Mrs,

Where do I can set starting memory usage of CAS?

Is it a file?
Is it in the "ATSCON"?

I need to allocate more memory cas.

I'm looking for the answer in the manual, but still can not find it

thank for the help.

Hi Carlos,

You can increase the memory for the CAS(ADS) by editing the regedit key in the following way. Please make a backup of the key before you edit it.

  1. Regedit-->HKEY_LOCAL_MACHINE-->SOFTWARE-->ADLEX–>Compuware Central Analysis Server (on the CAS Machine)–>Edit the Xmx parameter in the javaParams argument. Right click and click modify.
  2. Regedit-->HKEY_LOCAL_MACHINE-->SOFTWARE-->ADLEX–>Compuware Advanced Diagnostics Server (on the CAS Machine)–>Edit the Xmx parameter in the javaParams argument. Right click and click modify.
  3. The Xmx value is defined in MB, so for example 32 GB would be (32*1024 = 32768)
  4. Restart the CAS service.

 

Please let me know if you have any questions.

Regards,

Harshal.

thanks for the reply.

In the case that my server has 64 GB of memory and I have installed SQL CAS + CAS
How much is it advisable to assign?

My software version is 12.0 Sp2 CAS

Hi Carlos,

Based on the recommendations mentioned here, you should be good. However, depending on your environement,  the CAS might need more memory. Are you experiencing memory issues?

Regards,

Harshal.

  1. How much memory you have assigned to the CAS currently ? 
  2. How much memory is free in the system ? 
  3. What is the distribution of memory among RUM Console, CAS and SQL Server  ?
  4. How many raw sessions do you store in the CAS ?

Mr,

here my answers

How much memory you have assigned to the CAS currently ?  24 GB Ram

How much memory is free in the system ? I have 17GB free, I currently have 48 GB but soon we will assign 64GB

 

What is the distribution of memory among RUM Console, CAS and SQL Server  ?

to SQL 20 GB

I do not know where to see how much memory is assigned the DCRUM

 

How many raw sessions do you store in the CAS ?

Information of System status

Memory information of System Status.

 

I'm not clear yet because all the memory is consumed and CAS takes my resources and I must restart the service, this happens every 7 to 10 days.

thank.

Increase the memory of the CAS to 32GB. 

If issue still persists, I'll have to create a support ticket to investigate that further individually.

One additional question that came to my mind :

Do you have the Enterprise Portal deployed in your environment ?

Mr,

I have the EnterprisePortal in my environment but on another server with BSM.

 

thanks for you help.

We have some cases where the Enterprise Portal caused CAS to utilize more memory. If you have EP connected to the CAS with memory issue, you should think of disconnecting the CAS from EP.

What other solution is there? I need to do the integration of CAS with PortalEnterprise,
at this time we are in version 12.0 Sp2,
this problem of memory consumption PortalEnterprise with CAS is fixed in version 12.1 SP2?.

 

thank
