IBM Tivoli NetView for z/OS Programming: Pipes - IBM notice

SQSELECT - Format a Query
DSIDB2MT task, ensure any SQL requests that do not specify which DB2 to
access are accessing the same DB2. A new parameter (SSIDssidname |*) on the
SQL stage defines whether a specific or the default DB2 is accessed. When an
SQL stage defines a subsystem to be accessed, that subsystem remains in effect
for that task until you reset it by using another SQL stage.
v The DSIDB2MT task must be started if you want to define a default DB2 for the
Tivoli NetView for z/OS address space. This task connects the Tivoli NetView
for z/OS system to a specific DB2 subsystem so that any task in the Tivoli
NetView for z/OS address space has access to DB2 unless the SQL stage
specifies otherwise.
– Running the RRS level of interfaces requires MVS system definitions.
– RRS requires a sysplex; this can be a single system monoplex.
– It does not require a coupling facility if RRS is installed with the DASD only
logging option. This requires a COUPLExx sysparm member which identifies
the COUPLE and LOGR data sets.
– Define CFRM data sets if you need them. RRS requires 4 logs and has an
additional optional one. They are an ARCHIVE, MAIN.UR, DELAYED.UR,
RESTART, and RM.DATA. The z/OS MVS Programming Resource Recovery
describes these logs.
– To enable the DASD only logging option, you might need to upgrade to
OS/390 Release 4 and apply the following APAR: OW30206, PTF # UW43930.
The upgrade to OS/390 requires an upgrade to VTAM Version 4 Release 4.
– To start RRS, you can add it to the COMMNDxx system parameter member
or add it to your automation.
SQSELECT formats a query to be displayed on a terminal. The filter takes a query
as the argument, describes the query, and formats the result. In the following
example, the first line of the response contains the names of the columns padded
with hyphens to their maximum length. The remaining lines represent the result of
the query.
The SSID DB2 option is supported for SQSELECT, which passes the value to the
underlying SQL stages for example:
SQSELECT (SSID DB2) project_name from projects
PROJECT_NAME---
BLUE MACHINE
GREEN MACHINE
ORANGE MACHINE
RED MACHINE
WHITE MACHINE
pipe SQL describe select salary, name from staff | console
484 DECIMAL 8,2 5 SALARY
449 VARCHAR 9 11 NAME
SQSELECT salary, name from staff where years is null
SALARY--- NAME-----
96808.30 GRUMPY
93504.60 BASHFUL
92954.75 SLEEPY
91508.60 DOPEY
