Unanswered: problem with BCP Process on sybase database
I am facing a problem with bcp process on the following environment
OS - sun solaris
database - sybase
I have 13 tables in my database with max 8450782 rows in a table.
so I have write a script for unix, in which whole bcp process is done in one shot being a single process in background(bcp-out from source table , truncate on destination table,bcp-in ). in this way my all the 13 tables refreshes simultaniously.my tables have not any indexes,or other referential dependency.
some times this whole process slow down significantly.so is there any issue with multiple tables refreshing.
is my this approach is wrong or what i need to speed up the process.
any suggestion will be appriciated.
I think you might be limited by your disk I/O speeds. But things you can use to try and speed up the process is a fifo special file (man mkfifo) as the bcp file and a larger network packet size (bcp -A 8704)
