VCS Agent for Sybase can't bring online Sybase ASE

Is the issue that VCS does not detect the ASE is online at all, or is it that the ASE is taking a longer time to come up than VCS is expecting (timing issue)?

If it's the latter, can you try increasing OnlineWaitLimit for the Sybase resource type so it waits longer for before deciding the ASE is offline? (the default is 2, so since you said that you can connect to it right before it's shutdown, perhaps try increasing to 4 so it tries 4 times instead of twice?)

See VCS User's Guide -> Appendixes -> VCS attributes -> Resource type attributes:

http://sfdoccentral.symantec.com/sf/5.0MP3/solaris/html/vcs_users/ap_vcs_attributes4.html
--------------------
OnlineWaitLimit (user-defined)
Note: This attribute can be overridden.

Number of monitor intervals to wait for the resource to come online after completing the online procedure. Increase the value of this attribute if the resource is likely to take a longer time to come online.
* Type and dimension: integer-scalar
* Default: 2
--------------------

If you have tried this and the problem is that the agent never detects the ASE, then please provide additional details to investigate, at minimum:

- OS/platform
- VCS version
- VCS configuration (main.cf)

hope that helps,

Hi,

Have you tried onlining this ASE outside VCS ? If you can try this, it will clearly give you indications on how much time it takes to come online. Once you have the exact timelines, you can define the parameters accordingly in VCS.

I am assuming that every thing is working as expected outside to VCS.

In addition to what Grace suggested, you can also tweak around OnlineTimeout, tolerencelimit etc.

Have a look around VCS user's guide to know more about these tunables. You can find the user's guide on below link, check for your OS & veritas version

Hi,

Have you configured Detailed Monitoring on the Sybase Resource? If so, please set it to 0, and retry the monitor operation. If you find that the resource probe show that it is now online, please check your detailed monitoring configuration.

It could be that because you've set detailed monitoring, VCS is not able to access the table, or the user account isn't granted access, etc, etc.

Hi,

Yes, I've configured detailed monitoring but disabling or enabling it doesn't change anything.

Can you post the log for sybase from /var/VRTSvcs/log/ here please.

Hi

OS: Sun Solaris 10 x86 on Vmware ESX 4.0

VCS version: 5.1

Sybase ASE 15.5

VCS config:

 DataMount requires Syb_DiskGroup_Data
 Syb_IP requires Syb_NIC
 Syb_Sybase requires DataMount
 Syb_Sybase requires Syb_IP

 // resource dependency tree
 //
 // group SybaseASE
 // {
 // Sybase Syb_Sybase
 //     {
 //     Mount DataMount
 //         {
 //         DiskGroup Syb_DiskGroup_Data
 //         }
 //     IP Syb_IP
 //         {
 //         NIC Syb_NIC
 //         }
 //     }
 // }

Still the agent can't detect that ASS is online and shortly after ASE start shutdowns it. By the way how does the agent check if ASE is online?

Thank you very very much for this tip. It indeed solves the problem.

I think that Veritas Cluster Server Agent for Sybase Installation and Configuration Guide must have that request to rewrite RUN script
