Issue/Introduction

The index (IXX) for one of our Disk Datacom databases is currently at nn% full. Once it reaches 100% will it dynamically extend? 

Resolution

The Disk database data sets have been defined to automatically extend while space remains. 
Run the DBUTLTY to get the information for the IXX and verify that dynamic extend was set to Y. 

1. Run DYNAMIC EXTEND = YES. and  DYN.EXT.TRACKS = 0. 
2. Execute DBUTLTY to verify that the IXX is defined to dynamically extend.

//SYSIN     DD *           
REPORT AREA=CXX,DBID=nnn

3. This should create a a report and find on "IXX'  to verify that DYNAMIC EXTEND is equal to YES.
4. It will use what was put in secondary allocation when it was initially allocated in the IXX.

For example: 

//IXX770   DD DISP=(NEW,CATLG),                      
//               DSN=hlq.LVLnnn.IXXXXX,             
//               VOL=SER=(vol1,vol2),
//               SPACE=(CYL,(3000,0150)),

in the above case it will take dynamic extent of 150 cyls.
