How to Resize a zFS Linear Data Set

Web Services is installed as a linear VSAM file, iprfx.iqual.CSIQUSSM, which contains a file system that is mounted to a user-defined mount point on the Z/OS UNIX file system.

A user can receive the error message “EDC5133I No space left on device”, which indicates that there is no free space left in the z/OS UNIX file system. As a Web Services administrator, you can allocate additional space for the file system.

A sample batch JCL job, WSZFSRSZ, is delivered in iprfx.iqual.CSIQJCL. This job, in summary, does the following:

1. Deletes work files
2. Produces details of the original zFS linear data set into the job output
3. Unmounts the original zFS linear data set from the z/OS UNIX file system
4. Allocates a new zFS linear data set with your allocation values
5. Creates a backup data set with the data from the original zFS data set
6. Alters the name of the original zFS linear data set to ‘zFSFile.OLD’
7. Alters the name of the new zFS linear data set to the original zFS linear data set name
8. Restores the data from the backup data set into the resized zFS linear data set
9. Produces details of the resized zFS linear data set into the job output
10. Mounts the resized zFS linear data set to the z/OS UNIX file system

After the successful execution of the batch JCL job, WSZFSRSZ, you can view the job output or view the VSAM attributes to verify the data set was resized correctly.
