IVT5532I

• This message is a line separator.

IVT5574I

• This message is issued when the DISPLAY CSMUSE command is entered with the POOL operand. The message group that follows this message displays storage usage summary of all buffers in use for the user-specified pool with the buffers in use by monitor ID and OWNERID. This message is a header message for a detailed display of CSM storage usage for the CSM storage pool specified by the POOL operand of the Display CSMUSE command. It displays the user data value and history of the monitor ID.

IVT5576I

• This is the header message for the information displayed in the IVT5577I messages that follow.

IVT5577I

• This message displays the users of CSM storage, by monitor ID and OWNERID, that have allocated the largest amount of storage for a pool. The message can be repeated up to four times.
• amount is the total amount of CSM storage allocated to the monitor ID and OWNERID. The value is expressed in either megabytes (M) or kilobytes (K).
• monitorid is the identifier of the component of z/OS® Communications Server using the CSM buffer storage. It can be used by z/OS Communications Server service to diagnose CSM storage problems. The monitor function of CSM allows the operator to track the CSM buffer storage. If the CSM buffer is used by z/OS Communications Server, it will also have an owning component in z/OS Communications Server. This is the unique identifier of the component. See the z/OS Communications Server: IP and SNA Codes for the complete description of Monitor IDs.
• ownerid (OWNERID) is the owning address space identifier (ASID) for this CSM buffer storage and it is a hexadecimal value in the range of 0000 - 7FFF.
• jobname is the name of the job associated with the OWNERID. If jobname cannot be determined, this field contains ***NA***.

IVT5579I

• This is the header message for the detail information displayed in the IVT5580I messages that follow.
• mid is the current monitor ID of the buffers with the user data fields and monitor history displayed in the messages that follow.

IVT5580I

• This message displays the detailed user information and monitor ID history for a buffer in a CSM storage pool. It can be repeated up to four times.
• usecount is the number of primary buffers plus the images of buffers associated with the displayed user data field and monitor ID history for the monitor ID specified in the preceding IVT5579I message.
• userdata is the user data field associated with this buffer by the monitor identified by the monitor ID specified in the preceding IVT5579I message. The user data field allows IBM® service to correlate the current usage and history to a specific resource, such as a device, connection, route, and so on. This is a hexadecimal value.
• monitorhistory is a word containing the monitor ID history for a buffer in CSM storage. The first 3 bytes are the previous monitor IDs and the last byte is the current monitor ID. This is a hexadecimal value.

IVT5584I

• This message displays detail information about a CSM storage pool.
• poolname is the CSM pool. CSM pool names are as follows:

  4KECSA

  4KB buffer size ECSA storage pool

  16KECSA

  16KB buffer size ECSA storage pool

  32KECSA

  32KB buffer size ECSA storage pool

  60KDS

  60KB buffer size data space storage pool

  180KDS

  180KB buffer size data space storage pool

  4KDS64

  4KB buffer size data space backed by 64-bit real storage pool

  16KDS64

  16KB buffer size data space backed by 64-bit real storage pool

  32KDS64

  32KB buffer size data space backed by 64-bit real storage pool

  60KDS64

  60KB buffer size data space backed by 64-bit real storage pool

  180KDS64

• stoinuse is the total amount of storage in use in the pool. The value is expressed in either megabytes (M) or kilobytes (K).

IVT5585I

• This message displays the total amount of storage listed in the IVT5577I messages for the storage pool.
• poolname is the CSM pool. The CSM pool names are listed under the message IVT5575I.
• totamount is the total of the amount of storage displayed by all IVT5577I messages of the pool.
