied by 512.
Example
If PacketSize=8, the packet size is set to 8 * 512 bytes (4096 bytes).
Default
-1
Data Type
int
Microsoft recommends (4096 bytes)

Where do we control packet sizes in IDoc's processing.
Hi
Can you please let me know
1) how we can control the Packet Size while processing Idoc's?
2) How to find out how many Idoc's got / can be processed in one packet?
3) Where can these Packet size settings be made?
Satish.Hi,
You can get control on indoc inbound processing only if the processing is "triggered by background program" in the partner profile.
>1) how we can control the Packet Size while processing Idoc's?
It is controlled in the variant of the RBDAPP01 program
>2) How to find out how many Idoc's got / can be processed in one packet?
This is tuning : you have to experiment to find out the best setup for your specific need.
It is not an easy task because it is not usually very easy to import a lot of idocs in a testbed system.
You have to find a compromise between speed (throughput) and resource consumption.
>3) Where can these Packet size settings be made?
Again in RBDAPP01 variant.

Network Packet Size Or Bandwidth Restriction in Database Mirroring
Hi Everyone,
I tried finding online but couldn't get answer to the below question.
Is it possible to restrict the packet size for the SQL Database Mirroring? Is it possible to tell database mirroring what size packets it should send to the mirrored database? Is it possible to define the bandwidth or packets per second for mirroring? If
yes, is it possible at the server level or database level? If yes, how to do this?
The reason that I want to know this is because, if I have N number of databases on a server and I'm mirroring them on other server in a separate location, how will I get to know the bandwidth constraint and if there is a bandwidth constraint can I control
the data sent through database mirroring to ensure that the bandwidth is not affected?
Thanks
Mayur KashikarDatabase Mirroring has no such setting specific to "per database" or "per server" which can limit the packets sent over the wire. Remember that communication of database doesn't happen via regular port. There is a separate port use by
database mirroring (generally 5022)
Network packet size is setting which is for communication happening on regular connection port (i.e. TDS packets). Database mirroring doesn't use TDS packets but it uses the Service Broker network stack.
In short, there is no such setting which can control the communication the way you want.
If you search for Jumbo Frame, you might get some reference about performance gain but remember that if you use Jumbo frame then it has to be supported by each and every component in the network else you would have packet drop and mirroring would be
disconnected.

How do I change packet size for a single load
All,
I need to change the packet size for a single load I'm doing. How do I set that?
Thanks.
DaveHi..........
For this u hav to go to the infopackage scheduler........
If u r in Process chain >> Right click on the infopackage >> Maintain variant..........then it will come to the IP scheduler..................In the Top Scheduler Tab >> Click on it and select DataS. Default data transfer .......Now there may be a delta IP and Full upload IP for the same datasource.......check ur IP .....it is full or delta..........if full change the packet size for full upload..............otherwise for delta upload........
If the IP is not a part of any Process chain..........then go to RSA1 >> Find the IP..........and double click on it........then the IP scheduler screen will open..........
You can make global settings for all datasources...... in the transaction SBIW in the area General Settings >> Maintain control Parameter for Data transfer......... The parameters that you maintain here are valid as global standard values, and thus apply to all DataSources.
Hope this helps.....

Debjani........

Configuring Packet size for IDOCS on outbound Side
Folks,
Can we configure the packet size for idocs on the onutbound side of the Adapter ?
ManishHi Manish,
It is posible if all 1000 idocs are of same Idoc type.
Jus go and change the occurene of Idoc in the XSD as 1..Unbounded. SO that your the message can hold multiple Idocs.
But let me clarify here, if you send 1000 idocs from R3 , it will come to XI as one-by-one. There is no mechanism to get 1000 idocs at a time. So you need to collec all the idocs and then send it.
Just have quick look into this

Looking for app that will allow me to control my iphone from my desktop
Looking for app that will allow me to control my iphone from my desktop. I would like to be able to send text messages, etc from my computer instead of using my iphone. I don't want to jailbreak my phone. Does anyone know of app like this?
Thank you,
ScottWindows or Mac? You can at least send iMessages from a Mac with Mountain Lion installed.
There are apps that let you do the reverse (control the computer from the phone). I don't know of any that let you go the other way. It would be kind of cool if we could do this though. But, I suppose it could open up a Pandora's box of security problems for the phone itself. Just imagine somebody hacking into your phone remotely and using it without your permission.... -
Is there any limitaion for JDBC packet size?
Hi there,
my question is if JDBC like ODBC have the 4k
packet size? If so, is there a way to increase it and if so, what will be the maximum acceptable size for it?
Thanks a lot.
nullOracle supports JDBC at least as far back as 8.1.something; the Oracle JDBC driver is built on a private protocol that existed in at least 8.0, so I'd expect all 8x versions to support JDBC, more or less.

However, you may want to consider using a newer version of the Oracle database; you can download the latest, and a single-user-for-development-only license is free.

SDU size of 32K for streams?
Oracle 11.0.1.7
Oracle suggest that for Streams over WAN set the SDU size to 32K. Does it mean that even the switch,routers and MTU need to be 32K? I am not sure if switch or router support that size. If not then what should MTU be?
http://www.oracle.com/technology/products/dataint/pdf/twp_streams_performance_11gr1.pdfI am not aware of anywhere in the HA docs where Oracle correlates the two. You should look in the Metalink knowledgebase and discuss this with your network admin.

The setting for packet size (RSCUSTV6)
HI Guys
i want to know the setting for packet size (RSCUSTV6). can i do in production . or dev.
i want change as
Packet size = 20000
FrequencyStatus-Idoc = 5
please advise on this.
Regards
sivaHi Patel,
This will impact all the loads in the system as this wil change the parameters for all the loads.. And hence its always recommended to reduce the data packet size at the Infopackage level...
Also u can do the settings for the ODS Activation process as well using this RSCUSTV6 t-code.
Better chane it for the specific job.
thanks -
Hi
i have two questions
1) where can i set the data packet size in BW and R3 and also in BI how and where can we set .
2)by what method/logic we will select the key fields in dso.
ex: i have 5 tables in the sourse and each table will have primary keys, now how do we know that particular primary keys should be kept in KEY FIELDS folder in DSO.
full points will be assigned.HI,
Data package settings for the data to be extracted from R3 to BI can be done through :
1) SBIW>General Settings> Maintain Control Parameters for Data Transfer
These settings are common for all the info packages which extract data from R3.
2) If u want to do settings relevent to specific Infopackage then :
RSA1>Click On the Specific Infopackage>Scheduler(in the Menu Bar)-->DataS Default Data Transfer.
3) And if you want to do DSO Package settings then:
Got to Transaction RSODSO_SETTINGS
Here u can do package settings for DSO activation ,paramenter for SID generation ect.
And selection of Key fileds depends upon the requirement.
Based on the key fields what all the data fileds u want to overwrite or add the corespomding data fields

Voice control signaling traffic from a Cisco phone
Silly question I guess but here it goes. What is the purpose for having the RTP and control signaling traffic marked with different markings and then placing the traffic into different queues? What not treat all traffic coming from the phone the same? Help me understand the reason I would place the different traffic types into the separate queues. Thank you for your help in advance. P.S. is there any document that explains why this is done?
Well , the RTP(Voice) traffic is much, much more susceptible to jitter and other hiccups that are a minor concern to data protocols. The Idea in j=using seperate queues is to allow the RTP traffic alone to get the pq - this allows the queue to flow smoothly with consistant packet sizes and a constant data stream. The signaling traffic is kept seperate because it really does not need to be in the pq and if it were there it would cause inconsistancies in the types and sizes of packets going through the queue.
http://cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature_guide09186a0080087afb.html
Basically just trying to avoid anything that might cause congestion for the RTP stream
Hope this helps -
BW experts,
I need data packages from SAP 4.7 to get 50000 rows at one in a single packet. Right now in BW it is set to get 20000 max per packet. Where can I change it to get more per packet. I am not able to do it on BW side as it say the maximum source system will allow is 20000, where in the source system (SAP 4.7) can I make this change?
Thanks

Configuring ROIDOCPRMS table
Transaction SBIW
General Settings->Maintain Control Parameters for Data Transfer
Refer OSS Note : 417307
About ROIDOCPRMS
It is an IDOC parameter source system. This table contains the details of the data transfer like the source system of the data, data packet size, maximum number of lines in a data packet, etc. The data packet size can be changed through the control parameters option on SBIW i.e., the contents of this table can be changed.

When my project launches from the LMS, the lauch window is smaller that the actual project size and requires the user to resize the window to see the whole project. My LMS administrator tells me that the launch window size is not controlled by the LMS so I am trying to figure out how I can set this to match the project dimensions.
The size of the browser window CAN be controlled by the LMS, but some LMSs are hopeless in this area and don't provide the settings to do so.
Moodle for example allows you to specify that the course content will open in a new window each time an item in the LMS TOC is clicked and what the height and width of that window will be. However, all versions of SumTotal before the latest one did not give you this option (and that despite the exhorbitant price difference between these two products.)
So your LMS admin might be correct in that HIS particular LMS cannot control the size of the launch window, but that's not because no LMS can do this.
