Select from V$SGA_TARGET_ADVICE fails on Oracle 10.2 for Linux. The error reported is about division by zero: SQL> select * from v$sga_target_advice; select * from v$sga_target_advice * ERROR at line 1: ORA-01476: divisor is equal to zero I discovered this by attempting to run STATSPACK. Of course, it bombed out with the same error. SGA parameters are like this: SQL> show parameter sga NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ lock_sga boolean FALSE pre_page_sga boolean FALSE sga_max_size big integer 400M sga_target big integer 352M Does anybody have any idea? Is this just one of the "features"? Statspack is fairly important tool and I'd hate to run a production system on something like this. The description of this table is here: V$SGA_TARGET_ADVICE V$SGA_TARGET_ADVICE provides information about the SGA_TARGET initialization parameter. Column Datatype Description SGA_SIZE NUMBER Size of the SGA SGA_SIZE_FACTOR NUMBER Ratio between the SGA_SIZE and the current size of the SGA ESTD_DB_TIME NUMBER Estimated DB_TIME for this SGA_SIZE ESTD_DB_TIME_FACTOR NUMBER Ratio between ESTD_DB_TIME and DB_TIME for the current size of the SGA ESTD_PHYSICAL_READS NUMBER Estimated number of physical reads This table contains two ratios and one of them must be zero for an almost inactive database like this one. Now I know why is 10.2 out only for Linux. -- http://www.mgogala.com -- //www.freelists.org/webpage/oracle-l
