ADF Mobile - Phone Performance Issues

Hello,
I've been using ADF Mobile for a while now. All's going well - I'm able to access web-based data services etc and everything seems to work. I do have a couple of couple of questions regarding performance on the phone though and I was wondering if anyone could offer some help/advice etc.
I've followed all the steps here: https://blogs.oracle.com/mobile/entry/configuration_tips_for_better_performance
...but with no visibile improvements. My issues are:
<1> Once the app is deployed, starting it for the first time takes around 2 minutes. All subsequent start-ups of the app after this take a couple of seconds, even after a shutdown of the phone. I'm not sure how to determine what exactly is happening during this phase, and why this takes so long just the first time? The duration for this also seems to have increased as I've added pages to my app, and as it only has 4 at the moment I'm concerned that adding much more to it will make the problem worse.
<2> I use "listItems" on most pages in a "panelGroupLayout", and the scrolling performance is very poor. All other apps I have on my phone scroll very smoothly. With my ADF app, you drag your finger to scroll up or down and there's a noticeable delay before all the rows move in one go with no visible scrolling actually taking place. This happens even when all the rows to be displayed are loaded on to the page and there's no more calling of the web service necessary. I've deployed the sample "DeviceDemo" to my phone and the "Properties" page has the same problem. The scrolling is very poor.
I've done a fair bit of Googling on this without much success, Any help or suggested reading on any of this would be very much appreciated.
Cheers, Rich.

Currently there is no 'solution' for this problem.

Hi
First you would need to deploy the application in "Release Mode". This requires you to create a Java Keystore and a certificate using the Java keytool, and then you would use it to compile the app. If you have done that, then can you please help explain what these pages are doing, and observed performance?
Unfortunately Galaxy Tab 2 is a bit old - if you have done everything to optimize the app, this could be due to older Android OS. Android OS (especially version 2.x) does not support HTML5/JS well, and performance is much worse than HTML5/JS running on Android 4.x devices. This is more than just HW differences - this is primarily due to the web engine used by the webview.
This is also somewhat a general issue with Android - Chrome is a much faster browser on Android, but unfortunately the webview (which ADF Mobile leverages) is not yet based on Chrome. If and when they switch to Chrome, the JavaScript/HTML5 support would start to rival that of the iOS.
Thanks,

ADF mobile Client App: Issue about using db sequence for populating row_id

Hi,
I'm working on an ADF mobile client app POC project. In the mobile app, new record can be created, the column type for row_id is VARCHAR2(15), I used the db sequence created in MC db, converted the seq number to a string, then set row_id via initDefaults method.
The new records are created and row_ids are set with the proper sequence numbers when first time launching the client app in blackberry simulator. But if I exit the app and re-launch the app again, I got net.rim.device.api.database.DataTypeExpection when trying to create a new record.
Could anyone please help me and let me know what could cause this issue? What should be the proper way to populate the row_id? Appreciate your response in advance!

using 10gR2 on Sun-Solaris. Getting consistently "db file parallel read" over 35 ms as an average wait for the past few months. No performance issues as such.
Using RAID 1+0. DB Size is 2 TB. Transactions are OLTP/Batch
Is this metric high or normal. How to justify that..
Looking at your results it's not really possible to say.
db file parallel read is a request for a number of randomly distirbuted blocks, and the time for a read is the time for the last block of the set to be returned.
Without knowing how many blocks are being requested at a time you can't really determine what constitutes a reasonable time. Given that you say OLTP + Batch, and have a large volume of scattered reads, it's quite possible that you have some queries on the Batch side doing very large index range scans - which would allow for some very large db file parallel reads.
I take it from the use of statspack that you're not licensed for the diagnostic and performance packs; it would be easy to query v$active_session_history to get some idea of the number of blocks per request as this is given by the P2 parameter. As it is. you may be able to get a rough idea by messing about with the various "physical read" numbers in the Instance Activity section of statspack.

ADF-JSF: Application Performance Issue

Hello!
My question or set of questions will be a bit vague...I am simply not sure where to look for problem(s). So here is what I have. Application implemented with ADF-JSF (JDEV ver:10.1.3.2.0). It basically has 5 pages. Each page containes user input form, commandButton and result table. Functionally, each page is a 'search page' that returns results based on what user specified in the form. Components on each page are bound to VO that is based on EO (DB table). Tables have at least 2.5M records up to 16M. Certain indexes exist (for most common searches) to improve the performance. However, there have been performance issues found and largely they would be grouped into the following:
1. User is on page A, performs the search, goes to page B (via link) and performs other search, then goes back to A and similar search takes much longer to return results. Seems to me that this moght be related to memory. Maybe results of the previous search are cashed and it takes new search to retreive results longer as the VO cashe needs to be cleared first. Does that make sense?
2. User is on page A and then goes to B. Leaves browser for 10-20 minutes and tries to go back to A. It takes up to a minute before page reloads with the previously displayed results. I am thinking this has to be related to page lifecycle where AM tries to re-execute bindings ( I do not think it is passivation issue though). What is the best practice to control the lifecycle?
Any pointer on where to look for the solution is very welcome.
Rade

Carl,
To use Tom Kyte's analogy, you are firing a gun into a room full of people hoping to hit the bad guy. You haven't seemed to have gotten any information about where the performance issues lie. It could be in the DB, network, ADF Business Components, JSF layer, other stuff monopolizing resources, etc, etc. I have ADF BC apps developed in 10.1.3.3 that run quite well.
So, I would recommend you spend some time investigating where the performance problems lie. Try turning on logging output, check machine utilization - use your investigative techniques to find the bad guy so you can then work on fixing him.

ADF Mobile bundle extension issue

Hi
I've just installed adf_mobile_bundle extension in Jdeveloper (as described here https://blogs.oracle.com/brunoborges/entry/first_steps_with_oracle_adf).
It seems ok,but jdeveloper ,once, restarted doesn't reflect the changing expected : no ADF mobile application , no evidence in the >tools>preferences form.
do i have done something wrong?
Regards
Max

thank for your prompt response but it doesn't work.
I'm newbie so it might be possible that i have doing something wrong. For istance it sound strange me see that jdeveloper, once specified the folder and the file adf-mobile_bundle.zip doesn't execute any setup step. It just shows me some information about the licence and after having clicked OK it suddenly asks to restart..I mean , I should have expect at least a run of unzip step, install process..stuff like this or jdeveloper waits the restart for doing this?
Regards

Oracle ADF Mobile application is very slow in Android

Hi
I am new to oracle ADF.
When I tried to deploy an application in an android device it takes a lot of time to deploy as well as every button click in the application takes more time to load. Is there any way to speed up the deployment process ?

And this one as well

Lumia 800, performance issue when listening to mus...

I am using Spotify on Lumia 800. If I use any network using apps (IE, FB, Twitter) the music will pause playing (actually the play stutters) while it's getting data from internet. It happens even if I am using WLAN and I am listening to offline playlist, so it's definitely not a bandwith issue rather than phone performance issue. Any steps I could try to work around this?
Solved!
Go to Solution.

It's an issue with the spotify app, it's in need of a major update to correct issues like this. It behaves like this on non-nokia windows phones too.
The workaround I use is to make tracks available for offline listening.

Issues in ADF mobile application using Trinidad components

I am facing the following issues when developing a mobile application using trinidad components :
Jdev version : 11.1.1.6
1) I dont see a date component using trinidad components? The dev guide http://docs.oracle.com/cd/E23943_01/web.1111/e10140/sup_comp.htm says that tr:inputDate is supported but when i try to drag a data field to jsf page i don't see an option for Trinidad date component. so i went ahead and created an af:inputDate in the page. But the date selection dialog doesnt open up.
2) i tried using 'Rendered' for conditional rendering of a component but it does not work or refresh immediately, the same problem is solved in my adf application using visible property but looks like there is no 'Visible' property for Trinidad components. any work around?
3) i wanted to have a 'create insert' call in my task flow before launching the page. Since Task flows are not supported in ADF mobile application, i have added 'ADF Faces' also into my project and created task flow and jsff page as i do for a adf web application the only diff being the usage of trinidad components in my jsff page. is this fine? Also can we mix trinidad components and adf components into the same page?
4) I have a tr:inputText on a clob input text field which i am updating in ADF page using a clob converter class. Same thing i cannot do for trinidad text as it is resulting in null pointer exception. any solution to update clob fields into database which uses tr:inputText compents.
Help to solve any one of the above issues (by quoting serial no) would be highly appreciated. Thanks.

HT201401 I am writing to bring to your attention a serious issue I had with your product. My brother bought one iPhone 4, 16 gb mobile phone from US last year and gifted me in India. but it couldnt be serviced in India why ?

Hi,
I am writing to bring to your attention a serious issue I had with your product. My brother bought one iPhone 4, 16 gb mobile phone from US last year and gifted me in India. In few months it had a problem with its home key. I took the phone to service service center and they told me that your phone is having hardware problem and as the phone is under warranty cannot be replace in India. You can come back when this is out of warranty. Now few days back when i walk again to the service center they stated that this phone we cannot repair here in India because of this phone purchased from US.
This a total disgraceful service from such a big brand like apple.
I hope to hear back from you about this incident.
Sincerely,
Niranjan
<Personal Information Edited by Host>

No iPhone has a international warranty. Warranty is valid only in
country of original purchase. Since iPhone was bought in the US,
you must return the iPhone to the US. That means you must personally bring
the iPhone to Apple in the US or send it to a friend/relative in the US for them
to take to Apple. After replacement, your friend can ship it back to you. Shipping
and insurance costs are your responsibility.
Apple does not accept international shipments for evaluation/repair
and will not ship replacements out of the country.

WRT400N mobile phone issues

hello! I seem to have an odd issue with my router....Setup went through fine, I have it broadcasting a G and N network. The N network is awesome, the G is also running smoothly with all devices...EXCEPT mobile phones. My computers and Xbox run great off the wireless G...anytime a mobile phone connects it give it service for like 30 sec- 2 minutes maybe then drops it. The phone stays connected but says no internet service. You have to disable wifi on the device and reconnect it again to get another 30 sec of service before it repeats. I thought it was my device...but anyone with a mobile phone experiences the same. Is there some setting I can play with to remedy this?
BTW it does have the latest firmware. Thanks for any input!!

This "maybe" a bug. Can you try it using iphone?
Try refalshing the firmware and then the 30-30-30 reset rule.
Yesterday is history. Tomorrow is mystery. Today is a gift.

I am using iphone 3gs, I upgraded my i-os to 6.0 from 5.1.1 however I am facing performance issue, along with this all the applications including settings or any other shuts down automatically. Is there any way by which I can use my phone in better way?

No, downgrading from any version of iOS to an earlier version is not supported.

Performance Issue : Why does ADF Taskflow Portlet (JSF bridge portlet) loading ADF Specific images, css, js everytime from portlet producer with dynamic URL with portlet_id and context parameters?

Hi All,
We have used WSRP Portlet in Webcenter Portal Page. The Portlet is created using JSF Bridge out of ADF Bounded Taskflow.
It is causing Performance issue. Every time static content like js, css and images URLs are downloaded and the URL contain portlet_id and few other dynamic parameters like resource_id, client_id etc.
We are not able to cache these static content as these contains dynamic URL. This ADF Specific images, js and css files are taking longer time to load.
Sample URL:
/<PORTAL_CONTEXT>/resourceproxy/~.clientId~3D-1~26resourceId~3Dresource-url~25253Dhttp~2525253A~2525252F~2525252F<10.*.*.*>~2525253A7020~2525252FportletProdApp~2525252Fafr~2525252Fring_60.gif~26locale~3Den~26checksum~3D3e839bc581d5ce6858c88e7cb3f17d073c0091c7/ring_60.gif

Technologies Used:
Webcenter Portal PS6
Jdeveloper 11.1.1.7
Please suggest , how this performance issue can be resolved?
Thanks.
Regards,
Digesh

Strange...
I can't reproduce this because i have issues with creating portlets... If i can solve this issue i will do some testing and see if i can reproduce the issue...
Can you create a new producer with a single portlet that uses a simple taskflow and see if that works?
Are you also using business components in the taskflows or something? You can try removing some parts of the taskflow and test if it works so you can identify the component(s) that causes the issues.

8961 phone having issue receiving and calling mobile phone

Ext XXX is having issue receiving and calling mobile phone. It stated that 'Download Status -Failed' attached is the screenshot of the error in Cisco Unified CM Administration. Any idea where to look into?
If i want to grab the log, should be from Trace & Log Central under CUCM?

Phone goes "offline" for about 7-10 minutes at a time (every couple of hours) usually in the afternoon (near ~60% charge).
In an office most of the day with coverage going from 4 bars to 0 bars every few minutes or so. I never miss or drop a call though given the appearance of erattic signal. RSSI usually -83. EvDO and 1x will flicker on and off througout the day. WiFi is on all the time with WPA2. Bluetooth is on without anything connected. I will sometimes get the issue if I wander out of WiFi range (out for lunch)
Reseting the phone will clear the problem. Toggling the Airplane, WiFi, and Bluetooth on/off dont clear the problem.
I have:
- Exchange calendar setup with owa.mailseat.com (I believe they have Exchange 2003)
- Google standard calendar (personal)
- Google standard shared calendar (wifes)
My wife has a Pre as well and to my knowledge has never had the phone offline problem. (I would certainly hear about it if she did )
She has:
- Google standard calendar (personal)
- Google standard shared calendar (mine)
* No exchage setup.

Serious Performance issue in ADF?

Hi Everyone,
My Jdev version is 11.1.2.3.0.
I have developed one ADF application and deployed into web logic server.
I am accessing this page through url in one portal of client.
After clicking on the page link in portal it opens the page and the page has search page(test field, submitbutton and result table).
On clicking on submit button sometimes the result in the table comes in few seconds and sometimes it takes few minutes.
its a very serious performance issue.
What should i do to increase performance for my ADF page?
why it takes much time sometimes?
Please give suggestions.
Thanks.

Hi Kumar,
Try to ensure proper indexes are placed based on search criteria in base table which will definitely increase the performance. Be sure to check the explain plan to see the performance of query instead of just running it in toad. If you feel everything is good from back end, you can tune your view object, go to view object editor->tuning and set the page range size=25 or some smaller value and see if that increases the performance.
Refer below link for more guidelines:

ADF Mobile Deployment issue

Hello -
I am so frustrated with the ADF Mobile deployment. I have already created couple of Android Apps using the native language and never faced problems like this. I am very familiar with ADF development as well.
Anyways this is my problem.
I downloaded the sample adf mobile app from the following tutorial, but I was unable to deploy it on the Android emulator in Release mode. The debug mode takes for ever.
Oracle JDeveloper 11g Release 2 Tutorials - Building Mobile Applications with Oracle ADF Mobile
This is the error messages I am getting:
[11:02:51 PM] ---- Deployment started. ----
[11:02:51 PM] Target platform is (Android).
[11:02:51 PM] Beginning deployment of ADF Mobile application "Employees" to Android using profile "Android3".
[11:02:51 PM] Deployment cancelled.
[11:02:51 PM] ---- Deployment incomplete ----.
[11:02:51 PM] The following Android preference configuration is missing or invalid. Set these options in JDeveloper Preferences on the ADF Mobile panel:
Key Password
(oracle.adfmf.framework.dt.deploy.android.deployers.ValidatePreferencesDeployer)
I generated the keystore using keygen per the tutorial and it doesnt't help.
This is how I validated the keystore.
C:\Oracle\MiddlewareMob\jdk160_24\bin>keytool -list -keystore emp.keystore
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 1 entry
empl, Nov 19, 2013, PrivateKeyEntry,
Certificate fingerprint (MD5): 8A:27:53:64:B3:AF:01:CA:9C:2F:47:2A:50:16:E4:40
C:\Oracle\MiddlewareMob\jdk160_24\bin>
I tried recreating the keystore couple of times, but it didn;t help. I know the password entered is correct.
Any suggestions will be appreciated. Also, I started learning JQuery Mobile in parallel.
Thanks,
-S
