To extract DB2 schema objects

From the HCOSS Extract Schema tool, click the Schema Extract tab.

Do one of the following:

If using a direct connection to z/OS DB2:
1. In the Connection group, select DB2 DSN.
2. From the Connection drop-down list, select the DB2 connection you created using the Manage Connections tool that points to the DB2 database containing the schema objects that you want to extract.
If using the offline schema extract solution:
1. In the Connection group, select SQL Server DSN.
2. From the Connection drop-down list, select the SQL Server connection you created using the Manage Connections tool that points to the SQL Server database containing the schema objects that you want to extract.
  Note: For detailed information about using the offline extract schema solution, see Offline Extract Schema Solution.

If prompted, provide your user ID and password.

Click New.

In the Schema Extract Name field, type a name for the generated schema extract file.

In the Metadata/Catalog Schema Name field, type the name of a schema containing alternative views of the SYSIBM table. Optional.

Note: This feature enables users to access the information in SYSIBM tables without having access to the SYSIBM catalog. In this case, you must create the alternative schema before running the Extract Schema tool.

Click OK.

On the Schema Extract tab, choose one of the following:

Local	To save the generated schema extract file to the directory specified by the Local HCOSS Directory HCOSS option.
Shared	To save the generated schema extract file to the directory specified by the Shared HCOSS Directory HCOSS option.

On the Select schema(s) to extract list, check the box that corresponds to each schema you want to extract.

In the Table Row Count group, select one of the following:

Estimated using schema statistics - to record the estimated table row count based on the schema statistics stored in SYSIBM.SYSTABLES. Use this option to improve performance.
Both Estimated using schema statistics and Actual using SELECT BIG_COUNT(*) - to record both the estimated table row count and the actual row count as retrieved using a SELECT BIG-COUNT(*) query. Use this option to provide accuracy.
Note: This option is not available when using the offline extract schema solution.

Click Extract.

On the Results tab, verify that the schema extract file has been generated properly.

Note: If you get a -551 SQL error extracting a table, no schema is extracted. To correct this, have your DB2 DBA grant you READ access to the table that generated the error; then rerun the Extract Schema tool.

On the Schema Extract tab, click Save to save the settings.
