The system configuration options member is used to set configuration options during the initialization of CA SYSVIEW. The system configuration options member is located in the concatenation of the system parmlib data sets.
Example: SYS1.PARMLIB
Assign a subsystem ID to each instance or installation of CA SYSVIEW within a z/OS system or LPAR.
The four-character CA SYSVIEW subsystem ID (SSID) is used to name the System Configuration Options system parmlib member.
Member name = GSVXssid
The first four characters of the member name are always GSVX.
For example:
SYSVIEW subsystem ID = GSVX Member name = GSVXGSVX
The default SYSVIEW subsystem ID is GSVX.
Multiple instances of CA SYSVIEW can be installed on a single z/OS system. These instances of CA SYSVIEW can be of the same or different release levels.
If multiple instances of CA SYSVIEW are installed with the same subsystem ID, those instances specify their system configuration options in the same SYS1.PARMLIBs member GSVXssid.
Separate the options by release by enclosing the options for each instance within the following structure.
Those options that are not unique to an instance can be shared across multiple instances and do not need to be within an ")IF" statement.
Example 1:
)IF RELEASE=13.9 option1 option2 )ENDIF
)IF RELEASE=13.7 option1 option2 )ENDIF )IF RELEASE=13.5 option1 option2 )ENDIF )IF RELEASE=rr.m option1 option2 )ENDIF
Example 2:
)IF RELEASE=13.9 )INCLUDE mbr139 )ENDIF
)IF RELEASE=13.7 )INCLUDE mbr137 )ENDIF )IF RELEASE=13.5 )INCLUDE mbr135 )ENDIF
In releases before CA SYSVIEW r13.5, the SYSVIEW GEN modules specified the system configuration options. The GEN modules are no longer used.
A CA SYSVIEW installation is comprised of several types of libraries or data sets designed to contain a specific type of data. This library is referred to as a library type(libtype).
A library type can consist of multiple data sets. These data sets dynamically concatenate when a read request is made for the specified library type.
Only one data set can be defined for each data set type. Therefore, a maximum of three data sets can be concatenated.
If defined, the data sets are concatenated in the following order:
libtype DD DISP=SHR,DSN=user.data.set DD DISP=SHR,DSN=site.data.set DD DISP=SHR,DSN=system.data.set
The possible data set types are:
The optional user-defined data sets contain definitions or overrides to site or system definitions.
The users define and maintain the user data set names in their CA SYSVIEW profile.
The optional site defined data sets contain definitions or overrides to system definitions.
The site data set names are defined in the CA SYSVIEW System Configuration Options member: GSVXGSVX
The system configuration options member must be located in the concatenation of the z/OS system parmlib data sets.
Example: SYS1.PARMLIB
The required system defined data sets contain definitions or configuration options. The set of system data sets contains the original members the product installation delivered. The system data set names are defined in the CA SYSVIEW System Configuration Options member: GSVXGSVX
The system configuration options member must be located in the concatenation of the z/OS system parmlib data sets.
Example: SYS1.PARMLIB

CA SYSVIEW has over 1000 variable metrics that can be used to monitor system resources or resources from subsystem components such as:
CA SYSVIEW typically monitors several 100,000 resources. You can create exception alerts for each resource or metric.
The command ALERTSUM is available to summarize and organize the monitoring of resources and metrics.
Example commands and displays:
The monitored exception alerts can be summarized at several different levels:
Displays a single summary data row for each owner.
When the owner has multiple child instances, the alert information is rolled-up into the owner summary data row.
Displays a single summary data row for each owner.
Displays a single data row for each resource summary group that is associated with the owner.
If the owner has multiple child instances, the alert information is rolled-up into the owner summary data row and the summary resource data rows.
Displays a single summary data row for each owner.
Displays a single data row for each instance that summarizes any associated resource summary groups that are associated with the owner.
Displays a single summary data row for each owner.
Displays a single data row for each instance that summarized any associated resource data rows.
Displays a data row for each resource that is associated with the instance.
CA SYSVIEW maintains historical collection data for online viewing through MVS log streams.
Enhancements to the CA SYSVIEW log stream technology that is used to read and write from log streams provides the following benefits:
