The first method only affects one database unit, the second method affects all database units in which the component owning the file is installed.
To delete a file from the weekly history archive tape of a particular unit, without affecting other units, follow these steps:
- Edit prefix.MICS.PARMS(DBMODEL).On the FILE statement for the file you want to delete, specify a cutoff limit of zero in the weekly history archive position.For more information about the FILE statement in DBMODEL, see Data Retention Specifications (FILE Statement).
- Submit the prefix.MICS.CNTL(CYCLEGEN) job.This job changes the component's executable code in the prefix.MICS.USER.SOURCE library and affects only the database unit in which the component is installed.
- Edit prefix.MICS.PARMS(JCLGENU). Specify:WEEKLY HISTW
- Submit the prefix.MICS.CNTL(JCLGENU) job.
This generates the WEEKLY or HISTW job JCL or both This JCL contains DD statements for the new weekly history configuration.
To delete a file from the weekly history archive tape, affecting all database units in which the component is installed, follow these steps:
- Edit the FILE statement in sharedprefix.MICS.GENLIB(cccGENIN). Change the "Y" in the file's weekly history archive position to "N".For more information about the GENIN FILES statement, see Retrofitting Database Files.
- Submit the sharedprefix.MICS.CNTL(cccCGEN) job to regenerate the component.
- Submit the prefix.MICS.CNTL(CYCLEGEN) job for all database units in which the component is installed.This job changes the component's executable code in the prefix.MICS.USER.SOURCE libraries and affects only the database units in which the component is installed.
- Edit prefix.MICS.PARMS(JCLGENU) for all database units in which the component is installed. Specify:WEEKLY HISTW
- Submit the prefix.MICS.CNTL(JCLGENU) job(s).This generates the WEEKLY or HISTW job JCL, or both This JCL contains DD statements for the new weekly history configuration.For example, assume that the NPANCP file example showed the file appearing in the following archives:WEEKLY WEEKLY MONTHLY AUDIT HISTORY HISTORY -------- -------- -------- NO YES YESAssume the desired configuration is:WEEKLY WEEKLY MONTHLY AUDIT HISTORY HISTORY -------- -------- -------- NO NO YESThe initial definition of the NPANCP file statement in sharedprefix.MICS.GENLIB(NPAGENIN) would have been:FILE NCP 00 1 Y Y Y Y N N Y Y NCP Activity File | | | no WEEKLY audit -----+ | | WEEKLY history -------+ | MONTHLY history ---------+Change this statement to:FILE NCP 00 1 Y Y Y Y N N N Y NCP Activity File | +- no WEEKLY history produced
