, enter the LRU list, and if you still cannot get to chunk, allocate from the remaining inner of the shared pool. If the cursor reaches the size standard of the _shared_pool_reserved_min_alloc implied parameter (4400 in 11.2.0.4), the chunk is allocated from the retention pool, and if the assignment chunk fails, the error: ORA-04031. If the bucket list is too long or the fragment is severe, latch:shared pool contention is generated.2. After assigning

Ubuntu startup failure! For help! Online, etc! -- Linux general technology-Linux technology and application information. For details, refer to the following section. I have a ubuntu-7.10-desktop-i386.iso. .
Prompt me when installing kernel panic-not syncing: IO-APIC + timer doesn't work! Boot with apic = debug and send a report. Then try booting with the 'noapi' option.
Then I installed it with the noapic parameter in F6, and the installation was successful.
I thought it was okay. But whe

traffic is still unable to withstand?To do these can already withstand very large traffic, but the business may continue to develop, can not withstand how to do?One of the first principles is that there is no distributed operation, the best way is single point, queued processing.second , the single point concurrency is too large, using the appropriate way to split the granularity of the lock; for example, product December, add a September period, June period and so on. For example, to increase
