Best environment configuration practice

we are deploying three different web applications which use bdbxml. they do not share data at all. we currently have it configured for all three apps to use the same environment but with different containers. we are running into problems where if one app goes down, it could take the entire environment down.
is a 1:1 application to environment configuration a best practice? or is sharing one environment the best practice?
thanks.

Hi,
This is the normal recovery process. If process 2 was in the middle of something, there is potential corruption on the db. So when process 2 rejoins the env with DB_RECOVERY, it will set the panic bit and start recovery. Process 1 is detecting that and getting out of the environment. After process 2 finishes up with recovery, process 1 can rejoin. This is the normal recovery process. Since we are a library, we have to be cautious about what we are doing and assume when some process terminates abnormally that something could be wrong.
You can put different Container into different environments. OR adding that the DB_REGISTER and DB_FAILCHK flags can help reduce the number of occurrences when such panic events happen. It's worth following the reference guide documentation starting here:

  • Best APEX developing practices?

    Hello,
    I have a simple question - What are the best APEX developing practices in regards to developing workspaces ?
    There are two ways to develop in APEX (when you create an application for internal use, of cause) :
    One is to have a workspace per Application - Meaning that you have Developing, Test and Production Application in the same Workspace, and this Workspace would be reserved to one application only. The advantage of this approach is that it is easy to move ready pages (or even the whole application) from Developing to Production - You can simply copy ready pages from one application to another.
    The other one is to have a Workspace per Environment - Meaning that you have all your Production applications in one Workspace and all the Development application in another Workspace. In this case, when you have to move a page to Production, you have to export it, and import it to another Workspace. The advantage of this approach is security - you don't work in production...
    So I wanted to ask APEX gurus - What is your opinion on that? Are there any Oracle standards for developing in APEX? What is your best working experience in regards to developing applications in APEX, etc..??
    Thank you!

    Hi Sloger
    Keep it simple DEV, TEST and PROD are on separate database instances, preferably on separate servers.
    If you only have one box, then develop your app on your PC using XE.
    You can have the same workspace id on multiple databases, allowing you to promote between databases easily using SQL*Plus.
    As far as on app per workspace, that's entirely up to you.
    Multiple applications in a single workspace work very well - after all this is how the APEX team builds the Application Builder.
    Regards

    HI,
    For your home testing you might need a latest technology to get a smooth and fast installation. i7 processor might be the ideal with memory at least 8GB. if you're planning to have more than 3 VMs running at the same time than you need 12-16GB memory at least.
    From my experience installing on vm and allocated memory 2.5GB each VM the installation could take 15-30minutes

    Hi, I have a Macbook (mid 2007) with 1 GB ram and I would like to upgrade. Currently I have 2x512MB, so both of my memory slots are taken. Is it a good idea to have one 512MB card and a 2GB card in the other slot? Otherwise, what is the best RAM configuration for a mid 2007 macbook?
    I am also looking into purchasing this memory card for my macbook, is this a good choice?

    the maximum amount of RAM your laptop can take is 3.3GB. So while you can physically insert 4GB of RAM, OS X will only be able to see 3.3GB of it.
    But I don't know how knowledgeable that poster is who says it can utilize 3.3 GB. I do know that the full 4 GB shows up in the System Profiler on my MacBook Core 2 Duo 2.16 GHz.

    Loyalty functionality in sales order
    Solution
    Please read the documentation below Setup for Integration of Sales Order with Loyalty for CRM 7.0 You can use this note to integrate the loyalty application with sales order to allow customers to earn reward points on purchase of products, redeem points and buy point products. To enable the above-mentioned functionality, the following set up has to be carried out in the system: -> Product master data You have to add SetType REWARD_PRO_LOY (created for product type Material) to the product category. You may create a new product category for loyalty products. You can add the settype to a product category using the following steps: 1. Use transaction COMM_HIERARCHY
    2. Search for the category to be used for loyalty products
    3. In the SetTypes tab under Category Data, add REWARD_PRO_LOY as the settype After the settype is added to the loyalty product category, it will appear as point information assignment block in the product overview page. Here, you can maintain point information for Accrual, Redemption and Buy Points scenarios. You have to select the Scenario, Point Type (Points, Miles etc) and enter the associated number of points. The following three activities are supported: -> Accrual
    In this scenario, a customer buys standard products and earns reward points for his purchase. The actual points to be accrued will be maintained at product master data level.  You have to select EARN as the loyalty scenario. Example: We have a product, Laptop T 61, which has 1000 reward points associated with it, at the product master level. If a customer buys this product a member activity will be created and 1000 points will be credited to his account. Note: You can maintain points for a product with a particular loyalty scenario in the point information assignment block of product overview page. -> Redemption
    In this scenario, a customer redeems his points to buy products. In CRM 7.0, redemption products have 100% discount and can be bought only by points. The point value of such products will be maintained at product master data level in point information assignment block. You have to select REDEEM as the loyalty scenario. Example: We have a keyboard HT-1010, which has a price of 5000 points (and 100% discount). If a customer buys this product, a member activity will be created and 5000 points will be deducted from the customer's account. -> Buy Points
    This functionality enables a customer to purchase points. The point value of such products will be maintained at product master data level under the point Information assignment block. You have to select BUYPOINTS as the loyalty scenario. Note:
    Point information is maintained for 1 base unit of product .If the quantity and unit of measure are changed, the points will be calculated accordingly. 
    -> Customizing in SPRO You have maintained the following customizing settings in SPRO: 
    -> In the customizing activity Define Point Types for Sales-Order Integration, you maintain point types. For more information, see SAP Customizing Implementation guide   Customer Relationship Management  Marketing  Loyalty Management - Design  Channel Integration  Define Point Types for Sales-Order Integration Point Information in product master can be maintained only for these point types. 
    -> In the customizing activity Define Categories and Types for Sales Order Integration, you maintain member activity category, activity type, sales order status for which activity will be created and the processing delay ( Process On Hold) for a particular loyalty scenario. For more information, see SAP Customizing Implementation guide  Customer Relationship Management  Marketing  Loyalty Management - Execution  Member Activities  Define Categories and Types for Sales Order Integration 
    -> In the customizing activity Define Transaction Types, you maintain the transaction types for accrual, redemption and buy points. For more information, see SAP Customizing Implementation guide  Customer Relationship Management  Transactions  Basic Settings  Define Transaction Types Note:
    Reference transaction types LTAA, LTAR and LTAB are delivered for CRM IC and UIU. For web channel, transaction types ISLA, ISLR and ISLB are delivered. You can create new transaction types on project basis but transaction classification should be maintained as A, R and B for accrual, redemption and buy points transactions respectively. For redemption transaction LTAR, the item category is LTAR where the pricing process is maintained as 100% discount. Therefore, the net value will always be 0 for redemption items and only points will be charged. You have to maintain the condition 0R10 in pricing procedure. The pricing procedure 0CRM01 contains the details of condition 0R10. If you do not maintain 100% discount, then additional currency price will be displayed. For example, $200 + 100 MILES. Billing and delivery related customizing has to be done on a project basis. ----------------------------------------------------------------------------------------------------------------------------------------------
    ----------------------------------------------------------------------- Setup for Integration of Sales Order with Loyalty in EhPx for CRM 7.0 You can use this note to integrate the loyalty application with sales order to allow customers to earn reward points on purchase of products, redeem points and buy point products. To enable the above-mentioned functionality, the following set up has to be carried out in the system: -> Product master data You have to add SetType REWARD_PRO_LOY (created for product type Material) to the product category. You may create a new product category for loyalty products. You can add the SetType to a product category using the following steps: 1. Use transaction COMM_HIERARCHY
    2. Search for the category to be used for loyalty products
    3. In the SetTypes tab under Category Data, add REWARD_PRO_LOY as the SetType After the SetType is added to the loyalty product category, it will appear as point information assignment block in the product overview page. Here, you can maintain point information for Accrual, Redemption and Buy Points scenarios. You have to select the Scenario, Point Type (Points, Miles etc) and enter the associated number of points. The following three activities are supported: -> Accrual
    In this scenario, a customer buys standard products and earns reward points for his purchase. The actual points to be accrued will be maintained at product master data level.  You have to select EARN as the loyalty scenario. Example: We have a product, Laptop T 61, which has 1000 reward points associated with it, at the product master level. If a customer buys this product a member activity will be created and 1000 points will be credited to his account. Note: You can maintain points for a product with a particular loyalty scenario in the point information assignment block of product overview page. This is an optional activity. In many cases, the points accrued will not be maintained in the product master data but will be determined based on reward rules. In such cases, you do not have to maintain the SetType. -> Buy Points
    This functionality enables a customer to purchase points. The point value of such products will be maintained at product master data level under the point Information assignment block. You have to select BUYPOINTS as the loyalty scenario. This activity is mandatory for Buy Points scenario. -> Redemption
    In this scenario, a customer redeems his points to buy products. In CRM 7.0, redemption products have 100% discount and can be bought only by points. The point value of such products will be maintained at product master data level in point information assignment block. You have to select REDEEM as the loyalty scenario. Example: We have a keyboard HT-1010, which has a price of 5000 points (and 100% discount). If a customer buys this product, a member activity will be created and 5000 points will be deducted from the customer's account. Note:
    Point information is maintained for 1 base unit of product .If the quantity and unit of measure are changed, the points will be calculated accordingly. Redemption functionality in Ehp1 for CRM 7.0 In case of redemption, you have three payment options to choose from. You choose the payment option in the customizing activity Define Mixed Payment for Sales Order Integration. For more information, see SAP Customizing Implementation guide   Customer Relationship Management  Marketing   Loyalty Management  Channel Integration  Define Mixed Payment for Sales Order Integration a) Fixed redemption value from Product Master
    The point information will be picked from the SetType as explained above and 100% discount will be given at item category level. Attached is the screenshot of the same. Using Pricing Process, you can select whether normal pricing is executed or 100% discount is given. In addition to the above-mentioned setting, a 100% discount condition should be included in the pricing procedure. For this purpose, you can use the standard condition 0R10 in the pricing procedure. b) Mixed redemption using Conditions and IPC With Ehp1 for CRM 7.0, mixed payment functionality is available. This enables a consumer to pay with points and money in a single sales transaction. You can maintain point prices as conditions in product master data under the Prices assignment block. The condition type
    0LM1 with condition tables SAP002, 003 and 004 are used to maintain these point conditions as seen in the screenshot below. Select the option '0LM1_LM_SAP002' from the dropdown. Select 0LM1_LM_SAP002 from the dropdown. In the above screenshot, Price in Points = 100% point price , Max Price in Points = maximum points a consumer can spend, Min Price in Points = minimum points a consumer should spend for this product. Note:
    In the above scenario, entries in Point Information assignment block will not be considered for redemption but the information will be picked from the conditions. A new usage LM is developed for points as conditions. You can use the customizing activity Condition Technique: Basics to develop condition tables, access sequences, condition types and point procedures.
    For more information, see SAP Customizing Implementation guide   Customer Relationship Management  Master Data  Conditions and Condition Technique  Condition Technique: Basics You can create condition objects with application CRM and usage LM. The point procedure 0LM001 is delivered and can be used in a sales transaction using the below the customizing Determine Point Procedures. Point information will be fetched by executing this procedure. For more information, see SAP Customizing Implementation guide   Customer Relationship Management  Marketing  Loyalty Management  Channel Integration  Determine Point Procedures You can assign this point procedure to a particular sales org, distribution channel, division, customer pricing procedure and document pricing procedure the same way it is done with pricing procedure. If you decide to use only points in a sales transaction (consumer has to pay 100% point price always), a standard pricing procedure with 100% discount would suffice. If you want to allow mixed pricing, for example, a consumer can pay anything between 1000 to 2000 points and rest in currency, then condition type 2902 (point based discount) should be included in the pricing procedure and 100% discount should not be chosen at item category level as explained above. The conversion rate between points and currency can be maintained in CRM UI in the following manner:
    1. Go to Loyalty Management
    2. Select Prices
    3. Choose 2900 as the Price Maintenance Group
    Attached is the screenshot of the same. Here 1 USD is maintained as 1 point. Product specific conversion rates are also allowed. Condition type 2901 is the reference condition type for 2902 and 2903 (used in flexible order and is described later in the section flexible order). Scales can be maintained for the conversion rates. For example, for the first 1000 Points it is 0.5 USD per point. From 1000 to 2000 points, it is 0.75 USD per point and from 2000 points onwards, it is 1 USD per 1 Point Example of Sales order Here, a product TV-1000 is maintained with Point price as 1000 Miles and Min Point price  as 500 miles and Max point as 1000 Miles. A consumer purchases this product using a redemption transaction and spends 500 points. With a conversion rate of 1 USD equal 1 point, the net value becomes 500 USD + 500 Miles. If consumer spends 1000 Miles, the net value will be 0 USD + 1000 miles. Similarly, various combinations of maximum price and minimum price can be maintained in Product master and accordingly consumer can use his points to redeem products. c) Mixed payment using Flexible order If you do not wish to maintain point prices for individual products due to high volume of products, specifically in retail, then they you select this option where during the checkout, consumer will be given the option to use his points. Discount will be given based on the points spent at an item level. In this case, the only thing you have to maintain is a fixed conversion rate (condition type 2901). The transaction type will be the same as accrual. For example, a consumer purchases a product HT-1000 on which he can earn 1000 special points. During checkout, he will be asked to use his points. Use Point Payment will be enabled, and he can enter points he wants to redeem. If he decides to use 500 points, then a discount will be given to him based on the points spent. Here, with a conversion rate of 1 USD equal to 1 point, 500 USD discount will be given and accrual information will be lost. Hence, the points spent will be equal to 500. Discount Based on Member Basic and Lifetime Tiers In accrual transactions, discounts can be given to members who have reached a particular tier (Basic and Lifetime tiers). This can be maintained as a condition using the following steps:
    1. In CRM UI, go to Loyalty Management
    2. Select Prices
    3. Choose 29MD as the Price Maintenance Group
    Here, we can maintain the percentage discount on a product for a particular basic and lifetime tier. The condition type 29MD should be included in the pricing procedure of sales transaction to provide discounts. In sales order processing, you can check the discount under the assignment block Price Totals on the overview page. In this case, a 2% discount is given based on the above condition as shown in the third row) Generation of Billing Documents Once a sales order is created and saved, you can generate a billing document as a follow up activity. For loyalty sales transactions, the following three new fields are added to the billing document.
    -> Points
    -> Point type
    -> Points spent In Accrual and Buy Points scenarios, Points = Points accrued; Point type = Miles, points etc; Points spent = 0 In redemption scenarios, Points = Total point price; Point type = Miles, Points etc; Points spent = points spent by the consumer To generate billing document from a sales order, you have to select a relevant billing option for the item category. In this case, we have selected Transaction-Related Billing According to Order Quantity. The billing will happen via CRM Billing.
    Note: Only CRM Billing is currently supported
    As billing will happen only if the order is replicated successfully to ERP (where shipping, delivery and logistics will be done), you have to ensure that all the master data, for example, products, BP (sold to party), conditions, etc are present in ERP along with the transaction type and item category (for example, LTAA and LTAN). Once replication is complete, we can create a billing document from the sales order overview page. Select Create Follow-up and choose Billing. -> Customizing in SPRO You have maintained the following customizing settings in SPRO: 
    -> In the customizing activity Define Point Types for Sales-Order Integration, you maintain point types. For more information, see SAP Customizing Implementation guide   Customer Relationship Management  Marketing   Loyalty Management  Channel Integration   Define Point Types for Sales-Order Integration Point Information in product master can be maintained only for these point types. 
    -> In the customizing activity Define Categories and Types for Sales Order Integration, you maintain member activity category, activity type, sales order status for which activity will be created and the processing delay (Process On Hold) for a particular loyalty scenario. For more information, see SAP Customizing Implementation guide  Customer Relationship Management  Marketing  Loyalty Management  Member Activities  Define Categories and Types for Sales Order Integration 
    -> In the customizing activity Define Transaction Types, you maintain the transaction types for accrual, redemption and buy points. For more information, see SAP Customizing Implementation guide  Customer Relationship Management  Transactions  Basic Settings  Define Transaction Types 
    Note:
    Reference transaction types LTAA, LTAR and LTAB are delivered for CRM IC and UIU. For web channel, transaction types ISLA, ISLR and ISLB are delivered. You can create new transaction types on project basis but transaction classification should be maintained as A, R and B for accrual, redemption and buy points transactions respectively. For redemption transaction LTAR, the item category is LTAR where the pricing process is maintained as 100% discount. Therefore, the net value will always be 0 for redemption items and only points will be charged. You have to maintain the condition 0R10 in pricing procedure. The pricing procedure 0CRM01 contains the details of condition 0R10. If you do not maintain 100% discount, then additional currency price will be displayed. For example, $200 + 100 MILES. Billing and delivery related customizing has to be done on a project basis. -> In the customizing activity Assign Product Hierarchy for Sales Order Integration, you register the product hierarchy if it is not the same as sales operation hierarchy. For more information, see SAP Customizing Implementation guide  Customer Relationship Management  Marketing  Loyalty Management  Channel Integration  Assign Product Hierarchy for Sales Order Integration This customizing will help you create reward rules based on product categories and process them during creation of member activity using sales order. -> In the customizing activity Determine Pricing Procedure, you maintain 29CRLM as the pricing procedure for loyalty transactions. For more information, see SAP Customizing Implementation guide  Customer Relationship Management  Marketing  Business Functions  Pricing  Pricing in the Business Transaction  Determine Pricing Procedure For more information please refer to the attachment and IMG Documentation.

  • Web Service Best and Worst Practices within Oracle SOA Suite

    Hi All,
    Has anybody got a single document that concisely details the best and worst practices around the design of web services for oracle SOA and BPEL.
    I'm interested the following aspects
    1. Level of Granularity
    2. Level of Reuse
    3. BPEL orchestration. numbers of BPEL process vs services
    4. Transport choices...SOAP vs REST vs Big Services etc
    5. Activity Monitoring with BAM
    6. Future proofing of signatures and ongoing maintenance and process change
    I'm constructing a document myself to share on this forum, but i'd be very interested to use the wisdom of others if somebody has done this before...
    Thanks in advance :)

    This is a question best answered by your Oracle reseller or Oracle account manager to give you all the details but I hope this brief answer helps:
    - The Unified Business Process Management Suite (BPM Suite 11g) includes: BPM Studio, BPM Composer, BPMN Service Engine and Workflow Extensions, BPM Process Spaces, and BPM Process Analytics.
    - BPM Suite 11g requires the licensing of SOA Suite 11g for Oracle Middleware which requires a license for WebLogic Suite.
    - You can license SOA Suite 11g now and license BPM Suite 11g later.
    Since the products are layered, I don't see this cutting into SOA sales at all. My personal view is that BPM on top of SOA is brilliant since it provides easy integration between human and automated tasks, builds on many of the SOA concepts that are key for a successful BPM implementation (functional, not the Oracle product), and uses the same IDE. The synergies extend past easy use of services; the same business rules and human workflow components are used between both products.

  • Best Raid Configuration for a 8-1tb hhd server

    Hi All,
    I have been trying to figure out what would be the best raid configuration for my Windows 2012 essentials server. So I was wondering if I could get some advise on this. Here is what I would like to get out of this configuration.
    I would like to split the 8-1tb drives into 2 VHD one with about 300gb for the OS to be installed on, and the rest to be use  for storage. I want like to have good redundancy, fairly good read & write capabilities.
    I will be using this server for a Small Web Page and Game Hosting, Email Exchange, Critical Application hosting.
    I would like the ability to enlarge the overall raid storage by swapping out my 1Tb drives with 2Tb or larger as the need for more storage arises.
    Any help would be greatly appreciated,
    Thanks

    You may be better of using Storage spaces and not using raid at all.

    In the registry, hkey_local_machine\SYSTEM\currentcontrolset\services\Forte
    Environment Manager 3.0.F.2\Parameters, there are three values. One of
    these is "Command line". You can add specific values there. For example,
    you might want to specify the name server address there with the "-fns"

    Another way that I have done this is to use the SRVANY tool included with
    the NT resource kit to run a .BAT file as an NT service. The .BAT file sets
    the appropriate environment variables and then starts the node manager. The
    benefit of this approach is that any FTEXECs started by the node manager
    inherit this environment.

    i am new to coherence and i developed a web application. in my app coherence is a cache and berkely db is a backend store. i configured the coherence-config.xml correctly as per the instructions in the oracle site.the problem is when i try to put my data in the cache i am getting an exception like this
    java.lang.NoSuchMethodError: com/sleepycat/je/EnvironmentConfig.setAllowCreate(Z)V

    i google it but i got the answer for setting the environment in the java class(even this is also not succeed).i dont know how to do it for coherence. how coherence will take the berkely db configuration when i load the data in catch.please help me. if you know the answer please show the code how to configure the berkely db environment configuration for coherence and where i need to chanage/create and what should i have to do coherence will invoke the berkely db environment and store the data in the local disk. i am using coherence 3.6 with weblogic 10.3.5 server

    Hi Thank you very much. Its works fine with je 3.3 version. I have several doubts.as per my application configuration its stores the data in local disk using berkely db. when i restart the server the cache data is no more but the stored data is available in the disk , is there any configuration or technique is available for pre load the data from disk to catch. (i am using replicated cache scheme).if yes menas please provide the full detail and sample code. thanks in advance.

  • Best environment to do Kernel Hacking?

    What is best environment to mess around with kernel? Which distro or, if virtually, on which virtual emulator?
    I tried to build a 3.2.5 on Arch installed in virtualbox (since I didn't want to mess up my installed arch on computer) and it is taking forever to compile...
    I was reading somewhere that some people are able to compile kernel in few minutes. I am wonder how they did it, just because of good computer specs?

    No fancy stuffs needed, so I can built the kernel in less that 10 minutes.
    For ARM with Qemu.
    You had to create your own file-system somehow?

  • What is the best RAID configuration for a MacPro as a Logic User?

    There ought to be a universal answer to this question: what is the best RAID configuration for Logic Mac Pro users? I will be more specific.
    I use Logic Studio, Reason, Ableton, and Motu Symphonic Instrument simultaneously.
    I want to fail safe my precious audio files and improve performance as the system reads/writes data from multiple files, from audio tracks to digital samples.
    I want to run video files simultaneously to do nifty audio soundtracking to video.
    Here is the configuration I have in mind.
    HD 1: OS and Logic Studio, Reason/Ableton samples etc. software (non-raid) (250 GB)
    HD 2/3: MIrrored RAID set for AUDIO FILES (500 Gb identical pair)
    HD 4: Video files / Bouncing (1 TB)
    Makes sense right? A disk for reading software. A pair of 500 GB disks for reading/writing audio files and sessions in mirrored array. A 1 TB disk for video and bouncing. The main question I have is, for audio files only, is striped or mirrored better? 64K blocks the best? And are there any more details. I assume to do this in Disk Utility.

    Well, both Mirrored and Striped have their pros and cons. If you use mirrored, it will offer no better performance than the spec'ed drive along with it's sata bus speed. The plus point is, if one drive goes down, you have the second as a backup as the complete contents of one drive are mirrored on the other.
    With striped you will get a performance boost because all files (for example a single project) will get written across both drives and hence split the load on the drives and the SATA busses. The drawback is that you'll have to make sure you have a good, regular backup schedule in place because when one of the drives goes to drive heaven, you're going to be stuffed without a full backup of both drives.
    Exactly what performance boost you'd get will depend on your project, number of files, size of files, fragmentation of files, track count etc. You may find it would be easier to use the 3 drives straight, with no raid and have:
    HD 1: OS and Apps. No samples at all.
    HD2: Audio Files for Logic projects
    HD3: Reason, Ableton, Logic etc instrument sample library
    HD4: Video and bouncing.
    Which is what I ended up doing although I use HD4 as an interchangeable backup for HD1 and 2.
    There is no universal answer to this as each must make their own choice based on their preferences and needs. Mirrored will give you full backup but on-site, in machine backup. Not much good if something untoward and drastic happens to the physical machine. I think a few people toy with striped RAID but fall on the side of using the drives straight, as in their projects they don't see a big enough gain over splitting the data across your 3 remaining drives without RAID. Studios that seriously consider raid often go out and get a dedicated raid that can offer more variations than raid 0 or raid 1 (Striped and Mirrored) and better throughput.
    I hope this helps a little and not just added to the dilemma.

  • How best to configure the memory allocation

    Hi,
    Anyone could advise how best to configure the memory allocation by setting up
    the value for
    -Xms
    -Xmx
    -XX=NewSize
    -XX=MaxNewSize
    -XX:SurvivorRate
    -XX:MaxPermSize
    for weblogic Express 8.1 and the server has about 4G RAM ?
    Thanks.

    and see how it goes.
    for weblogic Express 8.1 and the server has about 4G RAM ?This is way too much for a single weblogic instance. Normally 512-1024Mb
    is enough. I'd consider partitioning it to multiple instances with that much
    of memory. Lesser memory means faster GC.

  • Best efficient general practice for serial communication

    hello,
    when talking to a serial instrument, do you have to insert millisecond waits in the while loop or will the reading and writing from the instrument generally control the loop speed of the loop?  On the basic read write example they feed in the Bytes at Port into the VISA Read.... is this making the VISA not read until those bytes are avilable? I'm wondering if this was in a while loop if the loop would only iterated once the VISA has executed the read... which in turn depends on whether the bytes are avilable at the port?
    I'm trying to figure out a general best practice way of setting up a serial device in an effecient manner, for something where you send a write then read.... in the basic serial read write example there is a delay in-between the write and read... is this an arbitrary number? does it need to be there if you're not reading until a specified number of bytes are at the port anyway?
    much thanks!

    As far as I use the serial VI's for communication I do not use Loops, I do use loops when I need to send a bunch of query commands. Bytes at port just gives a count that how many bytes are there at the port, even if you don't use it and wire byte count in read VI you must get the response, but you will not be sure whether you have recieved exact data. Time delay between write command read response also depends on how the protocol is setup.
    I would always prefer VISA configure -> Bytes at port -> Read (this will empty any previous buffer)-> Visa write -> Bytes at port -> Visa read -> Visa Close.
