How many parameters to WWV_FLOW_ITEM.MD5()?

Using v2.0.0.00.49
I have optomistic locking working on a few of my pages, but I have run into the problem where I am sending too many parameters to the function WWV_FLOW_ITEM.MD5(). How many parameters does the function take?
Thanks!

How many parameters does a developer need to know like '~request_method'

<b>I am sorry to post it twice. I am not able to delete it!</b>
In SAP standard program 'RSHTTP01', "call method client->request->set_header_field exporting name 'request_method' value = 'GET'." is used. How many parameters do I need to know like 'request_method'? I cannot find any document to describe it.

As for in ABAP seeing documentation for values, simply double click (or F1) on the parameter, if there are docs available you will usually get them. If the parameter is a reference to something by double clicking you usually get taken to the item, from there you try again to double click or F1 and see what you get.
So what I did was typed your program in, in SE38 and then looked at the code and found this:
if internal is initial.
      call method cl_http_client=>create
        exporting
          host               = host_str
          service            = service_str
          proxy_host         = proxy_host
          proxy_service      = proxy_service
I assume this is where you are looking so I tried to double click on "proxy_service" - nothing, I tried F1 - nothing.
So now I look at how this is a method call so I double click on "cl_http_client" and low and behold I am taking to the method itself. Now I go to the method "CREATE" (<i>cl_http_client=>create</i>) and I click on the "PARAMETERS" button at the top of the screen next to "EXCEPTIONS" I now see a bit of information and a list of all the parameters used in the create.
From here you should be able to now play around see what all used and available with this method.

How to write a method without knowing how many parameters passed in?

hi there,
i m writing a method which is to find out the max value of a set of values, e.g.
   int max(var1, var2, var3, var4) {
      here is the code to find the max value, and return it;
......in these case, there are 4 parameters, but what i m trying to do is to write a general method can handle any number of parameters. for some reason, i can't pass in an Array, or a Collection, is there any way i can achieve it?
thank you!
best regards

for some reason, i can't
pass in an Array, or a CollectionWhy you can't pass a Collection in? I think passing a
Collection is preferred to the alternative suggestion.and I disagree. Having to build a collection first seems very clumsy. For example, using the following definition of max()
    public static int max(int a, int... b)
        for (int x : b)
            if (x > a)
                a = x;
        return a;
    }means that I can quite simple get the max of 5 values using
int max = max(4, a, b,d,21);
Now you try the same using a collection.
    public static int max(List<Integer> list)
        int max = Integer.MIN_VALUE;
        for (int x : list)
            if (max < x)
                max = x;
        return max;
List<Integer> list = new ArrayList();
list.add(4);
list.add(a);
list.add(b);
list.add(d);
list.add(21);
int max = max(list);I know which I prefer.

How many parameters can function at the same time?

Post Author: leongcy23
CA Forum: General
Dear all,
I have a situation where I need to use about 6 parameters in a report. In the Record Selection Formula Editor of the main report, I put "OR" for every parameters, which mean I can select either one of the parameter.
({DocumentHeaders.ShipVia} in ucase({?CustCode}) to ucase({?CustCode2})) or
({DocumentHeaders.SalesRep} in ucase({?Salesperson}) to ucase({?Salesperson2})) or ....(so on)
In the report itself, there are 11 subreports. But when I preview the report, its only show the correct data if I use maximum 2 parameters. If I use more than 2 parameters, the report result will be incorrect.
Here I just want to know is there any limitation for the usage of parameters in a single report?
I am using Crystal Report version 8.
Appreciate for help.
Best Regards,
Anson

Hi, thanks for the reply.
The solution that you given is sounds like I need to select / fill in every parameters in order to get the reports because you use AND in between each parameter. Does it means miss out a single parameter will cause an empty report?
Can I make a selection, for example: I fill in parameter 1, 3 & 5 in order to sort out my report information based on the parameter 1, 3 & 5 rather than fill in every parameters? My objective is to make sorting to my report based on the parameters that I'm using.
For your information, the defaut value of the parameters will be empty (" ") all the time.

Report workload by calculating how many versions of SharePoint list items created in a certain time period

I have a total of 66 SharePoint 2010 lists - yes, 66! - each lists contains between 1500 and 3200 list items. My employees update these various list items throughout their workday. Each update to a list item creates a new version of the list
item. On average each list item will have anywhere from 5 to 10 versions before it is done. I need to create a report that tells me how many list items they've updated in a certain time frame. I have come close but still cannot arrive at
the data I'm looking for.
This is what I have so far:
I've created a report using SQL Report Builder 2008 v3 where I've filtered it to show only items MODIFIED between, for example, Feb1 and Feb28. Of those records, I want the report to tell me how many versions were created during that time
frame. The result is one list item with 5 total versions. Versions 1.0, 2.0, & 3.0 were created on 12/12/14. The last two versions, 4.0 and 5.0, were created on 2/24/15. Therefore, the answer I'm looking for is 2 because they
created 2 versions between Feb1 and Feb28.
However I get the following results using these queries:
If I do a =Sum(Fields!owshiddenversion.Value) in the expression field I get the total versions which is 5
If I do a =Count(Fields!owshiddenversion.Value) in the expression field I get the instance which is 1
Is there a way to count ONLY the number of versions created in a time period? Is there another hidden field in SharePoint that I can use in the expression that will give me results I'm looking for?

Hi Rafael70,
Per my understanding that you have already get all the need fields and informaiton of the updated version of list items and now you want to calculate how many versions of SharePoint list items created in a certain time period, you can't get desired result
using sum and count function, right?
I have tried to tested on my local environment but because I am not clear what is value in the field "owshiddenversion", I assumed you have two datatype parameters (StartDate and EndDate) to help filter the report in a certain time period.
Generally, if you have add the filter correctly, it will filter the correct number's updated version in this time period, I would like you to provide details information as below to help better analysis the requirements:
Could you please provide sample data of the table.
Please provide snapshot of the report structure you have currently designed.
Please try to provide all the expression you have used.
If you still have any problem, please feel free to ask.

How can I set limitations on how many records a report can return

I have a report on the web using Oracle Reports builder and I have the client enter in date parameters for the report that they want.
Well with date ranges for different clients a different number of records are returned. Because of time it can take the report to return I want to limit the number of records that report can return.
How can I go about doing that? I don't want to limit with date parameters because date won't really work for me. I need to limit on how many records can be returned. If it exceeds 10,000 records I want the client to refine the date range of schedule the report to run later. Meaning we will run that report. So I would have two check boxes if the count was over 10,000 do you want to define your date or schedule the job to run later.
Can any one help me with this? How would I go about this?

To know if the report is going to return more than 10,000 records, you first have to run the query with a 'select count(1) from ... where ...' (with the same from and where clauses as you normal query). Since this takes about the same time as runnng your report, I wonder if you really gain anything (although formatting may take some time too).
You may simplify the select count(1) query by omitting all the lookup tables that are only needed for formatting. That way your query may run a lot faster. You can put this in your after parameter form trigger.

How many people can connect to the mail server 3

I am looking to grow my business which consist of a growing email base with emails that need to be set up and managed. How many emails can be hosted on the mac server?

Hello Thomas,
"MAXLOGMEMBERS" has nothing to do with the number of users that can connect to the instance. It is a parameter to control the number of files that can be assigned to a group of (redo) log files.
how many people can connect at Oracle XE?Well, that depends on how they connect. There are parameters controlling the number of sessions in the database. But if you have a technical user, e.g. when using APEX, there may be more users than sessions in the database...
So you need to clarify what kind of user access you mean.

How many JDBC receiver CC?

Hi all,
I am in doubt how many JDBC receiver CC I need to configure. I have many different inbound interfaces on database side (Oracle ). At first I have thought that I would need one JDBC receiver per interface, but now it seems that one CC could be enough, since there is no difference in the CC parameters. Is it correct to use one JDBC receiver for many interfaces ?
Please advice.
Thanks, Janos

Hi,
Technically it is possible to have single CC for one DB & Port however its good to have multiple channels as it will improve performance.
If you have 10 interfaces, 1 Receiver Channel with concurrency 1 then these 10 messages will be delivered to target DB in sequencial manner.
However by increasing concurrency you can do parallel processing.
If you have 10 interfaces with 10 receiver channel, all these 10 messages will be procesed parallel inspite of keeping concurrency 1.
I suggest if you have multiple messages and many interfaces, you go for different CC. If Load and no of interfaces is less, then one CC can also be sufficient.
Hope this helps.

Too Many Parameters

Hi,
I have a few methods which have quite a few parameters - in some cases about 10 or 11. None of these methods are similar in so much as to warrant a bean object being passed, but is there another alternative?
Any ideas?

warrant a bean objectdoesn't warrant a bean object eh? how ya figure that besides apathy? for example:
someObj.setColor(int, int, int)
sure that works, but doesn't
someObj.setColor(Color)
work much better in showing you what your doing here? you want to set a color, so use a color.
these many parameters your putting in, don't they represent something? like the others' said, its a bit vague to comment here... maybe you have a case where these many parameters aren't belonging to the same thing, but its hard to imagine.. even if its some flight control system that take variables from many places in wierd ways....why thats an "event" of sorts and so you can pass in an event with all that information. in j2ee httprequests, you can dump all sorts of things into a request or session and then just pass that around and get out what you need.....same thing. map, list, whatever you choose. it represents an event none the less.

Configuring data guard: how many standby redolog do I need?

Hi all, I want to add a standby databse to my RAC test environment but I don't understanad how many redolog I need.
The main db is a 2 node RAC (10.2.0.4.0); every node has 3 log groups; every log group has 2 logfile (every log group is multiplexed on DG_DATA1/ASR/ and FLASH_RECOVERY_AREA/ASR/ )
The standby db will have all its datafile on the same filesystem, so I already configured the trasnslations parameters:
DB_FILE_NAME_CONVERT='/opt/oracle/app/oracle/oradata1/ASRSB','+DG_DATA1/ASR','/opt/oracle/app/oracle/oradata2/ASRSB','+FLASH_RECOVERY_AREA/ASR'
LOG_FILE_NAME_CONVERT='/opt/oracle/app/oracle/oradata1/ASRSB','+DG_DATA1/ASR','/opt/oracle/app/oracle/oradata2/ASRSB','+FLASH_RECOVERY_AREA/ASR'
Replication via rman works well, but I have to manually add the standby redolog on the standby db and which formula to use to calculate the number of the standby redolog needed. Which is the correct formula between :
1)
# of standby log = ( # of redolog files + 1) * # of thread = (6 +1)*2 = 14 standby redolog files
2)
# of standby log = ( # of redolog groups + 1) * # of thread = (3 +1)*2 = 8 standby redolog files
thanks,
andrea

Andrea,
I think 8 should be the answer on your question. Because you have 3 log groups and 2 threads therefore (3+1)*2 = 8.
According to the documentation :
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ps.htm#SBYDB00426
Minimally, the configuration should have one more standby redo log file group than the number of online redo log file groups on the primary database. However, the recommended number of standby redo log file groups is dependent on the number of threads on the primary database. Use the following equation to determine an appropriate number of standby redo log file groups:
(maximum number of logfiles for each thread + 1) * maximum number of threads
I think you may get confused with maximum number of logfiles. But sometimes logfile is used as a synonym to log group. The actual log group files are usually called log members. (for instance MAXLOGFILES parameter specifies the maximum number of log groups and MAXLOGMEMBERS specifies the maximum number of members for each group).
Each additional member in a redo log group is just a multiplexed copy. You can also consider multiplexing the standby redo log files, the same why you do for redo log members.
In order to learn more about the usage, benefits and limitations of Standby Redo Logs (SRL) you can refer to Metalink Note 2193444.1.
I hope this helps.

How many types of transactions in ABAP

How many types of transactions in ABAP

Hi,
Transactions
The normal way of executing ABAP code in the SAP system is by entering a transaction code. Transactions can be accessed via system-defined or user-specific, role-based menus. They can also be started by entering their transaction code (a mnemonic name of up to 20 characters) in the special command field, which is present in every SAP screen. Transactions can also be invoked programmatically by means of the ABAP statements CALL TRANSACTION and LEAVE TO TRANSACTION. Transaction codes can also be linked to screen elements or menu entries. Selecting such an element will start the transaction. The term "transaction" must not be misunderstood here: in the context just described, a transaction simply means calling and executing an ABAP program. In application programming, "transaction" often refers to an indivisible operation on data, which is either committed as a whole or undone (rolled back) as a whole. This concept exists in SAP but is there called a LUW (Logical Unit of Work). In the course of one transaction (program execution), there can be different LUWs.
Letu2019s have a look at the different kind of transactions:
Dialog transaction
These are the most common kind of transactions. The transaction code of a dialog transaction is linked to a Dynpro of an ABAP program. When the transaction is called, the respective program is loaded and the Dynpro is called. Therefore, a dialog transaction calls a Dynpro sequence rather than a program. Only during the execution of the Dynpro flow logic are the dialog modules of the ABAP program itself are called. The program flow can differ from execution to execution. You can even assign different dialog transaction codes to one program.
Parameter transaction
In the definition of a parameter transaction code, a dialog transaction is linked with parameters. When you call a parameter transaction, the input fields of the initial Dynpro screen of the dialog transaction are filled with parameters. The display of the initial screen can be inhibited by specifying all mandatory input fields as parameters of the transaction.
Variant transaction
In the definition of a variant transaction code, a dialog transaction is linked with a transaction variant. When a variant transaction is accessed, the dialog transaction is called and executed with the transaction variant. In transaction variants, you can assign default values to the input fields on several Dynpro screens in a transaction, change the attributes of screen elements, and hide entire screens. Transaction variants are maintained in transaction SHD0.
Report transaction
A report transaction is the transaction code wrapping for starting the reporting process. The transaction code of a report transaction must be linked with the selection screen of an executable program. When you execute a report transaction, the runtime environment internally executes the ABAP statement SUBMITu2014more to come on that.
OO transaction
A new kind of transaction as of release 6.10. The transaction code of an OO transaction is linked with a method of a local or global class. When the transaction is called, the corresponding program is loaded, for instance methods an object of the class is generated and the method is executed.
Reward Points if found helpfull..

How many ejbCreate() can be in Session and Entity Bean???

How many ejbCreate() method can be in a Session and Entity

How many ejbCreate() method can be in a Session
ion and Entity
Bean???For Stateful Session Beans and Entity Beans, as many as you'd like.
Stateless Session beans can only have one, since their ejbCreate methods can not take any parameters.
>
>
How many can be in CMP and BMP SessionBean???If you mean CMT/BMT(Container-Managed transactions / Bean-Managed Transactions), then
the answer is the same. The create method requirements are independent of the transactional nature of the bean.
If you really mean CMP/BMP(Container-Managed Persistence / Bean-Managed Persistence) , it doesn't apply to session beans, only entity beans. However, even for entity beans, CMP vs. BMP has no bearing on the rules regarding # of create methods.

How many databases can run in a server

How many databases can run in a server, how can we find how many databases are running there – in OS level for UNIX

You can have as many oracle instances as your system resources and kernel parameters allow you to.
A quick search to know how many oracle instances are running, check the OS processes:
ps -ef | grep smon
This will list all smon manadatory instance processes, this way you'll know how many concurrently instances are running.

How many connections?

Just a quick planning question. This is a church environment that may grow quickly. They're currently trialing with three LinkSys devices and about 25 users. But they anticipate up to a couple of hundred users if successful. Which device(s) would be best for lots of connections? And how many would that be per access point?

The absolute answer is "It Depends" ... just like any other size or implementation question.
For commercial APs from Cisco, the closest thing to "rule of thumb" is ~20 concurrent users per AP, but that number can be adjusted up or down depending on the application, protocols in-use, and overall volume of traffic per user. Also keep in mind that ONE USER radiating an 802.11b signal into your coverage will (may) slow down the system and reduce the potential max count.
I would also humbly suggest you dump the Linksys and go with commercial APs, as they will have more options for fine tuning the power, coverage, rogue mitigation, monitoring, and control.
How many do you need? From the information provided, I'd say 500 or so. You can probably adjust that down somewhat according to the size of the coverage area, building materials, and a mess of other parameters ... without that info, I'll go safe and say 500 ( ;-} .
i.e., How many vehicles do I need to transport the entire senior class of my nephew's high school class at one time? We need to create a solid transportation budget.
Realistically, what you need is a solid site survey that will measure a real signal in the actual environment with real or simulated traffic that is comparable to the expected loads. There is no substitute.
If you are not prepared to do that kind of survey, you should hire someone to come in and do it for you, as this is *critical* information and can save you a mess of money (frustration, reputation) in the long run.
The site survey is where the budget meets head-on with the requested functionality. If you already have a budget planned, then expect to lose some functionality or coverage.
If you already have desires and expectations, then the site survey will provide you the information needed to come up with a reasonable and realistic budget.
As a final note: Just kidding on 500 (in case your sense of humor was broken). A proper spread of APs with the proper antennas can accommodate almost anything ... proper antennas for the coverage area is critical, and selection of same is a big part of the site survey.
Good Luck

Hello,
I am getting a new message this morning creating a view:

Any ideas on this?
