With the help of CHKOBJ clp command, we can find existence of object on the system.
The usage of command in clp is as follows:
CHKOBJ OBJ(JBA001DT) OBJTYPE(*DTAARA)
MONMSG MSGID(CPF9801) EXEC(DO)
CRTDTAARA DTAARA(QGPL/JBA001DT) TYPE(*CHAR) LEN(6) +
VALUE('010196') TEXT('The last day that had job acct.+ data extracted')
ENDDO
RTVDTAARA DTAARA(JBA001DT *ALL) RTNVAR (&FROMDATE)

The execution of above steps is listed below:

steps

1: First it checks the data area object on the system.

2: If the data area object not found, the MONMSG command executes with the help of message identifier, next we can dynamically create the data area.
3. If the data area object found, control transfers to statement below ENDDO.

It is always good CLP programming approach to check the object before you rename, delete the objects on the system.
