The table below lists and explains names and meanings of the SAP parameters. These values are tuned by editing the /etc/default/LifeKeeper configuration file.
| Parameter Name | Meaning | Setting Value | Default Value | When to Apply | Notes |
|---|---|---|---|---|---|
| SAP_START_WAIT | Timeout in seconds for the sapcontrol -function StartWait command issued by the restore and recover processes to start the protected SAP instance. | Integers | 228 | As required (takes effect immediately) | |
| SAP_STOP_WAIT | Timeout in seconds for the sapcontrol -function StopWait command issued by the remove process to stop the protected SAP instance. | Integers | 228 | As required (takes effect immediately) | |
| SAP_EXPERTMODE | During LifeKeeper SAP resource creation, the SAP Recovery Kit performs several checks to determine which SAP-related filesystems are shared between nodes and will attempt to automatically create corresponding shared filesystem resources. To disable these checks (e.g., to provide more flexibility when using replicated filesystems), set SAP_EXPERTMODE=1. | 0: Perform filesystem checks and automatically create resources for SAP-related shared filesystems. 1: Skip filesystem checks and do not automatically create resources for SAP-related shared file systems |
0 | As required when creating an SAP resource | Set this parameter value to 1 to prevent the SAP Recovery Kit from automatically creating dependent resources for shared filesystems when an SAP resource is created. This is useful, for example, when SAP-related filesystems are being replicated using DataKeeper. |
| SAP_DB_CHECK_IGNORE | While attempting to start a protected SAP instance, the SAP Recovery Kit checks the status of the associated database (whose information is obtained from the SAPDBHOST/dbtype/dbname/dbhost SAP profile parameters) using an saphostctrl GetDatabaseStatus call. This parameter may be set to 1 to disable the database status check. |
0:Perform database check |
0 | As required (takes effect immediately) | Set this parameter value to 1 if either the database is not protected by SIOS LifeKeeper or if the database check performed by the SAP Recovery Kit is failing unexpectedly. |
| SAP_CONFIG_REFRESH | Refresh time in seconds of the Configuration properties page. | Integers | LKCHECKINTERVAL/2 | As required (takes effect immediately) | If the value is less than 5 seconds, it will be set to the default. |
| SAP_CREATE_NAS | Automatically includes a NAS resource for NAS mounted file systems. | 0: disabled 1: enabled |
1 | As required (takes effect immediately) | |
| SAP_NFS_CHECK_DIRS | Comma-separated list of NFS mount points to check | String | empty | As required when using NFS shared filesystems | Do not use for Amazon EFS mount points |
| SAP_QUICKCHECK_TIMEOUT | Timeout in seconds for the quickCheck process. | Integers | 60 seconds | As required (takes effect immediately) | |
| SAP_RESTORE_TIMEOUT | Timeout in seconds for the restore process. | Integers | 516 seconds | As required (takes effect immediately) | |
| SAP_REMOVE_TIMEOUT | Timeout in seconds for the remove process. | Integers | 804 seconds | As required (takes effect immediately) | |
| SAP_RECOVER_TIMEOUT | Timeout in seconds for the recover process. | Integers | 1320 seconds | As required (takes effect immediately) | If the value is less than the default, it will be set to the default. |
