Viewing Active Processes
This section explains how to display statistics for active processes by displaying the task information for the system. By using the show processes command, you can view the system tasks in a table.
The information in this table is useful not only for viewing the process running on the system, but also for obtaining task names and identification numbers (TIDs in this table) for carrying out notify and stop-task commands.
This table contains the following information: names of tasks, entries, task identification codes, priority of a task, status, program counter, error numbers, and protector domain identification.

The following table lists and defines the subcommands and additional capabilities of the show processes command.
show processes Subcommand | Description |
---|---|
sysmand | Statistics for the sysmand process, which is related to the system startup tasks. sysmand starts and keeps track of many of the system tasks. All application tasks send their system log messages to the sysmand task and all notify requests go through sysmand. |
lemd | Statistics for the local element management (lemd) process, which is responsible for maintaining and providing local and remote access to data (including configuration and policy data) stored in the system. |
brokerd | Statistics for the brokerd process, which is a log concentrator and sequencer used for forwarding path and hardware monitor tasks. |
mbcd | Statistics for the mbcd process, which is the process for the middlebox control daemon. It provides signalling applications with the ability to dynamically manage (crete, modify, delete, and receive flow event notifications) NAT entries (pinholes) for media flows via the MIBOCO protocol. |
sipd | Statistics for sipd process statistic, which acts as a SIP server that receives and forwards them on the behalf of the requestor. sipd is responsible for processing SIP (RFC 3261) messages. It NATs the Layer 5 signaling content (for example, SIP message headers) and manages the associated media flows via tMBCD. |
current | Current statistics for all processes. |
total | Total statistics for all processes. |
all | All statistics for all processes. |
cpu | Percentage of CPU utilization by all processes. |
Viewing Statistics for all Processes
Display the statistics for all processes by using the show processes all command.

Checking Remaining Space
Check the amount of storage space is available on the flash file system on the following devices by using the check-space-remaining command:
- /boot
- /code
- /crash
- /opt
- the data-disk, system-disks or a combination
For example:
ORACLE# check-space-remaining boot
boot: 20127744/29760512 bytes (67%) remaining
SMP-Aware Task Load Limiting
The ability to manage CPU load is critical for highly available devices. SMP architectures require unique load limiting because a task’s threads may be spread out over several cores. The Oracle Communications Session Border Controller employs a method of determining aggregate load in its SMP environment so that resources may be evenly spread across all CPUs and applications can decrease their load when necessary. In turn, traffic may be dropped or rejected depending on the application to reduce the CPU load to an acceptable value.
Load limiting can be performed on three fundamental processing areas of the Oracle Communications Session Border Controller:
- Transport Limiting — When the system’s CPU load rises above the transport limiting value, traffic received from endpoints is dropped. The system scales back the load of the processes where network packets (TCP, SCTP, and UDP) are disassembled.
- Media Limiting — When the system’s CPU load rises above the Media limiting value, the process that creates end-to-end media interface connections begins to drop requests (changes to existing transport sessions can still occur) thereby reducing CPU load. The system replies to SIP requests that initiate transport sessions with 503 Service Unavailable (this would typically be an INVITE with SDP).
- SIP Limiting — The system can manage percent CPU utilization by limiting the number of SIP messages it processes, as follows:
- Begins rejecting SIP requests when the CPU reaches its throttling threshold, and
- Rejects all SIP requests when the CPU reaches its maximum utilization.
Calculating CPU Load Limits
This section explains how and when the Oracle Communications Session Border Controller performs SIP message throttling to limit CPU utilization. This configuration also affects IDS management information.
The Oracle Communications Session Border Controller limits CPU utilization by SIP requests using two utilization percentage points. When CPU utilization reaches the first point, the system begins to reject SIP requests. When it reaches the second point, the system rejects all SIP requests. By default, these values are 90% and 99%. The user can change these values using a sip-config option called load-limit.
The load-limit option accepts two parameters, from which it determines these levels, including:
- Minimum CPU Utilization - The CPU utilization percentage at which the system begins to throttle back on the SIP requests it processes.
- CPU Limit for Headroom Calculation - A variable the system uses to compute maximum CPU utilization, at which it stops accepting SIP requests.
Syntax for this option is:
load-limit= < Minimum CPU Utilization > [-< CPU Limit for Headroom Calculation >]
User settings include:
- Minimum CPU Utilization - The range is 15% to 100%, and the default is 90%.
- (Optional) CPU Limit for Headroom Calculation - The range is 15 to 100, and the default is 100.
The calculation the system uses to determine the maximum CPU percent utilization is shown below, with X representing the Minimum CPU Utilization, and Y representing the CPU Limit for Headroom Calculation.
X + ((Y - X) * X/Y)%
The example setting below sets the throttling threshold to 60% and the maximum utilization to 75%.
load-limit= 60-80
The calculation the system uses is 60 + (80 - 60) * 60/80 = 75
The system progressively rejects requests as CPU utilization increases. When CPU utilization is between X% and the maximum, the system accepts some new SIP requests, depending on CPU utilization and utilization configuration. The system calculates this acceptance rate using the formula below.
100 - ((Current CPU Util - X) * 100 / ((Y - X) * X/Y))
When CPU utilization reaches its maximum, it drops all new SIP requests. The system resumes accepting requests when CPU utilization falls below its maximum, and stops throttling when it falls below the Minimum CPU Utilization.
While rejecting a SIP request, the system returns a 503 service unavailable message, along with a Retry-After header. The user can configure the reject-interval using the sip-config's reject-interval=X option. The default value is 1 second.
The actual value of reject interval header embedded in the 503 message is:
RetryAfter = (100 - Acceptance Rate) /10 * rejectInterval
If this value is smaller than the configured reject-interval, the system overwrites it with the configured reject-interval value.
Note the table below, which displays some valid and invalid configuration entries.
User Configuration | Headroom | Max CPU Limit | Configuration Valid? |
---|---|---|---|
load-limit=60 | (100 - 60) * 60 /100 = 24 | 60+24 = 84 |
Yes |
load-limit=60-80 | (80 - 60) * 60/80 = 15 | 60+15 = 75 |
Yes |
load-limit=80-60 | (100 - 80) * 80 / 100 = 16 | 80+16 = 96 |
No - (Upper limit < Lower limit) |
load-limit=80-101 | (100 - 80) * 80 / 100 = 16 | 80+16 = 96 |
No - (Upper limit > 100) |
