Overview

This article provides instructions for easily moving schema changes from one environment to another.

Procedures

Step 1. Make Schema Changes

From your source environment make the desired schema changes via the Schema Designer. Be sure to follow the proper protocol for publishing your schema changes.

Create configuration files using File - Save and Publish in Schema Designer's menu.

Step 2. Extract WSP Tables

<source lang="text">pdm_extract wsptbl > wsptbl.txt pdm_extract -f "SELECT column_name,dbms_name,description,display_name,is_cluster,is_descending,is_indexed,is_local,is_not_null,is_order_by,is_required,is_skey,is_unique,is_write_new,is_wsp,last_mod_dt,on_ci_set,on_new_default,schema_name,status,string_len,table_name,type,xrel_table FROM wspcol" > wspcol.txt</source>

Step 3. Copy Files

Copy the following files from the source to the destination environment:

  • $NX_ROOT/site/mods/majic/wsp.mods
  • $NX_ROOT/site/mods/wsp.altercol
  • $NX_ROOT/site/mods/wsp.altertbl
  • $NX_ROOT/site/mods/wsp_index.sch
  • $NX_ROOT/site/mods/wsp_schema.sch
  • wsptbl.txt (extract from previous step)
  • wspcol.txt (extract from previous step)

Step 4. Load Extracts

On the destination server run the following commands: <source lang="text">pdm_load -if wsptbl.txt pdm_load -if wspcol.txt</source>

Step 5. Publish Schema changes

Follow these steps for publishing the schema changes:

  1. Save and Publish your Schema changes
  2. Stop the Service Desk service
  3. Run pdm_publish from a command line
  4. Start the Service Desk service

Optional Steps

If you want to save SCH and MOD changes in your own file with better name, follow these steps:

  1. Copy content of wsp.mods file to some *.mod in $NX_ROOT/site/mods/majic
  2. Copy content of wsp_schema.sch file to some *.sch in $NX_ROOT/site/mods
  3. Copy content of wsp_index.sch file to some *.sch in $NX_ROOT/site/mods
  4. Delete wsp.mods, wsp_index.sch and wsp_schema files
