Technical Info

Server Names

...

1.  For the Quarterly refresh only, update the latest RxNorm data for the medication subject area processing.
   1. Login using PuTTY terminal (or SSH GUI) to same server.
   2. Change directory to /dwhome/airflow_ci/master/dags/CDRN_ETL/RxNormLoad/
   3. Run file RxNormLoad.sh
2. Login to the appropriate Airflow server via a web browser
   1. Development: http://plt-nosql01.dhe.duke.edu:8083/admin/
   2. Production: http://plp-nosql01.dhe.duke.edu:8083/admin/
3. Edit the Airflow variable CDRN_ETL_Options_STAR
   1. Click Admin→Variables at the top of the Airflow web page.
   2. Click the Edit icon (pencil icon) for the entry CDRN_ETL_Options_STAR Image Modified
4. Make the following changes to these entries in the Airflow variable CDRN_ETL_Options_STAR

   1. runCabProcReload to false (true if full reload is needed)

   2. runEncounterReload to false (true if full reload is needed)

   3. runLabReload to false (true if full reload is needed)

   4. loadToDt to the previous day in YYYY-MM-DD format

   5. network to CVD19 for the mini-CDM refresh or STAR for the quarterly refresh

   6. prevPrefix to CVDNEW_ for the mini-CDM refresh or the previous V##_ prefix used for the last STAR refresh

   7. newPrefix to CVDNEW_ for the mini-CDM refresh or the next number available for V##_ prefix for the the current STAR refresh

   8. tempPrefix to ETL_

5. Start DAG process
   1. Click DAGs at the top of the Airflow web page.
   2. Scroll down the DAG list to the entry for STAR_ETL_Master.
   3. On the right side of the line, there are several icons. Click the Play button (Trigger DAG).
   4. Click OK on the confirmation popup window. This will start the DAG process.
6. Monitor DAG process
   1. Click on the link for the DAG STAR_ETL_Master from the main Airflow dashboard. This will open the DAG details page.
   2. Click either Graph View or Tree View to see the progress status of the DAG.
      1. Graph View - Will display a graph representation of all task being run and status of each task (Running, Finished, Failed, etc.) Does not display Task Duration Time correctly when hovering over the task. 
      2. Tree View - Will display a tree representation of specific amount of executions, including current execution. Task Duration Time does display correctly here when hovering over the task.
   3. Usual run time for entire process is 16-24 hours.
7. For quarterly refresh only, generate STAR hash token data.
   1. Login using PuTTY terminal (or SSH GUI) to same server.
   2. Change directory to /dwhome/airflow_ci/master/dags/CDRN_ETL/Datavant/
   3. Run file hash_token_load_master.sh STAR
8. For quarterly refresh only, execute post-ETL process
   
   1. Click DAGs at the top of the Airflow web page.
   2. Scroll down the DAG list to the entry for STAR_ETL_PostOp
   3. Run following SQL to backfill any missing hash tokens from previous step:
      

      1. INSERT INTO HSC_PCOR.<<V##>>_HASH_TOKEN 
         SELECT PATID, 'XXX - S00000', 'XXX - S00000', 'XXX - S00000', 'XXX - S00000', 'XXX - S00000', 'XXX - S00000', 'Backfill'
         FROM HSC_PCOR.<<V##>>_DEMOGRAPHIC WHERE PATID IN 
         (
         SELECT PATID FROM HSC_PCOR.<<V##>>_DEMOGRAPHIC vd 
         minus
         SELECT PATID FROM HSC_PCOR.<<V##>>_HASH_TOKEN
         );

   4. Once DAG finishes, login using PuTTY terminal (or SSH GUI) to same server.
   5. Change directory to /dwhome/apps/cdrnLoad
   6. Run following command to generate optimization stats for PCORNet tables

      1. nohup sqlplus 'HSC_PCOR/<<PASSWORD>>'@eclrprd1 @gatherStats_HSC_PCOR.sql &

9. For mini-CDM only, generate and send N3C data
   
   1. Login to the Windows server vwp-pmndmc.dhe.duke.edu via Remote Desktop Protocol (RDP).
   2. Open Windows File Explorer.
   3. Navigate to directory to D:\Apps\N3C\Project\
   4. Double click on file N3C_Main.bat to start the N3C data script.
   5. Usual run time for batch file is 8-10 hours.
   6. Can check for errors looking at log file H:\N3C\Project\N3C_debug.log
10. For mini-CDM only, generate and send N3C hash tokens
    1. Go back to the Airflow server from step 1.
    2. Scroll down the DAG list to the entry for STAR_N3C_Hash_Tokens.
    3. Login using PuTTY terminal (or SSH GUI) to same server.
    4. Change directory to /dwhome/airflow_ci/master/dags/CDRN_ETL/Datavant/
    5. Run file hash_token_load_master.sh N3C
    6. Transfer ZIP file created from previous step to local computer
    7. Log into N3C hash token SFTP site (Setup required), 34.132.183.26:2222
       1. Need SFTP private key file
    8. Transfer ZIP file to N3C hash token SFTP site
