SQL Anywhere - database size 1 terabyte and more

[former_SQLA_member1694890]

We are using SQL Anywhere SA12 (on Windows(32 bit) and Linux(64 bit)) for storing statistic data till 1 years. Till now max size of database(using 3(three) dbspaces) was about 300-400 GB. On one of our new customer, database size will growing till 1-1.2 terabyte. Have someone experience to work with SQL Anywhere databases of this terabyte size, could it work properly?

Thanks, Hanan Brener

I haven't used SQLA databases that big, but I have full faith that there would be no problem as long as you were working within the hardware requirements-- and your database is well designed.

One caution though... big files take a long tim to move around... so in the event you have to recover from a backup onto a new server, or some other catastrophic situation, think about how long that terabyte file will take to get from the backup location to the new server. Can your application take that much downtime? In nearly 20 years of using SQLA and its predecessors, I can count on one hand the number of times I've had to do this, but when it happens, it happens. Just plan for it.

For that large DB's it can sometimes be a benefit to have a replicated/mirrored server, just in case the main db goes down.

But of course having a second server sized correctly and all the replication/mirror traffic too can be a challenge.
