Issue/Introduction

Running script with REST API calls to the AdminUI like this:

   #!/bin/bash

       echo "Token :";
       echo $myToken;

       for i in `seq -w 1000`; do myToken=`curl -k -u siteminder:password -X POST https://adminui.training.com:8443/ca/api/sso/services/login/v1/token | grep sessionkey | gawk -F: '{print $2}' | grep "\"" | gawk -F\" '{print $2}'`; curl -k -H "Authorization: Bearer $myToken" -H "Content-Type: application/json; charset=UTF-8" -X POST --data @agent$i.json https://adminui.training.com:8443/ca/api/sso/services/policy/v1/SmAgents -v; done; 

The AdminUI reports:

server.log :

The AdminUI also quickly uses more memory:

Environment

 

  AdminUI 12.8SP5 on RedHat 7;
  Policy Server 12.8SP5 on RedHat 7;

 

Resolution

 

Put the code to get the token outside the loop code like this:

   #!/bin/bash

   myToken=`curl -k -u siteminder:password -X POST https://adminui.training.com:8443/ca/api/sso/services/login/v1/token | grep sessionkey | gawk -F: '{print $2}' | grep "\"" | gawk -F\" '{print $2}'`

   if [ -z "myToken" ]; then

       echo "null";

   else

       echo "Token :";
       echo $myToken;

       for i in `seq -w 1000`; do curl -k -H "Authorization: Bearer $myToken" -H "Content-Type: application/json; charset=UTF-8" -X POST --data @agent$i.json https://adminui.training.com:8443/ca/api/sso/services/policy/v1/SmAgents -v; done; 

Each instantiated session to handle a REST API call requires intensive
memory. As such, a single session is necessary when executing a
batch. This session should be renewed every 15 minutes as stated in
the documentation (1).

 

Additional Information

 

(1)

    Policy Object REST APIs

      Each call to the Policy Data API and Policy Migration API requires a
      valid JWT. Use the Administrative Token API to obtain that token.

      The Administrative Token API provides a single call that receives
      the credentials (username and password) of a SiteMinder
      Administrator in the Authorization header. If Basic authentication
      for that administrator account is successful, the API returns a JWT
      containing a session ticket.

      Warning 

      The JWT expires after 15 minutes after which it must be refreshed.
