Disable all constraints in a library

When refreshing our development database with "live" production data, I always have to disable all the referential constraints before copying in the data. The following CL program makes that MUCH easier by changing the status on all constraints in the specified library to *DISABLED.

Before compiling the CLLE, create the data-file so that the compile will work. (Of course, substitute your library name for <mylib> .) 

 
DSPFD FILE(<mylib>/*ALL) TYPE(*CST)
     OUTPUT(*OUTFILE) FILEATR(*PF) 
     OUTFILE(Qtemp/ALLCST)

It's a VERY easy modification to create the program to enable all the constraints. 

  /***********************************************************/
/** Program: EnableIt                                     **/

/** Purpose: Disable all referential constraints and      **/
/**          check constraints on all physical tables in  **/
/**          the specified library                        **/
/***********************************************************/

DCLF FILE(Qtemp/ALLCST) ALWVARLEN(*YES)
DSPFD FILE(&DBLIB/*ALL) TYPE(*CST) + 
     OUTPUT(*OUTFILE) FILEATR(*PF) + 
     OUTFILE(Qtemp/ALLCST)
NEXT: RCVF

CHGVAR VAR(&CNAME) VALUE(%SST(&PHCSTN 3 256))
CHGPFCST FILE(&DBLIB/&CSFILE) CST(&CNAME) + 
STATE(*DISABLED)
GOTO NEXT
END:         ENDPGM
