When a trusted session is established with a permanent proxy user:

  • Perm space usage for the logged on user is charged to the permanent proxy user.
  • The profile session attributes are set to those of the permanent proxy user.

When a trusted session is established with an application proxy user:

  • The logged on user has no perm space.
  • If a profile is specified on the GRANT CONNECT THROUGH statement for an application proxy user, profile session attributes are set to those of the specified profile. Attributes not specified in the profile are set to the values of the trusted user. If no profile is specified on the GRANT CONNECT THROUGH statement for an application proxy user, session attributes remain those of the trusted user.

For a permanent proxy user, if the user is logged on directly and runs queries and is also logged on to a middle tier with queries being run as a proxy, the SPOOL and TEMP usage accumulation includes both. The individual user’s query fails when the collective usage exceeds the individual user’s limits.
