Help-SD card & performance issues.

Hi I'm new to these forums and to Blackberry in general. I just recently purchased the Curve 8330 through Verizon. I wanted to store some music as well as photos and maybe some video. I did some research on using an 8GB card and found that my curve is compatible. I bought the card (sandisk) through Amazon. I put about 4GB worth of music on it and put it in the Blackberry. The music works just fine, but now the devise is very slow, about a 1-2 second delay from the time you push a button, type or scroll until it actually performs that particular function. It also seems to be acting a bit strange. I have taken the card out for now and it is working just fine. What gives? Can someone help?
Solved!

Hi Bifocals,
I have the same problem on my BB 8330 v4.3.0.124 (platform 3.1.0.71). The media card I installed is a Sandisk 4G Micro SDHC. When the media card is blank, my BB is fine. After uploading mp3 songs, pictures and video, my BB is very very slow or locks up.
I tried to pull the battery out and reinserting it to restart the BB. My BB does a security scan when restarted to read the media card. Once restarted, it works fine temporary then locks up or operates very very slow. In order to get my BB operating properly, I reformatted (FAT32) the media card connected through my PC via Desktop Manager. I tried to upload media on the card again but I ended up with the same locking problem.
My BB content security is disabled and password is also disabled. Why is the BB performing a security scan when media is uploaded on the card then locks up or operates like a turtle?
Thank you,
Ray

Help with Video Performance Issues using Flash

Asking on behalf of a customer who has been unable to get any answers so far - are you able to help?
Background:
We have a port of our Game Development Kit which allows us to recompile all our games using Crossbridge (http://adobe-flash.github.io/crossbridge/) into SWF without any code modifications.
Overview:
Our framework is using OpenGL for rendering and we have successfully ported it along with the audio and video to run in Flash.
We are experiencing performance issues using Video. We cannot use image sequence as some of the video animations are too long and would increase the download to an unacceptable size. Assets vary between 256x256 - 1024x1024 videos.

Here's the rest of the story. Let me know if you can see any resolution, and I will connect him to the forums. Thank you.
Current Video Solution:
We create an instance of NetConnection, NetStream, and Video according to most samples out there, and invoke draw to rasterize the Video DisplayObject into a BitmapData instance.
The BitmapData instance has a fixed color component layout which is not compatible with Stage3D texture and is therefore has to be reformatted before uploaded to Stage3D Texture (See Code Listing below).
Our Problems:
Performance issues with RGBA conversion (either using copyChannel or manually reformatting is not fast enough) natively in as3; this required for stage3d texture.Copying each channel individual using bitmapdata.Copychannel seems faster, but not significantly faster.
Cannot detect when video frame has been updated, therefore we may copy pixels that are not needed in enterframe (processpixel).
Looping video, our current solution uses the NET_STATUS event Buffer empty; Is there a better way to loop videos than checking buffer and seeking to 0.
Stepping video, loading FLV or MP4 side by side assets from HTTP or embedded does not support stepping? Is there another way?
ActionScript Code Listing:
video_nc = new NetConnection();
video_nc.addEventListener(NetStatusEvent.NET_STATUS , onConnect);
video_nc.addEventListener(AsyncErrorEvent.ASYNC_ERROR , trace);
video_nc.connect(null);
// OnConnect Event:
this.ns = new NetStream(e.target as NetConnection);
eventclient = new Object();
eventclient.onMetaData = onMetaData;
this.ns.client = eventclient;
ns.play(flvfile);
ns.pause();
//onMetaData event:
this.width = infoObject.width;
this.height = infoObject.height;
this.textureWidth = NextPowerOfTwo(this.width);
this.textureHeight = NextPowerOfTwo(this.height);
cliprect = new Rectangle(0, 0, this.width ,this.height);
cliprect.x = 0;
cliprect.y = 0;
cliprect.width = this.textureWidth;
cliprect.height = this.textureHeight;
totalFrames = infoObject.duration * infoObject.fps;
this.hasAlpha = true;
if(infoObject.videocodecid == 5)
this.hasAlpha = true;
this.bitmapData = new BitmapData(this.textureWidth, this.textureHeight, hasAlpha, 0xff000000);
this.video = new Video(this.width, this.height);
this.video.attachNetStream(ns);
this.video.addEventListener(Event.ENTER_FRAME, processPixels);
// processPixel method:
BitmapData.draw(video);
GLAPI.instance.glBindTexture(GLAPI.GL_TEXTURE_2D,this.textureId);
var fmt:uint = GLAPI.GL_ARGB;
// converting pixels using copychannel or loop through pixels
GLAPI.instance.glBindTexture(GLAPI.GL_TEXTURE_2D,this.textureId);
GLAPI.instance.glTexImage2D(GLAPI.GL_TEXTURE_2D, 0, fmt, this.textureWidth, this.textureHeight, 0,fmt, GLAPI.GL_UNSIGNED_BYTE, 0, convBitmapData.getPixels(cliprect));

Camileo X Sports - SD card performance issue - too slow

Hello,
can anybody help me please.....when i tun on the cam and make the FIRST record it always shows me that the speed card is too slow, but i have sandisk 64gb extreme with 48mbs.....but it only dissapears at the first record and not the following.
what can i do....i have also the newest firmware.

yup! I had the same problem at first, i have the Samy EVO class 10 32G SDHC.
It's usually brilliant, actually it works fine with the 50 fps, 30 fps and even the 720p 120 fps.
However i found the problem easier than most people simply due to sheer coincidence.
I left the screen on while recording and right before i stopped recording (btw it never froze in my case it just stopped recording) and the screen displayed "low speed card"! what do you know!
I researched the issue and it turns out the Samsun EVO was a bit slower than what the camera required at 60 fps. at 50 fps it barely stopped recording once.
SanDisk Micro SDHC Extreme Class 3 32GB SDSDQXN-032G-G46A
This card is a relatively cheap one, it is a UHS class 3 which mean it's an Ultra High Speed card. The class 3 is a great ranking. It's like 10 Euros more expensive than the Samsun and from what i've read works great with the GoPro hero 4 while shooting 4K & 1080p at 120 fps so it should hold up very well.
It was never the upgrade or downgrade of the software. Lucky i left the screen on!

Video Card performance issue

Hi,
I've notified a bug regarding the switch between the dedicated and integrated video card in my Mac. Assume that the Intel HD is used. Do CMD + SHIFT + 4 (this is the shortcut to make a screenshoot). The cursor is blinking when I move it. Do the same but assure that the dedicated video card is used: the cursor does not blinking. Do you have the same behavior ?
Thanks.

If the MacBook's iPhoto Library hasn't been upgraded by v.11, yes. Do you still have the installer for iPhoto 09? If you do, then delete the iPhoto application, it's associated preference files and the upgraded Library. Install 09, move the Library from the MacBook and then launch iPhoto 09.

Question about a view I created to fix the performance issues

Dear alll;
I have this interesting problem. I created a view to help solve certain performance issue I have been having with my query
see view below
create or replace view view_test as
Select trunc(c.close_date, 'YYYY-MM-DD') as close_date, t.names
from tbl_component c, tbl_joborder t
where c.t_id = t.p_id
and c.type = 'C'
group by trunc(c.close_date, 'YYYY-MM-DD'), t.names
;and I tried testing the view out by using the following syntax and I am getting the following errors
select k.close_date, k.names from view_test k
where k.names = 'Kay'
and k.close_date between to_date('2010-01-01', 'YYYY-MM-DD') and to_date('2010-12-31', 'YYYY-MM-DD')however, I am getting the error messages below
ora-o1898: too many precision specifiersI have googled it and tried a lot of stuff online but I cant fix the problem unfortunately and I dont know why.

Hi,
Instead of
trunc(c.close_date, 'YYYY-MM-DD')say
trunc (c.close_date, 'DD')Oracle apparantly gets confused by saying you want to truncate (or round) to two or more different units.
If it were up to me, I would allow it, since truncatng to the year implies truncating to the month and to the day (not to mention hours, minutes and seconds), but there may be reasons why that would be a pain to implement. (Maybe because there are units, such as 'WW' and 'IW', that are not neat sub-divisions of larger units.)

BPC 7 performance issue with Microsoft 2003 vs Microsoft 2007

Hi All,
Needs some help with our performance issues with BPC 7 on Microsoft 2007. We have noticed a significant difference between the two versions. When running the same report on BPC 7 MS 2003 it takes roughly around 5-6 min. When running the same report in BPC 7 MS 2007 the report takes roughly 15-20 min. We've tried numerous things to figure out what can be causing this but does anyone have the same issue or shed some light as to what i can do to eliminate this problem?
Thanks,
Elmer

Hi,
Did you install the following component on your application server (which is a prerequisite for running Excel 2007)? This note is part of the installation guide:
In order for the software to function correctly in Excel 2007, you must install the Microsoft Office 2007 system driver Data Connectivity Components, which you can get from the Microsoft web site. The components must be installed on the Application server. We recommend that you install all of the latest Microsoft Windows hotfixes prior to installing the Administration client. For information about which hotfixes to install, see http://www.microsoft.com/downloads/details.aspx?FamilyID=7554F536-8C28-4598-9B72-EF94E038C891&DisplayLang=en.
Hope this will help.
Kind Regards,
Patrick

Performance issue sdxc card adapter

Hi,
I have Macbook (2012). I am using Virtualbox for running Windows XP and Windows 8. Originally I started off saving the virtual harddrives on my internal SSD, but after a while they just consumed to much space on my HD. Thus I moved them to an external harddrive that is via firewire connected to my Apple device. Still everything worked fine and the performance was okay.
Later I had the need to think of more mobile solution. I thought placing my virtual harddrives on an SD card might be a very mobile idea. So I headed for PhotoFast Memory Expansion Combo Kit (like nifty drive, etc...). That is actually just a tiny adapter for micro sd cards that fits perfect in the sdxd slot of my Mac.
Anyhow, I moved the virtual disks to a SanDisk 64 gb SDXC Class10 u1 AND since then they perform ugly slow! Why? Do you have any hints regarding that performance issue?
What I have tried:
- Reformating the SD card (exFAT, HFS+)
- Tick "SSD" in the properties of virtual box
- using a different SDXC adapter in the USB slot
Nothing helped ;-( Do you have any idea how to improve the perfomance of my internal SDXC reader?
Thanks in advance.
Ciao tom

EP6 sp12 Performance Issue, Need help to improve performance

We have a Portal development environment with EP6.0 sp12.
What we are experiencing is performance issue, It's not extremely slow, but slow compared to normal ( compared to our prod box). For example, after putting the username and password and clicking the <Log on> Button it's taking more than 10 secs for the first home page to appear. Also currently we have hooked the Portal with 3 xAPPS system and one BW system. The time taken for a BW query to appear ( with selection screen) is also more than 10 secs. However access to one other xAPPS is comparatively faster.
Do we have a simple to use guide( Not a very elaborate one) with step by step guidance to immediately improve the performance of the Portal.
Simple guide, easy to implement, with immediate effect is what we are looking for in the short term
Thanks
Arunabha

Hi Eric,
I have searched but didn't find the Portal Tuning and Optimization Guide as you have suggested, Can you help to find this.
Subrato,
This is good and I would obviously read through this, The issue here is this is only for Network.
But do you know any other guide, which as very basic ( may be 10 steps) and show step by step the process, it would be very helpful. I already have some information from the thread Portal Performance - page loads slow, client cache reset/cleared too often
But really looking for answer ( steps to do it quickly and effectively) instead of list of various guides.
It would be very helpful if you or anybody( who has actually done some performance tuning) can send a basic list of steps that I can do immediately, instead of reading through these large guides.
I know I am looking for a shortcut, but this is the need of the hour.
Thanks
Arun

Performance issue on query. Help needed.

This is mainly a performance issue. I hope someone can help me on this.
Basically I have four tables Master (150000 records), Child1 (100000+ records), Child2 (50 million records !), Child 3 (10000+ records)
(please pardon the aliases).
Now every record in master has more than one corresponding record in each of the child tables (one to many).
Also there may not be any record in any or all of the tables for a particular master record.
Now, I need to fetch the max of last_updated_date for every master record in each of the 3 child tables and then find the maximum of
the three last_active_dates obtained from the 3 tables.
eg: for Master ID 100, I need to query Child1 for all the records of Master ID 100 and get the max last_updated_date.
Same for the other 2 tables and then get the maximum of these three values.
(I also need to take care of cases where no record may be found in a child table for a Master ID)
Writing a procedure that uses cursors that fetches the value from each of the child table hits performance
badly. And thing is I need to find out the last_updated_date for every Master record (all 150000 of them). It'll probably take days to do this.
SELECT MAX (C1.LAST_UPDATED_DATE)
,MAX (C2.LAST_UPDATED_DATE)
,MAX (C3.LAST_UPDATED_DATE)
FROM CHILD1 C1
,CHILD2 C2
,CHILD3 C3
WHERE C1.MASTER_ID = 100
OR C2.MASTER_ID = 100
OR C3.MASTER_ID = 100
I tried the above but I got a temp tablespace error. I don't think the query is good enough at all.
(The OR clause is to take care of no records in any child table. If there's an AND, then the join and hence select will
fail even if there is no record in one child table but valid values in the other 2 tables).
Thanks a lot.

Not sure I understand the problem. The max you are getting from the above is already the greatest out of the three - that's why we do the UNION ALL.
Here's sample code without output, maybe this will clear it up:
with a as (
select 10 MASTER_ID, to_date('12/15/2008', 'MM/DD/YYYY') LAST_DTE from dual UNION ALL
select 20 MASTER_ID, to_date('12/01/2008', 'MM/DD/YYYY') LAST_DTE from dual UNION ALL
select 30 MASTER_ID, to_date('12/02/2008', 'MM/DD/YYYY') LAST_DTE from dual
b as (
select 10 MASTER_ID, to_date('12/14/2008', 'MM/DD/YYYY') LAST_DTE from dual UNION ALL
select 20 MASTER_ID, to_date('12/02/2008', 'MM/DD/YYYY') LAST_DTE from dual UNION ALL
select 40 MASTER_ID, to_date('11/15/2008', 'MM/DD/YYYY') LAST_DTE from dual
c as (
select 10 MASTER_ID, to_date('12/07/2008', 'MM/DD/YYYY') LAST_DTE from dual UNION ALL

select 40 MASTER_ID, to_date('12/13/2008', 'MM/DD/YYYY') LAST_DTE from dual
select MASTER_ID, MAX(LAST_DTE)

select MASTER_ID, LAST_DTE from b UNION ALL

Experiencing strange performance issues after a hard drive failure - Help!

I bought my mid-2012 i5 Macbook Pro in December of 2012. I realized when shopping for computers that I wanted an SSD installed, but that it would be a lot cheaper if I bought the SSD and installed it rather than customizing it in the Apple Store. So I bought a nice Samsung 128GB SSD (820 or 840 - can't remember which) and did the installation. I went ahead and installed two 4GB sticks of RAM while I was at it. Everything was just dandy: my boot time was just under 9 seconds, and all of my data-heavy apps booted in no-time at all. Then all **** broke loose.
About two weeks ago, I opened my computer and I got the dreaded "? File Folder" notification with a gray screen. I immediately thought hard drive failure. No matter how many times I tried to boot, the computer just would not talk to the SSD anymore. I used Internet Recovery to get into my Disk Utility, and the entire partition was gone. I assumed the worst but wanted to be sure - I bought a hard drive enclosure and hooked the SSD up to an older Macbook, and lo and behold: it worked perfectly. I was not only able to recover data, but I could write data to the drive. Nothing appeared wrong with the drive when I plugged it into the old Macbook, but my newer Macbook still would not recognize it. Even my fiance's Windows 7 PC recognized the drive as "?" (since it was formatted for Mac, but hey - it recognized that it existed!).
I decided to re-install the original HDD that came with the 2012 Macbook Pro (the one I removed in favor of the SSD). I was able to re-install the OS and I can boot up at will, but everything is different. The performance issues are extremely noticeable. I can't have more than two programs running at one time without the spinning wheel of death appearing. My boot time went from 9 seconds to 2 minutes. I know that SSDs increase performance, so there is some slight performance downgrade to be expected since I am using a mechanical drive now -- but these are not normal issues. Sometimes I can't even type a web address into Safari without the wheel appearing. iTunes, and specifically the App Store, take minutes to open - and I have no media is on iTunes.
Here's the thing: I have tried just about anything to fix this problem that Google can pull up. I've verified the HDD, I've booted into Safe Mode, reset RAM and cache, run benchmarks and other performance tests, entered all sorts of weird language into Command Prompt, and studied Activity Monitor - I can't find a single red flag that would indicate anything being wrong. It appears to be a perfectly functioning, updated computer.
I'm thinking a piece of hardware failed that triggered the error with the SSD. I'm not really sure though since all of my performance tests indicate perfectly functioning hardware. I'm a little afraid to take it to the Apple store because I know they'll tell me it's my fault for opening the computer and replacing the hard drive in the first place.
Any ideas? At this point anything to salvage this computer would be helpful.

Spin Cycle,
were those other computers which were able to recognize your SSD in its external enclosure also Macs? Do you know if your SSD has its most recent firmware revision installed? (If it doesn’t, its installer can be downloaded from the Samsung SSD firmware page for burning onto a bootable DVD.) I haven’t used the 830 myself, so I don’t know what its reputation is with Macs. I have an 840 PRO in my MacBook Pro, which has been trouble-free for me, but my understanding is that the 840 EVO has had trouble with Macs in its earlier firmware revisions — so I’m wondering if the 830 has a known track record with Macs, good or bad.

IDM 6.0 Performance Issues - HELP!

Hi,
We have about 11K users in our database(Oracle). We a user tries to execute a workflow from end user menu or it an amdin tries to click on a link e.g. Approvals tab, it often takes over 10 minutes for result page to show up even if there are no items from that users to be displayed.
There are lots of garbage collect activities. GC reaches 500MB to 1GB.
I am looking for some ideas on what I should look for.
I appreciate all responses.

NikhiMahadkar,
the most common performance issues in IDM are:
- Index problems. Your most used search must be indexed. In the configuration object of IDM and the repository database.
- Improper and extensive use of getView/checkin/ckeckout processes.
Some processes like edit, update, change password, etc. get the user view, and when it happens, IDM tries to get all user information in all repositories, so, if one or more of the repositories aren't working fine or there are network latencies, IDM will delay its responses.
Tatiana, if you have 400 repositories for each user, you will wait until the 400 users respond. If you don't want to wait, you should customize the admin interface in order to avoid the checkout process before a page is shown to you.
Hope it helps.

Welcome to the forum.
First thing that I would do would be to look at this Adobe KB Article to see if it helps.
Next, I would try the tips in this ARTICLE.
If that does not help, a Repair Install would definitely be in order.

Anyone using a 12 Core Mac Pro? I have HORRIBLE performance issues .. Help!

After the latest 10.7.4 Mac OS X update I have extremely horrible performance issues with AE ... and they were not so great before the update.
It is still stabilizing ... but an 1:19 clip in SD is taking 12 HOURS TO analyze and stabilize. !!!
The 12 cores are barely being used and this problem has been an issue since I purchased the suite over a year ago.
Does anyone else have problems using AE on their 12 CORE MAC PRO?
REPLY ONLY IF YOU HAVE A 12 CORE MAC PRO PLEASE.
There must be a problem because since the update ... Adobe Encore is PERFECT .. and ALL 12 CORES MAX OUT and the encoding is quick!!
I also have major problems between PP and AE using Dynamic link .. and slow renders in PP.
Everything else works fine .. other apps / other vendors.
I am calling Adobe today.

Thank you for your time.
I am using a 12 Core 2.93 GHZ with 32 GB RAAM and a NVidia GTX 285.

Only half of my hyperthreaded processors are active when using AE "Warp Stabilizer". This issue was addressed before in the Forums. There was no solution. I dont' know if it is any better in CS 6.
Also the automatic saving of all linked compositions while using the dynamic link feature bewteen PP and AE causes huge inoperatable waiting times .. unbearable. My guess is that the new "Global Performance Cache " fixes this ... which I consider update to a terrible problem .. but they sell it as a feature ( Ill go into that later.
Question:
What RAID card are you using?
Do you use the Warp Stabilizer?

Can someone help me diagnose a strange stored procedure performance issue please?

I have a stored procedure (posted below) that returns message recommendations based upon the Yammer Networks you have selected. If I choose one network this query takes less than one second. If I choose another this query takes 9 - 12 seconds.
/****** Object: StoredProcedure [dbo].[MessageView_GetOutOfContextRecommendations_LargeSet] Script Date: 2/18/2015 3:10:35 PM ******/
SET ANSI_NULLS ON

ENDThe Actual Execution Plan Shows up the same; there are more messages on the Network that is slow, 2800 versus 1,500 but the difference is ten times longer on the slow network.Is the fact I am doing a Top 40 what makes it slow? My first guess was to take the Order By Off and that didn't seem to make any difference.The execution plan is below, it takes 62% of the query to look up theIX_Message.Score which is the clustered index, so I thought this would be fast. Also the Clustered Index Seek for the User.UserID take 26%which seems high for what it is doing.
I have indexes on every field that is queried on so I am kind of at a loss as to where to go next.
It just seems strange because it is the same view being queried in both cases.
I tried to run the SQL Server Tuning Wizard but it doesn't run on Azure SQL, and my problem doesn't occur on the data in my local database.
Thanks for any guidance, I know a lot of the slowness is due to the lower tier Azure SQL we are using, many of the performance issues weren't noticed when were on the full SQL Server, but the other networks work extremely fast so it has to be something to
with having more rows.
In case you need the SQL for the View that I am querying it is:
SET QUOTED_IDENTIFIER ON
GO
CREATE VIEW [dbo].[MessageView]
AS
SELECT M.UserID, M.MessageID, M.NetworkID, N.Name AS NetworkName, M.Subjects, M.SubjectsCount, M.RepliesCount, M.LikesCount, M.CreatedDate, M.MessageText, M.HasLinkOrAttachment, M.Score, M.WebUrl AS MessageWebUrl, U.UserName AS PosterUserName,
U.Name AS PosterName, U.FirstName AS PosterFirstName, U.ImageUrl AS PosterImageUrl, U.EmailAddress AS PosterEmailAddress, U.WebUrl AS PosterWebUrl, M.MessageSource, M.ImagePreviewUrl, M.LinkFileName, M.FileDownloadUrl, M.LinkType, M.SmallIconUrl
FROM dbo.Message AS M INNER JOIN
dbo.Network AS N ON M.NetworkID = N.NetworkID INNER JOIN
dbo.[User] AS U ON M.UserID = U.UserID
GO
The Network Table has an Index on Network ID, but it non clustered but I don't think that is the culprit.
Corby

I marked your response as answer because you gave me information I didn't have about the sort. I ended up rewriting the query to be a join instead of the In's and it improved dramatically, about one second on a very minimal Azure SQL database, and before
it was 12 seconds on one network. We didn't notice the problem at all before we moved to Azure SQL, it was about one - three seconds at most.
Here is the updated way that was much more efficient:
CREATE PROCEDURE [dbo].[Procedure Name]
-- Parameters
@UserID int,
@SourceMessageID int = 0
AS
BEGIN
-- variable for @HomeNeworkUserID
Declare @HomeNeworkUserID int
-- Set the HomeNetworkID
Set @HomeNeworkUserID = (Select HomeNetworkUserID From NetworkUser Where UserID = @UserID)
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON
;With cteMessages As
-- Begin Select Statement
Select (Fields List)
-- Join to Network Table
From MessageView mv Inner Join NetworkUser nu on MV.NetworkID = nu.NetworKID -- Only Return Networks This User Has Selected
Where nu.HomeNetworkUserID = @HomeNeworkUserID And AllowRecommendations = 1
-- Do Not Return Any Messages Created By This User
And mv.[UserID] != @UserID
-- Do Not Return The MessageID
And mv.[MessageID] != @SourceMessageID
), cteHistoryForThisUser As
Select MessageID From MessageRecommendationHistory Where UserID = @UserID
-- Begin Select Statement
Select Top 40 (Fields List)
-- Join to Network Table
From cteMessages m Left Outer Join cteHistoryForThisUser h on m.MessageID = h.MessageID
-- Do Not Return Any Items Where User Has Already been shown this Message
Where h.MessageID Is Null
-- An Order By Is Needed To Get The Best Content First
Order By Score Desc
END
GO
The Left Outer Join to test for null was the biggest improvement, but it also helped to join to the NetworkUser table instead of do the In sub query.

Performance issue in DB need help with analysing this ADDM report

Hi,
My environment:
Os: RHEL5U3 / 11.1.0.7 64 bit / R12.1.1 64 bit
Issue:
Few days are am facing serious of performance problem in our Production instance. Normally the issue will occur 5 to 10 minutes occasionally per day. At the time of issue we not able to access the EBS application its taking time to load. But backend all the oracle, listener and apps services are up and running. No locks at table and session level. Cpu and memory usage is normal.
We have monitored using "Enterprise Manager" for this issue and we found the wait session present more in Active session tab. At this time EBS application is not able access its loading too time. After some time the in Active session tab the wait session came normal and when we try to access the EBS application its working fine.
We try to find the cause of the issue by running addm report. But am not able to understand what its says. Kindly suggests me
