Configure a variable map

 

This example creates a variable map to an existing server.

1. Idenitfy the server and assign it to the server variable.

   set server [$AdminConfig getid /Cell:cellname/Node:nodename/Server:server2/]
   

2. Create an empty variable map for the server and assign it to the varMap variable.

   set varMap [$AdminConfig create VariableMap $server {}]
   

   This example is to create a variable map. If your server already has an existing variable map, then you can use the following to get its configuration object:

   set varMap [$AdminConfig getid /Cell:cellname/Node:nodename/Server:server2/VariableMap:/]
   

3. Set up variable map entry attributes.

   In the following example, you create variable map entries DB2_INSTALL_ROOT and DB2_LIB_DIR. DB2_LIB_DIR is going to refer back to DB2_INSTALL_ROOT:

   set nameattr1 [list symbolicName DB2_INSTALL_ROOT]
   set valattr1 [list value "/usr/local/db2/sqllib"]
   set nameattr2 [list symbolicName DB2_LIB_DIR]
   set valattr2  [list value  "\${DB2_INSTALL_ROOT}/lib"]
   set attr1 [list $nameattr1 $valattr1]
   set attr2 [list $nameattr2 $valattr2]
   set attrs [list $attr1 $attr2]
   

   Example output:

   {{symbolicName DB2_INSTALL_ROOT} {value /usr/local//db2/sqllib}} {{symbolicName DB2_LIB_DIR} {value {${DB2_INSTALL_ROOT}/lib}}}
   

4. Modify the entries attribute in the variable map to add the two new entries.

   $AdminConfig modify $varMap [subst {{entries {$attrs}}}]
   

5. To view the variable map:

   $showall $varMap
   

   Example output:

   {entries {{{symbolicName DB2_INSTALL_ROOT}
   {value /usr/local/db2/sqllib}} {{symbolicName DB2_LIB_DIR}
   {value ${DB2_INSTALL_ROOT}/lib}}}}
   

6. Save changes:

   $AdminConfig save
