rm -f /tmp/exp_pipe_full_senc1
/usr/sbin/mknod /tmp/exp_pipe_full_senc1 p
nohup compress < /tmp/exp_pipe_full_senc1 > /backup/database/exp_SENC1_"$DT".dmp.Z &
nohup $ORACLE_HOME/bin/exp username/password@senc1 file=/tmp/exp_pipe_full_senc1 log=/backup/database/exp_SENC1_"$DT".log grants=none statistics=none &It exports and compresses immediately.works fine in our environment

Running export in background

Hi,
I need to run my database export in background mode! Could someone please help me with the command?
I guess we can use 'nohup' or '&' to run the exp in background.
But I am not completely sure. Could someone please help me out with the steps.
nohup exp file=exp_xxxxxxxxx.dmp log=exp_xxxxxxxxxx.log direct=y consistent=y compress=y buffer=10000000 owner =xxxx
OR
exp file=exp_xxxxxxxxx.dmp log=exp_xxxxxxxxxx.log direct=y consistent=y compress=y buffer=10000000 owner =xxxx &
Thanks!

Dear user9104898,
nohup means no hang up so if you specify this command before the exp, even you logoff from the unix your command will not stop and will continue.
If you specify nohup and & (at the end) that means no hang up and run the complete command as a background job. So it will run at background and you may leave the system afterwards if you wish.
So yes, you may use both of them, which is even better to do it.
Hope it helps,
Ogan

Page breaks appear in the spool output of report when run in the background

Hi All,
Report is using fm 'REUSE_ALV_GRID_DISPLAY' to display the report. parameters passed to this fm for display are :it_fieldcat,is_layout,it_events,t_outtab.
Page breaks appear in the spool output when report is run in the background.These page breaks needs to be removed. When executed in the background, the excel extract should be the same as if pulling directly from the report itself.
How to remove the page breaks in background?
Thanks & Regards,
Abhishek Singh

Hi
You can use the below code , which the reprt run in background. If you run the report in background thenyou need to use 'REUSE_ALV_LIST_DISPLAY'
if sy-batch = ' '.
call 'REUSE_ALV_GRID_DISPLAY'.
else.
call 'REUSE_ALV_LIST_DISPLAY'.
endif.
if you are using OO alv then write this code..
CALL METHOD cl_gui_alv_grid=>offline
RECEIVING e_offline = off.
IF off IS INITIAL.
CREATE OBJECT g_custom_container
EXPORTING container_name = g_container.
ENDIF.

Export in background mode

Does anyone know how to run an export in background mode for windows ?
Normally in unix I would simply nohup the expdp command.
Also what is the purpose of being able to reattach to a job in Data Pump - that in itself would suggest the export is already running as a background process - so what does this mean for the command prompt window where you launch expdp from ? Can you break out of this command prompt and the export will continue in the background ?
Also is there anyway to monitor how far your export has gone ? At the moment all I am looking at is the contents of dba_datapump_jobs which simply tells me if the job is still executing or not
thanks,
Jim

Jim,
Export does run in a background process. There are actually at least 3 processes running.
1. You have the client, which is where you run your expdp/impdp command.
2. You have the MCP processes which is a Data Pump process
3. You have a WORKER processes (or more if you use parallel) that are Data Pump processes.
I always use LINUX, but I think it works the same for Windows. Once you have the job running, you can type a CTL-C and you will get to an IMPDP> or EXPDP> prompt. This allows you to do other commands. One is to exit the client process. You can also stop the job or kill the job. Try it and type HELP at one of those prompts.
At this same prompt, you can type STATUS will will give you some idea on what is being worked on.
Some of the reasons you would want to attach to a job is
1. You previously exited and want to reattach to change something.
2. You left it running while you were in the office and now you are home and want to see the status. (you can have multiple clients attached to the same data pump job.
3. Your job stopped for some reason (power outage, failure, etc.) and you want to restart it.
Hope this helps.

Read the names of the files in ABAP program that runs in the background

Hello,
I have a program that uploads information from file on application server.
What I can't figure still is how to get the <b>names </b>of the files that are in <b>specific directory</b>.
There is an other application that will post those files into this directory. I wont to get file names and file types from this directory and put it into an internal table.
File names are changing based on date and version.
Please keep in mind that the program runs in the background, (presentation server is not included in the process)
Thanks in advance,

Send/export the background job spool in Excel (in MHTML format) in ECC 6.0.

Hello All,
I have a requirement to send/export the background job spool in Excel (in MHTML format) in ECC 6.0. Please help.
Thank you.
Nalini

Hi Jigar,
Thanks for your response.
Anything is like download to desktop or email is fine. But in MHTML format.
We can download the ALV report in MHTML spreadsheet format when we run the program online. But the program is running for long time and going to dump.
So i scheduled it as background job and downloading the output in .HTML format. But user wants the spool/report output in .MHTML spreadsheet format.
I can write the code. Instead of changing the existing program I would like to know is there any way (from standard SAP) that I can get the background spool in MHTML spreadsheet format.
Thanks,
Nalini

How do I find out what applications are running in the background

I have a 2008 iMac with 2GB memory. How do I find out what programs are running in the background? I am going to buy a new iMac before the end of the year to replace this one. When I looked at Activity Monitor it shows 1.8Gb used but doesn't tell all the programs running.

open activity monitor [if it doesnt launch click winders>Activity Monitor]. then it'll show all proceses

When I click on a new link, it opens a whole new firefox instead of using my default which is running in the background

I have firefox as my default browser. Anytime I click on an email or search for something, instead of opening my default browser, firefox loads a new firefox page. It is a blank page just as if I had never had one. It has nothing on it except how you would start out before you set up your tabs and history etc. My default firefox is still there running in the background but I must click on it and manually put in the link I was trying to open.
Any suggestions.

Some added toolbar and anti-virus add-ons are known to cause
Firefox issues. '''Disable All of them.'''
Start '''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Firefox in Safe Mode]''' {web Link} by holding down the '''<Shift ''(Mac Options)'' >''' key, and then starting Firefox. Is the problem still there?

Can the width of a report that has been run in the background be increased?

Hello Experts,
How can I increase the width of a report that I have run in the background so that it does not wrap text to the next line?
I have been running the same HR report successfully in the background for many months. Today I ran it with the same parameters that I've always used and when I retrieve it from my Own Job Spool - System | Own Spool Request | Display Contents the last field is wrapped to the next line.
Thanks.
Regards,
Jeanette

Jeanette,
Thereu2019s another possibility if Tedu2019s suggestion doesnu2019t work. When you look at your spool requests, thereu2019s an icon on the toolbar next to the eyeglasses that looks like a yellow rectangular callout. Itu2019s called u201CDisplay in Maximum Widthu201D. Select the Spool no. to display and then press this icon. Shift + F4 is the shortcut.

The figures you mention only make sense on your intranet. Are you still using the same wireless router. The verizon one is somewhat limited as far as max wireless-n performace. For one thing it only has a 2.4 radio. I like many people who wanted wireless-n performance before they even added a wireless-n gigabit router, have my own handling my wireless-n network.
