Setup optimization - Changeover time queries

We are planning to use Setup Matrix based optimization in PPDS to schedule planned orders. Setup group and keys are maintained in routings and available in PDS. The setup matrix is maintained and updated in resources. In the optimizer run, system will read the changeover time (transition time) from the setup matrix. I have queries on this process:
Q1 - Will the change over time also be taken into account while calculating the actual planned order start time and end time? Or will the setup activity time will just be taken from PDS (which in turn comes from ECC routing?)
Q2 u2013 If the answer to above is a no, does it mean that for production execution, APO will provide only the correct order sequence and approximate order start and finish timings? (This would be somewhat a letdown if we can't get a feasible schedule with order start and end timings; something the production folks could aspire to.)
Q3 u2013 We also plan to allow out some manual adjustments in DS Planning Board. When we move the orders around by drag and drop, will the DS Board read the changeover time from the setup matrix?

1. If you have checked sequence dependent set up activity in PDS during planned order creation also time will be taken from matrix not from routing.
2. Change in order sequence in DS board manually will result into different set up times based on matrix defined.

I am trying to setup my new time capsule but it is not working. after entering the airport utility and locating the TC, after I tell the program to continue, the unit just disappear and the setup menu says there is an error. Any idea of what is happening?

I am trying to setup my new time capsule but it is not working. after entering the airport utility and locating the TC, after I tell the program to continue, the unit just disappear from the menu and the setup menu says there is an error. I tried using the wireless connection, and also the cable, but none worked. Any idea of what could be happening?

What are you setting it up as.. join wireless network .. the very worst setup, it will disappear.. reboot the whole network in order modem. router TC.. clients and it will likely reappear.
Tell us what network setup you are using..
If you setup with cable to a computer completely isolated from the network with TC also isolated.. finish the setup of everything you want. .before update.. then plug it into the network. .then restart everything in correct order.. it will work most of the time.

My new Canon Pixma 7250 wireless printer can no longer find my wireless network. My MAC is, Yosemite 10.10.2. I've run diagnostics and Canon LAN printer setup routine many time. Is there a solution? Can anyone help?

My new Canon Pixma 7250 wireless printercan no longer find my wireless network. (It worked fine until recently) I have a Yosemite 10.10.2. I've run diagnostics and the Canon LAN printer setup routine many times. Is there a solution? Can anyone help?

Turn of the MG and unplug the power cord. Leave it off for about a minute and then reconnect the power cord and turn the power back on. Wait while the device attempts to reconnect to your wireless network - the blue wifi symbol on the MG will flash and then stay on once it has connected. If it keeps flashing then you will have to reconnect the MG to your wireless access point via the control panel on the MG.

Most of the time queries remain in suspended state in our production environment.

Not getting any solution.

Wait typeS : PAGEIOLATCH_SH,PAGELATCH_EX is when requested page is in buffer and some other process/request
is holding the lock in buffer.
SQL will manage it internally , Have you faced in performance issue if yes the need to check
1) Fragmentation of indexes. if fragmented the defrag it so that time of execution will less and will also reduce wait time.
2) Any missing indexes is there then create it
3) Update statistics status of tables.
4) Check if any table scan is there the create appropriate indexes on that...etc ....

Scheduling changeover times in non working times

PP/DS heuristics and or the PP/DS optimiser will not automatically place changeover times in non working times, however other smaller APS systems have such functionality. Has anyone come across this or have a method to use to get APO to do this? May be it should be a new development?

Hi Thomas,
Thanks for your reply. Yes i am aware of this setting - this is the standard approach, however do you know of a way automatically (heuristic or optimiser) schedule the set up segment of an order into non working times whilst keeping the produce section in productive time? I know you can amend the strategy and use that in the heuristic but it will schedule all parts of the order in the non working time if it can.
Thanks

How to setup java run time before setting up portal

Dear Experts,
To implement a portal, i need to setup java run time environment to our server. Please show me a way on how to do this.
Thanks
SP

You need to download the Java SDK for your apropriate operating system and install it as per the instructions from the provider. So, for example, with Windows you go to the Sun web site, download SDK 1..4 and then run the setup script.

Optimal Setup for New Time Capsule with Wireless AC

I'm curious to see what the hypotehtical optimal setup for my Time Capsule. I understand that wireless speeds depend on a ton of factors and that part of getting the best connection is just trying different options. I have a new Time Capsule that's connected to the following devices: iPhone 5S; new MacBook Air with wireless AC; old iMac from 2007; old AirPort Express that only supports b/g and a newish Apple TV that supports wireless N, I believe. I was connecting to the network (which was not designated with the 5ghz) and I recently chose the option to label the 5ghz. I'm using that now to stream music with the new iPhone and the Apple TV with no problems, but I have no longer have the option of using the old Airport express because it's an old one. I'm thinking of just getting a new Airport Express and leaving it at that, but wanted to know if anyone has some thoughts on this. I'm sure there's a more concise and direct way to ask this question, but my knowledge is pretty limited here. Thanks in advance.

The Time Capsule is already set up for optimal performance when you open up the box.
You can assign a separate name to the 5 GHz network and point devices that are capable to that network. This works well if the device is located close to the Time Capsule.
But, 5 GHz signals are much weaker than 2.4 GHz signals, so once you move a room or two away, or the signal has to pass through several walls, the 2.4 GHz will be stronger.....and probably faster as well.
But...your device will try to stay locked on the 5 GHz network since you set it up that way.
This type of setup may or may not work best for you. For most users, it is simpler and more effective to use the default settings on the Time Capsule to have both bands use the same network name.
Then, your wireless devices will automatically connect to the signal with the best quality. Best quality may not be the fastest signal since there are lot of factors involved with signal quality. But, if you think about it a bit more, don't you want to have your wireless device connect to the signal with the best quality?
Some users swear by assigning a separate name to the 5 GHz band. I'm not one of them, but If it works well for them and they are happy, then there is no reason to change.
An older AirPort on your network is going to drag down the speeds. You need the new AirPort Express, or better yet an AirPort Extreme if you want to be able to extend the new 802.11ac signal.

SQL Tuning and OPTIMIZER - Execution Time with " AND col .."

Hi all,
I get a question about SQL Tuning and OPTIMIZER.
There are three samples with EXPLAIN PLAN and execution time.
This "tw_pkg.getMaxAktion" is a PLSQL Package.
1.) Execution Time : 0.25 Second
2.) Execution Time : 0.59 Second
3.) Execution Time : 1.11 Second
The only difference is some additional "AND col <> .."
Why is this execution time growing so strong?
Many Thanks,
Thomas

Hi,
this is likely because SQL Developer fetches and displays only limited number of rows from query results.
This number is a parameter called 'sql array fetch size', you can find it in SQL Developer preferences under Tools/Preferences/Database/Advanced tab, and it's default value is 50 rows.
Query scans a table from the beginning and continue scanning until first 50 rows are selected.
If query conditions are more selective, then more table rows (or index entries) must be scanned to fetch first 50 results and execution time grows.
This effect is usually unnoticeable when query uses simple and fast built-in comparison operators (like = <> etc) or oracle built-in functions, but your query uses a PL/SQL function that is much more slower than built-in functions/operators.
Try to change this parameter to 1000 and most likely you will see that execution time of all 3 queries will be similar.
Look at this simple test to figure out how it works:
CREATE TABLE studie AS
SELECT row_number() OVER (ORDER BY object_id) studie_id, o.*
FROM (
SELECT * FROM all_objects
CROSS JOIN
(SELECT 1 FROM dual CONNECT BY LEVEL <= 100)
) o;
CREATE INDEX studie_ix ON studie(object_name, studie_id);
ANALYZE TABLE studie COMPUTE STATISTICS;
CREATE OR REPLACE FUNCTION very_slow_function(action IN NUMBER)
RETURN NUMBER
IS
BEGIN
RETURN action;
END;

CM21 Strategy Profile with Setup Optimization but consider the requirements

Dear guru.
A question about strategy profile in CM21
The system Is able to execute an automatic dispatch that optimize the setup time of the production order but also consider the requirements date in order that the production orders dispatched can cover the requirements without delay ?
Thanks In advance

Dear ,
The system Is able to execute an automatic dispatch that optimize the setup time of the production order but also consider the requirements date in order that the production orders dispatched can cover the requirements without delay ?
To answer to your query I would rather say that any operation under an work centre have Execution time =Set up time +Processing Time +Tear Down Time and also Inter operation time -Que time , Wait Time , Move Time .
Now when you dipatch the operation in CM21 , it cheks the available capacity on that date and also compare with the total operation timimngs within schedule start and schedule finish date and then dispach automatically if work centre is not overloaded otherwise it will pop up with a Scheduling Logg or else it will appear with an window that will show u Date , Work Centre , Operation , timie so that you can change according to WC load n availablity in alternate date .So In the strategy prfile if you click Display dates while dispatching u can obseve the same .
Now total production order schedule start and schedule finsihe date will be considered and it will automatically chage as per the WC availabli capaciy while automatic dispatch .But u need to SAVE that to observe the changes in CM21.
Hope it is clear
Regards
JH

How to setup the timeout time about container mangement transaction?

hi
i want to modify the time-out time about cantainer management transaction.
but i don't know where and how to setup it....
please tell me how to do it, thanks a lot.
Joe

We haven't been using the session pool, just the direct Jolt classes, but
the only way we've found to set the timeout is via a transaction time, it
seems to be the only one that has any effect.

Setup ports in Time Capsule

hello folks,
I replaced my old router (non TC) by a pretty new TC 3Tb.
I have installed also in my home some cameras that transmites images real time throught out internet using DYNDNS.
on my previous router I was obliged to setup some specific ports to allow outgoing internet traffic, but after install TimeCapsule, my cameras is not visible.
So the question is, Can I setup TimeCapsule to allow outbound internet traffic as my previous router ?
thanks
CarlosM

Yes, the same port forwarding rules apply..
See
https://discussions.apple.com/community/wireless/airport?view=documents
Port Mapping documentation.
But many many people are finding the port opening on the new TC / AE models is flaky.. it will not work reliably.. Welcome to the future.

How setup Airport Express time zone "Asia/Krasnoyarsk" automatically?

Hello!
I need your support to understand how AirPort Express sets time zone automatically.
I live in Krasnoyarsk, Russia. Upon connectin AirPort Express for the first time the time zone was set as "Asia/Hong Kong" and the box "Set time zone automatically" was checked. Few days later time zone automatically changed to Asia/Krasnoyarsk.
I wonder how the AirPort figured that out and why it didn't determined it just after connection? I mean why it determines it's location not instantly and how it figures out it's location without having GPS module? Can anyone tell?
PS It is not a matter of great importance but i'm very-very curious what's happening with time zone and why it behaves so strange! =))

I found the matter!
If you make a clean setup of AirPort or TimeCapsule from OS X device u have a HUGE number of locations available in your AirPort locations list - including Krasnoyarsk.
If u set up the same device (clean setup, after full reset) with a PC Airport Utility - u have only limited list of locations!
The most interesting thing - that the list of location remains uchanged until u hard-reset the device again! For example, if u had set up a device from an iMac - u will have a full locations list even if you addreess you time capsule from a PC. Vice versa - if u initially set up the device from a PC AirPort Utility - u will not have a full list of locations even if u enter it from an iMac AirPort utility afterwards.

How to setup a one-time vs. monthly condition type for billing?

Hi SD Gurus,
Our customer contracts invovle a fixed monthly charge that needs to be billed every month for the duration of the contract.
I've set this up successfully through a condition type. My condition type is setup as periodic billing.
Our customer contracts also involve a fixed one-time charge (e.g. setup fees).
My requirement stipulates that when our sales department creates a sales order, the system should automatically populate the one-time charge along with the the monthly charges.
I'm having trouble with this requirement. I would like to know how I can configure the system so that the condition type shows up only for the first month. In my configuration, the one-time fee shows up for all the months.
Thanks!

Thanks a lot for your information.
Yes, I think my command is good to setup a service.
But this service is a load balance service.
Through this service, all the connections will be put at both nodes.
Currently, my requirement is that I need a service
Through this service, all the connections will only be put at one node,
until this node damaged,
then the connections are put at another node
Do we have a way for this case?
Your service will not run on both nodes. It will run on one and failover to the other. However, a better way would be to define it as a policy manged service, which may be what you are thinking of.

BPC Optimization Server Time Out error message

We’re using BPC 7.5 MS and on patch level 111.02
There’s two front-end servers and one back-end.
When completing a full optimization with compression on an application we immediately get the optimization popup screen with no processing information only a “Server Time Out” error message.
Optimization was taking a long to time run and sometimes timed out. To try and resolve this issue we have just updated indexes and statistics and during our test in production we now receive the “Server Time Out” error message immediately. However, the records from tbl.Factwb and tbl.Fac2 did move to the tbl.Fact.
Our development environment test ran fine.
Any suggestions?
Thanks.

Hi Michael,
please look in the logs maybe you will found more informations regarding the timeout and eventually share it.
There are several notes about a timeout in 10 version,
1394533 - 'Server Time Out' error when performing Modify Application, Full Process of a dimension, or Full Optimize this is related with NLB
but it could be also related with the web.config 1628908 - How to fix Optimize with compress time-out failure
or if you reach the max number of connection
1635749 - Error Message: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool
