Replicating a SQL Server database for read access -


i have application in production own database more 10 years.

i'm developing new application (kind of reporting application) needs read access database.

in order not linked database , able use newer dal (entity framework 6 code first) decided start new empty database, , added tables , columns need (different names production one).

now need way update new database production database regularly (would best if -almost- immediate).

i hesitated ask question on http://dba.stackexchange.com i'm not limited using sql server job (i can develop , run custom application if needed).

i made searches , had (part-of) solutions :

  1. using transactional replication create smaller database (with tables/columns need). far can see, fact have different table names / columns names problematic. can use create smaller database automatically replicated sql server, still need replicate database new 1 (it may avoid production database stressed?)

  2. using triggers insert/update/delete rows

  3. creating custom job (either sql job or windows service runs every x minutes) updates necessary tables (i have lasteditdate updated trigger on tables, can know row has been updated since last replication)

do advice or maybe other solutions didn't foresee?

thanks

i think transactional replication better using triggers. resources used in source server/database due trigger fires each dml transaction.

transactional rep scheduled sql job , run few times day/night or part of nightly scheduled job. depends on how busy source db is...

there 1 more thing try - db mirroring. depends on sql server version.

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...
