Question: 

 When executing the following Dynam Job to get a Catalog STATUS Report

// EXEC DYNCAT,SIZE=128K 
STATUS 

We receive the following Output:

TOTAL VOLUMES CATALOGUED 5501 
TOTAL ACTIVE VOLUMES 3113 
TOTAL ACTIVE VERSIONS 3221 
TOTAL SCRATCH VOLUMES 2388 
TOTAL NUMBER OF DATA SETS 911 
PERCENT OF FILE AVAILABLE 93% 
PERCENT OF INDEX AREA USED 400% 
PERCENT OF DATA AREA USED 13% 
HIGH WATER MARK PERCENT 13% 

Why do we see ? PERCENT OF INDEX AREA USED 400%

 

How can we change this ?

Answer:

Answer: 

during the installation of CA Dynam there was a step to FORMAT the Dynam catalog (CAICATL) by:
// EXEC DYNCAT,SIZE=128K 
INITIAL 

The INDEX AREA is calculated by the following keywords. 

DATAsets=nnnnnn 
Number of data sets (tape and disk) to be controlled 
Optional parameter. Specifies the number of datasets that the Catalog will 
contain. A valid entry is a 1- to 6-digit number. The default is 250. 


VOLumes=nnnnnn 
Number of tape volumes to be controlled 
Optional parameter. Specifies the number of volume serial numbers that the 
Catalog will contain. A valid entry is a 1- to 6-digit number. The default is 1000. 

In this case 5500 Volumes and 900 Dataset are controlled by Dynam. When it was not defined during the INITIAL the default is used and is exceeding the INDEX AREA

there is a worksheet available in the Installation Guide 
Worksheet for Estimating Catalog File Size 
Page 3-7 
which explains the calculation. 

for this case an example what to do to correct the % display: 
// EXEC DYNCAT,SIZE=128K 
RESTORE REORG DATAsets=1200 VOLUMES=6000 SHARE=YES
