Modifying IFI READS calls for the GDPS Continuous Availability with zero data loss environment
When you implement the GDPS Continuous Availability with zero data loss (GDPS Continuous Availability with zero data loss) solution, you need to modify your programs that issue IFI READS calls for IFCID 0306 to capture log records.
Before you begin
Before you can capture log records in a GDPS Continuous Availability with zero data loss (GDPS Continuous Availability with zero data loss) environment, you need to perform the tasks that are described in Modifying Db2 for the GDPS Continuous Availability with zero data loss solution.
Procedure
To modify an IFI READS call for IFCID 0306 to capture log records in a GDPS Continuous Availability with zero data loss environment:
Specify one of the following values in the WQALLCRI field in the IFI qualification area to
indicate that log records are being returned by the proxy data sharing group.
- X'01' (WQALLCR1)
- Only log records for changed data capture and unit of recovery control from the proxy data sharing group in a GDPS Continuous Availability with zero data loss environment. Records are returned until the end-of-scope log point is reached.
- X'02' (WQALLCR2)
- All types of log records from the proxy data sharing group in a GDPS Continuous Availability with zero data loss environment. Records are returned until the end-of-scope log point is reached.
- X'03' (WQALLCR3)
- Only log records for changed data capture and unit of recovery control from the proxy data sharing group in a GDPS Continuous Availability with zero data loss environment. Records are returned until the end-of-log point is reached for all members of the data sharing group.
- X'04' (WQALLCR4)
- All types of log records from the proxy data sharing group in a GDPS Continuous Availability with zero data loss environment. Records are returned until the end-of-log point is reached for all members of the data sharing group.
