CA CSM Application Server Error in MSMLOG File

Symptom:

I see the following error message in the CA CSM application server MSMLOG file:

WARNING: Error reading /dev/urandom
Throwable occurred: java.io.FileNotFoundException: /dev/urandom (EDC5157I An internal error has occurred.)
 at java.io.FileInputStream.<init>(FileInputStream.java:112)

Reason:

This message only appears when both of the following conditions are met:

• You have installed PTF RO21996 on CA CSM r2.0 (FMID CEG1200).
• The IBM Integrated Cryptographic Service Facility (ICSF) has not been started on the z/OS system where the CA CSM application server session is running.

Solution:

The appearance of this message in no way affects the performance of CA CSM, and CA CSM will continue to function. If you want to verify that dev/urandom is running and is compatible with CA CSM, use the following command:

$ cat </dev/urandom | head -c12 | od -X

The command has to return random data without any error. For example:

0000000000          60621BCF        8AAD1F12        8944D619
0000000014

If the device is not working, a warning message appears. For example:

FSUM7343 cannot open "/dev/urandom" for input: EDC5157I An internal error
has occurred.
0000000000

If you see this error message, reconfigure your /dev/random device in order that the command can successfully read from this device.

Note: For more information about the /dev/random device, see the IBM z/OS V1R10.0 UNIX System Services Planning (GA22-7800-14).
