Sample Schema Verification Report and Abend Messages

Sample Schema Verification Report and Abend Messages

The sample schema verification report shows the messages and information that are displayed when schema verification fails.
In this example, schema verification fails because the schema in the capture registration contains a column that is not defined in the DB2 catalog. This situation can occur if a column was removed from the table after the table was registered.
The following example report shows the output and abend messages that are printed:
PWXEDM177502I Table 'ABCOOK1.PLOB2A' the DB2 schema does not match the active profile schema. DB2 log time = 2017-05-04-20.47.33.379616. ----------------------- DB2 Catalog ------------------------ | ------------------- PWX Registration ----------------------- Create timestamp = 2017-05-04-20.39.29.360081 | Alter timestamp = 2017-05-04-20.45.14.567313 | # NL Column Name Datatype Len Pr Sc N | # NL Column Name Datatype Len Pr Sc N --- -- ------------------------------ -------- ----- -- -- - | --- -- ------------------------------ -------- ----- -- -- - 1 3 KEY Integer 4 0 0 N | 1 3 KEY Integer 4 0 0 N 2 3 C01 CLOB 0 0 0 Y | 2 3 C01 CLOB 0 0 0 Y 3 28 DB2_GENERATED_ROWID_FOR_LOBS ROWID 17 0 0 N | 3 28 DB2_GENERATED_ROWID_FOR_LOBS ROWID 17 0 0 N 4 7 NEWCOL1 CLOB 0 0 0 Y | PWXEDM177511E Table 'ABCOOK1.PLOB2A' Schema verification failed.
