3. From steps 1. and 2. above we know that the spfile is 3584 bytes long and is stored in 2 mirrored extents: one on disk 0, the other on disk 24 (on disk group). We can find the OS path of the disks with the following query (note the test system used was on Linux using asmlib):
sys@+ASM1> select failgroup,disk_number,path from v$asm_disk where GROUP_NUMBER=1 and DISK_NUMBER in (0,24);
---------- ----------- --------------------
4.We can now confirm with OS commands that the mapping is correct. ‘dd’ allows the sysadmin to read the disks directly (bs=1M is the block size, while skip=176 means that the command starts reading at the offset 176M) . Using the disk name found in step 3 (only disk 0 demonstrated here) and the offsets found in step 2 we can confirm that the spfile data is at the expected physical location.
Putin si Medvedev stau de vorba.
- Trebuie sa desfiintam fusurile astea orare, creeaza numai probleme, spune Putin.
- De ce? - intreaba Medvedev
- Sun la Beijing sa-i felicit de ziua nationala, si-mi spun ca e maine , sun la Varsovia sa exprim condoleante si-mi spun ca avionul inca n-a decolat..
