@fuadar you can do ODA 2.2 with an existing 11.2.0.2 database; you just can't run both 11.2.0.2 and 11.2.0.3 before ODA 2.3 comes out

Back blogging

Why do we blog? I mean, one can understand if you are blogging on your company site. Answer seems to me like someone might hit upon this and be benefited. Even my little daughter might chance across this blog...when she's big enough like they show in this ad for Google. But foremost, is a primordial & basic impulse of expressing oneself.

Case in hand specifically is, there's a lot good information floating around via twitter.
This could be a permanent place to collect 'em.

So, I am back blogging.

A lovely and beautiful and slow and grey day

I know time will fly. Weeks and months roll on.

"Each day just goes so fast
I turn around , it's past
...
...
A lifetime is so short
A new one can't be bought"
         --- "Love you to", Beatles, The Revolver

We all wanted our workdays to be very short and weekends long.
We wanted to laze around at home and never wanted to come office.

It's strange that I want to come to my office each day and actually wish the day doesn't end so quickly.
I wish I had enjoyed my workplace more. Just 4 more days. Grey and beautiful. Hum of the datacenter seeping thru. On some brilliant days, the sunlight. Today, the greyness.

Time to go home.
But today is a beautiful long day.

Managing ASM Disk Discovery

Most of the times, when everything else fails we turn to setting ASM_DISKSTRING as '/dev/oracleasm/disks/*' and it is almost always guaranteed to work. But this way we know that the ASM Library is not used at all and disk discovery happens outside the Library. Not a good thing. This can be confirmed using kfod (kfod asm_diskstring=ORCL:* disks=all) . So, what should you tinker with then  to use the ASM Lib rather than the SYSTEM library, as shown by the LIBRARY field of v$asm_disk? When doing a migration, you may also get a HEADER_STATUS=UNKNOWN and the errors ORA-15032, ORA-15063 and ORA-15186.

Well, if you are using multipathing s/w, you got to let the disk discovery use just the pseudo-devices and not any of the many single devices (thru' many I/O paths) that form a single pseudo device. If you are using EMC with PowerPath, set it to emcpower. If you are using NetApp with DeviceMapper, set it to dm.
