ORA-01114 [message #302265]

I am running Oracle Analyze with the command below against 20 tables which has about 30000000 to 45000000 rows for each table.

dbms_stats.gather_table_stats (ownname=>'USER_1',tabname=>'TABLE_1',CASCADE=>FALSE,estimate_percent=>100);

However, I am getting the error below for some tables (some are succeeding) even though there is enough disk space and low CPU/Memory usage :

ORA-01114: IO error writing block to file %s (block # %s)

Unable to dump event group - SGA not mapped

(Extract from trace file)

Could someone tell me how I can fix this problem?

I guess that the error is occurring due to the lack of free space in the SGA but is there a way to check the SGA usage dynamically?

The below is the system I am using :

Oracle 10.2.0.3.0
OS : HP-UX 11.11
CPU : 875MHz x 12
Memory : 24GB

Any help will be greatly appreciated.

Steve

ORA-01114: IO error writing block to file %s (block # %s)
 *Cause:  The device on which the file resides is probably offline. If the
          file is a temporary file, then it is also possible that the device
          has run out of space. This could happen because disk space of
          temporary files is not necessarily allocated at file creation time.
 *Action: Restore access to the device or remove unnecessary files to free
          up space.

"SGA not mapped" are internal errors, no relation with a classic lack of free memory, maybe a memory leak.
I think you have to call Oracle support.

>> IO error writing block to file %s (block # %s)
Could you also check which particular tablespace/datafile is in question here?
I have seen ORA-01114 could be misleading sometimes.
Could you enable a 10046, level 12 trace and try the same
statement again to see in which stage it exactly happened?
