Tuxedo Performance Analysis - Query - tried txrpt not receiving report
Hi All,
We have currently migrated from Solaris-8 - Tuxedo 8 environment to Solaris 10 - Tuxedo 11gr1 Staging environment.
All the application binaries were running fine.
However we conducted a performance testing for 500 users we could see the performance coming down, when compared to our old performance report of
Solaris 8 - tux8 environment.
However we doubt it may be some issue with the network or some other server via which the requests are hitting or responses leaving our system.
Can you suggest any utility or its usage by which we can check that our current Tuxedo version is working fine than the older one?
Like how much time tuxedo is taking now to process,the throughputs.
can you please suggest some way to monitor or generate some sort of report to compare tuxedo 8 performance and Tuxedo 11g R1 performance for same application.
tried the txrpt
I5_RQMG_0002_00
SRVGRP=AQUREQGRP
SRVID=2000
CLOPT="-r -s PSY_MG_0002_00:I5_RQMG_0002_00 -o logs/slog/I5_RQMG_0002_00.out -e logs/slog/I5_RQMG_0002_00.err"

for this above server :

I get the above file generated.
Executed the command:
tuxconsolas1:/apps/tuxapps/intserv/logs/slog>txrpt -nPSY_MG_0002_00 -d05/29 -s02:00 -e14:00 I5_RQMG_0002_00.err > txrpt.out
I am just receiving :

START AFTER: Tue May 29 02:00:00 2012
END BEFORE: Tue May 29 14:00:00 2012
in the report and the process hangs for me.
Am i doing any error?

Hi,
If you want detailed performance analysis of your Tuxedo 11gR1 application, you can use TSAM (Tuxedo System and Application Monitor) to get very detailed performance information including time spent on network links, time spent waiting in IPC queues, etc. Unfortunately you won't be able to use the same tool for your Tuxedo 8.0 application as it is too old for TSAM to support.

Performance of query. Indexes not used
Hi all,
I have a select statement which is quite simple and straight forward. I join Accounts, Transactions and Customers to get some records for processing.
Query looks something like this
Select
a.x,
a.y,
a.z,
t.p,
t.q,
t.r,
c.m,
c.n,
c.o
from
accounts a, transactions t, customers c
where t.account_id=a.account_id,
and t.customer_id=c.customer_id
and transaction_date='1/2/2009'
Account's primary key is ACCOUNT_ID,
Transaction's primary key is TRANSACTION_ID
and
Customers' primary key is CUSTOMER_ID
I am having the where clause on primary keys and hence I expect to do a INDEX scan's rather than a full tablescan. However, from the explain place I see that there is a full table scan on accounts.
I removed all the three columns from accounts table in select statement (a.x,a.y and a.z) and I see that it is just doing a index scan rather than full table scan.
Is there a reason why full table scan happens if I include the columns?
Kindly suggest.1) Can you use the \ tag to preserve white space?
2) Can you use DBMS_XPLAN to generate the plan?
3) The plan you posted doesn't appear to have a filter on TRANSACTION_DATE
4) I don't understand the comment "We are comparing it to a date itself". The query you posted initially is comparing TRANSACTION_DATE to a string. If you are comparing TRANSACTION_DATE to a date, the query you posted initially must not really be what you are executing.

5) Oh, and a quick look at the estimated cardinalities seems to indicate that your statistics are wildly out of whack if the 1.5 - 2 million figure you quote is correct. -
I have multiple apple ids was backing up everything to iCloud from iPhone 5. I just bought iPhone 6 and perform a iCloud restore. I received a message that all files did not restore. How can I restore apps, files manually?
Yes - I connected my phone to my computer / Itunes and went into the apps section, but from there I have no idea how to manage the push notifications. I even tryied going into itunes that is installed on my phone. I still cannot find anyplace to manage these popups. I have also gone into settings - notifiations - and tried turning all notifications for these apps all off but that didnt work either. Any guidance is MUCH appreciated - Im not sure where to go from here.

I performed the update on my iphone and now I can NOT receive email, it just keeps trying to retrive? Any suggestions?
Hi ElizabethAnnT,
Welcome to the Support Communities!
With the Mail app open on your iPhone, notice which email account is showing in the top left corner of your screen. Tap on that mailbox and you should be taken back to the main MAILBOXES window. See the picture below:
If you tap the Edit button in the top right corner of your screen you will see a list including "All Inboxes" and "Unread." Make sure there is a blue circle with a checkmark to the left of all of these.
For more information on using Mail, click on the link below:

I'm trying to create a persona account for: (Email removed by mod) but when I try to sign up after I've entered my e-mail and new password, I do not receive my confirmation e-mail (after repeated attempts).
The original url you gave me was: http://www.mozilla.org/en-US/persona/ which is in the first screenshot I provided. If I am in the totally wrong place, it is because that is where I was recommended to go.
I cannot login with my email and password, for as I stated in the beginning, I'm not receiving the confirmation email message that validates my email address in order to create a Persona account. -
I cannot send MMS from an iphone 5 - some people it works others do not receive it. MMS is turned on and i have tried to reset phone etc - still same problem.
Are the messages successfully sent?
If so, what happens to a message after it is successfully sent has nothing to do with the cell phone that sent the message. -

Using osx 10.7.5 can send but not receive emails. Mail server support rep tried everything
Using iMac with OSX 10.7.5. Can send but not receive emails. No problem with internet account. Server rep tried everything and suggested perhaps a corrupted file in the op syst. Any ideas?
You may have a corrupt preference. Mail - Preferences - Accounts - click the offending account and re-enter all prefereneces. Also you can use Apple's OS X Mail: Troubleshooting sending and receiving email messages located at:

I initially created my apple account years ago. I am trying to reset my security questions because my answers are continually incorrect. I pressed the link that sends reset security questions info to my alt. address, but I have not received the email with instructions. I have resent the email several times and checked both of the emails I have set up with my apple account to no avail. I have tried everything that is provided in the support article about the issue and my problem has not be resolved. I've even deleted my alt email from the apple account and then reassigned it and tried again, however, I still have not received the email. Without knowing the answers to my security questions, I cannot purchase anything from the iTunes store, which I have been trying to do.
I do not know what the problem is and I am asking for any resolutions. Please and thank you!Go to the Apple ID Security site from http://support.apple.com/kb/HT5699 or call the AppleCare support number from http://support.apple.com/kb/HE57 and ask to speak with the Account Security Team...either can help you reset your questions/answers.

hi I want to change your e-secret questions because I forgot the answers I have tried sending reset questions on my mail and I have not received mail
New mail that I want is [email protected]
Alternative to the Old oneFrom King Penguin
If you have a rescue email address set up on your account then you can try going to https://appleid.apple.com/ and click 'Manage your Apple ID' on the right-hand side of that page and log into your account. Then click on 'Password and Security' on the left-hand side of that page and on the right-hand side you might see an option to send security question reset info to your rescue email address.
If you don't have a rescue email address set up then go to Express Lane and select 'iTunes' from the list of 'products' in the middle of the screen.
Then select 'iTunes Store', and on the next screen select 'Account Management'
Next choose 'iTunes Store Account Questions' or 'iTunes Store account security' (it appears to vary by country) and fill in that you'd like your security questions/answers reset.
You should get an email reply within about 24 hours (and check your Spam folder as well as your Inbox) -
I have tired deactiving my device from icloud online, I have had my contacts delete me and re-add me as a contact. I have also had them try deleting our entire message thread and starting a new one. I also had them hold down message and select "send as regular text" 3-5 times. I tried texting stop to some number I found in another discussion thread. NOTHING HAS WORKED. I called Apple support who claims they cannot help me. My service provider just refers me to apple. And now, some of my contacts no longer have the option to "send as regular text" when they hold down the messges to me! Please, please help me!
Hi Chris,
Thanks for the response. I contacted Apple at the link you listed and spoke with a representative. We walked through the steps I took in my first post above to ensure I had done them correctly. He didn't offer any new suggestions other than making sure my contacts turn on their MMS before texting me.
Unfortunately that is not working either. I tested this with several friends and I am still not receiving their messages. They get a response immediately upon texting me that says the message was undeliverable. They are able to receive my messages, I just don't get theirs.
Any other ideas?
It's mind boggling that Apple has made this such a difficult transition. There should not be repurcussions for choosing to discontinue the use of their product. The only other thing I can think to do is have my service provider change my phone number... what a nightmare. -
All of a sudden I am not receiving one of my gmails on my Mac mail account. I have a mobile me account, a cox account, a different gmail account and they all seem to be working. I tried deleting it and adding it again. No luck. Not sure what happened. I get the emails on my iphone and ipad just not coming in on my desktop for some reason. Any suggestions?
I actually deleted the account and re-added it as an IMAP account and it seems to be working. No idea why. My other account is still a POP account, but it never had any issues. Oh well. I'm getting them again on my desktop. Thanks for the response though!

I have atempted to gift a song to someone. I have been charged for it but it was not received. I tried to re-gift it and was charges a second time but the recipient still has not received it. How can I get the song to her or my money back?
First, have the recipient check any anti-spam filters that may be present on her email account or in any email application to make sure that messages from Apple aren't being blocked. If she is sure that is not the case, go here:
http://www.apple.com/support/itunes/contact/
and follow the instructions to report the issue to the iTunes Store.

Hi,
I want some "Performance Analysis Notes or material"..
Plz give me some links or send me on my id: [email protected]
Thanks...Hi, this may help you.
1) Dont use nested select statements
2) If possible use for all entries in addition
3) In the where addition make sure you give all the primary key
4) Use Index for the selection criteria.
5) You can also use inner joins
6) You can try to put the data from the first select statement into an Itab and then in order to select the data from the second table use for all entries in.
7) Use the runtime analysis SE30 and SQL Trace (ST05) to identify the performance and also to identify where the load is heavy, so that you can change the code accordingly
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/5d0db4c9-0e01-0010-b68f-9b1408d5f234
ABAP performance depends upon various factors and in devicded in three parts:
1. Database
2. ABAP
3. System
Run Any program using SE30 (performance analys) to improve performance refer to tips and trics section of SE30, Always remember that ABAP perfirmance is improved when there is least load on Database.
u can get an interactive grap in SE30 regarding this with a file.
also if u find runtime of parts of codes then use :
Switch on RTA Dynamically within ABAP Code
*To turn runtim analysis on within ABAP code insert the following code
SET RUN TIME ANALYZER ON.
*To turn runtim analysis off within ABAP code insert the following code
SET RUN TIME ANALYZER OFF.
Always check the driver internal tables is not empty, while using FOR ALL ENTRIES
Avoid for all entries in JOINS
Try to avoid joins and use FOR ALL ENTRIES.
Try to restrict the joins to 1 level only ie only for tables
Avoid using Select *.
Avoid having multiple Selects from the same table in the same object.
Try to minimize the number of variables to save memory.
The sequence of fields in 'where clause' must be as per primary/secondary index ( if any)
Avoid creation of index as far as possible
Avoid operators like <>, > , < & like % in where clause conditions
Avoid select/select single statements in loops.
Try to use 'binary search' in READ internal table. Ensure table is sorted before using BINARY SEARCH.
Avoid using aggregate functions (SUM, MAX etc) in selects ( GROUP BY , HAVING,)
Avoid using ORDER BY in selects
Avoid Nested Selects
Avoid Nested Loops of Internal Tables
Try to use FIELD SYMBOLS.
Try to avoid into Corresponding Fields of
Avoid using Select Distinct, Use DELETE ADJACENT
