IVT5532I

• This message is a line separator.

IVT5572I

• This message is a header message for a summary of CSM storage usage for one or more storage pools that have buffers in use. The summary information shows storage usage by monitor ID and OWNERID.

IVT5575I

• This message displays summary information about a CSM storage pool. This is the first message of a subgroup of messages issued for each CSM storage pool. The subgroup of messages starting from IVT5575I through IVT5578I are for one 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

  60KECSA

  60KB buffer size ECSA storage pool

  180KECSA

  180KB buffer size ECSA storage pool

  4KDS

  4KB buffer size data space storage pool

  16KDS

  16KB buffer size data space storage pool

  32KDS

  32KB buffer size data space 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

  180KB buffer size data space backed by 64-bit real storage pool

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

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 that have allocated the largest amount of the storage for a pool by monitor ID and OWNERID. 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***.

IVT5578I

• This message displays the total amount of storage listed in the IVT5577I messages for one storage pool.
• poolname is the CSM pool. The CSM pool names are listed under the message IVT5575I.
• number is the number of users using CSM storage displayed by the IVT5577I messages.
• totamount is the sum of amount displayed in the IVT5577I messages issued with this group.
