Hello All,

I wrote a rexx code and invoked it through IKJEFT01. since i am using ISPEXEC services i made the following allocations in the jcl.

Code:
//ISPPROF  DD UNIT=SYSDA,SPACE=(6160,(7,7,5),RLSE),   
//                  DCB=(RECFM=FB,LRECL=80,BLKSIZE=6160)   
//ISPPLIB  DD  DSN=SYS2.ISPF.PLIB,DISP=SHR           
//ISPSLIB  DD  DSN=SYS2.ISPF.SLIB,DISP=SHR           
//ISPTLIB  DD  DSN=SYS2.ISPF.TLIB,DISP=SHR           
//ISPMLIB  DD  DSN=SYS2.ISPF.MLIB,DISP=SHR           
//ISPLOG   DD UNIT=SYSDA,SPACE=(6160,(7,7,5),RLSE),   
//              DCB=(RECFM=FB,LRECL=80,BLKSIZE=6160)

As seen above for ISPPROF and ISPLOG i have used temporary dataset allocation so as to avoid any conflict during batch execution.

ISPPROF dataset gets allocated and freed without any problems. but for ISPLOG the following informational message is displayed.

Code:
 SYS12055.T051628.RA000.PCIREXA.R0493534 was preallocated (no free was done). 


The program runs fine without any problems . But should i be concerned with the message dsplayed. If so how to avoid it.

Could any one please help me on this?

I do not think I have ever allocated ISPLOG. And I guess the reason I do not need to is because IKJEFT01 allocates it as the message seems to indicate. If you look up the error message number you will probably find out.
