Managing DECdtm Services

Removing a Node

Enabling DECdtm Services

Disabling DECdtm Services

By default, DECdtm servicesstart automatically when you boot the computer. The DECdtm process, TP_SERVER,then checks for a transaction log, and continues checking untilit finds one.

Disable DECdtm services if you do not use, and do not planto use, any software that uses DECdtm services. This saves memoryand CPU time.

In an OpenVMS Cluster, disable DECdtm services on all thenodes in the cluster.

How to Perform This Task

For each node:
1. Log in tothe node.
2. Stop the TP_SERVER process using LMCP's CLOSE LOG command:
```
$ RUN SYS$SYSTEM:LMCPLMCP> CLOSE LOG
```
  The CLOSE LOG command stops the TP_SERVER process, providing no softwareis using DECdtm services.
  
  If the CLOSE LOG command fails, do not continue this task. If you havealready stopped the TP_SERVER process on other nodes in a clustersystem, restart the process using the SYS$STARTUP:DECDTM$STARTUP.COM command procedure.

Add the following line to the SYS$MANAGER:SYLOGICALS.COMcommand procedure:
```
$ !$ DEFINE/SYSTEM/EXECUTIVE_MODE SYS$DECDTM_INHIBIT yes$ !
```
If you created node-specific versions of SYLOGICALS.COM, editall the versions.

This stops the TP_SERVER process being created the next timeyou boot the system.
