Unusable partition Oracle / datastage - oracle

Question

I am facing an issue with my datastage job. I have to fill a table ttperiodeas in Oracle from a .csv file. The SQL query in Oracle connector is shown in this screenshot:
Oracle connector
And here is the oracle script
CREATE TABLE TTPERIODEAS
(
CDPARTITION VARCHAR2(5 BYTE) NOT NULL ENABLE,
CDCOMPAGNIE NUMBER(4,0) NOT NULL ENABLE,
CDAPPLI NUMBER(4,0) NOT NULL ENABLE,
NUCONTRA CHAR(15 BYTE) NOT NULL ENABLE,
DTDEBAS NUMBER(8,0) NOT NULL ENABLE,
DTFINAS NUMBER(8,0) NOT NULL ENABLE,
TAUXAS NUMBER(8,5) NOT NULL ENABLE,
CONSTRAINT PK_TTPERIODEAS
PRIMARY KEY (CDPARTITION, CDCOMPAGNIE, CDAPPLI, NUCONTRA, DTDEBAS)
)
PARTITION BY LIST(CDPARTITION)
(PARTITION P_PERIODEAS_13Q VALUES ('13Q'));
When running the job, I get the following message error and the table is not filled.:
The index 'USINODSD0.SYS_C00249007' its partition is unusable
Please I need help thanks

Answer 1

The index is global (i.e. not partitioned) because there is no using index local at the end of the definition. This is also true for the PK index shown above. (I'm assuming they are two different things, because by default the DDL above would create an index named PK_TTPERIODEAS, so I'm not sure what SYS_C00249007 is.) If you can drop and rebuild them as local indexes (i.e. partitioned to match the table) then truncating or dropping a partition will no longer invalidate indexes.
For example, you could rebuild the primary key as:
alter table ttperiodeas
drop primary key;
alter table ttperiodeas
add constraint pk_ttperiodeas primary key (cdpartition,cdcompagnie,cdappli,nucontra,dtdebas)
using index local;
I don't know how SYS_C00249007 is defined, but you could use something similar.
The create table command might be something like:
create table ttperiodeas
( cdpartition varchar2(5 byte) not null
, cdcompagnie number(4,0) not null
, cdappli number(4,0) not null
, nucontra varchar2(15 byte) not null
, dtdebas number(8,0) not null
, dtfinas number(8,0) not null
, tauxas number(8,5) not null
, constraint pk_ttperiodeas
primary key (cdpartition,cdcompagnie,cdappli,nucontra,dtdebas)
using index local
)
partition by list(cdpartition)
( partition p_periodeas_13q values ('13Q') );
Alternatively, you could add the update global indexes clause when dropping the partition:
alter table demo_temp drop partition p_periodeas_14q update global indexes;
(By the way, NUCONTRA should probably be a standard VARCHAR2 and not CHAR, which is intended for cross-platform compatibility and ANSI completeness, and in practice just wastes space and creates bugs.)

Answer 2

the message says that the index for the given partition is unusable: so you could try to rebuild the correponding index partition by the use of
create index [index_name] rebuild partition [partition_name]
(with the fitting values for [index_name] and [partition_nme].
Before you do that you should check the status of the index partitions in user_indexes - since your error message looks not like Oracle error messages usually do.
But since the index is global as William Robertson pointed out, this is not applicable for the given situation.
