I am having a problem while using the below command in the windows operating system and I have installed the oracle 10g server on my local machine which I am able to connect using client IDE
When I try to use the below command to import a dump file in my local DB
"imp system/ file=tms.dump log=test.log" in command prompt
where the binary of imp and the dump file is located in
"C:\oraclexe\app\oracle\product\10.2.0\server\bin"
I am getting the below error
error: unable to write logfile
I do not know how to create the log file
Thanks
The most likely reason for the error is that you are using an account which doesn't have write privileges on bin. You haven't specified a path, so like most utilities, imp will write its log files to the current directory.
bin is traditionally the sub-directory for holding executables. It is a very bad idea to use it for storing application data such as dump files.
Instead you should be working from a different location, ideally some sub-directory which you use solely for storing dump files. Either way, it must be a directory for which your user has write privileges.

I'm trying to backup a database which uses mongodb (Ubuntu LTS 18.04)
So I managed to run mongodump command without any errors but still I can't find the location of the backup database. I only used the mongodump command so it must save it in the default location. Can someone help me?
Thanks
By default it will save your dumped data into directory dump which will be created in the same directory you run the mongodump command.
You can also specify the out folder for the dump like so:
mongodump -u"username" -p"xxxxxx" --db=dbname --out=mongodata/

I have just instally successfully db2 on my linux machine, but I am not able to create a database.
When I make CREATE DATABASE ABC; I get the error that I haven't the authorization to create it...how can I get this authorization?
When you install DB2, you most probably use the root user of the Linux server.
Then in installing phase, you provide a user which will have the SYSADM and DBADM rights. That means DB2 creates a user which has all rights on the database(database admin).
So, after installation, you have to switch to that user to have rights to create a new database.
Depending on the version you installed, that username might be changed. But DB2 uses db2inst1 by default as administrator user.
Check your /home directory. You will see a new user(most probably db2inst1). Then switch to that user with:
su - db2inst1
then issue:
db2 CREATE DATABASE ABC
Let me know if you have a problem, also please provide your /home directory and the error message you get.
You can check details of create db command and related authorization required here on DB2 Info Center:
http://www-01.ibm.com/support/knowledgecenter/SSEPGG_10.5.0/com.ibm.db2.luw.admin.cmd.doc/doc/r0001941.html?cp=SSEPGG_10.5.0%2F3-5-2-4-21&lang=en
As said above, this should work if you login as instance user. Most of times you do not need root access with DB2.

I'm attempting to install Bugzilla on a server with a MySQL database on it already. The database is on E: (for space) and Bugzilla is on C:. Currently Bugzilla does not have a database associated with it, and the perl checksetup script looks for a drive local database.
How can I attempt to get bugzilla to target the database on my other drive? Is there a line I can change in the initial scripts to do this?
You tell Bugzilla how to connect to the database server in the localconfig file.
$db_driver = mysql
# The DNS name of the host that the database server runs on.
$db_host = localhost
I believe with MySQL you can also directly connect via a local socket. Be sure to follow the Bugzilla installation instructions for setting up a database, a database user and password for the connection to use. The tables will be set up automatically by Bugzilla's setup scripts.

I am trying to connect Oracle 10g database server from my client PC using toad 10 Commercial. I have Oracle 10g installed in my PC. When I try to connect, it gives error Can't initialize OCI.Error -1 .
So far I am able to perform tnsping to the oracle server. I have all the settings working in my tnsnames.ora.
Any suggestions are highly appreciated.
Thanks.
Found the solution myself. The problem was with windows 7 permission issue.
I opened Toad with run as administrator , privilege and the problem get solved.
Taken from https://support.quest.com/SolutionDetail.aspx?id=SOL61710
RESOLUTION 1:
Right-click the Toad for Oracle shortcut and select "Run as Administrator" to avoid the error.
RESOLUTION 2:
Right-click the Toad for Oracle shortcut | Properties | Compatibility Tab | check mark "Run this program in compatibility mode for" | choose "Windows XP Service Pack 3" from the drop-down list.
RESOLUTION 3:
Right-click My Computer | Properties | Advanced tab | Environment Variables | under ‘System Variables’ (lower part) | check if you have an entry for ORACLE_HOME. If yes, rename it to ORACLE_HOME_OLD, and then re-test the issue.
RESOLUTION 4:
Upgrade your Oracle client to a version that is 10.2.0.4 or later.
I have another resolution. I had this issue ater setting NLS_LANG environment variable to LATIN AMERICAN SPANISH.
When rebooting windows7, TOAD would not start showing error Can't initialize OCI. Error -1
I had to delete NLS_LANG / NLS_LANGUAGE environment variable.
Now i have to set NLS_LANGUAGE executing ALTER SESSION while logged in TOAD.
No OCI error anymore.
Hope it halps.
Kindly follow up the below steps to solve the (Can't initialize OCI. Error -1)title issue.
go to enviroment variable
remove all variable path in user variable.
Also check the permission.
Thanks

I think someone has already suggested:
1. stop the mongod
2. backup the data directory
Is it reliable, I mean, ensure 100% success to restore?
And I can't find which directory stores the data... any command can help me to find it?
If mongod process exits cleanly (that is, no crashes or kill -9 stuff), then it is safe to copy data files somewhere.
If your current installation breaks (for example, data corruption due to unclean shutdown), you can delete its files, copy that backup over and start mongod again.
Default data directory is /data/db, but it may be set to another value in your config file. For example, I set it to /var/lib/mongodb.
You can also use mongodump to do a backup from a live server (this may impact performance). Use mongorestore to restore backups made by mongodump.
At IGN we do hot backups via mongodump running as an hourly cron job, and take filer snapshots (NetApp storage) on a half-hourly basis. If your system is not too write heavy and you can afford write blocks, try using fsync and lock to flush the writes to the disk and prevent further writes. This can be followed by mongodump and upon completion you can unlock the db. Please note that you've to be admin to do so.
db.runCommand({fsync:1,lock:1})
