Oracle DB backup script not running - database

I am trying to make a backup using crontab on a linux machine.
I have a short script :
#!/bin/bash
export ORACLE_HOME=<oracle_home_directory>
DATE=`date +%F_%H-%M-%S`
echo $DATE
/u01/app/oracle/product/11.2.0/dbhome_1/bin/expdp system/oramanager full=Y parallel=4 directory=data_pump_dir dumpfile=prod1-ecmdb1-$DATE.dmp logfile=prod-ecmdb1-$DATE.log compression=all
I have placed this script in crontab as such:
02 17 * * * cd /u01/app/oracle/admin/ecmdb1/dpdump/ && /u01/app/oracle/admin/ecmdb1/dpdump/backup.sh > /tmp/test.out
But the script does not run. It says in logs that :
UDE-12162: operation generated ORACLE error 12162
ORA-12162: TNS:net service name is incorrectly specified
If I run the whole script line manually, it works fine. But doesnt work fine using cron. Do I need to setup variables ?

Set ORACLE_HOME AND ORACLE_SID
export ORACLE_HOME=/u01/oracle/product/......
export ORACLE_SID=dbname

Add export ORACLE_SID=<...>
And make sure the cron is set up under the same user, not root.

Here's the working script, after using all the help from Community.
Create a Bash file(used nano here):
nano DBBackUp.sh
Copy the below code and edit the contents in angle brackets:
#!/bin/bash
export ORACLE_HOME=<OracleHomeDirectory>
export ORACLE_SID=<SID>
DATE=`date +%d%m%Y`
DATETIME=`date +%F_%H%M%S`
echo $DATETIME | tee DBBackUp_$DATE.log
echo "Exporting..." | tee -a DBBackUp_$DATE.log
$ORACLE_HOME/bin/expdp <SCHEMA/PASSWORD> directory=DP dumpfile=BACKUP$DATE.dmp | echo export.log | cat export.log >> DBBackUp_$DATE.log
echo "Compressing..." | tee -a DBBackUp_$DATE.log
zip BACKUP$DATE.zip BACKUP$DATE.dmp >> DBBackUp_$DATE.log
echo "Deleting..." | tee -a DBBackUp_$DATE.log
rm BACKUP$DATE.dmp 2>&1 | tee -a DBBackUp_$DATE.log | cat DBBackUp_$DATE.log
Create a cronjob:
00 13 28 04 * /home/oracle/DBBackUp/DBBackUp.sh
Above cronjob executed at 01:00pm on 28th April 2020
System creates export.log in DP directory.
Here, all the files are in same location. [DP Directory]
Make sure that oracle user's having necessary permissions & ownership to the shell script.

How to call ./snowsql file from a bash script on Mac?

I am trying to make a connection from a bash script, accomplishing something similar to this:
rmcguigan$ snowsql --filename test.sql
* SnowSQL * v1.1.86
Type SQL statements or !help
+----------------+
| GREATEST(1, 2) |
|----------------|
| 2 |
+----------------+
1 Row(s) produced. Time Elapsed: 0.108s
So I am running a bash file with chmod 755
>./test.sh
This is the contents of the file
./snowsql test.sql
syslog -s -l "Good to go"
results
rmcguigan$ ./test.sh ./test.sh: line 3: ./snowsql: No such file or
directory Unknown level: Good to go
How should my bash script call ./snowsql test.sql ?
It looks like the problem is that you have ./snowsql test.sql in your test.sh file, which tries to find and execute a file named snowsql in the current directory rather than running the command with that name. Try removing the ./ and using the --filename argument so that the file looks like this:
snowsql --filename test.sql
Make sure that you have a file named test.sql in your current directory as well with whatever SQL statement you want to execute.

Create a bat file for git-bash script

Hi all. I gave a git-bash installed and want some automatisation. I've got a .bat file, which I want to run as
some.bat param | iconv -cp1251 > l.log | tail -f l.log
And I want to run it not in WinCMD but in git-bash shell - tell me plz how to do it?
Git bash on windows uses BASH. You can use bash to create a quick script that can take in parameters and echo them so that you can pipe them to your next utility.
It could look something like this
File: some.sh
#!/bin/bash
#Lots of fun bash scripting here...
echo $1
# $1 here is the first parameter sent to this script.
# $2 is the second... etc. $0 is the script name
then by setting some.sh as executable
$ chmod +x some.sh
You'll then be able to execute it in the git-bash shell
./some.sh param | cat ... etc | etc...
You can read about bash programming
I'd reccomend looking at some bash scripting tutorials such as this one

Substitute user mid-Bash-script & continue running commands (Mac OSX)

I'm building two scripts which combined will fully uninstall a program (Microsoft Lync) on Mac OS X. I need to be able to swap from an account with root access (this account initially executes the first script) to the user whom is currently logged in.
This is necessary because the second script needs to be executed not only by the logged-in user, but from said user's shell. The two scripts are name Uninstall1.sh and Uninstall2.sh in this example.
Uninstall1.sh (executed by root user):
#!/bin/bash
#commands ran by root user
function rootCMDs () {
pkill Lync
rm -rf /Applications/Microsoft\ Lync.app
killall cfprefsd
swapUser
}
function swapUser () {
currentUser=$(who | grep console | grep -v _mbsetupuser | grep -v root | awk '{print $1}' | head -n 1)
cp /<directory>/Uninstall2.sh${currentUser}
su -l ${currentUser} -c "<directory>/{currentUser}/testScript.sh";
<directory> actually declared in the scripts, but for the sake of privacy I've excluded it.
In the above script, I run some basic commands as the root user to remove the app to the trash, and kill cfprefsd to prevent having to reboot the machine. I then call the swapUser function, which dynamically identifies the current user account signed into and assigns this to the variable currentUser (in this case within our environment, it's safe to assume only one user is logged into the computer at a time). I'm not sure whether or not I'll need the cp directory/Uninstall2.sh portion yet, but this is intended to solve a different problem.
The main problem is getting the script to properly handle the su command. I use the -l flag to simulate a user login, which is necessary because this not only substitutes to the user account which is logged into, but it launches a new shell as said user. I need to use -l because OS X doesn't allow modifying another user's keychain from an admin account (the admin account in question has root access, but isn't nor does it switch to root). -c is intended to execute the copied script, which is as follows:
Uninstall2.sh (needs to be executed by the locally logged-in user):
#!/bin/bash
function rmFiles () {
# rm -rf commands
# rm -rf commands
certHandler1
}
function certHandler1 () {
myCert=($(security dump-keychain | grep <string> | grep alis | sed -e 's/"alis"<blob>="//' | sed -e 's/"//'))
cLen=${#myCert[#]} # Count the amount of items in the array; there are usually duplicates
for ((i = 0;
i < ${cLen};
i++));
do security delete-certificate -c ${myCert[$i]};
done
certHandler2
}
function certHandler2 () {
# Derive the name of, and delete Keychain items related to Microsoft Lync.
myAccount=$(security dump-keychain | grep KeyContainer | grep acct | sed -e 's/"acct"<blob>="//' | sed -e 's/"//')
security delete-generic-password -a ${myAccount}
lyncPW=$(security dump-keychain | grep Microsoft\ Lync | sed -e 's/<blob>="//' | awk '{print $2, $3}' | sed -e 's/"//')
security delete-generic-password -l "${lyncPW}"
}
rmFiles
In the above script, rmFiles kicks the script off by removing some files and directories from the user's ~/Library directory. This works without a problem, assuming the su from Uninstall1.sh properly executes this second script using the local user's shell.
I then use security dump-keychain to dump the local user's shell, find a specific certificate, then assign all results to the cLen array (because there may be duplicates of this item in a user's keychain). Each item in the array is then deleted, after which a few more keychain items are dynamically found and deleted.
What I've been finding is that the first script will either properly su to the logged-in user which it finds, at which point the second script doesn't run at all. Or, the second script is ran as the root user and thus doesn't properly delete the keychain items from the logged-in user it's supposed to su to.
Sorry for the long post, thanks for reading, and I look forward to some light shed on this situation!
Revision
I managed to find a way to achieve all that I am trying to do in a single bash script, rather than two. I did this by having the main script create another bash script in /tmp, then executing that as the local user. I'll provide it below to help anybody else whom may need this functionality:

function certHandler1 () {
# Replace 'PRIVATE_STRING' with whatever you're searching for in Keychain
myCert=($(security dump-keychain | grep PRIVATE_STRING | grep alis | sed -e 's/"alis"<blob>="//' | sed -e 's/"//'))

mysqldump puts CREATE on the first line with mysqldump

Here's my full bash script:
#!/bin/bash
logs="$HOME/sitedb_backups/log"
mysql_user="user"
mysql_password="pass"
mysql=/usr/bin/mysql
mysqldump=/usr/bin/mysqldump
tbackups="$HOME/sitedb_backups/today"
ybackups="$HOME/sitedb_backups/yesterday"
echo "`date`" > $logs/backups.log
rm $ybackups/* >> $logs/backups.log
mv $tbackups/* $ybackups/ >> $logs/backups.log
databases=`$mysql --user=$mysql_user -p$mysql_password -e "SHOW DATABASES;" | grep -Ev "(Database|information_schema)"`
for db in $databases ; do
$mysqldump --force --opt --user=$mysql_user -p$mysql_password --databases $db | gzip > "$tbackups/$db.gz"
echo -e "\r\nBackup of $db successfull" >> $logs/backups.log
done

exit 0
Problem is when i try to import it with mysql i am gettint error 1044 error connecting to oldname_db. When i opened sql file i have noticed on the first line CREATE command so it tries to create that database with the old name. How can i solve that problem?
SOLVED.
Using --databases parameter in my case is not necessary and because of --databases it was generating CREATE and USE action in the beginning of the sql file, hope it helps somebody else.
Use the --no-create-db option of mysqldump.
From man mysqldump:
--no-create-db, -n
This option suppresses the CREATE DATABASE statements that are
otherwise included in the output if the --databases or --all-databases
option is given.

copy db file with adb pull results in 'permission denied' error

I just rooted my Nexus 5 using this method: http://www.phonearena.com/news/How-to-root-Google-Nexus-5_id49014
I also enabled USB debugging in the developer options.
Then I tried to pull a database file from my device using this command:
adb pull /data/data/path.to.package/databases/data /sdcard/test
I get permission denied error.
I don't have the debugged flag set in that app I tried to access. Is that the reason I can't access that file? If yes, are there any workarounds to access an apps files?
You can use run-as shell command to access private application data.
If you only want to copy database you can use this snippet, provided in
https://stackoverflow.com/a/31504263/998157
adb -d shell "run-as com.example.test cat /data/data/com.example.test/databases/data.db" > data.db
I had the same problem. My work around is to use adb shell and su. Next, copy the file to /sdcard/Download
Then, I can use adb pull to get the file.
Did you try adb remount after giving adb root?
This generic solution should work on all rooted devices:
adb shell "su -c cat /data/data/com.android.providers.contacts/databases/contacts2.db" > contacts2.d
The command connects as shell, then executes cat as root and collects the output into a local file.
In opposite to #guest-418 s solution, one does not have to dig for the user in question.
Plus If you get greedy and want all the db's at once (eg. for backup)
for i in `adb shell "su -c find /data -name '*.db'"`; do
mkdir -p ".`dirname $i`"
adb shell "su -c cat $i" > ".$i"
done
This adds a mysteryous question mark to the end of the filename, but it is still readable.
If you get could not copy and permissions are right disable selinux.
Check if selinux is enabled.
$ adb shell
$su
# getenforce
Enforcing
Selinux is enabled and blocking/enforcing.
Disable selinux
# setenforce 0
do your stuff and set selinux to enforcing.
# setenforce 1
I had just the same problem, here's how to deal with it:
adb shell to the device
su
ls -l and check current access rights on the file you need. You'll need that later.
go to the file needed and: chmod 777 file.ext. Note: now you have a temporary security issue. You've just allowed all the rights to everyone! Consider adding just R for users.
open another console and: adb pull /path/to/file.ext c:\pc\path\to\file.exe
Important: after you're done, revert the access rights back to the previous value (point 3)
Someone mentioned something similar earlier.
Thanks for the comments below.
This answer ended up working for me: https://stackoverflow.com/a/15559278/53001
Backup to a file, pull the backup, and then convert it to a tarball and extract it.
adb backup -f myAndroidBackup.ab com.corp.appName
dd if=myAndroidBackup.ab bs=1 skip=24 | python -c "import zlib,sys;sys.stdout.write(zlib.decompress(sys.stdin.read()))" | tar -xvf -
$ adb shell
$su
# getenforce
Enforcing
now try
adb shell
su
chmod 777 /path/to/yout_file
exit from shell
open new CMD and try adb pull /path/to/yout_file
It will work fine now.
you'll have security problems because of this any application will be able to access your database.
#guest-418 tips works well:
adb -d shell "run-as com.example.test cat /data/data/com.example.test/databases/data.db" > data.db
However, if you want to use a GUI, use Android Studio's Device File Explorer.
Launch Android Studio
Click on Device File Explorer at bottom right-side
Navigate to your app's file:
/data/data/path.to.package/databases/data
Right-mouse click select Save As and save to a local folder
I have been having Android Monitor hang on me lately on macOS. Device File Explorer works well for this purpose.
Create a folder in sdcard :
adb shell "su 0 mkdir /sdcard/com.test"
Move your files to the new folder :
adb shell "su 0 mv -F /data/data/com.test/files/ /sdcard/com.test/"
You can now use adb pull :
adb pull /sdcard/com.test
When executing adb commands, by default, a limited privileges user is used, the same kind of limited privilege user that is assigned to an app, and you have requested for all privelages to use all features of the device.
This kind of limited user helps protect your phone from malware, by restricting the access between apps, and the system. This is the reason you are unable to access app data and system data on an unrooted phone. The act of rooting means becoming user 0, the super user of the system, capable of any action, and is the highest privilege. Your apps however, are still secure in that they can not talk to eachother.
Now when accessing secure files, note that you do not want to change the permissions of the file when you access it, which may allow for vulnerabilities.
An option that you could use instead, is to make a copy of the file on the sdcard as root, modify that as a standard user, and then move it back into the filesystem as root, while preserving the file permissions of the original file.
Since I've updated to Android Oreo, I had to use this script to fix 'permission denied' issue.
This script on Mac OS X will copy your db file to Desktop. Just change it to match your ADB_PATH, DESTINATION_PATH and PACKAGE NAME.
#!/bin/sh
ADB_PATH="/Users/xyz/Library/Android/sdk/platform-tools"
PACKAGE_NAME="com.example.android"
DB_NAME="default.realm"
DESTINATION_PATH="/Users/xyz/Desktop/${DB_NAME}"
NOT_PRESENT="List of devices attached"
ADB_FOUND=`${ADB_PATH}/adb devices | tail -2 | head -1 | cut -f 1 | sed 's/ *$//g'`
if [[ ${ADB_FOUND} == ${NOT_PRESENT} ]]; then
echo "Make sure a device is connected"
else
${ADB_PATH}/adb exec-out run-as ${PACKAGE_NAME} cat files/${DB_NAME} > ${DESTINATION_PATH}
fi
This is a bit late, but installing adbd Insecure worked for me. It makes adb run in root mode on production ("secure") devices, which is what you likely have.
A paid version is also available on Google Play if you want to support the developer.
I had a similar problem to yours on windows as the following.
D:\ProgramFiles\Android> adb pull /data/local/tmp/com.packagename_dumped_1766.dex D:\ProgramFiles\Android\com.packagename_dumped_1766.dex
adb: error: failed to copy '/data/local/tmp/com.packagename_dumped_1766.dex' to 'D:\ProgramFiles\Android\com.packagename_dumped_1766.dex': remote Permission denied
My solution:
At first I also made an attempt to use cat as ansi_lumen answered, but I got into trouble about CR and LR (\r\n) characters.
And then I just had to change those file permisions by chmod and pulled again to this problem was solved without introducing other problems. After that, may
we need to restore their original permissions as Goran Devs answered.
So just pay a little attention.
TL;DR
My story:
Firstly, I used the cat to download all files from android to my windows,
#echo off
cd /d %~dp0
:: %~dp0 = D:\ProgramFiles\Android\
SET ThisBatDir=%~dp0
:: adb shell ls /data/local/tmp/com.packagename_dumped_* > %~dp0\dump_file_list.txt
FOR /f "delims=" %%a in ('adb shell ls /data/local/tmp/com.packagename_dumped_*') do call :processline %%a %%~nxa
goto :eof
:: https://stackoverflow.com/questions/232651/why-the-system-cannot-find-the-batch-label-specified-is-thrown-even-if-label-e
:processline
SET RemoteFullPath=%1
set FileName=%2
:: echo "%RemoteFullPath%|%ThisBatDir%|%FileName%"
call adb shell su -c cat %RemoteFullPath% > %ThisBatDir%%FileName%
goto :eof
:eof
However, those downloaded dex files were broken because of CR and LR (\r\n) characters on windows.
We can use hexdump to inspect its content in Hex+ASCII form (or Notepad++ with "View > Show Symbol > Show All Characters" checked). Note, the 5th and 6th byte (0d 0a)).

Now, jadx-gui-dev.exe or sh d2j-dex2jar.sh -f ~/path/to/apk_to_decompile.apk could properly enjoy them.
The pull command is:
adb pull source dest
When you write:
adb pull /data/data/path.to.package/databases/data /sdcard/test
It means that you'll pull from /data/data/path.to.package/databases/data and you'll copy it to /sdcard/test, but the destination MUST be a local directory. You may write C:\Users\YourName\temp instead.
For example:
adb pull /data/data/path.to.package/databases/data c:\Users\YourName\temp
