How to Use

Populate tablespace_control:

• Use the output from parse_tablespace_script.sql (artifact ID a903bb09-da7e-470a-a396-623c177a7737) to insert your 64 tablespaces:
  sql

  INSERT INTO tablespace_control (tablespace_name, initial_size_gb) VALUES ('TABLESPACE1', 6268);

  INSERT INTO tablespace_control (tablespace_name, initial_size_gb) VALUES ('TABLESPACE2', 3000);

  -- Add all 64

  COMMIT;
• Verify:
  sql

  SELECT COUNT(*) FROM tablespace_control;

2. Run the Script:
   • In TOAD SQL Editor, execute the script with SET SERVEROUTPUT ON;.
   • Output shows progress (e.g., Created: TABLESPACE1, Skipped: TABLESPACE2 (already exists), Failed: TABLESPACE3 - ORA-01658).
   • The script skips existing tablespaces (SKIP_EXISTS), retries failures (3 times), and logs to tablespace_log.
3. Mitigate TOAD Timeout:
   • Batch size is reduced to 5 (v_batch_size = 5) with 120-second pauses (DBMS_LOCK.SLEEP(120)) to minimize session timeout risk.
   • In TOAD, increase session timeout if possible (check “Database” > “Session” settings).
   • If timeout occurs, re-run the script—it resumes from PENDING or FAILED tablespaces.
4. Monitor:
   • Check logs:
     sql

     SELECT log_id, tablespace_name, action, status, error_message, log_time

     FROM tablespace_log

     WHERE action IN ('CREATE', 'SKIP_EXISTS', 'AUTO_RETRY')

     ORDER BY log_time DESC;
   • Check status:
     sql

     SELECT tablespace_name, initial_size_gb, status, retry_count, last_attempt

     FROM tablespace_control

     ORDER BY tablespace_name;
   • Verify tablespaces:
     sql

     SELECT tablespace_name, bigfile, ROUND(bytes/1024/1024/1024, 2) AS size_gb

     FROM dba_tablespaces

     WHERE tablespace_name LIKE 'TABLESPACE%'

     ORDER BY tablespace_name;
5. Retry Failures:
• Reset failed tablespaces:
  sql

  UPDATE tablespace_control SET status = 'PENDING', retry_count = 0 WHERE status = 'FAILED';

  COMMIT;
• Re-run the script.

How to Use in Your Workflow

1. Backup tablespace_control (Optional):
   • Before deleting, save the current rows to restore later:
     sql

     CREATE TABLE tablespace_control_backup AS SELECT * FROM tablespace_control;
   • Or save INSERT statements:
     sql

     SELECT 'INSERT INTO tablespace_control (tablespace_name, initial_size_gb) VALUES (''' || tablespace_name || ''', ' || initial_size_gb || ');'

     FROM tablespace_control;
2. Run the DELETE:
   • Modify the DELETE statement with your desired tablespaces (e.g., first 10):
     sql

     DELETE FROM tablespace_control WHERE tablespace_name NOT IN ('TABLESPACE1', 'TABLESPACE2', 'TABLESPACE3', ..., 'TABLESPACE10');

     COMMIT;
   • Verify:
     sql

     SELECT tablespace_name, initial_size_gb, status FROM tablespace_control;
3. Run the Direct Execution Script:
   • Execute create_multiple_tablespaces_direct.sql (version dc078ecc-90db-4e89-9e90-306d80616933) in TOAD with SET SERVEROUTPUT ON;.
   • The script processes only the remaining tablespaces, skipping existing ones and logging SKIP_EXISTS.
4. Monitor:
   • Check logs:
     sql

     SELECT log_id, tablespace_name, action, status, error_message, log_time

     FROM tablespace_log

     WHERE action IN ('CREATE', 'SKIP_EXISTS', 'AUTO_RETRY')

     ORDER BY log_time DESC;
   • Check status:
     sql

     SELECT tablespace_name, initial_size_gb, status, retry_count

     FROM tablespace_control;
5. Add More Tablespaces:
   • Repopulate tablespace_control for the next batch:
     sql

     INSERT INTO tablespace_control (tablespace_name, initial_size_gb) VALUES ('TABLESPACE11', 2000);

     -- Add next batch

     COMMIT;
   • Re-run the script.

RDS-Specific Notes

• Timeout Risk: The direct script runs synchronously, so TOAD’s 1-hour timeout may interrupt large batches (e.g., 6268G tablespaces). The DELETE reduces this risk by limiting to 10 tablespaces. Adjust v_batch_size = 3and DBMS_LOCK.SLEEP(180) if needed.
• Storage: 10 tablespaces at ~3000G (~30 TB) is still significant. Check:
  sql

  SELECT SUM(bytes)/1024/1024/1024 AS total_gb FROM dba_data_files;
  Scale storage via AWS console if needed (max 64 TiB).
• Privileges: Ensure:
  sql

  GRANT CREATE TABLESPACE, CREATE TABLE TO your_username;

My Opinion

• Why DELETE Helps: Limiting to 10 tablespaces via DELETE is a practical way to manage TOAD timeouts while job_queue_processes = 0 awaits AWS Support resolution. It allows incremental progress without losing the skip-existing (SKIP_EXISTS) or retry functionality.
• Long-Term: Contact AWS Support to set job_queue_processes > 0 (e.g., 100) for true background execution using the original Scheduler script.
• Testing: Start with a small batch (e.g., 3 tablespaces at 1G) to confirm the script works:
  sql

  TRUNCATE TABLE tablespace_control;

  INSERT INTO tablespace_control (tablespace_name, initial_size_gb) VALUES ('TEST_TS_01', 1);

  INSERT INTO tablespace_control (tablespace_name, initial_size_gb) VALUES ('TEST_TS_02', 1);

  INSERT INTO tablespace_control (tablespace_name, initial_size_gb) VALUES ('TEST_TS_03', 1);

  COMMIT;

If you provide your 64 tablespace names/sizes, I can generate the exact INSERT and DELETE statements for your batches!
