Yes, You either need Sun Cluster (3.2 beta supports ZFS) or do it manually by using zpool import/export. -- Best regards, Robertmailto:[EMAIL PROTECTED] http://milek.blogspot.com ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Not exactly front-line but devel Oracle instances and warehouse. It works. However no performance comparisons were done.

Also remember that some performance patches aren't yet in S10. Especially fix for not reading block is full overwrite is issued which can hurt performance. But once patch is released (someone stated it should be available at the end of September with other fixes).

[EMAIL PROTECTED] schrieb: Hi all, Does anybody use Oracle on ZFS in production (but not as a background/testing database but as a front line) ? I haven't used in production yet - but I'm planning by the end of the year. I did some performance stress tests on ZFS vs. UFS+SVM. For testing I used the TPC-H benchmark as base and tested on SAN (Symmetrix DMX1000 storage). The test consists of four parts: 1. creation of database (CREATE DATABASE ...; @catalog.sql; @catproc.sql) 2. Importing Test data with sqlldr (TPC-H target size of 2 GB) 3. Run a single instance of the TPC-H benchmark 4. Run 4 (2 * NCPU) instances of the TPC-H benchmark Test 1: UFS performed slightly better Test 2: performance of UFS vs. ZFS was similar Test 3: ZFS was somewhat faster (<10%) Test 4: ZFS was much faster (>20%) Summing up the runtime of all 4 tests ZFS was ~12% faster (248 mins to 280 mins). I am interesting especially in: - how does it behave after a long time of using it. Becasue COW nature of ZFS I don't know how it influences performance of queries. I filled up the pool with random data so that the pool reached 100% usage during the benchmark (The benchmark needs a huge TEMP tablespace (with above 2GB data TEMP grew up to 20GB), so you can expect a lot of write I/O) The total performance dropped just by 1-2% - general opinion of such pair (ZFS + Oracle) Use compression and save a lot of space. Expect a space reduction of >50% by using compression even with filled up tablespaces. Oracle just worked on ZFS, no "strange" results. I had one panic, but this was related to the Emulex FC device driver, not to ZFS (in the meantime a Emulex patch has been released (120222/120223), don't know if it fixes this panic) The total runtime didn't change during my tests (<1%) if compression was turned on compared to compression off. The CPU usage increased by ~15%. So if you have fast CPUs give the CPUs something to do instead of just fooling around. - which version of Oracle This was Oracle 10g R2 on a FSC PrimePower (2 x 1350 MHz, 4 GB RAM) with Solaris 10 06/06. Currently I have only an older Xeon box with SAN connectivity for Solaris/x86 but Oracle 10gR2 still isn't released on 32bit x86 platforms[1]. 10gR1 needed much more space in the TEMP tablespace so I couldn't complete the tests.
