Explanation
A QUERY SETSYS
command was issued and the setting of the EXTENDEDTTOC parameter of
the SETSYS command is returned in this message. The following are
the possible settings of the EXTENDEDTTOC parameter:
- EXTENDEDTTOC=Y
- EXTENDEDTTOC Y - Indicates that
the installation specified SETSYS EXTENDEDTTOC(Y) and that the OCDS
has been defined with a record size of 6144 bytes and can contain
up to 106 data set entries. In this case, DFSMShsm can write up to 1,060,000
data sets per volume. Any TTOC record written for new DFSMShsm tape
volume allocations while this value is in effect will contain 106
entries. Any tape volumes that were originally written or allocated
when this value was not in effect are limited to 33 data set entries.
- EXTENDEDTTOC=N
- EXTENDEDTTOC N - Indicates
that the installation specified SETSYS EXTENDEDTTOC(N). In this case, DFSMShsm can
write up to 330,000 data sets per volume. Any TTOC record written
for new DFSMShsm tape
volume allocations while this value is in effect will contain 33 entries.
Any tape volumes that were originally written or allocated when EXTENDEDTTOC(Y)
was in effect will still allow up to 106 data set entries.
System action
DFSMShsm processing continues.
