The IMSID option refresh and TSS refresh facilities are available from the Refresh Menu.
The IMSID Options refresh updates the ETA options in use in an IMS Control Region. The TSS refresh updates the TSS table data in use in an IMS system by purging all data from the TSS cache buffers. ETA reloads the data as your TSS tables are accessed. This process allows you to make changes to TSS tables immediately available for use. The TSS refresh is only effective if you use cache buffering for access to TSS table data and if you have specified that ETA use five or more TSS cache buffers.
