NOTE: I have created MLOGS for the base tables GL.GL_JE_BATCHES, GL.GL_JE_HEADERS, GL.GL_JE_LINES, GL.GL_JE_CATEGORIES_TL, GL.GL_JE_SOURCES_TL, GL.GL_CODE_COMBINATIONS, APPLSYS.FND_LOOKUP_VALUES, APPLSYS.FND_ID_FLEX_STRUCTURES, APPLSYS.FND_ID_FLEX_SEGMENTS, APPLSYS.FND_FLEX_VALUES,APPLSYS.FND_FLEX_VALUES_TL.

We have created synonyms from the above base tables to APPS schema. APPS.gl_je_batches, APPS.gl_je_headers, APPS.gl_je_lines, APPS.GL_JE_CATEGORIES_TL, APPS.GL_JE_SOURCES_TL, APPS.gl_code_combinations, APPS.FND_LOOKUP_VALUES, APPS.fnd_id_flex_structures, APPS.fnd_id_flex_segments, APPS.fnd_flex_values, APPS.fnd_flex_values_tl, APPS.fnd_id_flex_structures, APPS.fnd_id_flex_segments, APPS.fnd_flex_values, APPS.fnd_flex_values_tl, APPS.fnd_id_flex_structures, APPS.fnd_id_flex_segments, APPS.fnd_flex_values, APPS.fnd_flex_values_tl.

But I'm getting the below error

AND flv.VIEW_APPLICATION_ID = 101 * ERROR at line 76: ORA-12052: cannot fast refresh materialized view APPS.XXARG_ACC_ANALYSIS

Or if I try to do Complete refresh, it displays me the below error

AND flv.VIEW_APPLICATION_ID = 101 * ERROR at line 76: ORA-01114: IO error writing block to file 201 (block # 4154889) ORA-29701: unable to connect to Cluster Manager ORA-01114: IO error writing block to file 201 (block # 4154889) ORA-29701: unable to connect to Cluster Manager

Please help me on this.

Ok, so 2 problems here:

  1. ORA-29701 this may be caused by a bug, permission issue with the executables or other environmental errors, such as deleting socket files from the tmp directory. First investigate this.

  2. ORA-12052: cannot fast refresh materialized view. For this:

Diagnosing ORA-12004 Refresh Fast Cannot be Used (Doc ID 179469.1)

1.8 Materialized View References Synonyms or Views

Fast refreshable materialized views can be created based on master tables and master materialized views only. Materialized views based on a synonym or a view must be complete refreshed. This actually is a consequence of the cause discussed in Section 1.3. From 8.1.6 onwards, use of a synonym or a view in place of a direct reference to a master table renders the materialized view complex, and thus it cannot be fast refreshed. This can be seen if a direct attempt is made to create the materialized view as fast refreshable when it references synonyms or views.

But instead of manually searching for reasons why fast refresh is not possible, let the database do the work:

Run $ORACLE_HOME/rdbms/admin/utlxmv.sql to create the MV_CAPABILITIES_TABLE.

Use DBMS_MVIEW.EXPLAIN_MVIEW to explain the mview:

begin
  DBMS_MVIEW.EXPLAIN_MVIEW ('create materialized view ....');
end;
/

After that you can find the reason why fast refresh is not possible in MV_CAPABILITIES_TABLE.
