CEMT INQUIRE DSAS

Displayed fields

CDSASIZE(value)

Displays the size, in bytes, of the CICS dynamic storage area (CDSA). CICS calculates and manages the size of this storage area automatically, within the overall limits specified for all the DSAs that reside below 16 MB (below the line).

DSALIMIT(value)

Displays the maximum amount of storage, as a total number of bytes, within which CICS can dynamically allocate storage for the four individual DSAs that reside below 16 MB (below the line). For more information, see DSALIM system initialization parameter.

Note: You can reset this value by overtyping it with a different value.

If DSALIMIT specifies a value lower than the current limit, CICS might not implement the new limit immediately, but attempts to do so over time as dynamic storage is freed in the individual DSAs.

ECDSASIZE(value)

Displays the size, in bytes, of the extended CICS dynamic storage area (ECDSA) above 16 MB but below 2 GB (above the line). CICS calculates and manages the size of this storage area automatically, within the overall limits specified for all the DSAs that reside above the line.

EDSALIMIT(value)

Displays the maximum amount of storage, as a total number of bytes, within which CICS can dynamically allocate storage for the individual DSAs that reside above 16 MB but below 2 GB (above the line). For more information, see EDSALIM system initialization parameter.

You can reset this value by overtyping it with a different value.

If EDSALIMIT specifies a value lower than the current limit, CICS might not implement the new limit immediately, but attempts to do so over time as dynamic storage is freed in the individual DSAs.

ERDSASIZE(value)

Displays the size, in bytes, of the extended read-only dynamic storage area (ERDSA) above 16 MB but below 2 GB (above the line). CICS calculates and manages the size of this storage area automatically, within the overall limits specified for all the DSAs that reside above the line.

ESDSASIZE(value)

Displays the size, in bytes, of the extended shared dynamic storage area (ESDSA) above 16 MB but below 2 GB (above the line). CICS calculates and manages the size of this storage area automatically, within the overall limits specified for all the DSAs that reside above the line.

ETDSASIZE(value)

Displays the size, in bytes, of the extended trusted dynamic storage area (ETDSA) above 16 MB but below 2 GB (above the line). CICS calculates and manages the size of this storage area automatically, within the overall limits specified for all the DSAs that reside above the line.

EUDSASIZE(value)

Displays the size, in bytes, of the extended user dynamic storage area (EUDSA) above 16 MB but below 2 GB (above the line). CICS calculates and manages the size of this storage area automatically, within the overall limits specified for all the DSAs that reside above the line.

GCDSASIZE(value)

Displays the size of the above-the-bar CICS dynamic storage area (GCDSA). The value is displayed in gigabytes followed by the letter G. CICS calculates and manages the size of this storage area automatically.

GSDSASIZE(value)

Displays the size of the above-the-bar shared dynamic storage area (GSDSA). The value is displayed in gigabytes followed by the letter G. CICS calculates and manages the size of this storage area automatically.

GUDSASIZE(value)

Displays the size of the above-the-bar user dynamic storage area (GUDSA). The value is displayed in gigabytes followed by the letter G. CICS calculates and manages the size of this storage area automatically.

MEMLIMIT(value)

Displays the limit of storage above the bar for use by the CICS region. The value is displayed in megabytes followed by the letter M, gigabytes followed by the letter G, or terabytes followed by the letter T. A value of NOLIMIT indicates that no limit is imposed on the amount of storage that the region can attempt to use.

RDSASIZE(value)

Displays the size, in bytes, of the read-only dynamic storage area (RDSA). CICS calculates and manages the size of this storage area automatically, within the overall limits specified for all the DSAs that reside below 16 MB (below the line).

SDSASIZE(value)

Displays the size, in bytes, of the shared dynamic storage area (SDSA). CICS calculates and manages the size of this storage area automatically, within the overall limits specified for all the DSAs that reside below 16 MB (below the line).

SOSABOVEBAR(value)

Displays whether CICS is short on storage in the dynamic storage areas above the bar.

NOTSOS: CICS is not short on storage in any of the dynamic storage areas above the bar.
SOS: CICS is short on storage in at least one of the dynamic storage areas above the bar.

SOSABOVELINE(value)

Displays whether CICS is short on storage in the dynamic storage areas above 16 MB but below 2 GB (above the line).

NOTSOS: CICS is not short on storage in any of the dynamic storage areas above 16 MB but below 2 GB.
SOS: CICS is short on storage in at least one of the dynamic storage areas above 16 MB but below 2 GB.

SOSBELOWLINE(value)

Displays whether CICS is short on storage in the dynamic storage areas below 16 MB (below the line).

NOTSOS: CICS is not short on storage in any of the dynamic storage areas below 16 MB.
SOS: CICS is short on storage in at least one of the dynamic storage areas below 16 MB.

UDSASIZE(value)

Displays the size, in bytes, of the user dynamic storage area (UDSA) below 16 MB (below the line).
