In the current release the pre-formatted D OMVS options available through the Commands menu are:
(Blank), S or Summary |
Summary status information for all UNIX-based file systems, processes, servers and current parmlib settings. |
ASID or A |
Displays detailed information for the specific Address Space ID (ASID) or ALL ASIDs, depending on the parameter value specified. The ASID parameter is a required parameter. It can either be ALL or a specific ASID hexadecimal number, usually determined with an MVS D A command. This parameter is required. |
CINET or CI |
Displays the current Common Inet (CINET) Routing status information. The CINET Pre-Router process is used to link with TCP/IP for data transport over network routes. The CI parameter is a required parameter. It can either be ALL or a specific ‘tpname’ (transport provider name) as determined by values specified in the BPXPRMxx profile or by the SETOMVS command. |
FILE or F |
Displays a current list of Hierarchical File Structure (HFS) systems in use by USS as well as their current status. |
LIMITS or L |
Displays all the current system-wide USS parmlib value settings in place. This includes current system usage and high-water mark values. |
L,PID |
Provides current LIMIT values only for the specific active Process ID (PID). This includes current system usage and high-water mark values. A specific Process ID number must be entered for the PID field. This is a required value. |
OPTIONS or O |
Displays all current option settings as specified either during OMVS initialization using the BPXPRMxx parmlib member and/or settings that may have been dynamically altered via a SETOMVS command. |
PID |
Provides detailed thread information and current status for the Process ID (PID) specified by the required decimal value. A specific Process ID number must be entered for the PID field. This is a required value. |
PFS or P |
Displays information about all the currently configured USS Physical File System(s), either as an internal function of USS, as specified during OMVS initialization using the BPXPRMxx parmlib member, and/or as settings that have been recently altered via a SETOMVS command. This is not restricted to commonly recognized File Systems, such as HFS, but will also include application support processes, such as UNIX Affinity (local-based) sockets process, and the INET Affinity (network or remote server-based) sockets process. In the resulting display, these application support processes are labeled as PFS Types of UDS and TCP, respectively. There are some critical socket usage values you should watch carefully for these two important PFS types, including the MAXSOCK, OPNSOCK and HIGHUSED values. |
VSERVER or V |
Displays process details on all defined servers that utilize the Virtual File System (VFS) callable API services. Typically this could include BPXOINIT itself, or other defined servers, including web-based servers. |
U |
Lists process information for any active processes owned by the specified TSO/E user ID. This display might be utilized to determine which processes may have to be canceled when a user is reporting USS task processing problems. You should be aware that subsequent MVS cancellation of the TSO/E user ID may also be necessary in those situations. A specific TSO/E User ID must be entered for the U field. This is a required field. |
To use the D OMVS command under the Expert-Assist Interface, perform the following steps:
1. From the Commands main menu, click the D OMVS hyperlink under USS Command.
2. The D OMVS Command screen appears:
Figure 162. D OMVS Command screen
3. From the D OMVS menu, select one of the D OMVS commands. Some D OMVS commands require additional parameters.
These commands are:
D OMVS,A=ALL
or |
The Address Space ID field is required. You can only specify a hexadecimal Address Space ID (ASID). |
D OMVS,CI=ALL
or
|
The Transporter Provider Name is required. You can specify either ALL or a specific active ‘tpname’ (transport name provider). |
DOMVS,LPID=pid |
The Process ID is required You must specify the decimal PID value assigned for a currently active Process ID (PID) in order to accurately display all the current limits for that Process ID. |
D OMVS,PID=pid |
The Process ID is required. You must specify the decimal PID value assigned for a currently active Process ID (PID) in order to accurately display all the current thread information for the Process ID. |
D OMVS,U=userid |
The TSO/E User ID is required. You must specify a currently active TSO/E user ID name or value in order to accurately display the current status of all USS processes associated with that TSO/E user ID. |
4. When you are ready, click Submit to issue the command. The D OMVS Results screen appears. The D OMVS Results screen below displays if the user selected the DOMVS Summary Information command:
