Log Stream Guidelines

Defining log streams requires that you follow these guidelines:

SMS must manage your log stream data sets.
The SMS data class must support data compression.
Observe the log stream naming conventions.
Note: If you are upgrading and already have log streams defined, you can reuse those log streams.
Use the available log data types.
The available log data types are as follows:

ADTT

Indicates Audit Event records

IMRS

Indicates IMS region summary records

IMTR

Indicates IMS transaction records

MQHR

Indicates MQ historic requests

PLOT

Indicates historical plot records

SMFD

Indicates SMF data records

TRAN

Indicates CICS detailed transaction records

TSUM

Indicates CICS transaction summary records

SYSD

Indicates CICS system interval data records

XLOG

Indicates exception records for all components

Note: Although multiple log data types can share a log stream, we do not recommend sharing log streams that contain the SMFD and TRAN data types. The volume of data records being written to these logs is much greater than the volume being written to the other types.
Observe the LOGSTREAM description.
The LOGSTREAM description is 16 characters and cannot contain blanks.
