AIX: 0403-027 The parameter list is too long (6625591)

Description

On the AIX operating system, some OS-related operations might fail with the following error:

0403-027 The parameter list is too long

Examples of OS-related operations are deploying applications or running the application client container.

This issue is commonly caused by long file paths in the CLASSPATH environment variable.

Solution

Use one of the following solutions:

• Increase the maximum length of the command line. For more information, see (AIX) To Increase the Maximum Length of the Command Line.

• Use the xargs command to construct the argument list and start the command. The xargs command allows commands to exceed the maximum length of the command line.

(AIX) To Increase the Maximum Length of the Command Line

The ncargs attribute determines maximum length of the command line, including environment variables. On the AIX operating system, the default value of the ncargs attribute is four, 4–Kbyte blocks. To ensure that Application Server commands do not exceed the maximum length of the command line , increase this value to 16 4–Kbyte blocks.

After the value of the ncargs attribute is changed, no reboot or refresh of daemons is required.

1. Determine the value of the ncargs attribute.

   lsattr -EH -l sys0 | grep ncargs

2. If the value of the ncargs attribute is less than 16 4–Kbyte blocks, increase the value to 16.

   chdev -l sys0 -a ncargs=16
