Handling SMF Files
SQL/MX File Guidelines
Although you can use FUP commands to provide information about SQL/MX files,
the commands cannot manipulate or duplicate the SQL/MX files.
To display information for SQL/MX files, use the FUP FILES, FILENAMES, INFO,
LISTOPENS, and SUBVOLS commands.
The partition information for SQL/MX objects is displayed without the partition key.
The partition key information for SQL/MX objects is available from MXCI
SHOWDDL.
For compatibility with the FUP PURGE command, substitute the keyword PURGE
for DROP in the MXCI DROP utility.
Handling SMF Files
Storage Management Facility (SMF) provides location-independent naming capabilities
for Guardian files. FUP supports SMF commands by displaying information about files
on virtual disks and lets you specify physical volumes.
Unique Features of EKS Files
Enhanced Key-Sequenced Files (EKS) have the following unique features:
The primary partition does not store user data but instead stores the file metadata.
When creating an EKS file, the partial key of the first secondary partition must be
explicitly set to all zeros.
For example, SET PART(1,$FC11,16,16[0,0,0,0,0])
When creating an EKS file, the primary and secondary extent size of the primary
partition must be greater than or equal to 140 otherwise, the default value of 140 is
used.
When accessing the primary partition of an EKS file, in an unstructured mode,
reads on the file return FEEOF (1) and writes on the file return FEFILEFULL (45).
This is because the metadata stored in the primary partition cannot be accessed by
non-privileged applications.
