Creating an output group
To create an output group
- On the option set’s panel (see Creating a DOMPLEX option set), expand Output Groups.
- On the Output Groups line, overtype I on the minus sign (-) and press Enter.
Type I on the - sign
Type R to replicate an existing Output Group and then type over the name with a new name
Type E to define a new instance using the default values.
The new output group is displayed at the top of the list and is by default is numbered 001. However you can use any 3-digit number within the range. Each output group must have a unique number within the DOMPLEX set.
Tip
This step inserts a completely new output group. If you prefer repeating an existing output group, type R on the plus sign (+) next to that output group and press Enter.
Doing so copies the new group under the original group and uses the same group number for both. Change the number for the new group to be unique.
- To edit the parameters for the new output group, expand its group number.
- In the Output Groups section, complete the following fields:
Field
Description
OutGp
(Group Number)
Specify the number of the output group.
Valid values are 001 through 256.
DCID
(Data Collector SSID)
Specify the subsystem ID of the Data Collector that owns the output group.
DspSize
(Data space size)
The recommended size depends on the types of data assigned to this group and the load expected for all types combined.
The size is specified in megabytes in the range 0 to 2000. A value of zero causes all IFCIDs assigned to this group to be immediately discarded.
Note
The sum of data space for all output groups assigned to the same data collector cannot exceed 2000MB.
- Expand the Data Classes section to specify the IFCIDs that this output group captures and stores.

- Expand the NGL LOGSET Parameters section to specify the Next Generation Logger (NGL) LOGSET parameters for the output group. See the following table for a description of the NGL LOGSET parameters.
Parameter
Description
Logset Compression
Specify how to compress the log file data or to disable compression:
LOW (default), is considered the optimal balance of compression and CPU usage
HIGH saves more DASD space but use significantly more CPU (including zIIP usage where available)
NO disables compression, saving CPU usage at the expense of DASD space
LOGSET time span
Specify the amount of time that you would like to have data kept in log files, in days (D), hours (H), or minutes (M). You can specify only one type. If you specify a number without a type, the value defaults to days.
If all of the log files become full in less time than this time span allows, more log files are allocated, up to the maximum allowed.
Max log buffers
Specify the maximum number of log I/O buffers to use. Valid values are 2 through 20.
Max read buffers
Specify the maximum number of read I/O buffers to use. Valid values are 2 through 99.
Deferred write time
Specify the maximum time delay before buffered records are written to the DASD log files. A shorter deferred time requires more write I/Os but means less vulnerability to data loss if an outage occurs. Valid values are 1 through 999 seconds.
Minimum log file data sets (LDS)
Specify the number of log file datasets that are allocated when the data collector starts. Valid values are 1 through 99.
Maximum log file data sets (LDS)
Specify the maximum number of log file datasets that can be allocated as needed to meet the LOGSET time span goal. Valid values are 1 through 99.
Space to allocate (per LDS)
Specify the total space used for each LOGFILE. Valid values are 1 through 9999 MB.
LDS Allocation Type
Specify the type of allocation parameters to be used.
SMS: DFSMS parameters are used and you must provide at least one of the SMS parameters (storage class, management class, data class)
VOL: you must provide a traditional VOLSER to indicate where the LOGFILE should be allocated.
NONE: you provide no allocation parameters and the system defaults are used
LDS Volume
(mandatory if you select type volume) Specify the volume for the LOGSET.
LDS DFSMS Data Class
(mandatory if you select type SMS) Specify the DFSMS data class for the LOGSET.
LDS DFSMS Management class
(mandatory if you select type SMS) Specify the DFSMS management class for the LOGSET.
LDS DFSMS Storage Class
(mandatory if you select type SMS) Specify the DFSMS storage class for the LOGSET.
LDS DSN prefix
Specify the DSN prefix for the LOGSET (log file) data sets.
Note
Supports system static and dynamic symbols
Enable Archiving
Specify Y to enable LOGSET data set archiving.
Archive Wait Time
Specify the maximum time in seconds to wait for an archive to finish before reusing a LOGFILE. Allowed values are 1-9999, with a default of 600.
Archive post processing job
(optional) Specify the data set that contains the job that will execute when the archive job is done.
Max days to keep archives
Specify the number of days to keep archive data sets. Valid values are 1 through 999 days, or 0 which indicates no limit.
Max number of archives to keep
Specify the number of archived data sets to keep. Valid values are 1 through 999 archives, or 0 which indicates no limit.
Max combined size of archives
Specify the total space used by all archive data sets. Valid values are 1 through 999999 MB, or 0 which indicates no limit.
Archive file allocation type
Specify the type of allocation parameters to be used.
SMS: DFSMS parameters are used and you must provide at least one of the following SMS parameters (storage class, management class, data class)
VOL: you must provide a traditional VOLSER to indicate where the LOGFILE should be allocated.
UNIT: Specify any valid unit name
NONE: you provide no allocation parameters and the system defaults are used
Archive Volume
(mandatory if you select type volume) Specify the volume for the LOGSET.
Archive Unit
(mandatory if you select type unit) Specify the unit for the LOGSET.
Archive DFSMS Data class
(mandatory if you select type SMS) Specify the volume for the archive.
Archive DFSMS Management class
(mandatory if you select type SMS) Specify the DFSMS management class for the archive.
Archive DFSMS Storage class
(mandatory if you select type SMS) Specify the DFSMS storage class for the archive.
Archive GDG
Specify Yes to configure the enabled DSN prefix (Archive DSN Prefix or the Alternate full archive DSN) as the base name for a generation data group. All members of the archive output data set are members of a generation data group (GDG).
Archive DSN prefix
(optional) Specify the DSN prefix for the archive. 1
Alternate full archive DSN
(optional) Specify the archive DSN. The product uses this value in place of the value defined as the Archive DSN prefix. You must ensure that the name is unique for each archive created. BMC suggests using date and time symbolics in the name. 1
Example
For example: BMCPERF.D&YYMMDD.T&HHMMSS
1 Supports system static and dynamic symbols
The Archive DSN prefix and Alternate full archive DSN are mutually exclusive. Specify a value for one or the other.

Comments
Hello,
Can you please add an information stating that the output from NGLARCH is equal to SMF records and can therefore be used as input for MVDB2 Report Writer DPRSMF. thanks Feli
Hi, Feli. Thanks for the suggestion! We are forwarding it to the writer who is in charge of the content.
Thanks Dottie
