Neoview Command Interface (NCI) Guide (R2.5)

• If the statistics attribute exists, this command modifies it according to the new values.
• If the statistics attribute does not exist, this command inserts the new values.
Example
This command turns ALLSTAT on for the DDLTestDS data source:
SQL>alter ds DDLTestDS, allstat on;
ALTER DS TRACE Command
The ALTER DS TRACE command changes the tracing flag for the specified data source running
in an NDCS service.
Syntax
ALTER DS data-source-name, SERVICE $service-name, TRACE {ON | OFF}
data-source-name
is the name of the data source. data-source-name is case-sensitive and cannot be the
asterisk (*) wild card.
SERVICE $service-name
is the name of the association server of the NDCS service in which the data source is running.
TRACE {ON | OFF}
turns the tracing flag of the data source on or off.
Considerations
• To run this command in SQL mode, you must first run the CMDOPEN command. This
command does not run in CS mode.
• The command requires an SQL terminator.
• Only users associated with roles that have OPERATOR privileges can execute this command.
For more information, see the “ADD USER Command” (page 158) or “ALTER USER
Command” (page 167).
• The wild card (*) is not supported for the data source name, and the data source name is
case-sensitive.
• The data source can be in any state when you change the tracing flag.
• Once tracing is enabled for a data source, all servers that can write to the EMS alternate
collector begin writing the input and output data for each function executed during the trace
period. The servers generate this data for each function:
— Session ID
— Component name
— Object reference
— Sequence number
— Input values to the function or output from the function
This data is stored in the EMS log in message 21034.
Example
This command turns on the tracing flag for the data source DDLTestDS running in the $MXOAS
service:
SQL>alter ds DDLTestDS, service $mxoas, trace on;
