Stream Pool Sizing and SGA AMM
Hi DBAs,
Just a very general question. I have enabled the SGA AMM. So the Stream Pool Size is not defined. Sometime I am getting the warning for messages are spilling over. Should I increase the SGA or Disable the Automatic Memory Managent and define the Stream Pool Size explicitly. I am using Oracle 10.2.0.4 (single instance). I have heard from some experts that SGA AMM feature doesn't scale well some time but not sure how it manage the streams pool. If SGA AMM is not enabled then SGA only allocate 10% for Stream Pool. Total System RAM is 16GB and SGA Max and Target is 8 GB.
Should I increase the SGA AMM enabled or explicitly define the Stream Pool Size? Any suggestion please ..
Regards

When you set SGA_TARGET, normally the value of STREAMS_POOL_SIZE is 0 and AMM allocate memory as needed by the system.
Nevertheless, if you set it, then it means you request the minimum value for streams_pool_size not to shrink below this value.
You did not precise if the spilling occurred on Source or on Target.
-On source, it means that the messages are not propagated fast enough (usually this is paired with flow control in effect) and the excess messages are spilled to disk queue table.
-On Target, it means the apply process is not fast enough, and messages received in the buffered queue table are spilled onto the disk queue table (your aq$_<queue_name>_P)

Data Pump Export issue - no streams pool created and cannot automatically c
I am trying to use data pump on a 10.2.0.1 database that has vlm enabled and getting the following error :

This is my script (that I currently use on other non vlm databases successfully):

this is my parameter file :

My oracle directory is created and the user has rights
googling the issue says that the shared pool is too small or streams_pool_size needs setting. shared_pool_size = 1200M and when I query v$parameter it shows that streams_pool_size = 0
I've tried alter system set streams_pool_size=1M; but I just get :
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-04033: Insufficient memory to grow pool
The server is a windows enterprise box with 16GB ram and VLM enabled, pfile memory parameters listed below:
# resource
processes = 1250
job_queue_processes = 10
open_cursors = 1000 # no overhead if set too high
# sga
shared_pool_size = 1200M
large_pool_size = 150M
java_pool_size = 50M

# System Managed Undo and Rollback Segments
undo_management=AUTO
undo_tablespace=UNDOTBS1
# vlm support
USE_INDIRECT_DATA_BUFFERS = TRUE
DB_BLOCK_BUFFERS = 1500000
Any ideas why I cannot run data pump? I am assuming that I just need to set streams_pool_size but I don't understand why I cannot increase the size of it on this db. It is set to 0 on other databases that work fine and I can set it which is why I am possibly linking the issue to vlm
thanks

Kernel para and sga,pga sizing
Hello,
OS-HP-UX(configured to use high sga /no restrictions)
Current database is running without any issue
Due to increase in physical ram i plan to increase sga and pga(ram is increase about 3 times)
My question:
1)should i also increase sga and pga in same propotion (3 times then existing)
or use 70% ROT formula
2)whatever figure i arrive by analysis for increasing sga,do i need to change kernel parameters also
(does i requre to change kernel parameter every time ram and sga is increased)
Please suggest

Ok some questions based on your reply:
1)then how any gain in upgrading memory above 4 GB if shmmax cannot be more then 4 GB (32 bit OS),then
SGA also cannot be > 4GB (As per documents SHMMAX should be > SGA)Because the SGA doesn't have to be in one segment. Which version of Oracle are you looking at? It makes a difference!

2)I read if Operating system is linux can use SGA above 4GB,in fact one of friend told they implemented SGA
4GB on linux configuring VLM/Huge pages,so in that case ( VLM ) needs to set SHMMAX > 4GB (as per memory ROT) of VLM take cares of SGA > 4GB even if SHMMAX is not setintrestingly my friend also mentioned that in there server VLM is set and shmmax is set < 4 GB and SGA > 4GB
still it works without problem when checking SGA usage in dyanamic views its shown as using above 4 GB
,it contradicts what i read in documents,how this is working ,anyone have idea?[url http://download.oracle.com/docs/cd/B28359_01/server.111/b32009/appi_vlm.htm]No contradiction.
Also VLM implementation is restricted to Linux or it can be on set on Unix as well and if its set do all components
of SGA benefit or only buffer cache?
ThanksIt varies, some unix are quite different than others. Specific answers can only be given to specific configurations. I really have to wonder when you are asking about hp-ux and 32 bit. -

Hi,
I would like to know how to size the initial SGA size while creating the database.
What are the things that we have to consider for sizing the SGA?
If we have to consider if it is OLTP/DSS system, how many concurrent transactions, how many users and all, then provide me a detailed info, like if there are 100 users assign this much space, and so on.
Thank you in advance.
RajeshSee Rajesh, Tuning is not a rocket science, It can not be learned at the rate of knotes. coming back to your question, you assume your database is going to be used for OLTP, well, even that case, there are number of things still matters.
these are...
1. what would be the size of your database ?
2. No of cuncurrent users conneted to oracle database?
3. What are the physcial resources you have (cpu's, memory etc) ?
4. Amount of sorting peromed by each session.
5 Many more ....
But if you really like to make an educative guess, then you can start with optimal values and increase the size according to demand. Yinguan is already suggested you to go through with tuning guide, which is the basic need for that person like to jump into tuning ocean.

Size of Kernel parameter and SGA
Hi,
Can you please suggest me the ideal size of kernel parameters and SGA?
Currently, I have installed 2GB RAM on my machine using Oracle 10.1 database version on Fedora Linux platform. The parameters are currently set as below:
kernel.shmall = 2097152 (2MB)
kernel.shmmax = 2147483648 (2048 MB)

I will appreciate if you can give me an idea about the proper size of SGA including SHARED_POOL_SIZE,LARGE_POOL_SIZE AND JAVA_POOL_SIZE.
Thanks in advance.
JayeshOracle's install docs indicate practical minimums. The specific section for Linux x86 is at
http://download-west.oracle.com/docs/cd/B19306_01/install.102/b15660/pre_install.htm#sthref264
The proper size of the pools is always dependent on the workload. It takes experience, understanding of the application and monitoring to size these properly - the realm of the DBA.
However, by setting the SGA_TARGET to some value (less than equal to SGA_MAX_SIZE) and setting these three parameters to '0', the system will use an effective compromise that dynamically changes based on workload.
My suggestion is that the SGA_TARGET and the PGA_AGGREGATE_TARGET be set to ensure the system does not start swapping - when considering all the other normal memory requirements on the system. -
I'm trying to connect my iPad to my tv so that I can mirror whatever is on my iPad. I want to stream movies online and watch on the tv. I have the digital av adapter and an hdmi cable but it's not working. Any tips ?
If this is an iPad 1, it won't mirror, but it will still output video from the 30 Pin dock connector.
If your new TV has a conventional VGA in and stereo inputs you can try this connector.

I used to stream video from both Netflix and YouTube and from my Mac using iTunes sharing through my iPad then with this connector plug into my iPad and TV.
It won't be high resolution, but it will get you picture from iPad to TV.
Good Luck. -
Print Sizing and Quality Issues
When I print PDF documents I have issues with sizing and quality. I only have this issue with my Mac. Windows prints the files as they should be. I've tried two different printers, both over network. It doesn't matter whether I am in Adobe or in a browser. Basically it oversizes the documents and cuts off the edges. The quality on images and logos is severly degraded. This probelm existed in Lion and now in Mountain Lion. Any help?
What we need are the clip properties & sequence settings in Final Cut Express. Your screenshot is from a Finder window.
It would appear you have a clip with nonstandard frame size (1366x768) in an H.264 file. FCE cannot edit this material. FCE is limited to specific codecs and frame sizes. You need to convert your clip to QuickTime/Apple Intermediate Codec. If it's highdef widescreen then convert it to QT/AIC 1920x1080i. Try using MPEG Streamclip to convert the source clip.
You also need to be using a matching Easy Setup in Final Cut Express. If your source media file is QT/AIC 1920x1080i then you should select the AVCHD Apple Intermediate Codec 1920x1080i60 Easy Setup in FCE -AND- then create a new sequence before importing your clip into FCE and placing it in your sequence (timeline) -
Re-sizing and Pasting in Elements 12
I've just got Elements 12 and I'm having difficulty getting started.
The first thing I need to do, is to re-size a load of images - I need them to be a specific size in centimetres. I don't care how many pixels they are, or how big the file is.
However, whenever i try re-sizing, and then open the image in something else, it hasn't really changed size - it's just set to print at that size in elements. As I'm not printing them, I'm sending them digitally elsewhere to be printed, that's no good to me- is there any way to actually change the size.
Once I've got the images resized, I then want to paste them onto a slightly larger black background. However, I don't seem to be able to paste between files. Is this normal?
To sum up:
I have a load of jpegs and pngs of various sizes, I want to get them all to 6.12 x 8.6 cm, then paste them into a black background 6.4 x 9 cm (providing a thin border against the edges being cropped int he printing process) and save as jpegs. These jpegs will then be uploaded to a printing company via the internet.
I'd hoped this would be a fairly simple process, but it seems to be impossible. Can anyone help?For printing, it desirable to have the resolution in the range 240-300px/in.
You can convert the ruler scale to metric by right clicking on the ruler. This will help you to visualize the dimensions for reference.
On the crop tool's option bar, enter 6.12cm and 8.6cm for w & h (depending on portrait/landscape orientation.) Enter resolution 240px/in in the resolution field.
Drag out the crop shield to embrace what you wish to retain, then commit with the green checkmark.
Set your foreground color chip to black
Go to Select menu>all
Open a blank layer above the background layer
Goto Edit menu>Stroke(outline) selection. Try stroke width 5px, position:inside. OK
Press CTRL+D to get rid of the marching ants.
You can adjust the black border (stroke width) to suit - simply delete the layer created in step #5, and replace it. -
How can I get data in flat file from Pool table and cluster table ?
Hi,
I am working in one Achiving project. My requirement is to get data into flat file from Cluster table and pool table.
Is there any tool avilable to download data into flat file from pool table and cluster table ?
if table name given in the selection screen then data will be downloaded into flat file.
waiting for quick response.
Best Regards,
BansidharData cannot be retrived directly form the cluster table
as the Cluster results are stored in Cluster Key say for example PCLkey
and form that Key we need to fetch the data
these clustes are not the part of PNP or PNPCE tables

how do i get my photos to stream to my iPad in the events that were oringally created. Right now they are streaming as photos and are not grouped at all. I would like to get them back into the events that were originally created
Hi..
Thanks for the reply..
My original I Phone 5 was running IOS 6.12
My I phone 5S currently runs IOS 8..When I upgraded it, it had IOS 7 on it which made the I Photo app compatible with everything below IOS 8...( which the photo app is not compatible with ) so I just connected the I Phone 5S to my computer and thinking the new phone had IOS 7 on it that these was nothing to worry about..I thought all 900 + pictures in the photo stream would transfer but somewhere in the process, I Tunes decides to just go and install IOS 8 which requires that you run a " Photo Migration App" to transfer photos from IOS 7 & below. The problem was is that I didn't want IOS 8 on my new 5S so I thought I wouldn't have to do that part..
Anyway the phone emerged with IOS 8 on it and the only photos that remained were the ones that were actually on the phone..The 900 + I had in the stream didn't transfer because the Photos that works on IOS 7 and below isn't compatible with IOS 8..I guess you have to use the photo migration app that comes with IOS 8 & I phone 6..But I didn't ask to upgrade to IOS 8...It just did it on it's own!
I still have the I Phone 5 Back up that I did just before giving it back to Verizon but if I try to restore the I Phone 5S running IOS 8 those photos in the stream will not go back on the phone because IOS 8 isn't compatible with the I Photos" that ran on IOS 7 and below..
So I have an I Pad mini that runs IOS 7..should I try and erase it...and put that I Phone 5 backup on it and pray the photos that were in the stream come back on it so I can transfer them back to my computer...then erase the I pad mini again and restore it using it's original backup that I have on the computer and the in the cloud?
I know this sounds confusing but I'm at a loss as to what to do..This is what I found ...http://support.apple.com/en-us/HT201386
but it doesn't help me..

I just bought my apple tv yesterday and SET UP THE HOME SHARING ON MY COMPUTER, I CAN STREAM MY PHOTOS AND SEE ALL THE VIDEOS AND LISTEN SONGS IN MY ITUNES, BUT CAN NOT DO HOME SHARING, ON THE TV, ALWAYS SHOWS "TURN ON HOME SHARING ON YOUR OMPUTER WITH YOUR ID WHICH I DID BUT NOTHING HAPPEN. WHAT'S WRONG? WHAT SHALL I DO NOW?
I have found with AppleTV that it is the IPV6 on the computer you want to access is the problem. The issue is that Homegroup on Win 7 or Win 8 requires IPV6 to work, but AppleTV won't work with IPV6. (So maybe double check you have IPV6 turned off)
So you have to make a choice - Homegroup or AppleTV.... but you can't have both, until Apple brings ATV up to date. (crazy that it does not recognise IPV6 - c'mon Apple!)
You can set up sharing individually in Win 7 or 8 and have the ATV access files that way.
Having said that, there is always the exception.. I have an old HP home server running Win8 and it services ATV - but is part of the Homegroup... have no idea why it works on both, but no other machine on the home network will talk to both ATV and Homegroup at the same time! -

Questions regarding risk register, resource pool, reports and KPI
I am going on a requirement gathering activity today about a new MS Project Server project. I have knowledge of SharePoint but my knowledge of Project Server is very limited. Following will be my topic of discussion with client. Can you please tell me what
kind of questions can I ask about them? I want to gather as much requirement as possible from client.
Some of the question I can think of are:
1. What fields will be there in each register?
2. What kind of permission do you want on each register? For e.g. will each register will be publicly viewable to all users or not?
3. How many KPIs and Dashboards do you need?
Topics
• Project Register
• Issue Register
• Risk Register
• Decision Register
• Invoice Register
• Change Request Register
• Deliverable Register
• Resource Pool
• Reports and KPIsAs You know Project Server sits on SharePoint. If you know which version of Project server your client want.
Then you can ask some question(I am giving you list of few question) like:
1. Approx No of users
group and security related questions like which kind of permission they want for Project manager, team member, resource manager etc.
2 Approx no of Project per year
3. Avg no of task per project
4. Project level Custom field
5. Task level Custom Field
6. Resource Level Custom field
7. Project, resource or task level of custom view
8. Any demand Management workflow
9. back up and restore strategy.
10. any Issue or risk associated with project and mitigation plans
11. drivers or strategy for Portfolio management
12. If any change need to be done in EPM environment how you guys can handle it.
13. for Delivery you can split your project in phases in which first phase will contain installation and basic configuration then report development, then Custom development, then Training and support
14. which kind of report they want (SSRS, Excel baed, Performance point, dashboard, Power pivot)
15. for reports what would be the KPI
16. Tracking method, Timsheet usage, status Reports
17. whether they will use default Project site or customized project site
18. Enterprise Project template for Business unit.
19. Department specific reports.
20 .for infra you can ask (Redundancy, server performance high availability )
etc.
Please group all these as per our need.

Exporting photos for UHDTV or Native 4K TV, what are the best settings ? (File: Quality File: Color Space, Image Sizing and resolution) Or in other words; How can I get the smallest files but keep good quality for display on new UHDTV
You're welcome, and thank you for the reply.
2) Yesterday I made the subclips with the In-Out Points and Command-U, the benefit is that I've seen the clip before naming it. Now I'm using markers, it's benefit is that I can write comment and (the later) clip name at once, the drawback is that I have to view to the next shot's beginning before knowing what the shot contains.
But now I found out that I can reconnect my clips independently to the format I converted the master clip to. I reconnected the media to the original AVI file and it worked, too! The more I work with, the more I'm sold on it... - although it doesn't seem to be able to read and use the date information within the DV AVI.
1) Ok, I tried something similar within FCE. Just worked, but the file size still remains. Which codec settings should I use? Is the export to DV in MOV with a quality of 75% acceptable for both file size and quality? Or would be encoding as H.264 with best quality an option for archiving, knowing that I have to convert it back to DV if I (maybe) wan't to use it for editing later? Or anything else?
Thank's in advance again,
André
