How bad is the performance hit with RTMPT?

In a conversation with engineers recently at a CDN it was suggested to me that streaming all video over RTMPT only was a viable solution to the barriers posed by firewalls and proxies blocking port 1935. They indicated that they had seen no signifigant performance degradation with tunneling and that many of their clients were making the switch from "rollover" type connection models to connection via RTMPT only.
This ran counter to my notion of the process. I have always thought the packet overhead was signifigant.
Is it? How bad is the performance hit for streaming live h.264 video?

Hmmm... That's quite a hit.
I'm trying to determine the best strategy for reaching the most people with the least performance hit. A guy lays out his strategy here:
http://www.kensodev.com/2010/02/19/rtmp-being-blocked-by-firewalls-flash-media-server/
He basically says ditch 1935. Never use it. Always use 80. Like this:
rtmp://your_ip_address:80/app_name
If that fails, do this:
rtmpt://your_ip_address:80/app_name
Does that seem valid? Does that first option avoid the perfomance hit of tunnelling while getting you more connections? If so, it makes me think there is no benefit at all to connecting via 1935.

How to improve the performance of General information in MSS

HI,
We are facing with critical performance issue in General information screen of MSS.
For one employee number of subordinates are more than 3500 and because of this no of database hits for fetching all the records are more than 20,000 and each database hit is taking some time and overall time for fetching all the records is around 2 minutes which is not acceptable.
so we want to cut down the number of hierarchy levels shown to the manager or by keeping the same number of levels how to increase the performance .
Any inputs will be highly appreciated and rewarded with points for sure
Bala Duvvuri

Hi,
We have problem in performance because when we call General information screen for managers in MSS it reads the data from HRP1001 and if manager is having more data then it will take time.
we rectified this problem by creating an index that caches all the users who have more number of objects .
we created a job that creates index and execute that every day

How to improve the performance of adobe forms

Hi,
Please give me some suggestions as to how to improve the performance of adobe form?
Right now when I' am doing user events it is working fine for first 6 or 7 user events. From the next
one it is hanging.
I read about Wizard form design approach, how to use the same here.
Thanks,
Aravind

Hi Otto,
The form is created using HCM forms and processes. I' am performing user events in the form.
User events will doa round trip, in which form data will be sent to backend SAP system. Processing will
happen on the ABAP side and result will appear on the form. First 6 or 7 user events works correctly,
the result is appearing on the form. Around 8 or 9th one, the wait symbol appears and the form is not
re-rendered. The form is of size 6 pages. The issue is not coming with form of size 1 page.
I was reading ways to improve performance during re-rendering given below.
http://www.adobe.com/devnet/livecycle/articles/DynamicInteractiveFormPerformance.pdf
It talks about wizard form design approach. But in SFP transaction, I am not seeing any kind of wizard.
Let me know if you need further details.
Thanks,

I am using Oracle 9i... You might want to start with a feature of SQL*Plus: The AUTOTRACE (TRACEONLY) option which executes your statement, fetches all records (if there is something to fetch) and shows you some basic statistics information, which include the number of logical I/Os performed, number of sorts etc.
This gives you an indication of the effectiveness of your statement, so that can check how many logical I/Os (and physical reads) had to be performed.
Note however that there are more things to consider, as you've already mentioned: The CPU bit is not included in these statistics, and the work performed by SQL workareas (e.g. by hash joins) is also credited only very limited (number of sorts), but e.g. it doesn't cover any writes to temporary segments due to sort or hash operations spilling to disk etc.
You can use the following approach to get a deeper understanding of the operations performed by each row source:
alter session set statistics_level=all;
alter session set timed_statistics = true;
select /* findme */ ... <your query here>
SELECT
         SUBSTR(LPAD(' ',DEPTH - 1)||OPERATION||' '||OBJECT_NAME,1,40) OPERATION,
         OBJECT_NAME,
         CARDINALITY,
         LAST_OUTPUT_ROWS,
         LAST_CR_BUFFER_GETS,
         LAST_DISK_READS,
         LAST_DISK_WRITES,
FROM     V$SQL_PLAN_STATISTICS_ALL P,
         (SELECT *
          FROM   (SELECT   *
                  FROM     V$SQL
                  WHERE    SQL_TEXT LIKE '%findme%'
                           AND SQL_TEXT NOT LIKE '%V$SQL%'
                           AND PARSING_USER_ID = SYS_CONTEXT('USERENV','CURRENT_USERID')
                  ORDER BY LAST_LOAD_TIME DESC)
          WHERE ROWNUM < 2) S
WHERE    S.HASH_VALUE = P.HASH_VALUE
         AND S.CHILD_NUMBER = P.CHILD_NUMBER
ORDER BY ID
/Check the V$SQL_PLAN_STATISTICS_ALL view for more statistics available. In 10g there is a convenient function DBMS_XPLAN.DISPLAY_CURSOR which can show this information with a single call, but in 9i you need to do it yourself.
Note that "statistics_level=all" adds a significant overhead to the processing, so use with care and only when required:

Do you have an idea how to improve the performance ?

Hi All,
Greeting,
I'm doing SEM IP. Regarding the performance, do you have some thought about this ?
So I have planning report for project report . As we know, if we forecast against project, means the date itself is the life of the project itself.
It means it could be more than 10 years (forecast period) and 10 years (actual period). Currently I segregate between actual and forecast into different info cube .
But the performance of the planning report is slow now. Do you have an idea about this how to increase the performance. The performance I mentioned here is when we're going to the report (after putting in the value in the selection screen).
The other question, at this moment, I have a multiprovider than this multi provider consist 2 info cubes ( actual and forecast ). Than my aggregation is sitting on top of that multi-provider .
My question whether that's approach correct or not ? Or do we have to create 1 aggregate (only for forecast), than I have multi-provider consisting forecasting aggregation and actual cube .
than my query will sit on top of that multi-provider ?
Which one is better ??
Thanks a lot all,
really need your help,

Hi,
For the performance tuning, you can consider any of the following three methods,
1. Indices
With an increasing number of data records in the InfoCube, not only the load but also the query performance can be reduced. This is attributed to the increasing demands on the system for maintaining indexes. The indexes that are created in the fact table for each dimension allow you to easily find and select the data.
2. Partitioning
By using partitioning you can split up the whole dataset for an InfoCube into several, smaller, physically independent and redundancy-free units. Thanks to this separation, performance is increased when reporting, or also when deleting data from the InfoCube.
3. Aggregates
Aggregates make it possible to access InfoCube data quickly in Reporting. Aggregates serve, in a similar way to database indexes, to improve performance.
4. Compressing the Infocube
Infocube compression means aggregation of the data ignoring the request idu2019s. After compression, the system need not perform aggregation using the request ID every time you execute a query.
And I feel that as per your scenario, you need to do first compress the data based on user requirements and have only the required data in the infocube.
And for the approach regarding the Aggregation level design, choosing between the two approaches depends on the user requirements. For example,
If you have aggregation level created on top of multiprovider containing actual and forecast cube, in your report (created on top of aggregation level) you can view the key figure values present in both the cubes, which is not possible in the other approach.
So this approach is suited if your requirement is to view the records from both the cubes in your report (Comparing planning and actual values).
The second approach is used if your requirement is only to report on planning forecast cube.
Hopes this solves your issue.

Balajee

How to improve the performance of one program in one select query

Hi,
I am facing performance issue in one program. I have given some part of the code of the program.
it is taking much time below select query. How to improve the performance.
Quick response is highly appreciated.

Waiting for quick response.
Best regards,
BDP

Bansidhar,
1) You need to add a check to make sure that internal table t_dels_tvpod (used in the FOR ALL ENTRIES clause) is not blank. If it is blank skip the SELECt statement.
2) Check the performance with and without clause 'AND lfart NOT IN r_del_types_exclude'. Sometimes NOT causes the select statement to not use the index. Instead of 'lfart NOT IN r_del_types_exclude' use 'lfart IN r_del_types_exclude' and build r_del_types_exclude by using r_del_types_exclude-sign = 'E' instead of 'I'.
3) Make sure that the table used in the FOR ALL ENTRIES clause has unique delivery numbers.
Try doing something like this.
TYPES: BEGIN OF ty_del_types_exclude,
         sign(1)   TYPE c,
         option(2) TYPE c,
         low       TYPE likp-lfart,
         high      TYPE likp-lfart,
       END OF ty_del_types_exclude.
DATA: w_del_types_exclude TYPE          ty_del_types_exclude,
      t_del_types_exclude TYPE TABLE OF ty_del_types_exclude,
      t_dels_tvpod_tmp    LIKE TABLE OF t_dels_tvpod        .
IF NOT t_dels_tvpod[] IS INITIAL.
* Assuming that I would like to exclude delivery types 'LP' and 'LPP'
CLEAR w_del_types_exclude.
REFRESH t_del_types_exclude.
w_del_types_exclude-sign = 'E'.
w_del_types_exclude-option = 'EQ'.
w_del_types_exclude-low = 'LP'.
APPEND w_del_types_exclude TO t_del_types_exclude.
w_del_types_exclude-low = 'LPP'.
APPEND w_del_types_exclude TO t_del_types_exclude.
t_dels_tvpod_tmp[] = t_dels_tvpod[].
SORT t_dels_tvpod_tmp BY vbeln.
DELETE ADJACENT DUPLICATES FROM t_dels_tvpod_tmp
    COMPARING
      vbeln.
SELECT vbeln
    FROM likp
    INTO TABLE lt_dels_tvpod
    FOR ALL ENTRIES IN t_dels_tvpod_tmp
    WHERE vbeln EQ t_dels_tvpod_tmp-vbeln
    AND erdat IN s_erdat
    AND bldat IN s_bldat
    AND podat IN s_podat
    AND ernam IN s_ernam
    AND kunnr IN s_kunnr
    AND vkorg IN s_vkorg
    AND vstel IN s_vstel
    AND lfart IN t_del_types_exclude.

How to test the performed SAP SCRIPT

Hi friends can any one help for
how to test the performed SAP SCRIPT. What are the necessary codes or anything else for performing it

Praveen,
Can you be much clear with your query? What do you mean by performing? Do you mean how to execute it ?
Regards,
Vinod.

Please help me how to improve the performance of this query further.

Hi All,
Please help me how to improve the performance of this query further.
Thanks.

Hi,
this is not your first SQL tuning request in this community -- you really should learn how to obtain performance diagnostics.
The information you posted is not nearly enough to even start troubleshooting the query -- you haven't specified elapsed time, I/O, or the actual number of rows the query returns.
The only piece of information we have is saying that your query executes within a second. If we believe this, then your query doesn't need tuning. If we don't, then we throw it away
and we're left with nothing.
Start by reading this blog post: Kyle Hailey &raquo; Power of DISPLAY_CURSOR
and applying this knowledge to your case.

How to read the 'Input help with fixed values' of domain .

How to read the 'Input help with fixed values' of domain .
The domain has a Value range i want to read those values .
Are these values stored in any table ?
Plz help me i need it ver badly...
Thanks in Advance...

Hi Chandra Shekhar,
To read the 'Input help with fixed values' of domain , you can use the function module : HR_P_GET_FIXED_VALUE_TEXT.
iIf you enter the domain name, you will find the fixed values entered in the domain.
These values are stored in a table DD07L(DD zero 7 L). Here the values are stored based on domain name.
See if it works for you.
Award points if its helpful.

How to detect the key enter with a numerical control without using loop event?

I want to accept a numerical value only when the key enter is pressed, but without using the event. How to detect the char "enter" with a numerical control?
Thanks!

When the user edits a numeric control with a keyboard, its property "key focus" is true. When the user hits enter, key focus becomes false. Poll the property to latch the control valuse at the true-false transition. That won't work if the user modify the control using up and down arrows.

Just how bad is the HD screen on the T530

Hey everyone. I'm buying a laptop for my father whose main criteria are:
Overall build quality
(backlit) Keyboard and trackpad quality
At least 15" screen
Upgradeability
International warranty and customer service
Whilst it is overkill for what he wants to do, AFAICS the T530 is the only thinkpad that fits the bill.
The only problem is his eyesight isn't what it used to be and he needs eye-glasses to read the screen on his current laptop which has a 15" 1366x768 display. Hence, a higher resolution screen is out of the question (I understand there is dpi scaling but it is never implemented perfectly across all apps).
I see people warning against the HD display all the time, so I'd like to know just how bad is the contrast, colour reproduction etc?

I understand where you're coming from however I don't mean travel like how a businessman travels. My father just spends a lot of time abroad and an external monitor will not be practical. I'm surprised no-one seems to have any experience with the HD screen. Thank you for your suggestions though.

How bad is the Verizon customer service?

how bad is the Verizon customer service? Well let me tell you. I just got off the phone with from their Finance Department, who called me, and they asked when I would be paying my bill. I answered never. He asked why. I said I had a billing dispute. He asked to go over the bill together (the first rep to do this) having going over the issues and reviewing the notes he said “oh wow”. I informed him that I filed a complaint to the BBB, FTC and FCC and filed a small claims suit against them. He said he understood why. He then said he would unsuspended my 3 lines (I have already disconnected 2 of them) and place my account in a “billing dispute status”. I said thank you. After about 30 minutes I called back when my saw my lines still suspended. Both the finance department and customer service both said the lines were still suspended both blaming the other department as a reason. Got to love the Verizon teamwork. Any suggestions?

They may have stated over the phone your account was in a "billing dispute status" however you can ONLY do so in writing.
From the customer agreement:
HOW AND WHEN CAN I DISPUTE CHARGES?
If you're a Postpay customer, you can dispute your bill within 180 days of receiving it, but unless otherwise provided by law or unless you're disputing charges because your wireless device was lost or stolen, you still have to pay all charges until the dispute is resolved. If you're a Prepaid customer, you can dispute a charge within 180 days of the date the disputed charge was incurred. YOU MAY CALL US TO DISPUTE CHARGES ON YOUR BILL OR ANY SERVICE(S) FOR WHICH YOU WERE BILLED, BUT IF YOU WISH TO PRESERVE YOUR RIGHT TO BRING AN ARBITRATION OR SMALL CLAIMS CASE REGARDING SUCH DISPUTE, YOU MUST WRITE TO US AT THE CUSTOMER SERVICE ADDRESS ON YOUR BILL, OR SEND US A COMPLETED NOTICE OF DISPUTE FORM (AVAILABLE AT VERIZONWIRELESS.COM), WITHIN THE 180–DAY PERIOD MENTIONED ABOVE. IF YOU DO NOT NOTIFY US IN WRITING OF SUCH DISPUTE WITHIN THE 180-DAY PERIOD, YOU WILL HAVE WAIVED YOUR RIGHT TO DISPUTE THE BILL OR SUCH SERVICE(S) AND TO BRING AN ARBITRATION OR SMALL CLAIMS CASE REGARDING ANY SUCH DISPUTE.
Simply send in a notice of dispute form. Since you have already filed a "small claims case", I would think it may be unnecessary, though, but it can't hurt to be thorough.
