Use the syscadm script to configure and administer Adaptive Server resource groups and their associated resources in Sun Cluster. You can use syscadm to create, remove, or no longer control the Adaptive Server resource group and its resources. The syscadm script is located in $SYBASE/$SYBASE_ASE/SC-3_0/bin/.
The create option of the script:
Registers required resource types with the Resource Group Manager
For each specified resource group, creates the resource group, specified resources and adds them to the resource group
Establishes resource dependencies for the Adaptive Server resource on the storage and logical host resources
The remove option in the script removes specified resource groups and their resources.
The unmanage option:
Disables all the resources in the resource group
Brings the resource group to an offline state, then brings the resource group to the unmanaged state
You must be logged in as “root” to
run the syscadm.
syscadm works with an input file called sysc_input_file, which you edit to provide the correct input values for your configuration. The sysc_input_file is located in $SYBASE/$SYBASE_ASE/SC-3_0/etc/.
Make sure the file is not tampered with when you finish
editing the sysc_input_file.
If erroneous values are included in this file, they may affect your
installation. Sybase suggests that you change the permissions on
this file so only System Administrators can edit it.
When editing the sysc_input_file, make sure that:
There are no spaces around “=” in
the “<name>=<value>” entries.
Comments start with #.
Names ending with 1 correspond to the primary companion.
Names ending with 2 correspond to the secondary companion.
See “Sample sysc_input_file” for a sample of the sysc_input_file.
The input file is divided into three sections.
Section 1 – enter the right-side values for all entries. This section includes entries for the Adaptive Server installation directory, the high availability setup, the data server name, the Nodelist, and so on.
Section 2 – enter right-side values for the required entries. For example, if you are using only the SUNW.HAStoragePlus resource, you must enter values for SUNW.HAStoragePlus-related entries. Do not enter values for the entries you are not using.
Section 3 – all the entries in this section are assigned default values. You need not provide right-side values except to override the defaults.
For example, to edit the file for the Adaptive Server resource name, change this line:
ASE_RNAME="ase_$Dataserver_name"
To:
ASE_RNAME="my_ase_name"
Or, to specify the RUN_SERVER file and to set Debug_callback flag, change the entry for OTHER_PROPERTIES, whose value is a space-separated list of <name>=<value> strings, to:
OTHER_PROPERTIES="RUN_server_file=/mypath/RUN_my_ase Debug_callback=TRUE"
