XCHECK command
Use the XCHECK command to invoke the Cross Check utility.
Operands
This section describes the operands that the XCHECK command can contain.
TYPE =
The TYPE= operand specifies the type of cross checking that you want to perform.
If the INDD= operand is specified, then it must refer to an ACB library. If the INDD= operand is specified, then it must refer to an ACB library.
Required or Optional | Required |
|---|---|
Synonyms | None |
Values | Valid values are listed in the TYPE= values table. |
Default value | None |
TYPE= values
TYPE value | Description |
|---|---|
ACB | When you specify TYPE=ACB, the utility checks the DMB and PSB members of the ACB library against the corresponding members of the DBD and PSB libraries. Required JCL statements include:
If you specify TYPE=ACB, the MBR= and MBRLIST= operands are ignored. |
DBD | When you specify TYPE=DBD, the utility checks each DBD load module that it finds in a DBD library to make sure that any DBD that it references is also in that same DBD library. Required JCL statements include:
|
PSB | When you specify TYPE=PSB, the utility checks each PSB load module that it finds in a PSB library to make sure that any DBD that it references is also in a DBD library. Required JCL statements include:
|
RECON | When you specify TYPE=RECON, the utility checks each DBD definition that it finds in a RECON data set to make sure that a corresponding DBD is also in a DBD library. Required JCL statements include:
|
INDD=
The INDD= operand can be used to override the default value of the input DD statement.
Required or Optional | Optional |
Synonyms | None |
Values | Any valid DDname which identifies an appropriate input library or data set. |
Default Value | The default input DDname is dependent on the TYPE= operand value. The TYPE= value table identifies the default DDname unless overriden by the INDD= operand. |
TYPE= value
TYPE= value | Default INDD= value |
|---|---|
ACB | ACBLIB |
DBD | DBDLIB |
PSB | PSBLIB |
RECON | RECON1 |
ACBINDD=
Whenever an ACB library is needed, you must provide a DD JCL statement which points at the library. The default DDname is assumed to be ACBLIB. However, you may override the default by specifying the DDname in the ACBINDD= operand.
Required or Optional | Optional |
|---|---|
Synonyms | None |
Values | Any valid DDname which identifies an appropriate input library or data set. |
Default value | ACBLIB |
DBDINDD=
Whenever a DBD library is needed, you must provide a DD JCL statement which points at the library. The default DDname is assumed to be DBDLIB. However, you may override the default by specifying the DDname in the DBDINDD= operand.
Required or Optional | Optional |
|---|---|
Synonyms | None |
Values | Any valid DDname which identifies an appropriate input library or data set. |
Default value | DBDLIB |
REPORTS=
Use the REPORTS= operand to control the generation of several optional reports. Each REPORTS= suboperand refers to a specific report.
Required or Optional | Optional |
|---|---|
Synonyms | None |
Values | The valid values for each suboperand are YES or NO. The default suboperand value is YES. When you specify ALL=, it refers to sub operands that apply to the value you specified for the TYPE= operand. For example, when you specify TYPE=PSB, REPORTS=ALL refers to the XREFDBD and XREFPCB suboperands. The Applicable REPORTS= Suboperand values table indicates which suboperands are applicable depending upon the TYPE= operand value. |
Default value | None |
Applicable REPORTS= Suboperand values
Applicable Suboperand | When TYPE= | |||
|---|---|---|---|---|
ACB | DBD | PSB | RECON | |
XREFDBD | x | x | x | |
XREFPCB | x | |||
XREFDMB | x | |||
XREFPSB | x | |||
ACBSIZE | x | |||
GENHIST | x | |||
GENDATCK | x | |||
ALL | x | x | x | x |
MBR=
The MBR= operand specifies the name of the library members to be cross checked.
The MBR= and MBRLIST= operands are mutually exclusive. If neither the MBR= nor the MBRLIST= operands is specified, then all the members in the input library are selected.
If you specify TYPE=ACB, the MBR= operand is ignored.
Required or Optional | Optional |
|---|---|
Synonyms | None |
Values | mbrname. You can specify a wildcard name. |
Default value | None |
PSBINDD=
Whenever a PSB library is needed, you must provide a DD JCL statement which points at the library.
Required or Optional | Optional |
|---|---|
Synonyms | None |
Values | Any valid DDname which identifies an appropriate input library or data set. |
Default value | PSBLIB You can override the default by specifying the DDname in the PSBINDD= operand. |
MBRLIST=
The MBRLIST= operand specifies a list of DBD library member names to be cross checked. The list may contain up to 10 names. The list must be enclosed in a set of parentheses and the names must be separated with a comma.
The product processes the members by type, in alphabetical order. For example, a MBRLIST with ACBLIB will process the DMBs in alphabetical order followed by the PSBs in alphabetical order.
The MBR= and MBRLIST= operands are mutually exclusive. If neither the MBR= nor the MBRLIST= operands is specified, then all the members in the input library are selected.
If you specify TYPE=ACB, the MBRLIST= operand is ignored.
Required or Optional | Optional |
|---|---|
Synonyms | None |
Values | One to ten member names separated by commas. Wildcard names are not allowed. |
Default value | None. You must specify at least one name. |
