All the tables needs to be imported in one go.
Can somebody help me in how to achieve this ?
Thankyou in adavnce.

First, the DB2 backups do not have that name structure. You should have a file inside that .gz that should have a name like this
SAMPLE.0.db2inst1.NODE0000.CATN0000.20131224235959.001
It gives the database name, the backup type; the instance that host the database; the node (when using DPF); the timestamp; and the file number.
Normally, it just change the timestamp. And in order to restore the db you should go to the directory where the file is, and then just type:
db2 restore db sample
Eventually, if it does not work, you should specify the timestamp, directory or other things:
db2 restore db sample from /dir taken at 20131224235959
If you change the instance, you should rebind some packages. Also, you should be sure that the security structure is the same in the new installation (/etc/passwd and /etc/group have the same users and groups used in DB2)
For more information, please check: http://pic.dhe.ibm.com/infocenter/db2luw/v10r5/topic/com.ibm.db2.luw.admin.ha.doc/doc/c0006237.html
You can use db2move command
db2move sample export
db2move sample import
where sample is the database name.
If you are having .dmp file then you can use below commands import .dmp file.
If you have dmp file in tar or zip you need to extract this.
db2 –c- -svtf db2dump.dmp > log.txt
Note:
It is different then: restore command as below :
restore db from Path_of_the_backup_file.
eg: restore db QAST from C:\Backups\Backup_location
backup db to C:\Backups\Backup_location.
eg: restore db QISST from C:\Backups\Backup_location

I have taken full backup of postgresql database which consists of 100 databases. The backup format is .sql (eg pg_dumpall.exe -U postgres > D:\Backup\fullbkp.sql) now one of my database got crashed and I want to extract this file to get that database backup only for restoration.
I have searched a lot but couldn't find any way to decompress so that I can get that particular database from full backup file.
Please suggest !!!!

Such a backup is not compressed. Also, it contains a backup of all databases in th cluster, and there is no easy way to extract a single database.
Create a new PostgreSQL cluster with initdb, restore the dump there using psql, then use pg_dump to extract the single database you need.
I'm trying to export my database created in Google Cloud Sql and import it into a new external server.
I tried to create a sql backup through the google console, downloaded it and copied it to the new server via filezilla and then launched the following command:
psql -U postgres -d ciclods-db -1 -f Backup-db_Cloud_SQL_Export_2019-03-23\ \(17_01_19\)
but i get this output:
ERROR: role "cloudsqladmin" does not exist
REVOKE
ERROR: role
"cloudsqlsuperuser" does not exist GRANT
what is the right procedure to follow in these cases?
I have resolved the same problem by locating and deleting the two lines from the exported sql file with "cloudsqladmin". My app does not use it anyway.
to do this task you can follow the official GCP guide about How to export data from Cloud SQL[1] in that document they give you the option to export the data into a dump file or csv files which can be used for other tools.
https://cloud.google.com/sql/docs/mysql/import-export/exporting
In order to create the export file, you have to do it from a command line and use additional flags. As per documentation‘s “Exporting data to a SQL dump file”, there is a section on Exporting data from an externally-managed database server.
As well you can find there the option to export the data into a CSV file.
When I am restoring the database, by default data is going in C drive, but when I installed the db2 that time I specify the path in D drive only.
Also, sample database files created by db2 is stored in D drive.
Can anyone please tell me what is the issue?
I have run this command:
SELECT * FROM SYSIBMADM.DBPATHS
below is the result i fetched:
LOGPATH- D:\DB2\NODE000\SQL00001\SQLOGDIR\
DB_STORAGE_PATH- C:\
LOCAL_DB_DIRECTORY - D:\DB2\NODE000\SQLOGDIR\
DBPATH - D:\DB2\NODE000\SQL00001\
I Want to change this DB_STORAGE_PATH C:\ to D:\ for all the database which i will be restoring.
You can run db2set from db2 command line that will confirm you wheather db2 installed on path with other information;
db2-command-line> db2set
DB2_ATS_ENABLE=YES
DB2_CREATE_DB_ON_PATH=YES
DB2INSTPROF=C:\where\db2\installed\IBM\DB2\DB2COPY1
DB2COMM=TCPIP
You can get more information of Directory structure for your installed DB2 database product (Windows) here
You can run the following command SELECT * FROM SYSIBMADM.DBPATHS. This will give details of following variables of your installed db2 database;
LOGPATH
DB_STORAGE_PATH
LOCAL_DB_DIRECTORY
DBPATH
These commands will provide you enough information to locate your installed database. Then you can restore your database providing the exact path.
To add a storage path to an existing database, issue the following ALTER DATABASE statement:
ALTER DATABASE database-name ADD STORAGE ON storage-path
After adding one or more storage paths to the database, you may use the ALTER TABLESPACE statement to rebalance table spaces in the database so that they start to use the new storage paths immediately.
DB2 has a configuration parameter for the default path for databases, dftdbpath. In addition, the command db2sampl to create a sample database has an option dbpath to specify where to place that database.
db2sample -dbpath D:
The above would place the new database on drive D:.
You will find that there are default paths for certain operations. The overview of DB2 database manager configuration parameters has lists most of them.
For your specific issue I would assume that a parameter was changed some time after DB2 was installed and used initially.
For RESTORE be aware that the options TO and DBPATH are ignored if restoring an existing database.
I have a "cinema" DB in postgres and I want to dump all its tables and data in a cinema.sql file.
This file will contain all the sql code for re-creating the schema, tables and filling them with the data.
I already have a bank.sql file (for the "bank" DB) which I can execute via PSQL console in pg Admin III and import using the command
/i *path to my bank.sql file*
Now, I want to produce a cinema.sql file like bank.sql, but I don't know how to do it.
It's not the backup/restore feature of course, because it produces a .backup file.
I've also tried
pg dump > cinema.dump
In PSQL console but I can't find a .sql file anywhere, so I don't think it is what I'm looking for either.
Couldn't find anything useful for what I need in Postgres documentation unfortunately so I hope you can help me because I'm just a beginner.
Thanks.
As mentioned in the comments and the documentation, you should use pg_dump command line tool.
pg_dump cinema > cinema.sql
I've made it! Don't know if it's the 100% right way to do it, though, but I think it is.
I'll report here just in case someone else might need this in the future and it can be of help.
I selected the db I wanted to dump in .sql file and then right click -> backup.
Here, as format, I chose plain instead of custom, and "mydbdump.sql" as file name.
In Dump Options #1 and Dump Options #2 I checked the checkboxes to include everything I needed (e.g. "include CREATE DATABASE statement").
I compared this newly created .sql dump with the one I already had (using Notepad++) and they look the same (even if, of course, they are from different dbs).
I'm working in Teradata Database Express 14.04
I took the particular database build( backup the database) in Teradata Database.
The Archived file is stored in /roor/Documents/TD_BUILD. The file extension of TD_BUILD is (.File).
Now, how to import that file into new Database in Teradata?
To restore to a different system and/or database or to restore a dropped table you need a COPY instead of a RESTORE:
copy data tables(xyz),release lock,file=test;
Caution, restoring on database level drops all objects within first, i.e. ARCMAIN submits a DELETE DATABASE.
If you restore to a different database:
copy data tables(newdb) (from (xyz)),release lock,file=test;
