1 D0 Taking Stock By Anil Kumar CD/LSCS/DBI/DBA June 11, 2007

2 Outline  Infrastructure  Space Usage  Capacity Planning  Backup & Recovery  SAM Schema  Accomplishments  What’s Next  Concerns  Q & A

3 D0 offline Production/Integration Infrastructure  8 900MHz CPU 32G RAM  The machine has a Clariion 4500 hardware raid array  Oracle Server 10gR2 (64 bit) on Solaris 2.9 (64 bit)  Load Avg. 4-6 CPU usage ~53%, Memory Free : 50% ( 16GB)  Uptime excluding scheduled down times 100% Uptime since June, 2006 vs last year.

4 D0 offline production Luminosity  Sun v40z with 2 AMD 844MHz CPU, RHEL3 x86_64, 16G RAM  2 Ultra 160 RAID controllers  Oracle server 10gR2  Load Avg. 1 CPU usage ~3-60%, Memory Free : 20M  Uptime excluding scheduled down times 100% since June 2006

5 D0 offline development Infrastructure D0ora1  Sun E4500  MHz CPU, 4GB of RAM  Oracle 10gR2 64 bit on Solaris 2.9  Load Avg 1-2, CPU usage ~33%, Memory Free 19% D0lum1  Sun v40z with 2 844MHz AMD CPU  RHEL3 x86_64  16G RAM  Oracle server 10gR2  Load Avg 1, CPU usage ~4%, Memory Free 74M

6 Space Usage

7 Space Usage Summary  d0ofprd1 257 GB used. d0ofint1 185 GB used. 2TB available for int and production.  d0ofdev1 107 GB Used 165GB is available for use.  d0oflumd 298GB used doflumi 495MB used 170GB is available for d0oflumd and d0oflumi  D0oflump 627GB used 1 TB is available.

8 Capacity Planning  Next three years expected growth 300Gb SAM growth ~80Gb/year and other apps 10Gb/year (this exclude Luminosity DB ) We have around 2TB available.  Next three years Luminosity growth is 500Gb. There is 1TB available.

9 Back-up/Recovery  D0ofprd1  Daily, 4 days of archives.  Allocated 4TB, Used 1.2TB (2 copies), RMAN Back-up time -> 2 Hrs No Export. Both copies of rman backup to SAN. No local copy.  Backups taken to dcache 3x/week  D0lump  Daily, 4 days of archives  Allocated 3TB, Used 2.2 ( 2 copies), RMAN Back-up time -> 6 Hrs No Export. Both rman backup copies are on SAN. No local copy.  Backup to dcache daily.

10 SAM Schema  Production Deployments : Retiring Files v6_3 Indexes v6_4, v6_5,v6_6, v6_8, v6_9 Sequence Cache V6_7  Work-in-progress - v6_10 Global temporary tables.  Upgrade to Mini SAM as SAM Schema Evolved. -> This facilitate individual developers to have copy of SAM metadata and seed data available for server software rewrite if needed.  Discontinued supporting the postgres version of SAM schema as per last year taking stock meeting.

11 Accomplishments  Quarterly Database Security/OS patches Up-to-date.  Upgraded the d0 offline Lumi databases to 10gR2.  Upgraded the designer repository to 10gR2  Disk capacity upgrade for d0 offline lum db production db.  OS upgrade on d0online Db  Disk capacity Upgrade for d0online db machines.  Merged the monitoring of d0 online with central monitoring for all dbs.  Migrated the d0 online designer users to central designer repository.  Took over the System Support for d0 online db machines.  Deployed the rman enhancements to d0 online databases.  Deployed the rman_dcache for d0online prd databases.

12 Accomplishments  Depreciated the events on d0offline db. Recovered space ~800GB  Deployment SAM v6_0 through v6_8. This includes the SAM request system.  Began Testing and deployment of 3PAR SAN storage to replace clariion array.  Bundled the Redhat licenses into one P.O.  Deployed additional weekly schema analysis for SAM for tuning

13 What’s Next ?  Replacement of Aging Clariion Array with 3par SAN storage including int/prd d0 offline database instances to 3par array.  Take Over support for d0 online databases by end of June 2007  Upgrade the Oracle databases to version  ASO ( Advanced Security Option) Deployment

14 Concerns  Python Dcoracle to be built with Oracle 10g client. Oracle recommends client version should be same as Database Version. Any Oracle Patch may break Pyhton Dcoracle built with 8i client.  Single point of failure with D0 offline database.  Hardware for D0 DB server machines is very old. Should consider upgrading the hardware for d0 db servers.  Speaker Bureau schema in development db being used in production mode. This schema must be moved to production.  Not enough disk capacity on d0ofline lum dev/int machines to do production refresh. Note : Investigating hardware configuration if 3par array can be attached to d0lum1. This will facilitate the full integration refresh from production.
