Control File Maintenance Utility › Control File Statements › DELETE Statement

DELETE Statement

The DELETE statement is used to remove the following from the Control File:

• A VSAM data set or pattern definition
• A physical sequential data set or pattern definition
• A system entry

  DELETE 	{DSNAME=data setname|PATTERN=patternname|PSDSNAME=data setname|
  	 PSPATTERN=patternname|SYSTEM=systemname}
  	[,ONLY]
  

DSNAME=data-setname

Specifies the name of a VSAM entry to DELETE from the Control File. The value should be a valid cluster or path name, not a data component name or physical sequential data set name. If it is a cluster name and ONLY is not specified, the cluster entry and all its associations are deleted from the Control File. If it is a path entry, only the path entry is deleted.

PATTERN=patternname

Specifies the name of a VSAM pattern entry to DELETE. The entry can contain any character valid in a data set name, together with special characters ?, *, ! and/or /. These special characters are defined in the section Syntax Rules in this chapter.

PSDSNAME=data-setname

Specifies the name of a physical sequential data set to DELETE from the Control File.

PSPATTERN=patternname

Specifies the name of a physical sequential pattern to DELETE. The entry can contain any character valid in a data set name, together with special characters ?, *, ! and /. These special characters are defined in the section Syntax Rules in this chapter.

SYSTEM=systemname

Specifies the system name of a currently inactive CA Compress system that is to be deleted from the Control File. The SMF system id is used to maintain the in-storage list of patterns whenever they change. You do not need to DELETE the system name regularly because it is automatically removed when the CA Compress subsystem is brought down normally.

If a system name on the Control File is identical to the one currently starting and it has not been used for more than 2 minutes, it is reused automatically. You are queried at startup if the system entry has been used in the last 2 minutes to determine if it should be reused. You are informed that it is not possible to start CA Compress if 8 system names are in the Control File and you must add one. Then you must delete (using the DELETE statement) one of the inactive entries.

ONLY

Specifies that only the record specified in the DSNAME parameter is to be removed from the Control File, even when DSNAME is a cluster. ONLY is intended to remove orphan records in the Control File resulting from hardware or system failures.
