SQLUTB LOAD

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 YES|NO
YES
Default value.
NO
Supported if the user has the privileges of ALTER TABLE ACTIVATE NOT LOGGED INITIALLY WITH EMPTY TABLE.
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.
