I'm trying to upload a CSV file to DB2 with the following command:
db2 import from MY_FILE.csv of del insert into TEST.TABLE
The file contains more that 2 millions rows. I got transaction log is full when I try to upload it.
Is there a way to upload it without getting this error ?
Yup. :)
You can use the COMMITCOUNT AUTOMATIC option for IMPORT. With that option IMPORT will determine when your transaction logs will be full and automatically commit the data. That way transaction logs are "cleared" and DB2 is ready for the next chunk of data.

The original code is a simple SQL import :
LOAD DATA LOCAL INFILE 'D:/FTP/foo/foo.csv'
INTO TABLE error_logs
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
ESCAPED BY ''
LINES STARTING BY ''
TERMINATED BY '\n'
IGNORE 1 LINES
(Server,Client,Error,Time);
I need to migrate a web portal (from SQL to Postgres[I know there are tools for that, but its not the question]) and the issue is i am no more working on local.
I didn't see anybody ask the question in this way : import .csv from a remote server to a postgres db.
I think i have to use COPY but i dont get the right syntax...
Thanks for your attention.
the copy command is an option to do this.
I had to do this once time.
How to import CSV file data into a PostgreSQL table?
Copying PostgreSQL database to another server
We have one application where we have db2 10.1 as database.
Now one requirement came in which we need to interface few tables to HOST which is on IBM DB2 VSE 7.4
I tried to execute load command with client option but it give "SQL1325N The remote database environment does not support the command or one
of the command options." error.
command is :"D:\tempdata>db2 load client from app.tbl of ixf
insert into host.tbl"
Many post says that its not allow to use load from 10.1 to VSE Z/OS.
Another option I tried is import but its too slow and we need to delete records every time as truncate is not available.
Replication can be think for option but we would like to avoid replication.
Can anyone suggest way to achieve this. Load can be use or not?
It seems its not allow to use load from remote machine. But wondering what is use of CLIENT option in load then.
Finally we decided to use import utility after deleting HOST DB2 records. In that we need to execute delete and import command on part of table. If we try to import or delete big table at one go it give error of log file size full.
Hope this will help.
I have a DB2 v9.7 Dump(.gz format) which i need to import to an another DB2 database of same version.
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 a CSV file, but this could apply to any txt, data, or xls file. (xlsx) I have exported the data from one source and I want to import the data into a DB2 table.
I first tried Data Tools Plugin (DTP) in eclipse Helios (3.6.3) by right clicking on the table and selecting: Data > Load...
But I got this error:
Loading "myschema"."mytable"... com.ibm.db2.jcc.am.SqlException:
[jcc][10103][10941][4.14.113] Method executeQuery cannot be used for
update. ERRORCODE=-4476, SQLSTATE=null Data loading failed.
Then I tried Eclipse SQL Explorer on Eclipse Juno, but it does not support data import.
How do I get past this error so I can import?
You can import a CSV file directly into DB2 via the IMPORT or LOAD command, even with XML or BLOB as part of the data to import.
The procedure to import depends on the structure of the file you are going to import. Probably you should modify the default behaviour of these commands; DB2 has many option to adapt the command to the input file.
For more information about:
The import command: http://publib.boulder.ibm.com/infocenter/db2luw/v10r1/topic/com.ibm.db2.luw.admin.cmd.doc/doc/r0008304.html
The Load command http://publib.boulder.ibm.com/infocenter/db2luw/v10r1/topic/com.ibm.db2.luw.admin.cmd.doc/doc/r0008305.html
I think your question was more oriented to: how to use Eclipse to import data in DB2 from a CSV file. However, as I said, you can do that directly via DB2.
If you are going to import a file like the next one, the only thing that you need is to have access to a db2 client.
data.txt
1,"Andres","2013-05-18"
2,"Tom","2011-04-16"
3,"Jessica","2002-03-09"
You import with
db2 import from data.txt of del insert into test
I solved this by installing Eclipse Juno (4.2) and Data Tools Plugin (DTP) 1.10.2.
Now Data > Load... will work fine. This is the new message I get:
Data loading was successful. 142 row(s) loaded. 135 row(s) could not
be loaded.
com.ibm.db2.jcc.am.go: DB2 SQL Error: SQLCODE=-407, SQLSTATE=23502,
SQLERRMC= , DRIVER=4.7.85 One or more values could not be set in the
following column(s): USER_TIME, USER_DATE
FYI for the entire process I was using this:
DB2 driver: /opt/IBM/db2/V9.7/java
With jar files: db2jcc4.jar, db2jcc_license_cisuz.jar
Driver Class: com.ibm.db2.jcc.DB2Driver
You can import using DB2 "Control Center" *
Right Click the table and select "Import"
Then specify the csv file and message file
message file is important because in the case of failed upload, you can find the error cause in the message file
* Control Center is now deprecated in favor of "Data Studio"
From the db2 console, try this:
Import from 'yourcommaseparatedfile.csv' of del insert into "SCHEMA"."TABLE"
Regards =)
db2 'import from /users/n0sdsds/test.csv of del insert into ENTPRISE.tmp_x'
My product needs to support Oracle, SQLServer, and DB2 v9. We are trying to figure out the most efficient way to periodically load data into the database. This currently takes 40+ minutes with individual insert statements, but just a few minutes when we use SQLLDR or BCP. Is there an equivalent in DB2 that allows CSV data to be loaded into the database quickly?
Our software runs on windows, so we need to assume that the database is running on a remote system.

If the data is in CSV format try import the data with the delimiter as coma(,)
db2 import from <filename> of del modified by coldel, insert into <Table Nmae>
Or else you ca use Load command - load from file
db2 load client from /u/user/data.del of del
modified by coldel, insert into mytable
