hi venkat
1 . u use DFSrrc00 program for IMS DB to run the we use IKJEFT01 for DB2 pgm and there are CALL 'CBLTDLI' statements which identifies the IMS programs
there is no program preparation process for IMSDB ( BIND,PLAN etc)
2. to browse IMSDB database we must use FILE-AID for IMS
3.All DL/I programs actually run as subroutines to the IMS. The IMS
program is named DFSRRC00 and the application program and PSB are
parameters coded on the execution statement.
// EXEC PGM=DFSRR00,
// PARM=(BMP,BMA001,BMAPSB,,,,,,1,,IMSS,,,N)
EXECUTION TYPE BMP
APPLICATION PROGRAM BMA001
PSB BMAPSB
TIMEOUT OPTION 1
CONTROL REGION ID IMSS
DBRC INDICATOR N
4. i suppose the parentage is lost then we try to insert new record .
5.it is not possible to update the key field of segment.
i hope these materails may help u
regards
