Issue/Introduction

Question:

Can the LXX be allocated with Secondary Extents like: (CYL,(1500,100))?

Answer:

- Short answer: LXX cannot be EXTENDed into secondary extents but can be INITed on multi volumes/extents.

- Long answer: Extracted from CA Datacom/DB DBUTLTY Reference Guide:

Multivolume INITs

The Log Area can exist as one or more extents on one or more volumes depending on operating system requirements and operating system maximums. If initializing an existing data set (DISP=SHR or DISP=OLD), CA Datacom/DB formats all currently allocated tracks for use. If initializing a new data set (DISP=NEW), CA Datacom/DB requests and formats the primary allocation only if one volume is provided. If multiple volumes are provided, CA Datacom/DB requests secondary allocations until space has been allocated on the number of volumes specified. For a description of how the operating system handles secondary allocations, see your operating system JCL manual.

 So, (CYL,(1500)) or (CYL,(1500)),VOL=VOL1,VOL2 will work too...
