I am trying to take backup of postgres from InstallAnyWhere which is installer for linux and windows machine.

I am calling pg_dump from Java process builder as command line below

cmdLine: [./pg_dump, -Ft, -b, -f, /tmp/temp1389348461928/postgresbackup, -h, 127.0.0.1, -p, 5432, -U, postgres, dbname]

Cannot run program "./pg_dump": java.io.IOException: error=2, No such file or directory

cmdLine is passed to the process Builder and PGPASSWORD is set before calling pg_dump

Same if call pg_dump from terminal it works fine.

 ./pg_dump -Ft -b -f /tmp/temp1389018812029/postgresbackup.tar -h 127.0.0.1 -p 5432 -U postgres dbname

Thanks, Brijesh

@Rugal i am having pg_dump file in directory along with required libraries –  Brijesh Jan 10 at 10:27
    
Is the current working directory of the Java process the one that contains pg_dump? Or did you set the directory of the ProcessBuilder? –  harmic Jan 10 at 10:46
    
i am not setting explicitly any directory to the process builder just passing cmdLine parameters to the process builder. Do we need to set working directory?. –  Brijesh Jan 10 at 11:16

I don't understand why this was migrated from Stackoverflow as it is clearly a programming/Java problem. Not a "DBA problem" –  a_horse_with_no_name Jan 10 at 13:19
