Resolution

To start up ACF2 using the alternate databases(ALT) on an IPL you can add the DDSN(ALT) when starting ACF2. There are different methods which depend on how your site starts ACF2.

If you use SYS1.PARMLIB CAISEC00 and CAIACFxx members to start ACF2 you can add DDSN(ALT) in your CAIACFxx member.

For example:

EDIT       SYS1.PARMLIB(CAISEC00) - 01.20                  Columns 00001 00072
Command ===>                                                  Scroll ===> CSR 
****** ***************************** Top of Data ******************************
000001 ACF2(01 START)
****** **************************** Bottom of Data ****************************

EDIT       SYS1.PARMLIB(CAIACF01) - 01.08                  Columns 00001 00072
Command ===>                                                  Scroll ===> CSR 
****** ***************************** Top of Data ******************************
000001 SYSID(TESTCPU)
000002 BACKUP 
000003 DDSN(ALT) 
****** **************************** Bottom of Data ****************************

If you use SYS1.PARMLIB COMMNDxx member to start ACF2, you can add DDSN(ALT) to the S ACF2 command PARM.

For example: 

S ACF2,PARM='BACKUP,DDSN(ALT)'
