6 About the Test This test was designed to check the benefit of data compression to store read only data. The test was performed using Oracle RDBMS 10.g version on Linux and Solaris. This test was intended to check how long may take to transfer 6 TB of historic data to a 10g Linux based database. The test was implemented by taking a single partition from the main historic table as sample data, plugging its tablespace into a 10g database in UNIX, Solaris 5.8 used as a staging area for all the tests. Each test moved 31 G of data, 8 Scenarios were tested: 1: Alter Table Move Compress into ASM Based Tablespace. 2: 10g Export Data Pump and Import Data Pump into ASM Based Tablespace. 3: 10g Parallel export Data Pump and import from NFS mounted File System, into ASM Based Tablespace. 4: Parallel Insert as select from Solaris into ASM Based Tablespace 5: Sequential Insert as select from Solaris into ASM Based Tablespace 6: Transportable Tablespace based on NFS mounted filesystem + Move table 7: Transportable Tablespace + Move table into FS based tablespace (scenario 1 with FS) 8: Import data pump using network link 9: Comparison test, move table in 8i, compare time with move on 10g STEP TEST 1: TEST 2: TEST 3: TEST 4: TEST 5: TEST 6: TEST 7: TEST 8: TEST 9: CONVERT TIME 54 Min 0 Min 0 Min 0 Min 0 Min 54 Min 54 Min 0 Min 0 Min EXPORT TIME 0 Min 41 Min 0 Min 0 Min 0 Min 0 Min 0 Min 0 Min 0 Min FTP TIME 86 Min 57 Min 0 Min 0 Min 0 Min 0 Min 86 Min 0 Min 0 Min MOVE TIME 17 Min 0 Min 0 Min 0 Min 0 Min 51 Min 18 Min 0 Min 40 Min IMPORT TIME 0 Min 74 Min 79 Min 109 Min 126 Min 0 Min 0 Min 124 Min 0 Min TOTAL TIME 157 Min 172 Min 120 Min 109 Min 126 Min 105 Min 158 Min 124 Min not relevant COMPRESSION 73 % 73 % 71 % 63 % 74% 73% 73% 13% 0% Based on the tests results the best estimation to move 6 Tera of data is: Simplest Test : #5 Insert as select from source = ~4.2 min/giga, 420 hours, 17.5 days. Best Test : #6 Upgrade to 10g / Convert/ NFS mount & Move = ~3.5 min/giga, 350 hours, 14.5 days
