You are configuring the PROD database to use an internal tuning algorithm to monitor the performance of the workload. To achieve this configuration， you specify the following parameter settings in the SPFILE： SGA_TARGET = 512M SHARED_POOL_SIZE = 256M Which two statements are true when modifying the SHARED_POOL_SIZE initialization parameter in the SPFILE？ （） Modifying the SHARED_POOL_SIZE initialization parameter cannot be accomplished if the SGA_TARGET initialization parameter is set to a non-zero value.。 Modifying the value of the SHARED_POOL_SIZE initialization parameter to zero is not allowed if the SGA_TARGET initialization parameter is set to a nonzero value.。 Increasing the value of the SHARED_POOL_SIZE initialization parameter does not increase the shared pool component size. It sets the lower limit for the size of this component.。 Decreasing the value of the SHARED_POOL_SIZE initialization parameter does not reduce the size of the shared pool component immediately. It sets the lower limit for the size of this component.。 Increasing the value of the SHARED_POOL_SIZE initialization parameter immediately increases the shared pool component to the desired size by reallocating the additional memory from the auto-tuned memory components.。 Decreasing the value of the SHARED_POOL_SIZE initialization parameter immediately shrinks the shared pool component to the desired size while reallocating the released memory to the memory components that are not auto-tuned.。
A Dell customer decided to use IBM Director and xSeries to manage their servers. They purchased 10 IBM x336 servers and they already have 75 various Dell servers. Which TWO steps need to be verified to be able to manage the mixed environment with IBM Director？（） Verify that the Dell systems have TCP/IP enabled。 Verify that the systems are running the IBM Director Agent。 Verify that the managed systems are SMBIOS 2.1 and WfM 2.0 compliant。 Verify that the Dell systems have at least a 1GB of memory installed。 Install an SNMP agent on the Dell systems as IBM Director cannot manage Industry Standard non-IBM server。
