SQLUTB LOAD is designed to work with LOAD cards generated by DSNUTILB UNLOAD on the mainframe as well as LOAD cards generated
by SQLUTB UNLOAD itself. For example, the following UNLOAD control statements generate valid LOAD statements:
UNLOAD DATA FROM TABLE HCOSQL.CUSTOMER
UNLOAD TABLESPACE HCOSQL.HCOTS FROM TABLE HCOSQL.EMPLOYEE
Important:
- SQLUTB LOAD requires that you modify the LOAD control statement created on the mainframe to include either the REPLACE or
the RESUME YES option. If neither is included, the JCL job terminates with an abend.
- You can configure the SQLUTB LOAD date format to specify the format(s) of date values in the input dataset. See
mbdtconfig command for details.
Executing SQLUTB LOAD
To use SQLUTB LOAD,
either create a JCL application project or
directly submit JCL using the JES CONTROL feature in
Enterprise Server. The JCL syntax must be z/OS DB2 compatible.
The following is an example of JCL using a LOAD card generated on the mainframe:
//DSNCUSTM JOB
//DSNUTILB EXEC PGM=HCOUTILB,PARM='HCOD,SH '
//*
//SYSPRINT DD SYSOUT=*
//UTPRINT DD SYSOUT=*
//SYSUDUMP DD SYSOUT=*
//STPRIN01 DD SYSOUT=*
//IDIOFF DD DUMMY
//*
//SYSUT1 DD DISP=MOD,DSN=SH.DSNUTILB.SYSUT1
//SORTOUT DD DISP=MOD,DSN=SH.DSNUTILB.SYSOUT
//SYSMAP DD DISP=MOD,DSN=SH.DSNUTILB.SYSMAP
//SYSERR DD DISP=MOD,DSN=SH.DSNUTILB.SYSERR
//SYSREC DD DISP=SHR,DSN=SH.HCOSQL.CUSTOMRS
//SYSIN DD *

Where HCOD is the ODBC XAR ID for your database connection, SQLUTB has been established as an alias for program HCOUTILB,
and SH.HCOSQL.CUSTOMRS is the cataloged data file mapped to SYSREC.
LOAD Options
- Standard LOAD Options
-
- DATA
- Syntactically optional.
- REPLACE
- REPLACE is mutually exclusive to RESUME YES. Either REPLACE or RESUME YES is required.
If neither REPLACE nor RESUME YES are present, warnings are generated based on the target table having an empty status.
- DISCARDDN
- This option behaves differently from DB2 for z/OS in handling unique index. The tool does not check for duplicates in the
input data set, but instead forwards all data to the database. If duplicate records exist in the data set, only the first
instance is loaded into the target table, assuming that no existing record in the table has the same index.
- LOG NO|YES
- This option is syntactically accepted, but ignored, as LOG YES is the only supported behavior.
- RESUME YES
- RESUME YES is mutually exclusive to REPLACE. Either RESUME YES or REPLACE is required.
If neither RESUME YES nor REPLACE are present, warnings are generated based on the target table having an empty status.

Important: SQLUTB LOAD commit behavior can be configured to issue one commit or multiple commits. See
MBDT Configuration Utility for details.
Note: To ensure proper parsing of SYSIN, do not include the tab character (ASCII decimal character code 9; EBCDIC decimal character
code 5) in its contents. When parsed, the tab character could cause spurious, unintended errors.
