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 10.0.1.3.0 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 Tablespace5: Sequential Insert as select from Solaris into ASM Based Tablespace6: Transportable Tablespace based on NFS mounted filesystem + Move table7: Transportable Tablespace + Move table into FS based tablespace (scenario 1 with FS)8: Import data pump using network link9: Comparison test, move table in 8i, compare time with move on 10g

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

Compress Test Preparation Steps top

Prepare Source Data on the 8.1.7.4 database

Create a tablespace to exchange partitions create tablespace testcompress datafile '/srvprd/zyhist/od04/testcompress_01.dbf' size 8000m extent management local; Check which tab_det_all partitions are not part of the zy view: select add_months(to_date('050201','yymmdd'),-12) from dual; 01-FEB-04 This mean that the view includes only partitions older than 01/02/2004. We can use newer partitions to transport them to a side database. select partition_name, tablespace_name from dba_tab_partitions where table_name='TAB_DET_ALL_P' AND partition_name like 'P0409%' ; select partition_name, tablespace_name from dba_tab_partitions where table_name='TAB_DET_ALL_P' AND partition_name like 'P0410%' ; PARTITION_NAME TABLESPACE_NAME P0409_BC13 TBS_CDT_0409_BC13_BIG P0409_BC19 TBS_CDT_0409_BC19_BIG P0409_BC25 TBS_CDT_0409_BC25_BIG P0410_BC01 TBS_CDT_0410_BC01_BIG

P0410_BC07 TBS_CDT_0410_BC07_BIG P0410_BC13 TBS_CDT_0410_BC13_BIG After checking the objects contained on the last tablespace I did find that it contain several related objects. Because the size of one partition is quite big, 29GB I did choose to transport the whole tablespace with all its objects into a side tablespace that will be used to perform all tests.

Prepare a script to create the tables and indexes that sit on the tablespace to transport

create table cmp_TAB_DET_ALL_P tablespace testcompress as select * from TAB_DET_ALL_P where 1=2; create table cmp_CALL_PART_TAB_P tablespace testcompress as select * from CALL_PART_TAB_P where 1=2 ; create table cmp_CONT_FREE_UNIT_TAB_P tablespace testcompress as select * from CONT_FREE_UNIT_TAB_P where 1=2; create table cmp_INCOME_DETAIL_TAB_P tablespace testcompress as select * from INCOME_DETAIL_TAB_P where 1=2; create index cmp_IND_TAB_DET_ALL on cmp_TAB_DET_ALL_P (CUST_CODE_10, INVOICE_NUM_10, CUST_CODE_50, CONTRACT_NUM_20) tablespace testcompress; create index cmp_CALL_PART_TAB_P_I1 on cmp_CALL_PART_TAB_P (CUST_CODE_10, INVOICE_NUM_10, CUST_CODE_50, CONTRACT_NUM_20) tablespace testcompress; create unique index cmp_PK_CONT_FREE_UNIT_TAB_P on cmp_CONT_FREE_UNIT_TAB_P (CUST_CODE_10, INVOICE_NUM_10, CUST_CODE_50, CONTRACT_NUM_20, CONT_FU_SEQ_NUM, INVOICE_DATE_10) tablespace testcompress;

create unique index cmp_PK_INCOME_DETAIL_TAB_P on cmp_INCOME_DETAIL_TAB_P (INCOME_ID_81, CYCLE_DATE_81) tablespace testcompress;

Prepare a script to exchange the partitions with the new tables

set echo on pages 5000 lines 120 spool excobj.log alter table TAB_DET_ALL_P exchange partition P0410_BC13 with table cmp_TAB_DET_ALL_P including indexes; alter table CALL_PART_TAB_P exchange partition P0410_BC13 with table cmp_CALL_PART_TAB_P including indexes; alter table CONT_FREE_UNIT_TAB_P exchange partition P0410_BC13 with table cmp_CONT_FREE_UNIT_TAB_P including indexes; alter table INCOME_DETAIL_TAB_P exchange partition P0410_BC13 with table cmp_INCOME_DETAIL_TAB_P including indexes; spool off;

Set the tablespace to transport to read only

Automatic Storage Manager (ASM) disks preparation

The preparation of ASM disks consist on marking unformatted disks to make them available for ASM.

Request unformatted disks from storage (not raw devices), check their names using fdisk -l as root, in this example disks /dev/sdc and /dev/sdd were added: [root@srvtst2 root]# fdisk -l Disk /dev/sda: 73.2 GB, 73272393728 bytes 255 heads, 63 sectors/track, 8908 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 6819 54773586 83 Linux /dev/sda2 6820 7863 8385930 82 Linux swap /dev/sda3 7864 8907 8385930 82 Linux swap Disk /dev/sdb: 75.1 GB, 75161927680 bytes 255 heads, 63 sectors/track, 9137 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sdb doesn't contain a valid partition table Disk /dev/sdc: 53.6 GB, 53686566912 bytes 255 heads, 63 sectors/track, 6527 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdc doesn't contain a valid partition table Disk /dev/sdd: 53.6 GB, 53687091200 bytes 255 heads, 63 sectors/track, 6527 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System Caution: Disks need to be made available without any sort of logical definition. ie: if the fdisk show then as devices like in this output, oracleasm still will be able to stamp them as ASM available disks but it will be unable to find them when it need to create a disk group: [root@srvtst2 init.d]# fdisk-l … (look on the output for your disks) Device Boot Start End Blocks Id System /dev/sdc1 1 6527 52428096 5 Extended <<< this is incorrect Disk /dev/sdd: 53.6 GB, 53687091200 bytes 255 heads, 63 sectors/track, 6527 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdd1 1 6527 52428096 5 Extended <<< this is incorrect Stamp the empty disks as ASM available: [root@srvtst2 init.d]# /etc/init.d/oracleasm createdisk VOL1 /dev/sdc [root@srvtst2 init.d]# /etc/init.d/oracleasm createdisk VOL2 /dev/sdd Query the new ASM enabled disks: [root@srvtst2 init.d]# /etc/init.d/oracleasm querydisk /dev/sdc Disk "/dev/sdc" is marked an ASM disk

Start ASM instance fail with ORA-29701 unable to connect to Cluster Manager This problem was seen after taking care of changing the UID and GID of oracle user to match that of Solaris. The change was done after shutting down the database and asm instance. But I forgot to shutdown also the asm manager. This error was also seen after killing all old cssd processes, and before restarting asm manager:

SQL> startup ASM instance started Total System Global Area 130023424 bytes Fixed Size 1320472 bytes Variable Size 128702952 bytes Database Buffers 0 bytes Redo Buffers 0 bytes ORA-15032: not all alterations performed ORA-15063: diskgroup "DATA" lacks quorum of 2 PST disks; 0 found SQL> shutdown ORA-15100: invalid or missing diskgroup name

Steps that solved the problem Connect as root, check if there are cssd processes up, clean them up Execute as root:

/etc/init.d/oracleasm stop /etc/init.d/oracleasm start

/etc/init.d/init.cssd start Start the ASM instance as oracle
