The functions “importing” and “exporting” of public volumes (pubsets) and catalogs are initiated by means of the IMPORT-PUBSET and EXPORT-PUBSET commands by privileged users (see ). In this case a separate job is created for the required processing. The processing status can be monitored by means of job variables. Only the status indicator is supplied with values.
Information on the effects in an MSCF multiprocessor network can be found in the manual “HIPLEX MSCF” [ 8].
Status values for IMPORT-PUBSET:
Value | Meaning/reason for setting the value |
$I | Import job initiated successfully. |
$R | Pubset imported successfully. |
$A | Import terminated abnormally. |
$W | For import of a shared pubset, the processor waits for confirmation by the master processor. |
Table 17: Status values for IMPORT-PUBSET
Status values for EXPORT-PUBSET: Monitoring for shared pubset operation
Value | Meaning/reason for setting the value |
$E | Export job started successfully. |
$T | Export of a pubset completed successfully. |
$A | Export terminated abnormally or with CANCEL-PUBSET-EXPORT. |
Table 18: Status values for EXPORT-PUBSET
Using HIPLEX MSCF allows concurrent shared access to a pubset across a number of computers. One of the network partners (“sharers”) is nominated as the owner processor (“master”) of this shareable pubset, and becomes responsible for the administrative tasks of the network.
On the home pubset of each sharer there is a shared pubset-specific job monitoring job variable for each shared pubset; this is created when the pubset is imported (if it does not already exist).
This monitoring job variable can take on the following status values:
Value | Meaning/reason for setting the value |
$R | Shared pubset available. Master switchover successfully completed. |
$T | Shared pubset is no longer monitored; it will be or has already been exported. |
$A | Master switchover terminated abnormally, e.g. because master has crashed and nomination of a new master from the slave processors has failed. |
$C | Due to master crashing or being shut down, a master switchover has been performed on the public volume. |
