I have been using the sql loader method to load the .dat file to my database. However, it said I have such error:
Internal error: ulconnect: OCIServerAttach [0]
ORA-12154: TNS:could not resolve the connect identifier specified
so, I was looking for an alternative way to load data into my database. Thanks for your help

I am trying to generate the report from OracleDB --19c with ora2pg --V23.1.
Command Used: ora2pg -t show_report --dump_as_html -l db_report_filename.html -c E:\ora2pg\ora2pg.cong
Error generated in html report:
FATAL: ORA-00604: error occurred at recursive SQL level 1 ORA-08177: can't serialize access for this transaction (DBD ERROR: OCIStmtExecute)
Looking for ideas to resolve this issue.
This issue was fixed when a configuration change in ora2pg conf file was changed
Data are exported in serialized transaction mode to have a consistent snapshot of the data, see Oracle documentation about what parameter to increase to not have this issue. Or if you are sure that no modification are done in the Oracle database you can force Ora2Pg to use a readonly transaction instead, see TRANSACTION directive in ora2pg.conf
I am getting below error wgile exporting a table into csv in hana studio.
SAP DBTech JDBC: [2]: general error: Remote export failed: export size exceeds 20% of available memory, please use server-local export.
My table has 186 millions records
Please let me know how to resolve this issue and how to run in server - local export
Pallavi there is export limitation applied to the HANA users. You can check those by going into settings of your hana studio. Thats one you need to sort out but if there those many rows as you mentioned above i would suggest to slice the extract into multiple extracts.
Here is the admin settings link from SAP which will guide you to the particular setting i am referring to:

Look for query limit and exported data to file
I have an empty SQLlite database. Next to that, I have 6 input files (delimited, excel, json, xml).
Now, all I want to do is load the input files into the empty database.
I tried to connect one input file with the DB and just run it. That didn't work (the DB doens't have anything in it, I suspect that is a problem).
Then, I tried to connect an input file with a tMap, define the table there, define the schema and connect the tMap to the DB (tSQLliteOutput).
When I tried to run it, I receive the following error:
Starting job ProductDemo_Load at 16:46 15/11/2015.

I see there's something wrong with the import, but what exactly?
What should I do in order to succesfully load the data from the input files in the database?
I did the exact steps from this little tutorial:
Talend Job: load data into database.
Most talend output components have create table if not exists option.. Did u checked this in your tsqliteoutput..error seems that when talend is inserting data into empty database your table it is not able to find it as it does not exists.. So you to tell talend to create the table first..
I need to parse a CSV file and write the data to a Vertica database. The issue is that I get an error when I create a Vertica database connection in Spoon. The following is the error at the end of the post.
I tried copying the following two JAR files and adding them to libext/jdbc:
vertica-jdbc-4.1.14.jar and vertica-jdk5-6.1.2-0.jar
But the above didn't help. I am looking for pointers!
Error:
Error connecting to database [Vertica Dev] : org.pentaho.di.core.exception.KettleDatabaseException:
Error occured while trying to connect to the database
Exception while loading class
com.vertica.jdbc.Driver
org.pentaho.di.core.exception.KettleDatabaseException:
Error occured while trying to connect to the database
Exception while loading class
com.vertica.jdbc.Driver
at org.pentaho.di.core.database.Database.normalConnect(Database.java:366)
The two JAR files you copied are of two different versions of Vertica and do not use the same class.
vertica-jdk5-6.1.2-0.jar will expose com.vertica.jdbc.Driver whereas version 4 will expose com.vertica.Driver.
The error message thus makes obvious that Pentaho is looking for com.vertica.jdbc.Driver (version 5, thus). If it fails, it probably is because the JAR version 4 is loaded first.
Try to delete the version 4 only from the libext/jdbc, keep the version 5, and restart Pentaho.
On a side note, this class is hardcoded in Pentaho, so if you do need to use the JAR version 4 and feel adventurous, you just need to get the Pentaho source, update VerticaDatabaseMeta.java, and recompile.
I detached a database, and when i try to re-attach it i am getting error:
CREATE FILE encountered operating system error 5(failed to retrieve text for this error. Reason: 15105) while attempting to open or create the physical file 'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\RoadMap.mdf'. (Microsoft SQL Server, Error: 5123)
Is there a way i can delete that database and create new one instead of re-attaching it.
I Just had to delete the database logs from the defualt location and i was able to create new database.
Thanks
