IZUSVR reference information
The following parameters are supported for use in the IZUSVR1 procedure.
- ROOT='directory-path'
- z/OSMF root code directory path. This value cannot be changed.
Default:
/usr/lpp/zosmf
- WLPDIR='directory-path'
- WebSphere Liberty server code path. The directory path must:
- Be a valid z/OS UNIX path name
- Be a full or absolute path name
- Be enclosed in quotation marks
- Begin with a forward slash ('/').
Default:/usr/lpp/zosmf/liberty
- OUTCLS='output-class'
- Suitable output class for writing system output. By default, the z/OSMF procedures use output
class
*
.The value must be in quotation marks.
Default:*
- USERDIR='directory-path'
- z/OSMF data directory path. By default, the IZUSVR1 procedure uses the
directory /global/zosmf. If your installation configured z/OSMF to use
another path for the data directory, specify that value here, for example:
USERDIR='/the/new/config/dir'.The directory path must:
- Be a valid z/OS UNIX path name
- Be a full or absolute path name
- Be enclosed in quotation marks
- Begin with a forward slash ('/').
Default:/global/zosmf
- TRACE='Y | N'
- Enables tracing for configuration-time errors, such as parmlib parsing errors. The error data is
written to the server job log. Use this option only at the direction of IBM Support.Default:
N
- IZUPRM=(PREV|SYSPARM|NONE|xx|(xx,...,zz))
-
The following values are valid:
- PREV
- Use the IZUPRMxx suffixes, if any were used by the previous instance of z/OSMF within the
current IPL. IZUPRM='PREV' is used as the default in the standard IZUSVR1 procedure. IZUPRM='PREV'
behaves like IZUPRM='SYSPARM' when the system encounters it during the initial IPL time (the first
use of the IZUSVR1 procedure) because there is no previous instance of z/OSMF to use.
This setting is not valid if the SERVER parameter is set to
STANDALONE
. - SYSPARM
- Use the IZUPRMxx suffixes that are specified on the IZU system parameter in IEASYSxx.
This setting is not valid if the SERVER parameter is set to
STANDALONE
. - NONE
- No parmlib members are specified and the z/OSMF defaults are used. For the default values, refer to the parameter descriptions in IZUPRMxx reference information.
- xx|(xx,...,zz)
- Specify the specific suffixes for the IZUPRMxx parmlib member or members that you want the procedure to use. If you specify a suffix, the member must exist in your parmlib concatenation. Otherwise, the procedure cannot be started. Multiple suffixes must be enclosed in parentheses.
The following syntax forms are valid:IZUPRM=PREV
IZUPRM=SYSPARM
IZUPRM=(xx,yy,zz)
IZUPRM=xx
IZUPRM=NONE
Note: The IZUPRMxx suffixes you specify, explicitly or implicitly, in the IZUPRM parameter of the procedure override any suffixes that are specified by using the IZU system parameter in IEASYSxx.Default:PREV
- SERVER=(AUTOSTART|STANDALONE)
- Indicates the start-up behavior of the z/OSMF server, as follows:
- AUTOSTART
- The z/OSMF server can be started automatically during system IPL. To do so, the system uses the started procedures that you identify on the SERVER_PROC and ANGEL_PROC statements in the active IZUPRMxx parmlib member for this system or uses their defaults. It is also possible to start the server manually, by using the START command, if no other z/OSMF server is active in the system's AUTOSTART group.
- STANDALONE
- The system does not start the z/OSMF server automatically. It can be
started manually by using the START operator command or by automation. The
system uses the started procedures that you identify on the SERVER_PROC and ANGEL_PROC statements in
the active IZUPRMxx parmlib member for this system or uses their defaults.
- If you choose not to autostart the z/OSMF server, you can use a started procedure similar to IZUSVR2 in SYS1.SAMPLIB for starting the z/OSMF server manually.
Default:AUTOSTART
- IZUMEM='maxmemlimit | NOLIMIT'
- Maximum amount (maxmemlimit) of usable, above-the-bar, virtual storage for
the z/OSMF server address space. This value can be expressed in megabytes (M), gigabytes (G),
terabytes (T), or petabytes (P). nnnnn can be a value 0 - 99999, with a maximum
value of 16384P. By default, the limit is 4 gigabytes (4G).Observe the following considerations:
- The amount of virtual memory that you request above 4G by using IZUMEM can be reduced by an SMFLIMxx or SMFPRMxx member of parmlib, or by an IEFUSI installation exit that lowers the memory limit for the IZUSVR1 started task.
- To indicate no limit to the amount of above-the-bar virtual storage, specify
NOLIMIT
.
Default:4G
