SQLUTBxx LOAD

Note: これは技術評価機能としてのみ提供されます。この新機能について、テストおよびフィードバックができるようになる予定です。ただし、この機能はプロダクション使用を目的としたものではなく、プロダクション使用はサポートされていません。また、この機能は GA レベルでの提供が保証されるものではないため、実際提供されるバージョンは技術評価版と大きく異なる可能性があります。

The SQLUTB232 and SQLUTB264 utilities are designed to work with LOAD cards generated by DSNUTILB UNLOAD on the mainframe as well as those generated by an SQLUTBxx UNLOAD utility. 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: SQLUTBxx LOAD requires that you modify the LOAD control statement created on the mainframe to include either the REPLACE YES or the RESUME YES option. If neither is included, the JCL job terminates with an abend.

Executing SQLUTBxx LOAD

To use SQLUTBxx LOAD, either create a JCL application project or directly submit JCL using the JES CONTROL feature in Enterprise Server. The JCL syntax must be DB2 compatible.

The following is an example of JCL using a LOAD card generated on the mainframe:

//DSNCUSTM JOB
//DSNUPROC 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 connection to a SQL Server database, SQLUTB32 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 YES: REPLACE YES is mutually exclusive to RESUME YES. Either REPLACE YES or RESUME YES is required.
If neither REPLACE YES 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 utility 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 not effective; however the syntax is recognized.
RESUME YES: RESUME YES is mutually exclusive to REPLACE YES. Either RESUME YES or REPLACE YES is required.
If neither RESUME YES nor REPLACE YES are present, warnings are generated based on the target table having an empty status.
