Index Maintenance

Index maintenance functions can be used to perform the following tasks:

• Add pre-existing SMF data sets to the SCDS without having to read the SMF data again
• Remove expired entries using DELETEX when the SCDS becomes full
• Update entries using UPDTX that have corrupted or incorrect data

You can review index entries for SMF history files using the LISTH control statement or the online interface.

Use the following control statements to manually manipulate the SCDS index:

• ADDX - Adds entries
• DELETEX - Deletes entries
• UPDTX - Updates entries

Business Value:

Manually manipulating the SCDS index lets you troubleshoot and resolve problems with the SCDS index without having to restore from a prior backup version and then reprocess SMF data.

Additional Considerations:

To add SMF data manually and bring it under the control of CA SMF Director, use the SOURCE control statement instead of ADDX. That will completely integrate pre-existing SMF data into CA SMF Director.

Use the FIRSTYEAR option on the DUMPOPTIONS control statement to set the oldest year of SMF data allowed in the SCDS file (starting with 1960).

Set this option to the oldest year of existing SMF data that you want to add to the SCDS. Setting this option as the current year minus the largest retention period for your SMF data provides the following benefits:

• Allows for back loading of existing SMF data into CA SMF Director
• Prevents error messages and the possibility of data not being added to the history files when incoming records predate the year specified on the FIRSTYEAR option.
