Specifies the maximum sizes of the corresponding output files used by the data extraction facility.
There are eight options: TEMP_EXTRACT_SIZE1 through TEMP_EXTRACT_SIZE8.
TEMP_EXTRACT_SIZE1 through TEMP_EXTRACT_SIZE8 are used to specify the maximum sizes of the corresponding output files used by the data extraction facility. TEMP_EXTRACT_SIZE1 specifies the maximum size of the output file specified by TEMP_EXTRACT_NAME1, TEMP_EXTRACT_SIZE2 specifies the maximum size of the output file specified by TEMP_EXTRACT_NAME2, and so on.
The default for the data extraction size options is 0. Sybase IQ converts this default to these values:
Device type |
Size |
|---|---|
Disk file |
AIX and HP-UX: 0 – 64GB Sun Solaris & Linux: 0 – 512GB Windows: 0 – 128GB |
Tape* |
524288KB (0.5GB) |
Other |
9007199254740992KB (8192 Petabytes “unlimited”) |
*Tape devices currently are not supported.
When large file systems, such as JFS2, support file size larger than the default value, set TEMP_EXTRACT_SIZEn to the value that the file system allows. For example, to support lTB set option:
TEMP_EXTRACT_SIZE1 = 1073741824 KB
If you are extracting to a single disk file or a single named pipe, leave the options TEMP_EXTRACT_NAME2 through TEMP_EXTRACT_NAME8 and TEMP_EXTRACT_SIZE1 through TEMP_EXTRACT_SIZE8 at their default values.
The TEMP_EXTRACT_SIZEn options are not compatible with TEMP_EXTRACT_APPEND. If you try to restrict the size of the extract append output file, Sybase IQ reports an error.
