    1- Apply fails with incorrect message when col_type in
    asn.ibmsnap_subs_cols contains invalid value
    2- applytrail contains no error information when Apply failed
    to connect to target
    3- MAXCMTSEQ was not saved thus Capture read the STOP signal
    again upon restart
    4- Transmgr destructor attempts to delete global subtrans from
    the minLSN chain
    5- 92 million rows caused negative index in to the keyblock
    array
    6- Remove the invalid check in the restart message for warm
    start
    

Problem conclusion

  • 1- issue message ASN1036 when col_type is invalid
    2- issue message ASN1003 in applytrail if Apply can not connect
    to target server
    3- Capture now saves the restart info when stopping
    4- global subtrans will be deleted when global anchor trans are
    deleted.
    5- fixed the negative indexing by not using the macro
    6- Check is now removed
    

Temporary fix
