Ora-01115: Io Error Reading Block From File 5
a dbms_stats job with default_degree and I'm getting a ORA-01115 error. This is an 8 CPU server running 10g on HP/UX. BEGIN DBMS_STATS.GATHER_DICTIONARY_STATS (ESTIMATE_PERCENT => DBMS_STATS.AUTO_SAMPLE_SIZE, METHOD_OPT => 'FOR ALL ora-01115 ora-01110 ora-27072 COLUMNS SIZE AUTO', DEGREE => DBMS_STATS.DEFAULT_DEGREE, GRANULARITY => 'ALL', CASCADE => TRUE, OPTIONS => 'GATHER', NO_INVALIDATE => FALSE); END;*ERROR at line 1:ORA-12801: error signaled in parallel query server P012ORA-01115: IO error reading block from file 22 (block # 969)ORA-27072: File I/O error I only have 8 CPU's and I don't understand why Oracle fired-off 12 parallel query slaves (parallel query ora-27070: async read/write failed server P012). What causes this ORA-01115 error in automatic parallel query? When I manually reduce the parallelism, it runs fine! Answer: The docs note this about the ORA-01115 error, the ORA-01115 is a transient I/O error not related to block corruption: ORA-01115: IO error reading block from file string (block # string) Cause: Device on which the file resides is probably offlineAction: Restore access to the device Using 12 parallel query slaves probably not optimal for an 8 CPU server, and Oracle may have over-estimated the optimal degree of parallelism. Here are the rules I use for optimizing the degree of parallelism. Also note that using parallel automatic tuning can HURT your performance, and I prefer to set parallelism manually, on a case-by-case basis. I suspect that your error is caused by firing off too many parallel query slaves, but you should also check for a bug on MOSC. You can pinpoint the tablespace and segment for an ORA-01444 error by plugging-in the file_id and block_id into this query on dba_extents: select owner,tablespace_name, segment_type, segment_name from dba_extentswhere file_id = 1030and block_id = 602122; In some cases, the ORA-01114 error occurs w
