This is represented in the picture by the box in the middle of the chart. 1). COPY PLUS starts a concurrent copy. The table space it is copying has been registered to XBM. 2). DB2 is still performing reads and writes to the table space. Page 200 is read into DB2. When DB2 performs the write back to DASD, 3). XBM “sees” the write, and before the write completes, XBM brings the pre-updated image of the page into XBM’s cache. 4).

When a write is staged from the DB2 Buffers, XBM intercepts and detains the write. If COPY PLUS has already copied the affected page, the write is allowed through. If COPY PLUS has NOT copied the page, XBM retrieves the unchanged page from DASD and holds it in the DATASPACE. The write for that page is then allowed through. When COPY PLUS is ready to copy the affected page, it is retrieved from the XBM DATASPACE.

Current Application Recovery Mainframe Solution Sets Coordinated Recovery Manager Recovery Manager for DB2 SAP Recovery Manager for IMS Recovery Manager for OS/390 COPY PLUS for DB2 IMAGE COPY PLUS RECOVERY UTILITY for VSAM DFSMS or ABARS RECOVER PLUS for DB2 RECOVERY PLUS for IMS BMC automates the process of backing up and recovering all components of the application. Our solutions minimize application and business process “down time” and reduce or eliminate data loss. For relational databases, our Log Master product also provides the ability to perform an “online recovery” in the event of an administrative or application logic error. For example, if a DBA accidentally deletes 50 rows out of a table instead of 5, Log Master can find that erroneous change, and generate SQL to UNDO the change -- allowing the DBA to recover the data without taking the database, the application, or the business process off line.
