Restrictions when using image copy data sets as input
The following restrictions apply when the input to the HD Pointer Checker is an image copy data set.
- HD Pointer Checker accepts the following types of image
copy as input database data set:
- A batch image copy
- A compressed batch image copy taken with IMS HP Image Copy
- An SMSNOCIC type image copy and an SMSOFFLC type image copy (Exceptions: SMSNOCIC type image copy of an encrypted database data set and extended format data set in compressed format are not supported.)
- A Fast Recovery image copy taken with IMS HP Image Copy 4.1 or later
- HD Pointer Checker can
process the following image copies. However, if the database is updated
while image copy is being taken, HD Pointer Checker might detect
pointer errors even if there are actually no pointer errors.
- An online image copy
- A concurrent image copy taken by a batch image copy or IMS HP Image Copy
- An SMSCIC type image copy and an SMSONLC type image copy (Exceptions: SMSCIC type image copy of an encrypted database data set and extended format data set in compressed format are not supported.)
- HD Pointer Checker does not support Database Image Copy
2 (IC2) image copy data sets that have the following characteristics:
- Contain multiple image copies
- Contain data that is compressed with the ZCOMPRESS option of the DFSMSdss DUMP command
- If the input to the HD Pointer Checker is a batch image copy data set created from an OSAM LDS data set, HD Pointer Checker assumes that the OSAM LDS data set has the extended addressability attribute defined and determines the size limit for the database data set.
