MODIFY-COSMOS-PARAMETER

Statements for SM2 administrators

BUFFER-SIZE = *UNCHANGED

The currently speciﬁed number of pages per buffer is not changed.

BUFFER-SIZE = <integer 1..7>

Buffers of the speciﬁed size (number of pages) are created.

NUMBER-OF-BUFFERS =

Speciﬁes the number of buffers.

NUMBER-OF-BUFFERS = *UNCHANGED

The currently speciﬁed number of buffers is not changed.

NUMBER-OF-BUFFERS = <integer 2..128>

COSMOS creates the speciﬁed number of buffers for writing events.

ADDITIONAL-INFO =

Speciﬁes additional data to be recorded.

ADDITIONAL-INFO = *UNCHANGED

The existing data speciﬁed for ADDITIONAL-INFO is not changed.

ADDITIONAL-INFO = *NONE

No additional data is recorded.

ADDITIONAL-INFO = *CONFIGURATION

The conﬁguration at the start of monitoring is also recorded.

ADDITIONAL-INFO = *VM2000(...)

The VM2000 events are also recorded. For this purpose, they must be explicitly opened (ADD-COSMOS-EVENT statement).

FILE-NAME = <ﬁlename 1..54 without-gen-vers>

Speciﬁes the name of the ﬁle to which the VM2000 events are written.

OUTPUT =

Speciﬁes how the COSMOS output ﬁles are written.

OUTPUT = *UNCHANGED

The currently speciﬁed value for OUTPUT is not changed.

OUTPUT = *DISK(...)

The COSMOS monitoring data is written sequentially to the ﬁles on hard disk; i.e. there is a write task for each output ﬁle. If a monitoring data buffer is full, a write task is activated that writes the buffer to the corresponding ﬁle.

FILE-NAME = list-poss(16): <ﬁlename 1..54 without-gen-vers>

Speciﬁes the ﬁle(s) to which the COSMOS monitored data is written.
