• trying to alter or add POs in PS0A

Solution

The underlying error  'ORA-01653: unable to extend table TABLE_NAME by XXX in tablespace TABLESPACE_NAME' happens because a background process is trying to create a record in the database but it has found a lack of available disk space to add data in one of its data files.

In order to get rid of this error, the simplest solution is to resize the data file associated with the failed tablespace, giving it available space to resume inserting data. 

1. Connect to the database as a DBA.
2. Identify which data file or files are associated with the failed tablespace. It might have expanded into multiple data files. To identify the data files, use the following SQL statement:
   

   select a.owner, b.file_name 
   from dba_tables a, dba_data_files b 
   where a.tablespace_name=b.tablespace_name and a.table_name='Your table name'

3. Resize the data file using the following SQL statement, providing its new size in Megabytes (M) or Gigabytes (G).

   alter database datafile '/eva_cims2/oradata/B/dbsB.igtd3' 
   resize 21500M

4. In case the Disk volume has no further space to grow and a new data file needs to be created in a different volume, use a SQL similar to this:

   ALTER TABLESPACE tablespace_name ADD DATAFILE '/eva_cims2/oradata/B/dbsB.sp6' 
   SIZE 3000M;

   Note: The queries will need to be adjusted according to the client's implementation and architecture.
