DataDirect IDMS Extensions OCA-DB2
DataDirect's IDMS Extension OCA-DB2 enables CA-IDMS programs to directly access IBM DB2 databases using standard SQL requests. Two-phase commit is available if used together with OCA-COMMIT. Access to DB2 is performed using the Call Attachment Facility (CAF) or the Recoverable Resource Manager Services Attachment Facility (RRSAF), if OCA-COMMIT is installed in the system.
Key Features
- Supports standard SQL requests
- Two-phase commit available with OCA-COMMIT
- Fully compatible with other OCA components
- Easily installed in two hours, less if you already use other OCA components
Using both OCA-DB2 and OCA-COMMIT enables you to perform simultaneous updates in both CA-IDMS and DB2 with 100% integrity between both databases.
Tedious work and maintenance costs eliminated
The traditional way of accessing DB2 from CA-IDMS is to use APPC to trigger a CICS program that performs the DB2 access and returns the requested information. APPC programming can be tedious and maintaining those programs can be expensive. OCA-DB2 makes it very easy to access DB2 data, and you get two-phase commit capabilities.
CV performance maintained
Accessing DB2 databases is as simple as coding the SQL requests in your COBOL program, running the program through the DB2 pre-compiler and then through your usual CA-IDMS procedure. You can use both dynamic and static SQL. When you execute the program within CA-IDMS, OCA-DB2 will allocate a DB2 connection and perform the requests without any impact on the CV performance.
