Total User IO in Mega Bytes
Hi
I wanted to monitor the Total User IO on the database. I mean total Mega Bytes of data written to or read from the database from a particular client.
Please give some pointer if i can achieve this.
thank you
Hi,
You can use AWR for this purpose, only if you are on Oracle 10g or 11g

How to Know total users in Portal
Hi,
How to know the total users in Portal.I gone to User Administraion and tried to search in that with out any parameter then I got a message like "Last search Exceeded the size limit of the Server.Search result is incomplete." and "Last search returned with 1000 elements.". But I want to know the TOTAL USERS in the PORTAL.
Can u help me in this regard. Urgent.
Regards
KrishnaHi Krishna,
the paged search is possible by using the
parameter "ume.ldap.access.extended_search_size" in your configuration XML.
Just set a value blow 1000 e.g. 900 as like in this
example and all entries above 900 will be paged:
<ume.ldap.access.extended_search_size>900</ume.ldap.access.extended_search_size>
Do not forget to restart and check the values "Max. Search" and "Warn. Search" set for the Admin-UI.

List the total users connected at point of time (portal admin)
Hi Dev2Dev team
Is there any way to get List of total users as well as specific users connected to portal at point of time
is there any way to get the list from portal admin
or from weblogic server
is there any tool available for this
can anyone provide me with the sample or code or tool
Thanks
SuryaHi All
Is that the data's of login and logout details are stored in Pointbase db by default.
I am using oracle where i have all my default portal tables.
any info appreciated
Thanks

Hey Guys,
I have a question regarding the total user for Apple Apps.
Based on my finding, I found out that the integration framework where we the username and password in order to use the apps, only accept single user.
Is it possible to use the apps for different user login at the same time?
Please correct me if any wrong statement.
Thank you.
Regards,
Wai LengHey guys,
We have to set the user ID and password in integration framework before we can login right. The steps as below:
Integration Framework -> SLD -> B1iServer -> DBName -> Connectivity List -> B1DI
This is what I did. It allows only one username and password to be entered in. So how to connect with different user account?
Thanks and Regards,

30 minutes of music 300 Mega Bytes?
Hi...I just recorded 30 minutes of music from my keyboard in Garage Band and I was really surprised to see the file 300 Mega Bytes...According to my calculations it should not be any bigger than 30 MB. And then when I wanted to listen to it in Garage Band I kept on getting messages that " Part of the song can not be played....", I guess because it is such a big file and the song would not play properly...Does anyone have an idea? Thanks...
I am talking about the GB file itself
Than, as posted, the size is about right (inside the GB file is an AIFF file, so the 10MB/Min applies)
So should I use a MIDI controller/interface of some sort?
Only if you want to record MIDI.
I can compress the file in the "Save As" option but from what I have read it will alter the quality
Correct. -
Total users active, last login, inactive etc
Hi,

How to limit total user's traffic?
Hello.
How can I limit user's traffic? Access policy has only "object max size".tseyitlin,
Currently the WSA does not support bandwidth throttling. I do not have an ETA for this feature, but I do know it is on the roadmap. Please be in contact with your Sales rep in regards to this feature. -
Hi I am working on a project where we recently have purchased the PXI chassis with several 6555 cards. The technical support gal, although she was very nice, did not know the gory detail of some of the questions I have, so I am hoping someone on the forums here has run into these or would know who to ask.
The specs for the NI PIXe-6555 card claim 8 MB per channel.
* Is it really 8 MB per the 24 DIO channels (so 192 MB total)?
* Is this mega BYTES or BITS?
* If I have a large dataset that is more than 8 MB, is there a way to pre-load or something so that there is not a break in the datastream?
* If we have four of the 6555 cards in one chassis, how close (what is the tolerance or slop) can I get the data streams to be synch'ed at the max speed (200 MHz)?
* If I am driving data at 5V logic levels on our DUT (device under test), can I get the full 200 MHz speed? I am seeing conflicting info on this in the help files.
Thanks!
EdHi Ed,
Hopefully this clears up confusion about how to write data to the generation session of an HSDIO board: How to Write Serial Data for Any Channel on a High Speed Digital I/O Board
If your data width is 1 byte, each bit corresponds to each lane. so 0000 0000 in your byte is a single sample bit for channels 0-7. To write data to independent streams at the same time, you'll have to combine the streams into the U8/16/32 format. For instance, two data lines toggling out of phase with each other on channel 0 and channel 7 looks like so:
Sample 0: 1000 0000
Sample 1: 0000 0001
Sample 2: 1000 0000
Sample 3 :0000 0001
serialized for ch 0: 0101
serialized for ch 7: 1010
If you want to drive only those two channels, while doing other independant operations on channels 1 through 6, you simply only include ch 0, 7 in your Channel List for the Generation Session through the HSDIO driver. By default, the channels not included in the channel list for generation will have their drivers disabled, and can be used for acquisition.
The memory issue here is that for generation, you still have to populate channels that are unused for generation based on the data width. Writing to two channels takes 2 bytes per sample in the above example since U16 (Data Width = 2) is the smallest for the board. This is less than if the samples were 4 bytes wide (U32, Data Width = 4), which takes double the amount of space in memory.
This KB is slightly outdated at the time of posting this, but it explains more about optimizing memory usage with HSDIO and Data Width. Ignore the 655x statements, as 655x only referred to 6551/2 boards at that time. HSDIO Data Width and Memory Allocation
So in summary, it does bitmask based on the channel list into the generation session. It also writes one word (U8/16/32) at a time, for the channels that are enabled for generation, and this does take up memory space on the onboard memory. For your case, to write 11 outputs will require a U16 at least, which is smaller than the default U32, so I would recommend changing data width to 2 for acquisition and generation to obtain the maximum amount of memory available on your device.

Security about SYSTEM and SYS users
Guys,
Just curiosity,
1) What happens if I logged with a user that have DBA role or DROP USER privilege and to drop the SYSTEM or SYS user ? This is possible ? If yes, how can protect them ?
2) I know that the SYS is owner of the dictionary and catalog, but what is the objective of the SYSTEM user to exists ?
Tank you.Hi,
As you say, SYS is the owner of the database and the owner of the data dictionary.
But SYS has the SYSDBA privilege which SYSTEM doesn't. This makes it possible for SYS to become a very very powerful user. In addition, never ever create objects in the SYS schema. SYSTEM is a privileged administration user, and typically owns Oracle provided tables other than the dictionary.
Making a test.

From no sign of 64-bit in the product banner plus VA (address space) 2 GB (close enough), it looks like the server is running as 32-bit process.
With SGA + PGA (target) adding up to nearly 1900 MB, my guess is you are hitting the 2 GB per process limit.
Lower SGA, it should help in the very short term. For longer term: lower resource demands or start planning for migration to 64-bit. -
Oracle 10g - Database does not respond to the application users
Hi all,
I am using ORACLE 10g database with 75 users connections 50 local and 20 remote users using ADSL and dial up modem. Operating system on server is
Windows 2003.
All of a sudden users making the entry get disconnected getting the error as
ORA-12516: TNS:listener could not find available handler with matching protocol stack
Other case users when using the appliaction get their PC hanged and connection
to oracle fails again. they cannot login to the application that time, the error is
ORA-04031: unable to allocate %s bytes of shared memory ("%s","%s","%s","%s")
Twice a day the users trying to login cannot access the database server.
Front end application is in VB using exe file. When the users cannot logon
to the database. I manually stop the ORACLE services(including DB console) and
then stop the listener.
This practice is going on since last two months.
Server Scenario
After Installing Oracle Standard Edition 10g.
System tablespace utilization is 98.5% which is 465 MB out of total 470 MB.
There is only one Rollback Segment named as SYSTEM.
when we install 9i 4 rollback segments as RO1, RO2, RO3, RO4 are created
by default.
Do I need to add the datafile to SYSTEM table space as its current usage is 99.15% and its auto extend is ticked on using auto extent as 10 MB. I tried adding another datafile during weekend downtime. when I resumed on saturday morning I found it did not add any datafile which I had put on thursday eveninig as system02.dbf.
Do I need to add a new datafile to the SYSTEM tablespace ?
Do I need to create new rollback segments apart from SYSTEM rollback segment ?
My current schema size 15360Mb with its usage as 9.32% (1432.25 Mb).

How to calculate bytes received
Hai
i am transferring files in rmi by reading it contents & send it as argument to server. In this i want to find amount of bytes received by server for a file how to find this plz help me
Thanks in advanceFrom what I see, I assume that the client is making a block transfer request, and the server is responding with a byte array.
o The simplest way to figure out the total length of the file - up front - would be to have the file transfer start with some kind of "open" (RMI) message, and have that request receive the total file size as a return value.
o The user can total the length from each byte array, and that is how much FILE data he has received. -

SSMI am hoping your Oracle Consultant know what he's talking about.
According to Oracle Performance Guide,
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14211/memory.htm#sthref654
"On most systems, sizing the log buffer larger than 1M does not provide any performance benefit. Increasing the log buffer size does not have any negative implications on performance or recoverability. It merely uses extra memory.
The best method to determine if bigger redo buffer is needed is
SELECT NAME, VALUE
FROM V$SYSSTAT
WHERE NAME = 'redo buffer allocation retries';
The value of redo buffer allocation retries should be near zero over an interval. If this value increments consistently, then processes have had to wait for space in the redo log buffer. The wait can be caused by the log buffer being too small or by checkpointing. Increase the size of the redo log buffer, if necessary, by changing the value of the initialization parameter LOG_BUFFER. The value of this parameter is expressed in bytes. Alternatively, improve the checkpointing or archiving process.
Other than that, hight log file sync event indicate you need faster disk for your redo logfiles. However, please also post your commits per second and redo per second from your AWR report.
100M redo logs might be small for your environment. -
How to know the no. of bytes in a String Control Function?
Hi,
I would like to know the no. of bytes for a certain String Control Data.
For instance, if i have a String Length Function, on the left is a String Control and on the right is a Length Indicator.
If i will type coordinates, i.e. 9.25,4.25 on the String Control it will show 9 on the Length Indicator. I think 9 do not mean 9 bytes but
only a length. Is there any function in LV that will tell me the total bytes of the data on the string control?
Appreciate for any advise.
Thanks a lot.Thanks tst for your kind reply.
Here is what i am trying to find/goal.
I will be using wireless receiver for my system. The wireless receiver have some signal strength ranges; 95dbm @ 1Mbps (mega bit per sec), 90dbm @ 11Mbps, 82 dbm @ 24 Mbps and 75dbm @ 54 Mbps. Ofcourse i prefer to have lower data transfer rate so that my signal strength is best.
I will be sending coordinate data/s via wireless communication using string controls. But i do not know how big/heavy is my coordinate data
If i can know how many bytes or mega bytes the data i want to send then i will be able to transfer it to bits or mega bits(8 bits = 1 byte) thus i will know which setting i can use for the wireless receiver. And if the data is too big then i have a basis to redesign my data transfer to suite a better signal strength.
Thanks for your help.
