		<description><![CDATA[I was searching for a fancy function yet the good old addition is a fine solution.
I&#039;ve updated the script. Calculate the total ash seconds for the machine and divide the numbers by it to show the percantice.
Next step will be to get the top 10 or 20 sqls and sum the remaining as the rest.
thanks.]]></description>

		<description><![CDATA[Hi,
What about expdp via dblink on partitions and subpartitions?
It gave me below errors :- 

ORA-39203 -- while trying OWER.TABLE_NAME:PART_NAME

and 

ORA-14100: partition extended table name cannot refer to a remote object
While trying to use query=&quot;where [partition_column] &quot;  in order to avoid above error.

Normal Export works perfect with user/passwd@ but wonder why expdp has so many  constraints.]]></description>

		<description><![CDATA[Merhaba Ferhat,

Biz de aynı problemle karşılaşmıştık. FR Exadata&#039;nın bir disk&#039;i sarı ışık yakmıştı. CELLCLI bize predictive failue veriyordu. Error count&#039;ta artıyordu. Metalink&#039;te bu konuyla direkt ilgili bir not var ve yeniden celldisk, griddisk ve asm disk ekleme yapmadan sorun giderilebiliyor. ASM üzerinden ilgili diski drop ettikten sonra fiziksel olarak çıkartıp yenisini ekliyorsun. Bu arada power limit yüksek olursa o kadar hızlı rebalancing oluyor. Disk drop edildiği zaman temiz olanını yerleştiriyorsun. Cell otomatik olarak görüyor ve giriş tarihini yeni fiziksel disk için tanımlıyor. Ardından ASM&#039;ye gösteriyorsun. Normal şartlar altında böyle ilerliyor ama bazen cell ve griddisk olarak tanımlaman da gerekebiliyor. Bunda da zaten bir sakınca yok.

Paylaşım için teşekkürler, elinize sağlık.
