EBS 12 - closer to the time it takes to merge of tablespace
Good evening!
Guys, I have detected a hint of fragmentation of 6.58 in a tablespace of our test EBS server.
They asked me to try to recover the disk space, so initially I want to execute a statement "ALTER TABLESPACE COALESCE nom_tablespace" on this tablespace.
This is the scenario:
OS: RHEL 5.7 x86_64
Oracle EBS: 12.1.3
Oracle database: 11.1.0.7.0
Processors: 8
RAM: 16 GB
The memory allocated to Oracle DB: 8GB
Tablespace to coalesce.
Total size: 384GB
Used tablespace space: 372,9 GB
Free space: 11.1 GB
According to your own experience, how long could merge this tablespace? I have to communicate an approximate time of how long the process at the head of our Department before proceeding.
Thanks in advance!
Good afternoon!
Sorry for the absence.
I made a clone of our test EBS server and run the statement "ALTER TABLESPACE nom_tablespace COALESCE", surprisingly the process finished 5-7 seconds later.
Then I read about this behavior, and the answer comes from the Oracle DB documentation:
«Free coalescence extends is not necessary for locally managed tablespaces.»
I questioned the tablespace, it is managed locally. So, for me, it was a good lesson.
After this discovery, I proceeded to reorganize the storage space.
Thanks for your advice!

new Express connects properly to the Time Capsule, takes both in offline mode
I bought an Airport Express to extend the network of my time capsule wireless (2014). Introduction following the instructions as shown in the extend a network , it connects then after seconds seems to knock the time Capsule out of the network Express drops off the power, then the two, this happening again.
I looked online and when a successful network is established a dotted line indicating a wireless connection appears under the time capsule, on mine utility Aiport is implementing a continuous line next to the time Capsule. Hope this has meaning and any help is greatly appreciated.
In general you're doing something wrong... for example... you have ethernet connected between the TC and the Express... and then extend it by wireless... that will do exactly what you live... extend a network can be in wireless or ethernet... What are you doing?
IF in wireless then no ethernet connection...
If by ethernet then you do not extend... you create a network name parameters and security wireless...
All this is supposed to happen automatically but frankly the magic went out on Mavericks and now it's just hard work.

What is the time it takes to run out of memory and cpu between the hypervisor and vm?
I wanted to know the time for the performance of CPU and memory between VMS and the hypervisor. I know that there is a sort of delay when the virtual computer runs cpu or memory because it has transmitted to the hypervisor and handed over to the virtual machine. Thanks for the help.
It depends on the workload and server usage. If the system is not completely loaded and active code is in user space there is zero delay. If the host is used then the virtual machine is provided a slice of time to system resources and will have to wait his turn to access the CPU. In this case, the time is according to the system load.
In short, delay of CPU and memory can be and is often zero.

Isn't time that Microsoft has put some of their skills as computers immediately when starting lit instead of focus on trying to outdo all other systems with stuff
By the way, I have the same comment on the closure, it takes some time to completely close down--another point for Microsoft to put the attentionUnfortunately, the processor is just at the level of the minimum required. In addition, RAM is 4 GB, in which folder page size will be approximately 8 GB. Norton 360 scans all files prior to execution, even if it's a system file. This is the reason for the delay.
Try to upgrade the processor and the rest will be solved. -
reset the timer using a structure of the event
I wrote a simple code to count the second and the timer can be reset if I press the button "reset".
It works; However, there are two problems,
1. when I run the program, the timer takes 1 second to start
2 when I press the reset button, the timer also takes a second to answer
I think it's the 1000ms that is connected to the left corner of the structure of the event. Is there a better way to overcome this problem? (the timer starts and resets immediately
When I launch the program and press the "reset" button)
Thank you!!
Dear ivy037
You can make the time outside the structure of the event as in the attached code. I would like to know if this is satisfactory.
Thank you

How to measure the time elapsed between two steps?

In my script, I ask the subsequences. How can I measure the time it takes each subsequence?
Something like:
Statement: StationGlobals.TimeElapsed = 0
-> SOMETHING HERE TO START A COUNTER<>
call sous-suite
Popup: Str (TimeElapsed)
Thanks for help
StationGlobals.Time = Seconds()
... / / stuff in time
StationGlobals.Time = Seconds() - StationGlobals.Time

What is the time takes to charge iPad air at 100%
What is the time takes to charge iPad air at 100%.
It take me 10 hours to charge the iPad. Kindly update there is no fault on iPad.
It is difficult to know if there is anything wrong with the device, but it's more than twice as long it should take to recharge a weak battery on an iPad. You charge the unit with cable, adapter and plugged into a wall outlet? You use while loading it and if you are, which applications (games) are you running?

I recently dropped my laptop and it is weird, one day he int open up to 4 start times and sometimes it shows me a folder and a question mark in the interface and sometimes asked to reset my password, what are the steps to take?
Anything can be corrupted on your MacBook Pro, but from what you say, it seems that the cable drive/SSD/flash memory/SATA hard was seriously damaged. Him "question mark" means that your Mac is unable to find any bootable device, meaning that it does not yet detect your OS X drive.
You should make a backup of your files (if you can still do it) and take the Mac at the Apple Store or dealer to get a diagnosis. There may be several damaged parts.
