NetBackup status code: 89
Message: problems encountered during setup of shared memory
Explanation: The NetBackup processes use shared memory for some operations. This status is returned when an error is encountered in the initialization of the shared memory by the operating system's APIs.
Recommended Action: Check for a shared memory problem. This error can occur if the system cannot allocate enough shared memory. It usually occurs with multiplexing, which increases the amount of shared memory that is required for the operation. An entry similar to the following may be seen in a NetBackup log or report:
system cannot allocate enough shared memory
If you see this type of message, refer to your platform vendor documentation for instructions on how to increase shared memory on your system.
For older levels of Solaris, you may need to change one or more default System V Shared Memory settings to prevent jobs failing with the memory allocation message, as follows:
For Solaris 9, the default shminfo_shmmax value is 8 megabytes. You can place the following line in your
/etc/systemfile to increase this setting. A value of 32 megabytes has been used in this example. Your system may require a greater value under some circumstances such as a high value for the NetBackup multiplexing parameter. According to Sun Microsystems documentation, setting this parameter to its maximum possible value has no side effects. (This parameter is not applicable to Solaris 10).set shmsys:shminfo_shmmax=33554432
For Solaris 9, the default shminfo_shmmni value is 100. You can place the following line in your
/etc/systemfile to increase this setting. The default value is usually sufficient for NetBackup. In some circumstances, such as installing a NetBackup media server on a large database server, this setting may need to be increased. A value of 220 has been used in this example. (This parameter is not applicable to Solaris 10).set shmsys:shminfo_shmmni=220
Note:
If you modify any of these values in the /etc/system file, you must restart the system with boot -r for the new settings to take effect.
Refer to your vendor documentation for detailed instructions on how to modify these values. Note that these shminfo parameters are not applicable to Solaris 10.
